[7bc4300]2
3Changes in 1.4.6 (2024-02-??):
4
[752a9f5]5* aven,survexport: Enable export of surface legs for KML and JSON.  Currently
6  surface and underground legs aren't differentiated in these export formats
7  when both are enabled.
[7bc4300]8
[752a9f5]9* aven,survexport: Fix survey filtering when reading Compass PLT files.
10
11* Update build system to eliminate use of obsolete autotools macros.
12
13* cavern:
14
15  + Workaround bug in PROJ < 9.3.0 with projected coordinate systems with
16    northing/easting axis order (such as EPSG:3042) which results in the grid
17    convergence being wrong by about 90°.  Reported by Patrick Warren on the
18    mailing list.
[7bc4300]19
[752a9f5]20  + If *declination auto was used before *cs out we would incorrectly calculate
21    the grid convergence as 0.  We now handle this case correctly by
22    calculating lazily when we first read a compass reading, and report an
23    error if the output coordinate system hasn't been set by then.
24
[e5e93f9]25  + Surveys in Compass DAT files which indicate a depth gauge was used for
26    azimuth readings are now marked as STYLE_DIVING in the 3d file.
27
28  + We now parse the "CORRECTIONS2" field in newer format Compass DAT files
29    which specifies corrections for backbearing and backazimuth.  Previously
30    cavern ignored this field.
31
32  + The tape correction in Compass DAT files is now handled correctly.  The
33    specified value is in feet, but cavern was incorrectly treating it as
34    being in metres.
35
36  + We now handle newer format Compass DAT files with a 15 character "FORMAT:"
37    specification.  Previously cavern wouldn't detect when there were backsights
38    in this case.
39
[752a9f5]40* aven: Fix OpenGL scaling on high DPI displays with wxWidgets 3.0. Reported by
41  Philip Balister.
[7bc4300]42
43* manual: Improve NATO mils example.
44
45* INSTALL: Clean up text re -dev packages
46
47* INSTALL: Add a link to the instructions for building from git.  Reported by
48  Andrew Northall in https://github.com/ojwb/survex/pull/13
49
[752a9f5]50* doc/TODO.htm: Update.
[7bc4300]51
[b1c66e1]52* (Microsoft Windows version): Now using wxWidgets 3.2.4 (was 3.1.6).
53
[7bc4300]54* Fix compilation warnings from newer compiler versions.
55
[e5e93f9]56* The source code now assumes difftime() is available since it was standardised
57  in C89 and we're not aware of any current platforms which lack it.
58
[752a9f5]59* img library:
60
61  + Improve Compass PLT support: Survey dates are now handled; LRUD data is now
62    translated to img_XSECT and img_XSECT_END; We now infer img_SFLAG_ENTRANCE
63    for stations where the "Distance From Entrance" field is present and zero.
[e5e93f9]64    The shot flags field in newer format PLT files is now translated to
65    img_FLAG_DUPLICATE and img_FLAG_SPLAY; the 'd' plot command is now
66    supported.
[752a9f5]67
68  + Fix bug handling timestamps before 1970.  In C signed integer division
69    rounds towards zero, which previously resulted in timestamps before 1970
70    getting rounded to the end of the day instead of the start when converting
71    them to a count of days so they'd be off by one day unless the time was
72    midnight.  This affected reading v3-v7 format 3d files with IMG_API_VERSION
73    set to 1 and writing v8 format 3d files with IMG_API_VERSION set to 0 (the
74    default).
75
[a30f7d0]76Changes in 1.4.5 (2023-06-29):
[1a67f93]77
78* aven: Fix rendering of crosses when drawn as sprites.  Reported by echarlie.
79
80* (macOS version): aven: Fix crash in export dialog.  Fixes #133, reported by
[a30f7d0]81  rixyane.  Thanks to Wookey for testing.
[1a67f93]82
83* manual: Expand docs on connecting to Compass data.
84
85* Minor translation updates.
86
[269106c]87Changes in 1.4.4 (2023-02-03):
88
89* aven: Fix red line in clino background to be grey (this was introduced in
90  1.4.3 and was a debugging change accidentally left in).
91
92* aven: Accept weird .3d files from Therion which have empty components in
93  station names.  That's not really valid by Survex's definition of station
94  names, but it's not very helpful to reject such files, so just disable the
95  checks that were rejecting this.
96
97  The result is empty entries in the survey tree, but I don't see what we can
98  really do that's better than that.
99
100  Reported by Vasily Vl. Suhachev.
101
102* aven: Make it more obvious you can enter a custom scale by adding a "..."
103  entry to the scale combobox - selecting this clears the value and gives focus
104  to the combo box text entry. This control has always supported clicking to
105  enter a custom scale, but there wasn't really any indication that this was
106  possible before.  Partly addresses #132, reported by Eric C. Landgraf.
107
108* aven: Force export window to resize when the export format is changed as
109  different controls are shown depending on the export format.
110
111* aven: Right-align tilt spin control value in print/export dialog to match the
112  bearing spin control.
113
114* aven,survexport: Add ability to export as Survex 3d which is useful as you
115  can filter to a subset of surveys, filter out splays, convert from other
116  formats the img library can read, etc.  This feature is a bit rough and ready
117  currently but please report issues.
118
119* dump3d: Add --legs option which converts MOVE and LINE to a single LEG line
120  per leg with the from and to coordinates.  Tools which parse dump3d output
121  should find this easier to process as it avoids having to track a "current
122  position".
123
124* Update manual to have a complete list of quantities which *calibrate accepts.
125  Reported by echarlie
126
127* cavern.tst: Fix testsuite to work with SOURCE_DATE_EPOCH set.
128
[fcf3d2e]129Changes in 1.4.3 (2022-05-17):
[4c0900b]130
[4659b8a]131* aven: Much improved support for HiDPI monitors on all platforms.
[4c0900b]132
133* aven: When started without a file make sure the window has focus so menu
134  accelerators and shortcuts work without clicking on the window.
135
136* aven,survexport: DXF export now puts splays in a separate layer and uses a
137  dotted linetype for them.  Patch from echarlie, see #60.
138
139* Improved survexport man page to include command line options and a short
140  note about DXF export.  Patch from echarlie.
141
[4659b8a]142* Minor translation updates.
[4c0900b]143
[4659b8a]144* (Unix version): aven: Fix handling of EGL-based wxGLCanvas (which wxGTK 3.1.5
145  has).  Fix a build failure and don't force X11 (as the EGL-based wxGLCanvas
146  works on Wayland).
[4c0900b]147
148* (MacOS version): aven: Fix hang on startup without a file.  Fixes #120,
149  reported by Enrico Fratnik.
150
[fcf3d2e]151* (Microsoft Windows version): Now using wxWidgets 3.1.6 (was 3.0.5).
152
[4659b8a]153* img library: Support reproducible builds which create .3d files by not
154  embedding a timestamp if environment variable SOURCE_DATE_EPOCH is set.
155  Requested by Martin Budaj.
156
[a33237fd]157Changes in 1.4.2 (2022-02-25):
[d2b22b1]158
159* aven: Fix to be compatible with FFmpeg 5.0.
160
161* Improve docs for *cs and *declination.
162
[48d5a6f]163* cavern: Fix "*declination auto" not to crash when built with PROJ < 8.1.0.
164  Bug introduced in 1.4.0.
165
[a33237fd]166* cavern: For each `*declination auto` command cavern now reports an "info"
167  message showing the range of calculated declination values and the dates at
168  which the ends of the range were obtained, and also the grid convergence
169  (which doesn't vary with time).  Fixes #92, reported by Rob Eavis.
170
[48d5a6f]171* cavern: If any of the N-S, E-W or U-D ranges includes an anonymous station
172  then also report the range in that direction excluding anonymous stations.
173  Patch from Thomas Holder.
174
175* cavern: The error from a bad `*cs custom` command now highlights the quoted
176  string properly.
[d2b22b1]177
[a33237fd]178* cavern: "FIX command with no coordinates - fixing at (0,0,0)" is now an
179  "info" rather than a "warning".  It's not really reporting a problem and the
180  ability to omit the coordinates is a deliberate feature.  It is useful for
181  the user to know where the "*fix" without coordinates is if they want to
182  change the survey to be in real coordinates, so an "info" diagnostic is a
183  good fit.  This also means aven will no longer stay on the log view after
184  processing a dataset which fixes without coordinates.
185
186* cavern: If "*fix" is used twice with no coordinates we no longer say
187  "FIX command with no coordinates - fixing at (0,0,0)" right before:
188
189  error: Already had FIX command with no coordinates for station "x"
190
[d2b22b1]191* cavern: Include errors in Compass .mak files now report the error in the line
192  where the included filename is actually specified.
193
194* cavern.tst: Add test coverage for warnings for *entrance and *export with
195  a station which doesn't exist otherwise.
196
[a33237fd]197* aven/survexport: Change JSON export to be valid JSON.  This means the output
198  has changed incompatibly, but it wasn't valid JSON before which suggests
199  nobody was actually successfully using it. Fixes #128, reported by Pawczak.
200
[48d5a6f]201* aven.tst: Skip one testcase on macos as it seems to hang, at least when
202  running on the Continuous Integration system.
203
[a33237fd]204* (Microsoft Windows version): The installer is now generated with a much
205  newer version of Innosetup.  Most notably, it now supports installing as a
[812a8d7]206  non-admin user.  This also means Microsoft Windows Vista is now the minimum
207  supported version but 2000 and XP are both many years out of support anyway.
[a33237fd]208
209* (Microsoft Windows version): The coordinate system database for PROJ is
210  now included so "*cs" now works (broken since 1.4.0).
211
[d2b22b1]212* Chinese translation updates from Qingqing Li.
213
[d8f00a9]214* Building from source now requires a compiler with support for C99.  C99
215  seems to be universally supported by compilers now so we don't expect this to
216  inconvenience anyone.
217
[570b57d]218Changes in 1.4.1 (2021-11-08):
219
220* This release should work with any PROJ version >= 6.2.0.
221
222* cavern.tst: Fix to actually run tests when building outside the source
223  tree.  Previously files for testcases weren't found, and tests were skipped
224  with a warning, which lead to 1.4.0 being released with two failing testcase.
225  Fix to find the files, and make not finding them an error.
226
227* cavern.tst: Fix testcases gpxexport and require_fail which were failing
228  in 1.4.0.
229
230* 3dformat.htm: Document that coordinate system can be ESRI:<number>.
231
[67f9739]232Changes in 1.4.0 (2021-11-06):
[3b69f29]233
234* New release series to mark that Survex now uses the new PROJ API, and
[cccc545]235  requires PROJ >= 7.2.0.  Survex 1.2.x will continue to support PROJ < 8
236  (and won't support newer PROJ versions).  Fixes #102, reported by Bas
237  Couwenberg.
[3b69f29]238
239  Due to these changes, PROJ will now convert directly between coordinate
240  systems where it knows how to, instead of always converting via WGS84.
241  This means conversions may now be more accurate in some cases, and you may
242  notice station coordinates changing - these should be for the better.
243
244  Also, the vertical datum is now taken into account automatically, and
[e91c656]245  terrain data now aligns much better vertically with surveys.  Fixes #56.
[3b69f29]246
247* aven: Clicking and holding the left mouse button on the compass or clino,
248  then (while still holding) clicking the right button no longer causes a
249  wxWidgets assertion to fail.  Reported by echarlie.
250
251* img library: Rewrite certain proj strings when reading 3d files for
252  better compatibility with newer PROJ versions, where use of proj
253  strings is strongly discouraged.
254
255  `+init=epsg:` followed by a code number is rewritten to `EPSG:`.
256
257  `+init=esri:` followed by a code number is rewritten to `ESRI:`.
258
[67f9739]259  The proj strings which cavern used to put in 3d files for UTM zones and
260  S-MERC are rewritten to `EPSG:` follow by the appropriate code number.
[3b69f29]261
262* Also install survex.lang for gtksourceview 4. Fixes #125, reported by Martin
263  Green.
264
265* Fix missing data style in interleaved example in manual.  Reported by
266  echarlie.
267
268* Use jw from docbook-utils instead of sgmltools-lite to process the manual.
269  The sgmltools-lite homepage says it's no longer being developed, and suggests
270  docbook-tools (which Debian packages as docbook-utils) as a replacement.
271
272* doc/HACKING.htm: Update Debian packages to install
273
[67f9739]274* doc/HACKING.htm: Update details of setting up mingw cross-build environment.
275
[3b69f29]276* Add simple tests for GPX and KML export.
277
278* Expand cavern testcase csbad.
279
280* cavern.tst: Parse warning/error counts more robustly.  Previously we'd get
281  confused if the final line just contained an integer, e.g. if we end listing
282  stations not attached to a fixed point.
283
[738af38]284Changes in 1.2.45 (2021-03-09):
285
286* Avoid undefined signed shifts in 3d file handling.  Survex itself is only
287  affected on big-endian platforms (so most Linux machine, Microsoft Windows,
288  and current Macs are all OK), but this also affects the img library on all
289  platforms when used in standalone mode as it is in other programs.  Fixes
290  #119, reported by Matěj Plch.
291
292* aven:
293
294  + When reading cavern output for the log window, we need special handling
295    for the case when a chunk of output ends mid-way through a UTF-8
296    sequence.  Previously we lost the first byte of the sequence in this
297    case (and would then show it as an invalid character), but now it is
298    handled correctly.  In practice, most of the cavern log output is ASCII so
299    it's quite possible nobody's ever actually hit this.
300
301* testsuite:
302
303  + Suppress reports of leaks on exit from the LeakSanitiser debugging tool.
304    We know we don't release all memory explicitly on exit since doing so would
305    mean extra work for no reason as the OS reclaims all memory when the
306    process exits.
307
308* Convert OLDNEWS encoding from ISO-8859-1 to UTF-8.
309
[38bc415]310Changes in 1.2.44 (2021-02-10):
311
312* aven:
313
314  + (Microsoft Windows version): Now using wxWidgets 3.0.5 (was 3.0.4).
[f9de21a]315
316* cavern:
317
[66b477f]318  * Add support for quadrant bearings (e.g. N30E).  Patch from echarlie.
319
320  * Report error if angle units are specified for passage dimension.
321    Previously "*units left degrees" and similar were incorrectly quietly
322    accepted.  Spotted by echarlie.
323
[f9de21a]324  * Fix *data with no parameters to keep the current style and reset any state
325    as documented.  Previously it actually instead ignored any survey data
326    until the next *data command with parameters.
327
328  * Fix minor memory leak in *data.  We leaked a single memory allocation on
329    "*data default" or an invalid *data command.
330
331  * Improve test coverage.
332
333* survexport:
334
335  * The check for whether a format supported --elevation, --plan, --bearing and
336    --tilt was inverted.  Reported by echarlie.
337
338  * Fix reporting of export errors on Microsoft Windows.  Reported by Matic Di
339    Batista.
340
341* img library: Fix img_open() when used in other programs.  Patch from Thomas
342  Holder.
343
[66b477f]344* configure: Add wx-config-gtk3 to WX_CONFIG search for Arch Linux.  Patch
345  from Thomas Holder.
346
[f9de21a]347* Improve documentation of interleaved data.  Most notably, we now document
348  that a blank line breaks the current traverse.
349
350* Fix typo in manual ('cypolar' -> 'cylpolar').  Patch from Wookey, fixes #117.
351
352* Chinese translation updates from Qingqing Li.
353
354* Russian translation updates from Vasily Vl. Suhachev.
355
356* French translation updates from Jean-Marc and from Wassil Janssen.
357
358* Bulgarian translation updates from Wassil Janssen
359
[fe8a1b4]360Changes in 1.2.43 (2020-02-28):
361
362* cavern: Update to use v13 of the IGRF model for calculating declinations.
363  This was issued in December 2019 and should give slightly more accurate
364  declinations for surveys made since 2010.
365
366* aven:
367
368  + Fix colouring of "not in loop" when colouring by error.  1.2.42 introduced
369    a bug where surveys not in a loop were coloured as if they had zero error.
370    Fixes #111, reported by Bruce Mutton.
371
372  + Fix handling of grid in export.  The grid was always getting enabled
373    (probably since 1.2.8) even for formats which don't support exporting with
374    a grid.  This resulted in the bounding box being set wrongly for some
375    formats such as SVG, as reported by Richard Knapp on the mailing list.
376
377  + When showing errors processing the survey data we'd previously crash if
378    cavern incorrectly reported an error as being in a column off the end of
379    the line - now we just ignore the error column in this case.
380
381  + Support colouring by survey style ("normal", "diving", "nosurvey", etc).
382
[040c02e]383Changes in 1.2.42 (2019-09-04):
384
385* aven:
386
387  + Allow colouring by horizontal or vertical error.
388
389  + (Unix version): Disable scaling for HiDPI displays with GTK3.  The OpenGL
390    code needs work before this will work usefully, so just disable for now
391    (which simulates how things are when using GTK2).
392
393  + (Unix version): Fix orientation of notebook tabs when build with wxWidgets
394    3.1 development versions.  We want horizontal tab orientation, but were
395    passing a weird flag combination which now results in vertical tab
396    orientation.
397
398* When exporting to a format where we support rotation in the horizontal
399  plane (such as SVG), the rotation was incorrectly applied to cross section
400  data (except for the default rotation of zero).  Fixes #108, reported by
401  Richard Knapp.
402
403* Add a section to the manual covering the command line tools, and what you
404  might still need to use them for.
405
406* Fix compiler warning when building from source with GCC 9.
407
408* Consistently refer to macOS not OS X - Apple have renamed it yet again.
409
410* (macOS version): Revert the workaround for the crash on macOS 10.14.  The
411  bug we were working around is fixed in git ready for wxWidgets 3.0.5 and
412  there's a backported fix in the homebrew wxmac 3.0.4-2 package, which is how
413  we now recommend people install on a Mac.  Closes #101, reported by floho.
414
415* (macOS version): Remove buildmacosx.sh script since installing from homebrew
416  is now the recommended approach.
417
[0957d63]418Changes in 1.2.41 (2019-07-10):
419
420* aven:
421
422  + (Microsoft Windows version): Fix error on startup in the pre-built version
423    of 1.2.39 and 1.2.40.  This is a recurrence of the same issue as affected
424    1.2.33 - this time I've patched out the unnecessary check in wxWidgets
425    which causes this problem so it shouldn't recur again.  Reported by
426    Brian Clipstone.
427
428  + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
429    as I don't have access to a Mac).  Hopefully fixed #101, reported by floho.
430
[d034033]431Changes in 1.2.40 (2019-07-04):
432
433* aven: Draw the measuring line ring with an even shape.  Previously the exact
434  shape of the ring varied slightly depending on the exact coordinates, which
435  could be visually distracting once you noticed it.
436
437* We were casting a function pointer with a bool return type to the same type
438  but with a void return type.  In practice this probably works fine on most
439  platforms, but it's undefined behaviour and also gives a compiler warning
440  with some compilers.
441
442* Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
443  installed.
444
[9fe70e44]445Changes in 1.2.39 (2019-06-29):
446
447* Support versions 5.x and 6.x of the PROJ library we use for handling
448  conversions between coordinate systems.  Reported by Bas Couwenberg
449  in #102, by Richard Knapp in #103 and by Martin Sluka in email.
450
451* (Unix and Mac OS versions): When checking if something is a file or if it is
452  a directory, we no longer treat a symlink as being neither, but instead
453  return an answer based on what the symlink points to.
454
455* aven:
456
457  + Improve handling of hidden splay ends.  Previously, hidden splay ends still
458    served as "targets" for snapping the mouse pointer to, and still got
459    crosses when crosses were enabled.  We don't have a handy flag for "this is
460    the outer end of a splay" and computing that on demand isn't so easy to do,
461    so for now we use the "anonymous station" flag so at least these cases now
462    behave properly for splays to anonymous stations (which is likely to be
463    what people with huge numbers of splays from disto-x, etc are using).  This
464    does mean that anonymous stations on continuation passages will incorrectly
465    also be off when splays are hidden, but that seems an OK trade-off for now
466    and a definite improvement over the previous situation.  The snapping of
467    the mouse pointer was reported by Frank Tully in #105.
468
469  + Fix typo in export UI (CVS should be CSV).
470
471* Documentation:
472
473  + Add CSV to documented list of survexport output formats.
474
475  + Fix *declination syntax synopsis - "auto" is a literal string, not a
476    placeholder.
477
478  + Update PROJ project name and website - the name is now "PROJ" (all caps and
479    no ".4" suffix) and the website is now: https://proj.org/
480
481* Install gtksourceview-3.0 language file so .svx files now get syntax
482  highlighting in gedit and other GtkSourceView-based editors.  Patch
483  from Philip Withnall.  Fixes #98.
484
485* (Microsoft Windows version): The Survex installer doesn't uninstall the old
486  version when you upgrade, but just overwrites it with the new version.  In
487  1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
488  an older version would still have cad3d.exe from that old version.  We now
489  remove any old cad3d.exe left over from a previous install in the same
490  location to avoid confusion.
491
492* Add a few more message translations.
493
494* Fix warnings when built with a C++11 compiler.
495
[66b555d]496Changes in 1.2.38 (2019-03-02):
497
498* cavern:
499
500  + Deprecate MILS as angular units.  Survex has long support MILS as an alias
501    for GRADS.  However, this seems to be a bogus definition of a "mil" which
502    is unique to Survex (except that Therion has since copied it) - there are
503    several different definitions of a "mil" but they vary from 6000 to 6400 in
504    a full circle, not 400.  Reported by Andy Edwards.
505
506  + Fix segfault for *include "".  This isn't useful, but shouldn't crash.  It
507    now reports "file not found" instead.
508
509  + Use isnan() to check for not-a-number.  This is cleaner, more robust and
510    more efficient than formatting the number as a string and checking for
511    "NaN" or "nan" in the result.
512
513* Avoid unused variable warning when compiling from source with modern ffmpeg.
514
515* Drop support for wxWidgets < 3.0.  3.0.0 was released over 5 years ago and
516  should be easily available everywhere by now.  I'm no longer easily able to
517  test with wxWidgets 2.8, and this allows a significant amount of cruft to be
518  removed.
519
520* (Linux version): survex.spec: Fedora have removed gcc from the default build
521  environment so need to explicitly list it in the BuildRequires tag.  See
522  https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
523  information.  Patch from James Begley.
524
[3147062]525Changes in 1.2.37 (2018-11-18):
526
527* aven:
528
529  + Add basic "Colour by Survey" feature.  The colours used aren't currently
530    controllable.
531
532  + Fix export of splays.  Patch from Thomas Holder.
533
534  + Fix KML export to avoid invalid geometry when a tube intersects itself.
535    Patch from Robert Jones.
536
537  + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
538    for now.  This is a workaround until wxWidgets OpenGL support is updated
539    to work under Wayland.  Reported by Philip Balister.
540
[0482978]541  + Fix warnings about using deprecated functions when building movie export
542    code using FFmpeg 4.0.
543
[3ed7da1]544* cavern:
[3147062]545
[3ed7da1]546  + Compass MAK files: Handle fixed point coordinates in feet - previously the
547    units were ignored and the coordinates assumed to be in metres.
[3147062]548
[3ed7da1]549  + Previously the first byte in a MAK file was ignored.  Typically MAK files
550    start with a comment, and since cavern currently ignores lines that start
551    with characters it doesn't understand the meaning of, this bug would often
552    go unnoticed.
[3147062]553
554* survexport:
555
556  + Fix exporting of passages, walls and cross-sections by running the code
557    aven uses to decide how much to rotate each cross-section.  Previously all
558    cross-sections were aligned West-East.  Reported by Robert Jones.
559
560  + Default to .pos output if the program name is 3dtopos, and install a second
561    copy (or hardlink under Unix) as 3dtopos.  This provides compatibility with
562    current releases of Tunnel.  Reported by Becka Lawson, Wookey and
563    Stephen Crabtree.
564
565* Fix some German translations.  Patch from Thomas Holder.
566
567* (MacOS X version): Fix aven-create-app to not delete converted icons.
568  Typo spotted by Robert Jones.
569
570* Improve documentation for *team.  Document the requirement to quote names
571  unless a person is identified by just one name.  Document that the roles are
572  optional, as that information may not have been recorded, and to align with
573  therion's team command.
574
[26ab0a7]575Changes in 1.2.36 (2018-07-18):
576
577* aven:
578
579  + Add support for exporting as a CSV (Comma-Separated Values) file.
580
581  + Support exporting KML with altitude mode "clamp to ground".  In this mode,
582    the altitude in the data is ignored and it's rendered on the surface of the
583    terrain.  This is useful if your KML viewer renders the terrain as opaque
584    so underground data isn't visible.  Rendering cave passages on the surface
585    isn't great, but is better than not being able to see them at all.  This
586    option may also be helpful if you want to see where to look on the surface
587    for new entrances.
588
589  + Highlight surveys with a white loop as the mouse is moved over them in
590    the survey tree.  This is akin to how we highlight a station with a
591    white ring, and allows restoring "double-click survey in tree to zoom"
592    which temporarily required a quadruple-click in 1.2.35.
593
594  + Only show checkboxes in the survey tree for surveys not stations.
595
596  + Fix wxWidgets assertion if the user tried to select additional surveys
597    to show via the right-click menu.
598
599  + Fix multiple survey filtering when both a parent and child survey are
600    selected.  In this case it makes most sense to show all child surveys of
601    the parent, but we actually showed a slightly arbitrary subset of the
602    child surveys of the parent.
603
604  + The checkbox area in the survey tree is now included in the area which
605    is considered by mouse-over updates such as highlighting the station or
606    survey.
607
608  + Fix display of double quotes in cavern log window (they were being replaced
609    with control character 0x16 due to a typo in the code).
610
611  + Add shortcuts to buttons in cavern log window.
612
613  + Eliminate use of gluErrorString() function which eliminates some
614    deprecation warnings when building on macOS.
615
616  + Reject multiple --survey command line options for now (only the last has
617    been used for a long time, but now we actually support multiple survey
618    filtering this matters more).
619
620* survexport:
621
622  + Report a useful error when trying to convert a .3d file without coordinate
623    system information to GPS.  Reported by Mark Shinwell.
624
625  + Handle multiple redundant --survey command line options correctly.
626
627* dump3d: Report station flag "WALL", which was added in 1.2.7.
628
629* Minor translation updates.
630
631* Update manual for Microsoft Windows changes.
632
633* tests/: Add test coverage for warnings about suspect readings
634
635* Fix warning when compiling with clang.
636
[facb636]637Changes in 1.2.35 (2018-07-03):
638
639* aven:
640
641  + Viewing can now be restricted to multiple surveys.  Use the right-button
642    menu on a survey in the survey tree and select "Show" to enable checkboxes
643    for that survey and all its siblings.  Only the selected surveys are shown
644    on screen, printed and exported.
645
646  + Don't open a survey when its name is double clicked.  This was happening
647    due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
648    However, reverting that change still seems to allow double-clicking to work
649    on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
650    survey.
651
652  + Pick initial survey scaling based on whichever of the window width or
653    height gives the smaller scale.  Previously we always used the window
654    width, which can result in parts of the cave being outside the initial
655    view.  Reported by Wookey.
656
657  + Drop ability to specify a PROJ string in the export dialog.  This was added
658    to allow exporting to formats such as GPX before we added support for
659    specifying the projection in .svx files, and that support is now mature.
660
661  + DXF export now uses 2 decimal places (was 6) for the bounding box, for
662    consistency with the precision used for coordinates.
663
664  + Fix handling of surface flag during export.  In formats which discriminate,
665    legs could previously have got assigned the wrong status.
666
667  + Fix bug which probably prevented aven starting when OpenGL double buffering
668    is unavailable.  This is unlikely to affect any common configurations.
669
670  + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
671    filenames.  Issue reported by Matic.
672
673  + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
674    Probably broken since 1.2.17.
675
676* survexport: New command-line export program which uses aven's export code.
677  Replaces 3dtopos, cad3d and findentrances, since it can do all that these
678  tools could do, plus much more.
679
680* Merge more Spanish i18n updates from Evaristo Quiroga.
681
682* Minor updates to various other translations.
683
684* img library:
685
686  + Now supports reading from and writing to an existing FILE*.
687
688  + Improve API documentation.
689
690* (Microsoft Windows version): Fix packaging to include wxWidgets translation
691  files like it was supposed to, which fixes a few missing translations.  This
692  was probably broken by changes in 1.2.8.  Reported by Evaristo Quiroga.
693
694* (Microsoft Windows version): Drop two options from explorer bindings.
695  "Convert to DXF" and "Convert for hand plotting" have both been supported via
696  aven for a while, and that's a more useful way to access them as you can
697  control what gets exported.
698
[5279c800]699Changes in 1.2.34 (2018-03-24):
700
701* aven:
702
703  + (Microsoft Windows version): Fix error on startup in the pre-built version
704    of 1.2.33.
705
706  + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
707
[f057bc1]708Changes in 1.2.33 (2018-03-22):
709
710* aven:
711
712  + Reliably disable scale bar in perspective view.  This is supposed to happen
713    (because the scale across the screen varies in perspective view) but
714    actually the scale bar stayed around until an update was forced for another
715    reason.  Spotted thanks to Pedro Silva Pinto.
716
717  + Make "no date"/"not in loop" colour grey.  The white was a bit bright and
718    made it harder to see the legs that had colours.  The grey now used is
719    within the brightness range of the other colours.  Fixes #94, reported by
720    Erin Lynch.
721
722  + Fix KML export - exporting both survey legs and station names resulted in a
723    malformed KML file.  This bug was introduced in 1.2.30 when support for
724    exporting passages and walls was added.  Reported by Erin Lynch in #90.
725
726  + Consistently use 2 decimal places for altitude in KML output.  Some places
727    used 8 decimal places which is appropriate for lat and long, but clearly
728    overkill for an altitude in metres and increases the file size
729    unnecessarily.
730
731  + Right-align bearing widget in print/export dialog.  The change to allow the
732    value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
733    left-aligned (due to incorrect wxWidgets documentation of the default style
734    for this control).
735
736  + (Unix version): Work around wxWidgets bug so that custom cursors work
737    under GTK3.
738
739  + (Unix version): Update GTK version reporting - report GTK3, and don't
740    bother to report subversions of GTK2 (it seems to be fairly arbitrary
741    which subversions wxWidgets defines constants for).
742
743  + Update code to work without warnings when using wxWidgets 3.1.0 (the
744    current development version).
745
746  + Make movie export code compatible with upcoming FFmpeg 3.5 release.
747    It should still work with the older versions that worked before this
748    change.  Reported by James Cowgill in https://bugs.debian.org/888334
749
750* cavern:
751
752  + Warn about 2 digit years.  We can't change the assumption that these are
753    19xx without risking breaking existing datasets, but the further we get
754    into this century, the more likely such an assumption is to catch someone
755    out.  The warning can easily be quashed by explicitly adding the assumed
756    "19".
757
758* The Spanish translation is now up to date once more, thanks to updates from
759  Evaristo Quiroga.
760
761* Merge French translation updates from Jean-Marc.
762
763* Fix transposed German Northing and Easting labels.  Fixes #95, reported by
764  milosch.
765
766* Fill in missing translations of "Easting", "Northing", "E" and "N" for
767  Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
768  translated messages.
769
770* Align .pos file headings better with columns of coordinates below for
771  Indonesian and Polish.
772
773* Fix handling of the message string "error" before messages loaded.  If
774  there's an error loading messages, we need this message to report it.
775  Reported by Martin Sluka.
776
777* Fix a few compiler warnings.
778
779* img library: Fix extracting leaf survey name for survey title.  When there
780  are three or more levels of survey, we were taking everything after the first
781  dot rather than everything after the last dot.
782
783* Fix problems with testsuite on macOS:
784
785  + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
786    - this test isn't meaningful unless the filing system is case-sensitive,
787    but happens to fail if it isn't.
788
789  + cavern.tst: Workaround limitations of Apple's sed.
790
791  + aven.tst: Fix not to hang on macOS.
792
793  + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
794
795* Clean up handling of support files in relocatable installs - this is now
796  detected at run time on macOS.
797
798* Split out macOS Aven.app creation into a make rule so it can be easily used
799  by the homebrew formula.
800
801* buildmacosx.sh:
802
803  + Fix when WX_CONFIG not specified - this was giving a confusing error like:
804    ./buildmacosx.sh: line 163: --cc: command not found
805
806  + Use wxWidgets 3.0.4.
807
808* Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
809  and we currently require 2.8 or newer.
810
[66576b6]811Changes in 1.2.32 (2017-07-08):
812
813* aven:
814
815  + Make splays on printouts a darker shade of grey.  Reported by Erin Lynch
816    and Anthony Day.
817
818  + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
819    POS), the value in the Z dimension was negated.  Bug introduced by fixes
820    for export of rotated plans and tilted elevations in 1.2.27.  Reported by
821    Erin Lynch in #89.
822
823  + Ignore viewing angles for export formats which work in 3D.  When the
824    rotation and tilt controls are hidden in the export dialog we were still
825    using their values to transform the data, so if you set them with for one
826    export format which support them, then switched to an export format which
827    doesn't, you'd get bogus coordinates in the exported file.  Bug probably
828    introduced in 1.2.27 by fixes for exports of rotated plans and tilted
829    elevations.
830
831  + Fix exporting to skencil and Survex .pos formats.  When aven's export to
832    .pos was added in 1.2.19, the ordering didn't match up and since then .pos
833    export has produced skencil files and vice versa.
834
835  + Don't leave terrain on if loading terrain data fails.  Previously if you
836    clicked the terrain icon (or via the menu) with no terrain loaded, but no
837    terrain got loaded (e.g. because the survey data lacks an explicit
838    coordinate system, or because the file failed to load, or because you
839    cancelled the dialog) then the terrain icon/menu item was still changed to
840    "on".
841
842  + Disable texturing while drawing terrain.  Previously the terrain got a bit
843    darker when "Textured Walls" were enabled.
844
845  + Force a refresh when "Textured Walls" are enabled or disabled.  Previously
846    the display wouldn't update right away.
847
848* Manual:
849
850  + Document how to specify fixed point altitude in feet.
851
852  + Explain why *fix warns about unused fixed points
853
854* Building from source now requires a compiler with decent support for C++11.
855  If you're using GCC, then GCC 4.7 should suffice.  This should not be an
856  onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
857  enough GCC.  If special options are needed, these should get probed for and
858  automatically.  Fixes building 1.2.31 with GCC < 6, reported by Wookey.
859
[28695f1]860Changes in 1.2.31 (2017-07-01):
[11c814b]861
862* aven:
863
864  + Use superscript 'g' symbol instead of word 'grads' in status bar.  This
865    conserves the limited space available, and we already do this in the
866    compass and clino indicators so it's more consistent too.
867
868  + Show one decimal place on measure line bearing.  Pointed out by Benedikt
869    Hallinger on the therion list, though I'm sure this has been asked for
870    before by others.
871
872  + Show gradient of the measuring line when both ends are stations.
873
874  + Allow selection of text in cavern log window.  Selection was disabled in
875    1.2.28 because it seemed you couldn't actually copy selected text to the
876    clipboard, but retesting this now actually works fine for me, both with
877    current git master with the change reverted, and with code just before the
878    original change.
879
[28695f1]880  + More robust parsing of cavern output (cleanly handle context highlighting
881    which extends beyond the end of the line).
[11c814b]882
883  + Allow showing duplicate legs as dashed lines or hiding them entirely,
884    with dashed now being the default.  Implemented by Patrick Warren.
885
886  + Also allow "Dashed" for splays and "Faded" for duplicate legs.
887
[28695f1]888  + Splay legs in surface data are also shown faded.
[11c814b]889
[28695f1]890  + Check environment variables VISUAL and EDITOR when looking for editor to
891    use when a warning or error is clicked on in the cavern log window.  The
892    specified editor may have a GUI or need to run in a terminal, so we have to
893    special-case each editor supported, and that means we can pass extra
894    options needed to position the cursor on the appropriate line/column.
895    Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
896    emacs, nano, jed, kate.  Suggested by Wookey.
[11c814b]897
898  + Fix handling of non-square terrain data files - the X and Y dimensions were
899    swapped.  Reported by detrito.
900
[28695f1]901  + Improve parsing of DEM data with .hdr file.  Use documented defaults for
902    more values, and where we only support a subset of values (or a particular
903    value) check for unsupported values in more cases.
904
905  + When colouring by depth, fix colouring and texturing of polygons which
906    cross depth bands.  The previous problems were most obvious with high
907    chambers and long legs down deep pitches, especially in for surveys without
908    much vertical range.
909
910  + Support for drawing blobs using point sprites was added in 1.2.28,
911    but caching that this worked wasn't hooked up properly so the test to
912    see if this worked would happen at the start of each run.  This is now
913    cached as intended which should reduce start up time a little when blobs
914    are drawn in this way.
915
916  + Fix drawing of crosses with lines.  This is a fall-back case which is
917    rarely used as most OpenGL setups will handle a better method, but it was
918    resulting in crosses with a four-pixel square in the centre - now the
919    centre should be a single pixel.
[11c814b]920
921* cavern:
922
[28695f1]923  + Allow *data with no arguments to reset the current style - useful for
924    entering passage data where there are side passages.
925
926  + Fix hang processing file without newline at end.  This bug was introduced
927    by changes in 1.2.28.  Reported by Mark Brown.
928
[11c814b]929  + (Mac OS X and Microsoft Windows versions): Build with newer version of
930    PROJ library which fixes buggy handling of *fix with lat-long coordinates.
[28695f1]931    Also add a testcase to the testsuite to alert users building for themselves
932    with an affected PROJ version on any platform.  Reported by Ross Davidson.
[11c814b]933
934  + Fix cavern to handle Compass .DAT with no survey team.  Previously this
935    resulted in the bogus error: Expecting numeric field, found "FROM"
936    Reported by Erin Lynch.
937
938  + Handle UTF-8 "BOM" at start of .svx files.  Unicode doesn't recommend its
939    use, but Microsoft stuff seems to like to create files with it in, and the
940    error cavern currently reports for such files is very confusing, so it
941    seems best to just handle it.  Reported by Rob Eavis.
942
943  + Change a couple of messages to use double quotes for consistency with all
944    other messages.
945
[28695f1]946* extend:
947
948  + Now runs a bit faster.
949
950  + Splays are now carried over the extended survey.  The current handling
951    is simplistic, but should do a good enough job to be more useful than
952    discarding splays.  The splays at each station are all rotated together
953    based on the bearing between the stations either side of the current one
954    along the first path extended through that station.  This nicely handles
955    dead ends and the situation at the top or bottom of a pitch, and should
956    tend to pick an angle close to the passage orientation along a traverse.
957    It's weakest at junctions.  Feedback (especially examples which could
958    be handled better) most welcome.
959
960* French translation is now up to date again, thanks to Jean-Marc.
961
962* Remove erroneous menu shortcut markers from Polish translations.
963
964* Fill in some missing translations in several languages by using message
965  translations from therion.
966
967* Add note to *fix documentation to clarify the coordinate order with *cs
968  long-lat.  Issue raised by Ross Davidson.
969
[11c814b]970* Fix errors in documentation of *units: "DEG" should be "DEGS", and
971  "MINUTES" has been supported for ages but wasn't documented.  Reported by
972  Footleg.
973
[28695f1]974* Fix a few typos in the documentation.
975
976* Fix compilation warning with recent GCC.
[11c814b]977
[56b37f3]978Changes in 1.2.30 (2016-10-03):
979
980* aven:
981
982  + (Microsoft Windows version): Fix crash when trying to print or export
983    (probably introduced in 1.2.28).  Reported by Brian Clipstone.
984
985  + Report error if terrain file contains no terrain data in area of survey.
986    Suggested by detrito.
987
988  + Errors when writing an export file were reported with the wrong filename
989    - the .3d file, not the filename we were trying to write to.
990
991  + Export to KML now supports exporting passages, walls and cross-sections.
992    Addresses the remainder of ticket #4.
993
994* Add man page for dump3d.
995
[d0418ac]996Changes in 1.2.29 (2016-09-27):
997
998* aven:
999
1000  + Fix SVG output with non-ASCII characters (the charset in the SVG file
1001    is now set to UTF-8 not ISO-8859-1).
1002
1003  + (Microsoft Windows version): Fix error dialog on startup in pre-built
[53c1e5d]1004    version.  Reported by Brian Clipstone.
[d0418ac]1005
1006* Manual: Add link to TerrainData wiki page.  Omission highlighted by Erin
1007  Lynch and "detrito".
1008
1009* Fix to build without FFmpeg/libav and with older versions, broken by changes
1010  in 1.2.28.  Reported by James Begley.
1011
[6897356]1012Changes in 1.2.28 (2016-09-24):
[0d8f67a]1013
1014* cavern:
1015
1016  + Show the contents of the line after error and warning messages while
1017    processing survey data, and indicate the region of the line in many cases
1018    in the same style that compilers such as GCC and clang use (using the
1019    column number we already have, plus new width information).  Based on a
1020    patch from Mateusz Golicz.
1021
1022  + Add column and width information for many more error and warning messages.
1023
1024  + Fix column for "Separator in survey name" warning.
1025
1026  + Improve warnings when using a backclino with range 0-180 degrees (reusing
1027    the same machinery we already have for a forward clino with range 0-180
1028    degrees).
[99b3298]1029
1030* aven:
1031
1032  + Include LRUD in printout/export of extended elevations, broken by
1033    improvements to export of tilted elevations in 1.2.27.  Reported by Anthony
1034    Day.
1035
1036  + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
1037    usefully.  Reported by Anthony Day.
1038
1039  + Remember scale from previous print or export operation in the same run of
1040    aven.  Suggested by Stuart Bennett.
1041
[0d8f67a]1042  + Convert range indication below shown line to a highlight on that region
1043    of the line in cavern log window.
1044
[99b3298]1045  + Fix colouring of error/warning without column in cavern log window.
1046
1047  + Fix click on error/warning without column in cavern log window.
1048
[6897356]1049  + Fix highlight of translations of "error" or "warning" containing non-ASCII
1050    characters.  This fix for this only works with a Unicode build of
1051    wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
1052    shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
1053    Reported by Mateusz Golicz.
1054
[0d8f67a]1055  + Disable selection of text in cavern log window - you can't currently copy
1056    it to the clipboard, so until that's implemented it seems better to disable
1057    the ability to select it.  Reported by Wookey.
1058
[99b3298]1059  + Avoid special "1000" scale entry when exporting.
1060
1061  + Show 1 page when "One Page" selected.
1062
1063  + Reload processed data when restricting view.  Fixes failure when
1064    restricting view on data just processed via aven.  Spotted by Andrew
1065    Atkinson and myself.
1066
1067  + Don't hide blobs and crosses behind terrain.  Reported by Jenny Black.
1068
1069  + Fix rendering of crosses using point sprites.  The texture being used was
1070    misaligned relative to the image used for the visual fidelity check, so the
1071    check always failed and point sprites would never be used.  Where point
1072    sprites are supported, they're probably the fastest option - on my netbook
1073    this change improves FPS by ~6 fold when displaying crosses for a large
1074    survey.
1075
1076  + Support drawing blobs using point sprites.  About 5 times faster than using
1077    lines on my netbook.
1078
1079  + Recheck how best to draw crosses and blobs on the first run after Survex
1080    is upgraded (or downgraded) as the rendering code may have changed (we
1081    already recheck when the OpenGL hardware or driver changes).
1082
[6897356]1083  + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
1084    MPEG4 produces smaller output of higher quality, and should be widely
1085    supported these days.  And I can't get the MPEG1 output to work without
1086    buffer underflows, resulting in a file which doesn't play without
1087    glitches.
1088
1089  + Add OGG video to the list of formats - it's more compact than the others
1090    we currently list, though slower to write.
1091
1092  + Fix export to movie formats for which libav/FFmpeg needs to seek the file
1093    being written.  This was broken by changes in 1.2.27.
1094
1095  + Overhaul movie export for the current FFmpeg API, fixing deprecation
1096    warnings when building against a recent version.
1097
[99b3298]1098  + (Microsoft Windows version): Fix corrupted exported movie files.  1.2.27
1099    changed the movie export code to allow writing to files with non-ASCII
1100    characters in the names, but the new code failed to open the file in binary
1101    mode, leading to corrupt output.  Fixes #81, reported by Erin Lynch.
1102
[f55cbeb]1103  * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
1104    movie export.
1105
1106  * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
1107    export.
1108
[99b3298]1109* Fix to build without FFmpeg/libav, broken by changes in 1.2.27.  Reported by
1110  James Begley.
1111
[0d8f67a]1112* The Polish translation is now very close to being complete, thanks to a
1113  substantial update from Mateusz Golicz.
1114
[99b3298]1115* Merge catalan translation updates from Adolfo Jayme.
1116
[7333c2c]1117* (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
1118  messages get used automatically.
1119
1120* cavern.tst: Remove random : from after ] - dash ignores the extra character,
1121  but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
1122
[0d8f67a]1123* cavern.tst: Add expected output for more testcases.
1124
1125* Remove unwanted execute bit from some testcase data.
1126
1127* Use https for more URLs which support it.
1128
[690fdab]1129Changes in 1.2.27 (2016-06-06):
[dfe8d05]1130
1131* aven:
1132
1133  + Right click on a survey in the survey tree now gives a pop-up menu
1134    with "Hide others", which restricts the view to just that survey
1135    and any subsurveys.  Right click on the root of the survey tree
1136    gives a menu with "Show all" to undo any restriction in effect.
1137    (Currently these are implemented by reloading the file and using
1138    the same machinery as the --survey= command line option, but that will
1139    probably change in the future).
1140
[690fdab]1141  + If there's a sub-survey restriction (from the --survey= command line
1142    option or the new UI described above) it is now shown in brackets after
1143    the survey tree root.
[dfe8d05]1144
[690fdab]1145  + When reloading a survey, preserve the current view position (previously
1146    the view was recentred).
[dfe8d05]1147
1148  + When reloading a survey, actually preserve the current scale factor
1149    (this was meant to happen, but the adjustment was applied in the
1150    wrong direction).
1151
1152  + New "File->Extended Elevation..." menu item provides a way to generate
1153    extended elevations for simple cases without having to use the command
1154    line.  Suggested by Fleur Loveridge.
1155
[690fdab]1156  + Don't process key presses if accompanied by an unexpected modifier key.
1157    In particular, this means that aven no longer interferes with Alt+<function
1158    key> (which is typically handled by the desktop) and Alt+<letter> (which is
1159    typically a menu short cut).  Reported by Владимир Георгиев.
[dfe8d05]1160
1161  + Reduce file loading time by ~5%.  The station name compare function was
1162    something of a hot spot, and optimising it yielded a nice improvement.
1163
[690fdab]1164  + Allow splay legs to be disabled in when printing and exporting.  Mostly
1165    addresses #60.
1166
1167  + SVG export now shows splay legs thinner and in grey.  See #60.
1168
1169  + Fix export of rotated plans and tilted elevations - previously plans were
1170    always aligned with North up, and elevations which weren't exactly side on
1171    were exported as plans.  Reported by Stuart Bennett.
1172
1173  + Fix offset bounding box for exported elevations.
1174
1175  + In print/export dialog the bearing value now wraps if you scroll up past
1176    360 or down past 0.
1177
1178  + Fix greying out of LRUD-based controls in the print/export dialog when the
1179    view is tilted (i.e. not plan or elevation).  This stopped working in
1180    1.2.18 when the pan and tilt spin controls were changed from integer- to
1181    real-valued ones.
[dfe8d05]1182
1183  + Printouts now show LRUD as pale grey arrows from the station they are
1184    measured from.  Based on patch from Michael Sargent.  Closes #65.
1185
[690fdab]1186  + Take LRUD into account for printout size.  Fixes #72, reported by Erin
1187    Lynch.
[dfe8d05]1188
[690fdab]1189  + Update movie export code to work with latest version of FFmpeg.
1190
1191  + Make "Show Log" a toggle, so you can click on the button to take a look at
1192    the log, and a second click returns you to the survey view.
1193
1194  + (Microsoft Windows version): Open the font file in binary mode - it looks
1195    like we were lucky and the font file (or at least its current version)
1196    would have loaded OK in text mode despite being binary data.
1197
1198  + (Microsoft Windows version): Exporting to files with non-ASCII filenames
1199    should now work.
[dfe8d05]1200
1201* cavern:
1202
1203  + Allow tape or backtape to be omitted.  Reported by Erin Lynch.
1204
1205  + Grid convergence is now corrected for when using automatically
1206    calculated declinations (*declination auto <X> <Y> <Z>).  Requested
1207    by Mateusz Golicz on the mailing list.
1208
1209  + Clear any cached calculated declination upon another *declination auto
1210    with different coordinates.  Previously if the date stayed the same,
1211    a previously cached declination for the old coordinates was used.
1212
[3ca8ad2]1213  + Fix check for end of version number array in *require.  We would check up
[dfe8d05]1214    to 12 version components, the last 9 being bogus.  In practice, *require is
1215    only likely to be used with up to three components, so this wouldn't be an
1216    issue.
1217
1218  + *begin with an invalid prefix could cause a crash in some cases.  Fixed
1219    by patch from Colin Watson.
1220
[690fdab]1221  + Report column locations for errors to do with readings.
1222
[dfe8d05]1223* Merge translation updates from Jean-Marc.
1224
1225* img library: Better document which members can be set when writing.
1226  Highlighted by email query about use of img API from Владимир Георгиев.
1227
[690fdab]1228* Document how *declination interacts with *calibrate declination if both are
1229  used in the same dataset.
1230
[dfe8d05]1231* doc/3dformat.htm: Update details of how changes to the current label buffer
1232  are encoded to reflect changes in v8.  Reported by Angus Sawyer.
1233
1234* Use docbook2man instead of docbook-to-man to generated Unix man pages
1235  from SGML source.  The latter seems to be no longer actively maintained, and
1236  docbook2man now does a similarly good job.
1237
1238* Use https for survex.com links, and for other sites which support it.
1239
[cd746b9]1240Changes in 1.2.26 (2016-01-07):
1241
1242* aven:
1243
1244  + (Microsoft Windows version): Fix to be able to process .svx files with
1245    cavern again.
1246
[8ee50db]1247* (Microsoft Windows version): Simplify upgrading process with innosetup
1248  installer - if Survex is already installed, we now just install to the same
1249  location and use the same start menu folder.
1250
1251* (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
1252  Fixes #79, reported by James Begley.
1253
1254* (Linux version): survex.spec: Fix to work with RPM 4.13.  Fixes #79, reported
1255  by James Begley.
1256
[cd5cd8f]1257Changes in 1.2.25 (2016-01-05):
[4e92bec]1258
[cd5cd8f]1259* aven:
[4e92bec]1260
[cd5cd8f]1261  + Drop broken code which attempts to fix 2D pitches.  Fixes #73, reported by
1262    Erin Lynch.  #76 tracks the issue the removed code was trying (but failing)
1263    to address.
[4e92bec]1264
[cd5cd8f]1265  + When animating, don't try to update station info based on mouse movement
1266    over the survey tree.
[4e92bec]1267
[cd5cd8f]1268  + Further improve code to handle cavern subprocess in aven.
[4e92bec]1269
[cd5cd8f]1270  + Fix jump to error for filenames containing colons when the error location
1271    doesn't have a column number.  Bug noted by Jenny Black.
[4e92bec]1272
[cd5cd8f]1273  + If we encounter bad UTF-8 in cavern output, replace it with a red and white
1274    ? in a diamond (previously we gave up showing output at the first bad
1275    sequence).  This can happen if you process a .svx file which isn't UTF-8
1276    encoded.
[4e92bec]1277
[cd5cd8f]1278  + (Unix version): Don't try to set the terminal window title when opening an
1279    editor from the cavern log window - gnome-terminal no longer supports this,
1280    and there doesn't seem to be a portable option for specifying the title for
1281    terminals which do still support this.
[4e92bec]1282
[cd5cd8f]1283  + (Microsoft Windows version): Also quote for cmd.exe so that paths with
1284    spaces in work reliably.  Reported by Marco Cotto.
[4e92bec]1285
[cd5cd8f]1286* cavern:
[4e92bec]1287
[cd5cd8f]1288  + Improve error for mismatched fore/back-sight plumbs, reported by Andy
1289    Edwards (see #78).
[4e92bec]1290
[cd5cd8f]1291  + Fix to use correct sd for backcompass.  We were using zero instead, the
1292    most obvious effect of which was that the threshold for warning about
1293    differing COMPASS and BACKCOMPASS was about 71% of what it should have
1294    been, so we were warning in more cases than we should have been.
[4e92bec]1295
[cd5cd8f]1296  + Implement support for specifying a length on backsights - if you're using
1297    something like a disto-x, you'll get a distance reading for the backsight
1298    too.  Fixes #71, reported by Erin Lynch.
[4e92bec]1299
[cd5cd8f]1300  + Make line counting more robust to mixed line ends.  Noticed in example file
1301    from Pete Smart (see #69).
[4e92bec]1302
[cd5cd8f]1303* extend: New --show-breaks option which adds a leg flagged as surface survey
1304  between each points at which a loop has been broken.  Suggested by Jenny
1305  Black.
[4e92bec]1306
[cd5cd8f]1307* (Unix version): Update filetype metadata to work with modern desktops.
[4e92bec]1308
[cd5cd8f]1309* Fix incorrect reporting of errors reading and writing processed survey data.
1310  Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
1311  IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
1312  external programs using the img library, only Survex).  Reported by Jenny
1313  Black.
[4e92bec]1314
[cd5cd8f]1315* Add missing options to extend man page and --help output.  Noted by Jenny
1316  Black.
[4e92bec]1317
[cd5cd8f]1318* Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
[4e92bec]1319
[cd5cd8f]1320* Fix broken SGML markup in manual.
[4e92bec]1321
[cd5cd8f]1322* Fix typo in manual reported by Jenny Black.
[4e92bec]1323
[cd5cd8f]1324* Update vim syntax file for newer commands, etc.
[4e92bec]1325
[cd5cd8f]1326* Minor translation updates.  Thanks to Piotr Strębski and Jean-Marc.
[4e92bec]1327
[cd5cd8f]1328* Fix to compile with FFmpeg 2.9.  Reported by Andreas Cadhalpun in
1329  https://bugs.debian.org/803863
[4e92bec]1330
[cd5cd8f]1331* Stop maintaining ChangeLog files.  They make merging patches harder, and stop
1332  'git cherry-pick' from working as it should.  The git repo history should be
1333  sufficient for complying with GPLv2 2(a).
[4e92bec]1334
[cd5cd8f]1335* (Microsoft Windows version): The installer requires admin privileges on Vista
1336  and later and OS versions older than Vista are past end of life, so drop code
1337  which tries to set up the registry differently depending if we have admin
1338  privileges or not.
[4e92bec]1339
[52dad0e]1340Changes in 1.2.24 (2015-09-23):
1341
1342* aven:
1343
1344  + (Microsoft Windows version): Fix the cavern log window.  Reported by Brian
1345    Clipstone.
1346
1347  + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
1348    Reported by Jenny Black.
1349
1350  + If wx was built with thread support, aven now runs cavern from a separate
1351    thread, which works much better under wxMSW (where we can't use select),
1352    and also seems a bit smoother on Linux.
1353
1354  + Fix handling of encoding of filenames when the operating system has no
1355    locale installed corresponding to the language selected for Survex's
1356    messages.
1357
1358  + Undo accidentally committed debugging code which was sending message to
1359    the terminal in 1.2.23.
1360
1361* (Linux version): configure now looks first for wx-config-3.0, which Fedora's
1362  wx3 packages have.  Reported by James Begley.
1363
1364* Indonesian translation fully up to date again.
1365
1366* Manual: Document anonymous stations, based on the text from NEWS.  Reported
1367  by Wookey.
1368
[1ff33eb]1369Changes in 1.2.23 (2015-09-06):
[1ed104f]1370
1371* aven:
1372
1373  + Updating the cavern log window is now much smoother, especially on slower
1374    machines.
1375
1376  + Show "busy" mouse cursor while processing survey data.
1377
1378  + Fix an assertion if you try to start processing a survex file while one is
1379    already being processed.
1380
1381  + Processing a .svx file with an error now still adds it to the file history.
1382    Reported by Martin Green.
1383
[d56a2d4]1384  + Fix the orientation of the starting end of tubes.
1385
1386* cavern:
1387
1388  + New *ref command to allow specifying an external reference (e.g. where to
1389    find the original survey notes).
1390
1391  + Drop support for showing percentage progress in cavern.  It's confusing in
1392    a multiple-file dataset as it shows progress in the current file so jumps
1393    around.  It also slows down processing, and on a slow machine you'd don't
1394    want that, while on a fast machine processing isn't slow enough for the
1395    progress display to be useful.
[1ed104f]1396
1397* French translation is now completely up to date, thanks to Michel Bovey.
1398
[d56a2d4]1399* Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
1400  OS X so that things like "*cs EPSG:29903" work.  Reported by Graham Mullan.
1401
[1ed104f]1402* (Microsoft Windows version): Process survey data with aven rather than
1403  running cavern.
1404
[53b6a5a]1405* (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
1406  releases have been built with 5.5.3) to see if that solves Ray Duffy's
1407  reported issue with not having file associations for .svx files created.
1408
[7f7dbd5]1409Changes in 1.2.22 (2015-08-17):
[d225571]1410
1411* aven:
1412
1413  + Ensure that the window has a depth buffer.  Whether it does by default
1414    seems to vary depending on OS and maybe graphics card.  Fixes #55 (terrain
1415    is no longer visible through itself), and also the rendering of passage
1416    tubes.  Thanks to Martin Green for pointing me in the right direction for
1417    finding this fix.
1418
1419* cavern:
1420
1421  + Fix *declination with an angle to actually work.
1422
1423  + Fix assertion if we try to identify a hanging survey by an anonymous
1424    station.
1425
[7f7dbd5]1426  + Improve errors for invalid survey names in *begin, *end, *equate and
1427    *export.
1428
[2d865b7]1429Changes in 1.2.21 (2015-07-28):
[31e9b72]1430
[03c259e]1431* aven:
1432
[2d865b7]1433  + Fix exporting to KML and other text-based formats to always use "." for the
1434    decimal separator - previously "," would be used when the user's locale
1435    specified this for the decimal separator.  Reported by Jan Schorn.
1436
[22f17f1]1437  + Implement exporting of survey legs in KML format.
1438
[03c259e]1439  + Put "paddle" placemarker icons on stations in exported KML files, using the
1440    same colour coding for entrances, fixed points and exported points as aven
1441    does.
1442
[2d865b7]1443  + Remove the "Coordinate projection" field from the print dialog, as it isn't
1444    relevant there.  Reported by Wookey.
1445
1446  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1447    been too small).  Reported by Wookey.
1448
1449  + Don't rescale if the same file is reloaded, but adjust the volume diameter
1450    as appropriate.
1451
[03c259e]1452  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1453    values on Windows.
1454
1455* cavern:
1456
[22f17f1]1457  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1458    radians, but we were passing degrees, which would generally cause the
1459    conversion to the output coordinate system to fail.  Reported by Wookey.
1460
[2d865b7]1461  + Fix *fix with standard deviations when *cs is in use, give an error for use
1462    of *fix with standard deviations before *cs.
1463
1464  + Add new *declination command with support for setting the declination
1465    automatically from the IGRF model based on the survey date.  Thanks to the
1466    Therion developers for the IGRF support code, which we're reusing.
[1687a13]1467    Fixes #54, reported by Wookey.
1468
1469  + Allow the units for the zero error to be specified, making it easier to
1470    specify calibration with a scale if you measure the zero error externally
1471    (rather than using the instrument itself).  Fixes #61, reported by Andrew
1472    Atkinson.
[2d865b7]1473
1474  + Report the error from PROJ when coordinate conversion fails as part of the
1475    actual error rather than on a separate line.
[22f17f1]1476
[03c259e]1477  + Fix use after free after *solve.  This only occurs if a leg between the two
1478    exact same stations appears right before and right after the *solve, which
1479    is unlikely in real data, but the testsuite has an instance of this.  This
1480    was introduced by the repeat leg averaging added in 1.2.17.
1481
1482  + Fix small memory leak when solving network.  This doesn't really matter
1483    when solving at the end of processing as cavern will exit after that, but
1484    if *solve is used we continue processing after solving.
1485
1486* Remove compatibility handling for specifying a country variant of a language
1487  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1488  changed to the standard "en_US" way back in 2001.  This code was mangling
1489  character sets with a "-" in, and is no longer useful.
1490
1491* Ignore any "@<something>" modifier in the language code.
1492
[2d865b7]1493* Improve documentation of magnetic declination handling, and cover the new
1494  "*DECLINATION" command.
1495
[ab3b4a9]1496* Document aven's command line options in the manual and its man page.
1497  Reported by Jenny Black.
1498
1499* Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1500  documentation.
1501
[22f17f1]1502* Remove references to SpeleoGen from the documentation - it hasn't been
1503  updated for many years, and can't read recent versions of the .3d format.
1504
1505* Strip documentation references to obsolete versions of MS Windows.
1506
[2d865b7]1507* doc/HACKING.htm: Update list of debian packages to install to build from git.
1508
[7027ea1]1509Changes in 1.2.20 (2015-06-26):
[0eaf4b1]1510
1511* aven:
1512
[6de8e942]1513  + When printing, use the top margin rather than the right margin to calculate
[31e9b72]1514    the height of the printable area.  In practice, the two values seem to be
1515    the same or very similar by default.
[0eaf4b1]1516
1517  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
1518    Maynard.
1519
1520  + Optimise the size of the about dialog images.
1521
[7027ea1]1522  + Add support for reading terrain data which isn't in a .zip file.
1523
1524  + Force a refresh after loading terrain data so that it gets displayed right
1525    away.
1526
1527  + Make checks for terrain data extensions in zip files case insensitive.
[6de8e942]1528
1529  + If reading terrain data fails, always report an error and never try to
1530    display it.
1531
1532* cavern: Allow clino readings in diving style data, suggested by Andrew
1533  Atkinson.  Currently these readings are ignored, but a future version will
1534  check that they're consistent with the angle given by the depth gauge and
1535  tape, and perform suitable averaging.
1536
[0eaf4b1]1537* Remove lingering traces of svxedit.
1538
1539* configure: Fix to allow compiling without libav/ffmpeg, as was possible
1540  before 1.2.19.
1541
1542* (Unix version): Install the filetype and aven application icons under
1543  /usr/share/icons/hicolor, which is where they're expected to be these days.
1544
1545* (Unix version): Add %f to Exec in survex-aven.desktop.
1546
1547* (Mac OS X version): Remove useless extra copy of about box images from OS X
1548  disk image.
1549
[6de8e942]1550* (Mac OS X version): Only ship one copy of each of the translations.
1551
[0eaf4b1]1552* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1553  libav features we don't use.
1554
1555* (Microsoft Windows version): Reduce the size of the aven binary by disabling
1556  a load of libav features we don't use.
1557
1558* (Microsoft Windows version): Update message files to fix a missing Chinese
1559  message in the installer.
1560
[1dc99d1]1561Changes in 1.2.19 (2015-06-18):
[f96ac93]1562
1563* aven:
1564
1565  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1566    the exported file in 1.2.18.
1567
[2dac61e1]1568  + Add exporting to Survex .pos format.
1569
[4b67f71]1570  + If the measuring line isn't currently active, pressing "Escape" will now
1571    exit full screen mode.
1572
1573  + (Mac OS X version): Change the shortcut for full screen mode to be the
1574    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1575    using since 1.2.7).
[2dac61e1]1576
[f96ac93]1577  + (Mac OS X version): When we centre the view on the station this can
1578    generate a mouse move event, so clear the variable which says we are
1579    dragging before we process a left click on a station.  This avoids random
1580    rotations of the survey when clicking on a station, reported in #47 by Hugh
[2dac61e1]1581    St. Lawrence.
[f96ac93]1582
1583  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1584    icons from being rescaled and looking fuzzy.
1585
1586  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1587    toolbar icons from being rescaled, but which requires an unreleased version
1588    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1589
1590  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1591    the top of the screen, since we can't seem to display the menu bar in this
1592    case like we do on other platforms.
1593
[739440f]1594  + (Mac OS X version): Enable aven's movie export feature.
1595
[2dac61e1]1596  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1597    support multi-monitor setups.
1598
[f96ac93]1599  + (Mac OS X version): Silence warning visible when aven is run from a
1600    terminal about a missing CFBundleTypeRole.
1601
[4b67f71]1602  + When reading terrain data from a .zip file, report an error if the .zip
1603    file is bad, or if it doesn't contain any terrain data we recognise.
1604
[f96ac93]1605  + Tweak error message in terrain reading code to distinguish two failure
1606    cases.
1607
[2dac61e1]1608  + Add viewing angles and scale to footer, and shorten some of the other items
1609    to make room for this extra information.  (Fixes ticket #52, reported by
1610    Erin Lynch)
1611
1612  + If the footer is wider than the printout width, scale down the font used
1613    so that it exactly fits; if the footer is narrower, than space out the
1614    items in in so it uses the full width.
[f96ac93]1615
1616  + If the saved size for aven's window exceeds the current display size
1617    (mostly likely because we're now plugged into a smaller monitor), then
1618    reduce the size of the window to fit the display.  If the saved size is <
1619    (480x320), increase it to at least that, as aven isn't usable in a smaller
1620    window.
1621
[2dac61e1]1622  + Remove crude bodge which tries to pick a nicer initial window size when
1623    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1624    with the same size window it had when it was closed, so the initial size is
1625    only relevant on the first ever run.
[f96ac93]1626
1627* Assorted translation updates.  Notably Indonesian is at 100% again.
1628
1629* Stop trying to catch and report signals.  The only real reason to do it is so
1630  we can say "Bug in program detected! Please report this to the authors"
1631  before we exit, but when the program crashes that's pretty obvious.  In aven
1632  we try to pop up a message box for this message, which may fail due to
1633  whatever caused the signal, while with the command line tools there's no
1634  great benefit over just letting the shell report the signal.
1635
[4b67f71]1636* Use pkg-config to probe for libav and proj, which sorts out the correct flags
1637  for building on OS X against a static install of libav.
1638
[3f02aa4]1639Changes in 1.2.18 (2015-06-03):
[2595419]1640
[4a8031f]1641* aven:
[a5670c7]1642
[4a8031f]1643  + Add support for reading terrain data (from a zip file containing either an
1644    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1645    rendering it as a transparent surface.
[a5670c7]1646
[4a8031f]1647  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1648    sanely want to perform from the menu.
[a5670c7]1649
[4a8031f]1650  + Create a "Colour by" submenu of the "View" menu to house the various
1651    colouring options.
[a5670c7]1652
[4a8031f]1653  + Add "Colour by Gradient" and "Colour by Length".
[a5670c7]1654
[4a8031f]1655  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1656    which seems more logical, and also allows the dialog to be closed by
1657    pressing "Escape".
[a5670c7]1658
[38e5701]1659  + Destroy any existing clipping region before we write the page footer.
1660    Hopefully solves ticket #52, reported by Erin Lynch.
1661
[4a8031f]1662  + Don't round bearing and tilt angles to integers when printing and
1663    exporting.
[a5670c7]1664
[38e5701]1665  + Add passage export for EPS format.  (Partly addresses ticket #4)
1666
1667  + Add JSON export.  This should be regarded as experimental, and the format
1668    is quite likely to change.
1669
[4a8031f]1670  + Pressing F6 now toggles the display of rendering stats, currently FPS
1671    (Frames Per Second) and the number of triangles in the terrain mesh.
[a5670c7]1672
[4a8031f]1673  + Add a menu item and toolbar button to show the cavern log window if the
1674    currently shown survey data was processed by aven.  Reported by Hugh St
1675    Lawrence in #47, and by Dave Clucas and others previously on the list.
1676
1677  + Add "Save Log" button to Aven's cavern log window.
1678
1679  + In cavern log window, highlight "error" markers in red and "warning"
1680    markers in orange.
1681
1682  + Rework code to read cavern's output.  In particular, we no longer mix
1683    buffered and non-buffered system calls.
1684
1685  + Aven's support for reading colours and font sizes for printouts from
1686    print.ini has never worked - the contents of the ini files are ignored due
1687    to a bug which has been there since the code was added in 2005 - but nobody
1688    has ever complained.  So just strip out that code entirely - we should
1689    support setting the colours and font sizes, but a GUI interface for setting
1690    them would be better.
1691
1692  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
1693    Gee.
1694
1695  + Take the width of the messages used above the compass and clino into
1696    account when calculating how much space to allow for them - now the labels
1697    won't overlap or be cut off in translations where they are long.
1698
1699  + (Mac OS X version): Attempt to address the size of the toolbar icons.
1700
1701* cavern:
[0476b10]1702
[38e5701]1703  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
1704    susscorfa).
1705
[4a8031f]1706  + Use the currently set units when outputting measurements in warnings,
[38e5701]1707    errors, and the stats at the end of the run.  Requested by Bill Gee.
[4a8031f]1708
1709  + Include column number when a *include file isn't found.
1710
1711  + Show 'error' in front of error messages, like we show 'warning' in front of
1712    warnings.  Fixes #48, reported by Wookey.
1713
1714  + Increase the threshold for warning that fore and back measurements differ
1715    from 2 SDs to 3 SDs.
1716
1717* findentrances: If the 3d file specifies the coordinate system, use it.
1718
1719* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1720  would be nice to have, svxedit doesn't really offer that, and it looks ugly
1721  in a modern desktop.
[a5670c7]1722
[dd65182]1723* If we run out of memory while reading a processed survey data file, include
1724  the filename in the error message.
1725
[4a8031f]1726* Many translation updates - notably Indonesian and Russian are now the two
1727  most complete translations.
[dd65182]1728
[4a8031f]1729* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
[dd65182]1730
[4a8031f]1731* Transliterate gradient and infinity symbols if the current character set
1732  lacks them.
[dd65182]1733
[4a8031f]1734* Add SVG version of .plt icon.
1735
1736* Manual:
1737
1738  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
1739    highlighting that the previous list was incomplete.
1740
1741  + Document averaging of a group of repeated readings.
[dd65182]1742
[4a8031f]1743  + Add a link to the sample data from the manual.
[dd65182]1744
[4a8031f]1745  + Remove references to contact addresses which are no longer there.  Remove
1746    offer to post people floppies, and references to a CD image which isn't
1747    available for download.
1748
1749* Remove non-breaking spaces from the diffpos and extend manual pages, as they
1750  actually make the output formatting worse (presumably these used to work
1751  around a since-fixed bug in one of the docbook processing tools).
[2595419]1752
[4a8031f]1753* doc/TODO.htm: Update.
[dd65182]1754
[3f02aa4]1755* Fix to compile without warnings with 'g++ --std=gnu++11'.
1756
[1646310]1757Changes in 1.2.17 (2015-02-24):
[a6064e2]1758
1759* MacOS X version:
1760
1761  + Update INSTALL file with current status.
1762
[e067870]1763  + Aven.app now has a custom icon.
[9e053fc]1764
[e067870]1765  + Add icons for all the filetypes supported.
1766
1767  + Add Finder actions for .svx, .3d, .plt and .pos files.
[9e053fc]1768
1769  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1770    currently do this for us.
1771
[a6064e2]1772  + aven: Fix short-cut for toggling Full Screen mode.
1773
1774  + aven: Make "About" menu item appear.
1775
[9e053fc]1776  + aven: Fix "Close" button in about dialog.
1777
1778  + aven: Make custom cursors black with a white outline to match the standard
1779    OS X cursor.
1780
[e067870]1781  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
1782    still doesn't really work like a standard app though - e.g. you can't load
1783    files from Finder (instead run svxedit.app and use File->Open), the font
1784    size of most menu items is wrong, the icon for the app is the wish icon
1785    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1786    probably more.  I'd probably recommend using another editor (OS X comes
1787    with TextEdit.app for example).
1788
1789  + The documentation is now in a "Docs" directory alongside the apps, rather
1790    than in the rather less obvious "share/doc/survex" directory.
1791
[a6064e2]1792  + Default to building for x86_64, since all modern Macs are 64 bit.
1793
[9e053fc]1794  + Disable use of liblzma when building wxWidgets for OS X, which was
1795    preventing the build from working on OS X 10.6.8.
1796
1797  + Download wx sources from SF via redirecting link.  Thanks to David A.
1798    Riggs.
1799
1800  + buildmacosx.sh: Handle the mount point for the disk image containing a
1801    space.
1802
[4baea3a]1803  + Link with a static build of PROJ for doing coordinate system conversions.
[9e053fc]1804
1805  + Build wx with --disable-webview to avoid a compilation failure on OS X
1806    10.10.1.
1807
1808  + Use wx-config --cc and --cxx to get the compilers to use for building
1809    everything else, as wx adds options to them which otherwise cause linking
1810    errors.
1811
[4baea3a]1812  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
1813    smaller download.  This means OS X 10.4 is required, but we probably
1814    already need at least 10.5 because that's the minimum version which the
1815    wxWidgets build supports by default.
1816
[e067870]1817  + Remove unused files and copies of files from the diskimage.
1818
[a6064e2]1819* cavern: If the same leg is repeated consecutively, average the readings and
1820  treat as a single leg.
1821
[9e053fc]1822* dump3d: Report SEPARATOR used by the file being read.
1823
1824* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
1825
1826* aven:
1827
1828  + Greatly reduce flicker when mouse is moved to the top of the screen in full
1829    screen mode and the menu bar reappears.
1830
1831  + For export formats where scaling is supporting, aven now actually uses the
1832    scale specified in the export dialog (previously it ignored this and used
1833    1:500).
1834
1835  + Reimplement animation so that it's based on angular change per unit of
1836    elapsed time, rather than averaging the time take for the last two scene
1837    redraws.  This gives smoother animation in the face of variable load and
1838    scene redraw time, and should be more consistent between platforms.
1839
1840  + Switching to a point of the compass during auto-rotation now jumps straight
1841    there rather than the two animations fighting.
1842
1843  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
1844    fast.
1845
1846  + Disable stepping the rotation angle when animating (previously we only did
1847    when rotating).
1848
[1646310]1849  + Speed up start-up a bit - rather than loading icons from individual PNG
1850    files on disk, compile them into the aven binary.
1851
1852* (Unix version): Add "MimeType" field to desktop files so that file
1853  associations work out of the box with modern desktop environments.
1854
1855* Add start of Hungarian translation from Imre Balogh.
1856
1857* Merge in many updates to the Russian translation from "vsuhachev".
1858
1859* Assorted minor updates to other translations.
1860
1861* Create scalable (SVG) versions of file type icons.
[e067870]1862
[a6064e2]1863* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
1864  we're using git.
1865
[1646310]1866* tests/: Improve test coverage in a few places:
1867
1868  + Extend tests of fore and back sights to test calibration of the back
1869    compass.
1870
1871  + Test "Can't calibrate angular and length quantities together" error.
1872
1873  + Check that "*set names ." works when "." is also the decimal point.
[a6064e2]1874
[03d0e8b]1875Changes in 1.2.16 (2014-10-17):
[9aa10ad]1876
1877* aven: Add KML export (stations only currently).
1878
[f480117d]1879* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
1880
[9aa10ad]1881* aven: Fix corrupted names in exported files.
1882
1883* aven: Fix error log window under wxWidgets >= 2.9 to include the system
1884  information before the first log message like it does under wxWidgets 2.8.
1885
1886* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
1887
1888* tests/: Improve test coverage.
1889
[7bd113b]1890* Translation updates for many languages, plus the start of translations to
1891  Greek and Polish.
[9aa10ad]1892
1893* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
1894  by Martin Sluka.
1895
1896* Fix warnings when compiling with clang (which is the default compiler on
1897  Mac OS X).  Reported by Martin Sluka.
1898
[44f51ca]1899Changes in 1.2.15 (2014-08-14):
1900
1901* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
1902  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
1903  means that we now support all the coordinates systems which Therion does,
1904  except for a few which don't have X=East and Y=North.  The documentation
1905  for *cs has also been improved.
1906
1907* aven: We no longer persist full screen mode between runs - it's not a
1908  standard behaviour of desktop programs, and it's too easy to go into full
1909  screen mode from the menu and then not be able to get out again because you
1910  don't know the required key shortcut. (ticket#39)
1911
1912* aven: When in full screen mode, moving the mouse to the top of the screen now
1913  makes the menu bar appear.  This provides a non-shortcut way out of full
1914  screen mode, as well as making it easier to perform other operations while in
1915  full screen mode.  The current implementation gives an annoyingly flickery
1916  transition, but hopefully we can improve this in future. (ticket#39)
1917
1918* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
1919  development), we now call EnableFullScreenView() which improves the full
1920  screen mode experience on OS X 10.7 and later.
1921
1922* img library: Improve documentation for img_ERROR_INFO.
1923
1924* tests/: Ship some missing .out files and compare.tst.
1925
1926* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
1927  testcase, and extend it to cover a variant of the situation reported as a bug
1928  in therion by Bill Gee to the therion list.
1929
1930* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
1931  for the survex package and on tk for the svxedit package.
1932
[6a87cce]1933Changes in 1.2.14 (2014-07-05):
[5c676e2]1934
[1efeb6d]1935* img library: Add ability to store a PROJ4 string describing the coordinate
1936  system in use in 3d v8 files.
1937
1938* aven: If the 3d file specifies a coordinate system, then use it for exporting
1939  to formats which need to know (currently GPX).  If the input file doesn't
[6a87cce]1940  specify the coordinate system, allow the user to enter a PROJ4 string in the
1941  export dialog.
[1efeb6d]1942
[ea59b58]1943* aven: You can now quickly zoom to a particular area by holding down the
1944  "Shift" key and dragging with the left mouse button to create a rectangular
1945  "rubber band box" around the area you wish to zoom to.  If you release the
1946  "Shift" key while still dragging, the box is centred on the start point
1947  rather than having one corner there.
1948
[26e7fa4]1949* aven: Fix exporting of passage tubes in elevations and extended elevations
1950  - previously up and down were getting drawn across the page!
1951
[5c676e2]1952* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1953  1.2.13.  (Reported by Brian Clipstone)
1954
[515b83e]1955* aven: Fix the conditions on which the menu item "Cancel measuring line" is
1956  enabled - previously it was hard to actually cancel it via the menu.
1957  Reported by Hugh St Lawrence.
1958
[5c676e2]1959* aven: Fix wx assertion failures when showing hit test debug view on platforms
1960  such as 64-bit Linux.
1961
[2c5ec88]1962* aven: When viewing from above, show "Plan" above the "clino" which indicates
1963  the tilt angle (instead of "Elevation -90°").
1964
[5c676e2]1965* aven: The extended font data now loads faster, and also uses less memory on
1966  64-bit platforms.
1967
[ea59b58]1968* aven: Dragging the vertical divider between the side panel and the 3D view
1969  now only updates when you finish the drag, as redrawing continuously just
1970  looks clunky except on an ultra-fast machine.
1971
[2c5ec88]1972* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
1973  the space available in the aven UI.
1974
[1efeb6d]1975* cavern: Add a *cs command to allow setting the coordinate system for *fix
1976  commands, and the coordinate system used for processed survey data.  The
1977  latter is now stored in 3d v8 format files.
[ea59b58]1978
[515b83e]1979* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
1980  and handle it in the same way as the "DUPLICATE" flag in .svx files.
1981
[6a87cce]1982* cavern: If there's more than one *fix command with coordinates, still
1983  actually fix the second and subsequent ones, to avoid triggering bogus errors
1984  about unconnected surveys.
1985
1986* cavern: If there's more than one *fix command with coordinates, report the
1987  station name of the previous one, plus the file and line number where it was.
1988
[67a0fc6]1989* cavern: Fix handling of the rather contrived case of *fix with no coordinates
1990  followed by *solve and then another *fix with no coordinates not to access
1991  freed memory.
1992
[1efeb6d]1993* dump3d: Report any specified coordinate system.
1994
1995* doc/3dformat.htm: Update to document how the coordinate system is stored.
1996
[2c5ec88]1997* (Microsoft Windows version): Include dump3d in the installer.
1998
[5c676e2]1999* Fix a compiler warning.
2000
2001* Improve test coverage.
2002
[0d365be]2003Changes in 1.2.13 (2014-05-15):
[acbb5b1]2004
[8ccd1d8]2005* aven: Fix --print option to wait for printing to happen before exiting
2006  (previously it would exit right after opening the print dialog, so you
2007  couldn't actually print anything out using it).
2008
[acbb5b1]2009* aven: Increase the threshold for how close the pointer needs to be to a
2010  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
2011  Hugh St Lawrence.
2012
[0d365be]2013* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]2014  if increasing the minimum pointer to station threshold helps Hugh's problems
2015  with using aven on a touch screen device.
2016
[acbb5b1]2017* aven: The measuring line was unable to see stations which had just been
2018  revealed by toggling surface or underground legs on - this is now fixed.
2019
2020* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
2021  many entries are in each box (toggled by F3).
2022
2023* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
2024  off and back on.
2025
2026* aven: Create the empty hit-test grid data structure lazily, to reduce start
2027  up time a little.
2028
2029* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
2030  and *end commands to instead talk about "survey names".
2031
2032* cavern: For ages cavern has warned if you reentered a survey, but this
2033  warning was suppressed if it occurred at the same line of the same file as
2034  the survey was first entered, but this can only happen if you include the
2035  same survey file more than once, which isn't a sensible thing to do for a
2036  file with actual survey data in (you might reasonably do it to set up survey
2037  grade details or something like that).  The warning is now given in this
2038  situation too.
2039
2040* cavern: After 5 warnings about reentering a survey we give up warning about
2041  it, but we used to keep reporting where the survey was originally entered -
2042  this secondary diagnostic message is now silenced when the main message is.
2043
2044* (Microsoft Windows version): Compile C code with optimisation on.
2045
2046* Add the start of a Russian translation, with messages take from therion.
2047
2048* Minor translation updates to French.
2049
2050* Fix compiler warning from GCC.
2051
2052* Testsuite improvements:
2053
2054  + Test that "..." anon station works.
2055
2056  + cavern.tst: Check number of errors returned by all testcases which should
2057    fail and give an error count.
2058
2059  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
2060
[ad727d8]2061Changes in 1.2.12 (2014-04-14):
[46d12e9]2062
[63e8642]2063* aven: Fix measuring line to show change in altitude rather than altitude
2064  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
2065  Clipstone.
[46d12e9]2066
[ad727d8]2067* aven: Fix printing when built with wxWidgets 3.0.
2068
2069* aven: Several visual improvements to printouts:
2070
2071  + Move the numbers below the scale bar down a little so that they don't
2072    overlap the scale bar ticks.
2073
2074  + Set the clipping region after we draw the page border and info box to avoid
2075    clipping the border in print preview.
2076
2077  + Tidy up the appearance of the compass and elevation arrow.
2078
[63e8642]2079* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
2080  <http://bugs.debian.org/739332>.
[46d12e9]2081
[63e8642]2082* aven: Fix to build with older libav where avcodec_free_frame() isn't
2083  available.
[46d12e9]2084
[ad727d8]2085* (Linux version) survex.spec: Update spec file used for building RPM packages.
2086
2087* (Unix version): Add "Keywords:" entry to .desktop files.
2088
2089* (Unix version): Enable large file support, mostly to support filing systems
2090  which return 64 bit inode values, such as CIFS mounts.
2091
[63e8642]2092* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
2093  rather than any character which is a letter in the current locale.
[46d12e9]2094
[63e8642]2095* Various translation updates.
[46d12e9]2096
[aac3336]2097Changes in 1.2.11 (2014-01-28):
[fb941bfd]2098
2099* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
2100  Reported by Kevin Dixon.
2101
[aac3336]2102* aven: Embed the font data for the first 256 Unicode characters for use in the
2103  survey pane into the compiled aven binary to reduce start up overhead.  Any
2104  additional characters needed are loaded from a data file only if/when a
2105  character >= U+100 is actually needed (as before).
2106
[ad3017d]2107* aven: Fix display of Unicode characters above 256 when there's a character
2108  <= 256 earlier in the same string.
2109
[77bdacf]2110* aven: Use the actual width of Unicode characters above 256 rather than
2111  assuming they are 16 pixels wide.
[ad3017d]2112
2113* aven: If full screen, don't show the side panel when a new file is opened
2114  (e.g. via Ctrl+O).
2115
2116* aven: Don't give an assertion failure when showing passages for a cave with
2117  no vertical extent.  Reported by Jonny Prouty.
2118
2119* aven: Change terminology in print dialog - say "legend" instead of "info
2120  box".
2121
2122* aven: Add option to show the tilt angle as a percentage gradient.
2123
2124* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
2125  indicators.
2126
2127* aven: All length units are now translatable.
2128
[fb941bfd]2129* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
2130  will reduce code size and also the number of deprecation warnings about
2131  gluErrorString on Mac OS X 10.9.
2132
[ad3017d]2133* (Microsoft Windows version): aven: Try to work around redraw issues related
2134  to the measuring line by redrawing the whole window, which doesn't seem to be
2135  measurably slower.
2136
2137* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
2138  give an error rather than quietly ignoring the attempt.
2139
[77bdacf]2140* cad3d: Make cad3d remap control characters and spaces in station names when
2141  generating PLT output in the same way aven does.
2142
[ad3017d]2143* Various translation updates (particular thanks to Eric Madelaine and Dennis
2144  Baudys), including the start of a Bulgarian translation, with messages taken
2145  from Therion and elsewhere.
2146
2147* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
2148  GetUserDefaultUILanguage() to get the UI language to use.  For older
2149  versions, continue to use GetUserDefaultLCID().
[fb941bfd]2150
2151* (Microsoft Windows version): The Indonesian translation will now be used
2152  automatically when the system language is set to Indonesian.
2153
2154* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
2155  A. Riggs for his work on this.
2156
2157* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
2158  checksum check for the downloaded wx sources.
2159
2160* Fix a lot of the compiler warnings when building with clang.
2161
[ad3017d]2162* doc/manual.sgml: Add missing quantities to the list documented as accepted by
2163  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
2164  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
2165  mentioned in list of the units that can be set for them); COUNT (missing
2166  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
2167  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
2168
2169* Test suite: Improve test coverage for cavern.
2170
[0ecf3b1]2171Changes in 1.2.10 (2014-01-15):
2172
2173* aven: Fix assertion if two mouse buttons are held down at the same time.
2174  If dragging with more than one mouse button held down, releasing one causes
2175  another which is still held down to take effect.  Reported by Brian
2176  Clipstone.
2177
[53966d3]2178* aven: If we fail to start the external editor when the user clicks on an
2179  error or warning from cavern, show an error box.
2180
[6f0d0d8]2181* aven: If the survey has a title, add it as a top-level <title> element to
2182  exported SVG files.
2183
2184* aven: Escape '<', '>', and '&' in labels in exported SVG files.
2185
2186* aven: In GPX export, set the <time> element to the datestamp from the 3d
2187  file.
2188
2189* aven: Don't try to write the title if it isn't set or is empty when exporting
2190  GPX files.
2191
2192* aven: Don't bother looking up the printer page setup info when exporting.
2193
[0ecf3b1]2194* (Microsoft Windows version): aven: Fix crash on "File->Print" or
2195  "File->Export" under Windows XP, reported by Brian Clipstone.
2196
2197* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
2198  encoded filename which could occur if run without being asked to load a file
2199  on startup.
2200
2201* (Microsoft Windows version): aven: Compile with optimisation on.
2202
2203* img library, aven: Although processed CMAP data files are often referred to
2204  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
2205  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
2206  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
2207  continue to do so in case anyone is relying on it, but also check for the
2208  other extensions.
2209
2210* img library: Add new "datestamp_numeric" field to struct img giving the
2211  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
2212  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
2213  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
2214  timezone wrong.
2215
2216* img library: Fix my_strcasecmp() to handle top-bit set characters better.
2217
[6f0d0d8]2218* cavern: Fix NULL pointer dereference when processing Compass DAT file without
2219  'SURVEY DATE:'.
[0ecf3b1]2220
[6f0d0d8]2221* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]2222
[6f0d0d8]2223* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]2224
[53966d3]2225* Fix some compiler warnings if built with glibc's fortify source feature
2226  enabled.
2227
[6b6fb4d]2228Changes in 1.2.9 (2014-01-08):
2229
2230* Document --3d-version in cavern man page and the manual.
2231
2232* aven: Fix compilation error in movie export code with recent libavi.
2233
2234* aven: Fix warning on stderr when export a movie as MPEG.
2235
2236* img library: In non-hosted mode, don't define GETC and PUTC if they're
2237  already defined, to allow easy overriding with getc_unlocked() and
2238  putc_unlocked() (which are significantly faster on Linux).
2239
2240* img library: In non-hosted mode, check that int is at least 32 bits,
2241  and if not, use long.  In practice, platforms with 16 bit int are mostly
2242  obsolete, but it's not hard to be portable here.
2243
2244* img library: Add test that img.c and img.h compile in non-hosted mode
2245  (regression test for issue fixed in 1.2.8).
2246
2247* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
2248
2249* Update translations from launchpad and from existing similar messages.
2250
2251* Fix some compiler warnings.
2252
[e1f27c4]2253Changes in 1.2.8 (2013-10-29):
[da65891]2254
2255* cavern: Fix handling of anonymous wall stations ('..' by default) to
2256  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
2257  Holder.
2258
[e1f27c4]2259* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]2260  statistics when the value gets large.
2261
[a4adf09]2262* cavern: Eliminate redundant progress message when solving simultaneous
2263  equations.
2264
[e1f27c4]2265* aven: Add a format drop down to the export dialog, and only show fields which
2266  are meaningful and supported for the currently selected export format.  The
2267  format defaults to that used most recently.  The "Elements" and "View" boxes
2268  have been swapped in the print and export dialogs as that layout works much
2269  better when the "View" box is hidden.
2270
[0056ee1]2271* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
2272  - now works again.  Reported by Anthony Day.
2273
[e1f27c4]2274* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
2275  this release the projection which the survey coordinates are in defaults
2276  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
2277  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
2278  projection string.  The ability to specify this projection in a better
2279  way is coming soon.
2280
2281* aven: New export options "Origin in centre" and "Full coordinates" - the
2282  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
2283
2284* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
2285  time ago, so update references.
2286
2287* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
2288  with wxMSW 2.9.5.  Reported by Brian Clipstone.
2289
2290* aven: Make right click in an empty presentation mark the current position and
2291  open it to edit, instead of crashing.
2292
2293* aven: Update movie export code to work with latest libav API.  Reported by
2294  Sebastian Ramacher.
2295
2296* aven: Improve reporting of errors during the process of exporting a movie.
2297
2298* aven: Don't try to close the movie if we aren't producing one.
2299
2300* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
2301
2302* aven: Fix to build with wxMSW 2.9.5.
2303
2304* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
2305
2306* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
2307  ago, so add a new --skencil option to specify this output format.  The old
2308  name (--sketch) is still recognised for compatibility.
2309
2310* cad3d: Make --marker-size work for Skencil and SVG output.
2311
2312* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]2313
[88b54df6]2314* img library:
2315
[e1f27c4]2316  + Fix to work once more when used outside of Survex (missing definition of
2317    max() macro and a bad call to free() in img_close() for a file opened for
2318    reading).
2319
2320  + Use lround() instead of round(), and make the tests around whether we use
2321    the library function or the our fallback implementation saner.
2322
2323  + Fix // comments in C code for portability to pre-C99 compilers which don't
2324    support these as an extension.
[88b54df6]2325
[f807d8bf]2326  + Can now be compiled as C++ as well as as C.
2327
[e1f27c4]2328* (Microsoft Windows version): The installer is now built with a newer version
2329  of Innosetup, and includes translations for all the languages which Survex
2330  itself has any translations for.
2331
2332* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
2333
2334* Minor translation updates.
2335
2336* tests/Makefile.am: Distribute files for "normal_bad" testcase.
2337
[e34bebc]2338Changes in 1.2.7 (2013-07-27):
[65d9b6b]2339
[e34bebc]2340* Add support for anonymous stations, which are indicated by one, two or three
2341  separator characters - with the default separator of '.', that means '.',
2342  '..', and '...' are anonymous stations.  Single separator ('.' by default)
2343  is an anonymous non-wall point, double separator ('..' by default)
[a5c74f2]2344  is an anonymous wall point at the end of an implicit splay), and triple
2345  separator ('...' by default) is an anonymous point (with nothing special about
[e34bebc]2346  the leg).  A new *alias command allows '-' to be mapped to '..' for
2347  compatibility with pocket topo: *alias station - ..
[07beaa4]2348
[e34bebc]2349* New version 8 of the 3d format:
[07beaa4]2350
[e34bebc]2351  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]2352
[e34bebc]2353  + New explicit file-wide flag for 'this is an extended elevation', rather
2354    than modifying the survey title to indicate this.
[da9d788]2355
[e34bebc]2356  + The survey prefix is often unchanged from one leg to the next, so use a
2357    spare flag to compactly indicate when there's no label change.
[da9d788]2358
[e34bebc]2359  + The data style of each leg is now stored.
[da9d788]2360
[e34bebc]2361  + The "processed at" time is stored as seconds since 1970 rather than a
2362    human-readable string.
[da9d788]2363
[e34bebc]2364  + Since 3d v8 features significant changes to the format, the format
2365    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]2366
[e34bebc]2367* img library:
[da9d788]2368
[e34bebc]2369  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]2370
[e34bebc]2371  + Handle .pos files containing unnamed stations - don't suck the next line in
2372    as the station name, and set img_SFLAG_ANON for them.
[da9d788]2373
[e34bebc]2374  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
2375    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
2376    elevation, in place of appending " (extended)" to the title.  Internally we
2377    still append this to the title (and remove it upon reading) when writing
2378    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
2379    explicitly in the file.
[da9d788]2380
[e34bebc]2381  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]2382
[e34bebc]2383* aven:
[da9d788]2384
[e34bebc]2385  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
2386    now, and the wx developers consider even 2.8 to be rather long in the
2387    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
2388    formally dropping support for older versions allows a number of workarounds
2389    to be removed from the aven source code.  Also, features deprecated in
2390    wxWidgets 2.9 are no longer used in our code.
[da9d788]2391
[e34bebc]2392  + Don't run incremental search on every key-press, as on a slow machine the
2393    short initial search(es) will take a while but not be useful.  Instead only
2394    actually run the search when we're told there are no more key-presses
2395    queued up.
[da9d788]2396
[e34bebc]2397  + Implement support for including cross-section information in exported SVG
2398    and DXF files (ticket#4).  The DXF export is untested currently.
2399
2400  + Show splay legs faded by default, with menu options to hide them or show
2401    them like other legs.
2402
2403  + Speed up loading a .3d file with cross-sections by using a map to convert
2404    station names to positions.
2405
2406  + In the cavern log window, don't highlight a file:linenumber if there's no
2407    message after it, which avoids highlighting the "Included from" lines
2408    wrongly.
2409
2410  + Fix not to crash when trying to report an error while starting up.
2411
2412  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
2413    the OS X standard shortcut Shift-Command-F (previously we used F11, but
2414    that's used by the desktop).
2415
2416  + Add checks for errors when reading the font file.
[07beaa4]2417
[e34bebc]2418  + Remove useless extra quoting when invoking vim to show the location of an
2419    error from cavern.
[07beaa4]2420
[e34bebc]2421  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]2422
[e34bebc]2423  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2424    in the dialog in sync.
[da9d788]2425
[e34bebc]2426* cavern:
[3dfffa2]2427
[e34bebc]2428  + Demote errors about invalid dates to warnings, since we've accepted *date
2429    for ages without any checks on the value, and so existing datasets
2430    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]2431
[e34bebc]2432  + New *alias command allows '-' to be mapped to '..' for compatibility with
2433    pocket topo: *alias station - ..
[07beaa4]2434
[e34bebc]2435  + We want to warn if there's a clino reading which it would be impossible to
2436    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2437    read "93" (it's probably a typo e.g. for "39").  However, the gradient
2438    reading from a topofil is typically in the range 0 to 180, with 90 being
2439    horizontal.  Really we should allow the valid range to be explicitly
2440    specified, but for now we infer it from the zero error - if this is within
2441    45 degrees of 90 then we assume the instrument can read between 0 and 180
2442    degrees.
[da9d788]2443
[e34bebc]2444  + If the survey isn't all connected, still run survey tree checks and report
2445    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
2446    Dixon for the report which highlighted this issue.
[da9d788]2447
[e34bebc]2448  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]2449
[e34bebc]2450  + Report column numbers as well as line numbers for some cavern errors and
2451    warnings.
[07beaa4]2452
[e34bebc]2453  + Adjust width of node stats table to fit longest count when there are more
2454    than 9999 of a particular order of node.
[07beaa4]2455
[e34bebc]2456  + If the argument to *include has an opening double quote but the closing
2457    double quote is missing, then skip trying to open the file.
[da9d788]2458
[e34bebc]2459  + Move "Station X referred to just once" warning after non-existent survey
2460    check - if both fire, the non-existent survey error is likely to be more
2461    relevant.
[da9d788]2462
[e34bebc]2463  + We no longer follow an error for a bad reading in passage data with a bogus
2464    "End of line not blank" error, but instead check the remaining readings on
2465    the same line.
[da9d788]2466
[e34bebc]2467  + We no longer follow an error about OMIT for a required reading with a bogus
2468    "End of line not blank" error.
[7f6250a]2469
[e34bebc]2470  + Report an error if the scale factor in *calibrate is zero - it doesn't make
2471    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]2472
[e34bebc]2473  + Report the parent include files starting from the outermost, as that's more
2474    logical when there are multiple levels involved.
[07beaa4]2475
[e34bebc]2476  + If we were expecting a numeric field and instead get something which starts
2477    with '+', '-', or '.' but which isn't a number, then fix the error to
2478    include that character in the token reported.
[3dfffa2]2479
[e34bebc]2480  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2481    first item.
[07beaa4]2482
[e34bebc]2483* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]2484
[e34bebc]2485* dump3d:
[07beaa4]2486
[e34bebc]2487  + Build, install and package dump3d as standard - it's useful for grabbing
2488    info from 3d files in scripts.
[07beaa4]2489
[e34bebc]2490  + Add --show-dates option.
[07beaa4]2491
[e34bebc]2492  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]2493
[e34bebc]2494  + Report the data style of legs.
[da9d788]2495
[e34bebc]2496  + Report if the file is an extended elevation.
2497
2498  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]2499
2500* Test suite:
2501
2502  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2503    expected output so it passes reliably.
2504
[e34bebc]2505  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2506    'Deleted' stations upon failure are the more natural way round.
2507
[07beaa4]2508  + Add more testcases, expand some existing testcases, and add expected output
2509    for more.
2510
[e34bebc]2511* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2512  appropriate C and C++ compilers to use, and link mingw build statically to
2513  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]2514
2515* (Unix version): When determining the character set for command-line tools,
2516  check environmental variable LANG after LC_ALL and LC_CTYPE.
2517
2518* When determining the language, check environmental variable LC_ALL before
2519  LC_MESSAGES and LANG (but after SURVEXLANG).
2520
[e34bebc]2521* If we don't find the message file, only give an error if it was specified
[665183c]2522  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]2523  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2524  settings.
2525
2526* There are a handful of hard-coded English message strings for reporting
2527  errors trying loading message files, etc.  These are all now ASCII, as if we
2528  fail trying to open a message file, it's more likely the encoding isn't
2529  set correctly.
2530
2531* Prune strings we are no longer using and are probably unlikely to use again
2532  into a new file po_codes_dead, so that translators don't get presented with
2533  them to translate.
2534
[07beaa4]2535* Merge lots of translation updates.  Most translations are now complete or
2536  close to complete.
[3dfffa2]2537
2538* Add start of Indonesian translation from Arief Setiadi Wibowo.
2539
[07beaa4]2540* Fix various compiler warnings when building from source.
2541
[e34bebc]2542* Include scripts gdtconvert and gen_img2aven in the source distribution.
2543
[c575465]2544Changes in 1.2.6 (2012-02-23):
[b081031]2545
2546* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2547
2548* (Microsoft Windows version): Include JPEG images for aven in the installer
2549  package (ticket#35).
2550
2551* cavern: If we have a reference to a station in a non-existent survey, give a
2552  helpful error rather than saying the station hasn't been exported from the
2553  survey.  (Bug reported by Martin Green via email)
2554
2555* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
2556  Kahler.
2557
2558* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]2559  .gpx file with waypoints for entrances.  This needs libproj so is disabled
2560  by default for this release - to enable it install the development stuff for
2561  libproj and build survex with:
2562
2563      make FINDENTRANCES=findentrances
2564      make install FINDENTRANCES=findentrances
[b081031]2565
2566* dump3d: Add support for showing img_ERROR_INFO items.
2567
2568* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2569
2570* Incorporate a French translation from launchpad I'd previously copied the
2571  English version of by mistake.  Attempt to correct mistranslation of "survey
2572  file".
2573
[685116f]2574Changes in 1.2.5 (2012-01-03):
2575
2576* aven:
2577
2578  + The survey tree in the left panel is now in sorted order once more.
2579
2580  + No longer fails with an assertion if used for a long time (we were leaking
2581    an OpenGL list each time one had to be regenerated).
2582
2583  + Now builds with newer FFmpeg library.
2584
2585  + Draw measuring line in front of the indicators rather than behind them.
2586
2587  + Loading a new file (or reloading the current one) no longer invalidates
2588    the OpenGL lists for the compass and clino, so will be a fraction faster.
2589
2590* Improve handling of attempts to look up translated messages before the
2591  message subsystem is fully initialised (which only happens if there's an
2592  error early on).
2593
2594* Improve the survex(7) man page text, and fix it to be marked as section 7 in
2595  the man page source as well as in the filename.
2596
[f15ca67f]2597Changes in 1.2.4 (2012-01-01):
2598
2599* aven:
2600
2601  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2602    initialised, which doesn't cause problems in some machines, but causes aven
2603    to abort on others.  This is now fixed, and there's a check in place to
2604    help avoid similar issues in future. (ticket#34)
2605
2606  + Always use metres or feet for the depth colour key, and chose a consistent
2607    precision by looking at the depth range. (ticket#30)
2608
2609  + Show the depth units below the colour bar rather than after every value.
2610
2611  + When zooming way in, stay in metres rather than switching to cm.
2612
2613  + On the scale bar, say “1 mile” rather than “1 miles”.
2614
2615* Translation updates for Catalan, French and Slovak.
2616
[5b9942e]2617Changes in 1.2.3 (2011-12-31):
2618
2619* Fix to build with wxWidgets 2.9.2.
2620
2621* (Mac OS X version):
2622
2623  + Processing .svx files from aven now works.
2624
2625  + Remove spurious blank lines from the licence text in "Get Info".
2626
2627  + Don't create the help menu at all, as it is empty (because the "About"
2628    entry goes elsewhere) and sometimes seems to appear in the UI.
2629
2630  + INSTALL.OSX: Update to reflect current status.
2631
2632* aven:
2633
2634  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
2635
2636  + Improvements to text plotted on the survey pane:
2637
2638    - Support plotting Unicode character points > 256 by lazily loading the
2639      data for them from the font file and plotting them with a direct call to
2640      glBitmap(), which is slower but doesn't require a display list per
2641      character.
2642
2643    - Adjust the spacing from fixed width to putting a one pixel gap either
2644      side of each one character (so two between adjacent glyphs).  Mostly this
2645      reduces the horizontal width, but it adds a pixel for characters like "m"
2646      and two in a few cases.
2647
2648    - Fix .pixelfont file generation to correctly handle characters wider than
2649      8 pixels.
2650
2651  + Fix expected cross shape so don't always reject using texture mapping to
2652    draw crosses.
2653
[3ea0178]2654  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2655    as those consisting of just one.  Previously we would trip over the empty
2656    tube later.  Such tubes can for example be created by extend if a splay shot
2657    is the start or end of a tube.
2658
[5b9942e]2659  + Make the green colour used for entrances in the survey tree the same
2660    (slightly darker than before) green used for the entrance blobs.
2661
2662  + Report the version of the library we're actually running with if built
2663    against wx >= 2.9.2.  Make it clear that the version reported is the
2664    version *built* with for wx < 2.9.2.
2665
[3ea0178]2666* extend:
2667
2668  + Copy the end markers for passage tubes.
[5b9942e]2669
[3ea0178]2670  + Preserve left and right data for tubes (previously they were set to -1.0
2671    which means "no info").
2672
2673* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2674  was no longer used - it certainly is!
2675
2676* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2677  messages, and curly single right quote instead of straight ASCII apostrophe.
2678  Fall back to using straight ASCII versions if we can't represent them in the
2679  current character set.
[5b9942e]2680
[3ea0178]2681* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]2682
2683* Test suite:
2684
2685  + Add test coverage for interleaved diving data.
2686
2687  + Add testcase for diving data with topofil-style distance.
2688
[94960ad]2689Changes in 1.2.2 (2011-10-06):
2690
2691* aven:
2692
2693  + Replace the textured-mapped font drawing with an approach based on
2694    glBitmap.  This doesn't suffer from the character alignment issues which
2695    the textured-mapped fonts had, and is actually significantly faster on some
2696    machines.  The current font used is (mostly) fixed-width, but this isn't an
2697    inherent limitation - it was just the easiest font data to convert to a
2698    usable format.
2699
2700  + Fix assertion failure due to rounding differences on loading certain .3d
2701    files.  (ticket#26)
2702
2703  + Fix assertion failure when turning on 3D passages if they stick out higher
2704    or lower than any station.  (ticket#29)
2705
[53f8a93]2706  + Fix grid not to disappear when blobs are turned on and blobs are drawn
2707    using lines.
2708
[94960ad]2709  + If a degree sign isn't available in the character set in use, transliterate
2710    it to 'dg' rather than skipping it.
2711
2712  + Fix message which should have been a degree sign but got lost in the format
2713    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
2714    that bearings in the status bar now have a degree sign after them if they
2715    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2716
2717  + Fix print dialog to calculate the scale required for "One page" right
2718    before it calculates how many pages are required, so we don't end up
2719    something other than 1x1 being shown when the user changes settings.
2720
2721  + Update the calculations for picking a scale and for deciding how many
2722    pages are needed to take into account the change in info box height made
2723    in 1.2.1.
2724
[9704252]2725Changes in 1.2.1 (2011-10-04):
[e3c58c3]2726
2727* Translation updates for US English.
2728
2729* aven:
2730
2731  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2732    it now shows colours for dates and errors as well as depths.
2733
2734  + In the colour key for "colour by date", change "No info" to "Undated".
2735
2736  + Remove the dark grey background from the colour key and just put a single
2737    pixel black border around the colours.  This is more in keeping with the
2738    other controls, and means the colours are now on a black background so more
2739    visually similar to the survey legs.
2740
2741  + Move the colour key's "Undated"/"Not in loop" entry down a little to
2742    improve the appearance.  Make each section a pixel taller.
2743
[9704252]2744  + Allow "Colour by X" to be selected even if there's no data for X or only a
2745    single value of X used (the colour key is much smaller in these cases, and
2746    does still provide some useful information).
2747
2748  + Fix incorrect calculation of depth colouring for survey legs which straddle
2749    a depth band boundary.
[e3c58c3]2750
2751  + The scale bar, compass, clino, and colour key now all have right click
[9704252]2752    menus which allow related actions to be performed (especially handy in
2753    full-screen mode).
[e3c58c3]2754
2755  + Improve the font used on the survey pane - it now contains the '-'
2756    character (so the clino now shows negative angles as negative, and dates
2757    in the colour key are now hyphenated).  Also the spacing and alignment
2758    are a little better, though still not perfect.
2759
2760  + PLT file export now handles spaces and control characters in station names
2761    by escaping them with '%' as in URLs.
2762
2763  + Pressing "Enter" on a station in the tree control now centres the view on
2764    that station.
2765
2766  + The scale bar is now cached in an OpenGL display list since it often gets
2767    redrawn exactly the same - for example, when rotating, panning, etc.
2768
2769  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2770    then forces a refresh of the survey pane.  This is intended as a debugging
2771    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]2772    where a list should have been invalidated (please report if you find such
2773    a case as it is a bug).
[e3c58c3]2774
[9704252]2775  + We now automatically track which OpenGL display lists need to be
2776    invalidated on window width or height changes.
[e3c58c3]2777
2778  + Increase scale bar maximum width from 65% of the window width to 75% as it
2779    was in 1.0.x (except that if that would overlap the clino we now reduce
2780    that proportion down until it reaches 50%).  Make the limit of zooming in
2781    the same as in 1.0.x.  (ticket#23)
2782
[9704252]2783  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2784    the application was fullscreen (the dialog got opened under the main
2785    window!)  To work around this, aven would switch out of full screen mode
2786    temporarily while showing a dialog.  This case works properly with recent
2787    wxGTK, so disable our workaround with versions we know work.  Also, apply
2788    the workaround only for wxGTK, not everywhere except on Microsoft Windows
2789    as there's no reason to think we need it for other platforms.
[e3c58c3]2790
2791  + Grey out the "View North" action when we're already viewing North, and
2792    similarly for other compass points.
2793
2794  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
2795    info in the "About" dialog.
2796
2797  + Fix to set the correct filename on the root of the survey tree - previously
2798    the filename of the previous file loaded was used!
2799
2800  + The movie export code now works with newer versions of the FFmpeg libraries
2801    as well as still working with older versions.
2802
2803  + Fix mixed up messages - the print dialog now says "View" on the left
2804    subgroup of controls rather than some unrelated message.
2805
2806  + On printouts, combine the "Plan View"/"Elevation" info box field with the
2807    field which gives the bearing and reduce the height on the info box by the
2808    removed field, so it's now 3cm for plans and elevations, as for extended
2809    elevations.  Report the tilt angle for tilted elevations which it seems has
2810    been missing for ages (it's not in recent 1.0.x either).
2811
2812  + Tweak the exact positioning of informational text on printouts to look
2813    nicer and make better use of the available space.
2814
2815  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
2816    dialog.
2817
2818  + Make the sign of the tilt angle for printouts consistent with the sign
2819    shown by the "clino" in the survey pane.
2820
2821  + In the "Print" dialog, when in plan view disable the "Plan view" button,
2822    and similarly for the "Elevation" button.
2823
[9704252]2824  + (Microsoft Windows version): Sort out appearance of custom cursors.
2825
[e3c58c3]2826  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
2827
2828  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
2829    you can't get out again easily, so add code to explicitly check for F11
2830    being pressed and toggle full screen.
2831
2832* (Linux version): Fix the RPM .spec file for where man pages now get installed
2833  and package aven.svg and the vim support files.  (Fixes from James Begley)
2834
2835* "make check" now performs several checks on the translation files.
2836
2837* More messages are now available to be translated.
2838
2839* cavern: Fix reporting of ranges of survey coordinates, which was broken by
2840  the message handling changes in 1.2.0.
2841
2842* Fix warning when compiling with GCC.
2843
2844* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
2845  sudo for installing on Unix.
2846
2847* In the manual, replace the instructions for building from source with a
2848  pointer to the clearer instructions in INSTALL.
2849
2850* In the manual, make it clear that installing with administrator rights
2851  also applies to newer platforms than XP.
2852
2853* doc/TODO.htm: Update.
2854
[120c1c6]2855Changes in 1.2.0 (2011-09-20):
[b4ac7007]2856
2857* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
2858  English.
2859
[9cfcb3f]2860* tests/smoke.tst: aven no longer requires an X display for --help or
2861  --version, so replace skip of this check with a check that this remains the
2862  case.
2863
2864* We now use the standard .po and .pot file formats for storing translations
2865  (rather than the Survex-specific messages.txt format), and then translate
2866  these into Survex's .msg format.
2867
[b4ac7007]2868* (Unix version): Move survex man page to section 7 (since it isn't documenting
2869  an actual command).
2870
[9cfcb3f]2871* (Unix version): Write each generated man page to a temporary file, then
2872  atomically rename, to avoid leaving an empty or partial man page behind if
2873  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
2874  recurrence of that).
2875
[b4ac7007]2876* (Unix version): Default to installing docs into /usr/share/doc/survex rather
2877  than /usr/doc/survex.
2878
2879* aven:
2880
[120c1c6]2881  + Fix handling of accented characters in the survey pane.
2882
[9cfcb3f]2883  + Aven icon redrawn in SVG format - it's now a vector image which looks
2884    nicer at larger sizes.
2885
[b4ac7007]2886  + Explicitly request double-buffering, which seems to be needed for systems
2887    with GLX >= 1.3.
2888
2889  + Fix crash while trying to load certain .3d files.
2890
2891  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]2892    Currently this is disabled in Microsoft Windows builds, pending getting the
2893    required libraries set up for building releases.
[b4ac7007]2894
2895  + Reporting of errors during movie export improved.
2896
2897  + Force playback speed to "x1" during movie export.
2898
2899  + Use stock IDs for buttons where appropriate - such buttons may now be
2900    rendered with icons on some platforms.
2901
[9cfcb3f]2902  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
2903    ISO8859-1).
2904
2905  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
2906    as it's no longer required with modern versions.
2907
2908  + Don't redraw the survey on every mouse movement in the survey pane unless
2909    the measuring line is (or just was) active.  (ticket #17)
2910
[b4ac7007]2911* cavern:
2912
2913  + Drop "non-fatal" from the report of how many errors there were at the end
2914    of the run - it just confuses users - we won't even get here if there's a
2915    fatal error!
2916
[9cfcb3f]2917  + Add --3d-version option to allow the user to specify the version of the 3d
2918    format to output.  (ticket#21)
2919
2920* img library:
2921
2922  + Make the highest and lowest valid values for img_output_version available
2923    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
2924
[b4ac7007]2925* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]2926  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]2927
[8f9b0b6d]2928Changes in 1.1.16 (2011-05-16):
[ecdb631]2929
2930* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
2931  Portuguese, and US English.
2932
2933* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]2934  rather than '->' where these characters are available.
[ecdb631]2935
2936* (Unix version): Link with -lGL, if it exists, to support linking with gold or
2937  GNU ld --as-needed (Debian bug #615781).
2938
2939* img.c:
2940
2941  + Fix code typo for IMG_API_VERSION == 0 case.
2942
2943  + Fix code typo in code used when IMG_HOSTED isn't defined.
2944
2945* doc/TODO.htm: Remove entries which have now been done.
2946
[8f9b0b6d]2947* (Microsoft Windows version): aven: We now include all the available
2948  translations for messages from wxWidgets, which means that standard widgets
2949  will appear translated where available even if Survex messages aren't
2950  translated.
2951
[f5e3521]2952Changes in 1.1.15 (2010-10-15):
[2d16e4e]2953
2954* aven:
2955
2956  + In the cavern log window, change the "Rerun" button to "Reprocess" to
2957    follow terminology in manual and elsewhere.  Fixes ticket#15.
2958
2959  + When displaying output from cavern, don't update the window after every
2960    line, but only when we don't have data from cavern pending.  Hopefully
2961    addresses ticket#12.
2962
2963  + If we aren't using GL_POINTS for blobs, draw them using a series of
2964    abutting lines rather than with gluDisk which is faster and gives a
2965    consistent shape.
2966
2967  + Check whether blobs and crosses actually render correctly as points/point
2968    sprites, and if they don't, fall back to drawing them with lines.  The
2969    best method is cached on disk, and rechecked automatically if the graphics
2970    hardware is changed or the drivers upgraded.
2971
2972  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
2973    though, so we still enable USE_FNT by default).
2974
2975  + Don't offer "All files" wildcard in presentation save dialog.
2976
2977  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
2978    more places.
2979
2980  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]2981    when running cavern from aven.  Fixes ticket#11.
2982
2983* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
2984
2985* diffpos: Handle files with duplicate labels in better - extend generates
2986  duplicate labels when it breaks a loop.
2987
2988* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]2989
2990* New v7 of .3d format which stores survey dates as number of days since
2991  January 1st 1900, so we now support dates from 1900-2078 (rather than
2992  1970-2037) with a smaller file size.  The img API is now versioned - you
2993  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
2994  gives the survey dates in days in days1 and days2 instead of as time_t
2995  values in date1 and date2.  Fixes ticket#14.
2996
2997* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
2998  former has been the canonical name for some time, with www.survex.com just
2999  redirecting to it.
3000
3001* (Unix version): Use unlocked file I/O if available, which can be much faster
3002  in some cases (we don't need the locking as we don't do multithreaded file
3003  I/O).
3004
3005* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
3006  headers.
3007
3008* (Mac version): buildmacosx.sh now works again.
3009
3010* Most tests weren't actually running any testcases (looks like a sh
3011  portability issue).  This is now fixed, and fortunately all tests still pass.
3012
3013* Include the extra .isl translation files for Innosetup in the source archive.
3014
[f9473ab]3015Changes in 1.1.14 (2010-07-26):
3016
3017* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
3018
3019* aven:
3020
3021  + After processing survey data, if there were warnings or errors, add a
3022    "Rerun" button to allow easy reprocessing after fixing problems.  If there
3023    were only warnings, also add an "OK" button to allow moving on to viewing
3024    the processed survey data (fixes ticket#13).
3025
3026  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
3027
3028  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
3029    not the ': ' after), and to make the title for the terminal the
3030    warning/error message.  Avoid false positives by checking that '<line>' is
3031    a number.
3032
3033  + Don't double escape the contents of href and target in links in the cavern
3034    log window.
3035
3036  + Improve handling of the splitter window, fixing behavioural glitches in
3037    various cases.
3038
3039  + Highlight stations matching any current search when a file is loaded.
3040    (ticket#9)
3041
3042  + (Mac version): Fix build issue due to Mac OS X polluting the global
3043    namespace with its own "Point" class.
3044
3045  + (Unix version): The Gnome print dialog has its own preview window so
3046    suppress ours if using the Gnome one.
3047
3048  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
3049
3050  + (Microsoft Windows version): Fix handling of a double-click on the survey
3051    tree when built with wxWidgets >= 2.8.11.
3052
3053* cavern: Report relevant file and line number for three warnings which didn't
3054  give them before.
3055
3056* (Unix and Mac versions): configure: Update the wx-config probing code -
3057  wxmac-config etc aren't present with newer wxWidgets versions so there's no
3058  point looking for them now.
3059
3060* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
3061  for easy installation.  Update it to work with the latest Survex versions
3062  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
3063  private wxWidgets, use 2.8.11 not 2.7.0-1).
3064
3065* manual:
3066
3067  + Correctly capitalise "GTK".
3068
3069  + Note that on Linux we only regularly test builds with the GTK+ version
3070    (change taken from 1.0).
3071
3072* Fixed the cad3d man page, which was an empty file in 1.1.13.
3073
[0bd49eb]3074Changes in 1.1.13 (2010-06-16):
[90d0d71]3075
3076* Say "wxWidgets" instead of "wxWindows" consistently.
3077
[739b92c]3078* img.c: Fix small memory leak (filename_opened member).
[90d0d71]3079
3080* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]3081
3082* aven:
3083
[90d0d71]3084  + wxWidgets 2.6.0 or newer is now required.
3085
3086  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
3087    work but hasn't been tested recently (all packaged versions of wxWidgets
3088    seem to be Unicode now).
3089
3090  + Fix potential uses of uninitialised variables which may have been causing
3091    occasional glitches when loading a file on start-up.
3092
[e4bfd2f]3093  + Improvements to the handling of the font used for plotting labels and other
3094    text on the survey pane:
3095
3096    - Loading the font file is more efficient.
3097
3098    - Character spacing is improved.
3099
3100    - Default font is now anti-aliased.
[90d0d71]3101
3102  + "About" dialog:
3103
3104    - Add "Copy" button to copy the system info to the clipboard for easier
3105      bug reporting.
3106
3107    - List OpenGL extensions last, since there are usually lots of them with a
3108      modern gfx card.
3109
3110    - Fix 100% CPU usage while the "About" dialog is open.
3111
3112  + Processing .svx files:
3113
3114    - Passing a .svx file on the command line now works better.
[1324d6c]3115
[739b92c]3116    - Put the survey data log window in a splitter in the usual frame rather
3117      than opening a separate frame for it.
3118
[90d0d71]3119    - Auto-scroll the log window until we've reported a warning or error.
3120
3121    - Fix small memory leak.
3122
3123  + The presentation filename now defaults to using the basename of the
3124    currently loaded dataset, but we always prompt before we first save with
3125    such a name.
3126
3127  + Reduce memory usage when saving a screenshot.
3128
[e4bfd2f]3129  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
3130    persist the window size (and maximised or fullscreen state) between
3131    invocations.
3132
[90d0d71]3133  + Fix reporting of OpenGL errors.
3134
3135  + Fix glitches when tilting while looking East.
3136
[739b92c]3137  + Added Portuguese and Slovak translations of wxWidgets messages.
3138
[90d0d71]3139* Documentation:
3140
[e4bfd2f]3141  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
3142
3143  + Drop the "alternative manual formats" self-extracting zip file - people
3144    will generally just want one of the formats, so downloading several
3145    together isn't very useful.
3146
[90d0d71]3147  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
3148
3149  + GPL.htm: Replace HTML version of licence with a link to the version on
3150    the FSF website.
3151
3152  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
3153    low level to be of interest to non-developers, and developers can look at
3154    the source code.
3155
3156* (Unix version): configure: New preferred name for specifying wx-config script
3157  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]3158
[e4bfd2f]3159* (Linux version): Source RPM package dropped as you can just build an RPM
3160  package from the source tarball.
3161
[739b92c]3162* (Microsoft Windows version): The installer is now created with a newer
3163  version of InnoSetup, which gives a 10% smaller download.
3164
[2e12f8c]3165Changes in 1.1.12 (2007-02-07):
[5940815]3166
3167* aven:
3168
[3db0798]3169  + Remember the window size or maximised/fullscreen state between invocations.
3170
[5940815]3171  + Add options dialog to "Export" similar to the one for "Print".
3172
[6b2113d]3173  + The "number of pages required" in the print dialog now updates when you
3174    change what is to be shown (underground legs/surface legs/station
3175    names/crosses).
3176

3178
3179* Updated Czech, Spanish, and Slovak translations.
3180
[99d8798]3181* (MacOS X version): Assorted OS X specific tweaks and fixes.
3182
[920b066]3183* aven:
[78c67a6]3184
[920b066]3185  + Pick a smaller and clearer font for labels.
[99d8798]3186
[920b066]3187  + Fix character spacing.
[99d8798]3188
[920b066]3189  + Tweak display of bearing and elevation angles to look nicer with
3190    proportional fonts.
[99d8798]3191
[920b066]3192  + Use the title from the 3d (or plt, etc) file for the window title
3193    rather than the filename.
[99d8798]3194
[920b066]3195  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]3196
[920b066]3197  + Only consider underground legs when calculating the depth bands and
3198    depth colouring.
[99d8798]3199
[920b066]3200  + Add "Colour by Error".
[99d8798]3201
[920b066]3202  + Add entry for "white" in date and error keys.
[99d8798]3203
[920b066]3204  + When setting the view to a single point, don't change the scale.
[99d8798]3205
[920b066]3206  + If reloading the same file, don't change the view
[99d8798]3207
[920b066]3208  + Fix filetypes selector in open dialog.
[99d8798]3209
[920b066]3210  + Fix the charset we use for aven in certain cases.
[99d8798]3211
[920b066]3212  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]3213
[920b066]3214  + Pass wx the full language code to initialise the C library locale.
[99d8798]3215
[920b066]3216  + Fix bug in generating prefix tree view which could lead to a bogus
3217    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]3218
[920b066]3219  + "New Presentation" now ensures that the side panel is open
[99d8798]3220
[920b066]3221  + Fix updating of cached opengl lists when the view is reset to the
3222    default.
[99d8798]3223
[920b066]3224* Ignore LANG if it starts with a digit to avoid problems with bogus value for
3225  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]3226
[920b066]3227* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
3228  specified.  Either/both can be set to ":".
[99d8798]3229
[920b066]3230* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]3231
[920b066]3232* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]3233
[920b066]3234Changes in 1.1.10 (2006-07-14):
[ac3f376]3235
3236* aven: Clicking on a survey name in the survey tree now highlights it in
3237  the map view.  Double-clicking zooms the view to show the clicked survey
3238  highlighted.  Clicking the root clears the highlighting and double-clicking
3239  the root restores the default view.  To expand/collapse a branch, click
3240  on the "[+]" or "[-]" icon to the left of the survey name.
3241
3242* aven: The measuring line can now measure to anywhere in plan or elevation
3243  view (not just to a station!)  In plan view the horizontal distance and
3244  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]3245
[ac3f376]3246* aven: Moving the mouse over a station in the survey view now highlights
3247  that station in the survey tree (though it may not be visible if the
3248  survey(s) it is in aren't expanded).
3249
3250* aven: Clicking on a station to centre the view now moves the mouse pointer
3251  to the new location of the station (except on Mac OS X where this isn't
3252  allowed).
3253
3254* aven: Fix which presentation toolbar buttons are shown as depressed.
3255
3256* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
3257
3258* vim files are now installed with the correct paths (bug introduced in 1.1.9).
3259
[920b066]3260Changes in 1.1.9 (2006-07-04):
[6a2594be]3261
3262* (Unix version): Install desktop files for aven and svxedit contributed to the
3263  Ubuntu package by Phil Bull, and corresponding pixmaps.
3264
3265* Fix img to filter out cross-sections which don't match the subsurvey (if
3266  specified).  The API now returns img_XSECT_END to mark the end of a
3267  passage rather than setting a flag on the last img_XSECT of the passage.
3268
3269* Enhance integration with the vim editor - this can now colour .err files, run
3270  cavern from vim and parse error output, and run aven from vim.  Tweak the
3271  existing vim mode for .svx files to fix a few minor bugs and add support for
3272  the new "*data passage" style.
3273
3274* aven: fix drawing of the "blob" end of the measuring line on graphics cards
3275  which can't draw large enough blobs for us.
3276
3277* aven: sort out confusion about what encoding everything is in which means
3278  that the distance measured by the measuring line actually gets displayed
3279  and also fixes problems with empty menu items in non-English locales in
3280  some cases.
3281
3282* aven: redraw grey background after a menu is closed over the aven window
3283  with no survey loaded.
3284
3285* aven: fix bug which caused printing to crash (introduced in 1.1.8).
3286
3287* aven: avoid crash on some machines when opening "About" dialog before having
3288  loaded a survey.
3289
3290* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
3291
3292* (Unix version): aven: Fix character set handling of cavern output.
3293
3294* cavern: Report an error if a cross-section is specified for a station which
3295  doesn't exist.
3296
3297* Updated French and Italian translations.
3298
3299* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]3300  `${prefix}/share/survex'" error.
3301
[6a2594be]3302* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
3303  (doesn't affect Survex itself, but other applications which use img.c should
3304  update their copy).
3305
3306* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
3307  and later are caught by configure, whereas older wx versions are caught when
3308  trying to compile).
3309
[920b066]3310Changes in 1.1.8 (2006.06.30):
[cd39f67]3311
[c988ae4]3312* Drop support for building with wxWidgets versions prior to 2.4.0
3313  (which was released on 2003-01-07).
3314
[9577fcc]3315* aven: Printing through aven now uses settings from the "[aven]" section
3316  of print.ini, and support for hierarchical sections (using "like=")
3317  has been disabled.
3318
[ecf2d23]3319* aven: Change mouse actions to be compatible with those in Survex 1.0.
3320  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
3321  left drag is now smart about not rotating and zooming at the same
3322  time.
3323
[d1628e8e]3324* aven: Highlighting stations now happens as you type, and pressing
3325  "Enter" or clicking the "Find" button now pans and zooms to show the
3326  highlighted stations.
3327
[e67ed1b]3328* aven: Left-clicking away from a station now cancels measuring line.
3329
[3ddd351]3330* aven: Setting view to North, South, East, or West is now animated like
3331  the tilt from plan to elevation.
3332
[c988ae4]3333* aven: Fix presentation saving to also write "." for decimal points and
3334  presentation loading to accept either "." or ",".
3335
3336* (Unix version): aven: Add text for all toolbar items so that aven
3337  will work with the Gnome desktop preference for displaying toolbars as
3338  icons with text or just text (wxWidgets needs fixing first though).
3339
3340* (Unix version): aven: Remove the ability to detach the menu bar (yell
3341  if you actually used it and I'll restore it!)
3342
3343* aven: Add "all survey files" option to the "open file" dialog.
3344
[84f1ed1]3345* (MS Windows version): aven: Fix cursor keys to pan survey.
3346
[a884696]3347* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
3348
[9fe7af4f]3349* (MS Windows version): Fix installer to work on Windows 2000 or XP if
3350  run by an unprivileged user.
3351
3352* (MS Windows version): Upgrade to the latest version of InnoSetup (the
3353  installer builder we use) and include new installer translations for
3354  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
3355
3356* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
3357  translations of messages for wxWidgets (the GUI library we use).
3358
[cd39f67]3359* aven: Disable "Highlight exported points" if there aren't any.
3360
[afffec4]3361* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]3362  Italian, Catalan, Spanish, and Romanian translations.
[581624b]3363
[38a192d]3364* (Unix version): test suite: fix smoke test to pass even without X running
3365  (it was meant to but the code had a bug).
3366
[5892e08]3367* aven: Check if OpenGL is available and exit cleanly with a helpful error
3368  if it isn't.
3369
[879e9c3]3370* (Unix version): aven: Fix --help and --version to work without a working
3371  X display (provided it's built with wxWidgets 2.5.1 or newer).
3372
[c8f929b]3373* aven: Automatically select the presentation tab of the notebook when the user
3374  selects "New Presentation" or "Open Presentation".
3375
3376* aven: Fix "Delete" in the presentation list to not get passed on (and so not
3377  reset to default view as well).
3378
3379* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
3380  empty.
3381
3382* aven: Fix Cursor Up and Down in the presentation list to move the highlight
3383  up and down instead of being passed on and moving the survey.
3384
[9ad92cc]3385* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]3386  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
3387  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]3388
3389* aven: Put a 5mm border around exported SVG files to allow for station markers
3390  and non-zero width lines.
3391
3392* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
3393  was turned on.
3394
3395* aven: Actually close the file we're exporting which fixes problems with it
3396  not always being fully written.
3397
[920b066]3398Changes in 1.1.7 (2005.10.18):
[6662d02]3399
3400* cavern: Add validity checking for dates in *date commands (with feature
3401  test in testsuite).  A date entered as just "year" or "year.month" now
3402  becomes a date range for the relevant period (previously it became a single
3403  date near the middle of that period).
[e0c7cd1]3404
[8add4c9]3405* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
3406  with MS Windows).
3407
[9f524ee]3408* extend: Default output name for a file called input.3d is now input_extend.3d
3409  rather than just extend.3d (which was annoying if you wanted to extend
3410  several surveys in the same directory).
3411
[185d793]3412* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]3413  our check for them to include that knowledge.
[185d793]3414
[3515947]3415* aven: Regenerate depth bar if user switches to/from metric units.
3416
[1235f9b]3417* aven: Don't clear the "there" mark just because the mouse pointer has
3418  moved off a station.
3419
[4299674]3420* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]3421  same directory (since that's where we then try to load it from).
[4299674]3422
[60dbe70]3423* aven: Fix labelling of date colouring on 32 bit platforms.
3424
[125c9ea]3425* aven: If "colour by date" is on and we load a survey with no date info
3426  (or all surveyed on the same date) then set "colour by none".
3427
[ec58e3d3]3428* aven: Make the error dialog modal and remove a signal handler once it
3429  has fired to prevent endless (or seemingly endless) cascades of error
3430  dialogs.
3431
[8add4c9]3432* aven: Enforce a minimum object volume diameter of 1m to avoid problems
3433  if a survey file with only one station in is loaded.
3434
[6662d02]3435* aven: Fix problems with indicators disappearing when we're drawing
3436  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]3437  introduced in 1.1.6).
[6662d02]3438
[b65c13f]3439* (Unix version): aven: Really stop setting extra toolbar margin when using
3440  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3441  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3442
[17cce5f]3443* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3444  we've been compiled with, and which GTK+/Motif version where appropriate.
3445
[affaeee]3446* (Unix version): Fixed build on Fedora Core 3.
3447
[618b01f]3448* documentation: Updates to 3d file format specification from Mike McCombe.
3449
[920b066]3450Changes in 1.1.6 (2005.10.10):
[7e01c87]3451
3452* (MS Windows version): Distribution is about a third smaller than 1.1.5
3453  (mostly because mingwm10.dll is no longer required).
3454
[b88b171]3455* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3456  it, showing cavern's output in a window (with errors and warnings clickable
3457  to load the offending file into an editor), and then loading the resulting
3458  3d file.
3459
[7e01c87]3460* aven: Added "Colour by Date" option.
3461
3462* aven: Disable "Colour by Depth" option if there's no elevation variation.
3463
3464* aven: Don't crash if trying to load a survey with no elevation variation.
3465  Instead turn off depth colouring.
3466
[8ea82aa]3467* aven: Export as HPGL added.
3468
[887c26e]3469* aven: Improved update of mouse coordinates and measuring line (thanks to
3470  Martin Green).
3471
[7c29c976]3472* aven: Show the coordinates of either the mouse pointer or the nearest
3473  survey station to it (if there is one near enough).  Showing both was
3474  confusing and meant the status bar overflowed on smaller displays.
3475
[7e01c87]3476* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]3477
[7e01c87]3478* aven: Don't lock "flat" surveys which aren't extended elevations - a
3479  flat survey with LRUD data isn't flat any more!
3480
3481* aven: When we have to draw blobs and crosses the slow way (because the
3482  graphics hardware doesn't support the fast way), draw them so that they
3483  should appear at the correct depth into the 3D scene instead of on top
3484  of everything else.
3485
3486* aven: Make "play presentation backwards" icon green to match the other
3487  presentation icons.
3488
3489* (MS Windows version): aven: Mouse clicks on the survey view now set the
3490  keyboard focus there.
[bd21214]3491
[b46bf92]3492* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3493
[796d7bf]3494* (MS Windows version): aven: Fix redrawing of measuring line.
3495
[7e01c87]3496* cavern: Store dates for img_XSECT.
3497
3498* cavern: Fixed small one-off memory leak if you specify -o more than once.
3499
[b88b171]3500* (Unix version): Check environmental variable LC_MESSAGES when deciding what
3501  language to use for messages.
3502
[7c29c976]3503* (MS Windows version): "Print" on a 3d file now prints through aven rather
3504  than the separate printer driver (Unix has done this for some time).
3505
[8ea82aa]3506* Removed old printer drivers.
3507
[7e01c87]3508* img library: When creating a 3d file, ignore img_XSECT if we've been asked
3509  to write a file format version which doesn't support it.
[8ea82aa]3510
[920b066]3511Changes in 1.1.5 (2005.09.20):
[106cfdf]3512
3513* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3514
[4ba80e0]3515* aven: Make blobs round like they are in Survex 1.0.
3516
3517* aven: If the graphics drivers don't support drawing blobs using OpenGL
3518  point markers, fall back to drawing filled circles.
3519
[95ce35f]3520* aven: If the graphics drivers support it, draw crosses as texture mapped
3521  OpenGL point markers which is much faster.
[90d0d71]3522
[95ce35f]3523* aven: Cross size increased to match Survex 1.0.
3524
[cd78148]3525* aven: We must update which blobs are displayed if display of surface or
3526  underground legs is toggled.
3527
[f5627353]3528* cavern: Fix handling of a *solve followed by survey data, none of which is
3529  attached to the previous data.
3530
[dfe4a520]3531* cavern: Fixed "No survey data" error when a *solve is followed by another
3532  *solve (or the implicit solve at the end of processing) with no data between
3533  them.
3534
[920b066]3535Changes in 1.1.4 (2005.09.19):
[4855072]3536
3537* aven: Added Aven's icon to the "About" dialog.
3538
3539* aven: Use localised character for the decimal point (e.g. "," in most
3540  continental European countries).
3541
3542* aven: Previously the survey tree would get focus and then take keypresses
3543  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
3544  operate on the cave, and transfer the input focus across when we do.
3545
3546* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3547
3548* aven: Speed up intialisation by delaying creation of OpenGL lists until
3549  they're needed.
3550
3551* aven: Added Mark Shinwell's bounding box with shadow of the survey.
3552
3553* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3554
3555* aven: Reworded "Restore Default Settings" as "Restore Default View".
3556
3557* (Unix version): aven: Set sensible default margins for printing and preserve
3558  any margin values the user specifies between runs (previously margins
3559  defaulted to 0 each time aven was run).
3560
3561* Documentation: Document *DATA PASSAGE in the manual.
3562
[920b066]3563Changes in 1.1.3 (2005.09.07):
[0e558e5]3564
3565* (Microsoft Windows version): Fixed build problems.
3566
3567* cavern: Allow OMIT character (-) for left/right/up/down.
3568
3569* aven: Remove an unnecessary menu separator.
3570
3571* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3572
3573* aven: Make the tooltip for "Hide" show the number of found stations.
3574
3575* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3576
3577* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3578  when there's a presentation loaded.
3579
3580* aven: Make entrances green in side panel tree list to match green blobs used
3581  in cave view.
3582
3583* aven: Don't show surface labels if we're not showing surface data, etc.
3584
3585* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3586  make "Space" the key for this.  Keep Return working "Stop Rotation" so
3587  existing users are happy, but don't advertise it.
3588
3589* aven: Normalise filename by adding any extension used, and use the normalised
3590  filename for file history and window title.
3591
3592* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3593  as the toolbar buttons already have a sensible margin - the extra margin is
3594  only needed with GTK1.2.
3595
3596* aven: Fix handling of plumb legs in tube model.
3597
3598* aven: Fixed swapped L and R in tube model.
3599
3600* extend: Preserve UD cross-section information in extended elevation.
3601
3602* extend: Add new messages for John Pybus' enhancements.
3603
3604Changes in 1.1.2 (never formally released):
[8faa5d8]3605
3606* Added support for LRUD data in .svx files, in .3d files, and aven can
3607  now load and display it on screen and on printouts.  The ability to "fake"
3608  LRUD data in aven is gone for now but will reappear in some form later.
3609
3610* cavern: Removed support for writing Chasm's 3dx format.  We're going to
3611  fold any desirable missing chasm functionality into aven.
3612
3613* aven: Rearranged mouse actions as discussed on the mailing list.  Added
3614  cursors for each different mouse action to help the user learn what each
3615  does.  Also added cursors for the "compass" and "clino" as well as the
3616  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]3617
[0e558e5]3618* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]3619
3620* tests/smoketest.tst: If X windows is running, check that we can run aven
3621  with --help and --version.
3622
3623* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3624  no results are listed for it.  This revealed that there was a "newline" test
[6225339]3625  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]3626  Fixed all these problems.
3627
3628* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3629  and omitted forward compass/clino readings in Compass DAT files.  Added
3630  a feature test for this to the testsuite.
3631
3632* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]3633  without OpenGL so remove old machinery for this from configure and the
3634  sources.
[8faa5d8]3635
[0e558e5]3636* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]3637
3638* configure: Better output for strcasecmp test.
3639
3640* aven: Fix crosses to work much better.  Not a total fix - their position
3641  in the Z buffer isn't correct and they're rather slow to plot.
3642
3643* aven: Don't regenerate the hittest grid every time the mouse moves while
3644  animating, which solves the mysterious pausing effect (thanks go to Martin
3645  Green for spotting this!)  Also clear all the status bar coordinates when
3646  animating.
3647
3648* aven: Sort out clashing menu shortcuts in some languages.
3649
3650* aven: Fixed compilation problem on x86_64
3651
3652* SPUD: Pruned out stuff which has been done or which is not actually relevant
3653  to this branch.
3654
3655* Merge various changes from 1.0 branch:
3656
3657  + aven: Port over "printing from aven" functionality.
3658
3659  + aven: Port over "export as" functionality,
3660
3661  + Add David Loeffler's vim mode for .svx files.
3662
3663* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]3664
[8faa5d8]3665* aven: Don't use an opengl list for drawing the indicators - we typically make
3666  a new list each time we plot them anyway.
3667
3668* Remove lingering traces of support for RISC OS and pre-386 MSDOS
3669
3670* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]3671  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]3672
3673* configure: Update wxWindows checks to handle newer wx versions.
3674
3675* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3676  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
3677  for anyone building from CVS).
3678
3679* acinclude.m4: Quote macro name for fix autotools warning.
3680
[4855072]3681* Documentation: "tilt up" is "'" not ",".
[8faa5d8]3682
3683* aven: Add support for mousewheels (to tilt the cave).
3684
3685* aven: Fixed twisted transitions to and from pitches in certain cases.
3686
[0e558e5]3687* aven: Pick a sensible initial window size when the user's desktop is spread
3688  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]3689  better with wx2.4 or earlier as well).
3690
3691* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3692  contents being visible before any survey is loaded.
3693
3694* aven: Allow a coloured texture to be used
3695
3696* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]3697  is default colour (grey for most systems) not black until a survey is
3698  loaded).
[8faa5d8]3699
3700* aven: Fixed weird "shadowed" icons.
3701
[920b066]3702Changes in 1.1.1 (2004-10-06):
[a7aa27d9]3703
3704* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]3705  startup.
[a7aa27d9]3706
3707* aven: Delay loading the bitmap for the "About" dialog until it is first
3708  needed.  We want start up to be as quick as possible.
3709
[920b066]3710Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]3711
[91e416e]3712* NOTE: Survex 1.1.X releases are development snapshots made available for
3713  the purposes of allowing wider testing and getting more user feedback.  Once
3714  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]3715
[91e416e]3716* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3717  you're using Windows 95 - these can be obtained from:
3718  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]3719
[91e416e]3720* aven: Solid passages - passage dimensions are currently inferred from
3721  the leg length (pretty effective as you can measure longer legs in
3722  larger passages).  Use of real LRUD data coming soon...
[edb6576]3723
[91e416e]3724* aven: Depth colouring is now continuously varying.
[edb6576]3725
[0580c6a]3726* aven: Colour by depth can now be turned off (and there's the start of a
3727  framework for properly implementing colour by date, error, etc).
3728
[4261983]3729* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3730  match (? matches any character, * matches any number of characters).
3731
3732* aven: We now use the status bar for coordinates, distances, etc to make
3733  better use of screen space.
[edb6576]3734
[f80077a]3735* aven: Full screen mode (F11).
[edb6576]3736
[6abab84]3737* aven: Perspective view.
3738
[91e416e]3739* aven: Context sensitive cursor shape - needs more work.
[edb6576]3740
[91e416e]3741* aven: Mouse actions changed (hopefully they're now more natural, but
3742  you may find the change disorientating - feedback wanted on this).
[edb6576]3743
[1690fa9]3744* aven: Added "presentations" which allow you to set up fly-through paths
3745  and load/save/run them.
3746
[0580c6a]3747* aven: A presentation can be exported as a movie file.
3748
[045e2af]3749* aven: Added Save screenshot facility.
3750
[c60062d]3751* aven: Depth fogging option.
3752
[0580c6a]3753* aven: Added Smooth Lines option.
3754
3755* aven: Added Textured Walls option.
3756
[f433fda]3757* aven: If a survey has surface legs but no underground legs, default to
3758  showing the surface legs.
3759
[0580c6a]3760* cavern: Dates given to *date are now stored in the 3d file.
