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