NEWS,configure.ac: Update for 1.2.17.

  • Property mode set to 100644
File size: 76.5 KB
Line 
1Changes in 1.2.17 (2015-02-24):
2
3* MacOS X version:
4
5  + Update INSTALL file with current status.
6
7  + Aven.app now has a custom icon.
8
9  + Add icons for all the filetypes supported.
10
11  + Add Finder actions for .svx, .3d, .plt and .pos files.
12
13  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
14    currently do this for us.
15
16  + aven: Fix short-cut for toggling Full Screen mode.
17
18  + aven: Make "About" menu item appear.
19
20  + aven: Fix "Close" button in about dialog.
21
22  + aven: Make custom cursors black with a white outline to match the standard
23    OS X cursor.
24
25  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
26    still doesn't really work like a standard app though - e.g. you can't load
27    files from Finder (instead run svxedit.app and use File->Open), the font
28    size of most menu items is wrong, the icon for the app is the wish icon
29    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
30    probably more.  I'd probably recommend using another editor (OS X comes
31    with TextEdit.app for example).
32
33  + The documentation is now in a "Docs" directory alongside the apps, rather
34    than in the rather less obvious "share/doc/survex" directory.
35
36  + Default to building for x86_64, since all modern Macs are 64 bit.
37
38  + Disable use of liblzma when building wxWidgets for OS X, which was
39    preventing the build from working on OS X 10.6.8.
40
41  + Download wx sources from SF via redirecting link.  Thanks to David A.
42    Riggs.
43
44  + buildmacosx.sh: Handle the mount point for the disk image containing a
45    space.
46
47  + Link with a static build of PROJ for doing coordinate system conversions.
48
49  + Build wx with --disable-webview to avoid a compilation failure on OS X
50    10.10.1.
51
52  + Use wx-config --cc and --cxx to get the compilers to use for building
53    everything else, as wx adds options to them which otherwise cause linking
54    errors.
55
56  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
57    smaller download.  This means OS X 10.4 is required, but we probably
58    already need at least 10.5 because that's the minimum version which the
59    wxWidgets build supports by default.
60
61  + Remove unused files and copies of files from the diskimage.
62
63* cavern: If the same leg is repeated consecutively, average the readings and
64  treat as a single leg.
65
66* dump3d: Report SEPARATOR used by the file being read.
67
68* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
69
70* aven:
71
72  + Greatly reduce flicker when mouse is moved to the top of the screen in full
73    screen mode and the menu bar reappears.
74
75  + For export formats where scaling is supporting, aven now actually uses the
76    scale specified in the export dialog (previously it ignored this and used
77    1:500).
78
79  + Reimplement animation so that it's based on angular change per unit of
80    elapsed time, rather than averaging the time take for the last two scene
81    redraws.  This gives smoother animation in the face of variable load and
82    scene redraw time, and should be more consistent between platforms.
83
84  + Switching to a point of the compass during auto-rotation now jumps straight
85    there rather than the two animations fighting.
86
87  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
88    fast.
89
90  + Disable stepping the rotation angle when animating (previously we only did
91    when rotating).
92
93  + Speed up start-up a bit - rather than loading icons from individual PNG
94    files on disk, compile them into the aven binary.
95
96* (Unix version): Add "MimeType" field to desktop files so that file
97  associations work out of the box with modern desktop environments.
98
99* Add start of Hungarian translation from Imre Balogh.
100
101* Merge in many updates to the Russian translation from "vsuhachev".
102
103* Assorted minor updates to other translations.
104
105* Create scalable (SVG) versions of file type icons.
106
107* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
108  we're using git.
109
110* tests/: Improve test coverage in a few places:
111
112  + Extend tests of fore and back sights to test calibration of the back
113    compass.
114
115  + Test "Can't calibrate angular and length quantities together" error.
116
117  + Check that "*set names ." works when "." is also the decimal point.
118
119Changes in 1.2.16 (2014-10-17):
120
121* aven: Add KML export (stations only currently).
122
123* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
124
125* aven: Fix corrupted names in exported files.
126
127* aven: Fix error log window under wxWidgets >= 2.9 to include the system
128  information before the first log message like it does under wxWidgets 2.8.
129
130* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
131
132* tests/: Improve test coverage.
133
134* Translation updates for many languages, plus the start of translations to
135  Greek and Polish.
136
137* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
138  by Martin Sluka.
139
140* Fix warnings when compiling with clang (which is the default compiler on
141  Mac OS X).  Reported by Martin Sluka.
142
143Changes in 1.2.15 (2014-08-14):
144
145* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
146  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
147  means that we now support all the coordinates systems which Therion does,
148  except for a few which don't have X=East and Y=North.  The documentation
149  for *cs has also been improved.
150
151* aven: We no longer persist full screen mode between runs - it's not a
152  standard behaviour of desktop programs, and it's too easy to go into full
153  screen mode from the menu and then not be able to get out again because you
154  don't know the required key shortcut. (ticket#39)
155
156* aven: When in full screen mode, moving the mouse to the top of the screen now
157  makes the menu bar appear.  This provides a non-shortcut way out of full
158  screen mode, as well as making it easier to perform other operations while in
159  full screen mode.  The current implementation gives an annoyingly flickery
160  transition, but hopefully we can improve this in future. (ticket#39)
161
162* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
163  development), we now call EnableFullScreenView() which improves the full
164  screen mode experience on OS X 10.7 and later.
165
166* img library: Improve documentation for img_ERROR_INFO.
167
168* tests/: Ship some missing .out files and compare.tst.
169
170* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
171  testcase, and extend it to cover a variant of the situation reported as a bug
172  in therion by Bill Gee to the therion list.
173
174* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
175  for the survex package and on tk for the svxedit package.
176
177Changes in 1.2.14 (2014-07-05):
178
179* img library: Add ability to store a PROJ4 string describing the coordinate
180  system in use in 3d v8 files.
181
182* aven: If the 3d file specifies a coordinate system, then use it for exporting
183  to formats which need to know (currently GPX).  If the input file doesn't
184  specify the coordinate system, allow the user to enter a PROJ4 string in the
185  export dialog.
186
187* aven: You can now quickly zoom to a particular area by holding down the
188  "Shift" key and dragging with the left mouse button to create a rectangular
189  "rubber band box" around the area you wish to zoom to.  If you release the
190  "Shift" key while still dragging, the box is centred on the start point
191  rather than having one corner there.
192
193* aven: Fix exporting of passage tubes in elevations and extended elevations
194  - previously up and down were getting drawn across the page!
195
196* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
197  1.2.13.  (Reported by Brian Clipstone)
198
199* aven: Fix the conditions on which the menu item "Cancel measuring line" is
200  enabled - previously it was hard to actually cancel it via the menu.
201  Reported by Hugh St Lawrence.
202
203* aven: Fix wx assertion failures when showing hit test debug view on platforms
204  such as 64-bit Linux.
205
206* aven: When viewing from above, show "Plan" above the "clino" which indicates
207  the tilt angle (instead of "Elevation -90°").
208
209* aven: The extended font data now loads faster, and also uses less memory on
210  64-bit platforms.
211
212* aven: Dragging the vertical divider between the side panel and the 3D view
213  now only updates when you finish the drag, as redrawing continuously just
214  looks clunky except on an ultra-fast machine.
215
216* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
217  the space available in the aven UI.
218
219* cavern: Add a *cs command to allow setting the coordinate system for *fix
220  commands, and the coordinate system used for processed survey data.  The
221  latter is now stored in 3d v8 format files.
222
223* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
224  and handle it in the same way as the "DUPLICATE" flag in .svx files.
225
226* cavern: If there's more than one *fix command with coordinates, still
227  actually fix the second and subsequent ones, to avoid triggering bogus errors
228  about unconnected surveys.
229
230* cavern: If there's more than one *fix command with coordinates, report the
231  station name of the previous one, plus the file and line number where it was.
232
233* cavern: Fix handling of the rather contrived case of *fix with no coordinates
234  followed by *solve and then another *fix with no coordinates not to access
235  freed memory.
236
237* dump3d: Report any specified coordinate system.
238
239* doc/3dformat.htm: Update to document how the coordinate system is stored.
240
241* (Microsoft Windows version): Include dump3d in the installer.
242
243* Fix a compiler warning.
244
245* Improve test coverage.
246
247Changes in 1.2.13 (2014-05-15):
248
249* aven: Fix --print option to wait for printing to happen before exiting
250  (previously it would exit right after opening the print dialog, so you
251  couldn't actually print anything out using it).
252
253* aven: Increase the threshold for how close the pointer needs to be to a
254  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
255  Hugh St Lawrence.
256
257* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
258  if increasing the minimum pointer to station threshold helps Hugh's problems
259  with using aven on a touch screen device.
260
261* aven: The measuring line was unable to see stations which had just been
262  revealed by toggling surface or underground legs on - this is now fixed.
263
264* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
265  many entries are in each box (toggled by F3).
266
267* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
268  off and back on.
269
270* aven: Create the empty hit-test grid data structure lazily, to reduce start
271  up time a little.
272
273* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
274  and *end commands to instead talk about "survey names".
275
276* cavern: For ages cavern has warned if you reentered a survey, but this
277  warning was suppressed if it occurred at the same line of the same file as
278  the survey was first entered, but this can only happen if you include the
279  same survey file more than once, which isn't a sensible thing to do for a
280  file with actual survey data in (you might reasonably do it to set up survey
281  grade details or something like that).  The warning is now given in this
282  situation too.
283
284* cavern: After 5 warnings about reentering a survey we give up warning about
285  it, but we used to keep reporting where the survey was originally entered -
286  this secondary diagnostic message is now silenced when the main message is.
287
288* (Microsoft Windows version): Compile C code with optimisation on.
289
290* Add the start of a Russian translation, with messages take from therion.
291
292* Minor translation updates to French.
293
294* Fix compiler warning from GCC.
295
296* Testsuite improvements:
297
298  + Test that "..." anon station works.
299
300  + cavern.tst: Check number of errors returned by all testcases which should
301    fail and give an error count.
302
303  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
304
305Changes in 1.2.12 (2014-04-14):
306
307* aven: Fix measuring line to show change in altitude rather than altitude
308  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
309  Clipstone.
310
311* aven: Fix printing when built with wxWidgets 3.0.
312
313* aven: Several visual improvements to printouts:
314
315  + Move the numbers below the scale bar down a little so that they don't
316    overlap the scale bar ticks.
317
318  + Set the clipping region after we draw the page border and info box to avoid
319    clipping the border in print preview.
320
321  + Tidy up the appearance of the compass and elevation arrow.
322
323* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
324  <http://bugs.debian.org/739332>.
325
326* aven: Fix to build with older libav where avcodec_free_frame() isn't
327  available.
328
329* (Linux version) survex.spec: Update spec file used for building RPM packages.
330
331* (Unix version): Add "Keywords:" entry to .desktop files.
332
333* (Unix version): Enable large file support, mostly to support filing systems
334  which return 64 bit inode values, such as CIFS mounts.
335
336* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
337  rather than any character which is a letter in the current locale.
338
339* Various translation updates.
340
341Changes in 1.2.11 (2014-01-28):
342
343* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
344  Reported by Kevin Dixon.
345
346* aven: Embed the font data for the first 256 Unicode characters for use in the
347  survey pane into the compiled aven binary to reduce start up overhead.  Any
348  additional characters needed are loaded from a data file only if/when a
349  character >= U+100 is actually needed (as before).
350
351* aven: Fix display of Unicode characters above 256 when there's a character
352  <= 256 earlier in the same string.
353
354* aven: Use the actual width of Unicode characters above 256 rather than
355  assuming they are 16 pixels wide.
356
357* aven: If full screen, don't show the side panel when a new file is opened
358  (e.g. via Ctrl+O).
359
360* aven: Don't give an assertion failure when showing passages for a cave with
361  no vertical extent.  Reported by Jonny Prouty.
362
363* aven: Change terminology in print dialog - say "legend" instead of "info
364  box".
365
366* aven: Add option to show the tilt angle as a percentage gradient.
367
368* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
369  indicators.
370
371* aven: All length units are now translatable.
372
373* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
374  will reduce code size and also the number of deprecation warnings about
375  gluErrorString on Mac OS X 10.9.
376
377* (Microsoft Windows version): aven: Try to work around redraw issues related
378  to the measuring line by redrawing the whole window, which doesn't seem to be
379  measurably slower.
380
381* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
382  give an error rather than quietly ignoring the attempt.
383
384* cad3d: Make cad3d remap control characters and spaces in station names when
385  generating PLT output in the same way aven does.
386
387* Various translation updates (particular thanks to Eric Madelaine and Dennis
388  Baudys), including the start of a Bulgarian translation, with messages taken
389  from Therion and elsewhere.
390
391* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
392  GetUserDefaultUILanguage() to get the UI language to use.  For older
393  versions, continue to use GetUserDefaultLCID().
394
395* (Microsoft Windows version): The Indonesian translation will now be used
396  automatically when the system language is set to Indonesian.
397
398* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
399  A. Riggs for his work on this.
400
401* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
402  checksum check for the downloaded wx sources.
403
404* Fix a lot of the compiler warnings when building with clang.
405
406* doc/manual.sgml: Add missing quantities to the list documented as accepted by
407  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
408  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
409  mentioned in list of the units that can be set for them); COUNT (missing
410  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
411  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
412
413* Test suite: Improve test coverage for cavern.
414
415Changes in 1.2.10 (2014-01-15):
416
417* aven: Fix assertion if two mouse buttons are held down at the same time.
418  If dragging with more than one mouse button held down, releasing one causes
419  another which is still held down to take effect.  Reported by Brian
420  Clipstone.
421
422* aven: If we fail to start the external editor when the user clicks on an
423  error or warning from cavern, show an error box.
424
425* aven: If the survey has a title, add it as a top-level <title> element to
426  exported SVG files.
427
428* aven: Escape '<', '>', and '&' in labels in exported SVG files.
429
430* aven: In GPX export, set the <time> element to the datestamp from the 3d
431  file.
432
433* aven: Don't try to write the title if it isn't set or is empty when exporting
434  GPX files.
435
436* aven: Don't bother looking up the printer page setup info when exporting.
437
438* (Microsoft Windows version): aven: Fix crash on "File->Print" or
439  "File->Export" under Windows XP, reported by Brian Clipstone.
440
441* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
442  encoded filename which could occur if run without being asked to load a file
443  on startup.
444
445* (Microsoft Windows version): aven: Compile with optimisation on.
446
447* img library, aven: Although processed CMAP data files are often referred to
448  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
449  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
450  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
451  continue to do so in case anyone is relying on it, but also check for the
452  other extensions.
453
454* img library: Add new "datestamp_numeric" field to struct img giving the
455  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
456  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
457  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
458  timezone wrong.
459
460* img library: Fix my_strcasecmp() to handle top-bit set characters better.
461
462* cavern: Fix NULL pointer dereference when processing Compass DAT file without
463  'SURVEY DATE:'.
464
465* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
466
467* doc/manual.sgml: Note the station length limit Smaps used.
468
469* Fix some compiler warnings if built with glibc's fortify source feature
470  enabled.
471
472Changes in 1.2.9 (2014-01-08):
473
474* Document --3d-version in cavern man page and the manual.
475
476* aven: Fix compilation error in movie export code with recent libavi.
477
478* aven: Fix warning on stderr when export a movie as MPEG.
479
480* img library: In non-hosted mode, don't define GETC and PUTC if they're
481  already defined, to allow easy overriding with getc_unlocked() and
482  putc_unlocked() (which are significantly faster on Linux).
483
484* img library: In non-hosted mode, check that int is at least 32 bits,
485  and if not, use long.  In practice, platforms with 16 bit int are mostly
486  obsolete, but it's not hard to be portable here.
487
488* img library: Add test that img.c and img.h compile in non-hosted mode
489  (regression test for issue fixed in 1.2.8).
490
491* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
492
493* Update translations from launchpad and from existing similar messages.
494
495* Fix some compiler warnings.
496
497Changes in 1.2.8 (2013-10-29):
498
499* cavern: Fix handling of anonymous wall stations ('..' by default) to
500  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
501  Holder.
502
503* cavern: Tweak .err file output not to lose the space in front of certain
504  statistics when the value gets large.
505
506* cavern: Eliminate redundant progress message when solving simultaneous
507  equations.
508
509* aven: Add a format drop down to the export dialog, and only show fields which
510  are meaningful and supported for the currently selected export format.  The
511  format defaults to that used most recently.  The "Elements" and "View" boxes
512  have been swapped in the print and export dialogs as that layout works much
513  better when the "View" box is hidden.
514
515* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
516  - now works again.  Reported by Anthony Day.
517
518* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
519  this release the projection which the survey coordinates are in defaults
520  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
521  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
522  projection string.  The ability to specify this projection in a better
523  way is coming soon.
524
525* aven: New export options "Origin in centre" and "Full coordinates" - the
526  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
527
528* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
529  time ago, so update references.
530
531* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
532  with wxMSW 2.9.5.  Reported by Brian Clipstone.
533
534* aven: Make right click in an empty presentation mark the current position and
535  open it to edit, instead of crashing.
536
537* aven: Update movie export code to work with latest libav API.  Reported by
538  Sebastian Ramacher.
539
540* aven: Improve reporting of errors during the process of exporting a movie.
541
542* aven: Don't try to close the movie if we aren't producing one.
543
544* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
545
546* aven: Fix to build with wxMSW 2.9.5.
547
548* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
549
550* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
551  ago, so add a new --skencil option to specify this output format.  The old
552  name (--sketch) is still recognised for compatibility.
553
554* cad3d: Make --marker-size work for Skencil and SVG output.
555
556* dump3d: Make --show-dates option show dates for XSECT.
557
558* img library:
559
560  + Fix to work once more when used outside of Survex (missing definition of
561    max() macro and a bad call to free() in img_close() for a file opened for
562    reading).
563
564  + Use lround() instead of round(), and make the tests around whether we use
565    the library function or the our fallback implementation saner.
566
567  + Fix // comments in C code for portability to pre-C99 compilers which don't
568    support these as an extension.
569
570  + Can now be compiled as C++ as well as as C.
571
572* (Microsoft Windows version): The installer is now built with a newer version
573  of Innosetup, and includes translations for all the languages which Survex
574  itself has any translations for.
575
576* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
577
578* Minor translation updates.
579
580* tests/Makefile.am: Distribute files for "normal_bad" testcase.
581
582Changes in 1.2.7 (2013-07-27):
583
584* Add support for anonymous stations, which are indicated by one, two or three
585  separator characters - with the default separator of '.', that means '.',
586  '..', and '...' are anonymous stations.  Single separator ('.' by default)
587  is an anonymous non-wall point, double separator ('..' by default)
588  is an anoymous wall point at the end of an implicit splay), and triple
589  separator ('...' by default) is an anoymous point (with nothing special about
590  the leg).  A new *alias command allows '-' to be mapped to '..' for
591  compatibility with pocket topo: *alias station - ..
592
593* New version 8 of the 3d format:
594
595  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
596
597  + New explicit file-wide flag for 'this is an extended elevation', rather
598    than modifying the survey title to indicate this.
599
600  + The survey prefix is often unchanged from one leg to the next, so use a
601    spare flag to compactly indicate when there's no label change.
602
603  + The data style of each leg is now stored.
604
605  + The "processed at" time is stored as seconds since 1970 rather than a
606    human-readable string.
607
608  + Since 3d v8 features significant changes to the format, the format
609    documentation for v7 and earlier has been split off into 3dformat-old.htm.
610
611* img library:
612
613  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
614
615  + Handle .pos files containing unnamed stations - don't suck the next line in
616    as the station name, and set img_SFLAG_ANON for them.
617
618  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
619    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
620    elevation, in place of appending " (extended)" to the title.  Internally we
621    still append this to the title (and remove it upon reading) when writing
622    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
623    explicitly in the file.
624
625  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
626
627* aven:
628
629  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
630    now, and the wx developers consider even 2.8 to be rather long in the
631    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
632    formally dropping support for older versions allows a number of workarounds
633    to be removed from the aven source code.  Also, features deprecated in
634    wxWidgets 2.9 are no longer used in our code.
635
636  + Don't run incremental search on every key-press, as on a slow machine the
637    short initial search(es) will take a while but not be useful.  Instead only
638    actually run the search when we're told there are no more key-presses
639    queued up.
640
641  + Implement support for including cross-section information in exported SVG
642    and DXF files (ticket#4).  The DXF export is untested currently.
643
644  + Show splay legs faded by default, with menu options to hide them or show
645    them like other legs.
646
647  + Speed up loading a .3d file with cross-sections by using a map to convert
648    station names to positions.
649
650  + In the cavern log window, don't highlight a file:linenumber if there's no
651    message after it, which avoids highlighting the "Included from" lines
652    wrongly.
653
654  + Fix not to crash when trying to report an error while starting up.
655
656  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
657    the OS X standard shortcut Shift-Command-F (previously we used F11, but
658    that's used by the desktop).
659
660  + Add checks for errors when reading the font file.
661
662  + Remove useless extra quoting when invoking vim to show the location of an
663    error from cavern.
664
665  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
666
667  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
668    in the dialog in sync.
669
670* cavern:
671
672  + Demote errors about invalid dates to warnings, since we've accepted *date
673    for ages without any checks on the value, and so existing datasets
674    probably contain invalid dates and dates in other formats.  (ticket#19)
675
676  + New *alias command allows '-' to be mapped to '..' for compatibility with
677    pocket topo: *alias station - ..
678
679  + We want to warn if there's a clino reading which it would be impossible to
680    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
681    read "93" (it's probably a typo e.g. for "39").  However, the gradient
682    reading from a topofil is typically in the range 0 to 180, with 90 being
683    horizontal.  Really we should allow the valid range to be explicitly
684    specified, but for now we infer it from the zero error - if this is within
685    45 degrees of 90 then we assume the instrument can read between 0 and 180
686    degrees.
687
688  + If the survey isn't all connected, still run survey tree checks and report
689    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
690    Dixon for the report which highlighted this issue.
691
692  + Report a warning if *begin SURVEY has a separator character in SURVEY.
693
694  + Report column numbers as well as line numbers for some cavern errors and
695    warnings.
696
697  + Adjust width of node stats table to fit longest count when there are more
698    than 9999 of a particular order of node.
699
700  + If the argument to *include has an opening double quote but the closing
701    double quote is missing, then skip trying to open the file.
702
703  + Move "Station X referred to just once" warning after non-existent survey
704    check - if both fire, the non-existent survey error is likely to be more
705    relevant.
706
707  + We no longer follow an error for a bad reading in passage data with a bogus
708    "End of line not blank" error, but instead check the remaining readings on
709    the same line.
710
711  + We no longer follow an error about OMIT for a required reading with a bogus
712    "End of line not blank" error.
713
714  + Report an error if the scale factor in *calibrate is zero - it doesn't make
715    sense and probably means someone reversed the arguments to *calibrate.
716
717  + Report the parent include files starting from the outermost, as that's more
718    logical when there are multiple levels involved.
719
720  + If we were expecting a numeric field and instead get something which starts
721    with '+', '-', or '.' but which isn't a number, then fix the error to
722    include that character in the token reported.
723
724  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
725    first item.
726
727* cad3d: Check for errors from img_rewind() and report them.
728
729* dump3d:
730
731  + Build, install and package dump3d as standard - it's useful for grabbing
732    info from 3d files in scripts.
733
734  + Add --show-dates option.
735
736  + Show only 2 decimal places on coordinates and passage dimensions.
737
738  + Report the data style of legs.
739
740  + Report if the file is an extended elevation.
741
742  + Report img_STOP as STOP rather than CODE_0xffffffff.
743
744* Test suite:
745
746  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
747    expected output so it passes reliably.
748
749  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
750    'Deleted' stations upon failure are the more natural way round.
751
752  + Add more testcases, expand some existing testcases, and add expected output
753    for more.
754
755* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
756  appropriate C and C++ compilers to use, and link mingw build statically to
757  avoid needing the libgcc DLL (which newer GCC seems to have by default).
758
759* (Unix version): When determining the character set for command-line tools,
760  check environmental variable LANG after LC_ALL and LC_CTYPE.
761
762* When determining the language, check environmental variable LC_ALL before
763  LC_MESSAGES and LANG (but after SURVEXLANG).
764
765* If we don't find the message file, only give an error if it was specified
766  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
767  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
768  settings.
769
770* There are a handful of hard-coded English message strings for reporting
771  errors trying loading message files, etc.  These are all now ASCII, as if we
772  fail trying to open a message file, it's more likely the encoding isn't
773  set correctly.
774
775* Prune strings we are no longer using and are probably unlikely to use again
776  into a new file po_codes_dead, so that translators don't get presented with
777  them to translate.
778
779* Merge lots of translation updates.  Most translations are now complete or
780  close to complete.
781
782* Add start of Indonesian translation from Arief Setiadi Wibowo.
783
784* Fix various compiler warnings when building from source.
785
786* Include scripts gdtconvert and gen_img2aven in the source distribution.
787
788Changes in 1.2.6 (2012-02-23):
789
790* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
791
792* (Microsoft Windows version): Include JPEG images for aven in the installer
793  package (ticket#35).
794
795* cavern: If we have a reference to a station in a non-existent survey, give a
796  helpful error rather than saying the station hasn't been exported from the
797  survey.  (Bug reported by Martin Green via email)
798
799* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
800  Kahler.
801
802* findentrances: Add findentrances utility from Olaf Kahler which produces a
803  .gpx file with waypoints for entrances.  This needs libproj so is disabled
804  by default for this release - to enable it install the development stuff for
805  libproj and build survex with:
806
807      make FINDENTRANCES=findentrances
808      make install FINDENTRANCES=findentrances
809
810* dump3d: Add support for showing img_ERROR_INFO items.
811
812* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
813
814* Incorporate a French translation from launchpad I'd previously copied the
815  English version of by mistake.  Attempt to correct mistranslation of "survey
816  file".
817
818Changes in 1.2.5 (2012-01-03):
819
820* aven:
821
822  + The survey tree in the left panel is now in sorted order once more.
823
824  + No longer fails with an assertion if used for a long time (we were leaking
825    an OpenGL list each time one had to be regenerated).
826
827  + Now builds with newer FFmpeg library.
828
829  + Draw measuring line in front of the indicators rather than behind them.
830
831  + Loading a new file (or reloading the current one) no longer invalidates
832    the OpenGL lists for the compass and clino, so will be a fraction faster.
833
834* Improve handling of attempts to look up translated messages before the
835  message subsystem is fully initialised (which only happens if there's an
836  error early on).
837
838* Improve the survex(7) man page text, and fix it to be marked as section 7 in
839  the man page source as well as in the filename.
840
841Changes in 1.2.4 (2012-01-01):
842
843* aven:
844
845  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
846    initialised, which doesn't cause problems in some machines, but causes aven
847    to abort on others.  This is now fixed, and there's a check in place to
848    help avoid similar issues in future. (ticket#34)
849
850  + Always use metres or feet for the depth colour key, and chose a consistent
851    precision by looking at the depth range. (ticket#30)
852
853  + Show the depth units below the colour bar rather than after every value.
854
855  + When zooming way in, stay in metres rather than switching to cm.
856
857  + On the scale bar, say “1 mile” rather than “1 miles”.
858
859* Translation updates for Catalan, French and Slovak.
860
861Changes in 1.2.3 (2011-12-31):
862
863* Fix to build with wxWidgets 2.9.2.
864
865* (Mac OS X version):
866
867  + Processing .svx files from aven now works.
868
869  + Remove spurious blank lines from the licence text in "Get Info".
870
871  + Don't create the help menu at all, as it is empty (because the "About"
872    entry goes elsewhere) and sometimes seems to appear in the UI.
873
874  + INSTALL.OSX: Update to reflect current status.
875
876* aven:
877
878  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
879
880  + Improvements to text plotted on the survey pane:
881
882    - Support plotting Unicode character points > 256 by lazily loading the
883      data for them from the font file and plotting them with a direct call to
884      glBitmap(), which is slower but doesn't require a display list per
885      character.
886
887    - Adjust the spacing from fixed width to putting a one pixel gap either
888      side of each one character (so two between adjacent glyphs).  Mostly this
889      reduces the horizontal width, but it adds a pixel for characters like "m"
890      and two in a few cases.
891
892    - Fix .pixelfont file generation to correctly handle characters wider than
893      8 pixels.
894
895  + Fix expected cross shape so don't always reject using texture mapping to
896    draw crosses.
897
898  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
899    as those consisting of just one.  Previously we would trip over the empty
900    tube later.  Such tubes can for example be created by extend if a splay shot
901    is the start or end of a tube.
902
903  + Make the green colour used for entrances in the survey tree the same
904    (slightly darker than before) green used for the entrance blobs.
905
906  + Report the version of the library we're actually running with if built
907    against wx >= 2.9.2.  Make it clear that the version reported is the
908    version *built* with for wx < 2.9.2.
909
910* extend:
911
912  + Copy the end markers for passage tubes.
913
914  + Preserve left and right data for tubes (previously they were set to -1.0
915    which means "no info").
916
917* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
918  was no longer used - it certainly is!
919
920* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
921  messages, and curly single right quote instead of straight ASCII apostrophe.
922  Fall back to using straight ASCII versions if we can't represent them in the
923  current character set.
924
925* Translation updates for Catalan, French, Slovak and Spanish.
926
927* Test suite:
928
929  + Add test coverage for interleaved diving data.
930
931  + Add testcase for diving data with topofil-style distance.
932
933Changes in 1.2.2 (2011-10-06):
934
935* aven:
936
937  + Replace the textured-mapped font drawing with an approach based on
938    glBitmap.  This doesn't suffer from the character alignment issues which
939    the textured-mapped fonts had, and is actually significantly faster on some
940    machines.  The current font used is (mostly) fixed-width, but this isn't an
941    inherent limitation - it was just the easiest font data to convert to a
942    usable format.
943
944  + Fix assertion failure due to rounding differences on loading certain .3d
945    files.  (ticket#26)
946
947  + Fix assertion failure when turning on 3D passages if they stick out higher
948    or lower than any station.  (ticket#29)
949
950  + Fix grid not to disappear when blobs are turned on and blobs are drawn
951    using lines.
952
953  + If a degree sign isn't available in the character set in use, transliterate
954    it to 'dg' rather than skipping it.
955
956  + Fix message which should have been a degree sign but got lost in the format
957    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
958    that bearings in the status bar now have a degree sign after them if they
959    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
960
961  + Fix print dialog to calculate the scale required for "One page" right
962    before it calculates how many pages are required, so we don't end up
963    something other than 1x1 being shown when the user changes settings.
964
965  + Update the calculations for picking a scale and for deciding how many
966    pages are needed to take into account the change in info box height made
967    in 1.2.1.
968
969Changes in 1.2.1 (2011-10-04):
970
971* Translation updates for US English.
972
973* aven:
974
975  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
976    it now shows colours for dates and errors as well as depths.
977
978  + In the colour key for "colour by date", change "No info" to "Undated".
979
980  + Remove the dark grey background from the colour key and just put a single
981    pixel black border around the colours.  This is more in keeping with the
982    other controls, and means the colours are now on a black background so more
983    visually similar to the survey legs.
984
985  + Move the colour key's "Undated"/"Not in loop" entry down a little to
986    improve the appearance.  Make each section a pixel taller.
987
988  + Allow "Colour by X" to be selected even if there's no data for X or only a
989    single value of X used (the colour key is much smaller in these cases, and
990    does still provide some useful information).
991
992  + Fix incorrect calculation of depth colouring for survey legs which straddle
993    a depth band boundary.
994
995  + The scale bar, compass, clino, and colour key now all have right click
996    menus which allow related actions to be performed (especially handy in
997    full-screen mode).
998
999  + Improve the font used on the survey pane - it now contains the '-'
1000    character (so the clino now shows negative angles as negative, and dates
1001    in the colour key are now hyphenated).  Also the spacing and alignment
1002    are a little better, though still not perfect.
1003
1004  + PLT file export now handles spaces and control characters in station names
1005    by escaping them with '%' as in URLs.
1006
1007  + Pressing "Enter" on a station in the tree control now centres the view on
1008    that station.
1009
1010  + The scale bar is now cached in an OpenGL display list since it often gets
1011    redrawn exactly the same - for example, when rotating, panning, etc.
1012
1013  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1014    then forces a refresh of the survey pane.  This is intended as a debugging
1015    aid - if pressing F5 changes the display at all then there's a missing case
1016    where a list should have been invalidated (please report if you find such
1017    a case as it is a bug).
1018
1019  + We now automatically track which OpenGL display lists need to be
1020    invalidated on window width or height changes.
1021
1022  + Increase scale bar maximum width from 65% of the window width to 75% as it
1023    was in 1.0.x (except that if that would overlap the clino we now reduce
1024    that proportion down until it reaches 50%).  Make the limit of zooming in
1025    the same as in 1.0.x.  (ticket#23)
1026
1027  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1028    the application was fullscreen (the dialog got opened under the main
1029    window!)  To work around this, aven would switch out of full screen mode
1030    temporarily while showing a dialog.  This case works properly with recent
1031    wxGTK, so disable our workaround with versions we know work.  Also, apply
1032    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1033    as there's no reason to think we need it for other platforms.
1034
1035  + Grey out the "View North" action when we're already viewing North, and
1036    similarly for other compass points.
1037
1038  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1039    info in the "About" dialog.
1040
1041  + Fix to set the correct filename on the root of the survey tree - previously
1042    the filename of the previous file loaded was used!
1043
1044  + The movie export code now works with newer versions of the FFmpeg libraries
1045    as well as still working with older versions.
1046
1047  + Fix mixed up messages - the print dialog now says "View" on the left
1048    subgroup of controls rather than some unrelated message.
1049
1050  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1051    field which gives the bearing and reduce the height on the info box by the
1052    removed field, so it's now 3cm for plans and elevations, as for extended
1053    elevations.  Report the tilt angle for tilted elevations which it seems has
1054    been missing for ages (it's not in recent 1.0.x either).
1055
1056  + Tweak the exact positioning of informational text on printouts to look
1057    nicer and make better use of the available space.
1058
1059  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1060    dialog.
1061
1062  + Make the sign of the tilt angle for printouts consistent with the sign
1063    shown by the "clino" in the survey pane.
1064
1065  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1066    and similarly for the "Elevation" button.
1067
1068  + (Microsoft Windows version): Sort out appearance of custom cursors.
1069
1070  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1071
1072  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1073    you can't get out again easily, so add code to explicitly check for F11
1074    being pressed and toggle full screen.
1075
1076* (Linux version): Fix the RPM .spec file for where man pages now get installed
1077  and package aven.svg and the vim support files.  (Fixes from James Begley)
1078
1079* "make check" now performs several checks on the translation files.
1080
1081* More messages are now available to be translated.
1082
1083* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1084  the message handling changes in 1.2.0.
1085
1086* Fix warning when compiling with GCC.
1087
1088* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1089  sudo for installing on Unix.
1090
1091* In the manual, replace the instructions for building from source with a
1092  pointer to the clearer instructions in INSTALL.
1093
1094* In the manual, make it clear that installing with administrator rights
1095  also applies to newer platforms than XP.
1096
1097* doc/TODO.htm: Update.
1098
1099Changes in 1.2.0 (2011-09-20):
1100
1101* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1102  English.
1103
1104* tests/smoke.tst: aven no longer requires an X display for --help or
1105  --version, so replace skip of this check with a check that this remains the
1106  case.
1107
1108* We now use the standard .po and .pot file formats for storing translations
1109  (rather than the Survex-specific messages.txt format), and then translate
1110  these into Survex's .msg format.
1111
1112* (Unix version): Move survex man page to section 7 (since it isn't documenting
1113  an actual command).
1114
1115* (Unix version): Write each generated man page to a temporary file, then
1116  atomically rename, to avoid leaving an empty or partial man page behind if
1117  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1118  recurrence of that).
1119
1120* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1121  than /usr/doc/survex.
1122
1123* aven:
1124
1125  + Fix handling of accented characters in the survey pane.
1126
1127  + Aven icon redrawn in SVG format - it's now a vector image which looks
1128    nicer at larger sizes.
1129
1130  + Explicitly request double-buffering, which seems to be needed for systems
1131    with GLX >= 1.3.
1132
1133  + Fix crash while trying to load certain .3d files.
1134
1135  + Movie export code updated to work with more recent versions of FFmpeg.
1136    Currently this is disabled in Microsoft Windows builds, pending getting the
1137    required libraries set up for building releases.
1138
1139  + Reporting of errors during movie export improved.
1140
1141  + Force playback speed to "x1" during movie export.
1142
1143  + Use stock IDs for buttons where appropriate - such buttons may now be
1144    rendered with icons on some platforms.
1145
1146  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1147    ISO8859-1).
1148
1149  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1150    as it's no longer required with modern versions.
1151
1152  + Don't redraw the survey on every mouse movement in the survey pane unless
1153    the measuring line is (or just was) active.  (ticket #17)
1154
1155* cavern:
1156
1157  + Drop "non-fatal" from the report of how many errors there were at the end
1158    of the run - it just confuses users - we won't even get here if there's a
1159    fatal error!
1160
1161  + Add --3d-version option to allow the user to specify the version of the 3d
1162    format to output.  (ticket#21)
1163
1164* img library:
1165
1166  + Make the highest and lowest valid values for img_output_version available
1167    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1168
1169* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
1170  volume actually gets mounted.  Fix URL for downloading wxWidgets.
1171
1172Changes in 1.1.16 (2011-05-16):
1173
1174* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1175  Portuguese, and US English.
1176
1177* Use horizontal ellipses character rather than '...' and right arrow character
1178  rather than '->' where these characters are available.
1179
1180* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1181  GNU ld --as-needed (Debian bug #615781).
1182
1183* img.c:
1184
1185  + Fix code typo for IMG_API_VERSION == 0 case.
1186
1187  + Fix code typo in code used when IMG_HOSTED isn't defined.
1188
1189* doc/TODO.htm: Remove entries which have now been done.
1190
1191* (Microsoft Windows version): aven: We now include all the available
1192  translations for messages from wxWidgets, which means that standard widgets
1193  will appear translated where available even if Survex messages aren't
1194  translated.
1195
1196Changes in 1.1.15 (2010-10-15):
1197
1198* aven:
1199
1200  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1201    follow terminology in manual and elsewhere.  Fixes ticket#15.
1202
1203  + When displaying output from cavern, don't update the window after every
1204    line, but only when we don't have data from cavern pending.  Hopefully
1205    addresses ticket#12.
1206
1207  + If we aren't using GL_POINTS for blobs, draw them using a series of
1208    abutting lines rather than with gluDisk which is faster and gives a
1209    consistent shape.
1210
1211  + Check whether blobs and crosses actually render correctly as points/point
1212    sprites, and if they don't, fall back to drawing them with lines.  The
1213    best method is cached on disk, and rechecked automatically if the graphics
1214    hardware is changed or the drivers upgraded.
1215
1216  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1217    though, so we still enable USE_FNT by default).
1218
1219  + Don't offer "All files" wildcard in presentation save dialog.
1220
1221  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1222    more places.
1223
1224  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
1225    when running cavern from aven.  Fixes ticket#11.
1226
1227* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1228
1229* diffpos: Handle files with duplicate labels in better - extend generates
1230  duplicate labels when it breaks a loop.
1231
1232* Enable eswap-break testcase now that diffpos handles duplicate station names.
1233
1234* New v7 of .3d format which stores survey dates as number of days since
1235  January 1st 1900, so we now support dates from 1900-2078 (rather than
1236  1970-2037) with a smaller file size.  The img API is now versioned - you
1237  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1238  gives the survey dates in days in days1 and days2 instead of as time_t
1239  values in date1 and date2.  Fixes ticket#14.
1240
1241* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1242  former has been the canonical name for some time, with www.survex.com just
1243  redirecting to it.
1244
1245* (Unix version): Use unlocked file I/O if available, which can be much faster
1246  in some cases (we don't need the locking as we don't do multithreaded file
1247  I/O).
1248
1249* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1250  headers.
1251
1252* (Mac version): buildmacosx.sh now works again.
1253
1254* Most tests weren't actually running any testcases (looks like a sh
1255  portability issue).  This is now fixed, and fortunately all tests still pass.
1256
1257* Include the extra .isl translation files for Innosetup in the source archive.
1258
1259Changes in 1.1.14 (2010-07-26):
1260
1261* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1262
1263* aven:
1264
1265  + After processing survey data, if there were warnings or errors, add a
1266    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1267    were only warnings, also add an "OK" button to allow moving on to viewing
1268    the processed survey data (fixes ticket#13).
1269
1270  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1271
1272  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1273    not the ': ' after), and to make the title for the terminal the
1274    warning/error message.  Avoid false positives by checking that '<line>' is
1275    a number.
1276
1277  + Don't double escape the contents of href and target in links in the cavern
1278    log window.
1279
1280  + Improve handling of the splitter window, fixing behavioural glitches in
1281    various cases.
1282
1283  + Highlight stations matching any current search when a file is loaded.
1284    (ticket#9)
1285
1286  + (Mac version): Fix build issue due to Mac OS X polluting the global
1287    namespace with its own "Point" class.
1288
1289  + (Unix version): The Gnome print dialog has its own preview window so
1290    suppress ours if using the Gnome one.
1291
1292  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1293
1294  + (Microsoft Windows version): Fix handling of a double-click on the survey
1295    tree when built with wxWidgets >= 2.8.11.
1296
1297* cavern: Report relevant file and line number for three warnings which didn't
1298  give them before.
1299
1300* (Unix and Mac versions): configure: Update the wx-config probing code -
1301  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1302  point looking for them now.
1303
1304* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1305  for easy installation.  Update it to work with the latest Survex versions
1306  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1307  private wxWidgets, use 2.8.11 not 2.7.0-1).
1308
1309* manual:
1310
1311  + Correctly capitalise "GTK".
1312
1313  + Note that on Linux we only regularly test builds with the GTK+ version
1314    (change taken from 1.0).
1315
1316* Fixed the cad3d man page, which was an empty file in 1.1.13.
1317
1318Changes in 1.1.13 (2010-06-16):
1319
1320* Say "wxWidgets" instead of "wxWindows" consistently.
1321
1322* img.c: Fix small memory leak (filename_opened member).
1323
1324* cad3d, aven: Fix export to SVG when a label contains a '%' character.
1325
1326* aven:
1327
1328  + wxWidgets 2.6.0 or newer is now required.
1329
1330  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1331    work but hasn't been tested recently (all packaged versions of wxWidgets
1332    seem to be Unicode now).
1333
1334  + Fix potential uses of uninitialised variables which may have been causing
1335    occasional glitches when loading a file on start-up.
1336
1337  + Improvements to the handling of the font used for plotting labels and other
1338    text on the survey pane:
1339
1340    - Loading the font file is more efficient.
1341
1342    - Character spacing is improved.
1343
1344    - Default font is now anti-aliased.
1345
1346  + "About" dialog:
1347
1348    - Add "Copy" button to copy the system info to the clipboard for easier
1349      bug reporting.
1350
1351    - List OpenGL extensions last, since there are usually lots of them with a
1352      modern gfx card.
1353
1354    - Fix 100% CPU usage while the "About" dialog is open.
1355
1356  + Processing .svx files:
1357
1358    - Passing a .svx file on the command line now works better.
1359
1360    - Put the survey data log window in a splitter in the usual frame rather
1361      than opening a separate frame for it.
1362
1363    - Auto-scroll the log window until we've reported a warning or error.
1364
1365    - Fix small memory leak.
1366
1367  + The presentation filename now defaults to using the basename of the
1368    currently loaded dataset, but we always prompt before we first save with
1369    such a name.
1370
1371  + Reduce memory usage when saving a screenshot.
1372
1373  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1374    persist the window size (and maximised or fullscreen state) between
1375    invocations.
1376
1377  + Fix reporting of OpenGL errors.
1378
1379  + Fix glitches when tilting while looking East.
1380
1381  + Added Portuguese and Slovak translations of wxWidgets messages.
1382
1383* Documentation:
1384
1385  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1386
1387  + Drop the "alternative manual formats" self-extracting zip file - people
1388    will generally just want one of the formats, so downloading several
1389    together isn't very useful.
1390
1391  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1392
1393  + GPL.htm: Replace HTML version of licence with a link to the version on
1394    the FSF website.
1395
1396  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1397    low level to be of interest to non-developers, and developers can look at
1398    the source code.
1399
1400* (Unix version): configure: New preferred name for specifying wx-config script
1401  is WX_CONFIG.  WXCONFIG still supported for compatibility.
1402
1403* (Linux version): Source RPM package dropped as you can just build an RPM
1404  package from the source tarball.
1405
1406* (Microsoft Windows version): The installer is now created with a newer
1407  version of InnoSetup, which gives a 10% smaller download.
1408
1409Changes in 1.1.12 (2007-02-07):
1410
1411* aven:
1412
1413  + Remember the window size or maximised/fullscreen state between invocations.
1414
1415  + Add options dialog to "Export" similar to the one for "Print".
1416
1417  + The "number of pages required" in the print dialog now updates when you
1418    change what is to be shown (underground legs/surface legs/station
1419    names/crosses).
1420
1421Changes in 1.1.11 (2006-11-25):
1422
1423* Updated Czech, Spanish, and Slovak translations.
1424
1425* (MacOS X version): Assorted OS X specific tweaks and fixes.
1426
1427* aven:
1428
1429  + Pick a smaller and clearer font for labels.
1430
1431  + Fix character spacing.
1432
1433  + Tweak display of bearing and elevation angles to look nicer with
1434    proportional fonts.
1435
1436  + Use the title from the 3d (or plt, etc) file for the window title
1437    rather than the filename.
1438
1439  + Show distances to 2 decimal places rather than the nearest integer.
1440
1441  + Only consider underground legs when calculating the depth bands and
1442    depth colouring.
1443
1444  + Add "Colour by Error".
1445
1446  + Add entry for "white" in date and error keys.
1447
1448  + When setting the view to a single point, don't change the scale.
1449
1450  + If reloading the same file, don't change the view
1451
1452  + Fix filetypes selector in open dialog.
1453
1454  + Fix the charset we use for aven in certain cases.
1455
1456  + Call msg_init before using msg_lang or it won't ever be set!
1457
1458  + Pass wx the full language code to initialise the C library locale.
1459
1460  + Fix bug in generating prefix tree view which could lead to a bogus
1461    leading dot on some survey names (bug probably introduced in 1.1.10).
1462
1463  + "New Presentation" now ensures that the side panel is open
1464
1465  + Fix updating of cached opengl lists when the view is reset to the
1466    default.
1467
1468* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1469  LANG which AutoCAD installation seems to set on MS Windows.
1470
1471* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1472  specified.  Either/both can be set to ":".
1473
1474* dump3d: Report unknown (to dump3d) codes returned by img.
1475
1476* img library: Flag all stations as underground in the old "ASCII" .3d format.
1477
1478Changes in 1.1.10 (2006-07-14):
1479
1480* aven: Clicking on a survey name in the survey tree now highlights it in
1481  the map view.  Double-clicking zooms the view to show the clicked survey
1482  highlighted.  Clicking the root clears the highlighting and double-clicking
1483  the root restores the default view.  To expand/collapse a branch, click
1484  on the "[+]" or "[-]" icon to the left of the survey name.
1485
1486* aven: The measuring line can now measure to anywhere in plan or elevation
1487  view (not just to a station!)  In plan view the horizontal distance and
1488  bearing are shown, while in elevation view the vertical distance is shown.
1489
1490* aven: Moving the mouse over a station in the survey view now highlights
1491  that station in the survey tree (though it may not be visible if the
1492  survey(s) it is in aren't expanded).
1493
1494* aven: Clicking on a station to centre the view now moves the mouse pointer
1495  to the new location of the station (except on Mac OS X where this isn't
1496  allowed).
1497
1498* aven: Fix which presentation toolbar buttons are shown as depressed.
1499
1500* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1501
1502* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1503
1504Changes in 1.1.9 (2006-07-04):
1505
1506* (Unix version): Install desktop files for aven and svxedit contributed to the
1507  Ubuntu package by Phil Bull, and corresponding pixmaps.
1508
1509* Fix img to filter out cross-sections which don't match the subsurvey (if
1510  specified).  The API now returns img_XSECT_END to mark the end of a
1511  passage rather than setting a flag on the last img_XSECT of the passage.
1512
1513* Enhance integration with the vim editor - this can now colour .err files, run
1514  cavern from vim and parse error output, and run aven from vim.  Tweak the
1515  existing vim mode for .svx files to fix a few minor bugs and add support for
1516  the new "*data passage" style.
1517
1518* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1519  which can't draw large enough blobs for us.
1520
1521* aven: sort out confusion about what encoding everything is in which means
1522  that the distance measured by the measuring line actually gets displayed
1523  and also fixes problems with empty menu items in non-English locales in
1524  some cases.
1525
1526* aven: redraw grey background after a menu is closed over the aven window
1527  with no survey loaded.
1528
1529* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1530
1531* aven: avoid crash on some machines when opening "About" dialog before having
1532  loaded a survey.
1533
1534* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1535
1536* (Unix version): aven: Fix character set handling of cavern output.
1537
1538* cavern: Report an error if a cross-section is specified for a station which
1539  doesn't exist.
1540
1541* Updated French and Italian translations.
1542
1543* (Unix version): aven: Fix "Can't open message file `en_US' using path
1544  `${prefix}/share/survex'" error.
1545
1546* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1547  (doesn't affect Survex itself, but other applications which use img.c should
1548  update their copy).
1549
1550* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1551  and later are caught by configure, whereas older wx versions are caught when
1552  trying to compile).
1553
1554Changes in 1.1.8 (2006.06.30):
1555
1556* Drop support for building with wxWidgets versions prior to 2.4.0
1557  (which was released on 2003-01-07).
1558
1559* aven: Printing through aven now uses settings from the "[aven]" section
1560  of print.ini, and support for hierarchical sections (using "like=")
1561  has been disabled.
1562
1563* aven: Change mouse actions to be compatible with those in Survex 1.0.
1564  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1565  left drag is now smart about not rotating and zooming at the same
1566  time.
1567
1568* aven: Highlighting stations now happens as you type, and pressing
1569  "Enter" or clicking the "Find" button now pans and zooms to show the
1570  highlighted stations.
1571
1572* aven: Left-clicking away from a station now cancels measuring line.
1573
1574* aven: Setting view to North, South, East, or West is now animated like
1575  the tilt from plan to elevation.
1576
1577* aven: Fix presentation saving to also write "." for decimal points and
1578  presentation loading to accept either "." or ",".
1579
1580* (Unix version): aven: Add text for all toolbar items so that aven
1581  will work with the Gnome desktop preference for displaying toolbars as
1582  icons with text or just text (wxWidgets needs fixing first though).
1583
1584* (Unix version): aven: Remove the ability to detach the menu bar (yell
1585  if you actually used it and I'll restore it!)
1586
1587* aven: Add "all survey files" option to the "open file" dialog.
1588
1589* (MS Windows version): aven: Fix cursor keys to pan survey.
1590
1591* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1592
1593* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1594  run by an unprivileged user.
1595
1596* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1597  installer builder we use) and include new installer translations for
1598  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1599
1600* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1601  translations of messages for wxWidgets (the GUI library we use).
1602
1603* aven: Disable "Highlight exported points" if there aren't any.
1604
1605* Updates to French translation from Michel Bovey.  Also updates to German,
1606  Italian, Catalan, Spanish, and Romanian translations.
1607
1608* (Unix version): test suite: fix smoke test to pass even without X running
1609  (it was meant to but the code had a bug).
1610
1611* aven: Check if OpenGL is available and exit cleanly with a helpful error
1612  if it isn't.
1613
1614* (Unix version): aven: Fix --help and --version to work without a working
1615  X display (provided it's built with wxWidgets 2.5.1 or newer).
1616
1617* aven: Automatically select the presentation tab of the notebook when the user
1618  selects "New Presentation" or "Open Presentation".
1619
1620* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1621  reset to default view as well).
1622
1623* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1624  empty.
1625
1626* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1627  up and down instead of being passed on and moving the survey.
1628
1629* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
1630  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1631  Safari 2.0.3, and InkScape 0.42.
1632
1633* aven: Put a 5mm border around exported SVG files to allow for station markers
1634  and non-zero width lines.
1635
1636* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1637  was turned on.
1638
1639* aven: Actually close the file we're exporting which fixes problems with it
1640  not always being fully written.
1641
1642Changes in 1.1.7 (2005.10.18):
1643
1644* cavern: Add validity checking for dates in *date commands (with feature
1645  test in testsuite).  A date entered as just "year" or "year.month" now
1646  becomes a date range for the relevant period (previously it became a single
1647  date near the middle of that period).
1648
1649* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1650  with MS Windows).
1651
1652* extend: Default output name for a file called input.3d is now input_extend.3d
1653  rather than just extend.3d (which was annoying if you wanted to extend
1654  several surveys in the same directory).
1655
1656* aven: OpenGL 2.0 always includes support for point sprites so rework
1657  our check for them to include that knowledge.
1658
1659* aven: Regenerate depth bar if user switches to/from metric units.
1660
1661* aven: Don't clear the "there" mark just because the mouse pointer has
1662  moved off a station.
1663
1664* aven: When processing a .svx file, put the resultant .3d file in the
1665  same directory (since that's where we then try to load it from).
1666
1667* aven: Fix labelling of date colouring on 32 bit platforms.
1668
1669* aven: If "colour by date" is on and we load a survey with no date info
1670  (or all surveyed on the same date) then set "colour by none".
1671
1672* aven: Make the error dialog modal and remove a signal handler once it
1673  has fired to prevent endless (or seemingly endless) cascades of error
1674  dialogs.
1675
1676* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1677  if a survey file with only one station in is loaded.
1678
1679* aven: Fix problems with indicators disappearing when we're drawing
1680  blobs and/or crosses the slow (but always supported) way.  (Problem
1681  introduced in 1.1.6).
1682
1683* (Unix version): aven: Really stop setting extra toolbar margin when using
1684  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1685  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1686
1687* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1688  we've been compiled with, and which GTK+/Motif version where appropriate.
1689
1690* (Unix version): Fixed build on Fedora Core 3.
1691
1692* documentation: Updates to 3d file format specification from Mike McCombe.
1693
1694Changes in 1.1.6 (2005.10.10):
1695
1696* (MS Windows version): Distribution is about a third smaller than 1.1.5
1697  (mostly because mingwm10.dll is no longer required).
1698
1699* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1700  it, showing cavern's output in a window (with errors and warnings clickable
1701  to load the offending file into an editor), and then loading the resulting
1702  3d file.
1703
1704* aven: Added "Colour by Date" option.
1705
1706* aven: Disable "Colour by Depth" option if there's no elevation variation.
1707
1708* aven: Don't crash if trying to load a survey with no elevation variation.
1709  Instead turn off depth colouring.
1710
1711* aven: Export as HPGL added.
1712
1713* aven: Improved update of mouse coordinates and measuring line (thanks to
1714  Martin Green).
1715
1716* aven: Show the coordinates of either the mouse pointer or the nearest
1717  survey station to it (if there is one near enough).  Showing both was
1718  confusing and meant the status bar overflowed on smaller displays.
1719
1720* aven: When printing an extended elevation, don't show bearing and elevation.
1721
1722* aven: Don't lock "flat" surveys which aren't extended elevations - a
1723  flat survey with LRUD data isn't flat any more!
1724
1725* aven: When we have to draw blobs and crosses the slow way (because the
1726  graphics hardware doesn't support the fast way), draw them so that they
1727  should appear at the correct depth into the 3D scene instead of on top
1728  of everything else.
1729
1730* aven: Make "play presentation backwards" icon green to match the other
1731  presentation icons.
1732
1733* (MS Windows version): aven: Mouse clicks on the survey view now set the
1734  keyboard focus there.
1735
1736* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1737
1738* (MS Windows version): aven: Fix redrawing of measuring line.
1739
1740* cavern: Store dates for img_XSECT.
1741
1742* cavern: Fixed small one-off memory leak if you specify -o more than once.
1743
1744* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1745  language to use for messages.
1746
1747* (MS Windows version): "Print" on a 3d file now prints through aven rather
1748  than the separate printer driver (Unix has done this for some time).
1749
1750* Removed old printer drivers.
1751
1752* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1753  to write a file format version which doesn't support it.
1754
1755Changes in 1.1.5 (2005.09.20):
1756
1757* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1758
1759* aven: Make blobs round like they are in Survex 1.0.
1760
1761* aven: If the graphics drivers don't support drawing blobs using OpenGL
1762  point markers, fall back to drawing filled circles.
1763
1764* aven: If the graphics drivers support it, draw crosses as texture mapped
1765  OpenGL point markers which is much faster.
1766
1767* aven: Cross size increased to match Survex 1.0.
1768
1769* aven: We must update which blobs are displayed if display of surface or
1770  underground legs is toggled.
1771
1772* cavern: Fix handling of a *solve followed by survey data, none of which is
1773  attached to the previous data.
1774
1775* cavern: Fixed "No survey data" error when a *solve is followed by another
1776  *solve (or the implicit solve at the end of processing) with no data between
1777  them.
1778
1779Changes in 1.1.4 (2005.09.19):
1780
1781* aven: Added Aven's icon to the "About" dialog.
1782
1783* aven: Use localised character for the decimal point (e.g. "," in most
1784  continental European countries).
1785
1786* aven: Previously the survey tree would get focus and then take keypresses
1787  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1788  operate on the cave, and transfer the input focus across when we do.
1789
1790* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1791
1792* aven: Speed up intialisation by delaying creation of OpenGL lists until
1793  they're needed.
1794
1795* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1796
1797* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1798
1799* aven: Reworded "Restore Default Settings" as "Restore Default View".
1800
1801* (Unix version): aven: Set sensible default margins for printing and preserve
1802  any margin values the user specifies between runs (previously margins
1803  defaulted to 0 each time aven was run).
1804
1805* Documentation: Document *DATA PASSAGE in the manual.
1806
1807Changes in 1.1.3 (2005.09.07):
1808
1809* (Microsoft Windows version): Fixed build problems.
1810
1811* cavern: Allow OMIT character (-) for left/right/up/down.
1812
1813* aven: Remove an unnecessary menu separator.
1814
1815* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1816
1817* aven: Make the tooltip for "Hide" show the number of found stations.
1818
1819* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1820
1821* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1822  when there's a presentation loaded.
1823
1824* aven: Make entrances green in side panel tree list to match green blobs used
1825  in cave view.
1826
1827* aven: Don't show surface labels if we're not showing surface data, etc.
1828
1829* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1830  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1831  existing users are happy, but don't advertise it.
1832
1833* aven: Normalise filename by adding any extension used, and use the normalised
1834  filename for file history and window title.
1835
1836* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1837  as the toolbar buttons already have a sensible margin - the extra margin is
1838  only needed with GTK1.2.
1839
1840* aven: Fix handling of plumb legs in tube model.
1841
1842* aven: Fixed swapped L and R in tube model.
1843
1844* extend: Preserve UD cross-section information in extended elevation.
1845
1846* extend: Add new messages for John Pybus' enhancements.
1847
1848Changes in 1.1.2 (never formally released):
1849
1850* Added support for LRUD data in .svx files, in .3d files, and aven can
1851  now load and display it on screen and on printouts.  The ability to "fake"
1852  LRUD data in aven is gone for now but will reappear in some form later.
1853
1854* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1855  fold any desirable missing chasm functionality into aven.
1856
1857* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1858  cursors for each different mouse action to help the user learn what each
1859  does.  Also added cursors for the "compass" and "clino" as well as the
1860  scalebar to suggest to the user that they can be dragged to change the view.
1861
1862* (Unix version): aven: Don't segfault if LANG isn't a known language.
1863
1864* tests/smoketest.tst: If X windows is running, check that we can run aven
1865  with --help and --version.
1866
1867* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1868  no results are listed for it.  This revealed that there was a "newline" test
1869  which should have been called "badnewline", and was a broken testcase too!
1870  Fixed all these problems.
1871
1872* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1873  and omitted forward compass/clino readings in Compass DAT files.  Added
1874  a feature test for this to the testsuite.
1875
1876* It no longer makes sense to have an option not to build aven or to build aven
1877  without OpenGL so remove old machinery for this from configure and the
1878  sources.
1879
1880* (Unix version): configure: Check if "-lXxf86vm" is needed.
1881
1882* configure: Better output for strcasecmp test.
1883
1884* aven: Fix crosses to work much better.  Not a total fix - their position
1885  in the Z buffer isn't correct and they're rather slow to plot.
1886
1887* aven: Don't regenerate the hittest grid every time the mouse moves while
1888  animating, which solves the mysterious pausing effect (thanks go to Martin
1889  Green for spotting this!)  Also clear all the status bar coordinates when
1890  animating.
1891
1892* aven: Sort out clashing menu shortcuts in some languages.
1893
1894* aven: Fixed compilation problem on x86_64
1895
1896* SPUD: Pruned out stuff which has been done or which is not actually relevant
1897  to this branch.
1898
1899* Merge various changes from 1.0 branch:
1900
1901  + aven: Port over "printing from aven" functionality.
1902
1903  + aven: Port over "export as" functionality,
1904
1905  + Add David Loeffler's vim mode for .svx files.
1906
1907* aven: Fix check for whether a label is behind us in perspective view.
1908
1909* aven: Don't use an opengl list for drawing the indicators - we typically make
1910  a new list each time we plot them anyway.
1911
1912* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1913
1914* aven: Set icon on non-Windows platforms too.  This means that with
1915  WindowMaker on Unix you get an icon on the AppIcon by default.
1916
1917* configure: Update wxWindows checks to handle newer wx versions.
1918
1919* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
1920  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
1921  for anyone building from CVS).
1922
1923* acinclude.m4: Quote macro name for fix autotools warning.
1924
1925* Documentation: "tilt up" is "'" not ",".
1926
1927* aven: Add support for mousewheels (to tilt the cave).
1928
1929* aven: Fixed twisted transitions to and from pitches in certain cases.
1930
1931* aven: Pick a sensible initial window size when the user's desktop is spread
1932  over more than one monitor (works best with wx2.5 or newer, but try to do
1933  better with wx2.4 or earlier as well).
1934
1935* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
1936  contents being visible before any survey is loaded.
1937
1938* aven: Allow a coloured texture to be used
1939
1940* aven: Don't initialise until we have data (to the user, this means the window
1941  is default colour (grey for most systems) not black until a survey is
1942  loaded).
1943
1944* aven: Fixed weird "shadowed" icons.
1945
1946Changes in 1.1.1 (2004-10-06):
1947
1948* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
1949  startup.
1950
1951* aven: Delay loading the bitmap for the "About" dialog until it is first
1952  needed.  We want start up to be as quick as possible.
1953
1954Changes between 1.0.32 and 1.1.0 (never formally released):
1955
1956* NOTE: Survex 1.1.X releases are development snapshots made available for
1957  the purposes of allowing wider testing and getting more user feedback.  Once
1958  the code has stabilised the version number will be raised to 1.2.0.
1959
1960* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
1961  you're using Windows 95 - these can be obtained from:
1962  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
1963
1964* aven: Solid passages - passage dimensions are currently inferred from
1965  the leg length (pretty effective as you can measure longer legs in
1966  larger passages).  Use of real LRUD data coming soon...
1967
1968* aven: Depth colouring is now continuously varying.
1969
1970* aven: Colour by depth can now be turned off (and there's the start of a
1971  framework for properly implementing colour by date, error, etc).
1972
1973* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
1974  match (? matches any character, * matches any number of characters).
1975
1976* aven: We now use the status bar for coordinates, distances, etc to make
1977  better use of screen space.
1978
1979* aven: Full screen mode (F11).
1980
1981* aven: Perspective view.
1982
1983* aven: Context sensitive cursor shape - needs more work.
1984
1985* aven: Mouse actions changed (hopefully they're now more natural, but
1986  you may find the change disorientating - feedback wanted on this).
1987
1988* aven: Added "presentations" which allow you to set up fly-through paths
1989  and load/save/run them.
1990
1991* aven: A presentation can be exported as a movie file.
1992
1993* aven: Added Save screenshot facility.
1994
1995* aven: Depth fogging option.
1996
1997* aven: Added Smooth Lines option.
1998
1999* aven: Added Textured Walls option.
2000
2001* aven: If a survey has surface legs but no underground legs, default to
2002  showing the surface legs.
2003
2004* cavern: Dates given to *date are now stored in the 3d file.
Note: See TracBrowser for help on using the repository browser.
