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