[a30f7d0]1Changes in 1.4.5 (2023-06-29):
[1a67f93]2
3* aven: Fix rendering of crosses when drawn as sprites.  Reported by echarlie.
4
5* (macOS version): aven: Fix crash in export dialog.  Fixes #133, reported by
[a30f7d0]6  rixyane.  Thanks to Wookey for testing.
[1a67f93]7
8* manual: Expand docs on connecting to Compass data.
9
10* Minor translation updates.
11
[269106c]12Changes in 1.4.4 (2023-02-03):
13
14* aven: Fix red line in clino background to be grey (this was introduced in
15  1.4.3 and was a debugging change accidentally left in).
16
17* aven: Accept weird .3d files from Therion which have empty components in
18  station names.  That's not really valid by Survex's definition of station
19  names, but it's not very helpful to reject such files, so just disable the
20  checks that were rejecting this.
21
22  The result is empty entries in the survey tree, but I don't see what we can
23  really do that's better than that.
24
25  Reported by Vasily Vl. Suhachev.
26
27* aven: Make it more obvious you can enter a custom scale by adding a "..."
28  entry to the scale combobox - selecting this clears the value and gives focus
29  to the combo box text entry. This control has always supported clicking to
30  enter a custom scale, but there wasn't really any indication that this was
31  possible before.  Partly addresses #132, reported by Eric C. Landgraf.
32
33* aven: Force export window to resize when the export format is changed as
34  different controls are shown depending on the export format.
35
36* aven: Right-align tilt spin control value in print/export dialog to match the
37  bearing spin control.
38
39* aven,survexport: Add ability to export as Survex 3d which is useful as you
40  can filter to a subset of surveys, filter out splays, convert from other
41  formats the img library can read, etc.  This feature is a bit rough and ready
42  currently but please report issues.
43
44* dump3d: Add --legs option which converts MOVE and LINE to a single LEG line
45  per leg with the from and to coordinates.  Tools which parse dump3d output
46  should find this easier to process as it avoids having to track a "current
47  position".
48
49* Update manual to have a complete list of quantities which *calibrate accepts.
50  Reported by echarlie
51
52* cavern.tst: Fix testsuite to work with SOURCE_DATE_EPOCH set.
53
[fcf3d2e]54Changes in 1.4.3 (2022-05-17):
[4c0900b]55
[4659b8a]56* aven: Much improved support for HiDPI monitors on all platforms.
[4c0900b]57
58* aven: When started without a file make sure the window has focus so menu
59  accelerators and shortcuts work without clicking on the window.
60
61* aven,survexport: DXF export now puts splays in a separate layer and uses a
62  dotted linetype for them.  Patch from echarlie, see #60.
63
64* Improved survexport man page to include command line options and a short
65  note about DXF export.  Patch from echarlie.
66
[4659b8a]67* Minor translation updates.
[4c0900b]68
[4659b8a]69* (Unix version): aven: Fix handling of EGL-based wxGLCanvas (which wxGTK 3.1.5
70  has).  Fix a build failure and don't force X11 (as the EGL-based wxGLCanvas
71  works on Wayland).
[4c0900b]72
73* (MacOS version): aven: Fix hang on startup without a file.  Fixes #120,
74  reported by Enrico Fratnik.
75
[fcf3d2e]76* (Microsoft Windows version): Now using wxWidgets 3.1.6 (was 3.0.5).
77
[4659b8a]78* img library: Support reproducible builds which create .3d files by not
79  embedding a timestamp if environment variable SOURCE_DATE_EPOCH is set.
80  Requested by Martin Budaj.
81
[a33237fd]82Changes in 1.4.2 (2022-02-25):
[d2b22b1]83
84* aven: Fix to be compatible with FFmpeg 5.0.
85
86* Improve docs for *cs and *declination.
87
[48d5a6f]88* cavern: Fix "*declination auto" not to crash when built with PROJ < 8.1.0.
89  Bug introduced in 1.4.0.
90
[a33237fd]91* cavern: For each `*declination auto` command cavern now reports an "info"
92  message showing the range of calculated declination values and the dates at
93  which the ends of the range were obtained, and also the grid convergence
94  (which doesn't vary with time).  Fixes #92, reported by Rob Eavis.
95
[48d5a6f]96* cavern: If any of the N-S, E-W or U-D ranges includes an anonymous station
97  then also report the range in that direction excluding anonymous stations.
98  Patch from Thomas Holder.
99
100* cavern: The error from a bad `*cs custom` command now highlights the quoted
101  string properly.
[d2b22b1]102
[a33237fd]103* cavern: "FIX command with no coordinates - fixing at (0,0,0)" is now an
104  "info" rather than a "warning".  It's not really reporting a problem and the
105  ability to omit the coordinates is a deliberate feature.  It is useful for
106  the user to know where the "*fix" without coordinates is if they want to
107  change the survey to be in real coordinates, so an "info" diagnostic is a
108  good fit.  This also means aven will no longer stay on the log view after
109  processing a dataset which fixes without coordinates.
110
111* cavern: If "*fix" is used twice with no coordinates we no longer say
112  "FIX command with no coordinates - fixing at (0,0,0)" right before:
113
114  error: Already had FIX command with no coordinates for station "x"
115
[d2b22b1]116* cavern: Include errors in Compass .mak files now report the error in the line
117  where the included filename is actually specified.
118
119* cavern.tst: Add test coverage for warnings for *entrance and *export with
120  a station which doesn't exist otherwise.
121
[a33237fd]122* aven/survexport: Change JSON export to be valid JSON.  This means the output
123  has changed incompatibly, but it wasn't valid JSON before which suggests
124  nobody was actually successfully using it. Fixes #128, reported by Pawczak.
125
[48d5a6f]126* aven.tst: Skip one testcase on macos as it seems to hang, at least when
127  running on the Continuous Integration system.
128
[a33237fd]129* (Microsoft Windows version): The installer is now generated with a much
130  newer version of Innosetup.  Most notably, it now supports installing as a
[812a8d7]131  non-admin user.  This also means Microsoft Windows Vista is now the minimum
132  supported version but 2000 and XP are both many years out of support anyway.
[a33237fd]133
134* (Microsoft Windows version): The coordinate system database for PROJ is
135  now included so "*cs" now works (broken since 1.4.0).
136
[d2b22b1]137* Chinese translation updates from Qingqing Li.
138
[d8f00a9]139* Building from source now requires a compiler with support for C99.  C99
140  seems to be universally supported by compilers now so we don't expect this to
141  inconvenience anyone.
142
[570b57d]143Changes in 1.4.1 (2021-11-08):
144
145* This release should work with any PROJ version >= 6.2.0.
146
147* cavern.tst: Fix to actually run tests when building outside the source
148  tree.  Previously files for testcases weren't found, and tests were skipped
149  with a warning, which lead to 1.4.0 being released with two failing testcase.
150  Fix to find the files, and make not finding them an error.
151
152* cavern.tst: Fix testcases gpxexport and require_fail which were failing
153  in 1.4.0.
154
155* 3dformat.htm: Document that coordinate system can be ESRI:<number>.
156
[67f9739]157Changes in 1.4.0 (2021-11-06):
[3b69f29]158
159* New release series to mark that Survex now uses the new PROJ API, and
[cccc545]160  requires PROJ >= 7.2.0.  Survex 1.2.x will continue to support PROJ < 8
161  (and won't support newer PROJ versions).  Fixes #102, reported by Bas
162  Couwenberg.
[3b69f29]163
164  Due to these changes, PROJ will now convert directly between coordinate
165  systems where it knows how to, instead of always converting via WGS84.
166  This means conversions may now be more accurate in some cases, and you may
167  notice station coordinates changing - these should be for the better.
168
169  Also, the vertical datum is now taken into account automatically, and
[e91c656]170  terrain data now aligns much better vertically with surveys.  Fixes #56.
[3b69f29]171
172* aven: Clicking and holding the left mouse button on the compass or clino,
173  then (while still holding) clicking the right button no longer causes a
174  wxWidgets assertion to fail.  Reported by echarlie.
175
176* img library: Rewrite certain proj strings when reading 3d files for
177  better compatibility with newer PROJ versions, where use of proj
178  strings is strongly discouraged.
179
180  `+init=epsg:` followed by a code number is rewritten to `EPSG:`.
181
182  `+init=esri:` followed by a code number is rewritten to `ESRI:`.
183
[67f9739]184  The proj strings which cavern used to put in 3d files for UTM zones and
185  S-MERC are rewritten to `EPSG:` follow by the appropriate code number.
[3b69f29]186
187* Also install survex.lang for gtksourceview 4. Fixes #125, reported by Martin
188  Green.
189
190* Fix missing data style in interleaved example in manual.  Reported by
191  echarlie.
192
193* Use jw from docbook-utils instead of sgmltools-lite to process the manual.
194  The sgmltools-lite homepage says it's no longer being developed, and suggests
195  docbook-tools (which Debian packages as docbook-utils) as a replacement.
196
197* doc/HACKING.htm: Update Debian packages to install
198
[67f9739]199* doc/HACKING.htm: Update details of setting up mingw cross-build environment.
200
[3b69f29]201* Add simple tests for GPX and KML export.
202
203* Expand cavern testcase csbad.
204
205* cavern.tst: Parse warning/error counts more robustly.  Previously we'd get
206  confused if the final line just contained an integer, e.g. if we end listing
207  stations not attached to a fixed point.
208
[738af38]209Changes in 1.2.45 (2021-03-09):
210
211* Avoid undefined signed shifts in 3d file handling.  Survex itself is only
212  affected on big-endian platforms (so most Linux machine, Microsoft Windows,
213  and current Macs are all OK), but this also affects the img library on all
214  platforms when used in standalone mode as it is in other programs.  Fixes
215  #119, reported by Matěj Plch.
216
217* aven:
218
219  + When reading cavern output for the log window, we need special handling
220    for the case when a chunk of output ends mid-way through a UTF-8
221    sequence.  Previously we lost the first byte of the sequence in this
222    case (and would then show it as an invalid character), but now it is
223    handled correctly.  In practice, most of the cavern log output is ASCII so
224    it's quite possible nobody's ever actually hit this.
225
226* testsuite:
227
228  + Suppress reports of leaks on exit from the LeakSanitiser debugging tool.
229    We know we don't release all memory explicitly on exit since doing so would
230    mean extra work for no reason as the OS reclaims all memory when the
231    process exits.
232
233* Convert OLDNEWS encoding from ISO-8859-1 to UTF-8.
234
[38bc415]235Changes in 1.2.44 (2021-02-10):
236
237* aven:
238
239  + (Microsoft Windows version): Now using wxWidgets 3.0.5 (was 3.0.4).
[f9de21a]240
241* cavern:
242
[66b477f]243  * Add support for quadrant bearings (e.g. N30E).  Patch from echarlie.
244
245  * Report error if angle units are specified for passage dimension.
246    Previously "*units left degrees" and similar were incorrectly quietly
247    accepted.  Spotted by echarlie.
248
[f9de21a]249  * Fix *data with no parameters to keep the current style and reset any state
250    as documented.  Previously it actually instead ignored any survey data
251    until the next *data command with parameters.
252
253  * Fix minor memory leak in *data.  We leaked a single memory allocation on
254    "*data default" or an invalid *data command.
255
256  * Improve test coverage.
257
258* survexport:
259
260  * The check for whether a format supported --elevation, --plan, --bearing and
261    --tilt was inverted.  Reported by echarlie.
262
263  * Fix reporting of export errors on Microsoft Windows.  Reported by Matic Di
264    Batista.
265
266* img library: Fix img_open() when used in other programs.  Patch from Thomas
267  Holder.
268
[66b477f]269* configure: Add wx-config-gtk3 to WX_CONFIG search for Arch Linux.  Patch
270  from Thomas Holder.
271
[f9de21a]272* Improve documentation of interleaved data.  Most notably, we now document
273  that a blank line breaks the current traverse.
274
275* Fix typo in manual ('cypolar' -> 'cylpolar').  Patch from Wookey, fixes #117.
276
277* Chinese translation updates from Qingqing Li.
278
279* Russian translation updates from Vasily Vl. Suhachev.
280
281* French translation updates from Jean-Marc and from Wassil Janssen.
282
283* Bulgarian translation updates from Wassil Janssen
284
[fe8a1b4]285Changes in 1.2.43 (2020-02-28):
286
287* cavern: Update to use v13 of the IGRF model for calculating declinations.
288  This was issued in December 2019 and should give slightly more accurate
289  declinations for surveys made since 2010.
290
291* aven:
292
293  + Fix colouring of "not in loop" when colouring by error.  1.2.42 introduced
294    a bug where surveys not in a loop were coloured as if they had zero error.
295    Fixes #111, reported by Bruce Mutton.
296
297  + Fix handling of grid in export.  The grid was always getting enabled
298    (probably since 1.2.8) even for formats which don't support exporting with
299    a grid.  This resulted in the bounding box being set wrongly for some
300    formats such as SVG, as reported by Richard Knapp on the mailing list.
301
302  + When showing errors processing the survey data we'd previously crash if
303    cavern incorrectly reported an error as being in a column off the end of
304    the line - now we just ignore the error column in this case.
305
306  + Support colouring by survey style ("normal", "diving", "nosurvey", etc).
307
[040c02e]308Changes in 1.2.42 (2019-09-04):
309
310* aven:
311
312  + Allow colouring by horizontal or vertical error.
313
314  + (Unix version): Disable scaling for HiDPI displays with GTK3.  The OpenGL
315    code needs work before this will work usefully, so just disable for now
316    (which simulates how things are when using GTK2).
317
318  + (Unix version): Fix orientation of notebook tabs when build with wxWidgets
319    3.1 development versions.  We want horizontal tab orientation, but were
320    passing a weird flag combination which now results in vertical tab
321    orientation.
322
323* When exporting to a format where we support rotation in the horizontal
324  plane (such as SVG), the rotation was incorrectly applied to cross section
325  data (except for the default rotation of zero).  Fixes #108, reported by
326  Richard Knapp.
327
328* Add a section to the manual covering the command line tools, and what you
329  might still need to use them for.
330
331* Fix compiler warning when building from source with GCC 9.
332
333* Consistently refer to macOS not OS X - Apple have renamed it yet again.
334
335* (macOS version): Revert the workaround for the crash on macOS 10.14.  The
336  bug we were working around is fixed in git ready for wxWidgets 3.0.5 and
337  there's a backported fix in the homebrew wxmac 3.0.4-2 package, which is how
338  we now recommend people install on a Mac.  Closes #101, reported by floho.
339
340* (macOS version): Remove buildmacosx.sh script since installing from homebrew
341  is now the recommended approach.
342
[0957d63]343Changes in 1.2.41 (2019-07-10):
344
345* aven:
346
347  + (Microsoft Windows version): Fix error on startup in the pre-built version
348    of 1.2.39 and 1.2.40.  This is a recurrence of the same issue as affected
349    1.2.33 - this time I've patched out the unnecessary check in wxWidgets
350    which causes this problem so it shouldn't recur again.  Reported by
351    Brian Clipstone.
352
353  + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
354    as I don't have access to a Mac).  Hopefully fixed #101, reported by floho.
355
[d034033]356Changes in 1.2.40 (2019-07-04):
357
358* aven: Draw the measuring line ring with an even shape.  Previously the exact
359  shape of the ring varied slightly depending on the exact coordinates, which
360  could be visually distracting once you noticed it.
361
362* We were casting a function pointer with a bool return type to the same type
363  but with a void return type.  In practice this probably works fine on most
364  platforms, but it's undefined behaviour and also gives a compiler warning
365  with some compilers.
366
367* Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
368  installed.
369
[9fe70e44]370Changes in 1.2.39 (2019-06-29):
371
372* Support versions 5.x and 6.x of the PROJ library we use for handling
373  conversions between coordinate systems.  Reported by Bas Couwenberg
374  in #102, by Richard Knapp in #103 and by Martin Sluka in email.
375
376* (Unix and Mac OS versions): When checking if something is a file or if it is
377  a directory, we no longer treat a symlink as being neither, but instead
378  return an answer based on what the symlink points to.
379
380* aven:
381
382  + Improve handling of hidden splay ends.  Previously, hidden splay ends still
383    served as "targets" for snapping the mouse pointer to, and still got
384    crosses when crosses were enabled.  We don't have a handy flag for "this is
385    the outer end of a splay" and computing that on demand isn't so easy to do,
386    so for now we use the "anonymous station" flag so at least these cases now
387    behave properly for splays to anonymous stations (which is likely to be
388    what people with huge numbers of splays from disto-x, etc are using).  This
389    does mean that anonymous stations on continuation passages will incorrectly
390    also be off when splays are hidden, but that seems an OK trade-off for now
391    and a definite improvement over the previous situation.  The snapping of
392    the mouse pointer was reported by Frank Tully in #105.
393
394  + Fix typo in export UI (CVS should be CSV).
395
396* Documentation:
397
398  + Add CSV to documented list of survexport output formats.
399
400  + Fix *declination syntax synopsis - "auto" is a literal string, not a
401    placeholder.
402
403  + Update PROJ project name and website - the name is now "PROJ" (all caps and
404    no ".4" suffix) and the website is now: https://proj.org/
405
406* Install gtksourceview-3.0 language file so .svx files now get syntax
407  highlighting in gedit and other GtkSourceView-based editors.  Patch
408  from Philip Withnall.  Fixes #98.
409
410* (Microsoft Windows version): The Survex installer doesn't uninstall the old
411  version when you upgrade, but just overwrites it with the new version.  In
412  1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
413  an older version would still have cad3d.exe from that old version.  We now
414  remove any old cad3d.exe left over from a previous install in the same
415  location to avoid confusion.
416
417* Add a few more message translations.
418
419* Fix warnings when built with a C++11 compiler.
420
[66b555d]421Changes in 1.2.38 (2019-03-02):
422
423* cavern:
424
425  + Deprecate MILS as angular units.  Survex has long support MILS as an alias
426    for GRADS.  However, this seems to be a bogus definition of a "mil" which
427    is unique to Survex (except that Therion has since copied it) - there are
428    several different definitions of a "mil" but they vary from 6000 to 6400 in
429    a full circle, not 400.  Reported by Andy Edwards.
430
431  + Fix segfault for *include "".  This isn't useful, but shouldn't crash.  It
432    now reports "file not found" instead.
433
434  + Use isnan() to check for not-a-number.  This is cleaner, more robust and
435    more efficient than formatting the number as a string and checking for
436    "NaN" or "nan" in the result.
437
438* Avoid unused variable warning when compiling from source with modern ffmpeg.
439
440* Drop support for wxWidgets < 3.0.  3.0.0 was released over 5 years ago and
441  should be easily available everywhere by now.  I'm no longer easily able to
442  test with wxWidgets 2.8, and this allows a significant amount of cruft to be
443  removed.
444
445* (Linux version): survex.spec: Fedora have removed gcc from the default build
446  environment so need to explicitly list it in the BuildRequires tag.  See
447  https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
448  information.  Patch from James Begley.
449
[3147062]450Changes in 1.2.37 (2018-11-18):
451
452* aven:
453
454  + Add basic "Colour by Survey" feature.  The colours used aren't currently
455    controllable.
456
457  + Fix export of splays.  Patch from Thomas Holder.
458
459  + Fix KML export to avoid invalid geometry when a tube intersects itself.
460    Patch from Robert Jones.
461
462  + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
463    for now.  This is a workaround until wxWidgets OpenGL support is updated
464    to work under Wayland.  Reported by Philip Balister.
465
[0482978]466  + Fix warnings about using deprecated functions when building movie export
467    code using FFmpeg 4.0.
468
[3ed7da1]469* cavern:
[3147062]470
[3ed7da1]471  + Compass MAK files: Handle fixed point coordinates in feet - previously the
472    units were ignored and the coordinates assumed to be in metres.
[3147062]473
[3ed7da1]474  + Previously the first byte in a MAK file was ignored.  Typically MAK files
475    start with a comment, and since cavern currently ignores lines that start
476    with characters it doesn't understand the meaning of, this bug would often
477    go unnoticed.
[3147062]478
479* survexport:
480
481  + Fix exporting of passages, walls and cross-sections by running the code
482    aven uses to decide how much to rotate each cross-section.  Previously all
483    cross-sections were aligned West-East.  Reported by Robert Jones.
484
485  + Default to .pos output if the program name is 3dtopos, and install a second
486    copy (or hardlink under Unix) as 3dtopos.  This provides compatibility with
487    current releases of Tunnel.  Reported by Becka Lawson, Wookey and
488    Stephen Crabtree.
489
490* Fix some German translations.  Patch from Thomas Holder.
491
492* (MacOS X version): Fix aven-create-app to not delete converted icons.
493  Typo spotted by Robert Jones.
494
495* Improve documentation for *team.  Document the requirement to quote names
496  unless a person is identified by just one name.  Document that the roles are
497  optional, as that information may not have been recorded, and to align with
498  therion's team command.
499
[26ab0a7]500Changes in 1.2.36 (2018-07-18):
501
502* aven:
503
504  + Add support for exporting as a CSV (Comma-Separated Values) file.
505
506  + Support exporting KML with altitude mode "clamp to ground".  In this mode,
507    the altitude in the data is ignored and it's rendered on the surface of the
508    terrain.  This is useful if your KML viewer renders the terrain as opaque
509    so underground data isn't visible.  Rendering cave passages on the surface
510    isn't great, but is better than not being able to see them at all.  This
511    option may also be helpful if you want to see where to look on the surface
512    for new entrances.
513
514  + Highlight surveys with a white loop as the mouse is moved over them in
515    the survey tree.  This is akin to how we highlight a station with a
516    white ring, and allows restoring "double-click survey in tree to zoom"
517    which temporarily required a quadruple-click in 1.2.35.
518
519  + Only show checkboxes in the survey tree for surveys not stations.
520
521  + Fix wxWidgets assertion if the user tried to select additional surveys
522    to show via the right-click menu.
523
524  + Fix multiple survey filtering when both a parent and child survey are
525    selected.  In this case it makes most sense to show all child surveys of
526    the parent, but we actually showed a slightly arbitrary subset of the
527    child surveys of the parent.
528
529  + The checkbox area in the survey tree is now included in the area which
530    is considered by mouse-over updates such as highlighting the station or
531    survey.
532
533  + Fix display of double quotes in cavern log window (they were being replaced
534    with control character 0x16 due to a typo in the code).
535
536  + Add shortcuts to buttons in cavern log window.
537
538  + Eliminate use of gluErrorString() function which eliminates some
539    deprecation warnings when building on macOS.
540
541  + Reject multiple --survey command line options for now (only the last has
542    been used for a long time, but now we actually support multiple survey
543    filtering this matters more).
544
545* survexport:
546
547  + Report a useful error when trying to convert a .3d file without coordinate
548    system information to GPS.  Reported by Mark Shinwell.
549
550  + Handle multiple redundant --survey command line options correctly.
551
552* dump3d: Report station flag "WALL", which was added in 1.2.7.
553
554* Minor translation updates.
555
556* Update manual for Microsoft Windows changes.
557
558* tests/: Add test coverage for warnings about suspect readings
559
560* Fix warning when compiling with clang.
561
[facb636]562Changes in 1.2.35 (2018-07-03):
563
564* aven:
565
566  + Viewing can now be restricted to multiple surveys.  Use the right-button
567    menu on a survey in the survey tree and select "Show" to enable checkboxes
568    for that survey and all its siblings.  Only the selected surveys are shown
569    on screen, printed and exported.
570
571  + Don't open a survey when its name is double clicked.  This was happening
572    due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
573    However, reverting that change still seems to allow double-clicking to work
574    on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
575    survey.
576
577  + Pick initial survey scaling based on whichever of the window width or
578    height gives the smaller scale.  Previously we always used the window
579    width, which can result in parts of the cave being outside the initial
580    view.  Reported by Wookey.
581
582  + Drop ability to specify a PROJ string in the export dialog.  This was added
583    to allow exporting to formats such as GPX before we added support for
584    specifying the projection in .svx files, and that support is now mature.
585
586  + DXF export now uses 2 decimal places (was 6) for the bounding box, for
587    consistency with the precision used for coordinates.
588
589  + Fix handling of surface flag during export.  In formats which discriminate,
590    legs could previously have got assigned the wrong status.
591
592  + Fix bug which probably prevented aven starting when OpenGL double buffering
593    is unavailable.  This is unlikely to affect any common configurations.
594
595  + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
596    filenames.  Issue reported by Matic.
597
598  + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
599    Probably broken since 1.2.17.
600
601* survexport: New command-line export program which uses aven's export code.
602  Replaces 3dtopos, cad3d and findentrances, since it can do all that these
603  tools could do, plus much more.
604
605* Merge more Spanish i18n updates from Evaristo Quiroga.
606
607* Minor updates to various other translations.
608
609* img library:
610
611  + Now supports reading from and writing to an existing FILE*.
612
613  + Improve API documentation.
614
615* (Microsoft Windows version): Fix packaging to include wxWidgets translation
616  files like it was supposed to, which fixes a few missing translations.  This
617  was probably broken by changes in 1.2.8.  Reported by Evaristo Quiroga.
618
619* (Microsoft Windows version): Drop two options from explorer bindings.
620  "Convert to DXF" and "Convert for hand plotting" have both been supported via
621  aven for a while, and that's a more useful way to access them as you can
622  control what gets exported.
623
[5279c800]624Changes in 1.2.34 (2018-03-24):
625
626* aven:
627
628  + (Microsoft Windows version): Fix error on startup in the pre-built version
629    of 1.2.33.
630
631  + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
632
[f057bc1]633Changes in 1.2.33 (2018-03-22):
634
635* aven:
636
637  + Reliably disable scale bar in perspective view.  This is supposed to happen
638    (because the scale across the screen varies in perspective view) but
639    actually the scale bar stayed around until an update was forced for another
640    reason.  Spotted thanks to Pedro Silva Pinto.
641
642  + Make "no date"/"not in loop" colour grey.  The white was a bit bright and
643    made it harder to see the legs that had colours.  The grey now used is
644    within the brightness range of the other colours.  Fixes #94, reported by
645    Erin Lynch.
646
647  + Fix KML export - exporting both survey legs and station names resulted in a
648    malformed KML file.  This bug was introduced in 1.2.30 when support for
649    exporting passages and walls was added.  Reported by Erin Lynch in #90.
650
651  + Consistently use 2 decimal places for altitude in KML output.  Some places
652    used 8 decimal places which is appropriate for lat and long, but clearly
653    overkill for an altitude in metres and increases the file size
654    unnecessarily.
655
656  + Right-align bearing widget in print/export dialog.  The change to allow the
657    value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
658    left-aligned (due to incorrect wxWidgets documentation of the default style
659    for this control).
660
661  + (Unix version): Work around wxWidgets bug so that custom cursors work
662    under GTK3.
663
664  + (Unix version): Update GTK version reporting - report GTK3, and don't
665    bother to report subversions of GTK2 (it seems to be fairly arbitrary
666    which subversions wxWidgets defines constants for).
667
668  + Update code to work without warnings when using wxWidgets 3.1.0 (the
669    current development version).
670
671  + Make movie export code compatible with upcoming FFmpeg 3.5 release.
672    It should still work with the older versions that worked before this
673    change.  Reported by James Cowgill in https://bugs.debian.org/888334
674
675* cavern:
676
677  + Warn about 2 digit years.  We can't change the assumption that these are
678    19xx without risking breaking existing datasets, but the further we get
679    into this century, the more likely such an assumption is to catch someone
680    out.  The warning can easily be quashed by explicitly adding the assumed
681    "19".
682
683* The Spanish translation is now up to date once more, thanks to updates from
684  Evaristo Quiroga.
685
686* Merge French translation updates from Jean-Marc.
687
688* Fix transposed German Northing and Easting labels.  Fixes #95, reported by
689  milosch.
690
691* Fill in missing translations of "Easting", "Northing", "E" and "N" for
692  Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
693  translated messages.
694
695* Align .pos file headings better with columns of coordinates below for
696  Indonesian and Polish.
697
698* Fix handling of the message string "error" before messages loaded.  If
699  there's an error loading messages, we need this message to report it.
700  Reported by Martin Sluka.
701
702* Fix a few compiler warnings.
703
704* img library: Fix extracting leaf survey name for survey title.  When there
705  are three or more levels of survey, we were taking everything after the first
706  dot rather than everything after the last dot.
707
708* Fix problems with testsuite on macOS:
709
710  + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
711    - this test isn't meaningful unless the filing system is case-sensitive,
712    but happens to fail if it isn't.
713
714  + cavern.tst: Workaround limitations of Apple's sed.
715
716  + aven.tst: Fix not to hang on macOS.
717
718  + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
719
720* Clean up handling of support files in relocatable installs - this is now
721  detected at run time on macOS.
722
723* Split out macOS Aven.app creation into a make rule so it can be easily used
724  by the homebrew formula.
725
726* buildmacosx.sh:
727
728  + Fix when WX_CONFIG not specified - this was giving a confusing error like:
729    ./buildmacosx.sh: line 163: --cc: command not found
730
731  + Use wxWidgets 3.0.4.
732
733* Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
734  and we currently require 2.8 or newer.
735
[66576b6]736Changes in 1.2.32 (2017-07-08):
737
738* aven:
739
740  + Make splays on printouts a darker shade of grey.  Reported by Erin Lynch
741    and Anthony Day.
742
743  + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
744    POS), the value in the Z dimension was negated.  Bug introduced by fixes
745    for export of rotated plans and tilted elevations in 1.2.27.  Reported by
746    Erin Lynch in #89.
747
748  + Ignore viewing angles for export formats which work in 3D.  When the
749    rotation and tilt controls are hidden in the export dialog we were still
750    using their values to transform the data, so if you set them with for one
751    export format which support them, then switched to an export format which
752    doesn't, you'd get bogus coordinates in the exported file.  Bug probably
753    introduced in 1.2.27 by fixes for exports of rotated plans and tilted
754    elevations.
755
756  + Fix exporting to skencil and Survex .pos formats.  When aven's export to
757    .pos was added in 1.2.19, the ordering didn't match up and since then .pos
758    export has produced skencil files and vice versa.
759
760  + Don't leave terrain on if loading terrain data fails.  Previously if you
761    clicked the terrain icon (or via the menu) with no terrain loaded, but no
762    terrain got loaded (e.g. because the survey data lacks an explicit
763    coordinate system, or because the file failed to load, or because you
764    cancelled the dialog) then the terrain icon/menu item was still changed to
765    "on".
766
767  + Disable texturing while drawing terrain.  Previously the terrain got a bit
768    darker when "Textured Walls" were enabled.
769
770  + Force a refresh when "Textured Walls" are enabled or disabled.  Previously
771    the display wouldn't update right away.
772
773* Manual:
774
775  + Document how to specify fixed point altitude in feet.
776
777  + Explain why *fix warns about unused fixed points
778
779* Building from source now requires a compiler with decent support for C++11.
780  If you're using GCC, then GCC 4.7 should suffice.  This should not be an
781  onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
782  enough GCC.  If special options are needed, these should get probed for and
783  automatically.  Fixes building 1.2.31 with GCC < 6, reported by Wookey.
784
[28695f1]785Changes in 1.2.31 (2017-07-01):
[11c814b]786
787* aven:
788
789  + Use superscript 'g' symbol instead of word 'grads' in status bar.  This
790    conserves the limited space available, and we already do this in the
791    compass and clino indicators so it's more consistent too.
792
793  + Show one decimal place on measure line bearing.  Pointed out by Benedikt
794    Hallinger on the therion list, though I'm sure this has been asked for
795    before by others.
796
797  + Show gradient of the measuring line when both ends are stations.
798
799  + Allow selection of text in cavern log window.  Selection was disabled in
800    1.2.28 because it seemed you couldn't actually copy selected text to the
801    clipboard, but retesting this now actually works fine for me, both with
802    current git master with the change reverted, and with code just before the
803    original change.
804
[28695f1]805  + More robust parsing of cavern output (cleanly handle context highlighting
806    which extends beyond the end of the line).
[11c814b]807
808  + Allow showing duplicate legs as dashed lines or hiding them entirely,
809    with dashed now being the default.  Implemented by Patrick Warren.
810
811  + Also allow "Dashed" for splays and "Faded" for duplicate legs.
812
[28695f1]813  + Splay legs in surface data are also shown faded.
[11c814b]814
[28695f1]815  + Check environment variables VISUAL and EDITOR when looking for editor to
816    use when a warning or error is clicked on in the cavern log window.  The
817    specified editor may have a GUI or need to run in a terminal, so we have to
818    special-case each editor supported, and that means we can pass extra
819    options needed to position the cursor on the appropriate line/column.
820    Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
821    emacs, nano, jed, kate.  Suggested by Wookey.
[11c814b]822
823  + Fix handling of non-square terrain data files - the X and Y dimensions were
824    swapped.  Reported by detrito.
825
[28695f1]826  + Improve parsing of DEM data with .hdr file.  Use documented defaults for
827    more values, and where we only support a subset of values (or a particular
828    value) check for unsupported values in more cases.
829
830  + When colouring by depth, fix colouring and texturing of polygons which
831    cross depth bands.  The previous problems were most obvious with high
832    chambers and long legs down deep pitches, especially in for surveys without
833    much vertical range.
834
835  + Support for drawing blobs using point sprites was added in 1.2.28,
836    but caching that this worked wasn't hooked up properly so the test to
837    see if this worked would happen at the start of each run.  This is now
838    cached as intended which should reduce start up time a little when blobs
839    are drawn in this way.
840
841  + Fix drawing of crosses with lines.  This is a fall-back case which is
842    rarely used as most OpenGL setups will handle a better method, but it was
843    resulting in crosses with a four-pixel square in the centre - now the
844    centre should be a single pixel.
[11c814b]845
846* cavern:
847
[28695f1]848  + Allow *data with no arguments to reset the current style - useful for
849    entering passage data where there are side passages.
850
851  + Fix hang processing file without newline at end.  This bug was introduced
852    by changes in 1.2.28.  Reported by Mark Brown.
853
[11c814b]854  + (Mac OS X and Microsoft Windows versions): Build with newer version of
855    PROJ library which fixes buggy handling of *fix with lat-long coordinates.
[28695f1]856    Also add a testcase to the testsuite to alert users building for themselves
857    with an affected PROJ version on any platform.  Reported by Ross Davidson.
[11c814b]858
859  + Fix cavern to handle Compass .DAT with no survey team.  Previously this
860    resulted in the bogus error: Expecting numeric field, found "FROM"
861    Reported by Erin Lynch.
862
863  + Handle UTF-8 "BOM" at start of .svx files.  Unicode doesn't recommend its
864    use, but Microsoft stuff seems to like to create files with it in, and the
865    error cavern currently reports for such files is very confusing, so it
866    seems best to just handle it.  Reported by Rob Eavis.
867
868  + Change a couple of messages to use double quotes for consistency with all
869    other messages.
870
[28695f1]871* extend:
872
873  + Now runs a bit faster.
874
875  + Splays are now carried over the extended survey.  The current handling
876    is simplistic, but should do a good enough job to be more useful than
877    discarding splays.  The splays at each station are all rotated together
878    based on the bearing between the stations either side of the current one
879    along the first path extended through that station.  This nicely handles
880    dead ends and the situation at the top or bottom of a pitch, and should
881    tend to pick an angle close to the passage orientation along a traverse.
882    It's weakest at junctions.  Feedback (especially examples which could
883    be handled better) most welcome.
884
885* French translation is now up to date again, thanks to Jean-Marc.
886
887* Remove erroneous menu shortcut markers from Polish translations.
888
889* Fill in some missing translations in several languages by using message
890  translations from therion.
891
892* Add note to *fix documentation to clarify the coordinate order with *cs
893  long-lat.  Issue raised by Ross Davidson.
894
[11c814b]895* Fix errors in documentation of *units: "DEG" should be "DEGS", and
896  "MINUTES" has been supported for ages but wasn't documented.  Reported by
897  Footleg.
898
[28695f1]899* Fix a few typos in the documentation.
900
901* Fix compilation warning with recent GCC.
[11c814b]902
[56b37f3]903Changes in 1.2.30 (2016-10-03):
904
905* aven:
906
907  + (Microsoft Windows version): Fix crash when trying to print or export
908    (probably introduced in 1.2.28).  Reported by Brian Clipstone.
909
910  + Report error if terrain file contains no terrain data in area of survey.
911    Suggested by detrito.
912
913  + Errors when writing an export file were reported with the wrong filename
914    - the .3d file, not the filename we were trying to write to.
915
916  + Export to KML now supports exporting passages, walls and cross-sections.
917    Addresses the remainder of ticket #4.
918
919* Add man page for dump3d.
920
[d0418ac]921Changes in 1.2.29 (2016-09-27):
922
923* aven:
924
925  + Fix SVG output with non-ASCII characters (the charset in the SVG file
926    is now set to UTF-8 not ISO-8859-1).
927
928  + (Microsoft Windows version): Fix error dialog on startup in pre-built
[53c1e5d]929    version.  Reported by Brian Clipstone.
[d0418ac]930
931* Manual: Add link to TerrainData wiki page.  Omission highlighted by Erin
932  Lynch and "detrito".
933
934* Fix to build without FFmpeg/libav and with older versions, broken by changes
935  in 1.2.28.  Reported by James Begley.
936
[6897356]937Changes in 1.2.28 (2016-09-24):
[0d8f67a]938
939* cavern:
940
941  + Show the contents of the line after error and warning messages while
942    processing survey data, and indicate the region of the line in many cases
943    in the same style that compilers such as GCC and clang use (using the
944    column number we already have, plus new width information).  Based on a
945    patch from Mateusz Golicz.
946
947  + Add column and width information for many more error and warning messages.
948
949  + Fix column for "Separator in survey name" warning.
950
951  + Improve warnings when using a backclino with range 0-180 degrees (reusing
952    the same machinery we already have for a forward clino with range 0-180
953    degrees).
[99b3298]954
955* aven:
956
957  + Include LRUD in printout/export of extended elevations, broken by
958    improvements to export of tilted elevations in 1.2.27.  Reported by Anthony
959    Day.
960
961  + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
962    usefully.  Reported by Anthony Day.
963
964  + Remember scale from previous print or export operation in the same run of
965    aven.  Suggested by Stuart Bennett.
966
[0d8f67a]967  + Convert range indication below shown line to a highlight on that region
968    of the line in cavern log window.
969
[99b3298]970  + Fix colouring of error/warning without column in cavern log window.
971
972  + Fix click on error/warning without column in cavern log window.
973
[6897356]974  + Fix highlight of translations of "error" or "warning" containing non-ASCII
975    characters.  This fix for this only works with a Unicode build of
976    wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
977    shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
978    Reported by Mateusz Golicz.
979
[0d8f67a]980  + Disable selection of text in cavern log window - you can't currently copy
981    it to the clipboard, so until that's implemented it seems better to disable
982    the ability to select it.  Reported by Wookey.
983
[99b3298]984  + Avoid special "1000" scale entry when exporting.
985
986  + Show 1 page when "One Page" selected.
987
988  + Reload processed data when restricting view.  Fixes failure when
989    restricting view on data just processed via aven.  Spotted by Andrew
990    Atkinson and myself.
991
992  + Don't hide blobs and crosses behind terrain.  Reported by Jenny Black.
993
994  + Fix rendering of crosses using point sprites.  The texture being used was
995    misaligned relative to the image used for the visual fidelity check, so the
996    check always failed and point sprites would never be used.  Where point
997    sprites are supported, they're probably the fastest option - on my netbook
998    this change improves FPS by ~6 fold when displaying crosses for a large
999    survey.
1000
1001  + Support drawing blobs using point sprites.  About 5 times faster than using
1002    lines on my netbook.
1003
1004  + Recheck how best to draw crosses and blobs on the first run after Survex
1005    is upgraded (or downgraded) as the rendering code may have changed (we
1006    already recheck when the OpenGL hardware or driver changes).
1007
[6897356]1008  + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
1009    MPEG4 produces smaller output of higher quality, and should be widely
1010    supported these days.  And I can't get the MPEG1 output to work without
1011    buffer underflows, resulting in a file which doesn't play without
1012    glitches.
1013
1014  + Add OGG video to the list of formats - it's more compact than the others
1015    we currently list, though slower to write.
1016
1017  + Fix export to movie formats for which libav/FFmpeg needs to seek the file
1018    being written.  This was broken by changes in 1.2.27.
1019
1020  + Overhaul movie export for the current FFmpeg API, fixing deprecation
1021    warnings when building against a recent version.
1022
[99b3298]1023  + (Microsoft Windows version): Fix corrupted exported movie files.  1.2.27
1024    changed the movie export code to allow writing to files with non-ASCII
1025    characters in the names, but the new code failed to open the file in binary
1026    mode, leading to corrupt output.  Fixes #81, reported by Erin Lynch.
1027
[f55cbeb]1028  * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
1029    movie export.
1030
1031  * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
1032    export.
1033
[99b3298]1034* Fix to build without FFmpeg/libav, broken by changes in 1.2.27.  Reported by
1035  James Begley.
1036
[0d8f67a]1037* The Polish translation is now very close to being complete, thanks to a
1038  substantial update from Mateusz Golicz.
1039
[99b3298]1040* Merge catalan translation updates from Adolfo Jayme.
1041
[7333c2c]1042* (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
1043  messages get used automatically.
1044
1045* cavern.tst: Remove random : from after ] - dash ignores the extra character,
1046  but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
1047
[0d8f67a]1048* cavern.tst: Add expected output for more testcases.
1049
1050* Remove unwanted execute bit from some testcase data.
1051
1052* Use https for more URLs which support it.
1053
[690fdab]1054Changes in 1.2.27 (2016-06-06):
[dfe8d05]1055
1056* aven:
1057
1058  + Right click on a survey in the survey tree now gives a pop-up menu
1059    with "Hide others", which restricts the view to just that survey
1060    and any subsurveys.  Right click on the root of the survey tree
1061    gives a menu with "Show all" to undo any restriction in effect.
1062    (Currently these are implemented by reloading the file and using
1063    the same machinery as the --survey= command line option, but that will
1064    probably change in the future).
1065
[690fdab]1066  + If there's a sub-survey restriction (from the --survey= command line
1067    option or the new UI described above) it is now shown in brackets after
1068    the survey tree root.
[dfe8d05]1069
[690fdab]1070  + When reloading a survey, preserve the current view position (previously
1071    the view was recentred).
[dfe8d05]1072
1073  + When reloading a survey, actually preserve the current scale factor
1074    (this was meant to happen, but the adjustment was applied in the
1075    wrong direction).
1076
1077  + New "File->Extended Elevation..." menu item provides a way to generate
1078    extended elevations for simple cases without having to use the command
1079    line.  Suggested by Fleur Loveridge.
1080
[690fdab]1081  + Don't process key presses if accompanied by an unexpected modifier key.
1082    In particular, this means that aven no longer interferes with Alt+<function
1083    key> (which is typically handled by the desktop) and Alt+<letter> (which is
1084    typically a menu short cut).  Reported by Владимир Георгиев.
[dfe8d05]1085
1086  + Reduce file loading time by ~5%.  The station name compare function was
1087    something of a hot spot, and optimising it yielded a nice improvement.
1088
[690fdab]1089  + Allow splay legs to be disabled in when printing and exporting.  Mostly
1090    addresses #60.
1091
1092  + SVG export now shows splay legs thinner and in grey.  See #60.
1093
1094  + Fix export of rotated plans and tilted elevations - previously plans were
1095    always aligned with North up, and elevations which weren't exactly side on
1096    were exported as plans.  Reported by Stuart Bennett.
1097
1098  + Fix offset bounding box for exported elevations.
1099
1100  + In print/export dialog the bearing value now wraps if you scroll up past
1101    360 or down past 0.
1102
1103  + Fix greying out of LRUD-based controls in the print/export dialog when the
1104    view is tilted (i.e. not plan or elevation).  This stopped working in
1105    1.2.18 when the pan and tilt spin controls were changed from integer- to
1106    real-valued ones.
[dfe8d05]1107
1108  + Printouts now show LRUD as pale grey arrows from the station they are
1109    measured from.  Based on patch from Michael Sargent.  Closes #65.
1110
[690fdab]1111  + Take LRUD into account for printout size.  Fixes #72, reported by Erin
1112    Lynch.
[dfe8d05]1113
[690fdab]1114  + Update movie export code to work with latest version of FFmpeg.
1115
1116  + Make "Show Log" a toggle, so you can click on the button to take a look at
1117    the log, and a second click returns you to the survey view.
1118
1119  + (Microsoft Windows version): Open the font file in binary mode - it looks
1120    like we were lucky and the font file (or at least its current version)
1121    would have loaded OK in text mode despite being binary data.
1122
1123  + (Microsoft Windows version): Exporting to files with non-ASCII filenames
1124    should now work.
[dfe8d05]1125
1126* cavern:
1127
1128  + Allow tape or backtape to be omitted.  Reported by Erin Lynch.
1129
1130  + Grid convergence is now corrected for when using automatically
1131    calculated declinations (*declination auto <X> <Y> <Z>).  Requested
1132    by Mateusz Golicz on the mailing list.
1133
1134  + Clear any cached calculated declination upon another *declination auto
1135    with different coordinates.  Previously if the date stayed the same,
1136    a previously cached declination for the old coordinates was used.
1137
1138  + Fix check for end of version number array in *required.   We would check up
1139    to 12 version components, the last 9 being bogus.  In practice, *require is
1140    only likely to be used with up to three components, so this wouldn't be an
1141    issue.
1142
1143  + *begin with an invalid prefix could cause a crash in some cases.  Fixed
1144    by patch from Colin Watson.
1145
[690fdab]1146  + Report column locations for errors to do with readings.
1147
[dfe8d05]1148* Merge translation updates from Jean-Marc.
1149
1150* img library: Better document which members can be set when writing.
1151  Highlighted by email query about use of img API from Владимир Георгиев.
1152
[690fdab]1153* Document how *declination interacts with *calibrate declination if both are
1154  used in the same dataset.
1155
[dfe8d05]1156* doc/3dformat.htm: Update details of how changes to the current label buffer
1157  are encoded to reflect changes in v8.  Reported by Angus Sawyer.
1158
1159* Use docbook2man instead of docbook-to-man to generated Unix man pages
1160  from SGML source.  The latter seems to be no longer actively maintained, and
1161  docbook2man now does a similarly good job.
1162
1163* Use https for survex.com links, and for other sites which support it.
1164
[cd746b9]1165Changes in 1.2.26 (2016-01-07):
1166
1167* aven:
1168
1169  + (Microsoft Windows version): Fix to be able to process .svx files with
1170    cavern again.
1171
[8ee50db]1172* (Microsoft Windows version): Simplify upgrading process with innosetup
1173  installer - if Survex is already installed, we now just install to the same
1174  location and use the same start menu folder.
1175
1176* (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
1177  Fixes #79, reported by James Begley.
1178
1179* (Linux version): survex.spec: Fix to work with RPM 4.13.  Fixes #79, reported
1180  by James Begley.
1181
[cd5cd8f]1182Changes in 1.2.25 (2016-01-05):
[4e92bec]1183
[cd5cd8f]1184* aven:
[4e92bec]1185
[cd5cd8f]1186  + Drop broken code which attempts to fix 2D pitches.  Fixes #73, reported by
1187    Erin Lynch.  #76 tracks the issue the removed code was trying (but failing)
1188    to address.
[4e92bec]1189
[cd5cd8f]1190  + When animating, don't try to update station info based on mouse movement
1191    over the survey tree.
[4e92bec]1192
[cd5cd8f]1193  + Further improve code to handle cavern subprocess in aven.
[4e92bec]1194
[cd5cd8f]1195  + Fix jump to error for filenames containing colons when the error location
1196    doesn't have a column number.  Bug noted by Jenny Black.
[4e92bec]1197
[cd5cd8f]1198  + If we encounter bad UTF-8 in cavern output, replace it with a red and white
1199    ? in a diamond (previously we gave up showing output at the first bad
1200    sequence).  This can happen if you process a .svx file which isn't UTF-8
1201    encoded.
[4e92bec]1202
[cd5cd8f]1203  + (Unix version): Don't try to set the terminal window title when opening an
1204    editor from the cavern log window - gnome-terminal no longer supports this,
1205    and there doesn't seem to be a portable option for specifying the title for
1206    terminals which do still support this.
[4e92bec]1207
[cd5cd8f]1208  + (Microsoft Windows version): Also quote for cmd.exe so that paths with
1209    spaces in work reliably.  Reported by Marco Cotto.
[4e92bec]1210
[cd5cd8f]1211* cavern:
[4e92bec]1212
[cd5cd8f]1213  + Improve error for mismatched fore/back-sight plumbs, reported by Andy
1214    Edwards (see #78).
[4e92bec]1215
[cd5cd8f]1216  + Fix to use correct sd for backcompass.  We were using zero instead, the
1217    most obvious effect of which was that the threshold for warning about
1218    differing COMPASS and BACKCOMPASS was about 71% of what it should have
1219    been, so we were warning in more cases than we should have been.
[4e92bec]1220
[cd5cd8f]1221  + Implement support for specifying a length on backsights - if you're using
1222    something like a disto-x, you'll get a distance reading for the backsight
1223    too.  Fixes #71, reported by Erin Lynch.
[4e92bec]1224
[cd5cd8f]1225  + Make line counting more robust to mixed line ends.  Noticed in example file
1226    from Pete Smart (see #69).
[4e92bec]1227
[cd5cd8f]1228* extend: New --show-breaks option which adds a leg flagged as surface survey
1229  between each points at which a loop has been broken.  Suggested by Jenny
1230  Black.
[4e92bec]1231
[cd5cd8f]1232* (Unix version): Update filetype metadata to work with modern desktops.
[4e92bec]1233
[cd5cd8f]1234* Fix incorrect reporting of errors reading and writing processed survey data.
1235  Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
1236  IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
1237  external programs using the img library, only Survex).  Reported by Jenny
1238  Black.
[4e92bec]1239
[cd5cd8f]1240* Add missing options to extend man page and --help output.  Noted by Jenny
1241  Black.
[4e92bec]1242
[cd5cd8f]1243* Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
[4e92bec]1244
[cd5cd8f]1245* Fix broken SGML markup in manual.
[4e92bec]1246
[cd5cd8f]1247* Fix typo in manual reported by Jenny Black.
[4e92bec]1248
[cd5cd8f]1249* Update vim syntax file for newer commands, etc.
[4e92bec]1250
[cd5cd8f]1251* Minor translation updates.  Thanks to Piotr Strębski and Jean-Marc.
[4e92bec]1252
[cd5cd8f]1253* Fix to compile with FFmpeg 2.9.  Reported by Andreas Cadhalpun in
1254  https://bugs.debian.org/803863
[4e92bec]1255
[cd5cd8f]1256* Stop maintaining ChangeLog files.  They make merging patches harder, and stop
1257  'git cherry-pick' from working as it should.  The git repo history should be
1258  sufficient for complying with GPLv2 2(a).
[4e92bec]1259
[cd5cd8f]1260* (Microsoft Windows version): The installer requires admin privileges on Vista
1261  and later and OS versions older than Vista are past end of life, so drop code
1262  which tries to set up the registry differently depending if we have admin
1263  privileges or not.
[4e92bec]1264
[52dad0e]1265Changes in 1.2.24 (2015-09-23):
1266
1267* aven:
1268
1269  + (Microsoft Windows version): Fix the cavern log window.  Reported by Brian
1270    Clipstone.
1271
1272  + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
1273    Reported by Jenny Black.
1274
1275  + If wx was built with thread support, aven now runs cavern from a separate
1276    thread, which works much better under wxMSW (where we can't use select),
1277    and also seems a bit smoother on Linux.
1278
1279  + Fix handling of encoding of filenames when the operating system has no
1280    locale installed corresponding to the language selected for Survex's
1281    messages.
1282
1283  + Undo accidentally committed debugging code which was sending message to
1284    the terminal in 1.2.23.
1285
1286* (Linux version): configure now looks first for wx-config-3.0, which Fedora's
1287  wx3 packages have.  Reported by James Begley.
1288
1289* Indonesian translation fully up to date again.
1290
1291* Manual: Document anonymous stations, based on the text from NEWS.  Reported
1292  by Wookey.
1293
[1ff33eb]1294Changes in 1.2.23 (2015-09-06):
[1ed104f]1295
1296* aven:
1297
1298  + Updating the cavern log window is now much smoother, especially on slower
1299    machines.
1300
1301  + Show "busy" mouse cursor while processing survey data.
1302
1303  + Fix an assertion if you try to start processing a survex file while one is
1304    already being processed.
1305
1306  + Processing a .svx file with an error now still adds it to the file history.
1307    Reported by Martin Green.
1308
[d56a2d4]1309  + Fix the orientation of the starting end of tubes.
1310
1311* cavern:
1312
1313  + New *ref command to allow specifying an external reference (e.g. where to
1314    find the original survey notes).
1315
1316  + Drop support for showing percentage progress in cavern.  It's confusing in
1317    a multiple-file dataset as it shows progress in the current file so jumps
1318    around.  It also slows down processing, and on a slow machine you'd don't
1319    want that, while on a fast machine processing isn't slow enough for the
1320    progress display to be useful.
[1ed104f]1321
1322* French translation is now completely up to date, thanks to Michel Bovey.
1323
[d56a2d4]1324* Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
1325  OS X so that things like "*cs EPSG:29903" work.  Reported by Graham Mullan.
1326
[1ed104f]1327* (Microsoft Windows version): Process survey data with aven rather than
1328  running cavern.
1329
[53b6a5a]1330* (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
1331  releases have been built with 5.5.3) to see if that solves Ray Duffy's
1332  reported issue with not having file associations for .svx files created.
1333
[7f7dbd5]1334Changes in 1.2.22 (2015-08-17):
[d225571]1335
1336* aven:
1337
1338  + Ensure that the window has a depth buffer.  Whether it does by default
1339    seems to vary depending on OS and maybe graphics card.  Fixes #55 (terrain
1340    is no longer visible through itself), and also the rendering of passage
1341    tubes.  Thanks to Martin Green for pointing me in the right direction for
1342    finding this fix.
1343
1344* cavern:
1345
1346  + Fix *declination with an angle to actually work.
1347
1348  + Fix assertion if we try to identify a hanging survey by an anonymous
1349    station.
1350
[7f7dbd5]1351  + Improve errors for invalid survey names in *begin, *end, *equate and
1352    *export.
1353
[2d865b7]1354Changes in 1.2.21 (2015-07-28):
[31e9b72]1355
[03c259e]1356* aven:
1357
[2d865b7]1358  + Fix exporting to KML and other text-based formats to always use "." for the
1359    decimal separator - previously "," would be used when the user's locale
1360    specified this for the decimal separator.  Reported by Jan Schorn.
1361
[22f17f1]1362  + Implement exporting of survey legs in KML format.
1363
[03c259e]1364  + Put "paddle" placemarker icons on stations in exported KML files, using the
1365    same colour coding for entrances, fixed points and exported points as aven
1366    does.
1367
[2d865b7]1368  + Remove the "Coordinate projection" field from the print dialog, as it isn't
1369    relevant there.  Reported by Wookey.
1370
1371  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1372    been too small).  Reported by Wookey.
1373
1374  + Don't rescale if the same file is reloaded, but adjust the volume diameter
1375    as appropriate.
1376
[03c259e]1377  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1378    values on Windows.
1379
1380* cavern:
1381
[22f17f1]1382  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1383    radians, but we were passing degrees, which would generally cause the
1384    conversion to the output coordinate system to fail.  Reported by Wookey.
1385
[2d865b7]1386  + Fix *fix with standard deviations when *cs is in use, give an error for use
1387    of *fix with standard deviations before *cs.
1388
1389  + Add new *declination command with support for setting the declination
1390    automatically from the IGRF model based on the survey date.  Thanks to the
1391    Therion developers for the IGRF support code, which we're reusing.
[1687a13]1392    Fixes #54, reported by Wookey.
1393
1394  + Allow the units for the zero error to be specified, making it easier to
1395    specify calibration with a scale if you measure the zero error externally
1396    (rather than using the instrument itself).  Fixes #61, reported by Andrew
1397    Atkinson.
[2d865b7]1398
1399  + Report the error from PROJ when coordinate conversion fails as part of the
1400    actual error rather than on a separate line.
[22f17f1]1401
[03c259e]1402  + Fix use after free after *solve.  This only occurs if a leg between the two
1403    exact same stations appears right before and right after the *solve, which
1404    is unlikely in real data, but the testsuite has an instance of this.  This
1405    was introduced by the repeat leg averaging added in 1.2.17.
1406
1407  + Fix small memory leak when solving network.  This doesn't really matter
1408    when solving at the end of processing as cavern will exit after that, but
1409    if *solve is used we continue processing after solving.
1410
1411* Remove compatibility handling for specifying a country variant of a language
1412  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1413  changed to the standard "en_US" way back in 2001.  This code was mangling
1414  character sets with a "-" in, and is no longer useful.
1415
1416* Ignore any "@<something>" modifier in the language code.
1417
[2d865b7]1418* Improve documentation of magnetic declination handling, and cover the new
1419  "*DECLINATION" command.
1420
[ab3b4a9]1421* Document aven's command line options in the manual and its man page.
1422  Reported by Jenny Black.
1423
1424* Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1425  documentation.
1426
[22f17f1]1427* Remove references to SpeleoGen from the documentation - it hasn't been
1428  updated for many years, and can't read recent versions of the .3d format.
1429
1430* Strip documentation references to obsolete versions of MS Windows.
1431
[2d865b7]1432* doc/HACKING.htm: Update list of debian packages to install to build from git.
1433
[7027ea1]1434Changes in 1.2.20 (2015-06-26):
[0eaf4b1]1435
1436* aven:
1437
[6de8e942]1438  + When printing, use the top margin rather than the right margin to calculate
[31e9b72]1439    the height of the printable area.  In practice, the two values seem to be
1440    the same or very similar by default.
[0eaf4b1]1441
1442  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
1443    Maynard.
1444
1445  + Optimise the size of the about dialog images.
1446
[7027ea1]1447  + Add support for reading terrain data which isn't in a .zip file.
1448
1449  + Force a refresh after loading terrain data so that it gets displayed right
1450    away.
1451
1452  + Make checks for terrain data extensions in zip files case insensitive.
[6de8e942]1453
1454  + If reading terrain data fails, always report an error and never try to
1455    display it.
1456
1457* cavern: Allow clino readings in diving style data, suggested by Andrew
1458  Atkinson.  Currently these readings are ignored, but a future version will
1459  check that they're consistent with the angle given by the depth gauge and
1460  tape, and perform suitable averaging.
1461
[0eaf4b1]1462* Remove lingering traces of svxedit.
1463
1464* configure: Fix to allow compiling without libav/ffmpeg, as was possible
1465  before 1.2.19.
1466
1467* (Unix version): Install the filetype and aven application icons under
1468  /usr/share/icons/hicolor, which is where they're expected to be these days.
1469
1470* (Unix version): Add %f to Exec in survex-aven.desktop.
1471
1472* (Mac OS X version): Remove useless extra copy of about box images from OS X
1473  disk image.
1474
[6de8e942]1475* (Mac OS X version): Only ship one copy of each of the translations.
1476
[0eaf4b1]1477* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1478  libav features we don't use.
1479
1480* (Microsoft Windows version): Reduce the size of the aven binary by disabling
1481  a load of libav features we don't use.
1482
1483* (Microsoft Windows version): Update message files to fix a missing Chinese
1484  message in the installer.
1485
[1dc99d1]1486Changes in 1.2.19 (2015-06-18):
[f96ac93]1487
1488* aven:
1489
1490  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1491    the exported file in 1.2.18.
1492
[2dac61e1]1493  + Add exporting to Survex .pos format.
1494
[4b67f71]1495  + If the measuring line isn't currently active, pressing "Escape" will now
1496    exit full screen mode.
1497
1498  + (Mac OS X version): Change the shortcut for full screen mode to be the
1499    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1500    using since 1.2.7).
[2dac61e1]1501
[f96ac93]1502  + (Mac OS X version): When we centre the view on the station this can
1503    generate a mouse move event, so clear the variable which says we are
1504    dragging before we process a left click on a station.  This avoids random
1505    rotations of the survey when clicking on a station, reported in #47 by Hugh
[2dac61e1]1506    St. Lawrence.
[f96ac93]1507
1508  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1509    icons from being rescaled and looking fuzzy.
1510
1511  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1512    toolbar icons from being rescaled, but which requires an unreleased version
1513    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1514
1515  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1516    the top of the screen, since we can't seem to display the menu bar in this
1517    case like we do on other platforms.
1518
[739440f]1519  + (Mac OS X version): Enable aven's movie export feature.
1520
[2dac61e1]1521  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1522    support multi-monitor setups.
1523
[f96ac93]1524  + (Mac OS X version): Silence warning visible when aven is run from a
1525    terminal about a missing CFBundleTypeRole.
1526
[4b67f71]1527  + When reading terrain data from a .zip file, report an error if the .zip
1528    file is bad, or if it doesn't contain any terrain data we recognise.
1529
[f96ac93]1530  + Tweak error message in terrain reading code to distinguish two failure
1531    cases.
1532
[2dac61e1]1533  + Add viewing angles and scale to footer, and shorten some of the other items
1534    to make room for this extra information.  (Fixes ticket #52, reported by
1535    Erin Lynch)
1536
1537  + If the footer is wider than the printout width, scale down the font used
1538    so that it exactly fits; if the footer is narrower, than space out the
1539    items in in so it uses the full width.
[f96ac93]1540
1541  + If the saved size for aven's window exceeds the current display size
1542    (mostly likely because we're now plugged into a smaller monitor), then
1543    reduce the size of the window to fit the display.  If the saved size is <
1544    (480x320), increase it to at least that, as aven isn't usable in a smaller
1545    window.
1546
[2dac61e1]1547  + Remove crude bodge which tries to pick a nicer initial window size when
1548    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1549    with the same size window it had when it was closed, so the initial size is
1550    only relevant on the first ever run.
[f96ac93]1551
1552* Assorted translation updates.  Notably Indonesian is at 100% again.
1553
1554* Stop trying to catch and report signals.  The only real reason to do it is so
1555  we can say "Bug in program detected! Please report this to the authors"
1556  before we exit, but when the program crashes that's pretty obvious.  In aven
1557  we try to pop up a message box for this message, which may fail due to
1558  whatever caused the signal, while with the command line tools there's no
1559  great benefit over just letting the shell report the signal.
1560
[4b67f71]1561* Use pkg-config to probe for libav and proj, which sorts out the correct flags
1562  for building on OS X against a static install of libav.
1563
[3f02aa4]1564Changes in 1.2.18 (2015-06-03):
[2595419]1565
[4a8031f]1566* aven:
[a5670c7]1567
[4a8031f]1568  + Add support for reading terrain data (from a zip file containing either an
1569    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1570    rendering it as a transparent surface.
[a5670c7]1571
[4a8031f]1572  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1573    sanely want to perform from the menu.
[a5670c7]1574
[4a8031f]1575  + Create a "Colour by" submenu of the "View" menu to house the various
1576    colouring options.
[a5670c7]1577
[4a8031f]1578  + Add "Colour by Gradient" and "Colour by Length".
[a5670c7]1579
[4a8031f]1580  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1581    which seems more logical, and also allows the dialog to be closed by
1582    pressing "Escape".
[a5670c7]1583
[38e5701]1584  + Destroy any existing clipping region before we write the page footer.
1585    Hopefully solves ticket #52, reported by Erin Lynch.
1586
[4a8031f]1587  + Don't round bearing and tilt angles to integers when printing and
1588    exporting.
[a5670c7]1589
[38e5701]1590  + Add passage export for EPS format.  (Partly addresses ticket #4)
1591
1592  + Add JSON export.  This should be regarded as experimental, and the format
1593    is quite likely to change.
1594
[4a8031f]1595  + Pressing F6 now toggles the display of rendering stats, currently FPS
1596    (Frames Per Second) and the number of triangles in the terrain mesh.
[a5670c7]1597
[4a8031f]1598  + Add a menu item and toolbar button to show the cavern log window if the
1599    currently shown survey data was processed by aven.  Reported by Hugh St
1600    Lawrence in #47, and by Dave Clucas and others previously on the list.
1601
1602  + Add "Save Log" button to Aven's cavern log window.
1603
1604  + In cavern log window, highlight "error" markers in red and "warning"
1605    markers in orange.
1606
1607  + Rework code to read cavern's output.  In particular, we no longer mix
1608    buffered and non-buffered system calls.
1609
1610  + Aven's support for reading colours and font sizes for printouts from
1611    print.ini has never worked - the contents of the ini files are ignored due
1612    to a bug which has been there since the code was added in 2005 - but nobody
1613    has ever complained.  So just strip out that code entirely - we should
1614    support setting the colours and font sizes, but a GUI interface for setting
1615    them would be better.
1616
1617  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
1618    Gee.
1619
1620  + Take the width of the messages used above the compass and clino into
1621    account when calculating how much space to allow for them - now the labels
1622    won't overlap or be cut off in translations where they are long.
1623
1624  + (Mac OS X version): Attempt to address the size of the toolbar icons.
1625
1626* cavern:
[0476b10]1627
[38e5701]1628  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
1629    susscorfa).
1630
[4a8031f]1631  + Use the currently set units when outputting measurements in warnings,
[38e5701]1632    errors, and the stats at the end of the run.  Requested by Bill Gee.
[4a8031f]1633
1634  + Include column number when a *include file isn't found.
1635
1636  + Show 'error' in front of error messages, like we show 'warning' in front of
1637    warnings.  Fixes #48, reported by Wookey.
1638
1639  + Increase the threshold for warning that fore and back measurements differ
1640    from 2 SDs to 3 SDs.
1641
1642* findentrances: If the 3d file specifies the coordinate system, use it.
1643
1644* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1645  would be nice to have, svxedit doesn't really offer that, and it looks ugly
1646  in a modern desktop.
[a5670c7]1647
[dd65182]1648* If we run out of memory while reading a processed survey data file, include
1649  the filename in the error message.
1650
[4a8031f]1651* Many translation updates - notably Indonesian and Russian are now the two
1652  most complete translations.
[dd65182]1653
[4a8031f]1654* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
[dd65182]1655
[4a8031f]1656* Transliterate gradient and infinity symbols if the current character set
1657  lacks them.
[dd65182]1658
[4a8031f]1659* Add SVG version of .plt icon.
1660
1661* Manual:
1662
1663  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
1664    highlighting that the previous list was incomplete.
1665
1666  + Document averaging of a group of repeated readings.
[dd65182]1667
[4a8031f]1668  + Add a link to the sample data from the manual.
[dd65182]1669
[4a8031f]1670  + Remove references to contact addresses which are no longer there.  Remove
1671    offer to post people floppies, and references to a CD image which isn't
1672    available for download.
1673
1674* Remove non-breaking spaces from the diffpos and extend manual pages, as they
1675  actually make the output formatting worse (presumably these used to work
1676  around a since-fixed bug in one of the docbook processing tools).
[2595419]1677
[4a8031f]1678* doc/TODO.htm: Update.
[dd65182]1679
[3f02aa4]1680* Fix to compile without warnings with 'g++ --std=gnu++11'.
1681
[1646310]1682Changes in 1.2.17 (2015-02-24):
[a6064e2]1683
1684* MacOS X version:
1685
1686  + Update INSTALL file with current status.
1687
[e067870]1688  + Aven.app now has a custom icon.
[9e053fc]1689
[e067870]1690  + Add icons for all the filetypes supported.
1691
1692  + Add Finder actions for .svx, .3d, .plt and .pos files.
[9e053fc]1693
1694  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1695    currently do this for us.
1696
[a6064e2]1697  + aven: Fix short-cut for toggling Full Screen mode.
1698
1699  + aven: Make "About" menu item appear.
1700
[9e053fc]1701  + aven: Fix "Close" button in about dialog.
1702
1703  + aven: Make custom cursors black with a white outline to match the standard
1704    OS X cursor.
1705
[e067870]1706  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
1707    still doesn't really work like a standard app though - e.g. you can't load
1708    files from Finder (instead run svxedit.app and use File->Open), the font
1709    size of most menu items is wrong, the icon for the app is the wish icon
1710    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1711    probably more.  I'd probably recommend using another editor (OS X comes
1712    with TextEdit.app for example).
1713
1714  + The documentation is now in a "Docs" directory alongside the apps, rather
1715    than in the rather less obvious "share/doc/survex" directory.
1716
[a6064e2]1717  + Default to building for x86_64, since all modern Macs are 64 bit.
1718
[9e053fc]1719  + Disable use of liblzma when building wxWidgets for OS X, which was
1720    preventing the build from working on OS X 10.6.8.
1721
1722  + Download wx sources from SF via redirecting link.  Thanks to David A.
1723    Riggs.
1724
1725  + buildmacosx.sh: Handle the mount point for the disk image containing a
1726    space.
1727
[4baea3a]1728  + Link with a static build of PROJ for doing coordinate system conversions.
[9e053fc]1729
1730  + Build wx with --disable-webview to avoid a compilation failure on OS X
1731    10.10.1.
1732
1733  + Use wx-config --cc and --cxx to get the compilers to use for building
1734    everything else, as wx adds options to them which otherwise cause linking
1735    errors.
1736
[4baea3a]1737  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
1738    smaller download.  This means OS X 10.4 is required, but we probably
1739    already need at least 10.5 because that's the minimum version which the
1740    wxWidgets build supports by default.
1741
[e067870]1742  + Remove unused files and copies of files from the diskimage.
1743
[a6064e2]1744* cavern: If the same leg is repeated consecutively, average the readings and
1745  treat as a single leg.
1746
[9e053fc]1747* dump3d: Report SEPARATOR used by the file being read.
1748
1749* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
1750
1751* aven:
1752
1753  + Greatly reduce flicker when mouse is moved to the top of the screen in full
1754    screen mode and the menu bar reappears.
1755
1756  + For export formats where scaling is supporting, aven now actually uses the
1757    scale specified in the export dialog (previously it ignored this and used
1758    1:500).
1759
1760  + Reimplement animation so that it's based on angular change per unit of
1761    elapsed time, rather than averaging the time take for the last two scene
1762    redraws.  This gives smoother animation in the face of variable load and
1763    scene redraw time, and should be more consistent between platforms.
1764
1765  + Switching to a point of the compass during auto-rotation now jumps straight
1766    there rather than the two animations fighting.
1767
1768  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
1769    fast.
1770
1771  + Disable stepping the rotation angle when animating (previously we only did
1772    when rotating).
1773
[1646310]1774  + Speed up start-up a bit - rather than loading icons from individual PNG
1775    files on disk, compile them into the aven binary.
1776
1777* (Unix version): Add "MimeType" field to desktop files so that file
1778  associations work out of the box with modern desktop environments.
1779
1780* Add start of Hungarian translation from Imre Balogh.
1781
1782* Merge in many updates to the Russian translation from "vsuhachev".
1783
1784* Assorted minor updates to other translations.
1785
1786* Create scalable (SVG) versions of file type icons.
[e067870]1787
[a6064e2]1788* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
1789  we're using git.
1790
[1646310]1791* tests/: Improve test coverage in a few places:
1792
1793  + Extend tests of fore and back sights to test calibration of the back
1794    compass.
1795
1796  + Test "Can't calibrate angular and length quantities together" error.
1797
1798  + Check that "*set names ." works when "." is also the decimal point.
[a6064e2]1799
[03d0e8b]1800Changes in 1.2.16 (2014-10-17):
[9aa10ad]1801
1802* aven: Add KML export (stations only currently).
1803
[f480117d]1804* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
1805
[9aa10ad]1806* aven: Fix corrupted names in exported files.
1807
1808* aven: Fix error log window under wxWidgets >= 2.9 to include the system
1809  information before the first log message like it does under wxWidgets 2.8.
1810
1811* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
1812
1813* tests/: Improve test coverage.
1814
[7bd113b]1815* Translation updates for many languages, plus the start of translations to
1816  Greek and Polish.
[9aa10ad]1817
1818* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
1819  by Martin Sluka.
1820
1821* Fix warnings when compiling with clang (which is the default compiler on
1822  Mac OS X).  Reported by Martin Sluka.
1823
[44f51ca]1824Changes in 1.2.15 (2014-08-14):
1825
1826* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
1827  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
1828  means that we now support all the coordinates systems which Therion does,
1829  except for a few which don't have X=East and Y=North.  The documentation
1830  for *cs has also been improved.
1831
1832* aven: We no longer persist full screen mode between runs - it's not a
1833  standard behaviour of desktop programs, and it's too easy to go into full
1834  screen mode from the menu and then not be able to get out again because you
1835  don't know the required key shortcut. (ticket#39)
1836
1837* aven: When in full screen mode, moving the mouse to the top of the screen now
1838  makes the menu bar appear.  This provides a non-shortcut way out of full
1839  screen mode, as well as making it easier to perform other operations while in
1840  full screen mode.  The current implementation gives an annoyingly flickery
1841  transition, but hopefully we can improve this in future. (ticket#39)
1842
1843* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
1844  development), we now call EnableFullScreenView() which improves the full
1845  screen mode experience on OS X 10.7 and later.
1846
1847* img library: Improve documentation for img_ERROR_INFO.
1848
1849* tests/: Ship some missing .out files and compare.tst.
1850
1851* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
1852  testcase, and extend it to cover a variant of the situation reported as a bug
1853  in therion by Bill Gee to the therion list.
1854
1855* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
1856  for the survex package and on tk for the svxedit package.
1857
[6a87cce]1858Changes in 1.2.14 (2014-07-05):
[5c676e2]1859
[1efeb6d]1860* img library: Add ability to store a PROJ4 string describing the coordinate
1861  system in use in 3d v8 files.
1862
1863* aven: If the 3d file specifies a coordinate system, then use it for exporting
1864  to formats which need to know (currently GPX).  If the input file doesn't
[6a87cce]1865  specify the coordinate system, allow the user to enter a PROJ4 string in the
1866  export dialog.
[1efeb6d]1867
[ea59b58]1868* aven: You can now quickly zoom to a particular area by holding down the
1869  "Shift" key and dragging with the left mouse button to create a rectangular
1870  "rubber band box" around the area you wish to zoom to.  If you release the
1871  "Shift" key while still dragging, the box is centred on the start point
1872  rather than having one corner there.
1873
[26e7fa4]1874* aven: Fix exporting of passage tubes in elevations and extended elevations
1875  - previously up and down were getting drawn across the page!
1876
[5c676e2]1877* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1878  1.2.13.  (Reported by Brian Clipstone)
1879
[515b83e]1880* aven: Fix the conditions on which the menu item "Cancel measuring line" is
1881  enabled - previously it was hard to actually cancel it via the menu.
1882  Reported by Hugh St Lawrence.
1883
[5c676e2]1884* aven: Fix wx assertion failures when showing hit test debug view on platforms
1885  such as 64-bit Linux.
1886
[2c5ec88]1887* aven: When viewing from above, show "Plan" above the "clino" which indicates
1888  the tilt angle (instead of "Elevation -90°").
1889
[5c676e2]1890* aven: The extended font data now loads faster, and also uses less memory on
1891  64-bit platforms.
1892
[ea59b58]1893* aven: Dragging the vertical divider between the side panel and the 3D view
1894  now only updates when you finish the drag, as redrawing continuously just
1895  looks clunky except on an ultra-fast machine.
1896
[2c5ec88]1897* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
1898  the space available in the aven UI.
1899
[1efeb6d]1900* cavern: Add a *cs command to allow setting the coordinate system for *fix
1901  commands, and the coordinate system used for processed survey data.  The
1902  latter is now stored in 3d v8 format files.
[ea59b58]1903
[515b83e]1904* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
1905  and handle it in the same way as the "DUPLICATE" flag in .svx files.
1906
[6a87cce]1907* cavern: If there's more than one *fix command with coordinates, still
1908  actually fix the second and subsequent ones, to avoid triggering bogus errors
1909  about unconnected surveys.
1910
1911* cavern: If there's more than one *fix command with coordinates, report the
1912  station name of the previous one, plus the file and line number where it was.
1913
[67a0fc6]1914* cavern: Fix handling of the rather contrived case of *fix with no coordinates
1915  followed by *solve and then another *fix with no coordinates not to access
1916  freed memory.
1917
[1efeb6d]1918* dump3d: Report any specified coordinate system.
1919
1920* doc/3dformat.htm: Update to document how the coordinate system is stored.
1921
[2c5ec88]1922* (Microsoft Windows version): Include dump3d in the installer.
1923
[5c676e2]1924* Fix a compiler warning.
1925
1926* Improve test coverage.
1927
[0d365be]1928Changes in 1.2.13 (2014-05-15):
[acbb5b1]1929
[8ccd1d8]1930* aven: Fix --print option to wait for printing to happen before exiting
1931  (previously it would exit right after opening the print dialog, so you
1932  couldn't actually print anything out using it).
1933
[acbb5b1]1934* aven: Increase the threshold for how close the pointer needs to be to a
1935  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
1936  Hugh St Lawrence.
1937
[0d365be]1938* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]1939  if increasing the minimum pointer to station threshold helps Hugh's problems
1940  with using aven on a touch screen device.
1941
[acbb5b1]1942* aven: The measuring line was unable to see stations which had just been
1943  revealed by toggling surface or underground legs on - this is now fixed.
1944
1945* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
1946  many entries are in each box (toggled by F3).
1947
1948* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
1949  off and back on.
1950
1951* aven: Create the empty hit-test grid data structure lazily, to reduce start
1952  up time a little.
1953
1954* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
1955  and *end commands to instead talk about "survey names".
1956
1957* cavern: For ages cavern has warned if you reentered a survey, but this
1958  warning was suppressed if it occurred at the same line of the same file as
1959  the survey was first entered, but this can only happen if you include the
1960  same survey file more than once, which isn't a sensible thing to do for a
1961  file with actual survey data in (you might reasonably do it to set up survey
1962  grade details or something like that).  The warning is now given in this
1963  situation too.
1964
1965* cavern: After 5 warnings about reentering a survey we give up warning about
1966  it, but we used to keep reporting where the survey was originally entered -
1967  this secondary diagnostic message is now silenced when the main message is.
1968
1969* (Microsoft Windows version): Compile C code with optimisation on.
1970
1971* Add the start of a Russian translation, with messages take from therion.
1972
1973* Minor translation updates to French.
1974
1975* Fix compiler warning from GCC.
1976
1977* Testsuite improvements:
1978
1979  + Test that "..." anon station works.
1980
1981  + cavern.tst: Check number of errors returned by all testcases which should
1982    fail and give an error count.
1983
1984  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
1985
[ad727d8]1986Changes in 1.2.12 (2014-04-14):
[46d12e9]1987
[63e8642]1988* aven: Fix measuring line to show change in altitude rather than altitude
1989  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
1990  Clipstone.
[46d12e9]1991
[ad727d8]1992* aven: Fix printing when built with wxWidgets 3.0.
1993
1994* aven: Several visual improvements to printouts:
1995
1996  + Move the numbers below the scale bar down a little so that they don't
1997    overlap the scale bar ticks.
1998
1999  + Set the clipping region after we draw the page border and info box to avoid
2000    clipping the border in print preview.
2001
2002  + Tidy up the appearance of the compass and elevation arrow.
2003
[63e8642]2004* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
2005  <http://bugs.debian.org/739332>.
[46d12e9]2006
[63e8642]2007* aven: Fix to build with older libav where avcodec_free_frame() isn't
2008  available.
[46d12e9]2009
[ad727d8]2010* (Linux version) survex.spec: Update spec file used for building RPM packages.
2011
2012* (Unix version): Add "Keywords:" entry to .desktop files.
2013
2014* (Unix version): Enable large file support, mostly to support filing systems
2015  which return 64 bit inode values, such as CIFS mounts.
2016
[63e8642]2017* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
2018  rather than any character which is a letter in the current locale.
[46d12e9]2019
[63e8642]2020* Various translation updates.
[46d12e9]2021
[aac3336]2022Changes in 1.2.11 (2014-01-28):
[fb941bfd]2023
2024* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
2025  Reported by Kevin Dixon.
2026
[aac3336]2027* aven: Embed the font data for the first 256 Unicode characters for use in the
2028  survey pane into the compiled aven binary to reduce start up overhead.  Any
2029  additional characters needed are loaded from a data file only if/when a
2030  character >= U+100 is actually needed (as before).
2031
[ad3017d]2032* aven: Fix display of Unicode characters above 256 when there's a character
2033  <= 256 earlier in the same string.
2034
[77bdacf]2035* aven: Use the actual width of Unicode characters above 256 rather than
2036  assuming they are 16 pixels wide.
[ad3017d]2037
2038* aven: If full screen, don't show the side panel when a new file is opened
2039  (e.g. via Ctrl+O).
2040
2041* aven: Don't give an assertion failure when showing passages for a cave with
2042  no vertical extent.  Reported by Jonny Prouty.
2043
2044* aven: Change terminology in print dialog - say "legend" instead of "info
2045  box".
2046
2047* aven: Add option to show the tilt angle as a percentage gradient.
2048
2049* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
2050  indicators.
2051
2052* aven: All length units are now translatable.
2053
[fb941bfd]2054* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
2055  will reduce code size and also the number of deprecation warnings about
2056  gluErrorString on Mac OS X 10.9.
2057
[ad3017d]2058* (Microsoft Windows version): aven: Try to work around redraw issues related
2059  to the measuring line by redrawing the whole window, which doesn't seem to be
2060  measurably slower.
2061
2062* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
2063  give an error rather than quietly ignoring the attempt.
2064
[77bdacf]2065* cad3d: Make cad3d remap control characters and spaces in station names when
2066  generating PLT output in the same way aven does.
2067
[ad3017d]2068* Various translation updates (particular thanks to Eric Madelaine and Dennis
2069  Baudys), including the start of a Bulgarian translation, with messages taken
2070  from Therion and elsewhere.
2071
2072* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
2073  GetUserDefaultUILanguage() to get the UI language to use.  For older
2074  versions, continue to use GetUserDefaultLCID().
[fb941bfd]2075
2076* (Microsoft Windows version): The Indonesian translation will now be used
2077  automatically when the system language is set to Indonesian.
2078
2079* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
2080  A. Riggs for his work on this.
2081
2082* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
2083  checksum check for the downloaded wx sources.
2084
2085* Fix a lot of the compiler warnings when building with clang.
2086
[ad3017d]2087* doc/manual.sgml: Add missing quantities to the list documented as accepted by
2088  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
2089  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
2090  mentioned in list of the units that can be set for them); COUNT (missing
2091  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
2092  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
2093
2094* Test suite: Improve test coverage for cavern.
2095
[0ecf3b1]2096Changes in 1.2.10 (2014-01-15):
2097
2098* aven: Fix assertion if two mouse buttons are held down at the same time.
2099  If dragging with more than one mouse button held down, releasing one causes
2100  another which is still held down to take effect.  Reported by Brian
2101  Clipstone.
2102
[53966d3]2103* aven: If we fail to start the external editor when the user clicks on an
2104  error or warning from cavern, show an error box.
2105
[6f0d0d8]2106* aven: If the survey has a title, add it as a top-level <title> element to
2107  exported SVG files.
2108
2109* aven: Escape '<', '>', and '&' in labels in exported SVG files.
2110
2111* aven: In GPX export, set the <time> element to the datestamp from the 3d
2112  file.
2113
2114* aven: Don't try to write the title if it isn't set or is empty when exporting
2115  GPX files.
2116
2117* aven: Don't bother looking up the printer page setup info when exporting.
2118
[0ecf3b1]2119* (Microsoft Windows version): aven: Fix crash on "File->Print" or
2120  "File->Export" under Windows XP, reported by Brian Clipstone.
2121
2122* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
2123  encoded filename which could occur if run without being asked to load a file
2124  on startup.
2125
2126* (Microsoft Windows version): aven: Compile with optimisation on.
2127
2128* img library, aven: Although processed CMAP data files are often referred to
2129  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
2130  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
2131  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
2132  continue to do so in case anyone is relying on it, but also check for the
2133  other extensions.
2134
2135* img library: Add new "datestamp_numeric" field to struct img giving the
2136  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
2137  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
2138  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
2139  timezone wrong.
2140
2141* img library: Fix my_strcasecmp() to handle top-bit set characters better.
2142
[6f0d0d8]2143* cavern: Fix NULL pointer dereference when processing Compass DAT file without
2144  'SURVEY DATE:'.
[0ecf3b1]2145
[6f0d0d8]2146* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]2147
[6f0d0d8]2148* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]2149
[53966d3]2150* Fix some compiler warnings if built with glibc's fortify source feature
2151  enabled.
2152
[6b6fb4d]2153Changes in 1.2.9 (2014-01-08):
2154
2155* Document --3d-version in cavern man page and the manual.
2156
2157* aven: Fix compilation error in movie export code with recent libavi.
2158
2159* aven: Fix warning on stderr when export a movie as MPEG.
2160
2161* img library: In non-hosted mode, don't define GETC and PUTC if they're
2162  already defined, to allow easy overriding with getc_unlocked() and
2163  putc_unlocked() (which are significantly faster on Linux).
2164
2165* img library: In non-hosted mode, check that int is at least 32 bits,
2166  and if not, use long.  In practice, platforms with 16 bit int are mostly
2167  obsolete, but it's not hard to be portable here.
2168
2169* img library: Add test that img.c and img.h compile in non-hosted mode
2170  (regression test for issue fixed in 1.2.8).
2171
2172* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
2173
2174* Update translations from launchpad and from existing similar messages.
2175
2176* Fix some compiler warnings.
2177
[e1f27c4]2178Changes in 1.2.8 (2013-10-29):
[da65891]2179
2180* cavern: Fix handling of anonymous wall stations ('..' by default) to
2181  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
2182  Holder.
2183
[e1f27c4]2184* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]2185  statistics when the value gets large.
2186
[a4adf09]2187* cavern: Eliminate redundant progress message when solving simultaneous
2188  equations.
2189
[e1f27c4]2190* aven: Add a format drop down to the export dialog, and only show fields which
2191  are meaningful and supported for the currently selected export format.  The
2192  format defaults to that used most recently.  The "Elements" and "View" boxes
2193  have been swapped in the print and export dialogs as that layout works much
2194  better when the "View" box is hidden.
2195
[0056ee1]2196* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
2197  - now works again.  Reported by Anthony Day.
2198
[e1f27c4]2199* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
2200  this release the projection which the survey coordinates are in defaults
2201  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
2202  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
2203  projection string.  The ability to specify this projection in a better
2204  way is coming soon.
2205
2206* aven: New export options "Origin in centre" and "Full coordinates" - the
2207  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
2208
2209* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
2210  time ago, so update references.
2211
2212* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
2213  with wxMSW 2.9.5.  Reported by Brian Clipstone.
2214
2215* aven: Make right click in an empty presentation mark the current position and
2216  open it to edit, instead of crashing.
2217
2218* aven: Update movie export code to work with latest libav API.  Reported by
2219  Sebastian Ramacher.
2220
2221* aven: Improve reporting of errors during the process of exporting a movie.
2222
2223* aven: Don't try to close the movie if we aren't producing one.
2224
2225* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
2226
2227* aven: Fix to build with wxMSW 2.9.5.
2228
2229* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
2230
2231* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
2232  ago, so add a new --skencil option to specify this output format.  The old
2233  name (--sketch) is still recognised for compatibility.
2234
2235* cad3d: Make --marker-size work for Skencil and SVG output.
2236
2237* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]2238
[88b54df6]2239* img library:
2240
[e1f27c4]2241  + Fix to work once more when used outside of Survex (missing definition of
2242    max() macro and a bad call to free() in img_close() for a file opened for
2243    reading).
2244
2245  + Use lround() instead of round(), and make the tests around whether we use
2246    the library function or the our fallback implementation saner.
2247
2248  + Fix // comments in C code for portability to pre-C99 compilers which don't
2249    support these as an extension.
[88b54df6]2250
[f807d8bf]2251  + Can now be compiled as C++ as well as as C.
2252
[e1f27c4]2253* (Microsoft Windows version): The installer is now built with a newer version
2254  of Innosetup, and includes translations for all the languages which Survex
2255  itself has any translations for.
2256
2257* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
2258
2259* Minor translation updates.
2260
2261* tests/Makefile.am: Distribute files for "normal_bad" testcase.
2262
[e34bebc]2263Changes in 1.2.7 (2013-07-27):
[65d9b6b]2264
[e34bebc]2265* Add support for anonymous stations, which are indicated by one, two or three
2266  separator characters - with the default separator of '.', that means '.',
2267  '..', and '...' are anonymous stations.  Single separator ('.' by default)
2268  is an anonymous non-wall point, double separator ('..' by default)
[a5c74f2]2269  is an anonymous wall point at the end of an implicit splay), and triple
2270  separator ('...' by default) is an anonymous point (with nothing special about
[e34bebc]2271  the leg).  A new *alias command allows '-' to be mapped to '..' for
2272  compatibility with pocket topo: *alias station - ..
[07beaa4]2273
[e34bebc]2274* New version 8 of the 3d format:
[07beaa4]2275
[e34bebc]2276  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]2277
[e34bebc]2278  + New explicit file-wide flag for 'this is an extended elevation', rather
2279    than modifying the survey title to indicate this.
[da9d788]2280
[e34bebc]2281  + The survey prefix is often unchanged from one leg to the next, so use a
2282    spare flag to compactly indicate when there's no label change.
[da9d788]2283
[e34bebc]2284  + The data style of each leg is now stored.
[da9d788]2285
[e34bebc]2286  + The "processed at" time is stored as seconds since 1970 rather than a
2287    human-readable string.
[da9d788]2288
[e34bebc]2289  + Since 3d v8 features significant changes to the format, the format
2290    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]2291
[e34bebc]2292* img library:
[da9d788]2293
[e34bebc]2294  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]2295
[e34bebc]2296  + Handle .pos files containing unnamed stations - don't suck the next line in
2297    as the station name, and set img_SFLAG_ANON for them.
[da9d788]2298
[e34bebc]2299  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
2300    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
2301    elevation, in place of appending " (extended)" to the title.  Internally we
2302    still append this to the title (and remove it upon reading) when writing
2303    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
2304    explicitly in the file.
[da9d788]2305
[e34bebc]2306  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]2307
[e34bebc]2308* aven:
[da9d788]2309
[e34bebc]2310  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
2311    now, and the wx developers consider even 2.8 to be rather long in the
2312    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
2313    formally dropping support for older versions allows a number of workarounds
2314    to be removed from the aven source code.  Also, features deprecated in
2315    wxWidgets 2.9 are no longer used in our code.
[da9d788]2316
[e34bebc]2317  + Don't run incremental search on every key-press, as on a slow machine the
2318    short initial search(es) will take a while but not be useful.  Instead only
2319    actually run the search when we're told there are no more key-presses
2320    queued up.
[da9d788]2321
[e34bebc]2322  + Implement support for including cross-section information in exported SVG
2323    and DXF files (ticket#4).  The DXF export is untested currently.
2324
2325  + Show splay legs faded by default, with menu options to hide them or show
2326    them like other legs.
2327
2328  + Speed up loading a .3d file with cross-sections by using a map to convert
2329    station names to positions.
2330
2331  + In the cavern log window, don't highlight a file:linenumber if there's no
2332    message after it, which avoids highlighting the "Included from" lines
2333    wrongly.
2334
2335  + Fix not to crash when trying to report an error while starting up.
2336
2337  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
2338    the OS X standard shortcut Shift-Command-F (previously we used F11, but
2339    that's used by the desktop).
2340
2341  + Add checks for errors when reading the font file.
[07beaa4]2342
[e34bebc]2343  + Remove useless extra quoting when invoking vim to show the location of an
2344    error from cavern.
[07beaa4]2345
[e34bebc]2346  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]2347
[e34bebc]2348  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2349    in the dialog in sync.
[da9d788]2350
[e34bebc]2351* cavern:
[3dfffa2]2352
[e34bebc]2353  + Demote errors about invalid dates to warnings, since we've accepted *date
2354    for ages without any checks on the value, and so existing datasets
2355    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]2356
[e34bebc]2357  + New *alias command allows '-' to be mapped to '..' for compatibility with
2358    pocket topo: *alias station - ..
[07beaa4]2359
[e34bebc]2360  + We want to warn if there's a clino reading which it would be impossible to
2361    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2362    read "93" (it's probably a typo e.g. for "39").  However, the gradient
2363    reading from a topofil is typically in the range 0 to 180, with 90 being
2364    horizontal.  Really we should allow the valid range to be explicitly
2365    specified, but for now we infer it from the zero error - if this is within
2366    45 degrees of 90 then we assume the instrument can read between 0 and 180
2367    degrees.
[da9d788]2368
[e34bebc]2369  + If the survey isn't all connected, still run survey tree checks and report
2370    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
2371    Dixon for the report which highlighted this issue.
[da9d788]2372
[e34bebc]2373  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]2374
[e34bebc]2375  + Report column numbers as well as line numbers for some cavern errors and
2376    warnings.
[07beaa4]2377
[e34bebc]2378  + Adjust width of node stats table to fit longest count when there are more
2379    than 9999 of a particular order of node.
[07beaa4]2380
[e34bebc]2381  + If the argument to *include has an opening double quote but the closing
2382    double quote is missing, then skip trying to open the file.
[da9d788]2383
[e34bebc]2384  + Move "Station X referred to just once" warning after non-existent survey
2385    check - if both fire, the non-existent survey error is likely to be more
2386    relevant.
[da9d788]2387
[e34bebc]2388  + We no longer follow an error for a bad reading in passage data with a bogus
2389    "End of line not blank" error, but instead check the remaining readings on
2390    the same line.
[da9d788]2391
[e34bebc]2392  + We no longer follow an error about OMIT for a required reading with a bogus
2393    "End of line not blank" error.
[7f6250a]2394
[e34bebc]2395  + Report an error if the scale factor in *calibrate is zero - it doesn't make
2396    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]2397
[e34bebc]2398  + Report the parent include files starting from the outermost, as that's more
2399    logical when there are multiple levels involved.
[07beaa4]2400
[e34bebc]2401  + If we were expecting a numeric field and instead get something which starts
2402    with '+', '-', or '.' but which isn't a number, then fix the error to
2403    include that character in the token reported.
[3dfffa2]2404
[e34bebc]2405  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2406    first item.
[07beaa4]2407
[e34bebc]2408* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]2409
[e34bebc]2410* dump3d:
[07beaa4]2411
[e34bebc]2412  + Build, install and package dump3d as standard - it's useful for grabbing
2413    info from 3d files in scripts.
[07beaa4]2414
[e34bebc]2415  + Add --show-dates option.
[07beaa4]2416
[e34bebc]2417  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]2418
[e34bebc]2419  + Report the data style of legs.
[da9d788]2420
[e34bebc]2421  + Report if the file is an extended elevation.
2422
2423  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]2424
2425* Test suite:
2426
2427  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2428    expected output so it passes reliably.
2429
[e34bebc]2430  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2431    'Deleted' stations upon failure are the more natural way round.
2432
[07beaa4]2433  + Add more testcases, expand some existing testcases, and add expected output
2434    for more.
2435
[e34bebc]2436* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2437  appropriate C and C++ compilers to use, and link mingw build statically to
2438  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]2439
2440* (Unix version): When determining the character set for command-line tools,
2441  check environmental variable LANG after LC_ALL and LC_CTYPE.
2442
2443* When determining the language, check environmental variable LC_ALL before
2444  LC_MESSAGES and LANG (but after SURVEXLANG).
2445
[e34bebc]2446* If we don't find the message file, only give an error if it was specified
[665183c]2447  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]2448  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2449  settings.
2450
2451* There are a handful of hard-coded English message strings for reporting
2452  errors trying loading message files, etc.  These are all now ASCII, as if we
2453  fail trying to open a message file, it's more likely the encoding isn't
2454  set correctly.
2455
2456* Prune strings we are no longer using and are probably unlikely to use again
2457  into a new file po_codes_dead, so that translators don't get presented with
2458  them to translate.
2459
[07beaa4]2460* Merge lots of translation updates.  Most translations are now complete or
2461  close to complete.
[3dfffa2]2462
2463* Add start of Indonesian translation from Arief Setiadi Wibowo.
2464
[07beaa4]2465* Fix various compiler warnings when building from source.
2466
[e34bebc]2467* Include scripts gdtconvert and gen_img2aven in the source distribution.
2468
[c575465]2469Changes in 1.2.6 (2012-02-23):
[b081031]2470
2471* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2472
2473* (Microsoft Windows version): Include JPEG images for aven in the installer
2474  package (ticket#35).
2475
2476* cavern: If we have a reference to a station in a non-existent survey, give a
2477  helpful error rather than saying the station hasn't been exported from the
2478  survey.  (Bug reported by Martin Green via email)
2479
2480* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
2481  Kahler.
2482
2483* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]2484  .gpx file with waypoints for entrances.  This needs libproj so is disabled
2485  by default for this release - to enable it install the development stuff for
2486  libproj and build survex with:
2487
2488      make FINDENTRANCES=findentrances
2489      make install FINDENTRANCES=findentrances
[b081031]2490
2491* dump3d: Add support for showing img_ERROR_INFO items.
2492
2493* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2494
2495* Incorporate a French translation from launchpad I'd previously copied the
2496  English version of by mistake.  Attempt to correct mistranslation of "survey
2497  file".
2498
[685116f]2499Changes in 1.2.5 (2012-01-03):
2500
2501* aven:
2502
2503  + The survey tree in the left panel is now in sorted order once more.
2504
2505  + No longer fails with an assertion if used for a long time (we were leaking
2506    an OpenGL list each time one had to be regenerated).
2507
2508  + Now builds with newer FFmpeg library.
2509
2510  + Draw measuring line in front of the indicators rather than behind them.
2511
2512  + Loading a new file (or reloading the current one) no longer invalidates
2513    the OpenGL lists for the compass and clino, so will be a fraction faster.
2514
2515* Improve handling of attempts to look up translated messages before the
2516  message subsystem is fully initialised (which only happens if there's an
2517  error early on).
2518
2519* Improve the survex(7) man page text, and fix it to be marked as section 7 in
2520  the man page source as well as in the filename.
2521
[f15ca67f]2522Changes in 1.2.4 (2012-01-01):
2523
2524* aven:
2525
2526  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2527    initialised, which doesn't cause problems in some machines, but causes aven
2528    to abort on others.  This is now fixed, and there's a check in place to
2529    help avoid similar issues in future. (ticket#34)
2530
2531  + Always use metres or feet for the depth colour key, and chose a consistent
2532    precision by looking at the depth range. (ticket#30)
2533
2534  + Show the depth units below the colour bar rather than after every value.
2535
2536  + When zooming way in, stay in metres rather than switching to cm.
2537
2538  + On the scale bar, say “1 mile” rather than “1 miles”.
2539
2540* Translation updates for Catalan, French and Slovak.
2541
[5b9942e]2542Changes in 1.2.3 (2011-12-31):
2543
2544* Fix to build with wxWidgets 2.9.2.
2545
2546* (Mac OS X version):
2547
2548  + Processing .svx files from aven now works.
2549
2550  + Remove spurious blank lines from the licence text in "Get Info".
2551
2552  + Don't create the help menu at all, as it is empty (because the "About"
2553    entry goes elsewhere) and sometimes seems to appear in the UI.
2554
2555  + INSTALL.OSX: Update to reflect current status.
2556
2557* aven:
2558
2559  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
2560
2561  + Improvements to text plotted on the survey pane:
2562
2563    - Support plotting Unicode character points > 256 by lazily loading the
2564      data for them from the font file and plotting them with a direct call to
2565      glBitmap(), which is slower but doesn't require a display list per
2566      character.
2567
2568    - Adjust the spacing from fixed width to putting a one pixel gap either
2569      side of each one character (so two between adjacent glyphs).  Mostly this
2570      reduces the horizontal width, but it adds a pixel for characters like "m"
2571      and two in a few cases.
2572
2573    - Fix .pixelfont file generation to correctly handle characters wider than
2574      8 pixels.
2575
2576  + Fix expected cross shape so don't always reject using texture mapping to
2577    draw crosses.
2578
[3ea0178]2579  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2580    as those consisting of just one.  Previously we would trip over the empty
2581    tube later.  Such tubes can for example be created by extend if a splay shot
2582    is the start or end of a tube.
2583
[5b9942e]2584  + Make the green colour used for entrances in the survey tree the same
2585    (slightly darker than before) green used for the entrance blobs.
2586
2587  + Report the version of the library we're actually running with if built
2588    against wx >= 2.9.2.  Make it clear that the version reported is the
2589    version *built* with for wx < 2.9.2.
2590
[3ea0178]2591* extend:
2592
2593  + Copy the end markers for passage tubes.
[5b9942e]2594
[3ea0178]2595  + Preserve left and right data for tubes (previously they were set to -1.0
2596    which means "no info").
2597
2598* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2599  was no longer used - it certainly is!
2600
2601* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2602  messages, and curly single right quote instead of straight ASCII apostrophe.
2603  Fall back to using straight ASCII versions if we can't represent them in the
2604  current character set.
[5b9942e]2605
[3ea0178]2606* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]2607
2608* Test suite:
2609
2610  + Add test coverage for interleaved diving data.
2611
2612  + Add testcase for diving data with topofil-style distance.
2613
[94960ad]2614Changes in 1.2.2 (2011-10-06):
2615
2616* aven:
2617
2618  + Replace the textured-mapped font drawing with an approach based on
2619    glBitmap.  This doesn't suffer from the character alignment issues which
2620    the textured-mapped fonts had, and is actually significantly faster on some
2621    machines.  The current font used is (mostly) fixed-width, but this isn't an
2622    inherent limitation - it was just the easiest font data to convert to a
2623    usable format.
2624
2625  + Fix assertion failure due to rounding differences on loading certain .3d
2626    files.  (ticket#26)
2627
2628  + Fix assertion failure when turning on 3D passages if they stick out higher
2629    or lower than any station.  (ticket#29)
2630
[53f8a93]2631  + Fix grid not to disappear when blobs are turned on and blobs are drawn
2632    using lines.
2633
[94960ad]2634  + If a degree sign isn't available in the character set in use, transliterate
2635    it to 'dg' rather than skipping it.
2636
2637  + Fix message which should have been a degree sign but got lost in the format
2638    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
2639    that bearings in the status bar now have a degree sign after them if they
2640    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2641
2642  + Fix print dialog to calculate the scale required for "One page" right
2643    before it calculates how many pages are required, so we don't end up
2644    something other than 1x1 being shown when the user changes settings.
2645
2646  + Update the calculations for picking a scale and for deciding how many
2647    pages are needed to take into account the change in info box height made
2648    in 1.2.1.
2649
[9704252]2650Changes in 1.2.1 (2011-10-04):
[e3c58c3]2651
2652* Translation updates for US English.
2653
2654* aven:
2655
2656  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2657    it now shows colours for dates and errors as well as depths.
2658
2659  + In the colour key for "colour by date", change "No info" to "Undated".
2660
2661  + Remove the dark grey background from the colour key and just put a single
2662    pixel black border around the colours.  This is more in keeping with the
2663    other controls, and means the colours are now on a black background so more
2664    visually similar to the survey legs.
2665
2666  + Move the colour key's "Undated"/"Not in loop" entry down a little to
2667    improve the appearance.  Make each section a pixel taller.
2668
[9704252]2669  + Allow "Colour by X" to be selected even if there's no data for X or only a
2670    single value of X used (the colour key is much smaller in these cases, and
2671    does still provide some useful information).
2672
2673  + Fix incorrect calculation of depth colouring for survey legs which straddle
2674    a depth band boundary.
[e3c58c3]2675
2676  + The scale bar, compass, clino, and colour key now all have right click
[9704252]2677    menus which allow related actions to be performed (especially handy in
2678    full-screen mode).
[e3c58c3]2679
2680  + Improve the font used on the survey pane - it now contains the '-'
2681    character (so the clino now shows negative angles as negative, and dates
2682    in the colour key are now hyphenated).  Also the spacing and alignment
2683    are a little better, though still not perfect.
2684
2685  + PLT file export now handles spaces and control characters in station names
2686    by escaping them with '%' as in URLs.
2687
2688  + Pressing "Enter" on a station in the tree control now centres the view on
2689    that station.
2690
2691  + The scale bar is now cached in an OpenGL display list since it often gets
2692    redrawn exactly the same - for example, when rotating, panning, etc.
2693
2694  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2695    then forces a refresh of the survey pane.  This is intended as a debugging
2696    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]2697    where a list should have been invalidated (please report if you find such
2698    a case as it is a bug).
[e3c58c3]2699
[9704252]2700  + We now automatically track which OpenGL display lists need to be
2701    invalidated on window width or height changes.
[e3c58c3]2702
2703  + Increase scale bar maximum width from 65% of the window width to 75% as it
2704    was in 1.0.x (except that if that would overlap the clino we now reduce
2705    that proportion down until it reaches 50%).  Make the limit of zooming in
2706    the same as in 1.0.x.  (ticket#23)
2707
[9704252]2708  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2709    the application was fullscreen (the dialog got opened under the main
2710    window!)  To work around this, aven would switch out of full screen mode
2711    temporarily while showing a dialog.  This case works properly with recent
2712    wxGTK, so disable our workaround with versions we know work.  Also, apply
2713    the workaround only for wxGTK, not everywhere except on Microsoft Windows
2714    as there's no reason to think we need it for other platforms.
[e3c58c3]2715
2716  + Grey out the "View North" action when we're already viewing North, and
2717    similarly for other compass points.
2718
2719  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
2720    info in the "About" dialog.
2721
2722  + Fix to set the correct filename on the root of the survey tree - previously
2723    the filename of the previous file loaded was used!
2724
2725  + The movie export code now works with newer versions of the FFmpeg libraries
2726    as well as still working with older versions.
2727
2728  + Fix mixed up messages - the print dialog now says "View" on the left
2729    subgroup of controls rather than some unrelated message.
2730
2731  + On printouts, combine the "Plan View"/"Elevation" info box field with the
2732    field which gives the bearing and reduce the height on the info box by the
2733    removed field, so it's now 3cm for plans and elevations, as for extended
2734    elevations.  Report the tilt angle for tilted elevations which it seems has
2735    been missing for ages (it's not in recent 1.0.x either).
2736
2737  + Tweak the exact positioning of informational text on printouts to look
2738    nicer and make better use of the available space.
2739
2740  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
2741    dialog.
2742
2743  + Make the sign of the tilt angle for printouts consistent with the sign
2744    shown by the "clino" in the survey pane.
2745
2746  + In the "Print" dialog, when in plan view disable the "Plan view" button,
2747    and similarly for the "Elevation" button.
2748
[9704252]2749  + (Microsoft Windows version): Sort out appearance of custom cursors.
2750
[e3c58c3]2751  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
2752
2753  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
2754    you can't get out again easily, so add code to explicitly check for F11
2755    being pressed and toggle full screen.
2756
2757* (Linux version): Fix the RPM .spec file for where man pages now get installed
2758  and package aven.svg and the vim support files.  (Fixes from James Begley)
2759
2760* "make check" now performs several checks on the translation files.
2761
2762* More messages are now available to be translated.
2763
2764* cavern: Fix reporting of ranges of survey coordinates, which was broken by
2765  the message handling changes in 1.2.0.
2766
2767* Fix warning when compiling with GCC.
2768
2769* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
2770  sudo for installing on Unix.
2771
2772* In the manual, replace the instructions for building from source with a
2773  pointer to the clearer instructions in INSTALL.
2774
2775* In the manual, make it clear that installing with administrator rights
2776  also applies to newer platforms than XP.
2777
2778* doc/TODO.htm: Update.
2779
[120c1c6]2780Changes in 1.2.0 (2011-09-20):
[b4ac7007]2781
2782* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
2783  English.
2784
[9cfcb3f]2785* tests/smoke.tst: aven no longer requires an X display for --help or
2786  --version, so replace skip of this check with a check that this remains the
2787  case.
2788
2789* We now use the standard .po and .pot file formats for storing translations
2790  (rather than the Survex-specific messages.txt format), and then translate
2791  these into Survex's .msg format.
2792
[b4ac7007]2793* (Unix version): Move survex man page to section 7 (since it isn't documenting
2794  an actual command).
2795
[9cfcb3f]2796* (Unix version): Write each generated man page to a temporary file, then
2797  atomically rename, to avoid leaving an empty or partial man page behind if
2798  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
2799  recurrence of that).
2800
[b4ac7007]2801* (Unix version): Default to installing docs into /usr/share/doc/survex rather
2802  than /usr/doc/survex.
2803
2804* aven:
2805
[120c1c6]2806  + Fix handling of accented characters in the survey pane.
2807
[9cfcb3f]2808  + Aven icon redrawn in SVG format - it's now a vector image which looks
2809    nicer at larger sizes.
2810
[b4ac7007]2811  + Explicitly request double-buffering, which seems to be needed for systems
2812    with GLX >= 1.3.
2813
2814  + Fix crash while trying to load certain .3d files.
2815
2816  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]2817    Currently this is disabled in Microsoft Windows builds, pending getting the
2818    required libraries set up for building releases.
[b4ac7007]2819
2820  + Reporting of errors during movie export improved.
2821
2822  + Force playback speed to "x1" during movie export.
2823
2824  + Use stock IDs for buttons where appropriate - such buttons may now be
2825    rendered with icons on some platforms.
2826
[9cfcb3f]2827  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
2828    ISO8859-1).
2829
2830  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
2831    as it's no longer required with modern versions.
2832
2833  + Don't redraw the survey on every mouse movement in the survey pane unless
2834    the measuring line is (or just was) active.  (ticket #17)
2835
[b4ac7007]2836* cavern:
2837
2838  + Drop "non-fatal" from the report of how many errors there were at the end
2839    of the run - it just confuses users - we won't even get here if there's a
2840    fatal error!
2841
[9cfcb3f]2842  + Add --3d-version option to allow the user to specify the version of the 3d
2843    format to output.  (ticket#21)
2844
2845* img library:
2846
2847  + Make the highest and lowest valid values for img_output_version available
2848    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
2849
[b4ac7007]2850* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]2851  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]2852
[8f9b0b6d]2853Changes in 1.1.16 (2011-05-16):
[ecdb631]2854
2855* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
2856  Portuguese, and US English.
2857
2858* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]2859  rather than '->' where these characters are available.
[ecdb631]2860
2861* (Unix version): Link with -lGL, if it exists, to support linking with gold or
2862  GNU ld --as-needed (Debian bug #615781).
2863
2864* img.c:
2865
2866  + Fix code typo for IMG_API_VERSION == 0 case.
2867
2868  + Fix code typo in code used when IMG_HOSTED isn't defined.
2869
2870* doc/TODO.htm: Remove entries which have now been done.
2871
[8f9b0b6d]2872* (Microsoft Windows version): aven: We now include all the available
2873  translations for messages from wxWidgets, which means that standard widgets
2874  will appear translated where available even if Survex messages aren't
2875  translated.
2876
[f5e3521]2877Changes in 1.1.15 (2010-10-15):
[2d16e4e]2878
2879* aven:
2880
2881  + In the cavern log window, change the "Rerun" button to "Reprocess" to
2882    follow terminology in manual and elsewhere.  Fixes ticket#15.
2883
2884  + When displaying output from cavern, don't update the window after every
2885    line, but only when we don't have data from cavern pending.  Hopefully
2886    addresses ticket#12.
2887
2888  + If we aren't using GL_POINTS for blobs, draw them using a series of
2889    abutting lines rather than with gluDisk which is faster and gives a
2890    consistent shape.
2891
2892  + Check whether blobs and crosses actually render correctly as points/point
2893    sprites, and if they don't, fall back to drawing them with lines.  The
2894    best method is cached on disk, and rechecked automatically if the graphics
2895    hardware is changed or the drivers upgraded.
2896
2897  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
2898    though, so we still enable USE_FNT by default).
2899
2900  + Don't offer "All files" wildcard in presentation save dialog.
2901
2902  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
2903    more places.
2904
2905  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]2906    when running cavern from aven.  Fixes ticket#11.
2907
2908* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
2909
2910* diffpos: Handle files with duplicate labels in better - extend generates
2911  duplicate labels when it breaks a loop.
2912
2913* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]2914
2915* New v7 of .3d format which stores survey dates as number of days since
2916  January 1st 1900, so we now support dates from 1900-2078 (rather than
2917  1970-2037) with a smaller file size.  The img API is now versioned - you
2918  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
2919  gives the survey dates in days in days1 and days2 instead of as time_t
2920  values in date1 and date2.  Fixes ticket#14.
2921
2922* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
2923  former has been the canonical name for some time, with www.survex.com just
2924  redirecting to it.
2925
2926* (Unix version): Use unlocked file I/O if available, which can be much faster
2927  in some cases (we don't need the locking as we don't do multithreaded file
2928  I/O).
2929
2930* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
2931  headers.
2932
2933* (Mac version): buildmacosx.sh now works again.
2934
2935* Most tests weren't actually running any testcases (looks like a sh
2936  portability issue).  This is now fixed, and fortunately all tests still pass.
2937
2938* Include the extra .isl translation files for Innosetup in the source archive.
2939
[f9473ab]2940Changes in 1.1.14 (2010-07-26):
2941
2942* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
2943
2944* aven:
2945
2946  + After processing survey data, if there were warnings or errors, add a
2947    "Rerun" button to allow easy reprocessing after fixing problems.  If there
2948    were only warnings, also add an "OK" button to allow moving on to viewing
2949    the processed survey data (fixes ticket#13).
2950
2951  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
2952
2953  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
2954    not the ': ' after), and to make the title for the terminal the
2955    warning/error message.  Avoid false positives by checking that '<line>' is
2956    a number.
2957
2958  + Don't double escape the contents of href and target in links in the cavern
2959    log window.
2960
2961  + Improve handling of the splitter window, fixing behavioural glitches in
2962    various cases.
2963
2964  + Highlight stations matching any current search when a file is loaded.
2965    (ticket#9)
2966
2967  + (Mac version): Fix build issue due to Mac OS X polluting the global
2968    namespace with its own "Point" class.
2969
2970  + (Unix version): The Gnome print dialog has its own preview window so
2971    suppress ours if using the Gnome one.
2972
2973  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
2974
2975  + (Microsoft Windows version): Fix handling of a double-click on the survey
2976    tree when built with wxWidgets >= 2.8.11.
2977
2978* cavern: Report relevant file and line number for three warnings which didn't
2979  give them before.
2980
2981* (Unix and Mac versions): configure: Update the wx-config probing code -
2982  wxmac-config etc aren't present with newer wxWidgets versions so there's no
2983  point looking for them now.
2984
2985* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
2986  for easy installation.  Update it to work with the latest Survex versions
2987  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
2988  private wxWidgets, use 2.8.11 not 2.7.0-1).
2989
2990* manual:
2991
2992  + Correctly capitalise "GTK".
2993
2994  + Note that on Linux we only regularly test builds with the GTK+ version
2995    (change taken from 1.0).
2996
2997* Fixed the cad3d man page, which was an empty file in 1.1.13.
2998
[0bd49eb]2999Changes in 1.1.13 (2010-06-16):
[90d0d71]3000
3001* Say "wxWidgets" instead of "wxWindows" consistently.
3002
[739b92c]3003* img.c: Fix small memory leak (filename_opened member).
[90d0d71]3004
3005* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]3006
3007* aven:
3008
[90d0d71]3009  + wxWidgets 2.6.0 or newer is now required.
3010
3011  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
3012    work but hasn't been tested recently (all packaged versions of wxWidgets
3013    seem to be Unicode now).
3014
3015  + Fix potential uses of uninitialised variables which may have been causing
3016    occasional glitches when loading a file on start-up.
3017
[e4bfd2f]3018  + Improvements to the handling of the font used for plotting labels and other
3019    text on the survey pane:
3020
3021    - Loading the font file is more efficient.
3022
3023    - Character spacing is improved.
3024
3025    - Default font is now anti-aliased.
[90d0d71]3026
3027  + "About" dialog:
3028
3029    - Add "Copy" button to copy the system info to the clipboard for easier
3030      bug reporting.
3031
3032    - List OpenGL extensions last, since there are usually lots of them with a
3033      modern gfx card.
3034
3035    - Fix 100% CPU usage while the "About" dialog is open.
3036
3037  + Processing .svx files:
3038
3039    - Passing a .svx file on the command line now works better.
[1324d6c]3040
[739b92c]3041    - Put the survey data log window in a splitter in the usual frame rather
3042      than opening a separate frame for it.
3043
[90d0d71]3044    - Auto-scroll the log window until we've reported a warning or error.
3045
3046    - Fix small memory leak.
3047
3048  + The presentation filename now defaults to using the basename of the
3049    currently loaded dataset, but we always prompt before we first save with
3050    such a name.
3051
3052  + Reduce memory usage when saving a screenshot.
3053
[e4bfd2f]3054  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
3055    persist the window size (and maximised or fullscreen state) between
3056    invocations.
3057
[90d0d71]3058  + Fix reporting of OpenGL errors.
3059
3060  + Fix glitches when tilting while looking East.
3061
[739b92c]3062  + Added Portuguese and Slovak translations of wxWidgets messages.
3063
[90d0d71]3064* Documentation:
3065
[e4bfd2f]3066  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
3067
3068  + Drop the "alternative manual formats" self-extracting zip file - people
3069    will generally just want one of the formats, so downloading several
3070    together isn't very useful.
3071
[90d0d71]3072  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
3073
3074  + GPL.htm: Replace HTML version of licence with a link to the version on
3075    the FSF website.
3076
3077  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
3078    low level to be of interest to non-developers, and developers can look at
3079    the source code.
3080
3081* (Unix version): configure: New preferred name for specifying wx-config script
3082  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]3083
[e4bfd2f]3084* (Linux version): Source RPM package dropped as you can just build an RPM
3085  package from the source tarball.
3086
[739b92c]3087* (Microsoft Windows version): The installer is now created with a newer
3088  version of InnoSetup, which gives a 10% smaller download.
3089
[2e12f8c]3090Changes in 1.1.12 (2007-02-07):
[5940815]3091
3092* aven:
3093
[3db0798]3094  + Remember the window size or maximised/fullscreen state between invocations.
3095
[5940815]3096  + Add options dialog to "Export" similar to the one for "Print".
3097
[6b2113d]3098  + The "number of pages required" in the print dialog now updates when you
3099    change what is to be shown (underground legs/surface legs/station
3100    names/crosses).
3101
[920b066]3102Changes in 1.1.11 (2006-11-25):
3103
3104* Updated Czech, Spanish, and Slovak translations.
3105
[99d8798]3106* (MacOS X version): Assorted OS X specific tweaks and fixes.
3107
[920b066]3108* aven:
[78c67a6]3109
[920b066]3110  + Pick a smaller and clearer font for labels.
[99d8798]3111
[920b066]3112  + Fix character spacing.
[99d8798]3113
[920b066]3114  + Tweak display of bearing and elevation angles to look nicer with
3115    proportional fonts.
[99d8798]3116
[920b066]3117  + Use the title from the 3d (or plt, etc) file for the window title
3118    rather than the filename.
[99d8798]3119
[920b066]3120  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]3121
[920b066]3122  + Only consider underground legs when calculating the depth bands and
3123    depth colouring.
[99d8798]3124
[920b066]3125  + Add "Colour by Error".
[99d8798]3126
[920b066]3127  + Add entry for "white" in date and error keys.
[99d8798]3128
[920b066]3129  + When setting the view to a single point, don't change the scale.
[99d8798]3130
[920b066]3131  + If reloading the same file, don't change the view
[99d8798]3132
[920b066]3133  + Fix filetypes selector in open dialog.
[99d8798]3134
[920b066]3135  + Fix the charset we use for aven in certain cases.
[99d8798]3136
[920b066]3137  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]3138
[920b066]3139  + Pass wx the full language code to initialise the C library locale.
[99d8798]3140
[920b066]3141  + Fix bug in generating prefix tree view which could lead to a bogus
3142    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]3143
[920b066]3144  + "New Presentation" now ensures that the side panel is open
[99d8798]3145
[920b066]3146  + Fix updating of cached opengl lists when the view is reset to the
3147    default.
[99d8798]3148
[920b066]3149* Ignore LANG if it starts with a digit to avoid problems with bogus value for
3150  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]3151
[920b066]3152* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
3153  specified.  Either/both can be set to ":".
[99d8798]3154
[920b066]3155* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]3156
[920b066]3157* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]3158
[920b066]3159Changes in 1.1.10 (2006-07-14):
[ac3f376]3160
3161* aven: Clicking on a survey name in the survey tree now highlights it in
3162  the map view.  Double-clicking zooms the view to show the clicked survey
3163  highlighted.  Clicking the root clears the highlighting and double-clicking
3164  the root restores the default view.  To expand/collapse a branch, click
3165  on the "[+]" or "[-]" icon to the left of the survey name.
3166
3167* aven: The measuring line can now measure to anywhere in plan or elevation
3168  view (not just to a station!)  In plan view the horizontal distance and
3169  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]3170
[ac3f376]3171* aven: Moving the mouse over a station in the survey view now highlights
3172  that station in the survey tree (though it may not be visible if the
3173  survey(s) it is in aren't expanded).
3174
3175* aven: Clicking on a station to centre the view now moves the mouse pointer
3176  to the new location of the station (except on Mac OS X where this isn't
3177  allowed).
3178
3179* aven: Fix which presentation toolbar buttons are shown as depressed.
3180
3181* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
3182
3183* vim files are now installed with the correct paths (bug introduced in 1.1.9).
3184
[920b066]3185Changes in 1.1.9 (2006-07-04):
[6a2594be]3186
3187* (Unix version): Install desktop files for aven and svxedit contributed to the
3188  Ubuntu package by Phil Bull, and corresponding pixmaps.
3189
3190* Fix img to filter out cross-sections which don't match the subsurvey (if
3191  specified).  The API now returns img_XSECT_END to mark the end of a
3192  passage rather than setting a flag on the last img_XSECT of the passage.
3193
3194* Enhance integration with the vim editor - this can now colour .err files, run
3195  cavern from vim and parse error output, and run aven from vim.  Tweak the
3196  existing vim mode for .svx files to fix a few minor bugs and add support for
3197  the new "*data passage" style.
3198
3199* aven: fix drawing of the "blob" end of the measuring line on graphics cards
3200  which can't draw large enough blobs for us.
3201
3202* aven: sort out confusion about what encoding everything is in which means
3203  that the distance measured by the measuring line actually gets displayed
3204  and also fixes problems with empty menu items in non-English locales in
3205  some cases.
3206
3207* aven: redraw grey background after a menu is closed over the aven window
3208  with no survey loaded.
3209
3210* aven: fix bug which caused printing to crash (introduced in 1.1.8).
3211
3212* aven: avoid crash on some machines when opening "About" dialog before having
3213  loaded a survey.
3214
3215* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
3216
3217* (Unix version): aven: Fix character set handling of cavern output.
3218
3219* cavern: Report an error if a cross-section is specified for a station which
3220  doesn't exist.
3221
3222* Updated French and Italian translations.
3223
3224* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]3225  `${prefix}/share/survex'" error.
3226
[6a2594be]3227* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
3228  (doesn't affect Survex itself, but other applications which use img.c should
3229  update their copy).
3230
3231* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
3232  and later are caught by configure, whereas older wx versions are caught when
3233  trying to compile).
3234
[920b066]3235Changes in 1.1.8 (2006.06.30):
[cd39f67]3236
[c988ae4]3237* Drop support for building with wxWidgets versions prior to 2.4.0
3238  (which was released on 2003-01-07).
3239
[9577fcc]3240* aven: Printing through aven now uses settings from the "[aven]" section
3241  of print.ini, and support for hierarchical sections (using "like=")
3242  has been disabled.
3243
[ecf2d23]3244* aven: Change mouse actions to be compatible with those in Survex 1.0.
3245  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
3246  left drag is now smart about not rotating and zooming at the same
3247  time.
3248
[d1628e8e]3249* aven: Highlighting stations now happens as you type, and pressing
3250  "Enter" or clicking the "Find" button now pans and zooms to show the
3251  highlighted stations.
3252
[e67ed1b]3253* aven: Left-clicking away from a station now cancels measuring line.
3254
[3ddd351]3255* aven: Setting view to North, South, East, or West is now animated like
3256  the tilt from plan to elevation.
3257
[c988ae4]3258* aven: Fix presentation saving to also write "." for decimal points and
3259  presentation loading to accept either "." or ",".
3260
3261* (Unix version): aven: Add text for all toolbar items so that aven
3262  will work with the Gnome desktop preference for displaying toolbars as
3263  icons with text or just text (wxWidgets needs fixing first though).
3264
3265* (Unix version): aven: Remove the ability to detach the menu bar (yell
3266  if you actually used it and I'll restore it!)
3267
3268* aven: Add "all survey files" option to the "open file" dialog.
3269
[84f1ed1]3270* (MS Windows version): aven: Fix cursor keys to pan survey.
3271
[a884696]3272* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
3273
[9fe7af4f]3274* (MS Windows version): Fix installer to work on Windows 2000 or XP if
3275  run by an unprivileged user.
3276
3277* (MS Windows version): Upgrade to the latest version of InnoSetup (the
3278  installer builder we use) and include new installer translations for
3279  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
3280
3281* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
3282  translations of messages for wxWidgets (the GUI library we use).
3283
[cd39f67]3284* aven: Disable "Highlight exported points" if there aren't any.
3285
[afffec4]3286* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]3287  Italian, Catalan, Spanish, and Romanian translations.
[581624b]3288
[38a192d]3289* (Unix version): test suite: fix smoke test to pass even without X running
3290  (it was meant to but the code had a bug).
3291
[5892e08]3292* aven: Check if OpenGL is available and exit cleanly with a helpful error
3293  if it isn't.
3294
[879e9c3]3295* (Unix version): aven: Fix --help and --version to work without a working
3296  X display (provided it's built with wxWidgets 2.5.1 or newer).
3297
[c8f929b]3298* aven: Automatically select the presentation tab of the notebook when the user
3299  selects "New Presentation" or "Open Presentation".
3300
3301* aven: Fix "Delete" in the presentation list to not get passed on (and so not
3302  reset to default view as well).
3303
3304* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
3305  empty.
3306
3307* aven: Fix Cursor Up and Down in the presentation list to move the highlight
3308  up and down instead of being passed on and moving the survey.
3309
[9ad92cc]3310* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]3311  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
3312  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]3313
3314* aven: Put a 5mm border around exported SVG files to allow for station markers
3315  and non-zero width lines.
3316
3317* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
3318  was turned on.
3319
3320* aven: Actually close the file we're exporting which fixes problems with it
3321  not always being fully written.
3322
[920b066]3323Changes in 1.1.7 (2005.10.18):
[6662d02]3324
3325* cavern: Add validity checking for dates in *date commands (with feature
3326  test in testsuite).  A date entered as just "year" or "year.month" now
3327  becomes a date range for the relevant period (previously it became a single
3328  date near the middle of that period).
[e0c7cd1]3329
[8add4c9]3330* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
3331  with MS Windows).
3332
[9f524ee]3333* extend: Default output name for a file called input.3d is now input_extend.3d
3334  rather than just extend.3d (which was annoying if you wanted to extend
3335  several surveys in the same directory).
3336
[185d793]3337* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]3338  our check for them to include that knowledge.
[185d793]3339
[3515947]3340* aven: Regenerate depth bar if user switches to/from metric units.
3341
[1235f9b]3342* aven: Don't clear the "there" mark just because the mouse pointer has
3343  moved off a station.
3344
[4299674]3345* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]3346  same directory (since that's where we then try to load it from).
[4299674]3347
[60dbe70]3348* aven: Fix labelling of date colouring on 32 bit platforms.
3349
[125c9ea]3350* aven: If "colour by date" is on and we load a survey with no date info
3351  (or all surveyed on the same date) then set "colour by none".
3352
[ec58e3d3]3353* aven: Make the error dialog modal and remove a signal handler once it
3354  has fired to prevent endless (or seemingly endless) cascades of error
3355  dialogs.
3356
[8add4c9]3357* aven: Enforce a minimum object volume diameter of 1m to avoid problems
3358  if a survey file with only one station in is loaded.
3359
[6662d02]3360* aven: Fix problems with indicators disappearing when we're drawing
3361  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]3362  introduced in 1.1.6).
[6662d02]3363
[b65c13f]3364* (Unix version): aven: Really stop setting extra toolbar margin when using
3365  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3366  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3367
[17cce5f]3368* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3369  we've been compiled with, and which GTK+/Motif version where appropriate.
3370
[affaeee]3371* (Unix version): Fixed build on Fedora Core 3.
3372
[618b01f]3373* documentation: Updates to 3d file format specification from Mike McCombe.
3374
[920b066]3375Changes in 1.1.6 (2005.10.10):
[7e01c87]3376
3377* (MS Windows version): Distribution is about a third smaller than 1.1.5
3378  (mostly because mingwm10.dll is no longer required).
3379
[b88b171]3380* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3381  it, showing cavern's output in a window (with errors and warnings clickable
3382  to load the offending file into an editor), and then loading the resulting
3383  3d file.
3384
[7e01c87]3385* aven: Added "Colour by Date" option.
3386
3387* aven: Disable "Colour by Depth" option if there's no elevation variation.
3388
3389* aven: Don't crash if trying to load a survey with no elevation variation.
3390  Instead turn off depth colouring.
3391
[8ea82aa]3392* aven: Export as HPGL added.
3393
[887c26e]3394* aven: Improved update of mouse coordinates and measuring line (thanks to
3395  Martin Green).
3396
[7c29c976]3397* aven: Show the coordinates of either the mouse pointer or the nearest
3398  survey station to it (if there is one near enough).  Showing both was
3399  confusing and meant the status bar overflowed on smaller displays.
3400
[7e01c87]3401* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]3402
[7e01c87]3403* aven: Don't lock "flat" surveys which aren't extended elevations - a
3404  flat survey with LRUD data isn't flat any more!
3405
3406* aven: When we have to draw blobs and crosses the slow way (because the
3407  graphics hardware doesn't support the fast way), draw them so that they
3408  should appear at the correct depth into the 3D scene instead of on top
3409  of everything else.
3410
3411* aven: Make "play presentation backwards" icon green to match the other
3412  presentation icons.
3413
3414* (MS Windows version): aven: Mouse clicks on the survey view now set the
3415  keyboard focus there.
[bd21214]3416
[b46bf92]3417* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3418
[796d7bf]3419* (MS Windows version): aven: Fix redrawing of measuring line.
3420
[7e01c87]3421* cavern: Store dates for img_XSECT.
3422
3423* cavern: Fixed small one-off memory leak if you specify -o more than once.
3424
[b88b171]3425* (Unix version): Check environmental variable LC_MESSAGES when deciding what
3426  language to use for messages.
3427
[7c29c976]3428* (MS Windows version): "Print" on a 3d file now prints through aven rather
3429  than the separate printer driver (Unix has done this for some time).
3430
[8ea82aa]3431* Removed old printer drivers.
3432
[7e01c87]3433* img library: When creating a 3d file, ignore img_XSECT if we've been asked
3434  to write a file format version which doesn't support it.
[8ea82aa]3435
[920b066]3436Changes in 1.1.5 (2005.09.20):
[106cfdf]3437
3438* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3439
[4ba80e0]3440* aven: Make blobs round like they are in Survex 1.0.
3441
3442* aven: If the graphics drivers don't support drawing blobs using OpenGL
3443  point markers, fall back to drawing filled circles.
3444
[95ce35f]3445* aven: If the graphics drivers support it, draw crosses as texture mapped
3446  OpenGL point markers which is much faster.
[90d0d71]3447
[95ce35f]3448* aven: Cross size increased to match Survex 1.0.
3449
[cd78148]3450* aven: We must update which blobs are displayed if display of surface or
3451  underground legs is toggled.
3452
[f5627353]3453* cavern: Fix handling of a *solve followed by survey data, none of which is
3454  attached to the previous data.
3455
[dfe4a520]3456* cavern: Fixed "No survey data" error when a *solve is followed by another
3457  *solve (or the implicit solve at the end of processing) with no data between
3458  them.
3459
[920b066]3460Changes in 1.1.4 (2005.09.19):
[4855072]3461
3462* aven: Added Aven's icon to the "About" dialog.
3463
3464* aven: Use localised character for the decimal point (e.g. "," in most
3465  continental European countries).
3466
3467* aven: Previously the survey tree would get focus and then take keypresses
3468  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
3469  operate on the cave, and transfer the input focus across when we do.
3470
3471* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3472
3473* aven: Speed up intialisation by delaying creation of OpenGL lists until
3474  they're needed.
3475
3476* aven: Added Mark Shinwell's bounding box with shadow of the survey.
3477
3478* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3479
3480* aven: Reworded "Restore Default Settings" as "Restore Default View".
3481
3482* (Unix version): aven: Set sensible default margins for printing and preserve
3483  any margin values the user specifies between runs (previously margins
3484  defaulted to 0 each time aven was run).
3485
3486* Documentation: Document *DATA PASSAGE in the manual.
3487
[920b066]3488Changes in 1.1.3 (2005.09.07):
[0e558e5]3489
3490* (Microsoft Windows version): Fixed build problems.
3491
3492* cavern: Allow OMIT character (-) for left/right/up/down.
3493
3494* aven: Remove an unnecessary menu separator.
3495
3496* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3497
3498* aven: Make the tooltip for "Hide" show the number of found stations.
3499
3500* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3501
3502* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3503  when there's a presentation loaded.
3504
3505* aven: Make entrances green in side panel tree list to match green blobs used
3506  in cave view.
3507
3508* aven: Don't show surface labels if we're not showing surface data, etc.
3509
3510* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3511  make "Space" the key for this.  Keep Return working "Stop Rotation" so
3512  existing users are happy, but don't advertise it.
3513
3514* aven: Normalise filename by adding any extension used, and use the normalised
3515  filename for file history and window title.
3516
3517* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3518  as the toolbar buttons already have a sensible margin - the extra margin is
3519  only needed with GTK1.2.
3520
3521* aven: Fix handling of plumb legs in tube model.
3522
3523* aven: Fixed swapped L and R in tube model.
3524
3525* extend: Preserve UD cross-section information in extended elevation.
3526
3527* extend: Add new messages for John Pybus' enhancements.
3528
3529Changes in 1.1.2 (never formally released):
[8faa5d8]3530
3531* Added support for LRUD data in .svx files, in .3d files, and aven can
3532  now load and display it on screen and on printouts.  The ability to "fake"
3533  LRUD data in aven is gone for now but will reappear in some form later.
3534
3535* cavern: Removed support for writing Chasm's 3dx format.  We're going to
3536  fold any desirable missing chasm functionality into aven.
3537
3538* aven: Rearranged mouse actions as discussed on the mailing list.  Added
3539  cursors for each different mouse action to help the user learn what each
3540  does.  Also added cursors for the "compass" and "clino" as well as the
3541  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]3542
[0e558e5]3543* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]3544
3545* tests/smoketest.tst: If X windows is running, check that we can run aven
3546  with --help and --version.
3547
3548* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3549  no results are listed for it.  This revealed that there was a "newline" test
[6225339]3550  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]3551  Fixed all these problems.
3552
3553* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3554  and omitted forward compass/clino readings in Compass DAT files.  Added
3555  a feature test for this to the testsuite.
3556
3557* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]3558  without OpenGL so remove old machinery for this from configure and the
3559  sources.
[8faa5d8]3560
[0e558e5]3561* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]3562
3563* configure: Better output for strcasecmp test.
3564
3565* aven: Fix crosses to work much better.  Not a total fix - their position
3566  in the Z buffer isn't correct and they're rather slow to plot.
3567
3568* aven: Don't regenerate the hittest grid every time the mouse moves while
3569  animating, which solves the mysterious pausing effect (thanks go to Martin
3570  Green for spotting this!)  Also clear all the status bar coordinates when
3571  animating.
3572
3573* aven: Sort out clashing menu shortcuts in some languages.
3574
3575* aven: Fixed compilation problem on x86_64
3576
3577* SPUD: Pruned out stuff which has been done or which is not actually relevant
3578  to this branch.
3579
3580* Merge various changes from 1.0 branch:
3581
3582  + aven: Port over "printing from aven" functionality.
3583
3584  + aven: Port over "export as" functionality,
3585
3586  + Add David Loeffler's vim mode for .svx files.
3587
3588* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]3589
[8faa5d8]3590* aven: Don't use an opengl list for drawing the indicators - we typically make
3591  a new list each time we plot them anyway.
3592
3593* Remove lingering traces of support for RISC OS and pre-386 MSDOS
3594
3595* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]3596  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]3597
3598* configure: Update wxWindows checks to handle newer wx versions.
3599
3600* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3601  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
3602  for anyone building from CVS).
3603
3604* acinclude.m4: Quote macro name for fix autotools warning.
3605
[4855072]3606* Documentation: "tilt up" is "'" not ",".
[8faa5d8]3607
3608* aven: Add support for mousewheels (to tilt the cave).
3609
3610* aven: Fixed twisted transitions to and from pitches in certain cases.
3611
[0e558e5]3612* aven: Pick a sensible initial window size when the user's desktop is spread
3613  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]3614  better with wx2.4 or earlier as well).
3615
3616* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3617  contents being visible before any survey is loaded.
3618
3619* aven: Allow a coloured texture to be used
3620
3621* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]3622  is default colour (grey for most systems) not black until a survey is
3623  loaded).
[8faa5d8]3624
3625* aven: Fixed weird "shadowed" icons.
3626
[920b066]3627Changes in 1.1.1 (2004-10-06):
[a7aa27d9]3628
3629* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]3630  startup.
[a7aa27d9]3631
3632* aven: Delay loading the bitmap for the "About" dialog until it is first
3633  needed.  We want start up to be as quick as possible.
3634
[920b066]3635Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]3636
[91e416e]3637* NOTE: Survex 1.1.X releases are development snapshots made available for
3638  the purposes of allowing wider testing and getting more user feedback.  Once
3639  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]3640
[91e416e]3641* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3642  you're using Windows 95 - these can be obtained from:
3643  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]3644
[91e416e]3645* aven: Solid passages - passage dimensions are currently inferred from
3646  the leg length (pretty effective as you can measure longer legs in
3647  larger passages).  Use of real LRUD data coming soon...
[edb6576]3648
[91e416e]3649* aven: Depth colouring is now continuously varying.
[edb6576]3650
[0580c6a]3651* aven: Colour by depth can now be turned off (and there's the start of a
3652  framework for properly implementing colour by date, error, etc).
3653
[4261983]3654* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3655  match (? matches any character, * matches any number of characters).
3656
3657* aven: We now use the status bar for coordinates, distances, etc to make
3658  better use of screen space.
[edb6576]3659
[f80077a]3660* aven: Full screen mode (F11).
[edb6576]3661
[6abab84]3662* aven: Perspective view.
3663
[91e416e]3664* aven: Context sensitive cursor shape - needs more work.
[edb6576]3665
[91e416e]3666* aven: Mouse actions changed (hopefully they're now more natural, but
3667  you may find the change disorientating - feedback wanted on this).
[edb6576]3668
[1690fa9]3669* aven: Added "presentations" which allow you to set up fly-through paths
3670  and load/save/run them.
3671
[0580c6a]3672* aven: A presentation can be exported as a movie file.
3673
[045e2af]3674* aven: Added Save screenshot facility.
3675
[c60062d]3676* aven: Depth fogging option.
3677
[0580c6a]3678* aven: Added Smooth Lines option.
3679
3680* aven: Added Textured Walls option.
3681
[f433fda]3682* aven: If a survey has surface legs but no underground legs, default to
3683  showing the surface legs.
3684
[0580c6a]3685* cavern: Dates given to *date are now stored in the 3d file.
