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