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