3Changes in 1.4.5 (2023-0?-??):
4
5* aven: Fix rendering of crosses when drawn as sprites.  Reported by echarlie.
6
7* (macOS version): aven: Fix crash in export dialog.  Fixes #133, reported by
8  rixyane.
9
10* manual: Expand docs on connecting to Compass data.
11
12* Minor translation updates.
13
14Changes in 1.4.4 (2023-02-03):
15
16* aven: Fix red line in clino background to be grey (this was introduced in
17  1.4.3 and was a debugging change accidentally left in).
18
19* aven: Accept weird .3d files from Therion which have empty components in
20  station names.  That's not really valid by Survex's definition of station
21  names, but it's not very helpful to reject such files, so just disable the
22  checks that were rejecting this.
23
24  The result is empty entries in the survey tree, but I don't see what we can
25  really do that's better than that.
26
27  Reported by Vasily Vl. Suhachev.
28
29* aven: Make it more obvious you can enter a custom scale by adding a "..."
30  entry to the scale combobox - selecting this clears the value and gives focus
31  to the combo box text entry. This control has always supported clicking to
32  enter a custom scale, but there wasn't really any indication that this was
33  possible before.  Partly addresses #132, reported by Eric C. Landgraf.
34
35* aven: Force export window to resize when the export format is changed as
36  different controls are shown depending on the export format.
37
38* aven: Right-align tilt spin control value in print/export dialog to match the
39  bearing spin control.
40
41* aven,survexport: Add ability to export as Survex 3d which is useful as you
42  can filter to a subset of surveys, filter out splays, convert from other
43  formats the img library can read, etc.  This feature is a bit rough and ready
44  currently but please report issues.
45
46* dump3d: Add --legs option which converts MOVE and LINE to a single LEG line
47  per leg with the from and to coordinates.  Tools which parse dump3d output
48  should find this easier to process as it avoids having to track a "current
49  position".
50
51* Update manual to have a complete list of quantities which *calibrate accepts.
52  Reported by echarlie
53
54* cavern.tst: Fix testsuite to work with SOURCE_DATE_EPOCH set.
55
56Changes in 1.4.3 (2022-05-17):
57
58* aven: Much improved support for HiDPI monitors on all platforms.
59
60* aven: When started without a file make sure the window has focus so menu
61  accelerators and shortcuts work without clicking on the window.
62
63* aven,survexport: DXF export now puts splays in a separate layer and uses a
64  dotted linetype for them.  Patch from echarlie, see #60.
65
66* Improved survexport man page to include command line options and a short
67  note about DXF export.  Patch from echarlie.
68
69* Minor translation updates.
70
71* (Unix version): aven: Fix handling of EGL-based wxGLCanvas (which wxGTK 3.1.5
72  has).  Fix a build failure and don't force X11 (as the EGL-based wxGLCanvas
73  works on Wayland).
74
75* (MacOS version): aven: Fix hang on startup without a file.  Fixes #120,
76  reported by Enrico Fratnik.
77
78* (Microsoft Windows version): Now using wxWidgets 3.1.6 (was 3.0.5).
79
80* img library: Support reproducible builds which create .3d files by not
81  embedding a timestamp if environment variable SOURCE_DATE_EPOCH is set.
82  Requested by Martin Budaj.
83
84Changes in 1.4.2 (2022-02-25):
85
86* aven: Fix to be compatible with FFmpeg 5.0.
87
88* Improve docs for *cs and *declination.
89
90* cavern: Fix "*declination auto" not to crash when built with PROJ < 8.1.0.
91  Bug introduced in 1.4.0.
92
93* cavern: For each `*declination auto` command cavern now reports an "info"
94  message showing the range of calculated declination values and the dates at
95  which the ends of the range were obtained, and also the grid convergence
96  (which doesn't vary with time).  Fixes #92, reported by Rob Eavis.
97
98* cavern: If any of the N-S, E-W or U-D ranges includes an anonymous station
99  then also report the range in that direction excluding anonymous stations.
100  Patch from Thomas Holder.
101
102* cavern: The error from a bad `*cs custom` command now highlights the quoted
103  string properly.
104
105* cavern: "FIX command with no coordinates - fixing at (0,0,0)" is now an
106  "info" rather than a "warning".  It's not really reporting a problem and the
107  ability to omit the coordinates is a deliberate feature.  It is useful for
108  the user to know where the "*fix" without coordinates is if they want to
109  change the survey to be in real coordinates, so an "info" diagnostic is a
110  good fit.  This also means aven will no longer stay on the log view after
111  processing a dataset which fixes without coordinates.
112
113* cavern: If "*fix" is used twice with no coordinates we no longer say
114  "FIX command with no coordinates - fixing at (0,0,0)" right before:
115
116  error: Already had FIX command with no coordinates for station "x"
117
118* cavern: Include errors in Compass .mak files now report the error in the line
119  where the included filename is actually specified.
120
121* cavern.tst: Add test coverage for warnings for *entrance and *export with
122  a station which doesn't exist otherwise.
123
124* aven/survexport: Change JSON export to be valid JSON.  This means the output
125  has changed incompatibly, but it wasn't valid JSON before which suggests
126  nobody was actually successfully using it. Fixes #128, reported by Pawczak.
127
128* aven.tst: Skip one testcase on macos as it seems to hang, at least when
129  running on the Continuous Integration system.
130
131* (Microsoft Windows version): The installer is now generated with a much
132  newer version of Innosetup.  Most notably, it now supports installing as a
133  non-admin user.  This also means Microsoft Windows Vista is now the minimum
134  supported version but 2000 and XP are both many years out of support anyway.
135
136* (Microsoft Windows version): The coordinate system database for PROJ is
137  now included so "*cs" now works (broken since 1.4.0).
138
139* Chinese translation updates from Qingqing Li.
140
141* Building from source now requires a compiler with support for C99.  C99
142  seems to be universally supported by compilers now so we don't expect this to
143  inconvenience anyone.
144
145Changes in 1.4.1 (2021-11-08):
146
147* This release should work with any PROJ version >= 6.2.0.
148
149* cavern.tst: Fix to actually run tests when building outside the source
150  tree.  Previously files for testcases weren't found, and tests were skipped
151  with a warning, which lead to 1.4.0 being released with two failing testcase.
152  Fix to find the files, and make not finding them an error.
153
154* cavern.tst: Fix testcases gpxexport and require_fail which were failing
155  in 1.4.0.
156
157* 3dformat.htm: Document that coordinate system can be ESRI:<number>.
158
159Changes in 1.4.0 (2021-11-06):
160
161* New release series to mark that Survex now uses the new PROJ API, and
162  requires PROJ >= 7.2.0.  Survex 1.2.x will continue to support PROJ < 8
163  (and won't support newer PROJ versions).  Fixes #102, reported by Bas
164  Couwenberg.
165
166  Due to these changes, PROJ will now convert directly between coordinate
167  systems where it knows how to, instead of always converting via WGS84.
168  This means conversions may now be more accurate in some cases, and you may
169  notice station coordinates changing - these should be for the better.
170
171  Also, the vertical datum is now taken into account automatically, and
172  terrain data now aligns much better vertically with surveys.  Fixes #56.
173
174* aven: Clicking and holding the left mouse button on the compass or clino,
175  then (while still holding) clicking the right button no longer causes a
176  wxWidgets assertion to fail.  Reported by echarlie.
177
178* img library: Rewrite certain proj strings when reading 3d files for
179  better compatibility with newer PROJ versions, where use of proj
180  strings is strongly discouraged.
181
182  `+init=epsg:` followed by a code number is rewritten to `EPSG:`.
183
184  `+init=esri:` followed by a code number is rewritten to `ESRI:`.
185
186  The proj strings which cavern used to put in 3d files for UTM zones and
187  S-MERC are rewritten to `EPSG:` follow by the appropriate code number.
188
189* Also install survex.lang for gtksourceview 4. Fixes #125, reported by Martin
190  Green.
191
192* Fix missing data style in interleaved example in manual.  Reported by
193  echarlie.
194
195* Use jw from docbook-utils instead of sgmltools-lite to process the manual.
196  The sgmltools-lite homepage says it's no longer being developed, and suggests
197  docbook-tools (which Debian packages as docbook-utils) as a replacement.
198
199* doc/HACKING.htm: Update Debian packages to install
200
201* doc/HACKING.htm: Update details of setting up mingw cross-build environment.
202
203* Add simple tests for GPX and KML export.
204
205* Expand cavern testcase csbad.
206
207* cavern.tst: Parse warning/error counts more robustly.  Previously we'd get
208  confused if the final line just contained an integer, e.g. if we end listing
209  stations not attached to a fixed point.
210
211Changes in 1.2.45 (2021-03-09):
212
213* Avoid undefined signed shifts in 3d file handling.  Survex itself is only
214  affected on big-endian platforms (so most Linux machine, Microsoft Windows,
215  and current Macs are all OK), but this also affects the img library on all
216  platforms when used in standalone mode as it is in other programs.  Fixes
217  #119, reported by Matěj Plch.
218
219* aven:
220
221  + When reading cavern output for the log window, we need special handling
222    for the case when a chunk of output ends mid-way through a UTF-8
223    sequence.  Previously we lost the first byte of the sequence in this
224    case (and would then show it as an invalid character), but now it is
225    handled correctly.  In practice, most of the cavern log output is ASCII so
226    it's quite possible nobody's ever actually hit this.
227
228* testsuite:
229
230  + Suppress reports of leaks on exit from the LeakSanitiser debugging tool.
231    We know we don't release all memory explicitly on exit since doing so would
232    mean extra work for no reason as the OS reclaims all memory when the
233    process exits.
234
235* Convert OLDNEWS encoding from ISO-8859-1 to UTF-8.
236
237Changes in 1.2.44 (2021-02-10):
238
239* aven:
240
241  + (Microsoft Windows version): Now using wxWidgets 3.0.5 (was 3.0.4).
242
243* cavern:
244
245  * Add support for quadrant bearings (e.g. N30E).  Patch from echarlie.
246
247  * Report error if angle units are specified for passage dimension.
248    Previously "*units left degrees" and similar were incorrectly quietly
249    accepted.  Spotted by echarlie.
250
251  * Fix *data with no parameters to keep the current style and reset any state
252    as documented.  Previously it actually instead ignored any survey data
253    until the next *data command with parameters.
254
255  * Fix minor memory leak in *data.  We leaked a single memory allocation on
256    "*data default" or an invalid *data command.
257
258  * Improve test coverage.
259
260* survexport:
261
262  * The check for whether a format supported --elevation, --plan, --bearing and
263    --tilt was inverted.  Reported by echarlie.
264
265  * Fix reporting of export errors on Microsoft Windows.  Reported by Matic Di
266    Batista.
267
268* img library: Fix img_open() when used in other programs.  Patch from Thomas
269  Holder.
270
271* configure: Add wx-config-gtk3 to WX_CONFIG search for Arch Linux.  Patch
272  from Thomas Holder.
273
274* Improve documentation of interleaved data.  Most notably, we now document
275  that a blank line breaks the current traverse.
276
277* Fix typo in manual ('cypolar' -> 'cylpolar').  Patch from Wookey, fixes #117.
278
279* Chinese translation updates from Qingqing Li.
280
281* Russian translation updates from Vasily Vl. Suhachev.
282
283* French translation updates from Jean-Marc and from Wassil Janssen.
284
285* Bulgarian translation updates from Wassil Janssen
286
287Changes in 1.2.43 (2020-02-28):
288
289* cavern: Update to use v13 of the IGRF model for calculating declinations.
290  This was issued in December 2019 and should give slightly more accurate
291  declinations for surveys made since 2010.
292
293* aven:
294
295  + Fix colouring of "not in loop" when colouring by error.  1.2.42 introduced
296    a bug where surveys not in a loop were coloured as if they had zero error.
297    Fixes #111, reported by Bruce Mutton.
298
299  + Fix handling of grid in export.  The grid was always getting enabled
300    (probably since 1.2.8) even for formats which don't support exporting with
301    a grid.  This resulted in the bounding box being set wrongly for some
302    formats such as SVG, as reported by Richard Knapp on the mailing list.
303
304  + When showing errors processing the survey data we'd previously crash if
305    cavern incorrectly reported an error as being in a column off the end of
306    the line - now we just ignore the error column in this case.
307
308  + Support colouring by survey style ("normal", "diving", "nosurvey", etc).
309
310Changes in 1.2.42 (2019-09-04):
311
312* aven:
313
314  + Allow colouring by horizontal or vertical error.
315
316  + (Unix version): Disable scaling for HiDPI displays with GTK3.  The OpenGL
317    code needs work before this will work usefully, so just disable for now
318    (which simulates how things are when using GTK2).
319
320  + (Unix version): Fix orientation of notebook tabs when build with wxWidgets
321    3.1 development versions.  We want horizontal tab orientation, but were
322    passing a weird flag combination which now results in vertical tab
323    orientation.
324
325* When exporting to a format where we support rotation in the horizontal
326  plane (such as SVG), the rotation was incorrectly applied to cross section
327  data (except for the default rotation of zero).  Fixes #108, reported by
328  Richard Knapp.
329
330* Add a section to the manual covering the command line tools, and what you
331  might still need to use them for.
332
333* Fix compiler warning when building from source with GCC 9.
334
335* Consistently refer to macOS not OS X - Apple have renamed it yet again.
336
337* (macOS version): Revert the workaround for the crash on macOS 10.14.  The
338  bug we were working around is fixed in git ready for wxWidgets 3.0.5 and
339  there's a backported fix in the homebrew wxmac 3.0.4-2 package, which is how
340  we now recommend people install on a Mac.  Closes #101, reported by floho.
341
342* (macOS version): Remove buildmacosx.sh script since installing from homebrew
343  is now the recommended approach.
344
345Changes in 1.2.41 (2019-07-10):
346
347* aven:
348
349  + (Microsoft Windows version): Fix error on startup in the pre-built version
350    of 1.2.39 and 1.2.40.  This is a recurrence of the same issue as affected
351    1.2.33 - this time I've patched out the unnecessary check in wxWidgets
352    which causes this problem so it shouldn't recur again.  Reported by
353    Brian Clipstone.
354
355  + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
356    as I don't have access to a Mac).  Hopefully fixed #101, reported by floho.
357
358Changes in 1.2.40 (2019-07-04):
359
360* aven: Draw the measuring line ring with an even shape.  Previously the exact
361  shape of the ring varied slightly depending on the exact coordinates, which
362  could be visually distracting once you noticed it.
363
364* We were casting a function pointer with a bool return type to the same type
365  but with a void return type.  In practice this probably works fine on most
366  platforms, but it's undefined behaviour and also gives a compiler warning
367  with some compilers.
368
369* Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
370  installed.
371
372Changes in 1.2.39 (2019-06-29):
373
374* Support versions 5.x and 6.x of the PROJ library we use for handling
375  conversions between coordinate systems.  Reported by Bas Couwenberg
376  in #102, by Richard Knapp in #103 and by Martin Sluka in email.
377
378* (Unix and Mac OS versions): When checking if something is a file or if it is
379  a directory, we no longer treat a symlink as being neither, but instead
380  return an answer based on what the symlink points to.
381
382* aven:
383
384  + Improve handling of hidden splay ends.  Previously, hidden splay ends still
385    served as "targets" for snapping the mouse pointer to, and still got
386    crosses when crosses were enabled.  We don't have a handy flag for "this is
387    the outer end of a splay" and computing that on demand isn't so easy to do,
388    so for now we use the "anonymous station" flag so at least these cases now
389    behave properly for splays to anonymous stations (which is likely to be
390    what people with huge numbers of splays from disto-x, etc are using).  This
391    does mean that anonymous stations on continuation passages will incorrectly
392    also be off when splays are hidden, but that seems an OK trade-off for now
393    and a definite improvement over the previous situation.  The snapping of
394    the mouse pointer was reported by Frank Tully in #105.
395
396  + Fix typo in export UI (CVS should be CSV).
397
398* Documentation:
399
400  + Add CSV to documented list of survexport output formats.
401
402  + Fix *declination syntax synopsis - "auto" is a literal string, not a
403    placeholder.
404
405  + Update PROJ project name and website - the name is now "PROJ" (all caps and
406    no ".4" suffix) and the website is now: https://proj.org/
407
408* Install gtksourceview-3.0 language file so .svx files now get syntax
409  highlighting in gedit and other GtkSourceView-based editors.  Patch
410  from Philip Withnall.  Fixes #98.
411
412* (Microsoft Windows version): The Survex installer doesn't uninstall the old
413  version when you upgrade, but just overwrites it with the new version.  In
414  1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
415  an older version would still have cad3d.exe from that old version.  We now
416  remove any old cad3d.exe left over from a previous install in the same
417  location to avoid confusion.
418
419* Add a few more message translations.
420
421* Fix warnings when built with a C++11 compiler.
422
423Changes in 1.2.38 (2019-03-02):
424
425* cavern:
426
427  + Deprecate MILS as angular units.  Survex has long support MILS as an alias
428    for GRADS.  However, this seems to be a bogus definition of a "mil" which
429    is unique to Survex (except that Therion has since copied it) - there are
430    several different definitions of a "mil" but they vary from 6000 to 6400 in
431    a full circle, not 400.  Reported by Andy Edwards.
432
433  + Fix segfault for *include "".  This isn't useful, but shouldn't crash.  It
434    now reports "file not found" instead.
435
436  + Use isnan() to check for not-a-number.  This is cleaner, more robust and
437    more efficient than formatting the number as a string and checking for
438    "NaN" or "nan" in the result.
439
440* Avoid unused variable warning when compiling from source with modern ffmpeg.
441
442* Drop support for wxWidgets < 3.0.  3.0.0 was released over 5 years ago and
443  should be easily available everywhere by now.  I'm no longer easily able to
444  test with wxWidgets 2.8, and this allows a significant amount of cruft to be
445  removed.
446
447* (Linux version): survex.spec: Fedora have removed gcc from the default build
448  environment so need to explicitly list it in the BuildRequires tag.  See
449  https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
450  information.  Patch from James Begley.
451
452Changes in 1.2.37 (2018-11-18):
453
454* aven:
455
456  + Add basic "Colour by Survey" feature.  The colours used aren't currently
457    controllable.
458
459  + Fix export of splays.  Patch from Thomas Holder.
460
461  + Fix KML export to avoid invalid geometry when a tube intersects itself.
462    Patch from Robert Jones.
463
464  + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
465    for now.  This is a workaround until wxWidgets OpenGL support is updated
466    to work under Wayland.  Reported by Philip Balister.
467
468  + Fix warnings about using deprecated functions when building movie export
469    code using FFmpeg 4.0.
470
471* cavern:
472
473  + Compass MAK files: Handle fixed point coordinates in feet - previously the
474    units were ignored and the coordinates assumed to be in metres.
475
476  + Previously the first byte in a MAK file was ignored.  Typically MAK files
477    start with a comment, and since cavern currently ignores lines that start
478    with characters it doesn't understand the meaning of, this bug would often
479    go unnoticed.
480
481* survexport:
482
483  + Fix exporting of passages, walls and cross-sections by running the code
484    aven uses to decide how much to rotate each cross-section.  Previously all
485    cross-sections were aligned West-East.  Reported by Robert Jones.
486
487  + Default to .pos output if the program name is 3dtopos, and install a second
488    copy (or hardlink under Unix) as 3dtopos.  This provides compatibility with
489    current releases of Tunnel.  Reported by Becka Lawson, Wookey and
490    Stephen Crabtree.
491
492* Fix some German translations.  Patch from Thomas Holder.
493
494* (MacOS X version): Fix aven-create-app to not delete converted icons.
495  Typo spotted by Robert Jones.
496
497* Improve documentation for *team.  Document the requirement to quote names
498  unless a person is identified by just one name.  Document that the roles are
499  optional, as that information may not have been recorded, and to align with
500  therion's team command.
501
502Changes in 1.2.36 (2018-07-18):
503
504* aven:
505
506  + Add support for exporting as a CSV (Comma-Separated Values) file.
507
508  + Support exporting KML with altitude mode "clamp to ground".  In this mode,
509    the altitude in the data is ignored and it's rendered on the surface of the
510    terrain.  This is useful if your KML viewer renders the terrain as opaque
511    so underground data isn't visible.  Rendering cave passages on the surface
512    isn't great, but is better than not being able to see them at all.  This
513    option may also be helpful if you want to see where to look on the surface
514    for new entrances.
515
516  + Highlight surveys with a white loop as the mouse is moved over them in
517    the survey tree.  This is akin to how we highlight a station with a
518    white ring, and allows restoring "double-click survey in tree to zoom"
519    which temporarily required a quadruple-click in 1.2.35.
520
521  + Only show checkboxes in the survey tree for surveys not stations.
522
523  + Fix wxWidgets assertion if the user tried to select additional surveys
524    to show via the right-click menu.
525
526  + Fix multiple survey filtering when both a parent and child survey are
527    selected.  In this case it makes most sense to show all child surveys of
528    the parent, but we actually showed a slightly arbitrary subset of the
529    child surveys of the parent.
530
531  + The checkbox area in the survey tree is now included in the area which
532    is considered by mouse-over updates such as highlighting the station or
533    survey.
534
535  + Fix display of double quotes in cavern log window (they were being replaced
536    with control character 0x16 due to a typo in the code).
537
538  + Add shortcuts to buttons in cavern log window.
539
540  + Eliminate use of gluErrorString() function which eliminates some
541    deprecation warnings when building on macOS.
542
543  + Reject multiple --survey command line options for now (only the last has
544    been used for a long time, but now we actually support multiple survey
545    filtering this matters more).
546
547* survexport:
548
549  + Report a useful error when trying to convert a .3d file without coordinate
550    system information to GPS.  Reported by Mark Shinwell.
551
552  + Handle multiple redundant --survey command line options correctly.
553
554* dump3d: Report station flag "WALL", which was added in 1.2.7.
555
556* Minor translation updates.
557
558* Update manual for Microsoft Windows changes.
559
560* tests/: Add test coverage for warnings about suspect readings
561
562* Fix warning when compiling with clang.
563
564Changes in 1.2.35 (2018-07-03):
565
566* aven:
567
568  + Viewing can now be restricted to multiple surveys.  Use the right-button
569    menu on a survey in the survey tree and select "Show" to enable checkboxes
570    for that survey and all its siblings.  Only the selected surveys are shown
571    on screen, printed and exported.
572
573  + Don't open a survey when its name is double clicked.  This was happening
574    due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
575    However, reverting that change still seems to allow double-clicking to work
576    on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
577    survey.
578
579  + Pick initial survey scaling based on whichever of the window width or
580    height gives the smaller scale.  Previously we always used the window
581    width, which can result in parts of the cave being outside the initial
582    view.  Reported by Wookey.
583
584  + Drop ability to specify a PROJ string in the export dialog.  This was added
585    to allow exporting to formats such as GPX before we added support for
586    specifying the projection in .svx files, and that support is now mature.
587
588  + DXF export now uses 2 decimal places (was 6) for the bounding box, for
589    consistency with the precision used for coordinates.
590
591  + Fix handling of surface flag during export.  In formats which discriminate,
592    legs could previously have got assigned the wrong status.
593
594  + Fix bug which probably prevented aven starting when OpenGL double buffering
595    is unavailable.  This is unlikely to affect any common configurations.
596
597  + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
598    filenames.  Issue reported by Matic.
599
600  + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
601    Probably broken since 1.2.17.
602
603* survexport: New command-line export program which uses aven's export code.
604  Replaces 3dtopos, cad3d and findentrances, since it can do all that these
605  tools could do, plus much more.
606
607* Merge more Spanish i18n updates from Evaristo Quiroga.
608
609* Minor updates to various other translations.
610
611* img library:
612
613  + Now supports reading from and writing to an existing FILE*.
614
615  + Improve API documentation.
616
617* (Microsoft Windows version): Fix packaging to include wxWidgets translation
618  files like it was supposed to, which fixes a few missing translations.  This
619  was probably broken by changes in 1.2.8.  Reported by Evaristo Quiroga.
620
621* (Microsoft Windows version): Drop two options from explorer bindings.
622  "Convert to DXF" and "Convert for hand plotting" have both been supported via
623  aven for a while, and that's a more useful way to access them as you can
624  control what gets exported.
625
626Changes in 1.2.34 (2018-03-24):
627
628* aven:
629
630  + (Microsoft Windows version): Fix error on startup in the pre-built version
631    of 1.2.33.
632
633  + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
634
635Changes in 1.2.33 (2018-03-22):
636
637* aven:
638
639  + Reliably disable scale bar in perspective view.  This is supposed to happen
640    (because the scale across the screen varies in perspective view) but
641    actually the scale bar stayed around until an update was forced for another
642    reason.  Spotted thanks to Pedro Silva Pinto.
643
644  + Make "no date"/"not in loop" colour grey.  The white was a bit bright and
645    made it harder to see the legs that had colours.  The grey now used is
646    within the brightness range of the other colours.  Fixes #94, reported by
647    Erin Lynch.
648
649  + Fix KML export - exporting both survey legs and station names resulted in a
650    malformed KML file.  This bug was introduced in 1.2.30 when support for
651    exporting passages and walls was added.  Reported by Erin Lynch in #90.
652
653  + Consistently use 2 decimal places for altitude in KML output.  Some places
654    used 8 decimal places which is appropriate for lat and long, but clearly
655    overkill for an altitude in metres and increases the file size
656    unnecessarily.
657
658  + Right-align bearing widget in print/export dialog.  The change to allow the
659    value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
660    left-aligned (due to incorrect wxWidgets documentation of the default style
661    for this control).
662
663  + (Unix version): Work around wxWidgets bug so that custom cursors work
664    under GTK3.
665
666  + (Unix version): Update GTK version reporting - report GTK3, and don't
667    bother to report subversions of GTK2 (it seems to be fairly arbitrary
668    which subversions wxWidgets defines constants for).
669
670  + Update code to work without warnings when using wxWidgets 3.1.0 (the
671    current development version).
672
673  + Make movie export code compatible with upcoming FFmpeg 3.5 release.
674    It should still work with the older versions that worked before this
675    change.  Reported by James Cowgill in https://bugs.debian.org/888334
676
677* cavern:
678
679  + Warn about 2 digit years.  We can't change the assumption that these are
680    19xx without risking breaking existing datasets, but the further we get
681    into this century, the more likely such an assumption is to catch someone
682    out.  The warning can easily be quashed by explicitly adding the assumed
683    "19".
684
685* The Spanish translation is now up to date once more, thanks to updates from
686  Evaristo Quiroga.
687
688* Merge French translation updates from Jean-Marc.
689
690* Fix transposed German Northing and Easting labels.  Fixes #95, reported by
691  milosch.
692
693* Fill in missing translations of "Easting", "Northing", "E" and "N" for
694  Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
695  translated messages.
696
697* Align .pos file headings better with columns of coordinates below for
698  Indonesian and Polish.
699
700* Fix handling of the message string "error" before messages loaded.  If
701  there's an error loading messages, we need this message to report it.
702  Reported by Martin Sluka.
703
704* Fix a few compiler warnings.
705
706* img library: Fix extracting leaf survey name for survey title.  When there
707  are three or more levels of survey, we were taking everything after the first
708  dot rather than everything after the last dot.
709
710* Fix problems with testsuite on macOS:
711
712  + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
713    - this test isn't meaningful unless the filing system is case-sensitive,
714    but happens to fail if it isn't.
715
716  + cavern.tst: Workaround limitations of Apple's sed.
717
718  + aven.tst: Fix not to hang on macOS.
719
720  + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
721
722* Clean up handling of support files in relocatable installs - this is now
723  detected at run time on macOS.
724
725* Split out macOS Aven.app creation into a make rule so it can be easily used
726  by the homebrew formula.
727
728* buildmacosx.sh:
729
730  + Fix when WX_CONFIG not specified - this was giving a confusing error like:
731    ./buildmacosx.sh: line 163: --cc: command not found
732
733  + Use wxWidgets 3.0.4.
734
735* Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
736  and we currently require 2.8 or newer.
737
738Changes in 1.2.32 (2017-07-08):
739
740* aven:
741
742  + Make splays on printouts a darker shade of grey.  Reported by Erin Lynch
743    and Anthony Day.
744
745  + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
746    POS), the value in the Z dimension was negated.  Bug introduced by fixes
747    for export of rotated plans and tilted elevations in 1.2.27.  Reported by
748    Erin Lynch in #89.
749
750  + Ignore viewing angles for export formats which work in 3D.  When the
751    rotation and tilt controls are hidden in the export dialog we were still
752    using their values to transform the data, so if you set them with for one
753    export format which support them, then switched to an export format which
754    doesn't, you'd get bogus coordinates in the exported file.  Bug probably
755    introduced in 1.2.27 by fixes for exports of rotated plans and tilted
756    elevations.
757
758  + Fix exporting to skencil and Survex .pos formats.  When aven's export to
759    .pos was added in 1.2.19, the ordering didn't match up and since then .pos
760    export has produced skencil files and vice versa.
761
762  + Don't leave terrain on if loading terrain data fails.  Previously if you
763    clicked the terrain icon (or via the menu) with no terrain loaded, but no
764    terrain got loaded (e.g. because the survey data lacks an explicit
765    coordinate system, or because the file failed to load, or because you
766    cancelled the dialog) then the terrain icon/menu item was still changed to
767    "on".
768
769  + Disable texturing while drawing terrain.  Previously the terrain got a bit
770    darker when "Textured Walls" were enabled.
771
772  + Force a refresh when "Textured Walls" are enabled or disabled.  Previously
773    the display wouldn't update right away.
774
775* Manual:
776
777  + Document how to specify fixed point altitude in feet.
778
779  + Explain why *fix warns about unused fixed points
780
781* Building from source now requires a compiler with decent support for C++11.
782  If you're using GCC, then GCC 4.7 should suffice.  This should not be an
783  onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
784  enough GCC.  If special options are needed, these should get probed for and
785  automatically.  Fixes building 1.2.31 with GCC < 6, reported by Wookey.
786
787Changes in 1.2.31 (2017-07-01):
788
789* aven:
790
791  + Use superscript 'g' symbol instead of word 'grads' in status bar.  This
792    conserves the limited space available, and we already do this in the
793    compass and clino indicators so it's more consistent too.
794
795  + Show one decimal place on measure line bearing.  Pointed out by Benedikt
796    Hallinger on the therion list, though I'm sure this has been asked for
797    before by others.
798
799  + Show gradient of the measuring line when both ends are stations.
800
801  + Allow selection of text in cavern log window.  Selection was disabled in
802    1.2.28 because it seemed you couldn't actually copy selected text to the
803    clipboard, but retesting this now actually works fine for me, both with
804    current git master with the change reverted, and with code just before the
805    original change.
806
807  + More robust parsing of cavern output (cleanly handle context highlighting
808    which extends beyond the end of the line).
809
810  + Allow showing duplicate legs as dashed lines or hiding them entirely,
811    with dashed now being the default.  Implemented by Patrick Warren.
812
813  + Also allow "Dashed" for splays and "Faded" for duplicate legs.
814
815  + Splay legs in surface data are also shown faded.
816
817  + Check environment variables VISUAL and EDITOR when looking for editor to
818    use when a warning or error is clicked on in the cavern log window.  The
819    specified editor may have a GUI or need to run in a terminal, so we have to
820    special-case each editor supported, and that means we can pass extra
821    options needed to position the cursor on the appropriate line/column.
822    Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
823    emacs, nano, jed, kate.  Suggested by Wookey.
824
825  + Fix handling of non-square terrain data files - the X and Y dimensions were
826    swapped.  Reported by detrito.
827
828  + Improve parsing of DEM data with .hdr file.  Use documented defaults for
829    more values, and where we only support a subset of values (or a particular
830    value) check for unsupported values in more cases.
831
832  + When colouring by depth, fix colouring and texturing of polygons which
833    cross depth bands.  The previous problems were most obvious with high
834    chambers and long legs down deep pitches, especially in for surveys without
835    much vertical range.
836
837  + Support for drawing blobs using point sprites was added in 1.2.28,
838    but caching that this worked wasn't hooked up properly so the test to
839    see if this worked would happen at the start of each run.  This is now
840    cached as intended which should reduce start up time a little when blobs
841    are drawn in this way.
842
843  + Fix drawing of crosses with lines.  This is a fall-back case which is
844    rarely used as most OpenGL setups will handle a better method, but it was
845    resulting in crosses with a four-pixel square in the centre - now the
846    centre should be a single pixel.
847
848* cavern:
849
850  + Allow *data with no arguments to reset the current style - useful for
851    entering passage data where there are side passages.
852
853  + Fix hang processing file without newline at end.  This bug was introduced
854    by changes in 1.2.28.  Reported by Mark Brown.
855
856  + (Mac OS X and Microsoft Windows versions): Build with newer version of
857    PROJ library which fixes buggy handling of *fix with lat-long coordinates.
858    Also add a testcase to the testsuite to alert users building for themselves
859    with an affected PROJ version on any platform.  Reported by Ross Davidson.
860
861  + Fix cavern to handle Compass .DAT with no survey team.  Previously this
862    resulted in the bogus error: Expecting numeric field, found "FROM"
863    Reported by Erin Lynch.
864
865  + Handle UTF-8 "BOM" at start of .svx files.  Unicode doesn't recommend its
866    use, but Microsoft stuff seems to like to create files with it in, and the
867    error cavern currently reports for such files is very confusing, so it
868    seems best to just handle it.  Reported by Rob Eavis.
869
870  + Change a couple of messages to use double quotes for consistency with all
871    other messages.
872
873* extend:
874
875  + Now runs a bit faster.
876
877  + Splays are now carried over the extended survey.  The current handling
878    is simplistic, but should do a good enough job to be more useful than
879    discarding splays.  The splays at each station are all rotated together
880    based on the bearing between the stations either side of the current one
881    along the first path extended through that station.  This nicely handles
882    dead ends and the situation at the top or bottom of a pitch, and should
883    tend to pick an angle close to the passage orientation along a traverse.
884    It's weakest at junctions.  Feedback (especially examples which could
885    be handled better) most welcome.
886
887* French translation is now up to date again, thanks to Jean-Marc.
888
889* Remove erroneous menu shortcut markers from Polish translations.
890
891* Fill in some missing translations in several languages by using message
892  translations from therion.
893
894* Add note to *fix documentation to clarify the coordinate order with *cs
895  long-lat.  Issue raised by Ross Davidson.
896
897* Fix errors in documentation of *units: "DEG" should be "DEGS", and
898  "MINUTES" has been supported for ages but wasn't documented.  Reported by
899  Footleg.
900
901* Fix a few typos in the documentation.
902
903* Fix compilation warning with recent GCC.
904
905Changes in 1.2.30 (2016-10-03):
906
907* aven:
908
909  + (Microsoft Windows version): Fix crash when trying to print or export
910    (probably introduced in 1.2.28).  Reported by Brian Clipstone.
911
912  + Report error if terrain file contains no terrain data in area of survey.
913    Suggested by detrito.
914
915  + Errors when writing an export file were reported with the wrong filename
916    - the .3d file, not the filename we were trying to write to.
917
918  + Export to KML now supports exporting passages, walls and cross-sections.
919    Addresses the remainder of ticket #4.
920
921* Add man page for dump3d.
922
923Changes in 1.2.29 (2016-09-27):
924
925* aven:
926
927  + Fix SVG output with non-ASCII characters (the charset in the SVG file
928    is now set to UTF-8 not ISO-8859-1).
929
930  + (Microsoft Windows version): Fix error dialog on startup in pre-built
931    version.  Reported by Brian Clipstone.
932
933* Manual: Add link to TerrainData wiki page.  Omission highlighted by Erin
934  Lynch and "detrito".
935
936* Fix to build without FFmpeg/libav and with older versions, broken by changes
937  in 1.2.28.  Reported by James Begley.
938
939Changes in 1.2.28 (2016-09-24):
940
941* cavern:
942
943  + Show the contents of the line after error and warning messages while
944    processing survey data, and indicate the region of the line in many cases
945    in the same style that compilers such as GCC and clang use (using the
946    column number we already have, plus new width information).  Based on a
947    patch from Mateusz Golicz.
948
949  + Add column and width information for many more error and warning messages.
950
951  + Fix column for "Separator in survey name" warning.
952
953  + Improve warnings when using a backclino with range 0-180 degrees (reusing
954    the same machinery we already have for a forward clino with range 0-180
955    degrees).
956
957* aven:
958
959  + Include LRUD in printout/export of extended elevations, broken by
960    improvements to export of tilted elevations in 1.2.27.  Reported by Anthony
961    Day.
962
963  + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
964    usefully.  Reported by Anthony Day.
965
966  + Remember scale from previous print or export operation in the same run of
967    aven.  Suggested by Stuart Bennett.
968
969  + Convert range indication below shown line to a highlight on that region
970    of the line in cavern log window.
971
972  + Fix colouring of error/warning without column in cavern log window.
973
974  + Fix click on error/warning without column in cavern log window.
975
976  + Fix highlight of translations of "error" or "warning" containing non-ASCII
977    characters.  This fix for this only works with a Unicode build of
978    wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
979    shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
980    Reported by Mateusz Golicz.
981
982  + Disable selection of text in cavern log window - you can't currently copy
983    it to the clipboard, so until that's implemented it seems better to disable
984    the ability to select it.  Reported by Wookey.
985
986  + Avoid special "1000" scale entry when exporting.
987
988  + Show 1 page when "One Page" selected.
989
990  + Reload processed data when restricting view.  Fixes failure when
991    restricting view on data just processed via aven.  Spotted by Andrew
992    Atkinson and myself.
993
994  + Don't hide blobs and crosses behind terrain.  Reported by Jenny Black.
995
996  + Fix rendering of crosses using point sprites.  The texture being used was
997    misaligned relative to the image used for the visual fidelity check, so the
998    check always failed and point sprites would never be used.  Where point
999    sprites are supported, they're probably the fastest option - on my netbook
1000    this change improves FPS by ~6 fold when displaying crosses for a large
1001    survey.
1002
1003  + Support drawing blobs using point sprites.  About 5 times faster than using
1004    lines on my netbook.
1005
1006  + Recheck how best to draw crosses and blobs on the first run after Survex
1007    is upgraded (or downgraded) as the rendering code may have changed (we
1008    already recheck when the OpenGL hardware or driver changes).
1009
1010  + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
1011    MPEG4 produces smaller output of higher quality, and should be widely
1012    supported these days.  And I can't get the MPEG1 output to work without
1013    buffer underflows, resulting in a file which doesn't play without
1014    glitches.
1015
1016  + Add OGG video to the list of formats - it's more compact than the others
1017    we currently list, though slower to write.
1018
1019  + Fix export to movie formats for which libav/FFmpeg needs to seek the file
1020    being written.  This was broken by changes in 1.2.27.
1021
1022  + Overhaul movie export for the current FFmpeg API, fixing deprecation
1023    warnings when building against a recent version.
1024
1025  + (Microsoft Windows version): Fix corrupted exported movie files.  1.2.27
1026    changed the movie export code to allow writing to files with non-ASCII
1027    characters in the names, but the new code failed to open the file in binary
1028    mode, leading to corrupt output.  Fixes #81, reported by Erin Lynch.
1029
1030  * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
1031    movie export.
1032
1033  * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
1034    export.
1035
1036* Fix to build without FFmpeg/libav, broken by changes in 1.2.27.  Reported by
1037  James Begley.
1038
1039* The Polish translation is now very close to being complete, thanks to a
1040  substantial update from Mateusz Golicz.
1041
1042* Merge catalan translation updates from Adolfo Jayme.
1043
1044* (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
1045  messages get used automatically.
1046
1047* cavern.tst: Remove random : from after ] - dash ignores the extra character,
1048  but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
1049
1050* cavern.tst: Add expected output for more testcases.
1051
1052* Remove unwanted execute bit from some testcase data.
1053
1054* Use https for more URLs which support it.
1055
1056Changes in 1.2.27 (2016-06-06):
1057
1058* aven:
1059
1060  + Right click on a survey in the survey tree now gives a pop-up menu
1061    with "Hide others", which restricts the view to just that survey
1062    and any subsurveys.  Right click on the root of the survey tree
1063    gives a menu with "Show all" to undo any restriction in effect.
1064    (Currently these are implemented by reloading the file and using
1065    the same machinery as the --survey= command line option, but that will
1066    probably change in the future).
1067
1068  + If there's a sub-survey restriction (from the --survey= command line
1069    option or the new UI described above) it is now shown in brackets after
1070    the survey tree root.
1071
1072  + When reloading a survey, preserve the current view position (previously
1073    the view was recentred).
1074
1075  + When reloading a survey, actually preserve the current scale factor
1076    (this was meant to happen, but the adjustment was applied in the
1077    wrong direction).
1078
1079  + New "File->Extended Elevation..." menu item provides a way to generate
1080    extended elevations for simple cases without having to use the command
1081    line.  Suggested by Fleur Loveridge.
1082
1083  + Don't process key presses if accompanied by an unexpected modifier key.
1084    In particular, this means that aven no longer interferes with Alt+<function
1085    key> (which is typically handled by the desktop) and Alt+<letter> (which is
1086    typically a menu short cut).  Reported by Владимир Георгиев.
1087
1088  + Reduce file loading time by ~5%.  The station name compare function was
1089    something of a hot spot, and optimising it yielded a nice improvement.
1090
1091  + Allow splay legs to be disabled in when printing and exporting.  Mostly
1092    addresses #60.
1093
1094  + SVG export now shows splay legs thinner and in grey.  See #60.
1095
1096  + Fix export of rotated plans and tilted elevations - previously plans were
1097    always aligned with North up, and elevations which weren't exactly side on
1098    were exported as plans.  Reported by Stuart Bennett.
1099
1100  + Fix offset bounding box for exported elevations.
1101
1102  + In print/export dialog the bearing value now wraps if you scroll up past
1103    360 or down past 0.
1104
1105  + Fix greying out of LRUD-based controls in the print/export dialog when the
1106    view is tilted (i.e. not plan or elevation).  This stopped working in
1107    1.2.18 when the pan and tilt spin controls were changed from integer- to
1108    real-valued ones.
1109
1110  + Printouts now show LRUD as pale grey arrows from the station they are
1111    measured from.  Based on patch from Michael Sargent.  Closes #65.
1112
1113  + Take LRUD into account for printout size.  Fixes #72, reported by Erin
1114    Lynch.
1115
1116  + Update movie export code to work with latest version of FFmpeg.
1117
1118  + Make "Show Log" a toggle, so you can click on the button to take a look at
1119    the log, and a second click returns you to the survey view.
1120
1121  + (Microsoft Windows version): Open the font file in binary mode - it looks
1122    like we were lucky and the font file (or at least its current version)
1123    would have loaded OK in text mode despite being binary data.
1124
1125  + (Microsoft Windows version): Exporting to files with non-ASCII filenames
1126    should now work.
1127
1128* cavern:
1129
1130  + Allow tape or backtape to be omitted.  Reported by Erin Lynch.
1131
1132  + Grid convergence is now corrected for when using automatically
1133    calculated declinations (*declination auto <X> <Y> <Z>).  Requested
1134    by Mateusz Golicz on the mailing list.
1135
1136  + Clear any cached calculated declination upon another *declination auto
1137    with different coordinates.  Previously if the date stayed the same,
1138    a previously cached declination for the old coordinates was used.
1139
1140  + Fix check for end of version number array in *required.   We would check up
1141    to 12 version components, the last 9 being bogus.  In practice, *require is
1142    only likely to be used with up to three components, so this wouldn't be an
1143    issue.
1144
1145  + *begin with an invalid prefix could cause a crash in some cases.  Fixed
1146    by patch from Colin Watson.
1147
1148  + Report column locations for errors to do with readings.
1149
1150* Merge translation updates from Jean-Marc.
1151
1152* img library: Better document which members can be set when writing.
1153  Highlighted by email query about use of img API from Владимир Георгиев.
1154
1155* Document how *declination interacts with *calibrate declination if both are
1156  used in the same dataset.
1157
1158* doc/3dformat.htm: Update details of how changes to the current label buffer
1159  are encoded to reflect changes in v8.  Reported by Angus Sawyer.
1160
1161* Use docbook2man instead of docbook-to-man to generated Unix man pages
1162  from SGML source.  The latter seems to be no longer actively maintained, and
1163  docbook2man now does a similarly good job.
1164
1165* Use https for survex.com links, and for other sites which support it.
1166
1167Changes in 1.2.26 (2016-01-07):
1168
1169* aven:
1170
1171  + (Microsoft Windows version): Fix to be able to process .svx files with
1172    cavern again.
1173
1174* (Microsoft Windows version): Simplify upgrading process with innosetup
1175  installer - if Survex is already installed, we now just install to the same
1176  location and use the same start menu folder.
1177
1178* (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
1179  Fixes #79, reported by James Begley.
1180
1181* (Linux version): survex.spec: Fix to work with RPM 4.13.  Fixes #79, reported
1182  by James Begley.
1183
1184Changes in 1.2.25 (2016-01-05):
1185
1186* aven:
1187
1188  + Drop broken code which attempts to fix 2D pitches.  Fixes #73, reported by
1189    Erin Lynch.  #76 tracks the issue the removed code was trying (but failing)
1190    to address.
1191
1192  + When animating, don't try to update station info based on mouse movement
1193    over the survey tree.
1194
1195  + Further improve code to handle cavern subprocess in aven.
1196
1197  + Fix jump to error for filenames containing colons when the error location
1198    doesn't have a column number.  Bug noted by Jenny Black.
1199
1200  + If we encounter bad UTF-8 in cavern output, replace it with a red and white
1201    ? in a diamond (previously we gave up showing output at the first bad
1202    sequence).  This can happen if you process a .svx file which isn't UTF-8
1203    encoded.
1204
1205  + (Unix version): Don't try to set the terminal window title when opening an
1206    editor from the cavern log window - gnome-terminal no longer supports this,
1207    and there doesn't seem to be a portable option for specifying the title for
1208    terminals which do still support this.
1209
1210  + (Microsoft Windows version): Also quote for cmd.exe so that paths with
1211    spaces in work reliably.  Reported by Marco Cotto.
1212
1213* cavern:
1214
1215  + Improve error for mismatched fore/back-sight plumbs, reported by Andy
1216    Edwards (see #78).
1217
1218  + Fix to use correct sd for backcompass.  We were using zero instead, the
1219    most obvious effect of which was that the threshold for warning about
1220    differing COMPASS and BACKCOMPASS was about 71% of what it should have
1221    been, so we were warning in more cases than we should have been.
1222
1223  + Implement support for specifying a length on backsights - if you're using
1224    something like a disto-x, you'll get a distance reading for the backsight
1225    too.  Fixes #71, reported by Erin Lynch.
1226
1227  + Make line counting more robust to mixed line ends.  Noticed in example file
1228    from Pete Smart (see #69).
1229
1230* extend: New --show-breaks option which adds a leg flagged as surface survey
1231  between each points at which a loop has been broken.  Suggested by Jenny
1232  Black.
1233
1234* (Unix version): Update filetype metadata to work with modern desktops.
1235
1236* Fix incorrect reporting of errors reading and writing processed survey data.
1237  Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
1238  IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
1239  external programs using the img library, only Survex).  Reported by Jenny
1240  Black.
1241
1242* Add missing options to extend man page and --help output.  Noted by Jenny
1243  Black.
1244
1245* Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
1246
1247* Fix broken SGML markup in manual.
1248
1249* Fix typo in manual reported by Jenny Black.
1250
1251* Update vim syntax file for newer commands, etc.
1252
1253* Minor translation updates.  Thanks to Piotr Strębski and Jean-Marc.
1254
1255* Fix to compile with FFmpeg 2.9.  Reported by Andreas Cadhalpun in
1256  https://bugs.debian.org/803863
1257
1258* Stop maintaining ChangeLog files.  They make merging patches harder, and stop
1259  'git cherry-pick' from working as it should.  The git repo history should be
1260  sufficient for complying with GPLv2 2(a).
1261
1262* (Microsoft Windows version): The installer requires admin privileges on Vista
1263  and later and OS versions older than Vista are past end of life, so drop code
1264  which tries to set up the registry differently depending if we have admin
1265  privileges or not.
1266
1267Changes in 1.2.24 (2015-09-23):
1268
1269* aven:
1270
1271  + (Microsoft Windows version): Fix the cavern log window.  Reported by Brian
1272    Clipstone.
1273
1274  + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
1275    Reported by Jenny Black.
1276
1277  + If wx was built with thread support, aven now runs cavern from a separate
1278    thread, which works much better under wxMSW (where we can't use select),
1279    and also seems a bit smoother on Linux.
1280
1281  + Fix handling of encoding of filenames when the operating system has no
1282    locale installed corresponding to the language selected for Survex's
1283    messages.
1284
1285  + Undo accidentally committed debugging code which was sending message to
1286    the terminal in 1.2.23.
1287
1288* (Linux version): configure now looks first for wx-config-3.0, which Fedora's
1289  wx3 packages have.  Reported by James Begley.
1290
1291* Indonesian translation fully up to date again.
1292
1293* Manual: Document anonymous stations, based on the text from NEWS.  Reported
1294  by Wookey.
1295
1296Changes in 1.2.23 (2015-09-06):
1297
1298* aven:
1299
1300  + Updating the cavern log window is now much smoother, especially on slower
1301    machines.
1302
1303  + Show "busy" mouse cursor while processing survey data.
1304
1305  + Fix an assertion if you try to start processing a survex file while one is
1306    already being processed.
1307
1308  + Processing a .svx file with an error now still adds it to the file history.
1309    Reported by Martin Green.
1310
1311  + Fix the orientation of the starting end of tubes.
1312
1313* cavern:
1314
1315  + New *ref command to allow specifying an external reference (e.g. where to
1316    find the original survey notes).
1317
1318  + Drop support for showing percentage progress in cavern.  It's confusing in
1319    a multiple-file dataset as it shows progress in the current file so jumps
1320    around.  It also slows down processing, and on a slow machine you'd don't
1321    want that, while on a fast machine processing isn't slow enough for the
1322    progress display to be useful.
1323
1324* French translation is now completely up to date, thanks to Michel Bovey.
1325
1326* Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
1327  OS X so that things like "*cs EPSG:29903" work.  Reported by Graham Mullan.
1328
1329* (Microsoft Windows version): Process survey data with aven rather than
1330  running cavern.
1331
1332* (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
1333  releases have been built with 5.5.3) to see if that solves Ray Duffy's
1334  reported issue with not having file associations for .svx files created.
1335
1336Changes in 1.2.22 (2015-08-17):
1337
1338* aven:
1339
1340  + Ensure that the window has a depth buffer.  Whether it does by default
1341    seems to vary depending on OS and maybe graphics card.  Fixes #55 (terrain
1342    is no longer visible through itself), and also the rendering of passage
1343    tubes.  Thanks to Martin Green for pointing me in the right direction for
1344    finding this fix.
1345
1346* cavern:
1347
1348  + Fix *declination with an angle to actually work.
1349
1350  + Fix assertion if we try to identify a hanging survey by an anonymous
1351    station.
1352
1353  + Improve errors for invalid survey names in *begin, *end, *equate and
1354    *export.
1355
1356Changes in 1.2.21 (2015-07-28):
1357
1358* aven:
1359
1360  + Fix exporting to KML and other text-based formats to always use "." for the
1361    decimal separator - previously "," would be used when the user's locale
1362    specified this for the decimal separator.  Reported by Jan Schorn.
1363
1364  + Implement exporting of survey legs in KML format.
1365
1366  + Put "paddle" placemarker icons on stations in exported KML files, using the
1367    same colour coding for entrances, fixed points and exported points as aven
1368    does.
1369
1370  + Remove the "Coordinate projection" field from the print dialog, as it isn't
1371    relevant there.  Reported by Wookey.
1372
1373  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1374    been too small).  Reported by Wookey.
1375
1376  + Don't rescale if the same file is reloaded, but adjust the volume diameter
1377    as appropriate.
1378
1379  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1380    values on Windows.
1381
1382* cavern:
1383
1384  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1385    radians, but we were passing degrees, which would generally cause the
1386    conversion to the output coordinate system to fail.  Reported by Wookey.
1387
1388  + Fix *fix with standard deviations when *cs is in use, give an error for use
1389    of *fix with standard deviations before *cs.
1390
1391  + Add new *declination command with support for setting the declination
1392    automatically from the IGRF model based on the survey date.  Thanks to the
1393    Therion developers for the IGRF support code, which we're reusing.
1394    Fixes #54, reported by Wookey.
1395
1396  + Allow the units for the zero error to be specified, making it easier to
1397    specify calibration with a scale if you measure the zero error externally
1398    (rather than using the instrument itself).  Fixes #61, reported by Andrew
1399    Atkinson.
1400
1401  + Report the error from PROJ when coordinate conversion fails as part of the
1402    actual error rather than on a separate line.
1403
1404  + Fix use after free after *solve.  This only occurs if a leg between the two
1405    exact same stations appears right before and right after the *solve, which
1406    is unlikely in real data, but the testsuite has an instance of this.  This
1407    was introduced by the repeat leg averaging added in 1.2.17.
1408
1409  + Fix small memory leak when solving network.  This doesn't really matter
1410    when solving at the end of processing as cavern will exit after that, but
1411    if *solve is used we continue processing after solving.
1412
1413* Remove compatibility handling for specifying a country variant of a language
1414  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1415  changed to the standard "en_US" way back in 2001.  This code was mangling
1416  character sets with a "-" in, and is no longer useful.
1417
1418* Ignore any "@<something>" modifier in the language code.
1419
1420* Improve documentation of magnetic declination handling, and cover the new
1421  "*DECLINATION" command.
1422
1423* Document aven's command line options in the manual and its man page.
1424  Reported by Jenny Black.
1425
1426* Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1427  documentation.
1428
1429* Remove references to SpeleoGen from the documentation - it hasn't been
1430  updated for many years, and can't read recent versions of the .3d format.
1431
1432* Strip documentation references to obsolete versions of MS Windows.
1433
1434* doc/HACKING.htm: Update list of debian packages to install to build from git.
1435
1436Changes in 1.2.20 (2015-06-26):
1437
1438* aven:
1439
1440  + When printing, use the top margin rather than the right margin to calculate
1441    the height of the printable area.  In practice, the two values seem to be
1442    the same or very similar by default.
1443
1444  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
1445    Maynard.
1446
1447  + Optimise the size of the about dialog images.
1448
1449  + Add support for reading terrain data which isn't in a .zip file.
1450
1451  + Force a refresh after loading terrain data so that it gets displayed right
1452    away.
1453
1454  + Make checks for terrain data extensions in zip files case insensitive.
1455
1456  + If reading terrain data fails, always report an error and never try to
1457    display it.
1458
1459* cavern: Allow clino readings in diving style data, suggested by Andrew
1460  Atkinson.  Currently these readings are ignored, but a future version will
1461  check that they're consistent with the angle given by the depth gauge and
1462  tape, and perform suitable averaging.
1463
1464* Remove lingering traces of svxedit.
1465
1466* configure: Fix to allow compiling without libav/ffmpeg, as was possible
1467  before 1.2.19.
1468
1469* (Unix version): Install the filetype and aven application icons under
1470  /usr/share/icons/hicolor, which is where they're expected to be these days.
1471
1472* (Unix version): Add %f to Exec in survex-aven.desktop.
1473
1474* (Mac OS X version): Remove useless extra copy of about box images from OS X
1475  disk image.
1476
1477* (Mac OS X version): Only ship one copy of each of the translations.
1478
1479* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1480  libav features we don't use.
1481
1482* (Microsoft Windows version): Reduce the size of the aven binary by disabling
1483  a load of libav features we don't use.
1484
1485* (Microsoft Windows version): Update message files to fix a missing Chinese
1486  message in the installer.
1487
1488Changes in 1.2.19 (2015-06-18):
1489
1490* aven:
1491
1492  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1493    the exported file in 1.2.18.
1494
1495  + Add exporting to Survex .pos format.
1496
1497  + If the measuring line isn't currently active, pressing "Escape" will now
1498    exit full screen mode.
1499
1500  + (Mac OS X version): Change the shortcut for full screen mode to be the
1501    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1502    using since 1.2.7).
1503
1504  + (Mac OS X version): When we centre the view on the station this can
1505    generate a mouse move event, so clear the variable which says we are
1506    dragging before we process a left click on a station.  This avoids random
1507    rotations of the survey when clicking on a station, reported in #47 by Hugh
1508    St. Lawrence.
1509
1510  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1511    icons from being rescaled and looking fuzzy.
1512
1513  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1514    toolbar icons from being rescaled, but which requires an unreleased version
1515    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1516
1517  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1518    the top of the screen, since we can't seem to display the menu bar in this
1519    case like we do on other platforms.
1520
1521  + (Mac OS X version): Enable aven's movie export feature.
1522
1523  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1524    support multi-monitor setups.
1525
1526  + (Mac OS X version): Silence warning visible when aven is run from a
1527    terminal about a missing CFBundleTypeRole.
1528
1529  + When reading terrain data from a .zip file, report an error if the .zip
1530    file is bad, or if it doesn't contain any terrain data we recognise.
1531
1532  + Tweak error message in terrain reading code to distinguish two failure
1533    cases.
1534
1535  + Add viewing angles and scale to footer, and shorten some of the other items
1536    to make room for this extra information.  (Fixes ticket #52, reported by
1537    Erin Lynch)
1538
1539  + If the footer is wider than the printout width, scale down the font used
1540    so that it exactly fits; if the footer is narrower, than space out the
1541    items in in so it uses the full width.
1542
1543  + If the saved size for aven's window exceeds the current display size
1544    (mostly likely because we're now plugged into a smaller monitor), then
1545    reduce the size of the window to fit the display.  If the saved size is <
1546    (480x320), increase it to at least that, as aven isn't usable in a smaller
1547    window.
1548
1549  + Remove crude bodge which tries to pick a nicer initial window size when
1550    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1551    with the same size window it had when it was closed, so the initial size is
1552    only relevant on the first ever run.
1553
1554* Assorted translation updates.  Notably Indonesian is at 100% again.
1555
1556* Stop trying to catch and report signals.  The only real reason to do it is so
1557  we can say "Bug in program detected! Please report this to the authors"
1558  before we exit, but when the program crashes that's pretty obvious.  In aven
1559  we try to pop up a message box for this message, which may fail due to
1560  whatever caused the signal, while with the command line tools there's no
1561  great benefit over just letting the shell report the signal.
1562
1563* Use pkg-config to probe for libav and proj, which sorts out the correct flags
1564  for building on OS X against a static install of libav.
1565
1566Changes in 1.2.18 (2015-06-03):
1567
1568* aven:
1569
1570  + Add support for reading terrain data (from a zip file containing either an
1571    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1572    rendering it as a transparent surface.
1573
1574  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1575    sanely want to perform from the menu.
1576
1577  + Create a "Colour by" submenu of the "View" menu to house the various
1578    colouring options.
1579
1580  + Add "Colour by Gradient" and "Colour by Length".
1581
1582  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1583    which seems more logical, and also allows the dialog to be closed by
1584    pressing "Escape".
1585
1586  + Destroy any existing clipping region before we write the page footer.
1587    Hopefully solves ticket #52, reported by Erin Lynch.
1588
1589  + Don't round bearing and tilt angles to integers when printing and
1590    exporting.
1591
1592  + Add passage export for EPS format.  (Partly addresses ticket #4)
1593
1594  + Add JSON export.  This should be regarded as experimental, and the format
1595    is quite likely to change.
1596
1597  + Pressing F6 now toggles the display of rendering stats, currently FPS
1598    (Frames Per Second) and the number of triangles in the terrain mesh.
1599
1600  + Add a menu item and toolbar button to show the cavern log window if the
1601    currently shown survey data was processed by aven.  Reported by Hugh St
1602    Lawrence in #47, and by Dave Clucas and others previously on the list.
1603
1604  + Add "Save Log" button to Aven's cavern log window.
1605
1606  + In cavern log window, highlight "error" markers in red and "warning"
1607    markers in orange.
1608
1609  + Rework code to read cavern's output.  In particular, we no longer mix
1610    buffered and non-buffered system calls.
1611
1612  + Aven's support for reading colours and font sizes for printouts from
1613    print.ini has never worked - the contents of the ini files are ignored due
1614    to a bug which has been there since the code was added in 2005 - but nobody
1615    has ever complained.  So just strip out that code entirely - we should
1616    support setting the colours and font sizes, but a GUI interface for setting
1617    them would be better.
1618
1619  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
1620    Gee.
1621
1622  + Take the width of the messages used above the compass and clino into
1623    account when calculating how much space to allow for them - now the labels
1624    won't overlap or be cut off in translations where they are long.
1625
1626  + (Mac OS X version): Attempt to address the size of the toolbar icons.
1627
1628* cavern:
1629
1630  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
1631    susscorfa).
1632
1633  + Use the currently set units when outputting measurements in warnings,
1634    errors, and the stats at the end of the run.  Requested by Bill Gee.
1635
1636  + Include column number when a *include file isn't found.
1637
1638  + Show 'error' in front of error messages, like we show 'warning' in front of
1639    warnings.  Fixes #48, reported by Wookey.
1640
1641  + Increase the threshold for warning that fore and back measurements differ
1642    from 2 SDs to 3 SDs.
1643
1644* findentrances: If the 3d file specifies the coordinate system, use it.
1645
1646* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1647  would be nice to have, svxedit doesn't really offer that, and it looks ugly
1648  in a modern desktop.
1649
1650* If we run out of memory while reading a processed survey data file, include
1651  the filename in the error message.
1652
1653* Many translation updates - notably Indonesian and Russian are now the two
1654  most complete translations.
1655
1656* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
1657
1658* Transliterate gradient and infinity symbols if the current character set
1659  lacks them.
1660
1661* Add SVG version of .plt icon.
1662
1663* Manual:
1664
1665  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
1666    highlighting that the previous list was incomplete.
1667
1668  + Document averaging of a group of repeated readings.
1669
1670  + Add a link to the sample data from the manual.
1671
1672  + Remove references to contact addresses which are no longer there.  Remove
1673    offer to post people floppies, and references to a CD image which isn't
1674    available for download.
1675
1676* Remove non-breaking spaces from the diffpos and extend manual pages, as they
1677  actually make the output formatting worse (presumably these used to work
1678  around a since-fixed bug in one of the docbook processing tools).
1679
1680* doc/TODO.htm: Update.
1681
1682* Fix to compile without warnings with 'g++ --std=gnu++11'.
1683
1684Changes in 1.2.17 (2015-02-24):
1685
1686* MacOS X version:
1687
1688  + Update INSTALL file with current status.
1689
1690  + Aven.app now has a custom icon.
1691
1692  + Add icons for all the filetypes supported.
1693
1694  + Add Finder actions for .svx, .3d, .plt and .pos files.
1695
1696  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1697    currently do this for us.
1698
1699  + aven: Fix short-cut for toggling Full Screen mode.
1700
1701  + aven: Make "About" menu item appear.
1702
1703  + aven: Fix "Close" button in about dialog.
1704
1705  + aven: Make custom cursors black with a white outline to match the standard
1706    OS X cursor.
1707
1708  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
1709    still doesn't really work like a standard app though - e.g. you can't load
1710    files from Finder (instead run svxedit.app and use File->Open), the font
1711    size of most menu items is wrong, the icon for the app is the wish icon
1712    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1713    probably more.  I'd probably recommend using another editor (OS X comes
1714    with TextEdit.app for example).
1715
1716  + The documentation is now in a "Docs" directory alongside the apps, rather
1717    than in the rather less obvious "share/doc/survex" directory.
1718
1719  + Default to building for x86_64, since all modern Macs are 64 bit.
1720
1721  + Disable use of liblzma when building wxWidgets for OS X, which was
1722    preventing the build from working on OS X 10.6.8.
1723
1724  + Download wx sources from SF via redirecting link.  Thanks to David A.
1725    Riggs.
1726
1727  + buildmacosx.sh: Handle the mount point for the disk image containing a
1728    space.
1729
1730  + Link with a static build of PROJ for doing coordinate system conversions.
1731
1732  + Build wx with --disable-webview to avoid a compilation failure on OS X
1733    10.10.1.
1734
1735  + Use wx-config --cc and --cxx to get the compilers to use for building
1736    everything else, as wx adds options to them which otherwise cause linking
1737    errors.
1738
1739  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
1740    smaller download.  This means OS X 10.4 is required, but we probably
1741    already need at least 10.5 because that's the minimum version which the
1742    wxWidgets build supports by default.
1743
1744  + Remove unused files and copies of files from the diskimage.
1745
1746* cavern: If the same leg is repeated consecutively, average the readings and
1747  treat as a single leg.
1748
1749* dump3d: Report SEPARATOR used by the file being read.
1750
1751* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
1752
1753* aven:
1754
1755  + Greatly reduce flicker when mouse is moved to the top of the screen in full
1756    screen mode and the menu bar reappears.
1757
1758  + For export formats where scaling is supporting, aven now actually uses the
1759    scale specified in the export dialog (previously it ignored this and used
1760    1:500).
1761
1762  + Reimplement animation so that it's based on angular change per unit of
1763    elapsed time, rather than averaging the time take for the last two scene
1764    redraws.  This gives smoother animation in the face of variable load and
1765    scene redraw time, and should be more consistent between platforms.
1766
1767  + Switching to a point of the compass during auto-rotation now jumps straight
1768    there rather than the two animations fighting.
1769
1770  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
1771    fast.
1772
1773  + Disable stepping the rotation angle when animating (previously we only did
1774    when rotating).
1775
1776  + Speed up start-up a bit - rather than loading icons from individual PNG
1777    files on disk, compile them into the aven binary.
1778
1779* (Unix version): Add "MimeType" field to desktop files so that file
1780  associations work out of the box with modern desktop environments.
1781
1782* Add start of Hungarian translation from Imre Balogh.
1783
1784* Merge in many updates to the Russian translation from "vsuhachev".
1785
1786* Assorted minor updates to other translations.
1787
1788* Create scalable (SVG) versions of file type icons.
1789
1790* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
1791  we're using git.
1792
1793* tests/: Improve test coverage in a few places:
1794
1795  + Extend tests of fore and back sights to test calibration of the back
1796    compass.
1797
1798  + Test "Can't calibrate angular and length quantities together" error.
1799
1800  + Check that "*set names ." works when "." is also the decimal point.
1801
1802Changes in 1.2.16 (2014-10-17):
1803
1804* aven: Add KML export (stations only currently).
1805
1806* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
1807
1808* aven: Fix corrupted names in exported files.
1809
1810* aven: Fix error log window under wxWidgets >= 2.9 to include the system
1811  information before the first log message like it does under wxWidgets 2.8.
1812
1813* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
1814
1815* tests/: Improve test coverage.
1816
1817* Translation updates for many languages, plus the start of translations to
1818  Greek and Polish.
1819
1820* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
1821  by Martin Sluka.
1822
1823* Fix warnings when compiling with clang (which is the default compiler on
1824  Mac OS X).  Reported by Martin Sluka.
1825
1826Changes in 1.2.15 (2014-08-14):
1827
1828* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
1829  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
1830  means that we now support all the coordinates systems which Therion does,
1831  except for a few which don't have X=East and Y=North.  The documentation
1832  for *cs has also been improved.
1833
1834* aven: We no longer persist full screen mode between runs - it's not a
1835  standard behaviour of desktop programs, and it's too easy to go into full
1836  screen mode from the menu and then not be able to get out again because you
1837  don't know the required key shortcut. (ticket#39)
1838
1839* aven: When in full screen mode, moving the mouse to the top of the screen now
1840  makes the menu bar appear.  This provides a non-shortcut way out of full
1841  screen mode, as well as making it easier to perform other operations while in
1842  full screen mode.  The current implementation gives an annoyingly flickery
1843  transition, but hopefully we can improve this in future. (ticket#39)
1844
1845* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
1846  development), we now call EnableFullScreenView() which improves the full
1847  screen mode experience on OS X 10.7 and later.
1848
1849* img library: Improve documentation for img_ERROR_INFO.
1850
1851* tests/: Ship some missing .out files and compare.tst.
1852
1853* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
1854  testcase, and extend it to cover a variant of the situation reported as a bug
1855  in therion by Bill Gee to the therion list.
1856
1857* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
1858  for the survex package and on tk for the svxedit package.
1859
1860Changes in 1.2.14 (2014-07-05):
1861
1862* img library: Add ability to store a PROJ4 string describing the coordinate
1863  system in use in 3d v8 files.
1864
1865* aven: If the 3d file specifies a coordinate system, then use it for exporting
1866  to formats which need to know (currently GPX).  If the input file doesn't
1867  specify the coordinate system, allow the user to enter a PROJ4 string in the
1868  export dialog.
1869
1870* aven: You can now quickly zoom to a particular area by holding down the
1871  "Shift" key and dragging with the left mouse button to create a rectangular
1872  "rubber band box" around the area you wish to zoom to.  If you release the
1873  "Shift" key while still dragging, the box is centred on the start point
1874  rather than having one corner there.
1875
1876* aven: Fix exporting of passage tubes in elevations and extended elevations
1877  - previously up and down were getting drawn across the page!
1878
1879* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1880  1.2.13.  (Reported by Brian Clipstone)
1881
1882* aven: Fix the conditions on which the menu item "Cancel measuring line" is
1883  enabled - previously it was hard to actually cancel it via the menu.
1884  Reported by Hugh St Lawrence.
1885
1886* aven: Fix wx assertion failures when showing hit test debug view on platforms
1887  such as 64-bit Linux.
1888
1889* aven: When viewing from above, show "Plan" above the "clino" which indicates
1890  the tilt angle (instead of "Elevation -90°").
1891
1892* aven: The extended font data now loads faster, and also uses less memory on
1893  64-bit platforms.
1894
1895* aven: Dragging the vertical divider between the side panel and the 3D view
1896  now only updates when you finish the drag, as redrawing continuously just
1897  looks clunky except on an ultra-fast machine.
1898
1899* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
1900  the space available in the aven UI.
1901
1902* cavern: Add a *cs command to allow setting the coordinate system for *fix
1903  commands, and the coordinate system used for processed survey data.  The
1904  latter is now stored in 3d v8 format files.
1905
1906* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
1907  and handle it in the same way as the "DUPLICATE" flag in .svx files.
1908
1909* cavern: If there's more than one *fix command with coordinates, still
1910  actually fix the second and subsequent ones, to avoid triggering bogus errors
1911  about unconnected surveys.
1912
1913* cavern: If there's more than one *fix command with coordinates, report the
1914  station name of the previous one, plus the file and line number where it was.
1915
1916* cavern: Fix handling of the rather contrived case of *fix with no coordinates
1917  followed by *solve and then another *fix with no coordinates not to access
1918  freed memory.
1919
1920* dump3d: Report any specified coordinate system.
1921
1922* doc/3dformat.htm: Update to document how the coordinate system is stored.
1923
1924* (Microsoft Windows version): Include dump3d in the installer.
1925
1926* Fix a compiler warning.
1927
1928* Improve test coverage.
1929
1930Changes in 1.2.13 (2014-05-15):
1931
1932* aven: Fix --print option to wait for printing to happen before exiting
1933  (previously it would exit right after opening the print dialog, so you
1934  couldn't actually print anything out using it).
1935
1936* aven: Increase the threshold for how close the pointer needs to be to a
1937  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
1938  Hugh St Lawrence.
1939
1940* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
1941  if increasing the minimum pointer to station threshold helps Hugh's problems
1942  with using aven on a touch screen device.
1943
1944* aven: The measuring line was unable to see stations which had just been
1945  revealed by toggling surface or underground legs on - this is now fixed.
1946
1947* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
1948  many entries are in each box (toggled by F3).
1949
1950* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
1951  off and back on.
1952
1953* aven: Create the empty hit-test grid data structure lazily, to reduce start
1954  up time a little.
1955
1956* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
1957  and *end commands to instead talk about "survey names".
1958
1959* cavern: For ages cavern has warned if you reentered a survey, but this
1960  warning was suppressed if it occurred at the same line of the same file as
1961  the survey was first entered, but this can only happen if you include the
1962  same survey file more than once, which isn't a sensible thing to do for a
1963  file with actual survey data in (you might reasonably do it to set up survey
1964  grade details or something like that).  The warning is now given in this
1965  situation too.
1966
1967* cavern: After 5 warnings about reentering a survey we give up warning about
1968  it, but we used to keep reporting where the survey was originally entered -
1969  this secondary diagnostic message is now silenced when the main message is.
1970
1971* (Microsoft Windows version): Compile C code with optimisation on.
1972
1973* Add the start of a Russian translation, with messages take from therion.
1974
1975* Minor translation updates to French.
1976
1977* Fix compiler warning from GCC.
1978
1979* Testsuite improvements:
1980
1981  + Test that "..." anon station works.
1982
1983  + cavern.tst: Check number of errors returned by all testcases which should
1984    fail and give an error count.
1985
1986  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
1987
1988Changes in 1.2.12 (2014-04-14):
1989
1990* aven: Fix measuring line to show change in altitude rather than altitude
1991  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
1992  Clipstone.
1993
1994* aven: Fix printing when built with wxWidgets 3.0.
1995
1996* aven: Several visual improvements to printouts:
1997
1998  + Move the numbers below the scale bar down a little so that they don't
1999    overlap the scale bar ticks.
2000
2001  + Set the clipping region after we draw the page border and info box to avoid
2002    clipping the border in print preview.
2003
2004  + Tidy up the appearance of the compass and elevation arrow.
2005
2006* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
2007  <http://bugs.debian.org/739332>.
2008
2009* aven: Fix to build with older libav where avcodec_free_frame() isn't
2010  available.
2011
2012* (Linux version) survex.spec: Update spec file used for building RPM packages.
2013
2014* (Unix version): Add "Keywords:" entry to .desktop files.
2015
2016* (Unix version): Enable large file support, mostly to support filing systems
2017  which return 64 bit inode values, such as CIFS mounts.
2018
2019* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
2020  rather than any character which is a letter in the current locale.
2021
2022* Various translation updates.
2023
2024Changes in 1.2.11 (2014-01-28):
2025
2026* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
2027  Reported by Kevin Dixon.
2028
2029* aven: Embed the font data for the first 256 Unicode characters for use in the
2030  survey pane into the compiled aven binary to reduce start up overhead.  Any
2031  additional characters needed are loaded from a data file only if/when a
2032  character >= U+100 is actually needed (as before).
2033
2034* aven: Fix display of Unicode characters above 256 when there's a character
2035  <= 256 earlier in the same string.
2036
2037* aven: Use the actual width of Unicode characters above 256 rather than
2038  assuming they are 16 pixels wide.
2039
2040* aven: If full screen, don't show the side panel when a new file is opened
2041  (e.g. via Ctrl+O).
2042
2043* aven: Don't give an assertion failure when showing passages for a cave with
2044  no vertical extent.  Reported by Jonny Prouty.
2045
2046* aven: Change terminology in print dialog - say "legend" instead of "info
2047  box".
2048
2049* aven: Add option to show the tilt angle as a percentage gradient.
2050
2051* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
2052  indicators.
2053
2054* aven: All length units are now translatable.
2055
2056* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
2057  will reduce code size and also the number of deprecation warnings about
2058  gluErrorString on Mac OS X 10.9.
2059
2060* (Microsoft Windows version): aven: Try to work around redraw issues related
2061  to the measuring line by redrawing the whole window, which doesn't seem to be
2062  measurably slower.
2063
2064* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
2065  give an error rather than quietly ignoring the attempt.
2066
2067* cad3d: Make cad3d remap control characters and spaces in station names when
2068  generating PLT output in the same way aven does.
2069
2070* Various translation updates (particular thanks to Eric Madelaine and Dennis
2071  Baudys), including the start of a Bulgarian translation, with messages taken
2072  from Therion and elsewhere.
2073
2074* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
2075  GetUserDefaultUILanguage() to get the UI language to use.  For older
2076  versions, continue to use GetUserDefaultLCID().
2077
2078* (Microsoft Windows version): The Indonesian translation will now be used
2079  automatically when the system language is set to Indonesian.
2080
2081* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
2082  A. Riggs for his work on this.
2083
2084* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
2085  checksum check for the downloaded wx sources.
2086
2087* Fix a lot of the compiler warnings when building with clang.
2088
2089* doc/manual.sgml: Add missing quantities to the list documented as accepted by
2090  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
2091  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
2092  mentioned in list of the units that can be set for them); COUNT (missing
2093  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
2094  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
2095
2096* Test suite: Improve test coverage for cavern.
2097
2098Changes in 1.2.10 (2014-01-15):
2099
2100* aven: Fix assertion if two mouse buttons are held down at the same time.
2101  If dragging with more than one mouse button held down, releasing one causes
2102  another which is still held down to take effect.  Reported by Brian
2103  Clipstone.
2104
2105* aven: If we fail to start the external editor when the user clicks on an
2106  error or warning from cavern, show an error box.
2107
2108* aven: If the survey has a title, add it as a top-level <title> element to
2109  exported SVG files.
2110
2111* aven: Escape '<', '>', and '&' in labels in exported SVG files.
2112
2113* aven: In GPX export, set the <time> element to the datestamp from the 3d
2114  file.
2115
2116* aven: Don't try to write the title if it isn't set or is empty when exporting
2117  GPX files.
2118
2119* aven: Don't bother looking up the printer page setup info when exporting.
2120
2121* (Microsoft Windows version): aven: Fix crash on "File->Print" or
2122  "File->Export" under Windows XP, reported by Brian Clipstone.
2123
2124* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
2125  encoded filename which could occur if run without being asked to load a file
2126  on startup.
2127
2128* (Microsoft Windows version): aven: Compile with optimisation on.
2129
2130* img library, aven: Although processed CMAP data files are often referred to
2131  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
2132  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
2133  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
2134  continue to do so in case anyone is relying on it, but also check for the
2135  other extensions.
2136
2137* img library: Add new "datestamp_numeric" field to struct img giving the
2138  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
2139  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
2140  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
2141  timezone wrong.
2142
2143* img library: Fix my_strcasecmp() to handle top-bit set characters better.
2144
2145* cavern: Fix NULL pointer dereference when processing Compass DAT file without
2146  'SURVEY DATE:'.
2147
2148* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
2149
2150* doc/manual.sgml: Note the station length limit Smaps used.
2151
2152* Fix some compiler warnings if built with glibc's fortify source feature
2153  enabled.
2154
2155Changes in 1.2.9 (2014-01-08):
2156
2157* Document --3d-version in cavern man page and the manual.
2158
2159* aven: Fix compilation error in movie export code with recent libavi.
2160
2161* aven: Fix warning on stderr when export a movie as MPEG.
2162
2163* img library: In non-hosted mode, don't define GETC and PUTC if they're
2164  already defined, to allow easy overriding with getc_unlocked() and
2165  putc_unlocked() (which are significantly faster on Linux).
2166
2167* img library: In non-hosted mode, check that int is at least 32 bits,
2168  and if not, use long.  In practice, platforms with 16 bit int are mostly
2169  obsolete, but it's not hard to be portable here.
2170
2171* img library: Add test that img.c and img.h compile in non-hosted mode
2172  (regression test for issue fixed in 1.2.8).
2173
2174* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
2175
2176* Update translations from launchpad and from existing similar messages.
2177
2178* Fix some compiler warnings.
2179
2180Changes in 1.2.8 (2013-10-29):
2181
2182* cavern: Fix handling of anonymous wall stations ('..' by default) to
2183  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
2184  Holder.
2185
2186* cavern: Tweak .err file output not to lose the space in front of certain
2187  statistics when the value gets large.
2188
2189* cavern: Eliminate redundant progress message when solving simultaneous
2190  equations.
2191
2192* aven: Add a format drop down to the export dialog, and only show fields which
2193  are meaningful and supported for the currently selected export format.  The
2194  format defaults to that used most recently.  The "Elements" and "View" boxes
2195  have been swapped in the print and export dialogs as that layout works much
2196  better when the "View" box is hidden.
2197
2198* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
2199  - now works again.  Reported by Anthony Day.
2200
2201* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
2202  this release the projection which the survey coordinates are in defaults
2203  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
2204  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
2205  projection string.  The ability to specify this projection in a better
2206  way is coming soon.
2207
2208* aven: New export options "Origin in centre" and "Full coordinates" - the
2209  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
2210
2211* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
2212  time ago, so update references.
2213
2214* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
2215  with wxMSW 2.9.5.  Reported by Brian Clipstone.
2216
2217* aven: Make right click in an empty presentation mark the current position and
2218  open it to edit, instead of crashing.
2219
2220* aven: Update movie export code to work with latest libav API.  Reported by
2221  Sebastian Ramacher.
2222
2223* aven: Improve reporting of errors during the process of exporting a movie.
2224
2225* aven: Don't try to close the movie if we aren't producing one.
2226
2227* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
2228
2229* aven: Fix to build with wxMSW 2.9.5.
2230
2231* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
2232
2233* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
2234  ago, so add a new --skencil option to specify this output format.  The old
2235  name (--sketch) is still recognised for compatibility.
2236
2237* cad3d: Make --marker-size work for Skencil and SVG output.
2238
2239* dump3d: Make --show-dates option show dates for XSECT.
2240
2241* img library:
2242
2243  + Fix to work once more when used outside of Survex (missing definition of
2244    max() macro and a bad call to free() in img_close() for a file opened for
2245    reading).
2246
2247  + Use lround() instead of round(), and make the tests around whether we use
2248    the library function or the our fallback implementation saner.
2249
2250  + Fix // comments in C code for portability to pre-C99 compilers which don't
2251    support these as an extension.
2252
2253  + Can now be compiled as C++ as well as as C.
2254
2255* (Microsoft Windows version): The installer is now built with a newer version
2256  of Innosetup, and includes translations for all the languages which Survex
2257  itself has any translations for.
2258
2259* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
2260
2261* Minor translation updates.
2262
2263* tests/Makefile.am: Distribute files for "normal_bad" testcase.
2264
2265Changes in 1.2.7 (2013-07-27):
2266
2267* Add support for anonymous stations, which are indicated by one, two or three
2268  separator characters - with the default separator of '.', that means '.',
2269  '..', and '...' are anonymous stations.  Single separator ('.' by default)
2270  is an anonymous non-wall point, double separator ('..' by default)
2271  is an anonymous wall point at the end of an implicit splay), and triple
2272  separator ('...' by default) is an anonymous point (with nothing special about
2273  the leg).  A new *alias command allows '-' to be mapped to '..' for
2274  compatibility with pocket topo: *alias station - ..
2275
2276* New version 8 of the 3d format:
2277
2278  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
2279
2280  + New explicit file-wide flag for 'this is an extended elevation', rather
2281    than modifying the survey title to indicate this.
2282
2283  + The survey prefix is often unchanged from one leg to the next, so use a
2284    spare flag to compactly indicate when there's no label change.
2285
2286  + The data style of each leg is now stored.
2287
2288  + The "processed at" time is stored as seconds since 1970 rather than a
2289    human-readable string.
2290
2291  + Since 3d v8 features significant changes to the format, the format
2292    documentation for v7 and earlier has been split off into 3dformat-old.htm.
2293
2294* img library:
2295
2296  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
2297
2298  + Handle .pos files containing unnamed stations - don't suck the next line in
2299    as the station name, and set img_SFLAG_ANON for them.
2300
2301  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
2302    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
2303    elevation, in place of appending " (extended)" to the title.  Internally we
2304    still append this to the title (and remove it upon reading) when writing
2305    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
2306    explicitly in the file.
2307
2308  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
2309
2310* aven:
2311
2312  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
2313    now, and the wx developers consider even 2.8 to be rather long in the
2314    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
2315    formally dropping support for older versions allows a number of workarounds
2316    to be removed from the aven source code.  Also, features deprecated in
2317    wxWidgets 2.9 are no longer used in our code.
2318
2319  + Don't run incremental search on every key-press, as on a slow machine the
2320    short initial search(es) will take a while but not be useful.  Instead only
2321    actually run the search when we're told there are no more key-presses
2322    queued up.
2323
2324  + Implement support for including cross-section information in exported SVG
2325    and DXF files (ticket#4).  The DXF export is untested currently.
2326
2327  + Show splay legs faded by default, with menu options to hide them or show
2328    them like other legs.
2329
2330  + Speed up loading a .3d file with cross-sections by using a map to convert
2331    station names to positions.
2332
2333  + In the cavern log window, don't highlight a file:linenumber if there's no
2334    message after it, which avoids highlighting the "Included from" lines
2335    wrongly.
2336
2337  + Fix not to crash when trying to report an error while starting up.
2338
2339  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
2340    the OS X standard shortcut Shift-Command-F (previously we used F11, but
2341    that's used by the desktop).
2342
2343  + Add checks for errors when reading the font file.
2344
2345  + Remove useless extra quoting when invoking vim to show the location of an
2346    error from cavern.
2347
2348  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
2349
2350  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2351    in the dialog in sync.
2352
2353* cavern:
2354
2355  + Demote errors about invalid dates to warnings, since we've accepted *date
2356    for ages without any checks on the value, and so existing datasets
2357    probably contain invalid dates and dates in other formats.  (ticket#19)
2358
2359  + New *alias command allows '-' to be mapped to '..' for compatibility with
2360    pocket topo: *alias station - ..
2361
2362  + We want to warn if there's a clino reading which it would be impossible to
2363    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2364    read "93" (it's probably a typo e.g. for "39").  However, the gradient
2365    reading from a topofil is typically in the range 0 to 180, with 90 being
2366    horizontal.  Really we should allow the valid range to be explicitly
2367    specified, but for now we infer it from the zero error - if this is within
2368    45 degrees of 90 then we assume the instrument can read between 0 and 180
2369    degrees.
2370
2371  + If the survey isn't all connected, still run survey tree checks and report
2372    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
2373    Dixon for the report which highlighted this issue.
2374
2375  + Report a warning if *begin SURVEY has a separator character in SURVEY.
2376
2377  + Report column numbers as well as line numbers for some cavern errors and
2378    warnings.
2379
2380  + Adjust width of node stats table to fit longest count when there are more
2381    than 9999 of a particular order of node.
2382
2383  + If the argument to *include has an opening double quote but the closing
2384    double quote is missing, then skip trying to open the file.
2385
2386  + Move "Station X referred to just once" warning after non-existent survey
2387    check - if both fire, the non-existent survey error is likely to be more
2388    relevant.
2389
2390  + We no longer follow an error for a bad reading in passage data with a bogus
2391    "End of line not blank" error, but instead check the remaining readings on
2392    the same line.
2393
2394  + We no longer follow an error about OMIT for a required reading with a bogus
2395    "End of line not blank" error.
2396
2397  + Report an error if the scale factor in *calibrate is zero - it doesn't make
2398    sense and probably means someone reversed the arguments to *calibrate.
2399
2400  + Report the parent include files starting from the outermost, as that's more
2401    logical when there are multiple levels involved.
2402
2403  + If we were expecting a numeric field and instead get something which starts
2404    with '+', '-', or '.' but which isn't a number, then fix the error to
2405    include that character in the token reported.
2406
2407  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2408    first item.
2409
2410* cad3d: Check for errors from img_rewind() and report them.
2411
2412* dump3d:
2413
2414  + Build, install and package dump3d as standard - it's useful for grabbing
2415    info from 3d files in scripts.
2416
2417  + Add --show-dates option.
2418
2419  + Show only 2 decimal places on coordinates and passage dimensions.
2420
2421  + Report the data style of legs.
2422
2423  + Report if the file is an extended elevation.
2424
2425  + Report img_STOP as STOP rather than CODE_0xffffffff.
2426
2427* Test suite:
2428
2429  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2430    expected output so it passes reliably.
2431
2432  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2433    'Deleted' stations upon failure are the more natural way round.
2434
2435  + Add more testcases, expand some existing testcases, and add expected output
2436    for more.
2437
2438* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2439  appropriate C and C++ compilers to use, and link mingw build statically to
2440  avoid needing the libgcc DLL (which newer GCC seems to have by default).
2441
2442* (Unix version): When determining the character set for command-line tools,
2443  check environmental variable LANG after LC_ALL and LC_CTYPE.
2444
2445* When determining the language, check environmental variable LC_ALL before
2446  LC_MESSAGES and LANG (but after SURVEXLANG).
2447
2448* If we don't find the message file, only give an error if it was specified
2449  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
2450  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2451  settings.
2452
2453* There are a handful of hard-coded English message strings for reporting
2454  errors trying loading message files, etc.  These are all now ASCII, as if we
2455  fail trying to open a message file, it's more likely the encoding isn't
2456  set correctly.
2457
2458* Prune strings we are no longer using and are probably unlikely to use again
2459  into a new file po_codes_dead, so that translators don't get presented with
2460  them to translate.
2461
2462* Merge lots of translation updates.  Most translations are now complete or
2463  close to complete.
2464
2465* Add start of Indonesian translation from Arief Setiadi Wibowo.
2466
2467* Fix various compiler warnings when building from source.
2468
2469* Include scripts gdtconvert and gen_img2aven in the source distribution.
2470
2471Changes in 1.2.6 (2012-02-23):
2472
2473* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2474
2475* (Microsoft Windows version): Include JPEG images for aven in the installer
2476  package (ticket#35).
2477
2478* cavern: If we have a reference to a station in a non-existent survey, give a
2479  helpful error rather than saying the station hasn't been exported from the
2480  survey.  (Bug reported by Martin Green via email)
2481
2482* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
2483  Kahler.
2484
2485* findentrances: Add findentrances utility from Olaf Kahler which produces a
2486  .gpx file with waypoints for entrances.  This needs libproj so is disabled
2487  by default for this release - to enable it install the development stuff for
2488  libproj and build survex with:
2489
2490      make FINDENTRANCES=findentrances
2491      make install FINDENTRANCES=findentrances
2492
2493* dump3d: Add support for showing img_ERROR_INFO items.
2494
2495* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2496
2497* Incorporate a French translation from launchpad I'd previously copied the
2498  English version of by mistake.  Attempt to correct mistranslation of "survey
2499  file".
2500
2501Changes in 1.2.5 (2012-01-03):
2502
2503* aven:
2504
2505  + The survey tree in the left panel is now in sorted order once more.
2506
2507  + No longer fails with an assertion if used for a long time (we were leaking
2508    an OpenGL list each time one had to be regenerated).
2509
2510  + Now builds with newer FFmpeg library.
2511
2512  + Draw measuring line in front of the indicators rather than behind them.
2513
2514  + Loading a new file (or reloading the current one) no longer invalidates
2515    the OpenGL lists for the compass and clino, so will be a fraction faster.
2516
2517* Improve handling of attempts to look up translated messages before the
2518  message subsystem is fully initialised (which only happens if there's an
2519  error early on).
2520
2521* Improve the survex(7) man page text, and fix it to be marked as section 7 in
2522  the man page source as well as in the filename.
2523
2524Changes in 1.2.4 (2012-01-01):
2525
2526* aven:
2527
2528  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2529    initialised, which doesn't cause problems in some machines, but causes aven
2530    to abort on others.  This is now fixed, and there's a check in place to
2531    help avoid similar issues in future. (ticket#34)
2532
2533  + Always use metres or feet for the depth colour key, and chose a consistent
2534    precision by looking at the depth range. (ticket#30)
2535
2536  + Show the depth units below the colour bar rather than after every value.
2537
2538  + When zooming way in, stay in metres rather than switching to cm.
2539
2540  + On the scale bar, say “1 mile” rather than “1 miles”.
2541
2542* Translation updates for Catalan, French and Slovak.
2543
2544Changes in 1.2.3 (2011-12-31):
2545
2546* Fix to build with wxWidgets 2.9.2.
2547
2548* (Mac OS X version):
2549
2550  + Processing .svx files from aven now works.
2551
2552  + Remove spurious blank lines from the licence text in "Get Info".
2553
2554  + Don't create the help menu at all, as it is empty (because the "About"
2555    entry goes elsewhere) and sometimes seems to appear in the UI.
2556
2557  + INSTALL.OSX: Update to reflect current status.
2558
2559* aven:
2560
2561  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
2562
2563  + Improvements to text plotted on the survey pane:
2564
2565    - Support plotting Unicode character points > 256 by lazily loading the
2566      data for them from the font file and plotting them with a direct call to
2567      glBitmap(), which is slower but doesn't require a display list per
2568      character.
2569
2570    - Adjust the spacing from fixed width to putting a one pixel gap either
2571      side of each one character (so two between adjacent glyphs).  Mostly this
2572      reduces the horizontal width, but it adds a pixel for characters like "m"
2573      and two in a few cases.
2574
2575    - Fix .pixelfont file generation to correctly handle characters wider than
2576      8 pixels.
2577
2578  + Fix expected cross shape so don't always reject using texture mapping to
2579    draw crosses.
2580
2581  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2582    as those consisting of just one.  Previously we would trip over the empty
2583    tube later.  Such tubes can for example be created by extend if a splay shot
2584    is the start or end of a tube.
2585
2586  + Make the green colour used for entrances in the survey tree the same
2587    (slightly darker than before) green used for the entrance blobs.
2588
2589  + Report the version of the library we're actually running with if built
2590    against wx >= 2.9.2.  Make it clear that the version reported is the
2591    version *built* with for wx < 2.9.2.
2592
2593* extend:
2594
2595  + Copy the end markers for passage tubes.
2596
2597  + Preserve left and right data for tubes (previously they were set to -1.0
2598    which means "no info").
2599
2600* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2601  was no longer used - it certainly is!
2602
2603* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2604  messages, and curly single right quote instead of straight ASCII apostrophe.
2605  Fall back to using straight ASCII versions if we can't represent them in the
2606  current character set.
2607
2608* Translation updates for Catalan, French, Slovak and Spanish.
2609
2610* Test suite:
2611
2612  + Add test coverage for interleaved diving data.
2613
2614  + Add testcase for diving data with topofil-style distance.
2615
2616Changes in 1.2.2 (2011-10-06):
2617
2618* aven:
2619
2620  + Replace the textured-mapped font drawing with an approach based on
2621    glBitmap.  This doesn't suffer from the character alignment issues which
2622    the textured-mapped fonts had, and is actually significantly faster on some
2623    machines.  The current font used is (mostly) fixed-width, but this isn't an
2624    inherent limitation - it was just the easiest font data to convert to a
2625    usable format.
2626
2627  + Fix assertion failure due to rounding differences on loading certain .3d
2628    files.  (ticket#26)
2629
2630  + Fix assertion failure when turning on 3D passages if they stick out higher
2631    or lower than any station.  (ticket#29)
2632
2633  + Fix grid not to disappear when blobs are turned on and blobs are drawn
2634    using lines.
2635
2636  + If a degree sign isn't available in the character set in use, transliterate
2637    it to 'dg' rather than skipping it.
2638
2639  + Fix message which should have been a degree sign but got lost in the format
2640    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
2641    that bearings in the status bar now have a degree sign after them if they
2642    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2643
2644  + Fix print dialog to calculate the scale required for "One page" right
2645    before it calculates how many pages are required, so we don't end up
2646    something other than 1x1 being shown when the user changes settings.
2647
2648  + Update the calculations for picking a scale and for deciding how many
2649    pages are needed to take into account the change in info box height made
2650    in 1.2.1.
2651
2652Changes in 1.2.1 (2011-10-04):
2653
2654* Translation updates for US English.
2655
2656* aven:
2657
2658  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2659    it now shows colours for dates and errors as well as depths.
2660
2661  + In the colour key for "colour by date", change "No info" to "Undated".
2662
2663  + Remove the dark grey background from the colour key and just put a single
2664    pixel black border around the colours.  This is more in keeping with the
2665    other controls, and means the colours are now on a black background so more
2666    visually similar to the survey legs.
2667
2668  + Move the colour key's "Undated"/"Not in loop" entry down a little to
2669    improve the appearance.  Make each section a pixel taller.
2670
2671  + Allow "Colour by X" to be selected even if there's no data for X or only a
2672    single value of X used (the colour key is much smaller in these cases, and
2673    does still provide some useful information).
2674
2675  + Fix incorrect calculation of depth colouring for survey legs which straddle
2676    a depth band boundary.
2677
2678  + The scale bar, compass, clino, and colour key now all have right click
2679    menus which allow related actions to be performed (especially handy in
2680    full-screen mode).
2681
2682  + Improve the font used on the survey pane - it now contains the '-'
2683    character (so the clino now shows negative angles as negative, and dates
2684    in the colour key are now hyphenated).  Also the spacing and alignment
2685    are a little better, though still not perfect.
2686
2687  + PLT file export now handles spaces and control characters in station names
2688    by escaping them with '%' as in URLs.
2689
2690  + Pressing "Enter" on a station in the tree control now centres the view on
2691    that station.
2692
2693  + The scale bar is now cached in an OpenGL display list since it often gets
2694    redrawn exactly the same - for example, when rotating, panning, etc.
2695
2696  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2697    then forces a refresh of the survey pane.  This is intended as a debugging
2698    aid - if pressing F5 changes the display at all then there's a missing case
2699    where a list should have been invalidated (please report if you find such
2700    a case as it is a bug).
2701
2702  + We now automatically track which OpenGL display lists need to be
2703    invalidated on window width or height changes.
2704
2705  + Increase scale bar maximum width from 65% of the window width to 75% as it
2706    was in 1.0.x (except that if that would overlap the clino we now reduce
2707    that proportion down until it reaches 50%).  Make the limit of zooming in
2708    the same as in 1.0.x.  (ticket#23)
2709
2710  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2711    the application was fullscreen (the dialog got opened under the main
2712    window!)  To work around this, aven would switch out of full screen mode
2713    temporarily while showing a dialog.  This case works properly with recent
2714    wxGTK, so disable our workaround with versions we know work.  Also, apply
2715    the workaround only for wxGTK, not everywhere except on Microsoft Windows
2716    as there's no reason to think we need it for other platforms.
2717
2718  + Grey out the "View North" action when we're already viewing North, and
2719    similarly for other compass points.
2720
2721  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
2722    info in the "About" dialog.
2723
2724  + Fix to set the correct filename on the root of the survey tree - previously
2725    the filename of the previous file loaded was used!
2726
2727  + The movie export code now works with newer versions of the FFmpeg libraries
2728    as well as still working with older versions.
2729
2730  + Fix mixed up messages - the print dialog now says "View" on the left
2731    subgroup of controls rather than some unrelated message.
2732
2733  + On printouts, combine the "Plan View"/"Elevation" info box field with the
2734    field which gives the bearing and reduce the height on the info box by the
2735    removed field, so it's now 3cm for plans and elevations, as for extended
2736    elevations.  Report the tilt angle for tilted elevations which it seems has
2737    been missing for ages (it's not in recent 1.0.x either).
2738
2739  + Tweak the exact positioning of informational text on printouts to look
2740    nicer and make better use of the available space.
2741
2742  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
2743    dialog.
2744
2745  + Make the sign of the tilt angle for printouts consistent with the sign
2746    shown by the "clino" in the survey pane.
2747
2748  + In the "Print" dialog, when in plan view disable the "Plan view" button,
2749    and similarly for the "Elevation" button.
2750
2751  + (Microsoft Windows version): Sort out appearance of custom cursors.
2752
2753  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
2754
2755  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
2756    you can't get out again easily, so add code to explicitly check for F11
2757    being pressed and toggle full screen.
2758
2759* (Linux version): Fix the RPM .spec file for where man pages now get installed
2760  and package aven.svg and the vim support files.  (Fixes from James Begley)
2761
2762* "make check" now performs several checks on the translation files.
2763
2764* More messages are now available to be translated.
2765
2766* cavern: Fix reporting of ranges of survey coordinates, which was broken by
2767  the message handling changes in 1.2.0.
2768
2769* Fix warning when compiling with GCC.
2770
2771* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
2772  sudo for installing on Unix.
2773
2774* In the manual, replace the instructions for building from source with a
2775  pointer to the clearer instructions in INSTALL.
2776
2777* In the manual, make it clear that installing with administrator rights
2778  also applies to newer platforms than XP.
2779
2780* doc/TODO.htm: Update.
2781
2782Changes in 1.2.0 (2011-09-20):
2783
2784* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
2785  English.
2786
2787* tests/smoke.tst: aven no longer requires an X display for --help or
2788  --version, so replace skip of this check with a check that this remains the
2789  case.
2790
2791* We now use the standard .po and .pot file formats for storing translations
2792  (rather than the Survex-specific messages.txt format), and then translate
2793  these into Survex's .msg format.
2794
2795* (Unix version): Move survex man page to section 7 (since it isn't documenting
2796  an actual command).
2797
2798* (Unix version): Write each generated man page to a temporary file, then
2799  atomically rename, to avoid leaving an empty or partial man page behind if
2800  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
2801  recurrence of that).
2802
2803* (Unix version): Default to installing docs into /usr/share/doc/survex rather
2804  than /usr/doc/survex.
2805
2806* aven:
2807
2808  + Fix handling of accented characters in the survey pane.
2809
2810  + Aven icon redrawn in SVG format - it's now a vector image which looks
2811    nicer at larger sizes.
2812
2813  + Explicitly request double-buffering, which seems to be needed for systems
2814    with GLX >= 1.3.
2815
2816  + Fix crash while trying to load certain .3d files.
2817
2818  + Movie export code updated to work with more recent versions of FFmpeg.
2819    Currently this is disabled in Microsoft Windows builds, pending getting the
2820    required libraries set up for building releases.
2821
2822  + Reporting of errors during movie export improved.
2823
2824  + Force playback speed to "x1" during movie export.
2825
2826  + Use stock IDs for buttons where appropriate - such buttons may now be
2827    rendered with icons on some platforms.
2828
2829  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
2830    ISO8859-1).
2831
2832  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
2833    as it's no longer required with modern versions.
2834
2835  + Don't redraw the survey on every mouse movement in the survey pane unless
2836    the measuring line is (or just was) active.  (ticket #17)
2837
2838* cavern:
2839
2840  + Drop "non-fatal" from the report of how many errors there were at the end
2841    of the run - it just confuses users - we won't even get here if there's a
2842    fatal error!
2843
2844  + Add --3d-version option to allow the user to specify the version of the 3d
2845    format to output.  (ticket#21)
2846
2847* img library:
2848
2849  + Make the highest and lowest valid values for img_output_version available
2850    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
2851
2852* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
2853  volume actually gets mounted.  Fix URL for downloading wxWidgets.
2854
2855Changes in 1.1.16 (2011-05-16):
2856
2857* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
2858  Portuguese, and US English.
2859
2860* Use horizontal ellipses character rather than '...' and right arrow character
2861  rather than '->' where these characters are available.
2862
2863* (Unix version): Link with -lGL, if it exists, to support linking with gold or
2864  GNU ld --as-needed (Debian bug #615781).
2865
2866* img.c:
2867
2868  + Fix code typo for IMG_API_VERSION == 0 case.
2869
2870  + Fix code typo in code used when IMG_HOSTED isn't defined.
2871
2872* doc/TODO.htm: Remove entries which have now been done.
2873
2874* (Microsoft Windows version): aven: We now include all the available
2875  translations for messages from wxWidgets, which means that standard widgets
2876  will appear translated where available even if Survex messages aren't
2877  translated.
2878
2879Changes in 1.1.15 (2010-10-15):
2880
2881* aven:
2882
2883  + In the cavern log window, change the "Rerun" button to "Reprocess" to
2884    follow terminology in manual and elsewhere.  Fixes ticket#15.
2885
2886  + When displaying output from cavern, don't update the window after every
2887    line, but only when we don't have data from cavern pending.  Hopefully
2888    addresses ticket#12.
2889
2890  + If we aren't using GL_POINTS for blobs, draw them using a series of
2891    abutting lines rather than with gluDisk which is faster and gives a
2892    consistent shape.
2893
2894  + Check whether blobs and crosses actually render correctly as points/point
2895    sprites, and if they don't, fall back to drawing them with lines.  The
2896    best method is cached on disk, and rechecked automatically if the graphics
2897    hardware is changed or the drivers upgraded.
2898
2899  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
2900    though, so we still enable USE_FNT by default).
2901
2902  + Don't offer "All files" wildcard in presentation save dialog.
2903
2904  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
2905    more places.
2906
2907  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
2908    when running cavern from aven.  Fixes ticket#11.
2909
2910* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
2911
2912* diffpos: Handle files with duplicate labels in better - extend generates
2913  duplicate labels when it breaks a loop.
2914
2915* Enable eswap-break testcase now that diffpos handles duplicate station names.
2916
2917* New v7 of .3d format which stores survey dates as number of days since
2918  January 1st 1900, so we now support dates from 1900-2078 (rather than
2919  1970-2037) with a smaller file size.  The img API is now versioned - you
2920  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
2921  gives the survey dates in days in days1 and days2 instead of as time_t
2922  values in date1 and date2.  Fixes ticket#14.
2923
2924* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
2925  former has been the canonical name for some time, with www.survex.com just
2926  redirecting to it.
2927
2928* (Unix version): Use unlocked file I/O if available, which can be much faster
2929  in some cases (we don't need the locking as we don't do multithreaded file
2930  I/O).
2931
2932* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
2933  headers.
2934
2935* (Mac version): buildmacosx.sh now works again.
2936
2937* Most tests weren't actually running any testcases (looks like a sh
2938  portability issue).  This is now fixed, and fortunately all tests still pass.
2939
2940* Include the extra .isl translation files for Innosetup in the source archive.
2941
2942Changes in 1.1.14 (2010-07-26):
2943
2944* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
2945
2946* aven:
2947
2948  + After processing survey data, if there were warnings or errors, add a
2949    "Rerun" button to allow easy reprocessing after fixing problems.  If there
2950    were only warnings, also add an "OK" button to allow moving on to viewing
2951    the processed survey data (fixes ticket#13).
2952
2953  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
2954
2955  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
2956    not the ': ' after), and to make the title for the terminal the
2957    warning/error message.  Avoid false positives by checking that '<line>' is
2958    a number.
2959
2960  + Don't double escape the contents of href and target in links in the cavern
2961    log window.
2962
2963  + Improve handling of the splitter window, fixing behavioural glitches in
2964    various cases.
2965
2966  + Highlight stations matching any current search when a file is loaded.
2967    (ticket#9)
2968
2969  + (Mac version): Fix build issue due to Mac OS X polluting the global
2970    namespace with its own "Point" class.
2971
2972  + (Unix version): The Gnome print dialog has its own preview window so
2973    suppress ours if using the Gnome one.
2974
2975  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
2976
2977  + (Microsoft Windows version): Fix handling of a double-click on the survey
2978    tree when built with wxWidgets >= 2.8.11.
2979
2980* cavern: Report relevant file and line number for three warnings which didn't
2981  give them before.
2982
2983* (Unix and Mac versions): configure: Update the wx-config probing code -
2984  wxmac-config etc aren't present with newer wxWidgets versions so there's no
2985  point looking for them now.
2986
2987* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
2988  for easy installation.  Update it to work with the latest Survex versions
2989  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
2990  private wxWidgets, use 2.8.11 not 2.7.0-1).
2991
2992* manual:
2993
2994  + Correctly capitalise "GTK".
2995
2996  + Note that on Linux we only regularly test builds with the GTK+ version
2997    (change taken from 1.0).
2998
2999* Fixed the cad3d man page, which was an empty file in 1.1.13.
3000
3001Changes in 1.1.13 (2010-06-16):
3002
3003* Say "wxWidgets" instead of "wxWindows" consistently.
3004
3005* img.c: Fix small memory leak (filename_opened member).
3006
3007* cad3d, aven: Fix export to SVG when a label contains a '%' character.
3008
3009* aven:
3010
3011  + wxWidgets 2.6.0 or newer is now required.
3012
3013  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
3014    work but hasn't been tested recently (all packaged versions of wxWidgets
3015    seem to be Unicode now).
3016
3017  + Fix potential uses of uninitialised variables which may have been causing
3018    occasional glitches when loading a file on start-up.
3019
3020  + Improvements to the handling of the font used for plotting labels and other
3021    text on the survey pane:
3022
3023    - Loading the font file is more efficient.
3024
3025    - Character spacing is improved.
3026
3027    - Default font is now anti-aliased.
3028
3029  + "About" dialog:
3030
3031    - Add "Copy" button to copy the system info to the clipboard for easier
3032      bug reporting.
3033
3034    - List OpenGL extensions last, since there are usually lots of them with a
3035      modern gfx card.
3036
3037    - Fix 100% CPU usage while the "About" dialog is open.
3038
3039  + Processing .svx files:
3040
3041    - Passing a .svx file on the command line now works better.
3042
3043    - Put the survey data log window in a splitter in the usual frame rather
3044      than opening a separate frame for it.
3045
3046    - Auto-scroll the log window until we've reported a warning or error.
3047
3048    - Fix small memory leak.
3049
3050  + The presentation filename now defaults to using the basename of the
3051    currently loaded dataset, but we always prompt before we first save with
3052    such a name.
3053
3054  + Reduce memory usage when saving a screenshot.
3055
3056  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
3057    persist the window size (and maximised or fullscreen state) between
3058    invocations.
3059
3060  + Fix reporting of OpenGL errors.
3061
3062  + Fix glitches when tilting while looking East.
3063
3064  + Added Portuguese and Slovak translations of wxWidgets messages.
3065
3066* Documentation:
3067
3068  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
3069
3070  + Drop the "alternative manual formats" self-extracting zip file - people
3071    will generally just want one of the formats, so downloading several
3072    together isn't very useful.
3073
3074  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
3075
3076  + GPL.htm: Replace HTML version of licence with a link to the version on
3077    the FSF website.
3078
3079  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
3080    low level to be of interest to non-developers, and developers can look at
3081    the source code.
3082
3083* (Unix version): configure: New preferred name for specifying wx-config script
3084  is WX_CONFIG.  WXCONFIG still supported for compatibility.
3085
3086* (Linux version): Source RPM package dropped as you can just build an RPM
3087  package from the source tarball.
3088
3089* (Microsoft Windows version): The installer is now created with a newer
3090  version of InnoSetup, which gives a 10% smaller download.
3091
3092Changes in 1.1.12 (2007-02-07):
3093
3094* aven:
3095
3096  + Remember the window size or maximised/fullscreen state between invocations.
3097
3098  + Add options dialog to "Export" similar to the one for "Print".
3099
3100  + The "number of pages required" in the print dialog now updates when you
3101    change what is to be shown (underground legs/surface legs/station
3102    names/crosses).
3103
3104Changes in 1.1.11 (2006-11-25):
3105
3106* Updated Czech, Spanish, and Slovak translations.
3107
3108* (MacOS X version): Assorted OS X specific tweaks and fixes.
3109
3110* aven:
3111
3112  + Pick a smaller and clearer font for labels.
3113
3114  + Fix character spacing.
3115
3116  + Tweak display of bearing and elevation angles to look nicer with
3117    proportional fonts.
3118
3119  + Use the title from the 3d (or plt, etc) file for the window title
3120    rather than the filename.
3121
3122  + Show distances to 2 decimal places rather than the nearest integer.
3123
3124  + Only consider underground legs when calculating the depth bands and
3125    depth colouring.
3126
3127  + Add "Colour by Error".
3128
3129  + Add entry for "white" in date and error keys.
3130
3131  + When setting the view to a single point, don't change the scale.
3132
3133  + If reloading the same file, don't change the view
3134
3135  + Fix filetypes selector in open dialog.
3136
3137  + Fix the charset we use for aven in certain cases.
3138
3139  + Call msg_init before using msg_lang or it won't ever be set!
3140
3141  + Pass wx the full language code to initialise the C library locale.
3142
3143  + Fix bug in generating prefix tree view which could lead to a bogus
3144    leading dot on some survey names (bug probably introduced in 1.1.10).
3145
3146  + "New Presentation" now ensures that the side panel is open
3147
3148  + Fix updating of cached opengl lists when the view is reset to the
3149    default.
3150
3151* Ignore LANG if it starts with a digit to avoid problems with bogus value for
3152  LANG which AutoCAD installation seems to set on MS Windows.
3153
3154* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
3155  specified.  Either/both can be set to ":".
3156
3157* dump3d: Report unknown (to dump3d) codes returned by img.
3158
3159* img library: Flag all stations as underground in the old "ASCII" .3d format.
3160
3161Changes in 1.1.10 (2006-07-14):
3162
3163* aven: Clicking on a survey name in the survey tree now highlights it in
3164  the map view.  Double-clicking zooms the view to show the clicked survey
3165  highlighted.  Clicking the root clears the highlighting and double-clicking
3166  the root restores the default view.  To expand/collapse a branch, click
3167  on the "[+]" or "[-]" icon to the left of the survey name.
3168
3169* aven: The measuring line can now measure to anywhere in plan or elevation
3170  view (not just to a station!)  In plan view the horizontal distance and
3171  bearing are shown, while in elevation view the vertical distance is shown.
3172
3173* aven: Moving the mouse over a station in the survey view now highlights
3174  that station in the survey tree (though it may not be visible if the
3175  survey(s) it is in aren't expanded).
3176
3177* aven: Clicking on a station to centre the view now moves the mouse pointer
3178  to the new location of the station (except on Mac OS X where this isn't
3179  allowed).
3180
3181* aven: Fix which presentation toolbar buttons are shown as depressed.
3182
3183* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
3184
3185* vim files are now installed with the correct paths (bug introduced in 1.1.9).
3186
3187Changes in 1.1.9 (2006-07-04):
3188
3189* (Unix version): Install desktop files for aven and svxedit contributed to the
3190  Ubuntu package by Phil Bull, and corresponding pixmaps.
3191
3192* Fix img to filter out cross-sections which don't match the subsurvey (if
3193  specified).  The API now returns img_XSECT_END to mark the end of a
3194  passage rather than setting a flag on the last img_XSECT of the passage.
3195
3196* Enhance integration with the vim editor - this can now colour .err files, run
3197  cavern from vim and parse error output, and run aven from vim.  Tweak the
3198  existing vim mode for .svx files to fix a few minor bugs and add support for
3199  the new "*data passage" style.
3200
3201* aven: fix drawing of the "blob" end of the measuring line on graphics cards
3202  which can't draw large enough blobs for us.
3203
3204* aven: sort out confusion about what encoding everything is in which means
3205  that the distance measured by the measuring line actually gets displayed
3206  and also fixes problems with empty menu items in non-English locales in
3207  some cases.
3208
3209* aven: redraw grey background after a menu is closed over the aven window
3210  with no survey loaded.
3211
3212* aven: fix bug which caused printing to crash (introduced in 1.1.8).
3213
3214* aven: avoid crash on some machines when opening "About" dialog before having
3215  loaded a survey.
3216
3217* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
3218
3219* (Unix version): aven: Fix character set handling of cavern output.
3220
3221* cavern: Report an error if a cross-section is specified for a station which
3222  doesn't exist.
3223
3224* Updated French and Italian translations.
3225
3226* (Unix version): aven: Fix "Can't open message file `en_US' using path
3227  `${prefix}/share/survex'" error.
3228
3229* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
3230  (doesn't affect Survex itself, but other applications which use img.c should
3231  update their copy).
3232
3233* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
3234  and later are caught by configure, whereas older wx versions are caught when
3235  trying to compile).
3236
3237Changes in 1.1.8 (2006.06.30):
3238
3239* Drop support for building with wxWidgets versions prior to 2.4.0
3240  (which was released on 2003-01-07).
3241
3242* aven: Printing through aven now uses settings from the "[aven]" section
3243  of print.ini, and support for hierarchical sections (using "like=")
3244  has been disabled.
3245
3246* aven: Change mouse actions to be compatible with those in Survex 1.0.
3247  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
3248  left drag is now smart about not rotating and zooming at the same
3249  time.
3250
3251* aven: Highlighting stations now happens as you type, and pressing
3252  "Enter" or clicking the "Find" button now pans and zooms to show the
3253  highlighted stations.
3254
3255* aven: Left-clicking away from a station now cancels measuring line.
3256
3257* aven: Setting view to North, South, East, or West is now animated like
3258  the tilt from plan to elevation.
3259
3260* aven: Fix presentation saving to also write "." for decimal points and
3261  presentation loading to accept either "." or ",".
3262
3263* (Unix version): aven: Add text for all toolbar items so that aven
3264  will work with the Gnome desktop preference for displaying toolbars as
3265  icons with text or just text (wxWidgets needs fixing first though).
3266
3267* (Unix version): aven: Remove the ability to detach the menu bar (yell
3268  if you actually used it and I'll restore it!)
3269
3270* aven: Add "all survey files" option to the "open file" dialog.
3271
3272* (MS Windows version): aven: Fix cursor keys to pan survey.
3273
3274* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
3275
3276* (MS Windows version): Fix installer to work on Windows 2000 or XP if
3277  run by an unprivileged user.
3278
3279* (MS Windows version): Upgrade to the latest version of InnoSetup (the
3280  installer builder we use) and include new installer translations for
3281  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
3282
3283* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
3284  translations of messages for wxWidgets (the GUI library we use).
3285
3286* aven: Disable "Highlight exported points" if there aren't any.
3287
3288* Updates to French translation from Michel Bovey.  Also updates to German,
3289  Italian, Catalan, Spanish, and Romanian translations.
3290
3291* (Unix version): test suite: fix smoke test to pass even without X running
3292  (it was meant to but the code had a bug).
3293
3294* aven: Check if OpenGL is available and exit cleanly with a helpful error
3295  if it isn't.
3296
3297* (Unix version): aven: Fix --help and --version to work without a working
3298  X display (provided it's built with wxWidgets 2.5.1 or newer).
3299
3300* aven: Automatically select the presentation tab of the notebook when the user
3301  selects "New Presentation" or "Open Presentation".
3302
3303* aven: Fix "Delete" in the presentation list to not get passed on (and so not
3304  reset to default view as well).
3305
3306* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
3307  empty.
3308
3309* aven: Fix Cursor Up and Down in the presentation list to move the highlight
3310  up and down instead of being passed on and moving the survey.
3311
3312* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
3313  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
3314  Safari 2.0.3, and InkScape 0.42.
3315
3316* aven: Put a 5mm border around exported SVG files to allow for station markers
3317  and non-zero width lines.
3318
3319* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
3320  was turned on.
3321
3322* aven: Actually close the file we're exporting which fixes problems with it
3323  not always being fully written.
3324
3325Changes in 1.1.7 (2005.10.18):
3326
3327* cavern: Add validity checking for dates in *date commands (with feature
3328  test in testsuite).  A date entered as just "year" or "year.month" now
3329  becomes a date range for the relevant period (previously it became a single
3330  date near the middle of that period).
3331
3332* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
3333  with MS Windows).
3334
3335* extend: Default output name for a file called input.3d is now input_extend.3d
3336  rather than just extend.3d (which was annoying if you wanted to extend
3337  several surveys in the same directory).
3338
3339* aven: OpenGL 2.0 always includes support for point sprites so rework
3340  our check for them to include that knowledge.
3341
3342* aven: Regenerate depth bar if user switches to/from metric units.
3343
3344* aven: Don't clear the "there" mark just because the mouse pointer has
3345  moved off a station.
3346
3347* aven: When processing a .svx file, put the resultant .3d file in the
3348  same directory (since that's where we then try to load it from).
3349
3350* aven: Fix labelling of date colouring on 32 bit platforms.
3351
3352* aven: If "colour by date" is on and we load a survey with no date info
3353  (or all surveyed on the same date) then set "colour by none".
3354
3355* aven: Make the error dialog modal and remove a signal handler once it
3356  has fired to prevent endless (or seemingly endless) cascades of error
3357  dialogs.
3358
3359* aven: Enforce a minimum object volume diameter of 1m to avoid problems
3360  if a survey file with only one station in is loaded.
3361
3362* aven: Fix problems with indicators disappearing when we're drawing
3363  blobs and/or crosses the slow (but always supported) way.  (Problem
3364  introduced in 1.1.6).
3365
3366* (Unix version): aven: Really stop setting extra toolbar margin when using
3367  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3368  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3369
3370* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3371  we've been compiled with, and which GTK+/Motif version where appropriate.
3372
3373* (Unix version): Fixed build on Fedora Core 3.
3374
3375* documentation: Updates to 3d file format specification from Mike McCombe.
3376
3377Changes in 1.1.6 (2005.10.10):
3378
3379* (MS Windows version): Distribution is about a third smaller than 1.1.5
3380  (mostly because mingwm10.dll is no longer required).
3381
3382* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3383  it, showing cavern's output in a window (with errors and warnings clickable
3384  to load the offending file into an editor), and then loading the resulting
3385  3d file.
3386
3387* aven: Added "Colour by Date" option.
3388
3389* aven: Disable "Colour by Depth" option if there's no elevation variation.
3390
3391* aven: Don't crash if trying to load a survey with no elevation variation.
3392  Instead turn off depth colouring.
3393
3394* aven: Export as HPGL added.
3395
3396* aven: Improved update of mouse coordinates and measuring line (thanks to
3397  Martin Green).
3398
3399* aven: Show the coordinates of either the mouse pointer or the nearest
3400  survey station to it (if there is one near enough).  Showing both was
3401  confusing and meant the status bar overflowed on smaller displays.
3402
3403* aven: When printing an extended elevation, don't show bearing and elevation.
3404
3405* aven: Don't lock "flat" surveys which aren't extended elevations - a
3406  flat survey with LRUD data isn't flat any more!
3407
3408* aven: When we have to draw blobs and crosses the slow way (because the
3409  graphics hardware doesn't support the fast way), draw them so that they
3410  should appear at the correct depth into the 3D scene instead of on top
3411  of everything else.
3412
3413* aven: Make "play presentation backwards" icon green to match the other
3414  presentation icons.
3415
3416* (MS Windows version): aven: Mouse clicks on the survey view now set the
3417  keyboard focus there.
3418
3419* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3420
3421* (MS Windows version): aven: Fix redrawing of measuring line.
3422
3423* cavern: Store dates for img_XSECT.
3424
3425* cavern: Fixed small one-off memory leak if you specify -o more than once.
3426
3427* (Unix version): Check environmental variable LC_MESSAGES when deciding what
3428  language to use for messages.
3429
3430* (MS Windows version): "Print" on a 3d file now prints through aven rather
3431  than the separate printer driver (Unix has done this for some time).
3432
3433* Removed old printer drivers.
3434
3435* img library: When creating a 3d file, ignore img_XSECT if we've been asked
3436  to write a file format version which doesn't support it.
3437
3438Changes in 1.1.5 (2005.09.20):
3439
3440* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3441
3442* aven: Make blobs round like they are in Survex 1.0.
3443
3444* aven: If the graphics drivers don't support drawing blobs using OpenGL
3445  point markers, fall back to drawing filled circles.
3446
3447* aven: If the graphics drivers support it, draw crosses as texture mapped
3448  OpenGL point markers which is much faster.
3449
3450* aven: Cross size increased to match Survex 1.0.
3451
3452* aven: We must update which blobs are displayed if display of surface or
3453  underground legs is toggled.
3454
3455* cavern: Fix handling of a *solve followed by survey data, none of which is
3456  attached to the previous data.
3457
3458* cavern: Fixed "No survey data" error when a *solve is followed by another
3459  *solve (or the implicit solve at the end of processing) with no data between
3460  them.
3461
3462Changes in 1.1.4 (2005.09.19):
3463
3464* aven: Added Aven's icon to the "About" dialog.
3465
3466* aven: Use localised character for the decimal point (e.g. "," in most
3467  continental European countries).
3468
3469* aven: Previously the survey tree would get focus and then take keypresses
3470  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
3471  operate on the cave, and transfer the input focus across when we do.
3472
3473* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3474
3475* aven: Speed up intialisation by delaying creation of OpenGL lists until
3476  they're needed.
3477
3478* aven: Added Mark Shinwell's bounding box with shadow of the survey.
3479
3480* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3481
3482* aven: Reworded "Restore Default Settings" as "Restore Default View".
3483
3484* (Unix version): aven: Set sensible default margins for printing and preserve
3485  any margin values the user specifies between runs (previously margins
3486  defaulted to 0 each time aven was run).
3487
3488* Documentation: Document *DATA PASSAGE in the manual.
3489
3490Changes in 1.1.3 (2005.09.07):
3491
3492* (Microsoft Windows version): Fixed build problems.
3493
3494* cavern: Allow OMIT character (-) for left/right/up/down.
3495
3496* aven: Remove an unnecessary menu separator.
3497
3498* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3499
3500* aven: Make the tooltip for "Hide" show the number of found stations.
3501
3502* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3503
3504* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3505  when there's a presentation loaded.
3506
3507* aven: Make entrances green in side panel tree list to match green blobs used
3508  in cave view.
3509
3510* aven: Don't show surface labels if we're not showing surface data, etc.
3511
3512* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3513  make "Space" the key for this.  Keep Return working "Stop Rotation" so
3514  existing users are happy, but don't advertise it.
3515
3516* aven: Normalise filename by adding any extension used, and use the normalised
3517  filename for file history and window title.
3518
3519* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3520  as the toolbar buttons already have a sensible margin - the extra margin is
3521  only needed with GTK1.2.
3522
3523* aven: Fix handling of plumb legs in tube model.
3524
3525* aven: Fixed swapped L and R in tube model.
3526
3527* extend: Preserve UD cross-section information in extended elevation.
3528
3529* extend: Add new messages for John Pybus' enhancements.
3530
3531Changes in 1.1.2 (never formally released):
3532
3533* Added support for LRUD data in .svx files, in .3d files, and aven can
3534  now load and display it on screen and on printouts.  The ability to "fake"
3535  LRUD data in aven is gone for now but will reappear in some form later.
3536
3537* cavern: Removed support for writing Chasm's 3dx format.  We're going to
3538  fold any desirable missing chasm functionality into aven.
3539
3540* aven: Rearranged mouse actions as discussed on the mailing list.  Added
3541  cursors for each different mouse action to help the user learn what each
3542  does.  Also added cursors for the "compass" and "clino" as well as the
3543  scalebar to suggest to the user that they can be dragged to change the view.
3544
3545* (Unix version): aven: Don't segfault if LANG isn't a known language.
3546
3547* tests/smoketest.tst: If X windows is running, check that we can run aven
3548  with --help and --version.
3549
3550* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3551  no results are listed for it.  This revealed that there was a "newline" test
3552  which should have been called "badnewline", and was a broken testcase too!
3553  Fixed all these problems.
3554
3555* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3556  and omitted forward compass/clino readings in Compass DAT files.  Added
3557  a feature test for this to the testsuite.
3558
3559* It no longer makes sense to have an option not to build aven or to build aven
3560  without OpenGL so remove old machinery for this from configure and the
3561  sources.
3562
3563* (Unix version): configure: Check if "-lXxf86vm" is needed.
3564
3565* configure: Better output for strcasecmp test.
3566
3567* aven: Fix crosses to work much better.  Not a total fix - their position
3568  in the Z buffer isn't correct and they're rather slow to plot.
3569
3570* aven: Don't regenerate the hittest grid every time the mouse moves while
3571  animating, which solves the mysterious pausing effect (thanks go to Martin
3572  Green for spotting this!)  Also clear all the status bar coordinates when
3573  animating.
3574
3575* aven: Sort out clashing menu shortcuts in some languages.
3576
3577* aven: Fixed compilation problem on x86_64
3578
3579* SPUD: Pruned out stuff which has been done or which is not actually relevant
3580  to this branch.
3581
3582* Merge various changes from 1.0 branch:
3583
3584  + aven: Port over "printing from aven" functionality.
3585
3586  + aven: Port over "export as" functionality,
3587
3588  + Add David Loeffler's vim mode for .svx files.
3589
3590* aven: Fix check for whether a label is behind us in perspective view.
3591
3592* aven: Don't use an opengl list for drawing the indicators - we typically make
3593  a new list each time we plot them anyway.
3594
3595* Remove lingering traces of support for RISC OS and pre-386 MSDOS
3596
3597* aven: Set icon on non-Windows platforms too.  This means that with
3598  WindowMaker on Unix you get an icon on the AppIcon by default.
3599
3600* configure: Update wxWindows checks to handle newer wx versions.
3601
3602* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3603  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
3604  for anyone building from CVS).
3605
3606* acinclude.m4: Quote macro name for fix autotools warning.
3607
3608* Documentation: "tilt up" is "'" not ",".
3609
3610* aven: Add support for mousewheels (to tilt the cave).
3611
3612* aven: Fixed twisted transitions to and from pitches in certain cases.
3613
3614* aven: Pick a sensible initial window size when the user's desktop is spread
3615  over more than one monitor (works best with wx2.5 or newer, but try to do
3616  better with wx2.4 or earlier as well).
3617
3618* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3619  contents being visible before any survey is loaded.
3620
3621* aven: Allow a coloured texture to be used
3622
3623* aven: Don't initialise until we have data (to the user, this means the window
3624  is default colour (grey for most systems) not black until a survey is
3625  loaded).
3626
3627* aven: Fixed weird "shadowed" icons.
3628
3629Changes in 1.1.1 (2004-10-06):
3630
3631* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
3632  startup.
3633
3634* aven: Delay loading the bitmap for the "About" dialog until it is first
3635  needed.  We want start up to be as quick as possible.
3636
3637Changes between 1.0.32 and 1.1.0 (never formally released):
3638
3639* NOTE: Survex 1.1.X releases are development snapshots made available for
3640  the purposes of allowing wider testing and getting more user feedback.  Once
3641  the code has stabilised the version number will be raised to 1.2.0.
3642
3643* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3644  you're using Windows 95 - these can be obtained from:
3645  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
3646
3647* aven: Solid passages - passage dimensions are currently inferred from
3648  the leg length (pretty effective as you can measure longer legs in
3649  larger passages).  Use of real LRUD data coming soon...
3650
3651* aven: Depth colouring is now continuously varying.
3652
3653* aven: Colour by depth can now be turned off (and there's the start of a
3654  framework for properly implementing colour by date, error, etc).
3655
3656* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3657  match (? matches any character, * matches any number of characters).
3658
3659* aven: We now use the status bar for coordinates, distances, etc to make
3660  better use of screen space.
3661
3662* aven: Full screen mode (F11).
3663
3664* aven: Perspective view.
3665
3666* aven: Context sensitive cursor shape - needs more work.
3667
3668* aven: Mouse actions changed (hopefully they're now more natural, but
3669  you may find the change disorientating - feedback wanted on this).
3670
3671* aven: Added "presentations" which allow you to set up fly-through paths
3672  and load/save/run them.
3673
3674* aven: A presentation can be exported as a movie file.
3675
3676* aven: Added Save screenshot facility.
3677
3678* aven: Depth fogging option.
3679
3680* aven: Added Smooth Lines option.
3681
3682* aven: Added Textured Walls option.
3683
3684* aven: If a survey has surface legs but no underground legs, default to
3685  showing the surface legs.
3686
3687* cavern: Dates given to *date are now stored in the 3d file.
