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