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