[2d865b7]1Changes in 1.2.21 (2015-07-28):
[31e9b72]2
[03c259e]3* aven:
4
[2d865b7]5  + Fix exporting to KML and other text-based formats to always use "." for the
6    decimal separator - previously "," would be used when the user's locale
7    specified this for the decimal separator.  Reported by Jan Schorn.
8
[22f17f1]9  + Implement exporting of survey legs in KML format.
10
[03c259e]11  + Put "paddle" placemarker icons on stations in exported KML files, using the
12    same colour coding for entrances, fixed points and exported points as aven
13    does.
14
[2d865b7]15  + Remove the "Coordinate projection" field from the print dialog, as it isn't
16    relevant there.  Reported by Wookey.
17
18  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
19    been too small).  Reported by Wookey.
20
21  + Don't rescale if the same file is reloaded, but adjust the volume diameter
22    as appropriate.
23
[03c259e]24  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
25    values on Windows.
26
27* cavern:
28
[22f17f1]29  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
30    radians, but we were passing degrees, which would generally cause the
31    conversion to the output coordinate system to fail.  Reported by Wookey.
32
[2d865b7]33  + Fix *fix with standard deviations when *cs is in use, give an error for use
34    of *fix with standard deviations before *cs.
35
36  + Add new *declination command with support for setting the declination
37    automatically from the IGRF model based on the survey date.  Thanks to the
38    Therion developers for the IGRF support code, which we're reusing.
[1687a13]39    Fixes #54, reported by Wookey.
40
41  + Allow the units for the zero error to be specified, making it easier to
42    specify calibration with a scale if you measure the zero error externally
43    (rather than using the instrument itself).  Fixes #61, reported by Andrew
44    Atkinson.
[2d865b7]45
46  + Report the error from PROJ when coordinate conversion fails as part of the
47    actual error rather than on a separate line.
[22f17f1]48
[03c259e]49  + Fix use after free after *solve.  This only occurs if a leg between the two
50    exact same stations appears right before and right after the *solve, which
51    is unlikely in real data, but the testsuite has an instance of this.  This
52    was introduced by the repeat leg averaging added in 1.2.17.
53
54  + Fix small memory leak when solving network.  This doesn't really matter
55    when solving at the end of processing as cavern will exit after that, but
56    if *solve is used we continue processing after solving.
57
58* Remove compatibility handling for specifying a country variant of a language
59  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
60  changed to the standard "en_US" way back in 2001.  This code was mangling
61  character sets with a "-" in, and is no longer useful.
62
63* Ignore any "@<something>" modifier in the language code.
64
[2d865b7]65* Improve documentation of magnetic declination handling, and cover the new
66  "*DECLINATION" command.
67
[22f17f1]68* Remove references to SpeleoGen from the documentation - it hasn't been
69  updated for many years, and can't read recent versions of the .3d format.
70
71* Strip documentation references to obsolete versions of MS Windows.
72
[2d865b7]73* doc/HACKING.htm: Update list of debian packages to install to build from git.
74
[7027ea1]75Changes in 1.2.20 (2015-06-26):
[0eaf4b1]76
77* aven:
78
[6de8e942]79  + When printing, use the top margin rather than the right margin to calculate
[31e9b72]80    the height of the printable area.  In practice, the two values seem to be
81    the same or very similar by default.
[0eaf4b1]82
83  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
84    Maynard.
85
86  + Optimise the size of the about dialog images.
87
[7027ea1]88  + Add support for reading terrain data which isn't in a .zip file.
89
90  + Force a refresh after loading terrain data so that it gets displayed right
91    away.
92
93  + Make checks for terrain data extensions in zip files case insensitive.
[6de8e942]94
95  + If reading terrain data fails, always report an error and never try to
96    display it.
97
98* cavern: Allow clino readings in diving style data, suggested by Andrew
99  Atkinson.  Currently these readings are ignored, but a future version will
100  check that they're consistent with the angle given by the depth gauge and
101  tape, and perform suitable averaging.
102
[0eaf4b1]103* Remove lingering traces of svxedit.
104
105* configure: Fix to allow compiling without libav/ffmpeg, as was possible
106  before 1.2.19.
107
108* (Unix version): Install the filetype and aven application icons under
109  /usr/share/icons/hicolor, which is where they're expected to be these days.
110
111* (Unix version): Add %f to Exec in survex-aven.desktop.
112
113* (Mac OS X version): Remove useless extra copy of about box images from OS X
114  disk image.
115
[6de8e942]116* (Mac OS X version): Only ship one copy of each of the translations.
117
[0eaf4b1]118* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
119  libav features we don't use.
120
121* (Microsoft Windows version): Reduce the size of the aven binary by disabling
122  a load of libav features we don't use.
123
124* (Microsoft Windows version): Update message files to fix a missing Chinese
125  message in the installer.
126
[1dc99d1]127Changes in 1.2.19 (2015-06-18):
[f96ac93]128
129* aven:
130
131  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
132    the exported file in 1.2.18.
133
[2dac61e1]134  + Add exporting to Survex .pos format.
135
[4b67f71]136  + If the measuring line isn't currently active, pressing "Escape" will now
137    exit full screen mode.
138
139  + (Mac OS X version): Change the shortcut for full screen mode to be the
140    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
141    using since 1.2.7).
[2dac61e1]142
[f96ac93]143  + (Mac OS X version): When we centre the view on the station this can
144    generate a mouse move event, so clear the variable which says we are
145    dragging before we process a left click on a station.  This avoids random
146    rotations of the survey when clicking on a station, reported in #47 by Hugh
[2dac61e1]147    St. Lawrence.
[f96ac93]148
149  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
150    icons from being rescaled and looking fuzzy.
151
152  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
153    toolbar icons from being rescaled, but which requires an unreleased version
154    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
155
156  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
157    the top of the screen, since we can't seem to display the menu bar in this
158    case like we do on other platforms.
159
[739440f]160  + (Mac OS X version): Enable aven's movie export feature.
161
[2dac61e1]162  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
163    support multi-monitor setups.
164
[f96ac93]165  + (Mac OS X version): Silence warning visible when aven is run from a
166    terminal about a missing CFBundleTypeRole.
167
[4b67f71]168  + When reading terrain data from a .zip file, report an error if the .zip
169    file is bad, or if it doesn't contain any terrain data we recognise.
170
[f96ac93]171  + Tweak error message in terrain reading code to distinguish two failure
172    cases.
173
[2dac61e1]174  + Add viewing angles and scale to footer, and shorten some of the other items
175    to make room for this extra information.  (Fixes ticket #52, reported by
176    Erin Lynch)
177
178  + If the footer is wider than the printout width, scale down the font used
179    so that it exactly fits; if the footer is narrower, than space out the
180    items in in so it uses the full width.
[f96ac93]181
182  + If the saved size for aven's window exceeds the current display size
183    (mostly likely because we're now plugged into a smaller monitor), then
184    reduce the size of the window to fit the display.  If the saved size is <
185    (480x320), increase it to at least that, as aven isn't usable in a smaller
186    window.
187
[2dac61e1]188  + Remove crude bodge which tries to pick a nicer initial window size when
189    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
190    with the same size window it had when it was closed, so the initial size is
191    only relevant on the first ever run.
[f96ac93]192
193* Assorted translation updates.  Notably Indonesian is at 100% again.
194
195* Stop trying to catch and report signals.  The only real reason to do it is so
196  we can say "Bug in program detected! Please report this to the authors"
197  before we exit, but when the program crashes that's pretty obvious.  In aven
198  we try to pop up a message box for this message, which may fail due to
199  whatever caused the signal, while with the command line tools there's no
200  great benefit over just letting the shell report the signal.
201
[4b67f71]202* Use pkg-config to probe for libav and proj, which sorts out the correct flags
203  for building on OS X against a static install of libav.
204
[3f02aa4]205Changes in 1.2.18 (2015-06-03):
[2595419]206
[4a8031f]207* aven:
[a5670c7]208
[4a8031f]209  + Add support for reading terrain data (from a zip file containing either an
210    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
211    rendering it as a transparent surface.
[a5670c7]212
[4a8031f]213  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
214    sanely want to perform from the menu.
[a5670c7]215
[4a8031f]216  + Create a "Colour by" submenu of the "View" menu to house the various
217    colouring options.
[a5670c7]218
[4a8031f]219  + Add "Colour by Gradient" and "Colour by Length".
[a5670c7]220
[4a8031f]221  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
222    which seems more logical, and also allows the dialog to be closed by
223    pressing "Escape".
[a5670c7]224
[38e5701]225  + Destroy any existing clipping region before we write the page footer.
226    Hopefully solves ticket #52, reported by Erin Lynch.
227
[4a8031f]228  + Don't round bearing and tilt angles to integers when printing and
229    exporting.
[a5670c7]230
[38e5701]231  + Add passage export for EPS format.  (Partly addresses ticket #4)
232
233  + Add JSON export.  This should be regarded as experimental, and the format
234    is quite likely to change.
235
[4a8031f]236  + Pressing F6 now toggles the display of rendering stats, currently FPS
237    (Frames Per Second) and the number of triangles in the terrain mesh.
[a5670c7]238
[4a8031f]239  + Add a menu item and toolbar button to show the cavern log window if the
240    currently shown survey data was processed by aven.  Reported by Hugh St
241    Lawrence in #47, and by Dave Clucas and others previously on the list.
242
243  + Add "Save Log" button to Aven's cavern log window.
244
245  + In cavern log window, highlight "error" markers in red and "warning"
246    markers in orange.
247
248  + Rework code to read cavern's output.  In particular, we no longer mix
249    buffered and non-buffered system calls.
250
251  + Aven's support for reading colours and font sizes for printouts from
252    print.ini has never worked - the contents of the ini files are ignored due
253    to a bug which has been there since the code was added in 2005 - but nobody
254    has ever complained.  So just strip out that code entirely - we should
255    support setting the colours and font sizes, but a GUI interface for setting
256    them would be better.
257
258  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
259    Gee.
260
261  + Take the width of the messages used above the compass and clino into
262    account when calculating how much space to allow for them - now the labels
263    won't overlap or be cut off in translations where they are long.
264
265  + (Mac OS X version): Attempt to address the size of the toolbar icons.
266
267* cavern:
[0476b10]268
[38e5701]269  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
270    susscorfa).
271
[4a8031f]272  + Use the currently set units when outputting measurements in warnings,
[38e5701]273    errors, and the stats at the end of the run.  Requested by Bill Gee.
[4a8031f]274
275  + Include column number when a *include file isn't found.
276
277  + Show 'error' in front of error messages, like we show 'warning' in front of
278    warnings.  Fixes #48, reported by Wookey.
279
280  + Increase the threshold for warning that fore and back measurements differ
281    from 2 SDs to 3 SDs.
282
283* findentrances: If the 3d file specifies the coordinate system, use it.
284
285* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
286  would be nice to have, svxedit doesn't really offer that, and it looks ugly
287  in a modern desktop.
[a5670c7]288
[dd65182]289* If we run out of memory while reading a processed survey data file, include
290  the filename in the error message.
291
[4a8031f]292* Many translation updates - notably Indonesian and Russian are now the two
293  most complete translations.
[dd65182]294
[4a8031f]295* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
[dd65182]296
[4a8031f]297* Transliterate gradient and infinity symbols if the current character set
298  lacks them.
[dd65182]299
[4a8031f]300* Add SVG version of .plt icon.
301
302* Manual:
303
304  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
305    highlighting that the previous list was incomplete.
306
307  + Document averaging of a group of repeated readings.
[dd65182]308
[4a8031f]309  + Add a link to the sample data from the manual.
[dd65182]310
[4a8031f]311  + Remove references to contact addresses which are no longer there.  Remove
312    offer to post people floppies, and references to a CD image which isn't
313    available for download.
314
315* Remove non-breaking spaces from the diffpos and extend manual pages, as they
316  actually make the output formatting worse (presumably these used to work
317  around a since-fixed bug in one of the docbook processing tools).
[2595419]318
[4a8031f]319* doc/TODO.htm: Update.
[dd65182]320
[3f02aa4]321* Fix to compile without warnings with 'g++ --std=gnu++11'.
322
[1646310]323Changes in 1.2.17 (2015-02-24):
[a6064e2]324
325* MacOS X version:
326
327  + Update INSTALL file with current status.
328
[e067870]329  + Aven.app now has a custom icon.
[9e053fc]330
[e067870]331  + Add icons for all the filetypes supported.
332
333  + Add Finder actions for .svx, .3d, .plt and .pos files.
[9e053fc]334
335  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
336    currently do this for us.
337
[a6064e2]338  + aven: Fix short-cut for toggling Full Screen mode.
339
340  + aven: Make "About" menu item appear.
341
[9e053fc]342  + aven: Fix "Close" button in about dialog.
343
344  + aven: Make custom cursors black with a white outline to match the standard
345    OS X cursor.
346
[e067870]347  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
348    still doesn't really work like a standard app though - e.g. you can't load
349    files from Finder (instead run svxedit.app and use File->Open), the font
350    size of most menu items is wrong, the icon for the app is the wish icon
351    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
352    probably more.  I'd probably recommend using another editor (OS X comes
353    with TextEdit.app for example).
354
355  + The documentation is now in a "Docs" directory alongside the apps, rather
356    than in the rather less obvious "share/doc/survex" directory.
357
[a6064e2]358  + Default to building for x86_64, since all modern Macs are 64 bit.
359
[9e053fc]360  + Disable use of liblzma when building wxWidgets for OS X, which was
361    preventing the build from working on OS X 10.6.8.
362
363  + Download wx sources from SF via redirecting link.  Thanks to David A.
364    Riggs.
365
366  + buildmacosx.sh: Handle the mount point for the disk image containing a
367    space.
368
[4baea3a]369  + Link with a static build of PROJ for doing coordinate system conversions.
[9e053fc]370
371  + Build wx with --disable-webview to avoid a compilation failure on OS X
372    10.10.1.
373
374  + Use wx-config --cc and --cxx to get the compilers to use for building
375    everything else, as wx adds options to them which otherwise cause linking
376    errors.
377
[4baea3a]378  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
379    smaller download.  This means OS X 10.4 is required, but we probably
380    already need at least 10.5 because that's the minimum version which the
381    wxWidgets build supports by default.
382
[e067870]383  + Remove unused files and copies of files from the diskimage.
384
[a6064e2]385* cavern: If the same leg is repeated consecutively, average the readings and
386  treat as a single leg.
387
[9e053fc]388* dump3d: Report SEPARATOR used by the file being read.
389
390* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
391
392* aven:
393
394  + Greatly reduce flicker when mouse is moved to the top of the screen in full
395    screen mode and the menu bar reappears.
396
397  + For export formats where scaling is supporting, aven now actually uses the
398    scale specified in the export dialog (previously it ignored this and used
399    1:500).
400
401  + Reimplement animation so that it's based on angular change per unit of
402    elapsed time, rather than averaging the time take for the last two scene
403    redraws.  This gives smoother animation in the face of variable load and
404    scene redraw time, and should be more consistent between platforms.
405
406  + Switching to a point of the compass during auto-rotation now jumps straight
407    there rather than the two animations fighting.
408
409  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
410    fast.
411
412  + Disable stepping the rotation angle when animating (previously we only did
413    when rotating).
414
[1646310]415  + Speed up start-up a bit - rather than loading icons from individual PNG
416    files on disk, compile them into the aven binary.
417
418* (Unix version): Add "MimeType" field to desktop files so that file
419  associations work out of the box with modern desktop environments.
420
421* Add start of Hungarian translation from Imre Balogh.
422
423* Merge in many updates to the Russian translation from "vsuhachev".
424
425* Assorted minor updates to other translations.
426
427* Create scalable (SVG) versions of file type icons.
[e067870]428
[a6064e2]429* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
430  we're using git.
431
[1646310]432* tests/: Improve test coverage in a few places:
433
434  + Extend tests of fore and back sights to test calibration of the back
435    compass.
436
437  + Test "Can't calibrate angular and length quantities together" error.
438
439  + Check that "*set names ." works when "." is also the decimal point.
[a6064e2]440
[03d0e8b]441Changes in 1.2.16 (2014-10-17):
[9aa10ad]442
443* aven: Add KML export (stations only currently).
444
[f480117d]445* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
446
[9aa10ad]447* aven: Fix corrupted names in exported files.
448
449* aven: Fix error log window under wxWidgets >= 2.9 to include the system
450  information before the first log message like it does under wxWidgets 2.8.
451
452* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
453
454* tests/: Improve test coverage.
455
[7bd113b]456* Translation updates for many languages, plus the start of translations to
457  Greek and Polish.
[9aa10ad]458
459* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
460  by Martin Sluka.
461
462* Fix warnings when compiling with clang (which is the default compiler on
463  Mac OS X).  Reported by Martin Sluka.
464
[44f51ca]465Changes in 1.2.15 (2014-08-14):
466
467* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
468  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
469  means that we now support all the coordinates systems which Therion does,
470  except for a few which don't have X=East and Y=North.  The documentation
471  for *cs has also been improved.
472
473* aven: We no longer persist full screen mode between runs - it's not a
474  standard behaviour of desktop programs, and it's too easy to go into full
475  screen mode from the menu and then not be able to get out again because you
476  don't know the required key shortcut. (ticket#39)
477
478* aven: When in full screen mode, moving the mouse to the top of the screen now
479  makes the menu bar appear.  This provides a non-shortcut way out of full
480  screen mode, as well as making it easier to perform other operations while in
481  full screen mode.  The current implementation gives an annoyingly flickery
482  transition, but hopefully we can improve this in future. (ticket#39)
483
484* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
485  development), we now call EnableFullScreenView() which improves the full
486  screen mode experience on OS X 10.7 and later.
487
488* img library: Improve documentation for img_ERROR_INFO.
489
490* tests/: Ship some missing .out files and compare.tst.
491
492* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
493  testcase, and extend it to cover a variant of the situation reported as a bug
494  in therion by Bill Gee to the therion list.
495
496* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
497  for the survex package and on tk for the svxedit package.
498
[6a87cce]499Changes in 1.2.14 (2014-07-05):
[5c676e2]500
[1efeb6d]501* img library: Add ability to store a PROJ4 string describing the coordinate
502  system in use in 3d v8 files.
503
504* aven: If the 3d file specifies a coordinate system, then use it for exporting
505  to formats which need to know (currently GPX).  If the input file doesn't
[6a87cce]506  specify the coordinate system, allow the user to enter a PROJ4 string in the
507  export dialog.
[1efeb6d]508
[ea59b58]509* aven: You can now quickly zoom to a particular area by holding down the
510  "Shift" key and dragging with the left mouse button to create a rectangular
511  "rubber band box" around the area you wish to zoom to.  If you release the
512  "Shift" key while still dragging, the box is centred on the start point
513  rather than having one corner there.
514
[26e7fa4]515* aven: Fix exporting of passage tubes in elevations and extended elevations
516  - previously up and down were getting drawn across the page!
517
[5c676e2]518* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
519  1.2.13.  (Reported by Brian Clipstone)
520
[515b83e]521* aven: Fix the conditions on which the menu item "Cancel measuring line" is
522  enabled - previously it was hard to actually cancel it via the menu.
523  Reported by Hugh St Lawrence.
524
[5c676e2]525* aven: Fix wx assertion failures when showing hit test debug view on platforms
526  such as 64-bit Linux.
527
[2c5ec88]528* aven: When viewing from above, show "Plan" above the "clino" which indicates
529  the tilt angle (instead of "Elevation -90°").
530
[5c676e2]531* aven: The extended font data now loads faster, and also uses less memory on
532  64-bit platforms.
533
[ea59b58]534* aven: Dragging the vertical divider between the side panel and the 3D view
535  now only updates when you finish the drag, as redrawing continuously just
536  looks clunky except on an ultra-fast machine.
537
[2c5ec88]538* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
539  the space available in the aven UI.
540
[1efeb6d]541* cavern: Add a *cs command to allow setting the coordinate system for *fix
542  commands, and the coordinate system used for processed survey data.  The
543  latter is now stored in 3d v8 format files.
[ea59b58]544
[515b83e]545* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
546  and handle it in the same way as the "DUPLICATE" flag in .svx files.
547
[6a87cce]548* cavern: If there's more than one *fix command with coordinates, still
549  actually fix the second and subsequent ones, to avoid triggering bogus errors
550  about unconnected surveys.
551
552* cavern: If there's more than one *fix command with coordinates, report the
553  station name of the previous one, plus the file and line number where it was.
554
[67a0fc6]555* cavern: Fix handling of the rather contrived case of *fix with no coordinates
556  followed by *solve and then another *fix with no coordinates not to access
557  freed memory.
558
[1efeb6d]559* dump3d: Report any specified coordinate system.
560
561* doc/3dformat.htm: Update to document how the coordinate system is stored.
562
[2c5ec88]563* (Microsoft Windows version): Include dump3d in the installer.
564
[5c676e2]565* Fix a compiler warning.
566
567* Improve test coverage.
568
[0d365be]569Changes in 1.2.13 (2014-05-15):
[acbb5b1]570
[8ccd1d8]571* aven: Fix --print option to wait for printing to happen before exiting
572  (previously it would exit right after opening the print dialog, so you
573  couldn't actually print anything out using it).
574
[acbb5b1]575* aven: Increase the threshold for how close the pointer needs to be to a
576  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
577  Hugh St Lawrence.
578
[0d365be]579* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]580  if increasing the minimum pointer to station threshold helps Hugh's problems
581  with using aven on a touch screen device.
582
[acbb5b1]583* aven: The measuring line was unable to see stations which had just been
584  revealed by toggling surface or underground legs on - this is now fixed.
585
586* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
587  many entries are in each box (toggled by F3).
588
589* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
590  off and back on.
591
592* aven: Create the empty hit-test grid data structure lazily, to reduce start
593  up time a little.
594
595* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
596  and *end commands to instead talk about "survey names".
597
598* cavern: For ages cavern has warned if you reentered a survey, but this
599  warning was suppressed if it occurred at the same line of the same file as
600  the survey was first entered, but this can only happen if you include the
601  same survey file more than once, which isn't a sensible thing to do for a
602  file with actual survey data in (you might reasonably do it to set up survey
603  grade details or something like that).  The warning is now given in this
604  situation too.
605
606* cavern: After 5 warnings about reentering a survey we give up warning about
607  it, but we used to keep reporting where the survey was originally entered -
608  this secondary diagnostic message is now silenced when the main message is.
609
610* (Microsoft Windows version): Compile C code with optimisation on.
611
612* Add the start of a Russian translation, with messages take from therion.
613
614* Minor translation updates to French.
615
616* Fix compiler warning from GCC.
617
618* Testsuite improvements:
619
620  + Test that "..." anon station works.
621
622  + cavern.tst: Check number of errors returned by all testcases which should
623    fail and give an error count.
624
625  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
626
[ad727d8]627Changes in 1.2.12 (2014-04-14):
[46d12e9]628
[63e8642]629* aven: Fix measuring line to show change in altitude rather than altitude
630  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
631  Clipstone.
[46d12e9]632
[ad727d8]633* aven: Fix printing when built with wxWidgets 3.0.
634
635* aven: Several visual improvements to printouts:
636
637  + Move the numbers below the scale bar down a little so that they don't
638    overlap the scale bar ticks.
639
640  + Set the clipping region after we draw the page border and info box to avoid
641    clipping the border in print preview.
642
643  + Tidy up the appearance of the compass and elevation arrow.
644
[63e8642]645* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
646  <http://bugs.debian.org/739332>.
[46d12e9]647
[63e8642]648* aven: Fix to build with older libav where avcodec_free_frame() isn't
649  available.
[46d12e9]650
[ad727d8]651* (Linux version) survex.spec: Update spec file used for building RPM packages.
652
653* (Unix version): Add "Keywords:" entry to .desktop files.
654
655* (Unix version): Enable large file support, mostly to support filing systems
656  which return 64 bit inode values, such as CIFS mounts.
657
[63e8642]658* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
659  rather than any character which is a letter in the current locale.
[46d12e9]660
[63e8642]661* Various translation updates.
[46d12e9]662
[aac3336]663Changes in 1.2.11 (2014-01-28):
[fb941bfd]664
665* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
666  Reported by Kevin Dixon.
667
[aac3336]668* aven: Embed the font data for the first 256 Unicode characters for use in the
669  survey pane into the compiled aven binary to reduce start up overhead.  Any
670  additional characters needed are loaded from a data file only if/when a
671  character >= U+100 is actually needed (as before).
672
[ad3017d]673* aven: Fix display of Unicode characters above 256 when there's a character
674  <= 256 earlier in the same string.
675
[77bdacf]676* aven: Use the actual width of Unicode characters above 256 rather than
677  assuming they are 16 pixels wide.
[ad3017d]678
679* aven: If full screen, don't show the side panel when a new file is opened
680  (e.g. via Ctrl+O).
681
682* aven: Don't give an assertion failure when showing passages for a cave with
683  no vertical extent.  Reported by Jonny Prouty.
684
685* aven: Change terminology in print dialog - say "legend" instead of "info
686  box".
687
688* aven: Add option to show the tilt angle as a percentage gradient.
689
690* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
691  indicators.
692
693* aven: All length units are now translatable.
694
[fb941bfd]695* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
696  will reduce code size and also the number of deprecation warnings about
697  gluErrorString on Mac OS X 10.9.
698
[ad3017d]699* (Microsoft Windows version): aven: Try to work around redraw issues related
700  to the measuring line by redrawing the whole window, which doesn't seem to be
701  measurably slower.
702
703* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
704  give an error rather than quietly ignoring the attempt.
705
[77bdacf]706* cad3d: Make cad3d remap control characters and spaces in station names when
707  generating PLT output in the same way aven does.
708
[ad3017d]709* Various translation updates (particular thanks to Eric Madelaine and Dennis
710  Baudys), including the start of a Bulgarian translation, with messages taken
711  from Therion and elsewhere.
712
713* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
714  GetUserDefaultUILanguage() to get the UI language to use.  For older
715  versions, continue to use GetUserDefaultLCID().
[fb941bfd]716
717* (Microsoft Windows version): The Indonesian translation will now be used
718  automatically when the system language is set to Indonesian.
719
720* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
721  A. Riggs for his work on this.
722
723* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
724  checksum check for the downloaded wx sources.
725
726* Fix a lot of the compiler warnings when building with clang.
727
[ad3017d]728* doc/manual.sgml: Add missing quantities to the list documented as accepted by
729  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
730  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
731  mentioned in list of the units that can be set for them); COUNT (missing
732  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
733  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
734
735* Test suite: Improve test coverage for cavern.
736
[0ecf3b1]737Changes in 1.2.10 (2014-01-15):
738
739* aven: Fix assertion if two mouse buttons are held down at the same time.
740  If dragging with more than one mouse button held down, releasing one causes
741  another which is still held down to take effect.  Reported by Brian
742  Clipstone.
743
[53966d3]744* aven: If we fail to start the external editor when the user clicks on an
745  error or warning from cavern, show an error box.
746
[6f0d0d8]747* aven: If the survey has a title, add it as a top-level <title> element to
748  exported SVG files.
749
750* aven: Escape '<', '>', and '&' in labels in exported SVG files.
751
752* aven: In GPX export, set the <time> element to the datestamp from the 3d
753  file.
754
755* aven: Don't try to write the title if it isn't set or is empty when exporting
756  GPX files.
757
758* aven: Don't bother looking up the printer page setup info when exporting.
759
[0ecf3b1]760* (Microsoft Windows version): aven: Fix crash on "File->Print" or
761  "File->Export" under Windows XP, reported by Brian Clipstone.
762
763* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
764  encoded filename which could occur if run without being asked to load a file
765  on startup.
766
767* (Microsoft Windows version): aven: Compile with optimisation on.
768
769* img library, aven: Although processed CMAP data files are often referred to
770  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
771  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
772  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
773  continue to do so in case anyone is relying on it, but also check for the
774  other extensions.
775
776* img library: Add new "datestamp_numeric" field to struct img giving the
777  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
778  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
779  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
780  timezone wrong.
781
782* img library: Fix my_strcasecmp() to handle top-bit set characters better.
783
[6f0d0d8]784* cavern: Fix NULL pointer dereference when processing Compass DAT file without
785  'SURVEY DATE:'.
[0ecf3b1]786
[6f0d0d8]787* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]788
[6f0d0d8]789* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]790
[53966d3]791* Fix some compiler warnings if built with glibc's fortify source feature
792  enabled.
793
[6b6fb4d]794Changes in 1.2.9 (2014-01-08):
795
796* Document --3d-version in cavern man page and the manual.
797
798* aven: Fix compilation error in movie export code with recent libavi.
799
800* aven: Fix warning on stderr when export a movie as MPEG.
801
802* img library: In non-hosted mode, don't define GETC and PUTC if they're
803  already defined, to allow easy overriding with getc_unlocked() and
804  putc_unlocked() (which are significantly faster on Linux).
805
806* img library: In non-hosted mode, check that int is at least 32 bits,
807  and if not, use long.  In practice, platforms with 16 bit int are mostly
808  obsolete, but it's not hard to be portable here.
809
810* img library: Add test that img.c and img.h compile in non-hosted mode
811  (regression test for issue fixed in 1.2.8).
812
813* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
814
815* Update translations from launchpad and from existing similar messages.
816
817* Fix some compiler warnings.
818
[e1f27c4]819Changes in 1.2.8 (2013-10-29):
[da65891]820
821* cavern: Fix handling of anonymous wall stations ('..' by default) to
822  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
823  Holder.
824
[e1f27c4]825* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]826  statistics when the value gets large.
827
[a4adf09]828* cavern: Eliminate redundant progress message when solving simultaneous
829  equations.
830
[e1f27c4]831* aven: Add a format drop down to the export dialog, and only show fields which
832  are meaningful and supported for the currently selected export format.  The
833  format defaults to that used most recently.  The "Elements" and "View" boxes
834  have been swapped in the print and export dialogs as that layout works much
835  better when the "View" box is hidden.
836
[0056ee1]837* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
838  - now works again.  Reported by Anthony Day.
839
[e1f27c4]840* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
841  this release the projection which the survey coordinates are in defaults
842  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
843  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
844  projection string.  The ability to specify this projection in a better
845  way is coming soon.
846
847* aven: New export options "Origin in centre" and "Full coordinates" - the
848  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
849
850* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
851  time ago, so update references.
852
853* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
854  with wxMSW 2.9.5.  Reported by Brian Clipstone.
855
856* aven: Make right click in an empty presentation mark the current position and
857  open it to edit, instead of crashing.
858
859* aven: Update movie export code to work with latest libav API.  Reported by
860  Sebastian Ramacher.
861
862* aven: Improve reporting of errors during the process of exporting a movie.
863
864* aven: Don't try to close the movie if we aren't producing one.
865
866* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
867
868* aven: Fix to build with wxMSW 2.9.5.
869
870* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
871
872* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
873  ago, so add a new --skencil option to specify this output format.  The old
874  name (--sketch) is still recognised for compatibility.
875
876* cad3d: Make --marker-size work for Skencil and SVG output.
877
878* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]879
[88b54df6]880* img library:
881
[e1f27c4]882  + Fix to work once more when used outside of Survex (missing definition of
883    max() macro and a bad call to free() in img_close() for a file opened for
884    reading).
885
886  + Use lround() instead of round(), and make the tests around whether we use
887    the library function or the our fallback implementation saner.
888
889  + Fix // comments in C code for portability to pre-C99 compilers which don't
890    support these as an extension.
[88b54df6]891
[f807d8bf]892  + Can now be compiled as C++ as well as as C.
893
[e1f27c4]894* (Microsoft Windows version): The installer is now built with a newer version
895  of Innosetup, and includes translations for all the languages which Survex
896  itself has any translations for.
897
898* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
899
900* Minor translation updates.
901
902* tests/Makefile.am: Distribute files for "normal_bad" testcase.
903
[e34bebc]904Changes in 1.2.7 (2013-07-27):
[65d9b6b]905
[e34bebc]906* Add support for anonymous stations, which are indicated by one, two or three
907  separator characters - with the default separator of '.', that means '.',
908  '..', and '...' are anonymous stations.  Single separator ('.' by default)
909  is an anonymous non-wall point, double separator ('..' by default)
910  is an anoymous wall point at the end of an implicit splay), and triple
911  separator ('...' by default) is an anoymous point (with nothing special about
912  the leg).  A new *alias command allows '-' to be mapped to '..' for
913  compatibility with pocket topo: *alias station - ..
[07beaa4]914
[e34bebc]915* New version 8 of the 3d format:
[07beaa4]916
[e34bebc]917  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]918
[e34bebc]919  + New explicit file-wide flag for 'this is an extended elevation', rather
920    than modifying the survey title to indicate this.
[da9d788]921
[e34bebc]922  + The survey prefix is often unchanged from one leg to the next, so use a
923    spare flag to compactly indicate when there's no label change.
[da9d788]924
[e34bebc]925  + The data style of each leg is now stored.
[da9d788]926
[e34bebc]927  + The "processed at" time is stored as seconds since 1970 rather than a
928    human-readable string.
[da9d788]929
[e34bebc]930  + Since 3d v8 features significant changes to the format, the format
931    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]932
[e34bebc]933* img library:
[da9d788]934
[e34bebc]935  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]936
[e34bebc]937  + Handle .pos files containing unnamed stations - don't suck the next line in
938    as the station name, and set img_SFLAG_ANON for them.
[da9d788]939
[e34bebc]940  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
941    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
942    elevation, in place of appending " (extended)" to the title.  Internally we
943    still append this to the title (and remove it upon reading) when writing
944    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
945    explicitly in the file.
[da9d788]946
[e34bebc]947  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]948
[e34bebc]949* aven:
[da9d788]950
[e34bebc]951  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
952    now, and the wx developers consider even 2.8 to be rather long in the
953    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
954    formally dropping support for older versions allows a number of workarounds
955    to be removed from the aven source code.  Also, features deprecated in
956    wxWidgets 2.9 are no longer used in our code.
[da9d788]957
[e34bebc]958  + Don't run incremental search on every key-press, as on a slow machine the
959    short initial search(es) will take a while but not be useful.  Instead only
960    actually run the search when we're told there are no more key-presses
961    queued up.
[da9d788]962
[e34bebc]963  + Implement support for including cross-section information in exported SVG
964    and DXF files (ticket#4).  The DXF export is untested currently.
965
966  + Show splay legs faded by default, with menu options to hide them or show
967    them like other legs.
968
969  + Speed up loading a .3d file with cross-sections by using a map to convert
970    station names to positions.
971
972  + In the cavern log window, don't highlight a file:linenumber if there's no
973    message after it, which avoids highlighting the "Included from" lines
974    wrongly.
975
976  + Fix not to crash when trying to report an error while starting up.
977
978  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
979    the OS X standard shortcut Shift-Command-F (previously we used F11, but
980    that's used by the desktop).
981
982  + Add checks for errors when reading the font file.
[07beaa4]983
[e34bebc]984  + Remove useless extra quoting when invoking vim to show the location of an
985    error from cavern.
[07beaa4]986
[e34bebc]987  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]988
[e34bebc]989  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
990    in the dialog in sync.
[da9d788]991
[e34bebc]992* cavern:
[3dfffa2]993
[e34bebc]994  + Demote errors about invalid dates to warnings, since we've accepted *date
995    for ages without any checks on the value, and so existing datasets
996    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]997
[e34bebc]998  + New *alias command allows '-' to be mapped to '..' for compatibility with
999    pocket topo: *alias station - ..
[07beaa4]1000
[e34bebc]1001  + We want to warn if there's a clino reading which it would be impossible to
1002    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
1003    read "93" (it's probably a typo e.g. for "39").  However, the gradient
1004    reading from a topofil is typically in the range 0 to 180, with 90 being
1005    horizontal.  Really we should allow the valid range to be explicitly
1006    specified, but for now we infer it from the zero error - if this is within
1007    45 degrees of 90 then we assume the instrument can read between 0 and 180
1008    degrees.
[da9d788]1009
[e34bebc]1010  + If the survey isn't all connected, still run survey tree checks and report
1011    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
1012    Dixon for the report which highlighted this issue.
[da9d788]1013
[e34bebc]1014  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]1015
[e34bebc]1016  + Report column numbers as well as line numbers for some cavern errors and
1017    warnings.
[07beaa4]1018
[e34bebc]1019  + Adjust width of node stats table to fit longest count when there are more
1020    than 9999 of a particular order of node.
[07beaa4]1021
[e34bebc]1022  + If the argument to *include has an opening double quote but the closing
1023    double quote is missing, then skip trying to open the file.
[da9d788]1024
[e34bebc]1025  + Move "Station X referred to just once" warning after non-existent survey
1026    check - if both fire, the non-existent survey error is likely to be more
1027    relevant.
[da9d788]1028
[e34bebc]1029  + We no longer follow an error for a bad reading in passage data with a bogus
1030    "End of line not blank" error, but instead check the remaining readings on
1031    the same line.
[da9d788]1032
[e34bebc]1033  + We no longer follow an error about OMIT for a required reading with a bogus
1034    "End of line not blank" error.
[7f6250a]1035
[e34bebc]1036  + Report an error if the scale factor in *calibrate is zero - it doesn't make
1037    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]1038
[e34bebc]1039  + Report the parent include files starting from the outermost, as that's more
1040    logical when there are multiple levels involved.
[07beaa4]1041
[e34bebc]1042  + If we were expecting a numeric field and instead get something which starts
1043    with '+', '-', or '.' but which isn't a number, then fix the error to
1044    include that character in the token reported.
[3dfffa2]1045
[e34bebc]1046  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
1047    first item.
[07beaa4]1048
[e34bebc]1049* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]1050
[e34bebc]1051* dump3d:
[07beaa4]1052
[e34bebc]1053  + Build, install and package dump3d as standard - it's useful for grabbing
1054    info from 3d files in scripts.
[07beaa4]1055
[e34bebc]1056  + Add --show-dates option.
[07beaa4]1057
[e34bebc]1058  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]1059
[e34bebc]1060  + Report the data style of legs.
[da9d788]1061
[e34bebc]1062  + Report if the file is an extended elevation.
1063
1064  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]1065
1066* Test suite:
1067
1068  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
1069    expected output so it passes reliably.
1070
[e34bebc]1071  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
1072    'Deleted' stations upon failure are the more natural way round.
1073
[07beaa4]1074  + Add more testcases, expand some existing testcases, and add expected output
1075    for more.
1076
[e34bebc]1077* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
1078  appropriate C and C++ compilers to use, and link mingw build statically to
1079  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]1080
1081* (Unix version): When determining the character set for command-line tools,
1082  check environmental variable LANG after LC_ALL and LC_CTYPE.
1083
1084* When determining the language, check environmental variable LC_ALL before
1085  LC_MESSAGES and LANG (but after SURVEXLANG).
1086
[e34bebc]1087* If we don't find the message file, only give an error if it was specified
[665183c]1088  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]1089  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
1090  settings.
1091
1092* There are a handful of hard-coded English message strings for reporting
1093  errors trying loading message files, etc.  These are all now ASCII, as if we
1094  fail trying to open a message file, it's more likely the encoding isn't
1095  set correctly.
1096
1097* Prune strings we are no longer using and are probably unlikely to use again
1098  into a new file po_codes_dead, so that translators don't get presented with
1099  them to translate.
1100
[07beaa4]1101* Merge lots of translation updates.  Most translations are now complete or
1102  close to complete.
[3dfffa2]1103
1104* Add start of Indonesian translation from Arief Setiadi Wibowo.
1105
[07beaa4]1106* Fix various compiler warnings when building from source.
1107
[e34bebc]1108* Include scripts gdtconvert and gen_img2aven in the source distribution.
1109
[c575465]1110Changes in 1.2.6 (2012-02-23):
[b081031]1111
1112* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
1113
1114* (Microsoft Windows version): Include JPEG images for aven in the installer
1115  package (ticket#35).
1116
1117* cavern: If we have a reference to a station in a non-existent survey, give a
1118  helpful error rather than saying the station hasn't been exported from the
1119  survey.  (Bug reported by Martin Green via email)
1120
1121* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
1122  Kahler.
1123
1124* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]1125  .gpx file with waypoints for entrances.  This needs libproj so is disabled
1126  by default for this release - to enable it install the development stuff for
1127  libproj and build survex with:
1128
1129      make FINDENTRANCES=findentrances
1130      make install FINDENTRANCES=findentrances
[b081031]1131
1132* dump3d: Add support for showing img_ERROR_INFO items.
1133
1134* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
1135
1136* Incorporate a French translation from launchpad I'd previously copied the
1137  English version of by mistake.  Attempt to correct mistranslation of "survey
1138  file".
1139
[685116f]1140Changes in 1.2.5 (2012-01-03):
1141
1142* aven:
1143
1144  + The survey tree in the left panel is now in sorted order once more.
1145
1146  + No longer fails with an assertion if used for a long time (we were leaking
1147    an OpenGL list each time one had to be regenerated).
1148
1149  + Now builds with newer FFmpeg library.
1150
1151  + Draw measuring line in front of the indicators rather than behind them.
1152
1153  + Loading a new file (or reloading the current one) no longer invalidates
1154    the OpenGL lists for the compass and clino, so will be a fraction faster.
1155
1156* Improve handling of attempts to look up translated messages before the
1157  message subsystem is fully initialised (which only happens if there's an
1158  error early on).
1159
1160* Improve the survex(7) man page text, and fix it to be marked as section 7 in
1161  the man page source as well as in the filename.
1162
[f15ca67f]1163Changes in 1.2.4 (2012-01-01):
1164
1165* aven:
1166
1167  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
1168    initialised, which doesn't cause problems in some machines, but causes aven
1169    to abort on others.  This is now fixed, and there's a check in place to
1170    help avoid similar issues in future. (ticket#34)
1171
1172  + Always use metres or feet for the depth colour key, and chose a consistent
1173    precision by looking at the depth range. (ticket#30)
1174
1175  + Show the depth units below the colour bar rather than after every value.
1176
1177  + When zooming way in, stay in metres rather than switching to cm.
1178
1179  + On the scale bar, say “1 mile” rather than “1 miles”.
1180
1181* Translation updates for Catalan, French and Slovak.
1182
[5b9942e]1183Changes in 1.2.3 (2011-12-31):
1184
1185* Fix to build with wxWidgets 2.9.2.
1186
1187* (Mac OS X version):
1188
1189  + Processing .svx files from aven now works.
1190
1191  + Remove spurious blank lines from the licence text in "Get Info".
1192
1193  + Don't create the help menu at all, as it is empty (because the "About"
1194    entry goes elsewhere) and sometimes seems to appear in the UI.
1195
1196  + INSTALL.OSX: Update to reflect current status.
1197
1198* aven:
1199
1200  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
1201
1202  + Improvements to text plotted on the survey pane:
1203
1204    - Support plotting Unicode character points > 256 by lazily loading the
1205      data for them from the font file and plotting them with a direct call to
1206      glBitmap(), which is slower but doesn't require a display list per
1207      character.
1208
1209    - Adjust the spacing from fixed width to putting a one pixel gap either
1210      side of each one character (so two between adjacent glyphs).  Mostly this
1211      reduces the horizontal width, but it adds a pixel for characters like "m"
1212      and two in a few cases.
1213
1214    - Fix .pixelfont file generation to correctly handle characters wider than
1215      8 pixels.
1216
1217  + Fix expected cross shape so don't always reject using texture mapping to
1218    draw crosses.
1219
[3ea0178]1220  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
1221    as those consisting of just one.  Previously we would trip over the empty
1222    tube later.  Such tubes can for example be created by extend if a splay shot
1223    is the start or end of a tube.
1224
[5b9942e]1225  + Make the green colour used for entrances in the survey tree the same
1226    (slightly darker than before) green used for the entrance blobs.
1227
1228  + Report the version of the library we're actually running with if built
1229    against wx >= 2.9.2.  Make it clear that the version reported is the
1230    version *built* with for wx < 2.9.2.
1231
[3ea0178]1232* extend:
1233
1234  + Copy the end markers for passage tubes.
[5b9942e]1235
[3ea0178]1236  + Preserve left and right data for tubes (previously they were set to -1.0
1237    which means "no info").
1238
1239* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
1240  was no longer used - it certainly is!
1241
1242* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
1243  messages, and curly single right quote instead of straight ASCII apostrophe.
1244  Fall back to using straight ASCII versions if we can't represent them in the
1245  current character set.
[5b9942e]1246
[3ea0178]1247* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]1248
1249* Test suite:
1250
1251  + Add test coverage for interleaved diving data.
1252
1253  + Add testcase for diving data with topofil-style distance.
1254
[94960ad]1255Changes in 1.2.2 (2011-10-06):
1256
1257* aven:
1258
1259  + Replace the textured-mapped font drawing with an approach based on
1260    glBitmap.  This doesn't suffer from the character alignment issues which
1261    the textured-mapped fonts had, and is actually significantly faster on some
1262    machines.  The current font used is (mostly) fixed-width, but this isn't an
1263    inherent limitation - it was just the easiest font data to convert to a
1264    usable format.
1265
1266  + Fix assertion failure due to rounding differences on loading certain .3d
1267    files.  (ticket#26)
1268
1269  + Fix assertion failure when turning on 3D passages if they stick out higher
1270    or lower than any station.  (ticket#29)
1271
[53f8a93]1272  + Fix grid not to disappear when blobs are turned on and blobs are drawn
1273    using lines.
1274
[94960ad]1275  + If a degree sign isn't available in the character set in use, transliterate
1276    it to 'dg' rather than skipping it.
1277
1278  + Fix message which should have been a degree sign but got lost in the format
1279    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
1280    that bearings in the status bar now have a degree sign after them if they
1281    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
1282
1283  + Fix print dialog to calculate the scale required for "One page" right
1284    before it calculates how many pages are required, so we don't end up
1285    something other than 1x1 being shown when the user changes settings.
1286
1287  + Update the calculations for picking a scale and for deciding how many
1288    pages are needed to take into account the change in info box height made
1289    in 1.2.1.
1290
[9704252]1291Changes in 1.2.1 (2011-10-04):
[e3c58c3]1292
1293* Translation updates for US English.
1294
1295* aven:
1296
1297  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
1298    it now shows colours for dates and errors as well as depths.
1299
1300  + In the colour key for "colour by date", change "No info" to "Undated".
1301
1302  + Remove the dark grey background from the colour key and just put a single
1303    pixel black border around the colours.  This is more in keeping with the
1304    other controls, and means the colours are now on a black background so more
1305    visually similar to the survey legs.
1306
1307  + Move the colour key's "Undated"/"Not in loop" entry down a little to
1308    improve the appearance.  Make each section a pixel taller.
1309
[9704252]1310  + Allow "Colour by X" to be selected even if there's no data for X or only a
1311    single value of X used (the colour key is much smaller in these cases, and
1312    does still provide some useful information).
1313
1314  + Fix incorrect calculation of depth colouring for survey legs which straddle
1315    a depth band boundary.
[e3c58c3]1316
1317  + The scale bar, compass, clino, and colour key now all have right click
[9704252]1318    menus which allow related actions to be performed (especially handy in
1319    full-screen mode).
[e3c58c3]1320
1321  + Improve the font used on the survey pane - it now contains the '-'
1322    character (so the clino now shows negative angles as negative, and dates
1323    in the colour key are now hyphenated).  Also the spacing and alignment
1324    are a little better, though still not perfect.
1325
1326  + PLT file export now handles spaces and control characters in station names
1327    by escaping them with '%' as in URLs.
1328
1329  + Pressing "Enter" on a station in the tree control now centres the view on
1330    that station.
1331
1332  + The scale bar is now cached in an OpenGL display list since it often gets
1333    redrawn exactly the same - for example, when rotating, panning, etc.
1334
1335  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1336    then forces a refresh of the survey pane.  This is intended as a debugging
1337    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]1338    where a list should have been invalidated (please report if you find such
1339    a case as it is a bug).
[e3c58c3]1340
[9704252]1341  + We now automatically track which OpenGL display lists need to be
1342    invalidated on window width or height changes.
[e3c58c3]1343
1344  + Increase scale bar maximum width from 65% of the window width to 75% as it
1345    was in 1.0.x (except that if that would overlap the clino we now reduce
1346    that proportion down until it reaches 50%).  Make the limit of zooming in
1347    the same as in 1.0.x.  (ticket#23)
1348
[9704252]1349  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1350    the application was fullscreen (the dialog got opened under the main
1351    window!)  To work around this, aven would switch out of full screen mode
1352    temporarily while showing a dialog.  This case works properly with recent
1353    wxGTK, so disable our workaround with versions we know work.  Also, apply
1354    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1355    as there's no reason to think we need it for other platforms.
[e3c58c3]1356
1357  + Grey out the "View North" action when we're already viewing North, and
1358    similarly for other compass points.
1359
1360  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1361    info in the "About" dialog.
1362
1363  + Fix to set the correct filename on the root of the survey tree - previously
1364    the filename of the previous file loaded was used!
1365
1366  + The movie export code now works with newer versions of the FFmpeg libraries
1367    as well as still working with older versions.
1368
1369  + Fix mixed up messages - the print dialog now says "View" on the left
1370    subgroup of controls rather than some unrelated message.
1371
1372  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1373    field which gives the bearing and reduce the height on the info box by the
1374    removed field, so it's now 3cm for plans and elevations, as for extended
1375    elevations.  Report the tilt angle for tilted elevations which it seems has
1376    been missing for ages (it's not in recent 1.0.x either).
1377
1378  + Tweak the exact positioning of informational text on printouts to look
1379    nicer and make better use of the available space.
1380
1381  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1382    dialog.
1383
1384  + Make the sign of the tilt angle for printouts consistent with the sign
1385    shown by the "clino" in the survey pane.
1386
1387  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1388    and similarly for the "Elevation" button.
1389
[9704252]1390  + (Microsoft Windows version): Sort out appearance of custom cursors.
1391
[e3c58c3]1392  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1393
1394  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1395    you can't get out again easily, so add code to explicitly check for F11
1396    being pressed and toggle full screen.
1397
1398* (Linux version): Fix the RPM .spec file for where man pages now get installed
1399  and package aven.svg and the vim support files.  (Fixes from James Begley)
1400
1401* "make check" now performs several checks on the translation files.
1402
1403* More messages are now available to be translated.
1404
1405* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1406  the message handling changes in 1.2.0.
1407
1408* Fix warning when compiling with GCC.
1409
1410* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1411  sudo for installing on Unix.
1412
1413* In the manual, replace the instructions for building from source with a
1414  pointer to the clearer instructions in INSTALL.
1415
1416* In the manual, make it clear that installing with administrator rights
1417  also applies to newer platforms than XP.
1418
1419* doc/TODO.htm: Update.
1420
[120c1c6]1421Changes in 1.2.0 (2011-09-20):
[b4ac7007]1422
1423* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1424  English.
1425
[9cfcb3f]1426* tests/smoke.tst: aven no longer requires an X display for --help or
1427  --version, so replace skip of this check with a check that this remains the
1428  case.
1429
1430* We now use the standard .po and .pot file formats for storing translations
1431  (rather than the Survex-specific messages.txt format), and then translate
1432  these into Survex's .msg format.
1433
[b4ac7007]1434* (Unix version): Move survex man page to section 7 (since it isn't documenting
1435  an actual command).
1436
[9cfcb3f]1437* (Unix version): Write each generated man page to a temporary file, then
1438  atomically rename, to avoid leaving an empty or partial man page behind if
1439  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1440  recurrence of that).
1441
[b4ac7007]1442* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1443  than /usr/doc/survex.
1444
1445* aven:
1446
[120c1c6]1447  + Fix handling of accented characters in the survey pane.
1448
[9cfcb3f]1449  + Aven icon redrawn in SVG format - it's now a vector image which looks
1450    nicer at larger sizes.
1451
[b4ac7007]1452  + Explicitly request double-buffering, which seems to be needed for systems
1453    with GLX >= 1.3.
1454
1455  + Fix crash while trying to load certain .3d files.
1456
1457  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]1458    Currently this is disabled in Microsoft Windows builds, pending getting the
1459    required libraries set up for building releases.
[b4ac7007]1460
1461  + Reporting of errors during movie export improved.
1462
1463  + Force playback speed to "x1" during movie export.
1464
1465  + Use stock IDs for buttons where appropriate - such buttons may now be
1466    rendered with icons on some platforms.
1467
[9cfcb3f]1468  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1469    ISO8859-1).
1470
1471  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1472    as it's no longer required with modern versions.
1473
1474  + Don't redraw the survey on every mouse movement in the survey pane unless
1475    the measuring line is (or just was) active.  (ticket #17)
1476
[b4ac7007]1477* cavern:
1478
1479  + Drop "non-fatal" from the report of how many errors there were at the end
1480    of the run - it just confuses users - we won't even get here if there's a
1481    fatal error!
1482
[9cfcb3f]1483  + Add --3d-version option to allow the user to specify the version of the 3d
1484    format to output.  (ticket#21)
1485
1486* img library:
1487
1488  + Make the highest and lowest valid values for img_output_version available
1489    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1490
[b4ac7007]1491* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]1492  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]1493
[8f9b0b6d]1494Changes in 1.1.16 (2011-05-16):
[ecdb631]1495
1496* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1497  Portuguese, and US English.
1498
1499* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]1500  rather than '->' where these characters are available.
[ecdb631]1501
1502* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1503  GNU ld --as-needed (Debian bug #615781).
1504
1505* img.c:
1506
1507  + Fix code typo for IMG_API_VERSION == 0 case.
1508
1509  + Fix code typo in code used when IMG_HOSTED isn't defined.
1510
1511* doc/TODO.htm: Remove entries which have now been done.
1512
[8f9b0b6d]1513* (Microsoft Windows version): aven: We now include all the available
1514  translations for messages from wxWidgets, which means that standard widgets
1515  will appear translated where available even if Survex messages aren't
1516  translated.
1517
[f5e3521]1518Changes in 1.1.15 (2010-10-15):
[2d16e4e]1519
1520* aven:
1521
1522  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1523    follow terminology in manual and elsewhere.  Fixes ticket#15.
1524
1525  + When displaying output from cavern, don't update the window after every
1526    line, but only when we don't have data from cavern pending.  Hopefully
1527    addresses ticket#12.
1528
1529  + If we aren't using GL_POINTS for blobs, draw them using a series of
1530    abutting lines rather than with gluDisk which is faster and gives a
1531    consistent shape.
1532
1533  + Check whether blobs and crosses actually render correctly as points/point
1534    sprites, and if they don't, fall back to drawing them with lines.  The
1535    best method is cached on disk, and rechecked automatically if the graphics
1536    hardware is changed or the drivers upgraded.
1537
1538  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1539    though, so we still enable USE_FNT by default).
1540
1541  + Don't offer "All files" wildcard in presentation save dialog.
1542
1543  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1544    more places.
1545
1546  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1547    when running cavern from aven.  Fixes ticket#11.
1548
1549* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1550
1551* diffpos: Handle files with duplicate labels in better - extend generates
1552  duplicate labels when it breaks a loop.
1553
1554* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1555
1556* New v7 of .3d format which stores survey dates as number of days since
1557  January 1st 1900, so we now support dates from 1900-2078 (rather than
1558  1970-2037) with a smaller file size.  The img API is now versioned - you
1559  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1560  gives the survey dates in days in days1 and days2 instead of as time_t
1561  values in date1 and date2.  Fixes ticket#14.
1562
1563* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1564  former has been the canonical name for some time, with www.survex.com just
1565  redirecting to it.
1566
1567* (Unix version): Use unlocked file I/O if available, which can be much faster
1568  in some cases (we don't need the locking as we don't do multithreaded file
1569  I/O).
1570
1571* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1572  headers.
1573
1574* (Mac version): buildmacosx.sh now works again.
1575
1576* Most tests weren't actually running any testcases (looks like a sh
1577  portability issue).  This is now fixed, and fortunately all tests still pass.
1578
1579* Include the extra .isl translation files for Innosetup in the source archive.
1580
[f9473ab]1581Changes in 1.1.14 (2010-07-26):
1582
1583* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1584
1585* aven:
1586
1587  + After processing survey data, if there were warnings or errors, add a
1588    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1589    were only warnings, also add an "OK" button to allow moving on to viewing
1590    the processed survey data (fixes ticket#13).
1591
1592  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1593
1594  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1595    not the ': ' after), and to make the title for the terminal the
1596    warning/error message.  Avoid false positives by checking that '<line>' is
1597    a number.
1598
1599  + Don't double escape the contents of href and target in links in the cavern
1600    log window.
1601
1602  + Improve handling of the splitter window, fixing behavioural glitches in
1603    various cases.
1604
1605  + Highlight stations matching any current search when a file is loaded.
1606    (ticket#9)
1607
1608  + (Mac version): Fix build issue due to Mac OS X polluting the global
1609    namespace with its own "Point" class.
1610
1611  + (Unix version): The Gnome print dialog has its own preview window so
1612    suppress ours if using the Gnome one.
1613
1614  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1615
1616  + (Microsoft Windows version): Fix handling of a double-click on the survey
1617    tree when built with wxWidgets >= 2.8.11.
1618
1619* cavern: Report relevant file and line number for three warnings which didn't
1620  give them before.
1621
1622* (Unix and Mac versions): configure: Update the wx-config probing code -
1623  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1624  point looking for them now.
1625
1626* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1627  for easy installation.  Update it to work with the latest Survex versions
1628  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1629  private wxWidgets, use 2.8.11 not 2.7.0-1).
1630
1631* manual:
1632
1633  + Correctly capitalise "GTK".
1634
1635  + Note that on Linux we only regularly test builds with the GTK+ version
1636    (change taken from 1.0).
1637
1638* Fixed the cad3d man page, which was an empty file in 1.1.13.
1639
[0bd49eb]1640Changes in 1.1.13 (2010-06-16):
[90d0d71]1641
1642* Say "wxWidgets" instead of "wxWindows" consistently.
1643
[739b92c]1644* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1645
1646* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1647
1648* aven:
1649
[90d0d71]1650  + wxWidgets 2.6.0 or newer is now required.
1651
1652  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1653    work but hasn't been tested recently (all packaged versions of wxWidgets
1654    seem to be Unicode now).
1655
1656  + Fix potential uses of uninitialised variables which may have been causing
1657    occasional glitches when loading a file on start-up.
1658
[e4bfd2f]1659  + Improvements to the handling of the font used for plotting labels and other
1660    text on the survey pane:
1661
1662    - Loading the font file is more efficient.
1663
1664    - Character spacing is improved.
1665
1666    - Default font is now anti-aliased.
[90d0d71]1667
1668  + "About" dialog:
1669
1670    - Add "Copy" button to copy the system info to the clipboard for easier
1671      bug reporting.
1672
1673    - List OpenGL extensions last, since there are usually lots of them with a
1674      modern gfx card.
1675
1676    - Fix 100% CPU usage while the "About" dialog is open.
1677
1678  + Processing .svx files:
1679
1680    - Passing a .svx file on the command line now works better.
[1324d6c]1681
[739b92c]1682    - Put the survey data log window in a splitter in the usual frame rather
1683      than opening a separate frame for it.
1684
[90d0d71]1685    - Auto-scroll the log window until we've reported a warning or error.
1686
1687    - Fix small memory leak.
1688
1689  + The presentation filename now defaults to using the basename of the
1690    currently loaded dataset, but we always prompt before we first save with
1691    such a name.
1692
1693  + Reduce memory usage when saving a screenshot.
1694
[e4bfd2f]1695  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1696    persist the window size (and maximised or fullscreen state) between
1697    invocations.
1698
[90d0d71]1699  + Fix reporting of OpenGL errors.
1700
1701  + Fix glitches when tilting while looking East.
1702
[739b92c]1703  + Added Portuguese and Slovak translations of wxWidgets messages.
1704
[90d0d71]1705* Documentation:
1706
[e4bfd2f]1707  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1708
1709  + Drop the "alternative manual formats" self-extracting zip file - people
1710    will generally just want one of the formats, so downloading several
1711    together isn't very useful.
1712
[90d0d71]1713  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1714
1715  + GPL.htm: Replace HTML version of licence with a link to the version on
1716    the FSF website.
1717
1718  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1719    low level to be of interest to non-developers, and developers can look at
1720    the source code.
1721
1722* (Unix version): configure: New preferred name for specifying wx-config script
1723  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1724
[e4bfd2f]1725* (Linux version): Source RPM package dropped as you can just build an RPM
1726  package from the source tarball.
1727
[739b92c]1728* (Microsoft Windows version): The installer is now created with a newer
1729  version of InnoSetup, which gives a 10% smaller download.
1730
[2e12f8c]1731Changes in 1.1.12 (2007-02-07):
[5940815]1732
1733* aven:
1734
[3db0798]1735  + Remember the window size or maximised/fullscreen state between invocations.
1736
[5940815]1737  + Add options dialog to "Export" similar to the one for "Print".
1738
[6b2113d]1739  + The "number of pages required" in the print dialog now updates when you
1740    change what is to be shown (underground legs/surface legs/station
1741    names/crosses).
1742
[920b066]1743Changes in 1.1.11 (2006-11-25):
1744
1745* Updated Czech, Spanish, and Slovak translations.
1746
[99d8798]1747* (MacOS X version): Assorted OS X specific tweaks and fixes.
1748
[920b066]1749* aven:
[78c67a6]1750
[920b066]1751  + Pick a smaller and clearer font for labels.
[99d8798]1752
[920b066]1753  + Fix character spacing.
[99d8798]1754
[920b066]1755  + Tweak display of bearing and elevation angles to look nicer with
1756    proportional fonts.
[99d8798]1757
[920b066]1758  + Use the title from the 3d (or plt, etc) file for the window title
1759    rather than the filename.
[99d8798]1760
[920b066]1761  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1762
[920b066]1763  + Only consider underground legs when calculating the depth bands and
1764    depth colouring.
[99d8798]1765
[920b066]1766  + Add "Colour by Error".
[99d8798]1767
[920b066]1768  + Add entry for "white" in date and error keys.
[99d8798]1769
[920b066]1770  + When setting the view to a single point, don't change the scale.
[99d8798]1771
[920b066]1772  + If reloading the same file, don't change the view
[99d8798]1773
[920b066]1774  + Fix filetypes selector in open dialog.
[99d8798]1775
[920b066]1776  + Fix the charset we use for aven in certain cases.
[99d8798]1777
[920b066]1778  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1779
[920b066]1780  + Pass wx the full language code to initialise the C library locale.
[99d8798]1781
[920b066]1782  + Fix bug in generating prefix tree view which could lead to a bogus
1783    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1784
[920b066]1785  + "New Presentation" now ensures that the side panel is open
[99d8798]1786
[920b066]1787  + Fix updating of cached opengl lists when the view is reset to the
1788    default.
[99d8798]1789
[920b066]1790* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1791  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1792
[920b066]1793* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1794  specified.  Either/both can be set to ":".
[99d8798]1795
[920b066]1796* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1797
[920b066]1798* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1799
[920b066]1800Changes in 1.1.10 (2006-07-14):
[ac3f376]1801
1802* aven: Clicking on a survey name in the survey tree now highlights it in
1803  the map view.  Double-clicking zooms the view to show the clicked survey
1804  highlighted.  Clicking the root clears the highlighting and double-clicking
1805  the root restores the default view.  To expand/collapse a branch, click
1806  on the "[+]" or "[-]" icon to the left of the survey name.
1807
1808* aven: The measuring line can now measure to anywhere in plan or elevation
1809  view (not just to a station!)  In plan view the horizontal distance and
1810  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1811
[ac3f376]1812* aven: Moving the mouse over a station in the survey view now highlights
1813  that station in the survey tree (though it may not be visible if the
1814  survey(s) it is in aren't expanded).
1815
1816* aven: Clicking on a station to centre the view now moves the mouse pointer
1817  to the new location of the station (except on Mac OS X where this isn't
1818  allowed).
1819
1820* aven: Fix which presentation toolbar buttons are shown as depressed.
1821
1822* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1823
1824* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1825
[920b066]1826Changes in 1.1.9 (2006-07-04):
[6a2594be]1827
1828* (Unix version): Install desktop files for aven and svxedit contributed to the
1829  Ubuntu package by Phil Bull, and corresponding pixmaps.
1830
1831* Fix img to filter out cross-sections which don't match the subsurvey (if
1832  specified).  The API now returns img_XSECT_END to mark the end of a
1833  passage rather than setting a flag on the last img_XSECT of the passage.
1834
1835* Enhance integration with the vim editor - this can now colour .err files, run
1836  cavern from vim and parse error output, and run aven from vim.  Tweak the
1837  existing vim mode for .svx files to fix a few minor bugs and add support for
1838  the new "*data passage" style.
1839
1840* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1841  which can't draw large enough blobs for us.
1842
1843* aven: sort out confusion about what encoding everything is in which means
1844  that the distance measured by the measuring line actually gets displayed
1845  and also fixes problems with empty menu items in non-English locales in
1846  some cases.
1847
1848* aven: redraw grey background after a menu is closed over the aven window
1849  with no survey loaded.
1850
1851* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1852
1853* aven: avoid crash on some machines when opening "About" dialog before having
1854  loaded a survey.
1855
1856* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1857
1858* (Unix version): aven: Fix character set handling of cavern output.
1859
1860* cavern: Report an error if a cross-section is specified for a station which
1861  doesn't exist.
1862
1863* Updated French and Italian translations.
1864
1865* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1866  `${prefix}/share/survex'" error.
1867
[6a2594be]1868* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1869  (doesn't affect Survex itself, but other applications which use img.c should
1870  update their copy).
1871
1872* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1873  and later are caught by configure, whereas older wx versions are caught when
1874  trying to compile).
1875
[920b066]1876Changes in 1.1.8 (2006.06.30):
[cd39f67]1877
[c988ae4]1878* Drop support for building with wxWidgets versions prior to 2.4.0
1879  (which was released on 2003-01-07).
1880
[9577fcc]1881* aven: Printing through aven now uses settings from the "[aven]" section
1882  of print.ini, and support for hierarchical sections (using "like=")
1883  has been disabled.
1884
[ecf2d23]1885* aven: Change mouse actions to be compatible with those in Survex 1.0.
1886  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1887  left drag is now smart about not rotating and zooming at the same
1888  time.
1889
[d1628e8e]1890* aven: Highlighting stations now happens as you type, and pressing
1891  "Enter" or clicking the "Find" button now pans and zooms to show the
1892  highlighted stations.
1893
[e67ed1b]1894* aven: Left-clicking away from a station now cancels measuring line.
1895
[3ddd351]1896* aven: Setting view to North, South, East, or West is now animated like
1897  the tilt from plan to elevation.
1898
[c988ae4]1899* aven: Fix presentation saving to also write "." for decimal points and
1900  presentation loading to accept either "." or ",".
1901
1902* (Unix version): aven: Add text for all toolbar items so that aven
1903  will work with the Gnome desktop preference for displaying toolbars as
1904  icons with text or just text (wxWidgets needs fixing first though).
1905
1906* (Unix version): aven: Remove the ability to detach the menu bar (yell
1907  if you actually used it and I'll restore it!)
1908
1909* aven: Add "all survey files" option to the "open file" dialog.
1910
[84f1ed1]1911* (MS Windows version): aven: Fix cursor keys to pan survey.
1912
[a884696]1913* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1914
[9fe7af4f]1915* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1916  run by an unprivileged user.
1917
1918* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1919  installer builder we use) and include new installer translations for
1920  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1921
1922* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1923  translations of messages for wxWidgets (the GUI library we use).
1924
[cd39f67]1925* aven: Disable "Highlight exported points" if there aren't any.
1926
[afffec4]1927* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1928  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1929
[38a192d]1930* (Unix version): test suite: fix smoke test to pass even without X running
1931  (it was meant to but the code had a bug).
1932
[5892e08]1933* aven: Check if OpenGL is available and exit cleanly with a helpful error
1934  if it isn't.
1935
[879e9c3]1936* (Unix version): aven: Fix --help and --version to work without a working
1937  X display (provided it's built with wxWidgets 2.5.1 or newer).
1938
[c8f929b]1939* aven: Automatically select the presentation tab of the notebook when the user
1940  selects "New Presentation" or "Open Presentation".
1941
1942* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1943  reset to default view as well).
1944
1945* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1946  empty.
1947
1948* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1949  up and down instead of being passed on and moving the survey.
1950
[9ad92cc]1951* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1952  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1953  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1954
1955* aven: Put a 5mm border around exported SVG files to allow for station markers
1956  and non-zero width lines.
1957
1958* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1959  was turned on.
1960
1961* aven: Actually close the file we're exporting which fixes problems with it
1962  not always being fully written.
1963
[920b066]1964Changes in 1.1.7 (2005.10.18):
[6662d02]1965
1966* cavern: Add validity checking for dates in *date commands (with feature
1967  test in testsuite).  A date entered as just "year" or "year.month" now
1968  becomes a date range for the relevant period (previously it became a single
1969  date near the middle of that period).
[e0c7cd1]1970
[8add4c9]1971* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1972  with MS Windows).
1973
[9f524ee]1974* extend: Default output name for a file called input.3d is now input_extend.3d
1975  rather than just extend.3d (which was annoying if you wanted to extend
1976  several surveys in the same directory).
1977
[185d793]1978* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1979  our check for them to include that knowledge.
[185d793]1980
[3515947]1981* aven: Regenerate depth bar if user switches to/from metric units.
1982
[1235f9b]1983* aven: Don't clear the "there" mark just because the mouse pointer has
1984  moved off a station.
1985
[4299674]1986* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1987  same directory (since that's where we then try to load it from).
[4299674]1988
[60dbe70]1989* aven: Fix labelling of date colouring on 32 bit platforms.
1990
[125c9ea]1991* aven: If "colour by date" is on and we load a survey with no date info
1992  (or all surveyed on the same date) then set "colour by none".
1993
[ec58e3d3]1994* aven: Make the error dialog modal and remove a signal handler once it
1995  has fired to prevent endless (or seemingly endless) cascades of error
1996  dialogs.
1997
[8add4c9]1998* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1999  if a survey file with only one station in is loaded.
2000
[6662d02]2001* aven: Fix problems with indicators disappearing when we're drawing
2002  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]2003  introduced in 1.1.6).
[6662d02]2004
[b65c13f]2005* (Unix version): aven: Really stop setting extra toolbar margin when using
2006  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
2007  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
2008
[17cce5f]2009* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
2010  we've been compiled with, and which GTK+/Motif version where appropriate.
2011
[affaeee]2012* (Unix version): Fixed build on Fedora Core 3.
2013
[618b01f]2014* documentation: Updates to 3d file format specification from Mike McCombe.
2015
[920b066]2016Changes in 1.1.6 (2005.10.10):
[7e01c87]2017
2018* (MS Windows version): Distribution is about a third smaller than 1.1.5
2019  (mostly because mingwm10.dll is no longer required).
2020
[b88b171]2021* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
2022  it, showing cavern's output in a window (with errors and warnings clickable
2023  to load the offending file into an editor), and then loading the resulting
2024  3d file.
2025
[7e01c87]2026* aven: Added "Colour by Date" option.
2027
2028* aven: Disable "Colour by Depth" option if there's no elevation variation.
2029
2030* aven: Don't crash if trying to load a survey with no elevation variation.
2031  Instead turn off depth colouring.
2032
[8ea82aa]2033* aven: Export as HPGL added.
2034
[887c26e]2035* aven: Improved update of mouse coordinates and measuring line (thanks to
2036  Martin Green).
2037
[7c29c976]2038* aven: Show the coordinates of either the mouse pointer or the nearest
2039  survey station to it (if there is one near enough).  Showing both was
2040  confusing and meant the status bar overflowed on smaller displays.
2041
[7e01c87]2042* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]2043
[7e01c87]2044* aven: Don't lock "flat" surveys which aren't extended elevations - a
2045  flat survey with LRUD data isn't flat any more!
2046
2047* aven: When we have to draw blobs and crosses the slow way (because the
2048  graphics hardware doesn't support the fast way), draw them so that they
2049  should appear at the correct depth into the 3D scene instead of on top
2050  of everything else.
2051
2052* aven: Make "play presentation backwards" icon green to match the other
2053  presentation icons.
2054
2055* (MS Windows version): aven: Mouse clicks on the survey view now set the
2056  keyboard focus there.
[bd21214]2057
[b46bf92]2058* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
2059
[796d7bf]2060* (MS Windows version): aven: Fix redrawing of measuring line.
2061
[7e01c87]2062* cavern: Store dates for img_XSECT.
2063
2064* cavern: Fixed small one-off memory leak if you specify -o more than once.
2065
[b88b171]2066* (Unix version): Check environmental variable LC_MESSAGES when deciding what
2067  language to use for messages.
2068
[7c29c976]2069* (MS Windows version): "Print" on a 3d file now prints through aven rather
2070  than the separate printer driver (Unix has done this for some time).
2071
[8ea82aa]2072* Removed old printer drivers.
2073
[7e01c87]2074* img library: When creating a 3d file, ignore img_XSECT if we've been asked
2075  to write a file format version which doesn't support it.
[8ea82aa]2076
[920b066]2077Changes in 1.1.5 (2005.09.20):
[106cfdf]2078
2079* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
2080
[4ba80e0]2081* aven: Make blobs round like they are in Survex 1.0.
2082
2083* aven: If the graphics drivers don't support drawing blobs using OpenGL
2084  point markers, fall back to drawing filled circles.
2085
[95ce35f]2086* aven: If the graphics drivers support it, draw crosses as texture mapped
2087  OpenGL point markers which is much faster.
[90d0d71]2088
[95ce35f]2089* aven: Cross size increased to match Survex 1.0.
2090
[cd78148]2091* aven: We must update which blobs are displayed if display of surface or
2092  underground legs is toggled.
2093
[f5627353]2094* cavern: Fix handling of a *solve followed by survey data, none of which is
2095  attached to the previous data.
2096
[dfe4a520]2097* cavern: Fixed "No survey data" error when a *solve is followed by another
2098  *solve (or the implicit solve at the end of processing) with no data between
2099  them.
2100
[920b066]2101Changes in 1.1.4 (2005.09.19):
[4855072]2102
2103* aven: Added Aven's icon to the "About" dialog.
2104
2105* aven: Use localised character for the decimal point (e.g. "," in most
2106  continental European countries).
2107
2108* aven: Previously the survey tree would get focus and then take keypresses
2109  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
2110  operate on the cave, and transfer the input focus across when we do.
2111
2112* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
2113
2114* aven: Speed up intialisation by delaying creation of OpenGL lists until
2115  they're needed.
2116
2117* aven: Added Mark Shinwell's bounding box with shadow of the survey.
2118
2119* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
2120
2121* aven: Reworded "Restore Default Settings" as "Restore Default View".
2122
2123* (Unix version): aven: Set sensible default margins for printing and preserve
2124  any margin values the user specifies between runs (previously margins
2125  defaulted to 0 each time aven was run).
2126
2127* Documentation: Document *DATA PASSAGE in the manual.
2128
[920b066]2129Changes in 1.1.3 (2005.09.07):
[0e558e5]2130
2131* (Microsoft Windows version): Fixed build problems.
2132
2133* cavern: Allow OMIT character (-) for left/right/up/down.
2134
2135* aven: Remove an unnecessary menu separator.
2136
2137* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
2138
2139* aven: Make the tooltip for "Hide" show the number of found stations.
2140
2141* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
2142
2143* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
2144  when there's a presentation loaded.
2145
2146* aven: Make entrances green in side panel tree list to match green blobs used
2147  in cave view.
2148
2149* aven: Don't show surface labels if we're not showing surface data, etc.
2150
2151* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
2152  make "Space" the key for this.  Keep Return working "Stop Rotation" so
2153  existing users are happy, but don't advertise it.
2154
2155* aven: Normalise filename by adding any extension used, and use the normalised
2156  filename for file history and window title.
2157
2158* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
2159  as the toolbar buttons already have a sensible margin - the extra margin is
2160  only needed with GTK1.2.
2161
2162* aven: Fix handling of plumb legs in tube model.
2163
2164* aven: Fixed swapped L and R in tube model.
2165
2166* extend: Preserve UD cross-section information in extended elevation.
2167
2168* extend: Add new messages for John Pybus' enhancements.
2169
2170Changes in 1.1.2 (never formally released):
[8faa5d8]2171
2172* Added support for LRUD data in .svx files, in .3d files, and aven can
2173  now load and display it on screen and on printouts.  The ability to "fake"
2174  LRUD data in aven is gone for now but will reappear in some form later.
2175
2176* cavern: Removed support for writing Chasm's 3dx format.  We're going to
2177  fold any desirable missing chasm functionality into aven.
2178
2179* aven: Rearranged mouse actions as discussed on the mailing list.  Added
2180  cursors for each different mouse action to help the user learn what each
2181  does.  Also added cursors for the "compass" and "clino" as well as the
2182  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]2183
[0e558e5]2184* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]2185
2186* tests/smoketest.tst: If X windows is running, check that we can run aven
2187  with --help and --version.
2188
2189* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
2190  no results are listed for it.  This revealed that there was a "newline" test
[6225339]2191  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]2192  Fixed all these problems.
2193
2194* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
2195  and omitted forward compass/clino readings in Compass DAT files.  Added
2196  a feature test for this to the testsuite.
2197
2198* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]2199  without OpenGL so remove old machinery for this from configure and the
2200  sources.
[8faa5d8]2201
[0e558e5]2202* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]2203
2204* configure: Better output for strcasecmp test.
2205
2206* aven: Fix crosses to work much better.  Not a total fix - their position
2207  in the Z buffer isn't correct and they're rather slow to plot.
2208
2209* aven: Don't regenerate the hittest grid every time the mouse moves while
2210  animating, which solves the mysterious pausing effect (thanks go to Martin
2211  Green for spotting this!)  Also clear all the status bar coordinates when
2212  animating.
2213
2214* aven: Sort out clashing menu shortcuts in some languages.
2215
2216* aven: Fixed compilation problem on x86_64
2217
2218* SPUD: Pruned out stuff which has been done or which is not actually relevant
2219  to this branch.
2220
2221* Merge various changes from 1.0 branch:
2222
2223  + aven: Port over "printing from aven" functionality.
2224
2225  + aven: Port over "export as" functionality,
2226
2227  + Add David Loeffler's vim mode for .svx files.
2228
2229* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]2230
[8faa5d8]2231* aven: Don't use an opengl list for drawing the indicators - we typically make
2232  a new list each time we plot them anyway.
2233
2234* Remove lingering traces of support for RISC OS and pre-386 MSDOS
2235
2236* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]2237  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]2238
2239* configure: Update wxWindows checks to handle newer wx versions.
2240
2241* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
2242  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
2243  for anyone building from CVS).
2244
2245* acinclude.m4: Quote macro name for fix autotools warning.
2246
[4855072]2247* Documentation: "tilt up" is "'" not ",".
[8faa5d8]2248
2249* aven: Add support for mousewheels (to tilt the cave).
2250
2251* aven: Fixed twisted transitions to and from pitches in certain cases.
2252
[0e558e5]2253* aven: Pick a sensible initial window size when the user's desktop is spread
2254  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]2255  better with wx2.4 or earlier as well).
2256
2257* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
2258  contents being visible before any survey is loaded.
2259
2260* aven: Allow a coloured texture to be used
2261
2262* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]2263  is default colour (grey for most systems) not black until a survey is
2264  loaded).
[8faa5d8]2265
2266* aven: Fixed weird "shadowed" icons.
2267
[920b066]2268Changes in 1.1.1 (2004-10-06):
[a7aa27d9]2269
2270* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]2271  startup.
[a7aa27d9]2272
2273* aven: Delay loading the bitmap for the "About" dialog until it is first
2274  needed.  We want start up to be as quick as possible.
2275
[920b066]2276Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]2277
[91e416e]2278* NOTE: Survex 1.1.X releases are development snapshots made available for
2279  the purposes of allowing wider testing and getting more user feedback.  Once
2280  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]2281
[91e416e]2282* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
2283  you're using Windows 95 - these can be obtained from:
2284  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]2285
[91e416e]2286* aven: Solid passages - passage dimensions are currently inferred from
2287  the leg length (pretty effective as you can measure longer legs in
2288  larger passages).  Use of real LRUD data coming soon...
[edb6576]2289
[91e416e]2290* aven: Depth colouring is now continuously varying.
[edb6576]2291
[0580c6a]2292* aven: Colour by depth can now be turned off (and there's the start of a
2293  framework for properly implementing colour by date, error, etc).
2294
[4261983]2295* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
2296  match (? matches any character, * matches any number of characters).
2297
2298* aven: We now use the status bar for coordinates, distances, etc to make
2299  better use of screen space.
[edb6576]2300
[f80077a]2301* aven: Full screen mode (F11).
[edb6576]2302
[6abab84]2303* aven: Perspective view.
2304
[91e416e]2305* aven: Context sensitive cursor shape - needs more work.
[edb6576]2306
[91e416e]2307* aven: Mouse actions changed (hopefully they're now more natural, but
2308  you may find the change disorientating - feedback wanted on this).
[edb6576]2309
[1690fa9]2310* aven: Added "presentations" which allow you to set up fly-through paths
2311  and load/save/run them.
2312
[0580c6a]2313* aven: A presentation can be exported as a movie file.
2314
[045e2af]2315* aven: Added Save screenshot facility.
2316
[c60062d]2317* aven: Depth fogging option.
2318
[0580c6a]2319* aven: Added Smooth Lines option.
2320
2321* aven: Added Textured Walls option.
2322
[f433fda]2323* aven: If a survey has surface legs but no underground legs, default to
2324  showing the surface legs.
2325
[0580c6a]2326* cavern: Dates given to *date are now stored in the 3d file.
