1Changes in 1.2.28 (2016-09-24):
2
3* cavern:
4
5  + Show the contents of the line after error and warning messages while
6    processing survey data, and indicate the region of the line in many cases
7    in the same style that compilers such as GCC and clang use (using the
8    column number we already have, plus new width information).  Based on a
9    patch from Mateusz Golicz.
10
11  + Add column and width information for many more error and warning messages.
12
13  + Fix column for "Separator in survey name" warning.
14
15  + Improve warnings when using a backclino with range 0-180 degrees (reusing
16    the same machinery we already have for a forward clino with range 0-180
17    degrees).
18
19* aven:
20
21  + Include LRUD in printout/export of extended elevations, broken by
22    improvements to export of tilted elevations in 1.2.27.  Reported by Anthony
23    Day.
24
25  + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
26    usefully.  Reported by Anthony Day.
27
28  + Remember scale from previous print or export operation in the same run of
29    aven.  Suggested by Stuart Bennett.
30
31  + Convert range indication below shown line to a highlight on that region
32    of the line in cavern log window.
33
34  + Fix colouring of error/warning without column in cavern log window.
35
36  + Fix click on error/warning without column in cavern log window.
37
38  + Fix highlight of translations of "error" or "warning" containing non-ASCII
39    characters.  This fix for this only works with a Unicode build of
40    wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
41    shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
42    Reported by Mateusz Golicz.
43
44  + Disable selection of text in cavern log window - you can't currently copy
45    it to the clipboard, so until that's implemented it seems better to disable
46    the ability to select it.  Reported by Wookey.
47
48  + Avoid special "1000" scale entry when exporting.
49
50  + Show 1 page when "One Page" selected.
51
52  + Reload processed data when restricting view.  Fixes failure when
53    restricting view on data just processed via aven.  Spotted by Andrew
54    Atkinson and myself.
55
56  + Don't hide blobs and crosses behind terrain.  Reported by Jenny Black.
57
58  + Fix rendering of crosses using point sprites.  The texture being used was
59    misaligned relative to the image used for the visual fidelity check, so the
60    check always failed and point sprites would never be used.  Where point
61    sprites are supported, they're probably the fastest option - on my netbook
62    this change improves FPS by ~6 fold when displaying crosses for a large
63    survey.
64
65  + Support drawing blobs using point sprites.  About 5 times faster than using
66    lines on my netbook.
67
68  + Recheck how best to draw crosses and blobs on the first run after Survex
69    is upgraded (or downgraded) as the rendering code may have changed (we
70    already recheck when the OpenGL hardware or driver changes).
71
72  + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
73    MPEG4 produces smaller output of higher quality, and should be widely
74    supported these days.  And I can't get the MPEG1 output to work without
75    buffer underflows, resulting in a file which doesn't play without
76    glitches.
77
78  + Add OGG video to the list of formats - it's more compact than the others
79    we currently list, though slower to write.
80
81  + Fix export to movie formats for which libav/FFmpeg needs to seek the file
82    being written.  This was broken by changes in 1.2.27.
83
84  + Overhaul movie export for the current FFmpeg API, fixing deprecation
85    warnings when building against a recent version.
86
87  + (Microsoft Windows version): Fix corrupted exported movie files.  1.2.27
88    changed the movie export code to allow writing to files with non-ASCII
89    characters in the names, but the new code failed to open the file in binary
90    mode, leading to corrupt output.  Fixes #81, reported by Erin Lynch.
91
92* Fix to build without FFmpeg/libav, broken by changes in 1.2.27.  Reported by
93  James Begley.
94
95* The Polish translation is now very close to being complete, thanks to a
96  substantial update from Mateusz Golicz.
97
98* Merge catalan translation updates from Adolfo Jayme.
99
100* (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
101  messages get used automatically.
102
103* cavern.tst: Remove random : from after ] - dash ignores the extra character,
104  but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
105
106* cavern.tst: Add expected output for more testcases.
107
108* Remove unwanted execute bit from some testcase data.
109
110* Use https for more URLs which support it.
111
112Changes in 1.2.27 (2016-06-06):
113
114* aven:
115
116  + Right click on a survey in the survey tree now gives a pop-up menu
117    with "Hide others", which restricts the view to just that survey
118    and any subsurveys.  Right click on the root of the survey tree
119    gives a menu with "Show all" to undo any restriction in effect.
120    (Currently these are implemented by reloading the file and using
121    the same machinery as the --survey= command line option, but that will
122    probably change in the future).
123
124  + If there's a sub-survey restriction (from the --survey= command line
125    option or the new UI described above) it is now shown in brackets after
126    the survey tree root.
127
128  + When reloading a survey, preserve the current view position (previously
129    the view was recentred).
130
131  + When reloading a survey, actually preserve the current scale factor
132    (this was meant to happen, but the adjustment was applied in the
133    wrong direction).
134
135  + New "File->Extended Elevation..." menu item provides a way to generate
136    extended elevations for simple cases without having to use the command
137    line.  Suggested by Fleur Loveridge.
138
139  + Don't process key presses if accompanied by an unexpected modifier key.
140    In particular, this means that aven no longer interferes with Alt+<function
141    key> (which is typically handled by the desktop) and Alt+<letter> (which is
142    typically a menu short cut).  Reported by Владимир Георгиев.
143
144  + Reduce file loading time by ~5%.  The station name compare function was
145    something of a hot spot, and optimising it yielded a nice improvement.
146
147  + Allow splay legs to be disabled in when printing and exporting.  Mostly
148    addresses #60.
149
150  + SVG export now shows splay legs thinner and in grey.  See #60.
151
152  + Fix export of rotated plans and tilted elevations - previously plans were
153    always aligned with North up, and elevations which weren't exactly side on
154    were exported as plans.  Reported by Stuart Bennett.
155
156  + Fix offset bounding box for exported elevations.
157
158  + In print/export dialog the bearing value now wraps if you scroll up past
159    360 or down past 0.
160
161  + Fix greying out of LRUD-based controls in the print/export dialog when the
162    view is tilted (i.e. not plan or elevation).  This stopped working in
163    1.2.18 when the pan and tilt spin controls were changed from integer- to
164    real-valued ones.
165
166  + Printouts now show LRUD as pale grey arrows from the station they are
167    measured from.  Based on patch from Michael Sargent.  Closes #65.
168
169  + Take LRUD into account for printout size.  Fixes #72, reported by Erin
170    Lynch.
171
172  + Update movie export code to work with latest version of FFmpeg.
173
174  + Make "Show Log" a toggle, so you can click on the button to take a look at
175    the log, and a second click returns you to the survey view.
176
177  + (Microsoft Windows version): Open the font file in binary mode - it looks
178    like we were lucky and the font file (or at least its current version)
179    would have loaded OK in text mode despite being binary data.
180
181  + (Microsoft Windows version): Exporting to files with non-ASCII filenames
182    should now work.
183
184* cavern:
185
186  + Allow tape or backtape to be omitted.  Reported by Erin Lynch.
187
188  + Grid convergence is now corrected for when using automatically
189    calculated declinations (*declination auto <X> <Y> <Z>).  Requested
190    by Mateusz Golicz on the mailing list.
191
192  + Clear any cached calculated declination upon another *declination auto
193    with different coordinates.  Previously if the date stayed the same,
194    a previously cached declination for the old coordinates was used.
195
196  + Fix check for end of version number array in *required.   We would check up
197    to 12 version components, the last 9 being bogus.  In practice, *require is
198    only likely to be used with up to three components, so this wouldn't be an
199    issue.
200
201  + *begin with an invalid prefix could cause a crash in some cases.  Fixed
202    by patch from Colin Watson.
203
204  + Report column locations for errors to do with readings.
205
206* Merge translation updates from Jean-Marc.
207
208* img library: Better document which members can be set when writing.
209  Highlighted by email query about use of img API from Владимир Георгиев.
210
211* Document how *declination interacts with *calibrate declination if both are
212  used in the same dataset.
213
214* doc/3dformat.htm: Update details of how changes to the current label buffer
215  are encoded to reflect changes in v8.  Reported by Angus Sawyer.
216
217* Use docbook2man instead of docbook-to-man to generated Unix man pages
218  from SGML source.  The latter seems to be no longer actively maintained, and
219  docbook2man now does a similarly good job.
220
221* Use https for survex.com links, and for other sites which support it.
222
223Changes in 1.2.26 (2016-01-07):
224
225* aven:
226
227  + (Microsoft Windows version): Fix to be able to process .svx files with
228    cavern again.
229
230* (Microsoft Windows version): Simplify upgrading process with innosetup
231  installer - if Survex is already installed, we now just install to the same
232  location and use the same start menu folder.
233
234* (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
235  Fixes #79, reported by James Begley.
236
237* (Linux version): survex.spec: Fix to work with RPM 4.13.  Fixes #79, reported
238  by James Begley.
239
240Changes in 1.2.25 (2016-01-05):
241
242* aven:
243
244  + Drop broken code which attempts to fix 2D pitches.  Fixes #73, reported by
245    Erin Lynch.  #76 tracks the issue the removed code was trying (but failing)
246    to address.
247
248  + When animating, don't try to update station info based on mouse movement
249    over the survey tree.
250
251  + Further improve code to handle cavern subprocess in aven.
252
253  + Fix jump to error for filenames containing colons when the error location
254    doesn't have a column number.  Bug noted by Jenny Black.
255
256  + If we encounter bad UTF-8 in cavern output, replace it with a red and white
257    ? in a diamond (previously we gave up showing output at the first bad
258    sequence).  This can happen if you process a .svx file which isn't UTF-8
259    encoded.
260
261  + (Unix version): Don't try to set the terminal window title when opening an
262    editor from the cavern log window - gnome-terminal no longer supports this,
263    and there doesn't seem to be a portable option for specifying the title for
264    terminals which do still support this.
265
266  + (Microsoft Windows version): Also quote for cmd.exe so that paths with
267    spaces in work reliably.  Reported by Marco Cotto.
268
269* cavern:
270
271  + Improve error for mismatched fore/back-sight plumbs, reported by Andy
272    Edwards (see #78).
273
274  + Fix to use correct sd for backcompass.  We were using zero instead, the
275    most obvious effect of which was that the threshold for warning about
276    differing COMPASS and BACKCOMPASS was about 71% of what it should have
277    been, so we were warning in more cases than we should have been.
278
279  + Implement support for specifying a length on backsights - if you're using
280    something like a disto-x, you'll get a distance reading for the backsight
281    too.  Fixes #71, reported by Erin Lynch.
282
283  + Make line counting more robust to mixed line ends.  Noticed in example file
284    from Pete Smart (see #69).
285
286* extend: New --show-breaks option which adds a leg flagged as surface survey
287  between each points at which a loop has been broken.  Suggested by Jenny
288  Black.
289
290* (Unix version): Update filetype metadata to work with modern desktops.
291
292* Fix incorrect reporting of errors reading and writing processed survey data.
293  Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
294  IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
295  external programs using the img library, only Survex).  Reported by Jenny
296  Black.
297
298* Add missing options to extend man page and --help output.  Noted by Jenny
299  Black.
300
301* Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
302
303* Fix broken SGML markup in manual.
304
305* Fix typo in manual reported by Jenny Black.
306
307* Update vim syntax file for newer commands, etc.
308
309* Minor translation updates.  Thanks to Piotr Strębski and Jean-Marc.
310
311* Fix to compile with FFmpeg 2.9.  Reported by Andreas Cadhalpun in
312  https://bugs.debian.org/803863
313
314* Stop maintaining ChangeLog files.  They make merging patches harder, and stop
315  'git cherry-pick' from working as it should.  The git repo history should be
316  sufficient for complying with GPLv2 2(a).
317
318* (Microsoft Windows version): The installer requires admin privileges on Vista
319  and later and OS versions older than Vista are past end of life, so drop code
320  which tries to set up the registry differently depending if we have admin
321  privileges or not.
322
323Changes in 1.2.24 (2015-09-23):
324
325* aven:
326
327  + (Microsoft Windows version): Fix the cavern log window.  Reported by Brian
328    Clipstone.
329
330  + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
331    Reported by Jenny Black.
332
333  + If wx was built with thread support, aven now runs cavern from a separate
334    thread, which works much better under wxMSW (where we can't use select),
335    and also seems a bit smoother on Linux.
336
337  + Fix handling of encoding of filenames when the operating system has no
338    locale installed corresponding to the language selected for Survex's
339    messages.
340
341  + Undo accidentally committed debugging code which was sending message to
342    the terminal in 1.2.23.
343
344* (Linux version): configure now looks first for wx-config-3.0, which Fedora's
345  wx3 packages have.  Reported by James Begley.
346
347* Indonesian translation fully up to date again.
348
349* Manual: Document anonymous stations, based on the text from NEWS.  Reported
350  by Wookey.
351
352Changes in 1.2.23 (2015-09-06):
353
354* aven:
355
356  + Updating the cavern log window is now much smoother, especially on slower
357    machines.
358
359  + Show "busy" mouse cursor while processing survey data.
360
361  + Fix an assertion if you try to start processing a survex file while one is
362    already being processed.
363
364  + Processing a .svx file with an error now still adds it to the file history.
365    Reported by Martin Green.
366
367  + Fix the orientation of the starting end of tubes.
368
369* cavern:
370
371  + New *ref command to allow specifying an external reference (e.g. where to
372    find the original survey notes).
373
374  + Drop support for showing percentage progress in cavern.  It's confusing in
375    a multiple-file dataset as it shows progress in the current file so jumps
376    around.  It also slows down processing, and on a slow machine you'd don't
377    want that, while on a fast machine processing isn't slow enough for the
378    progress display to be useful.
379
380* French translation is now completely up to date, thanks to Michel Bovey.
381
382* Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
383  OS X so that things like "*cs EPSG:29903" work.  Reported by Graham Mullan.
384
385* (Microsoft Windows version): Process survey data with aven rather than
386  running cavern.
387
388* (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
389  releases have been built with 5.5.3) to see if that solves Ray Duffy's
390  reported issue with not having file associations for .svx files created.
391
392Changes in 1.2.22 (2015-08-17):
393
394* aven:
395
396  + Ensure that the window has a depth buffer.  Whether it does by default
397    seems to vary depending on OS and maybe graphics card.  Fixes #55 (terrain
398    is no longer visible through itself), and also the rendering of passage
399    tubes.  Thanks to Martin Green for pointing me in the right direction for
400    finding this fix.
401
402* cavern:
403
404  + Fix *declination with an angle to actually work.
405
406  + Fix assertion if we try to identify a hanging survey by an anonymous
407    station.
408
409  + Improve errors for invalid survey names in *begin, *end, *equate and
410    *export.
411
412Changes in 1.2.21 (2015-07-28):
413
414* aven:
415
416  + Fix exporting to KML and other text-based formats to always use "." for the
417    decimal separator - previously "," would be used when the user's locale
418    specified this for the decimal separator.  Reported by Jan Schorn.
419
420  + Implement exporting of survey legs in KML format.
421
422  + Put "paddle" placemarker icons on stations in exported KML files, using the
423    same colour coding for entrances, fixed points and exported points as aven
424    does.
425
426  + Remove the "Coordinate projection" field from the print dialog, as it isn't
427    relevant there.  Reported by Wookey.
428
429  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
430    been too small).  Reported by Wookey.
431
432  + Don't rescale if the same file is reloaded, but adjust the volume diameter
433    as appropriate.
434
435  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
436    values on Windows.
437
438* cavern:
439
440  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
441    radians, but we were passing degrees, which would generally cause the
442    conversion to the output coordinate system to fail.  Reported by Wookey.
443
444  + Fix *fix with standard deviations when *cs is in use, give an error for use
445    of *fix with standard deviations before *cs.
446
447  + Add new *declination command with support for setting the declination
448    automatically from the IGRF model based on the survey date.  Thanks to the
449    Therion developers for the IGRF support code, which we're reusing.
450    Fixes #54, reported by Wookey.
451
452  + Allow the units for the zero error to be specified, making it easier to
453    specify calibration with a scale if you measure the zero error externally
454    (rather than using the instrument itself).  Fixes #61, reported by Andrew
455    Atkinson.
456
457  + Report the error from PROJ when coordinate conversion fails as part of the
458    actual error rather than on a separate line.
459
460  + Fix use after free after *solve.  This only occurs if a leg between the two
461    exact same stations appears right before and right after the *solve, which
462    is unlikely in real data, but the testsuite has an instance of this.  This
463    was introduced by the repeat leg averaging added in 1.2.17.
464
465  + Fix small memory leak when solving network.  This doesn't really matter
466    when solving at the end of processing as cavern will exit after that, but
467    if *solve is used we continue processing after solving.
468
469* Remove compatibility handling for specifying a country variant of a language
470  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
471  changed to the standard "en_US" way back in 2001.  This code was mangling
472  character sets with a "-" in, and is no longer useful.
473
474* Ignore any "@<something>" modifier in the language code.
475
476* Improve documentation of magnetic declination handling, and cover the new
477  "*DECLINATION" command.
478
479* Document aven's command line options in the manual and its man page.
480  Reported by Jenny Black.
481
482* Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
483  documentation.
484
485* Remove references to SpeleoGen from the documentation - it hasn't been
486  updated for many years, and can't read recent versions of the .3d format.
487
488* Strip documentation references to obsolete versions of MS Windows.
489
490* doc/HACKING.htm: Update list of debian packages to install to build from git.
491
492Changes in 1.2.20 (2015-06-26):
493
494* aven:
495
496  + When printing, use the top margin rather than the right margin to calculate
497    the height of the printable area.  In practice, the two values seem to be
498    the same or very similar by default.
499
500  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
501    Maynard.
502
503  + Optimise the size of the about dialog images.
504
505  + Add support for reading terrain data which isn't in a .zip file.
506
507  + Force a refresh after loading terrain data so that it gets displayed right
508    away.
509
510  + Make checks for terrain data extensions in zip files case insensitive.
511
512  + If reading terrain data fails, always report an error and never try to
513    display it.
514
515* cavern: Allow clino readings in diving style data, suggested by Andrew
516  Atkinson.  Currently these readings are ignored, but a future version will
517  check that they're consistent with the angle given by the depth gauge and
518  tape, and perform suitable averaging.
519
520* Remove lingering traces of svxedit.
521
522* configure: Fix to allow compiling without libav/ffmpeg, as was possible
523  before 1.2.19.
524
525* (Unix version): Install the filetype and aven application icons under
526  /usr/share/icons/hicolor, which is where they're expected to be these days.
527
528* (Unix version): Add %f to Exec in survex-aven.desktop.
529
530* (Mac OS X version): Remove useless extra copy of about box images from OS X
531  disk image.
532
533* (Mac OS X version): Only ship one copy of each of the translations.
534
535* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
536  libav features we don't use.
537
538* (Microsoft Windows version): Reduce the size of the aven binary by disabling
539  a load of libav features we don't use.
540
541* (Microsoft Windows version): Update message files to fix a missing Chinese
542  message in the installer.
543
544Changes in 1.2.19 (2015-06-18):
545
546* aven:
547
548  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
549    the exported file in 1.2.18.
550
551  + Add exporting to Survex .pos format.
552
553  + If the measuring line isn't currently active, pressing "Escape" will now
554    exit full screen mode.
555
556  + (Mac OS X version): Change the shortcut for full screen mode to be the
557    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
558    using since 1.2.7).
559
560  + (Mac OS X version): When we centre the view on the station this can
561    generate a mouse move event, so clear the variable which says we are
562    dragging before we process a left click on a station.  This avoids random
563    rotations of the survey when clicking on a station, reported in #47 by Hugh
564    St. Lawrence.
565
566  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
567    icons from being rescaled and looking fuzzy.
568
569  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
570    toolbar icons from being rescaled, but which requires an unreleased version
571    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
572
573  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
574    the top of the screen, since we can't seem to display the menu bar in this
575    case like we do on other platforms.
576
577  + (Mac OS X version): Enable aven's movie export feature.
578
579  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
580    support multi-monitor setups.
581
582  + (Mac OS X version): Silence warning visible when aven is run from a
583    terminal about a missing CFBundleTypeRole.
584
585  + When reading terrain data from a .zip file, report an error if the .zip
586    file is bad, or if it doesn't contain any terrain data we recognise.
587
588  + Tweak error message in terrain reading code to distinguish two failure
589    cases.
590
591  + Add viewing angles and scale to footer, and shorten some of the other items
592    to make room for this extra information.  (Fixes ticket #52, reported by
593    Erin Lynch)
594
595  + If the footer is wider than the printout width, scale down the font used
596    so that it exactly fits; if the footer is narrower, than space out the
597    items in in so it uses the full width.
598
599  + If the saved size for aven's window exceeds the current display size
600    (mostly likely because we're now plugged into a smaller monitor), then
601    reduce the size of the window to fit the display.  If the saved size is <
602    (480x320), increase it to at least that, as aven isn't usable in a smaller
603    window.
604
605  + Remove crude bodge which tries to pick a nicer initial window size when
606    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
607    with the same size window it had when it was closed, so the initial size is
608    only relevant on the first ever run.
609
610* Assorted translation updates.  Notably Indonesian is at 100% again.
611
612* Stop trying to catch and report signals.  The only real reason to do it is so
613  we can say "Bug in program detected! Please report this to the authors"
614  before we exit, but when the program crashes that's pretty obvious.  In aven
615  we try to pop up a message box for this message, which may fail due to
616  whatever caused the signal, while with the command line tools there's no
617  great benefit over just letting the shell report the signal.
618
619* Use pkg-config to probe for libav and proj, which sorts out the correct flags
620  for building on OS X against a static install of libav.
621
622Changes in 1.2.18 (2015-06-03):
623
624* aven:
625
626  + Add support for reading terrain data (from a zip file containing either an
627    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
628    rendering it as a transparent surface.
629
630  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
631    sanely want to perform from the menu.
632
633  + Create a "Colour by" submenu of the "View" menu to house the various
634    colouring options.
635
636  + Add "Colour by Gradient" and "Colour by Length".
637
638  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
639    which seems more logical, and also allows the dialog to be closed by
640    pressing "Escape".
641
642  + Destroy any existing clipping region before we write the page footer.
643    Hopefully solves ticket #52, reported by Erin Lynch.
644
645  + Don't round bearing and tilt angles to integers when printing and
646    exporting.
647
648  + Add passage export for EPS format.  (Partly addresses ticket #4)
649
650  + Add JSON export.  This should be regarded as experimental, and the format
651    is quite likely to change.
652
653  + Pressing F6 now toggles the display of rendering stats, currently FPS
654    (Frames Per Second) and the number of triangles in the terrain mesh.
655
656  + Add a menu item and toolbar button to show the cavern log window if the
657    currently shown survey data was processed by aven.  Reported by Hugh St
658    Lawrence in #47, and by Dave Clucas and others previously on the list.
659
660  + Add "Save Log" button to Aven's cavern log window.
661
662  + In cavern log window, highlight "error" markers in red and "warning"
663    markers in orange.
664
665  + Rework code to read cavern's output.  In particular, we no longer mix
666    buffered and non-buffered system calls.
667
668  + Aven's support for reading colours and font sizes for printouts from
669    print.ini has never worked - the contents of the ini files are ignored due
670    to a bug which has been there since the code was added in 2005 - but nobody
671    has ever complained.  So just strip out that code entirely - we should
672    support setting the colours and font sizes, but a GUI interface for setting
673    them would be better.
674
675  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
676    Gee.
677
678  + Take the width of the messages used above the compass and clino into
679    account when calculating how much space to allow for them - now the labels
680    won't overlap or be cut off in translations where they are long.
681
682  + (Mac OS X version): Attempt to address the size of the toolbar icons.
683
684* cavern:
685
686  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
687    susscorfa).
688
689  + Use the currently set units when outputting measurements in warnings,
690    errors, and the stats at the end of the run.  Requested by Bill Gee.
691
692  + Include column number when a *include file isn't found.
693
694  + Show 'error' in front of error messages, like we show 'warning' in front of
695    warnings.  Fixes #48, reported by Wookey.
696
697  + Increase the threshold for warning that fore and back measurements differ
698    from 2 SDs to 3 SDs.
699
700* findentrances: If the 3d file specifies the coordinate system, use it.
701
702* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
703  would be nice to have, svxedit doesn't really offer that, and it looks ugly
704  in a modern desktop.
705
706* If we run out of memory while reading a processed survey data file, include
707  the filename in the error message.
708
709* Many translation updates - notably Indonesian and Russian are now the two
710  most complete translations.
711
712* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
713
714* Transliterate gradient and infinity symbols if the current character set
715  lacks them.
716
717* Add SVG version of .plt icon.
718
719* Manual:
720
721  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
722    highlighting that the previous list was incomplete.
723
724  + Document averaging of a group of repeated readings.
725
726  + Add a link to the sample data from the manual.
727
728  + Remove references to contact addresses which are no longer there.  Remove
729    offer to post people floppies, and references to a CD image which isn't
730    available for download.
731
732* Remove non-breaking spaces from the diffpos and extend manual pages, as they
733  actually make the output formatting worse (presumably these used to work
734  around a since-fixed bug in one of the docbook processing tools).
735
736* doc/TODO.htm: Update.
737
738* Fix to compile without warnings with 'g++ --std=gnu++11'.
739
740Changes in 1.2.17 (2015-02-24):
741
742* MacOS X version:
743
744  + Update INSTALL file with current status.
745
746  + Aven.app now has a custom icon.
747
748  + Add icons for all the filetypes supported.
749
750  + Add Finder actions for .svx, .3d, .plt and .pos files.
751
752  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
753    currently do this for us.
754
755  + aven: Fix short-cut for toggling Full Screen mode.
756
757  + aven: Make "About" menu item appear.
758
759  + aven: Fix "Close" button in about dialog.
760
761  + aven: Make custom cursors black with a white outline to match the standard
762    OS X cursor.
763
764  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
765    still doesn't really work like a standard app though - e.g. you can't load
766    files from Finder (instead run svxedit.app and use File->Open), the font
767    size of most menu items is wrong, the icon for the app is the wish icon
768    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
769    probably more.  I'd probably recommend using another editor (OS X comes
770    with TextEdit.app for example).
771
772  + The documentation is now in a "Docs" directory alongside the apps, rather
773    than in the rather less obvious "share/doc/survex" directory.
774
775  + Default to building for x86_64, since all modern Macs are 64 bit.
776
777  + Disable use of liblzma when building wxWidgets for OS X, which was
778    preventing the build from working on OS X 10.6.8.
779
780  + Download wx sources from SF via redirecting link.  Thanks to David A.
781    Riggs.
782
783  + buildmacosx.sh: Handle the mount point for the disk image containing a
784    space.
785
786  + Link with a static build of PROJ for doing coordinate system conversions.
787
788  + Build wx with --disable-webview to avoid a compilation failure on OS X
789    10.10.1.
790
791  + Use wx-config --cc and --cxx to get the compilers to use for building
792    everything else, as wx adds options to them which otherwise cause linking
793    errors.
794
795  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
796    smaller download.  This means OS X 10.4 is required, but we probably
797    already need at least 10.5 because that's the minimum version which the
798    wxWidgets build supports by default.
799
800  + Remove unused files and copies of files from the diskimage.
801
802* cavern: If the same leg is repeated consecutively, average the readings and
803  treat as a single leg.
804
805* dump3d: Report SEPARATOR used by the file being read.
806
807* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
808
809* aven:
810
811  + Greatly reduce flicker when mouse is moved to the top of the screen in full
812    screen mode and the menu bar reappears.
813
814  + For export formats where scaling is supporting, aven now actually uses the
815    scale specified in the export dialog (previously it ignored this and used
816    1:500).
817
818  + Reimplement animation so that it's based on angular change per unit of
819    elapsed time, rather than averaging the time take for the last two scene
820    redraws.  This gives smoother animation in the face of variable load and
821    scene redraw time, and should be more consistent between platforms.
822
823  + Switching to a point of the compass during auto-rotation now jumps straight
824    there rather than the two animations fighting.
825
826  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
827    fast.
828
829  + Disable stepping the rotation angle when animating (previously we only did
830    when rotating).
831
832  + Speed up start-up a bit - rather than loading icons from individual PNG
833    files on disk, compile them into the aven binary.
834
835* (Unix version): Add "MimeType" field to desktop files so that file
836  associations work out of the box with modern desktop environments.
837
838* Add start of Hungarian translation from Imre Balogh.
839
840* Merge in many updates to the Russian translation from "vsuhachev".
841
842* Assorted minor updates to other translations.
843
844* Create scalable (SVG) versions of file type icons.
845
846* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
847  we're using git.
848
849* tests/: Improve test coverage in a few places:
850
851  + Extend tests of fore and back sights to test calibration of the back
852    compass.
853
854  + Test "Can't calibrate angular and length quantities together" error.
855
856  + Check that "*set names ." works when "." is also the decimal point.
857
858Changes in 1.2.16 (2014-10-17):
859
860* aven: Add KML export (stations only currently).
861
862* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
863
864* aven: Fix corrupted names in exported files.
865
866* aven: Fix error log window under wxWidgets >= 2.9 to include the system
867  information before the first log message like it does under wxWidgets 2.8.
868
869* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
870
871* tests/: Improve test coverage.
872
873* Translation updates for many languages, plus the start of translations to
874  Greek and Polish.
875
876* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
877  by Martin Sluka.
878
879* Fix warnings when compiling with clang (which is the default compiler on
880  Mac OS X).  Reported by Martin Sluka.
881
882Changes in 1.2.15 (2014-08-14):
883
884* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
885  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
886  means that we now support all the coordinates systems which Therion does,
887  except for a few which don't have X=East and Y=North.  The documentation
888  for *cs has also been improved.
889
890* aven: We no longer persist full screen mode between runs - it's not a
891  standard behaviour of desktop programs, and it's too easy to go into full
892  screen mode from the menu and then not be able to get out again because you
893  don't know the required key shortcut. (ticket#39)
894
895* aven: When in full screen mode, moving the mouse to the top of the screen now
896  makes the menu bar appear.  This provides a non-shortcut way out of full
897  screen mode, as well as making it easier to perform other operations while in
898  full screen mode.  The current implementation gives an annoyingly flickery
899  transition, but hopefully we can improve this in future. (ticket#39)
900
901* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
902  development), we now call EnableFullScreenView() which improves the full
903  screen mode experience on OS X 10.7 and later.
904
905* img library: Improve documentation for img_ERROR_INFO.
906
907* tests/: Ship some missing .out files and compare.tst.
908
909* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
910  testcase, and extend it to cover a variant of the situation reported as a bug
911  in therion by Bill Gee to the therion list.
912
913* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
914  for the survex package and on tk for the svxedit package.
915
916Changes in 1.2.14 (2014-07-05):
917
918* img library: Add ability to store a PROJ4 string describing the coordinate
919  system in use in 3d v8 files.
920
921* aven: If the 3d file specifies a coordinate system, then use it for exporting
922  to formats which need to know (currently GPX).  If the input file doesn't
923  specify the coordinate system, allow the user to enter a PROJ4 string in the
924  export dialog.
925
926* aven: You can now quickly zoom to a particular area by holding down the
927  "Shift" key and dragging with the left mouse button to create a rectangular
928  "rubber band box" around the area you wish to zoom to.  If you release the
929  "Shift" key while still dragging, the box is centred on the start point
930  rather than having one corner there.
931
932* aven: Fix exporting of passage tubes in elevations and extended elevations
933  - previously up and down were getting drawn across the page!
934
935* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
936  1.2.13.  (Reported by Brian Clipstone)
937
938* aven: Fix the conditions on which the menu item "Cancel measuring line" is
939  enabled - previously it was hard to actually cancel it via the menu.
940  Reported by Hugh St Lawrence.
941
942* aven: Fix wx assertion failures when showing hit test debug view on platforms
943  such as 64-bit Linux.
944
945* aven: When viewing from above, show "Plan" above the "clino" which indicates
946  the tilt angle (instead of "Elevation -90°").
947
948* aven: The extended font data now loads faster, and also uses less memory on
949  64-bit platforms.
950
951* aven: Dragging the vertical divider between the side panel and the 3D view
952  now only updates when you finish the drag, as redrawing continuously just
953  looks clunky except on an ultra-fast machine.
954
955* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
956  the space available in the aven UI.
957
958* cavern: Add a *cs command to allow setting the coordinate system for *fix
959  commands, and the coordinate system used for processed survey data.  The
960  latter is now stored in 3d v8 format files.
961
962* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
963  and handle it in the same way as the "DUPLICATE" flag in .svx files.
964
965* cavern: If there's more than one *fix command with coordinates, still
966  actually fix the second and subsequent ones, to avoid triggering bogus errors
967  about unconnected surveys.
968
969* cavern: If there's more than one *fix command with coordinates, report the
970  station name of the previous one, plus the file and line number where it was.
971
972* cavern: Fix handling of the rather contrived case of *fix with no coordinates
973  followed by *solve and then another *fix with no coordinates not to access
974  freed memory.
975
976* dump3d: Report any specified coordinate system.
977
978* doc/3dformat.htm: Update to document how the coordinate system is stored.
979
980* (Microsoft Windows version): Include dump3d in the installer.
981
982* Fix a compiler warning.
983
984* Improve test coverage.
985
986Changes in 1.2.13 (2014-05-15):
987
988* aven: Fix --print option to wait for printing to happen before exiting
989  (previously it would exit right after opening the print dialog, so you
990  couldn't actually print anything out using it).
991
992* aven: Increase the threshold for how close the pointer needs to be to a
993  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
994  Hugh St Lawrence.
995
996* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
997  if increasing the minimum pointer to station threshold helps Hugh's problems
998  with using aven on a touch screen device.
999
1000* aven: The measuring line was unable to see stations which had just been
1001  revealed by toggling surface or underground legs on - this is now fixed.
1002
1003* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
1004  many entries are in each box (toggled by F3).
1005
1006* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
1007  off and back on.
1008
1009* aven: Create the empty hit-test grid data structure lazily, to reduce start
1010  up time a little.
1011
1012* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
1013  and *end commands to instead talk about "survey names".
1014
1015* cavern: For ages cavern has warned if you reentered a survey, but this
1016  warning was suppressed if it occurred at the same line of the same file as
1017  the survey was first entered, but this can only happen if you include the
1018  same survey file more than once, which isn't a sensible thing to do for a
1019  file with actual survey data in (you might reasonably do it to set up survey
1020  grade details or something like that).  The warning is now given in this
1021  situation too.
1022
1023* cavern: After 5 warnings about reentering a survey we give up warning about
1024  it, but we used to keep reporting where the survey was originally entered -
1025  this secondary diagnostic message is now silenced when the main message is.
1026
1027* (Microsoft Windows version): Compile C code with optimisation on.
1028
1029* Add the start of a Russian translation, with messages take from therion.
1030
1031* Minor translation updates to French.
1032
1033* Fix compiler warning from GCC.
1034
1035* Testsuite improvements:
1036
1037  + Test that "..." anon station works.
1038
1039  + cavern.tst: Check number of errors returned by all testcases which should
1040    fail and give an error count.
1041
1042  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
1043
1044Changes in 1.2.12 (2014-04-14):
1045
1046* aven: Fix measuring line to show change in altitude rather than altitude
1047  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
1048  Clipstone.
1049
1050* aven: Fix printing when built with wxWidgets 3.0.
1051
1052* aven: Several visual improvements to printouts:
1053
1054  + Move the numbers below the scale bar down a little so that they don't
1055    overlap the scale bar ticks.
1056
1057  + Set the clipping region after we draw the page border and info box to avoid
1058    clipping the border in print preview.
1059
1060  + Tidy up the appearance of the compass and elevation arrow.
1061
1062* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
1063  <http://bugs.debian.org/739332>.
1064
1065* aven: Fix to build with older libav where avcodec_free_frame() isn't
1066  available.
1067
1068* (Linux version) survex.spec: Update spec file used for building RPM packages.
1069
1070* (Unix version): Add "Keywords:" entry to .desktop files.
1071
1072* (Unix version): Enable large file support, mostly to support filing systems
1073  which return 64 bit inode values, such as CIFS mounts.
1074
1075* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
1076  rather than any character which is a letter in the current locale.
1077
1078* Various translation updates.
1079
1080Changes in 1.2.11 (2014-01-28):
1081
1082* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
1083  Reported by Kevin Dixon.
1084
1085* aven: Embed the font data for the first 256 Unicode characters for use in the
1086  survey pane into the compiled aven binary to reduce start up overhead.  Any
1087  additional characters needed are loaded from a data file only if/when a
1088  character >= U+100 is actually needed (as before).
1089
1090* aven: Fix display of Unicode characters above 256 when there's a character
1091  <= 256 earlier in the same string.
1092
1093* aven: Use the actual width of Unicode characters above 256 rather than
1094  assuming they are 16 pixels wide.
1095
1096* aven: If full screen, don't show the side panel when a new file is opened
1097  (e.g. via Ctrl+O).
1098
1099* aven: Don't give an assertion failure when showing passages for a cave with
1100  no vertical extent.  Reported by Jonny Prouty.
1101
1102* aven: Change terminology in print dialog - say "legend" instead of "info
1103  box".
1104
1105* aven: Add option to show the tilt angle as a percentage gradient.
1106
1107* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
1108  indicators.
1109
1110* aven: All length units are now translatable.
1111
1112* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
1113  will reduce code size and also the number of deprecation warnings about
1114  gluErrorString on Mac OS X 10.9.
1115
1116* (Microsoft Windows version): aven: Try to work around redraw issues related
1117  to the measuring line by redrawing the whole window, which doesn't seem to be
1118  measurably slower.
1119
1120* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
1121  give an error rather than quietly ignoring the attempt.
1122
1123* cad3d: Make cad3d remap control characters and spaces in station names when
1124  generating PLT output in the same way aven does.
1125
1126* Various translation updates (particular thanks to Eric Madelaine and Dennis
1127  Baudys), including the start of a Bulgarian translation, with messages taken
1128  from Therion and elsewhere.
1129
1130* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
1131  GetUserDefaultUILanguage() to get the UI language to use.  For older
1132  versions, continue to use GetUserDefaultLCID().
1133
1134* (Microsoft Windows version): The Indonesian translation will now be used
1135  automatically when the system language is set to Indonesian.
1136
1137* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
1138  A. Riggs for his work on this.
1139
1140* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
1141  checksum check for the downloaded wx sources.
1142
1143* Fix a lot of the compiler warnings when building with clang.
1144
1145* doc/manual.sgml: Add missing quantities to the list documented as accepted by
1146  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
1147  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
1148  mentioned in list of the units that can be set for them); COUNT (missing
1149  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
1150  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
1151
1152* Test suite: Improve test coverage for cavern.
1153
1154Changes in 1.2.10 (2014-01-15):
1155
1156* aven: Fix assertion if two mouse buttons are held down at the same time.
1157  If dragging with more than one mouse button held down, releasing one causes
1158  another which is still held down to take effect.  Reported by Brian
1159  Clipstone.
1160
1161* aven: If we fail to start the external editor when the user clicks on an
1162  error or warning from cavern, show an error box.
1163
1164* aven: If the survey has a title, add it as a top-level <title> element to
1165  exported SVG files.
1166
1167* aven: Escape '<', '>', and '&' in labels in exported SVG files.
1168
1169* aven: In GPX export, set the <time> element to the datestamp from the 3d
1170  file.
1171
1172* aven: Don't try to write the title if it isn't set or is empty when exporting
1173  GPX files.
1174
1175* aven: Don't bother looking up the printer page setup info when exporting.
1176
1177* (Microsoft Windows version): aven: Fix crash on "File->Print" or
1178  "File->Export" under Windows XP, reported by Brian Clipstone.
1179
1180* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
1181  encoded filename which could occur if run without being asked to load a file
1182  on startup.
1183
1184* (Microsoft Windows version): aven: Compile with optimisation on.
1185
1186* img library, aven: Although processed CMAP data files are often referred to
1187  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
1188  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
1189  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
1190  continue to do so in case anyone is relying on it, but also check for the
1191  other extensions.
1192
1193* img library: Add new "datestamp_numeric" field to struct img giving the
1194  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
1195  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
1196  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
1197  timezone wrong.
1198
1199* img library: Fix my_strcasecmp() to handle top-bit set characters better.
1200
1201* cavern: Fix NULL pointer dereference when processing Compass DAT file without
1202  'SURVEY DATE:'.
1203
1204* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
1205
1206* doc/manual.sgml: Note the station length limit Smaps used.
1207
1208* Fix some compiler warnings if built with glibc's fortify source feature
1209  enabled.
1210
1211Changes in 1.2.9 (2014-01-08):
1212
1213* Document --3d-version in cavern man page and the manual.
1214
1215* aven: Fix compilation error in movie export code with recent libavi.
1216
1217* aven: Fix warning on stderr when export a movie as MPEG.
1218
1219* img library: In non-hosted mode, don't define GETC and PUTC if they're
1220  already defined, to allow easy overriding with getc_unlocked() and
1221  putc_unlocked() (which are significantly faster on Linux).
1222
1223* img library: In non-hosted mode, check that int is at least 32 bits,
1224  and if not, use long.  In practice, platforms with 16 bit int are mostly
1225  obsolete, but it's not hard to be portable here.
1226
1227* img library: Add test that img.c and img.h compile in non-hosted mode
1228  (regression test for issue fixed in 1.2.8).
1229
1230* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
1231
1232* Update translations from launchpad and from existing similar messages.
1233
1234* Fix some compiler warnings.
1235
1236Changes in 1.2.8 (2013-10-29):
1237
1238* cavern: Fix handling of anonymous wall stations ('..' by default) to
1239  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
1240  Holder.
1241
1242* cavern: Tweak .err file output not to lose the space in front of certain
1243  statistics when the value gets large.
1244
1245* cavern: Eliminate redundant progress message when solving simultaneous
1246  equations.
1247
1248* aven: Add a format drop down to the export dialog, and only show fields which
1249  are meaningful and supported for the currently selected export format.  The
1250  format defaults to that used most recently.  The "Elements" and "View" boxes
1251  have been swapped in the print and export dialogs as that layout works much
1252  better when the "View" box is hidden.
1253
1254* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
1255  - now works again.  Reported by Anthony Day.
1256
1257* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
1258  this release the projection which the survey coordinates are in defaults
1259  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
1260  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
1261  projection string.  The ability to specify this projection in a better
1262  way is coming soon.
1263
1264* aven: New export options "Origin in centre" and "Full coordinates" - the
1265  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
1266
1267* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
1268  time ago, so update references.
1269
1270* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
1271  with wxMSW 2.9.5.  Reported by Brian Clipstone.
1272
1273* aven: Make right click in an empty presentation mark the current position and
1274  open it to edit, instead of crashing.
1275
1276* aven: Update movie export code to work with latest libav API.  Reported by
1277  Sebastian Ramacher.
1278
1279* aven: Improve reporting of errors during the process of exporting a movie.
1280
1281* aven: Don't try to close the movie if we aren't producing one.
1282
1283* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
1284
1285* aven: Fix to build with wxMSW 2.9.5.
1286
1287* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
1288
1289* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
1290  ago, so add a new --skencil option to specify this output format.  The old
1291  name (--sketch) is still recognised for compatibility.
1292
1293* cad3d: Make --marker-size work for Skencil and SVG output.
1294
1295* dump3d: Make --show-dates option show dates for XSECT.
1296
1297* img library:
1298
1299  + Fix to work once more when used outside of Survex (missing definition of
1300    max() macro and a bad call to free() in img_close() for a file opened for
1301    reading).
1302
1303  + Use lround() instead of round(), and make the tests around whether we use
1304    the library function or the our fallback implementation saner.
1305
1306  + Fix // comments in C code for portability to pre-C99 compilers which don't
1307    support these as an extension.
1308
1309  + Can now be compiled as C++ as well as as C.
1310
1311* (Microsoft Windows version): The installer is now built with a newer version
1312  of Innosetup, and includes translations for all the languages which Survex
1313  itself has any translations for.
1314
1315* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
1316
1317* Minor translation updates.
1318
1319* tests/Makefile.am: Distribute files for "normal_bad" testcase.
1320
1321Changes in 1.2.7 (2013-07-27):
1322
1323* Add support for anonymous stations, which are indicated by one, two or three
1324  separator characters - with the default separator of '.', that means '.',
1325  '..', and '...' are anonymous stations.  Single separator ('.' by default)
1326  is an anonymous non-wall point, double separator ('..' by default)
1327  is an anoymous wall point at the end of an implicit splay), and triple
1328  separator ('...' by default) is an anoymous point (with nothing special about
1329  the leg).  A new *alias command allows '-' to be mapped to '..' for
1330  compatibility with pocket topo: *alias station - ..
1331
1332* New version 8 of the 3d format:
1333
1334  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
1335
1336  + New explicit file-wide flag for 'this is an extended elevation', rather
1337    than modifying the survey title to indicate this.
1338
1339  + The survey prefix is often unchanged from one leg to the next, so use a
1340    spare flag to compactly indicate when there's no label change.
1341
1342  + The data style of each leg is now stored.
1343
1344  + The "processed at" time is stored as seconds since 1970 rather than a
1345    human-readable string.
1346
1347  + Since 3d v8 features significant changes to the format, the format
1348    documentation for v7 and earlier has been split off into 3dformat-old.htm.
1349
1350* img library:
1351
1352  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
1353
1354  + Handle .pos files containing unnamed stations - don't suck the next line in
1355    as the station name, and set img_SFLAG_ANON for them.
1356
1357  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
1358    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
1359    elevation, in place of appending " (extended)" to the title.  Internally we
1360    still append this to the title (and remove it upon reading) when writing
1361    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
1362    explicitly in the file.
1363
1364  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
1365
1366* aven:
1367
1368  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
1369    now, and the wx developers consider even 2.8 to be rather long in the
1370    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
1371    formally dropping support for older versions allows a number of workarounds
1372    to be removed from the aven source code.  Also, features deprecated in
1373    wxWidgets 2.9 are no longer used in our code.
1374
1375  + Don't run incremental search on every key-press, as on a slow machine the
1376    short initial search(es) will take a while but not be useful.  Instead only
1377    actually run the search when we're told there are no more key-presses
1378    queued up.
1379
1380  + Implement support for including cross-section information in exported SVG
1381    and DXF files (ticket#4).  The DXF export is untested currently.
1382
1383  + Show splay legs faded by default, with menu options to hide them or show
1384    them like other legs.
1385
1386  + Speed up loading a .3d file with cross-sections by using a map to convert
1387    station names to positions.
1388
1389  + In the cavern log window, don't highlight a file:linenumber if there's no
1390    message after it, which avoids highlighting the "Included from" lines
1391    wrongly.
1392
1393  + Fix not to crash when trying to report an error while starting up.
1394
1395  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
1396    the OS X standard shortcut Shift-Command-F (previously we used F11, but
1397    that's used by the desktop).
1398
1399  + Add checks for errors when reading the font file.
1400
1401  + Remove useless extra quoting when invoking vim to show the location of an
1402    error from cavern.
1403
1404  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
1405
1406  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
1407    in the dialog in sync.
1408
1409* cavern:
1410
1411  + Demote errors about invalid dates to warnings, since we've accepted *date
1412    for ages without any checks on the value, and so existing datasets
1413    probably contain invalid dates and dates in other formats.  (ticket#19)
1414
1415  + New *alias command allows '-' to be mapped to '..' for compatibility with
1416    pocket topo: *alias station - ..
1417
1418  + We want to warn if there's a clino reading which it would be impossible to
1419    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
1420    read "93" (it's probably a typo e.g. for "39").  However, the gradient
1421    reading from a topofil is typically in the range 0 to 180, with 90 being
1422    horizontal.  Really we should allow the valid range to be explicitly
1423    specified, but for now we infer it from the zero error - if this is within
1424    45 degrees of 90 then we assume the instrument can read between 0 and 180
1425    degrees.
1426
1427  + If the survey isn't all connected, still run survey tree checks and report
1428    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
1429    Dixon for the report which highlighted this issue.
1430
1431  + Report a warning if *begin SURVEY has a separator character in SURVEY.
1432
1433  + Report column numbers as well as line numbers for some cavern errors and
1434    warnings.
1435
1436  + Adjust width of node stats table to fit longest count when there are more
1437    than 9999 of a particular order of node.
1438
1439  + If the argument to *include has an opening double quote but the closing
1440    double quote is missing, then skip trying to open the file.
1441
1442  + Move "Station X referred to just once" warning after non-existent survey
1443    check - if both fire, the non-existent survey error is likely to be more
1444    relevant.
1445
1446  + We no longer follow an error for a bad reading in passage data with a bogus
1447    "End of line not blank" error, but instead check the remaining readings on
1448    the same line.
1449
1450  + We no longer follow an error about OMIT for a required reading with a bogus
1451    "End of line not blank" error.
1452
1453  + Report an error if the scale factor in *calibrate is zero - it doesn't make
1454    sense and probably means someone reversed the arguments to *calibrate.
1455
1456  + Report the parent include files starting from the outermost, as that's more
1457    logical when there are multiple levels involved.
1458
1459  + If we were expecting a numeric field and instead get something which starts
1460    with '+', '-', or '.' but which isn't a number, then fix the error to
1461    include that character in the token reported.
1462
1463  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
1464    first item.
1465
1466* cad3d: Check for errors from img_rewind() and report them.
1467
1468* dump3d:
1469
1470  + Build, install and package dump3d as standard - it's useful for grabbing
1471    info from 3d files in scripts.
1472
1473  + Add --show-dates option.
1474
1475  + Show only 2 decimal places on coordinates and passage dimensions.
1476
1477  + Report the data style of legs.
1478
1479  + Report if the file is an extended elevation.
1480
1481  + Report img_STOP as STOP rather than CODE_0xffffffff.
1482
1483* Test suite:
1484
1485  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
1486    expected output so it passes reliably.
1487
1488  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
1489    'Deleted' stations upon failure are the more natural way round.
1490
1491  + Add more testcases, expand some existing testcases, and add expected output
1492    for more.
1493
1494* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
1495  appropriate C and C++ compilers to use, and link mingw build statically to
1496  avoid needing the libgcc DLL (which newer GCC seems to have by default).
1497
1498* (Unix version): When determining the character set for command-line tools,
1499  check environmental variable LANG after LC_ALL and LC_CTYPE.
1500
1501* When determining the language, check environmental variable LC_ALL before
1502  LC_MESSAGES and LANG (but after SURVEXLANG).
1503
1504* If we don't find the message file, only give an error if it was specified
1505  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
1506  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
1507  settings.
1508
1509* There are a handful of hard-coded English message strings for reporting
1510  errors trying loading message files, etc.  These are all now ASCII, as if we
1511  fail trying to open a message file, it's more likely the encoding isn't
1512  set correctly.
1513
1514* Prune strings we are no longer using and are probably unlikely to use again
1515  into a new file po_codes_dead, so that translators don't get presented with
1516  them to translate.
1517
1518* Merge lots of translation updates.  Most translations are now complete or
1519  close to complete.
1520
1521* Add start of Indonesian translation from Arief Setiadi Wibowo.
1522
1523* Fix various compiler warnings when building from source.
1524
1525* Include scripts gdtconvert and gen_img2aven in the source distribution.
1526
1527Changes in 1.2.6 (2012-02-23):
1528
1529* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
1530
1531* (Microsoft Windows version): Include JPEG images for aven in the installer
1532  package (ticket#35).
1533
1534* cavern: If we have a reference to a station in a non-existent survey, give a
1535  helpful error rather than saying the station hasn't been exported from the
1536  survey.  (Bug reported by Martin Green via email)
1537
1538* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
1539  Kahler.
1540
1541* findentrances: Add findentrances utility from Olaf Kahler which produces a
1542  .gpx file with waypoints for entrances.  This needs libproj so is disabled
1543  by default for this release - to enable it install the development stuff for
1544  libproj and build survex with:
1545
1546      make FINDENTRANCES=findentrances
1547      make install FINDENTRANCES=findentrances
1548
1549* dump3d: Add support for showing img_ERROR_INFO items.
1550
1551* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
1552
1553* Incorporate a French translation from launchpad I'd previously copied the
1554  English version of by mistake.  Attempt to correct mistranslation of "survey
1555  file".
1556
1557Changes in 1.2.5 (2012-01-03):
1558
1559* aven:
1560
1561  + The survey tree in the left panel is now in sorted order once more.
1562
1563  + No longer fails with an assertion if used for a long time (we were leaking
1564    an OpenGL list each time one had to be regenerated).
1565
1566  + Now builds with newer FFmpeg library.
1567
1568  + Draw measuring line in front of the indicators rather than behind them.
1569
1570  + Loading a new file (or reloading the current one) no longer invalidates
1571    the OpenGL lists for the compass and clino, so will be a fraction faster.
1572
1573* Improve handling of attempts to look up translated messages before the
1574  message subsystem is fully initialised (which only happens if there's an
1575  error early on).
1576
1577* Improve the survex(7) man page text, and fix it to be marked as section 7 in
1578  the man page source as well as in the filename.
1579
1580Changes in 1.2.4 (2012-01-01):
1581
1582* aven:
1583
1584  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
1585    initialised, which doesn't cause problems in some machines, but causes aven
1586    to abort on others.  This is now fixed, and there's a check in place to
1587    help avoid similar issues in future. (ticket#34)
1588
1589  + Always use metres or feet for the depth colour key, and chose a consistent
1590    precision by looking at the depth range. (ticket#30)
1591
1592  + Show the depth units below the colour bar rather than after every value.
1593
1594  + When zooming way in, stay in metres rather than switching to cm.
1595
1596  + On the scale bar, say “1 mile” rather than “1 miles”.
1597
1598* Translation updates for Catalan, French and Slovak.
1599
1600Changes in 1.2.3 (2011-12-31):
1601
1602* Fix to build with wxWidgets 2.9.2.
1603
1604* (Mac OS X version):
1605
1606  + Processing .svx files from aven now works.
1607
1608  + Remove spurious blank lines from the licence text in "Get Info".
1609
1610  + Don't create the help menu at all, as it is empty (because the "About"
1611    entry goes elsewhere) and sometimes seems to appear in the UI.
1612
1613  + INSTALL.OSX: Update to reflect current status.
1614
1615* aven:
1616
1617  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
1618
1619  + Improvements to text plotted on the survey pane:
1620
1621    - Support plotting Unicode character points > 256 by lazily loading the
1622      data for them from the font file and plotting them with a direct call to
1623      glBitmap(), which is slower but doesn't require a display list per
1624      character.
1625
1626    - Adjust the spacing from fixed width to putting a one pixel gap either
1627      side of each one character (so two between adjacent glyphs).  Mostly this
1628      reduces the horizontal width, but it adds a pixel for characters like "m"
1629      and two in a few cases.
1630
1631    - Fix .pixelfont file generation to correctly handle characters wider than
1632      8 pixels.
1633
1634  + Fix expected cross shape so don't always reject using texture mapping to
1635    draw crosses.
1636
1637  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
1638    as those consisting of just one.  Previously we would trip over the empty
1639    tube later.  Such tubes can for example be created by extend if a splay shot
1640    is the start or end of a tube.
1641
1642  + Make the green colour used for entrances in the survey tree the same
1643    (slightly darker than before) green used for the entrance blobs.
1644
1645  + Report the version of the library we're actually running with if built
1646    against wx >= 2.9.2.  Make it clear that the version reported is the
1647    version *built* with for wx < 2.9.2.
1648
1649* extend:
1650
1651  + Copy the end markers for passage tubes.
1652
1653  + Preserve left and right data for tubes (previously they were set to -1.0
1654    which means "no info").
1655
1656* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
1657  was no longer used - it certainly is!
1658
1659* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
1660  messages, and curly single right quote instead of straight ASCII apostrophe.
1661  Fall back to using straight ASCII versions if we can't represent them in the
1662  current character set.
1663
1664* Translation updates for Catalan, French, Slovak and Spanish.
1665
1666* Test suite:
1667
1668  + Add test coverage for interleaved diving data.
1669
1670  + Add testcase for diving data with topofil-style distance.
1671
1672Changes in 1.2.2 (2011-10-06):
1673
1674* aven:
1675
1676  + Replace the textured-mapped font drawing with an approach based on
1677    glBitmap.  This doesn't suffer from the character alignment issues which
1678    the textured-mapped fonts had, and is actually significantly faster on some
1679    machines.  The current font used is (mostly) fixed-width, but this isn't an
1680    inherent limitation - it was just the easiest font data to convert to a
1681    usable format.
1682
1683  + Fix assertion failure due to rounding differences on loading certain .3d
1684    files.  (ticket#26)
1685
1686  + Fix assertion failure when turning on 3D passages if they stick out higher
1687    or lower than any station.  (ticket#29)
1688
1689  + Fix grid not to disappear when blobs are turned on and blobs are drawn
1690    using lines.
1691
1692  + If a degree sign isn't available in the character set in use, transliterate
1693    it to 'dg' rather than skipping it.
1694
1695  + Fix message which should have been a degree sign but got lost in the format
1696    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
1697    that bearings in the status bar now have a degree sign after them if they
1698    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
1699
1700  + Fix print dialog to calculate the scale required for "One page" right
1701    before it calculates how many pages are required, so we don't end up
1702    something other than 1x1 being shown when the user changes settings.
1703
1704  + Update the calculations for picking a scale and for deciding how many
1705    pages are needed to take into account the change in info box height made
1706    in 1.2.1.
1707
1708Changes in 1.2.1 (2011-10-04):
1709
1710* Translation updates for US English.
1711
1712* aven:
1713
1714  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
1715    it now shows colours for dates and errors as well as depths.
1716
1717  + In the colour key for "colour by date", change "No info" to "Undated".
1718
1719  + Remove the dark grey background from the colour key and just put a single
1720    pixel black border around the colours.  This is more in keeping with the
1721    other controls, and means the colours are now on a black background so more
1722    visually similar to the survey legs.
1723
1724  + Move the colour key's "Undated"/"Not in loop" entry down a little to
1725    improve the appearance.  Make each section a pixel taller.
1726
1727  + Allow "Colour by X" to be selected even if there's no data for X or only a
1728    single value of X used (the colour key is much smaller in these cases, and
1729    does still provide some useful information).
1730
1731  + Fix incorrect calculation of depth colouring for survey legs which straddle
1732    a depth band boundary.
1733
1734  + The scale bar, compass, clino, and colour key now all have right click
1735    menus which allow related actions to be performed (especially handy in
1736    full-screen mode).
1737
1738  + Improve the font used on the survey pane - it now contains the '-'
1739    character (so the clino now shows negative angles as negative, and dates
1740    in the colour key are now hyphenated).  Also the spacing and alignment
1741    are a little better, though still not perfect.
1742
1743  + PLT file export now handles spaces and control characters in station names
1744    by escaping them with '%' as in URLs.
1745
1746  + Pressing "Enter" on a station in the tree control now centres the view on
1747    that station.
1748
1749  + The scale bar is now cached in an OpenGL display list since it often gets
1750    redrawn exactly the same - for example, when rotating, panning, etc.
1751
1752  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1753    then forces a refresh of the survey pane.  This is intended as a debugging
1754    aid - if pressing F5 changes the display at all then there's a missing case
1755    where a list should have been invalidated (please report if you find such
1756    a case as it is a bug).
1757
1758  + We now automatically track which OpenGL display lists need to be
1759    invalidated on window width or height changes.
1760
1761  + Increase scale bar maximum width from 65% of the window width to 75% as it
1762    was in 1.0.x (except that if that would overlap the clino we now reduce
1763    that proportion down until it reaches 50%).  Make the limit of zooming in
1764    the same as in 1.0.x.  (ticket#23)
1765
1766  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1767    the application was fullscreen (the dialog got opened under the main
1768    window!)  To work around this, aven would switch out of full screen mode
1769    temporarily while showing a dialog.  This case works properly with recent
1770    wxGTK, so disable our workaround with versions we know work.  Also, apply
1771    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1772    as there's no reason to think we need it for other platforms.
1773
1774  + Grey out the "View North" action when we're already viewing North, and
1775    similarly for other compass points.
1776
1777  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1778    info in the "About" dialog.
1779
1780  + Fix to set the correct filename on the root of the survey tree - previously
1781    the filename of the previous file loaded was used!
1782
1783  + The movie export code now works with newer versions of the FFmpeg libraries
1784    as well as still working with older versions.
1785
1786  + Fix mixed up messages - the print dialog now says "View" on the left
1787    subgroup of controls rather than some unrelated message.
1788
1789  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1790    field which gives the bearing and reduce the height on the info box by the
1791    removed field, so it's now 3cm for plans and elevations, as for extended
1792    elevations.  Report the tilt angle for tilted elevations which it seems has
1793    been missing for ages (it's not in recent 1.0.x either).
1794
1795  + Tweak the exact positioning of informational text on printouts to look
1796    nicer and make better use of the available space.
1797
1798  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1799    dialog.
1800
1801  + Make the sign of the tilt angle for printouts consistent with the sign
1802    shown by the "clino" in the survey pane.
1803
1804  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1805    and similarly for the "Elevation" button.
1806
1807  + (Microsoft Windows version): Sort out appearance of custom cursors.
1808
1809  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1810
1811  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1812    you can't get out again easily, so add code to explicitly check for F11
1813    being pressed and toggle full screen.
1814
1815* (Linux version): Fix the RPM .spec file for where man pages now get installed
1816  and package aven.svg and the vim support files.  (Fixes from James Begley)
1817
1818* "make check" now performs several checks on the translation files.
1819
1820* More messages are now available to be translated.
1821
1822* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1823  the message handling changes in 1.2.0.
1824
1825* Fix warning when compiling with GCC.
1826
1827* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1828  sudo for installing on Unix.
1829
1830* In the manual, replace the instructions for building from source with a
1831  pointer to the clearer instructions in INSTALL.
1832
1833* In the manual, make it clear that installing with administrator rights
1834  also applies to newer platforms than XP.
1835
1836* doc/TODO.htm: Update.
1837
1838Changes in 1.2.0 (2011-09-20):
1839
1840* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1841  English.
1842
1843* tests/smoke.tst: aven no longer requires an X display for --help or
1844  --version, so replace skip of this check with a check that this remains the
1845  case.
1846
1847* We now use the standard .po and .pot file formats for storing translations
1848  (rather than the Survex-specific messages.txt format), and then translate
1849  these into Survex's .msg format.
1850
1851* (Unix version): Move survex man page to section 7 (since it isn't documenting
1852  an actual command).
1853
1854* (Unix version): Write each generated man page to a temporary file, then
1855  atomically rename, to avoid leaving an empty or partial man page behind if
1856  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1857  recurrence of that).
1858
1859* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1860  than /usr/doc/survex.
1861
1862* aven:
1863
1864  + Fix handling of accented characters in the survey pane.
1865
1866  + Aven icon redrawn in SVG format - it's now a vector image which looks
1867    nicer at larger sizes.
1868
1869  + Explicitly request double-buffering, which seems to be needed for systems
1870    with GLX >= 1.3.
1871
1872  + Fix crash while trying to load certain .3d files.
1873
1874  + Movie export code updated to work with more recent versions of FFmpeg.
1875    Currently this is disabled in Microsoft Windows builds, pending getting the
1876    required libraries set up for building releases.
1877
1878  + Reporting of errors during movie export improved.
1879
1880  + Force playback speed to "x1" during movie export.
1881
1882  + Use stock IDs for buttons where appropriate - such buttons may now be
1883    rendered with icons on some platforms.
1884
1885  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1886    ISO8859-1).
1887
1888  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1889    as it's no longer required with modern versions.
1890
1891  + Don't redraw the survey on every mouse movement in the survey pane unless
1892    the measuring line is (or just was) active.  (ticket #17)
1893
1894* cavern:
1895
1896  + Drop "non-fatal" from the report of how many errors there were at the end
1897    of the run - it just confuses users - we won't even get here if there's a
1898    fatal error!
1899
1900  + Add --3d-version option to allow the user to specify the version of the 3d
1901    format to output.  (ticket#21)
1902
1903* img library:
1904
1905  + Make the highest and lowest valid values for img_output_version available
1906    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1907
1908* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
1909  volume actually gets mounted.  Fix URL for downloading wxWidgets.
1910
1911Changes in 1.1.16 (2011-05-16):
1912
1913* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1914  Portuguese, and US English.
1915
1916* Use horizontal ellipses character rather than '...' and right arrow character
1917  rather than '->' where these characters are available.
1918
1919* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1920  GNU ld --as-needed (Debian bug #615781).
1921
1922* img.c:
1923
1924  + Fix code typo for IMG_API_VERSION == 0 case.
1925
1926  + Fix code typo in code used when IMG_HOSTED isn't defined.
1927
1928* doc/TODO.htm: Remove entries which have now been done.
1929
1930* (Microsoft Windows version): aven: We now include all the available
1931  translations for messages from wxWidgets, which means that standard widgets
1932  will appear translated where available even if Survex messages aren't
1933  translated.
1934
1935Changes in 1.1.15 (2010-10-15):
1936
1937* aven:
1938
1939  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1940    follow terminology in manual and elsewhere.  Fixes ticket#15.
1941
1942  + When displaying output from cavern, don't update the window after every
1943    line, but only when we don't have data from cavern pending.  Hopefully
1944    addresses ticket#12.
1945
1946  + If we aren't using GL_POINTS for blobs, draw them using a series of
1947    abutting lines rather than with gluDisk which is faster and gives a
1948    consistent shape.
1949
1950  + Check whether blobs and crosses actually render correctly as points/point
1951    sprites, and if they don't, fall back to drawing them with lines.  The
1952    best method is cached on disk, and rechecked automatically if the graphics
1953    hardware is changed or the drivers upgraded.
1954
1955  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1956    though, so we still enable USE_FNT by default).
1957
1958  + Don't offer "All files" wildcard in presentation save dialog.
1959
1960  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1961    more places.
1962
1963  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
1964    when running cavern from aven.  Fixes ticket#11.
1965
1966* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1967
1968* diffpos: Handle files with duplicate labels in better - extend generates
1969  duplicate labels when it breaks a loop.
1970
1971* Enable eswap-break testcase now that diffpos handles duplicate station names.
1972
1973* New v7 of .3d format which stores survey dates as number of days since
1974  January 1st 1900, so we now support dates from 1900-2078 (rather than
1975  1970-2037) with a smaller file size.  The img API is now versioned - you
1976  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1977  gives the survey dates in days in days1 and days2 instead of as time_t
1978  values in date1 and date2.  Fixes ticket#14.
1979
1980* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1981  former has been the canonical name for some time, with www.survex.com just
1982  redirecting to it.
1983
1984* (Unix version): Use unlocked file I/O if available, which can be much faster
1985  in some cases (we don't need the locking as we don't do multithreaded file
1986  I/O).
1987
1988* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1989  headers.
1990
1991* (Mac version): buildmacosx.sh now works again.
1992
1993* Most tests weren't actually running any testcases (looks like a sh
1994  portability issue).  This is now fixed, and fortunately all tests still pass.
1995
1996* Include the extra .isl translation files for Innosetup in the source archive.
1997
1998Changes in 1.1.14 (2010-07-26):
1999
2000* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
2001
2002* aven:
2003
2004  + After processing survey data, if there were warnings or errors, add a
2005    "Rerun" button to allow easy reprocessing after fixing problems.  If there
2006    were only warnings, also add an "OK" button to allow moving on to viewing
2007    the processed survey data (fixes ticket#13).
2008
2009  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
2010
2011  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
2012    not the ': ' after), and to make the title for the terminal the
2013    warning/error message.  Avoid false positives by checking that '<line>' is
2014    a number.
2015
2016  + Don't double escape the contents of href and target in links in the cavern
2017    log window.
2018
2019  + Improve handling of the splitter window, fixing behavioural glitches in
2020    various cases.
2021
2022  + Highlight stations matching any current search when a file is loaded.
2023    (ticket#9)
2024
2025  + (Mac version): Fix build issue due to Mac OS X polluting the global
2026    namespace with its own "Point" class.
2027
2028  + (Unix version): The Gnome print dialog has its own preview window so
2029    suppress ours if using the Gnome one.
2030
2031  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
2032
2033  + (Microsoft Windows version): Fix handling of a double-click on the survey
2034    tree when built with wxWidgets >= 2.8.11.
2035
2036* cavern: Report relevant file and line number for three warnings which didn't
2037  give them before.
2038
2039* (Unix and Mac versions): configure: Update the wx-config probing code -
2040  wxmac-config etc aren't present with newer wxWidgets versions so there's no
2041  point looking for them now.
2042
2043* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
2044  for easy installation.  Update it to work with the latest Survex versions
2045  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
2046  private wxWidgets, use 2.8.11 not 2.7.0-1).
2047
2048* manual:
2049
2050  + Correctly capitalise "GTK".
2051
2052  + Note that on Linux we only regularly test builds with the GTK+ version
2053    (change taken from 1.0).
2054
2055* Fixed the cad3d man page, which was an empty file in 1.1.13.
2056
2057Changes in 1.1.13 (2010-06-16):
2058
2059* Say "wxWidgets" instead of "wxWindows" consistently.
2060
2061* img.c: Fix small memory leak (filename_opened member).
2062
2063* cad3d, aven: Fix export to SVG when a label contains a '%' character.
2064
2065* aven:
2066
2067  + wxWidgets 2.6.0 or newer is now required.
2068
2069  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
2070    work but hasn't been tested recently (all packaged versions of wxWidgets
2071    seem to be Unicode now).
2072
2073  + Fix potential uses of uninitialised variables which may have been causing
2074    occasional glitches when loading a file on start-up.
2075
2076  + Improvements to the handling of the font used for plotting labels and other
2077    text on the survey pane:
2078
2079    - Loading the font file is more efficient.
2080
2081    - Character spacing is improved.
2082
2083    - Default font is now anti-aliased.
2084
2085  + "About" dialog:
2086
2087    - Add "Copy" button to copy the system info to the clipboard for easier
2088      bug reporting.
2089
2090    - List OpenGL extensions last, since there are usually lots of them with a
2091      modern gfx card.
2092
2093    - Fix 100% CPU usage while the "About" dialog is open.
2094
2095  + Processing .svx files:
2096
2097    - Passing a .svx file on the command line now works better.
2098
2099    - Put the survey data log window in a splitter in the usual frame rather
2100      than opening a separate frame for it.
2101
2102    - Auto-scroll the log window until we've reported a warning or error.
2103
2104    - Fix small memory leak.
2105
2106  + The presentation filename now defaults to using the basename of the
2107    currently loaded dataset, but we always prompt before we first save with
2108    such a name.
2109
2110  + Reduce memory usage when saving a screenshot.
2111
2112  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
2113    persist the window size (and maximised or fullscreen state) between
2114    invocations.
2115
2116  + Fix reporting of OpenGL errors.
2117
2118  + Fix glitches when tilting while looking East.
2119
2120  + Added Portuguese and Slovak translations of wxWidgets messages.
2121
2122* Documentation:
2123
2124  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
2125
2126  + Drop the "alternative manual formats" self-extracting zip file - people
2127    will generally just want one of the formats, so downloading several
2128    together isn't very useful.
2129
2130  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
2131
2132  + GPL.htm: Replace HTML version of licence with a link to the version on
2133    the FSF website.
2134
2135  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
2136    low level to be of interest to non-developers, and developers can look at
2137    the source code.
2138
2139* (Unix version): configure: New preferred name for specifying wx-config script
2140  is WX_CONFIG.  WXCONFIG still supported for compatibility.
2141
2142* (Linux version): Source RPM package dropped as you can just build an RPM
2143  package from the source tarball.
2144
2145* (Microsoft Windows version): The installer is now created with a newer
2146  version of InnoSetup, which gives a 10% smaller download.
2147
2148Changes in 1.1.12 (2007-02-07):
2149
2150* aven:
2151
2152  + Remember the window size or maximised/fullscreen state between invocations.
2153
2154  + Add options dialog to "Export" similar to the one for "Print".
2155
2156  + The "number of pages required" in the print dialog now updates when you
2157    change what is to be shown (underground legs/surface legs/station
2158    names/crosses).
2159
2160Changes in 1.1.11 (2006-11-25):
2161
2162* Updated Czech, Spanish, and Slovak translations.
2163
2164* (MacOS X version): Assorted OS X specific tweaks and fixes.
2165
2166* aven:
2167
2168  + Pick a smaller and clearer font for labels.
2169
2170  + Fix character spacing.
2171
2172  + Tweak display of bearing and elevation angles to look nicer with
2173    proportional fonts.
2174
2175  + Use the title from the 3d (or plt, etc) file for the window title
2176    rather than the filename.
2177
2178  + Show distances to 2 decimal places rather than the nearest integer.
2179
2180  + Only consider underground legs when calculating the depth bands and
2181    depth colouring.
2182
2183  + Add "Colour by Error".
2184
2185  + Add entry for "white" in date and error keys.
2186
2187  + When setting the view to a single point, don't change the scale.
2188
2189  + If reloading the same file, don't change the view
2190
2191  + Fix filetypes selector in open dialog.
2192
2193  + Fix the charset we use for aven in certain cases.
2194
2195  + Call msg_init before using msg_lang or it won't ever be set!
2196
2197  + Pass wx the full language code to initialise the C library locale.
2198
2199  + Fix bug in generating prefix tree view which could lead to a bogus
2200    leading dot on some survey names (bug probably introduced in 1.1.10).
2201
2202  + "New Presentation" now ensures that the side panel is open
2203
2204  + Fix updating of cached opengl lists when the view is reset to the
2205    default.
2206
2207* Ignore LANG if it starts with a digit to avoid problems with bogus value for
2208  LANG which AutoCAD installation seems to set on MS Windows.
2209
2210* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
2211  specified.  Either/both can be set to ":".
2212
2213* dump3d: Report unknown (to dump3d) codes returned by img.
2214
2215* img library: Flag all stations as underground in the old "ASCII" .3d format.
2216
2217Changes in 1.1.10 (2006-07-14):
2218
2219* aven: Clicking on a survey name in the survey tree now highlights it in
2220  the map view.  Double-clicking zooms the view to show the clicked survey
2221  highlighted.  Clicking the root clears the highlighting and double-clicking
2222  the root restores the default view.  To expand/collapse a branch, click
2223  on the "[+]" or "[-]" icon to the left of the survey name.
2224
2225* aven: The measuring line can now measure to anywhere in plan or elevation
2226  view (not just to a station!)  In plan view the horizontal distance and
2227  bearing are shown, while in elevation view the vertical distance is shown.
2228
2229* aven: Moving the mouse over a station in the survey view now highlights
2230  that station in the survey tree (though it may not be visible if the
2231  survey(s) it is in aren't expanded).
2232
2233* aven: Clicking on a station to centre the view now moves the mouse pointer
2234  to the new location of the station (except on Mac OS X where this isn't
2235  allowed).
2236
2237* aven: Fix which presentation toolbar buttons are shown as depressed.
2238
2239* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
2240
2241* vim files are now installed with the correct paths (bug introduced in 1.1.9).
2242
2243Changes in 1.1.9 (2006-07-04):
2244
2245* (Unix version): Install desktop files for aven and svxedit contributed to the
2246  Ubuntu package by Phil Bull, and corresponding pixmaps.
2247
2248* Fix img to filter out cross-sections which don't match the subsurvey (if
2249  specified).  The API now returns img_XSECT_END to mark the end of a
2250  passage rather than setting a flag on the last img_XSECT of the passage.
2251
2252* Enhance integration with the vim editor - this can now colour .err files, run
2253  cavern from vim and parse error output, and run aven from vim.  Tweak the
2254  existing vim mode for .svx files to fix a few minor bugs and add support for
2255  the new "*data passage" style.
2256
2257* aven: fix drawing of the "blob" end of the measuring line on graphics cards
2258  which can't draw large enough blobs for us.
2259
2260* aven: sort out confusion about what encoding everything is in which means
2261  that the distance measured by the measuring line actually gets displayed
2262  and also fixes problems with empty menu items in non-English locales in
2263  some cases.
2264
2265* aven: redraw grey background after a menu is closed over the aven window
2266  with no survey loaded.
2267
2268* aven: fix bug which caused printing to crash (introduced in 1.1.8).
2269
2270* aven: avoid crash on some machines when opening "About" dialog before having
2271  loaded a survey.
2272
2273* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
2274
2275* (Unix version): aven: Fix character set handling of cavern output.
2276
2277* cavern: Report an error if a cross-section is specified for a station which
2278  doesn't exist.
2279
2280* Updated French and Italian translations.
2281
2282* (Unix version): aven: Fix "Can't open message file `en_US' using path
2283  `${prefix}/share/survex'" error.
2284
2285* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
2286  (doesn't affect Survex itself, but other applications which use img.c should
2287  update their copy).
2288
2289* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
2290  and later are caught by configure, whereas older wx versions are caught when
2291  trying to compile).
2292
2293Changes in 1.1.8 (2006.06.30):
2294
2295* Drop support for building with wxWidgets versions prior to 2.4.0
2296  (which was released on 2003-01-07).
2297
2298* aven: Printing through aven now uses settings from the "[aven]" section
2299  of print.ini, and support for hierarchical sections (using "like=")
2300  has been disabled.
2301
2302* aven: Change mouse actions to be compatible with those in Survex 1.0.
2303  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
2304  left drag is now smart about not rotating and zooming at the same
2305  time.
2306
2307* aven: Highlighting stations now happens as you type, and pressing
2308  "Enter" or clicking the "Find" button now pans and zooms to show the
2309  highlighted stations.
2310
2311* aven: Left-clicking away from a station now cancels measuring line.
2312
2313* aven: Setting view to North, South, East, or West is now animated like
2314  the tilt from plan to elevation.
2315
2316* aven: Fix presentation saving to also write "." for decimal points and
2317  presentation loading to accept either "." or ",".
2318
2319* (Unix version): aven: Add text for all toolbar items so that aven
2320  will work with the Gnome desktop preference for displaying toolbars as
2321  icons with text or just text (wxWidgets needs fixing first though).
2322
2323* (Unix version): aven: Remove the ability to detach the menu bar (yell
2324  if you actually used it and I'll restore it!)
2325
2326* aven: Add "all survey files" option to the "open file" dialog.
2327
2328* (MS Windows version): aven: Fix cursor keys to pan survey.
2329
2330* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
2331
2332* (MS Windows version): Fix installer to work on Windows 2000 or XP if
2333  run by an unprivileged user.
2334
2335* (MS Windows version): Upgrade to the latest version of InnoSetup (the
2336  installer builder we use) and include new installer translations for
2337  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
2338
2339* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
2340  translations of messages for wxWidgets (the GUI library we use).
2341
2342* aven: Disable "Highlight exported points" if there aren't any.
2343
2344* Updates to French translation from Michel Bovey.  Also updates to German,
2345  Italian, Catalan, Spanish, and Romanian translations.
2346
2347* (Unix version): test suite: fix smoke test to pass even without X running
2348  (it was meant to but the code had a bug).
2349
2350* aven: Check if OpenGL is available and exit cleanly with a helpful error
2351  if it isn't.
2352
2353* (Unix version): aven: Fix --help and --version to work without a working
2354  X display (provided it's built with wxWidgets 2.5.1 or newer).
2355
2356* aven: Automatically select the presentation tab of the notebook when the user
2357  selects "New Presentation" or "Open Presentation".
2358
2359* aven: Fix "Delete" in the presentation list to not get passed on (and so not
2360  reset to default view as well).
2361
2362* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
2363  empty.
2364
2365* aven: Fix Cursor Up and Down in the presentation list to move the highlight
2366  up and down instead of being passed on and moving the survey.
2367
2368* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
2369  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
2370  Safari 2.0.3, and InkScape 0.42.
2371
2372* aven: Put a 5mm border around exported SVG files to allow for station markers
2373  and non-zero width lines.
2374
2375* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
2376  was turned on.
2377
2378* aven: Actually close the file we're exporting which fixes problems with it
2379  not always being fully written.
2380
2381Changes in 1.1.7 (2005.10.18):
2382
2383* cavern: Add validity checking for dates in *date commands (with feature
2384  test in testsuite).  A date entered as just "year" or "year.month" now
2385  becomes a date range for the relevant period (previously it became a single
2386  date near the middle of that period).
2387
2388* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
2389  with MS Windows).
2390
2391* extend: Default output name for a file called input.3d is now input_extend.3d
2392  rather than just extend.3d (which was annoying if you wanted to extend
2393  several surveys in the same directory).
2394
2395* aven: OpenGL 2.0 always includes support for point sprites so rework
2396  our check for them to include that knowledge.
2397
2398* aven: Regenerate depth bar if user switches to/from metric units.
2399
2400* aven: Don't clear the "there" mark just because the mouse pointer has
2401  moved off a station.
2402
2403* aven: When processing a .svx file, put the resultant .3d file in the
2404  same directory (since that's where we then try to load it from).
2405
2406* aven: Fix labelling of date colouring on 32 bit platforms.
2407
2408* aven: If "colour by date" is on and we load a survey with no date info
2409  (or all surveyed on the same date) then set "colour by none".
2410
2411* aven: Make the error dialog modal and remove a signal handler once it
2412  has fired to prevent endless (or seemingly endless) cascades of error
2413  dialogs.
2414
2415* aven: Enforce a minimum object volume diameter of 1m to avoid problems
2416  if a survey file with only one station in is loaded.
2417
2418* aven: Fix problems with indicators disappearing when we're drawing
2419  blobs and/or crosses the slow (but always supported) way.  (Problem
2420  introduced in 1.1.6).
2421
2422* (Unix version): aven: Really stop setting extra toolbar margin when using
2423  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
2424  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
2425
2426* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
2427  we've been compiled with, and which GTK+/Motif version where appropriate.
2428
2429* (Unix version): Fixed build on Fedora Core 3.
2430
2431* documentation: Updates to 3d file format specification from Mike McCombe.
2432
2433Changes in 1.1.6 (2005.10.10):
2434
2435* (MS Windows version): Distribution is about a third smaller than 1.1.5
2436  (mostly because mingwm10.dll is no longer required).
2437
2438* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
2439  it, showing cavern's output in a window (with errors and warnings clickable
2440  to load the offending file into an editor), and then loading the resulting
2441  3d file.
2442
2443* aven: Added "Colour by Date" option.
2444
2445* aven: Disable "Colour by Depth" option if there's no elevation variation.
2446
2447* aven: Don't crash if trying to load a survey with no elevation variation.
2448  Instead turn off depth colouring.
2449
2450* aven: Export as HPGL added.
2451
2452* aven: Improved update of mouse coordinates and measuring line (thanks to
2453  Martin Green).
2454
2455* aven: Show the coordinates of either the mouse pointer or the nearest
2456  survey station to it (if there is one near enough).  Showing both was
2457  confusing and meant the status bar overflowed on smaller displays.
2458
2459* aven: When printing an extended elevation, don't show bearing and elevation.
2460
2461* aven: Don't lock "flat" surveys which aren't extended elevations - a
2462  flat survey with LRUD data isn't flat any more!
2463
2464* aven: When we have to draw blobs and crosses the slow way (because the
2465  graphics hardware doesn't support the fast way), draw them so that they
2466  should appear at the correct depth into the 3D scene instead of on top
2467  of everything else.
2468
2469* aven: Make "play presentation backwards" icon green to match the other
2470  presentation icons.
2471
2472* (MS Windows version): aven: Mouse clicks on the survey view now set the
2473  keyboard focus there.
2474
2475* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
2476
2477* (MS Windows version): aven: Fix redrawing of measuring line.
2478
2479* cavern: Store dates for img_XSECT.
2480
2481* cavern: Fixed small one-off memory leak if you specify -o more than once.
2482
2483* (Unix version): Check environmental variable LC_MESSAGES when deciding what
2484  language to use for messages.
2485
2486* (MS Windows version): "Print" on a 3d file now prints through aven rather
2487  than the separate printer driver (Unix has done this for some time).
2488
2489* Removed old printer drivers.
2490
2491* img library: When creating a 3d file, ignore img_XSECT if we've been asked
2492  to write a file format version which doesn't support it.
2493
2494Changes in 1.1.5 (2005.09.20):
2495
2496* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
2497
2498* aven: Make blobs round like they are in Survex 1.0.
2499
2500* aven: If the graphics drivers don't support drawing blobs using OpenGL
2501  point markers, fall back to drawing filled circles.
2502
2503* aven: If the graphics drivers support it, draw crosses as texture mapped
2504  OpenGL point markers which is much faster.
2505
2506* aven: Cross size increased to match Survex 1.0.
2507
2508* aven: We must update which blobs are displayed if display of surface or
2509  underground legs is toggled.
2510
2511* cavern: Fix handling of a *solve followed by survey data, none of which is
2512  attached to the previous data.
2513
2514* cavern: Fixed "No survey data" error when a *solve is followed by another
2515  *solve (or the implicit solve at the end of processing) with no data between
2516  them.
2517
2518Changes in 1.1.4 (2005.09.19):
2519
2520* aven: Added Aven's icon to the "About" dialog.
2521
2522* aven: Use localised character for the decimal point (e.g. "," in most
2523  continental European countries).
2524
2525* aven: Previously the survey tree would get focus and then take keypresses
2526  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
2527  operate on the cave, and transfer the input focus across when we do.
2528
2529* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
2530
2531* aven: Speed up intialisation by delaying creation of OpenGL lists until
2532  they're needed.
2533
2534* aven: Added Mark Shinwell's bounding box with shadow of the survey.
2535
2536* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
2537
2538* aven: Reworded "Restore Default Settings" as "Restore Default View".
2539
2540* (Unix version): aven: Set sensible default margins for printing and preserve
2541  any margin values the user specifies between runs (previously margins
2542  defaulted to 0 each time aven was run).
2543
2544* Documentation: Document *DATA PASSAGE in the manual.
2545
2546Changes in 1.1.3 (2005.09.07):
2547
2548* (Microsoft Windows version): Fixed build problems.
2549
2550* cavern: Allow OMIT character (-) for left/right/up/down.
2551
2552* aven: Remove an unnecessary menu separator.
2553
2554* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
2555
2556* aven: Make the tooltip for "Hide" show the number of found stations.
2557
2558* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
2559
2560* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
2561  when there's a presentation loaded.
2562
2563* aven: Make entrances green in side panel tree list to match green blobs used
2564  in cave view.
2565
2566* aven: Don't show surface labels if we're not showing surface data, etc.
2567
2568* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
2569  make "Space" the key for this.  Keep Return working "Stop Rotation" so
2570  existing users are happy, but don't advertise it.
2571
2572* aven: Normalise filename by adding any extension used, and use the normalised
2573  filename for file history and window title.
2574
2575* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
2576  as the toolbar buttons already have a sensible margin - the extra margin is
2577  only needed with GTK1.2.
2578
2579* aven: Fix handling of plumb legs in tube model.
2580
2581* aven: Fixed swapped L and R in tube model.
2582
2583* extend: Preserve UD cross-section information in extended elevation.
2584
2585* extend: Add new messages for John Pybus' enhancements.
2586
2587Changes in 1.1.2 (never formally released):
2588
2589* Added support for LRUD data in .svx files, in .3d files, and aven can
2590  now load and display it on screen and on printouts.  The ability to "fake"
2591  LRUD data in aven is gone for now but will reappear in some form later.
2592
2593* cavern: Removed support for writing Chasm's 3dx format.  We're going to
2594  fold any desirable missing chasm functionality into aven.
2595
2596* aven: Rearranged mouse actions as discussed on the mailing list.  Added
2597  cursors for each different mouse action to help the user learn what each
2598  does.  Also added cursors for the "compass" and "clino" as well as the
2599  scalebar to suggest to the user that they can be dragged to change the view.
2600
2601* (Unix version): aven: Don't segfault if LANG isn't a known language.
2602
2603* tests/smoketest.tst: If X windows is running, check that we can run aven
2604  with --help and --version.
2605
2606* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
2607  no results are listed for it.  This revealed that there was a "newline" test
2608  which should have been called "badnewline", and was a broken testcase too!
2609  Fixed all these problems.
2610
2611* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
2612  and omitted forward compass/clino readings in Compass DAT files.  Added
2613  a feature test for this to the testsuite.
2614
2615* It no longer makes sense to have an option not to build aven or to build aven
2616  without OpenGL so remove old machinery for this from configure and the
2617  sources.
2618
2619* (Unix version): configure: Check if "-lXxf86vm" is needed.
2620
2621* configure: Better output for strcasecmp test.
2622
2623* aven: Fix crosses to work much better.  Not a total fix - their position
2624  in the Z buffer isn't correct and they're rather slow to plot.
2625
2626* aven: Don't regenerate the hittest grid every time the mouse moves while
2627  animating, which solves the mysterious pausing effect (thanks go to Martin
2628  Green for spotting this!)  Also clear all the status bar coordinates when
2629  animating.
2630
2631* aven: Sort out clashing menu shortcuts in some languages.
2632
2633* aven: Fixed compilation problem on x86_64
2634
2635* SPUD: Pruned out stuff which has been done or which is not actually relevant
2636  to this branch.
2637
2638* Merge various changes from 1.0 branch:
2639
2640  + aven: Port over "printing from aven" functionality.
2641
2642  + aven: Port over "export as" functionality,
2643
2644  + Add David Loeffler's vim mode for .svx files.
2645
2646* aven: Fix check for whether a label is behind us in perspective view.
2647
2648* aven: Don't use an opengl list for drawing the indicators - we typically make
2649  a new list each time we plot them anyway.
2650
2651* Remove lingering traces of support for RISC OS and pre-386 MSDOS
2652
2653* aven: Set icon on non-Windows platforms too.  This means that with
2654  WindowMaker on Unix you get an icon on the AppIcon by default.
2655
2656* configure: Update wxWindows checks to handle newer wx versions.
2657
2658* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
2659  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
2660  for anyone building from CVS).
2661
2662* acinclude.m4: Quote macro name for fix autotools warning.
2663
2664* Documentation: "tilt up" is "'" not ",".
2665
2666* aven: Add support for mousewheels (to tilt the cave).
2667
2668* aven: Fixed twisted transitions to and from pitches in certain cases.
2669
2670* aven: Pick a sensible initial window size when the user's desktop is spread
2671  over more than one monitor (works best with wx2.5 or newer, but try to do
2672  better with wx2.4 or earlier as well).
2673
2674* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
2675  contents being visible before any survey is loaded.
2676
2677* aven: Allow a coloured texture to be used
2678
2679* aven: Don't initialise until we have data (to the user, this means the window
2680  is default colour (grey for most systems) not black until a survey is
2681  loaded).
2682
2683* aven: Fixed weird "shadowed" icons.
2684
2685Changes in 1.1.1 (2004-10-06):
2686
2687* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
2688  startup.
2689
2690* aven: Delay loading the bitmap for the "About" dialog until it is first
2691  needed.  We want start up to be as quick as possible.
2692
2693Changes between 1.0.32 and 1.1.0 (never formally released):
2694
2695* NOTE: Survex 1.1.X releases are development snapshots made available for
2696  the purposes of allowing wider testing and getting more user feedback.  Once
2697  the code has stabilised the version number will be raised to 1.2.0.
2698
2699* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
2700  you're using Windows 95 - these can be obtained from:
2701  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
2702
2703* aven: Solid passages - passage dimensions are currently inferred from
2704  the leg length (pretty effective as you can measure longer legs in
2705  larger passages).  Use of real LRUD data coming soon...
2706
2707* aven: Depth colouring is now continuously varying.
2708
2709* aven: Colour by depth can now be turned off (and there's the start of a
2710  framework for properly implementing colour by date, error, etc).
2711
2712* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
2713  match (? matches any character, * matches any number of characters).
2714
2715* aven: We now use the status bar for coordinates, distances, etc to make
2716  better use of screen space.
2717
2718* aven: Full screen mode (F11).
2719
2720* aven: Perspective view.
2721
2722* aven: Context sensitive cursor shape - needs more work.
2723
2724* aven: Mouse actions changed (hopefully they're now more natural, but
2725  you may find the change disorientating - feedback wanted on this).
2726
2727* aven: Added "presentations" which allow you to set up fly-through paths
2728  and load/save/run them.
2729
2730* aven: A presentation can be exported as a movie file.
2731
2732* aven: Added Save screenshot facility.
2733
2734* aven: Depth fogging option.
2735
2736* aven: Added Smooth Lines option.
2737
2738* aven: Added Textured Walls option.
2739
2740* aven: If a survey has surface legs but no underground legs, default to
2741  showing the surface legs.
2742
2743* cavern: Dates given to *date are now stored in the 3d file.
