1Changes in 1.2.41 (2019-07-10):
2
3* aven:
4
5  + (Microsoft Windows version): Fix error on startup in the pre-built version
6    of 1.2.39 and 1.2.40.  This is a recurrence of the same issue as affected
7    1.2.33 - this time I've patched out the unnecessary check in wxWidgets
8    which causes this problem so it shouldn't recur again.  Reported by
9    Brian Clipstone.
10
11  + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
12    as I don't have access to a Mac).  Hopefully fixed #101, reported by floho.
13
14Changes in 1.2.40 (2019-07-04):
15
16* aven: Draw the measuring line ring with an even shape.  Previously the exact
17  shape of the ring varied slightly depending on the exact coordinates, which
18  could be visually distracting once you noticed it.
19
20* We were casting a function pointer with a bool return type to the same type
21  but with a void return type.  In practice this probably works fine on most
22  platforms, but it's undefined behaviour and also gives a compiler warning
23  with some compilers.
24
25* Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
26  installed.
27
28Changes in 1.2.39 (2019-06-29):
29
30* Support versions 5.x and 6.x of the PROJ library we use for handling
31  conversions between coordinate systems.  Reported by Bas Couwenberg
32  in #102, by Richard Knapp in #103 and by Martin Sluka in email.
33
34* (Unix and Mac OS versions): When checking if something is a file or if it is
35  a directory, we no longer treat a symlink as being neither, but instead
36  return an answer based on what the symlink points to.
37
38* aven:
39
40  + Improve handling of hidden splay ends.  Previously, hidden splay ends still
41    served as "targets" for snapping the mouse pointer to, and still got
42    crosses when crosses were enabled.  We don't have a handy flag for "this is
43    the outer end of a splay" and computing that on demand isn't so easy to do,
44    so for now we use the "anonymous station" flag so at least these cases now
45    behave properly for splays to anonymous stations (which is likely to be
46    what people with huge numbers of splays from disto-x, etc are using).  This
47    does mean that anonymous stations on continuation passages will incorrectly
48    also be off when splays are hidden, but that seems an OK trade-off for now
49    and a definite improvement over the previous situation.  The snapping of
50    the mouse pointer was reported by Frank Tully in #105.
51
52  + Fix typo in export UI (CVS should be CSV).
53
54* Documentation:
55
56  + Add CSV to documented list of survexport output formats.
57
58  + Fix *declination syntax synopsis - "auto" is a literal string, not a
59    placeholder.
60
61  + Update PROJ project name and website - the name is now "PROJ" (all caps and
62    no ".4" suffix) and the website is now: https://proj.org/
63
64* Install gtksourceview-3.0 language file so .svx files now get syntax
65  highlighting in gedit and other GtkSourceView-based editors.  Patch
66  from Philip Withnall.  Fixes #98.
67
68* (Microsoft Windows version): The Survex installer doesn't uninstall the old
69  version when you upgrade, but just overwrites it with the new version.  In
70  1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
71  an older version would still have cad3d.exe from that old version.  We now
72  remove any old cad3d.exe left over from a previous install in the same
73  location to avoid confusion.
74
75* Add a few more message translations.
76
77* Fix warnings when built with a C++11 compiler.
78
79Changes in 1.2.38 (2019-03-02):
80
81* cavern:
82
83  + Deprecate MILS as angular units.  Survex has long support MILS as an alias
84    for GRADS.  However, this seems to be a bogus definition of a "mil" which
85    is unique to Survex (except that Therion has since copied it) - there are
86    several different definitions of a "mil" but they vary from 6000 to 6400 in
87    a full circle, not 400.  Reported by Andy Edwards.
88
89  + Fix segfault for *include "".  This isn't useful, but shouldn't crash.  It
90    now reports "file not found" instead.
91
92  + Use isnan() to check for not-a-number.  This is cleaner, more robust and
93    more efficient than formatting the number as a string and checking for
94    "NaN" or "nan" in the result.
95
96* Avoid unused variable warning when compiling from source with modern ffmpeg.
97
98* Drop support for wxWidgets < 3.0.  3.0.0 was released over 5 years ago and
99  should be easily available everywhere by now.  I'm no longer easily able to
100  test with wxWidgets 2.8, and this allows a significant amount of cruft to be
101  removed.
102
103* (Linux version): survex.spec: Fedora have removed gcc from the default build
104  environment so need to explicitly list it in the BuildRequires tag.  See
105  https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
106  information.  Patch from James Begley.
107
108Changes in 1.2.37 (2018-11-18):
109
110* aven:
111
112  + Add basic "Colour by Survey" feature.  The colours used aren't currently
113    controllable.
114
115  + Fix export of splays.  Patch from Thomas Holder.
116
117  + Fix KML export to avoid invalid geometry when a tube intersects itself.
118    Patch from Robert Jones.
119
120  + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
121    for now.  This is a workaround until wxWidgets OpenGL support is updated
122    to work under Wayland.  Reported by Philip Balister.
123
124  + Fix warnings about using deprecated functions when building movie export
125    code using FFmpeg 4.0.
126
127* cavern:
128
129  + Compass MAK files: Handle fixed point coordinates in feet - previously the
130    units were ignored and the coordinates assumed to be in metres.
131
132  + Previously the first byte in a MAK file was ignored.  Typically MAK files
133    start with a comment, and since cavern currently ignores lines that start
134    with characters it doesn't understand the meaning of, this bug would often
135    go unnoticed.
136
137* survexport:
138
139  + Fix exporting of passages, walls and cross-sections by running the code
140    aven uses to decide how much to rotate each cross-section.  Previously all
141    cross-sections were aligned West-East.  Reported by Robert Jones.
142
143  + Default to .pos output if the program name is 3dtopos, and install a second
144    copy (or hardlink under Unix) as 3dtopos.  This provides compatibility with
145    current releases of Tunnel.  Reported by Becka Lawson, Wookey and
146    Stephen Crabtree.
147
148* Fix some German translations.  Patch from Thomas Holder.
149
150* (MacOS X version): Fix aven-create-app to not delete converted icons.
151  Typo spotted by Robert Jones.
152
153* Improve documentation for *team.  Document the requirement to quote names
154  unless a person is identified by just one name.  Document that the roles are
155  optional, as that information may not have been recorded, and to align with
156  therion's team command.
157
158Changes in 1.2.36 (2018-07-18):
159
160* aven:
161
162  + Add support for exporting as a CSV (Comma-Separated Values) file.
163
164  + Support exporting KML with altitude mode "clamp to ground".  In this mode,
165    the altitude in the data is ignored and it's rendered on the surface of the
166    terrain.  This is useful if your KML viewer renders the terrain as opaque
167    so underground data isn't visible.  Rendering cave passages on the surface
168    isn't great, but is better than not being able to see them at all.  This
169    option may also be helpful if you want to see where to look on the surface
170    for new entrances.
171
172  + Highlight surveys with a white loop as the mouse is moved over them in
173    the survey tree.  This is akin to how we highlight a station with a
174    white ring, and allows restoring "double-click survey in tree to zoom"
175    which temporarily required a quadruple-click in 1.2.35.
176
177  + Only show checkboxes in the survey tree for surveys not stations.
178
179  + Fix wxWidgets assertion if the user tried to select additional surveys
180    to show via the right-click menu.
181
182  + Fix multiple survey filtering when both a parent and child survey are
183    selected.  In this case it makes most sense to show all child surveys of
184    the parent, but we actually showed a slightly arbitrary subset of the
185    child surveys of the parent.
186
187  + The checkbox area in the survey tree is now included in the area which
188    is considered by mouse-over updates such as highlighting the station or
189    survey.
190
191  + Fix display of double quotes in cavern log window (they were being replaced
192    with control character 0x16 due to a typo in the code).
193
194  + Add shortcuts to buttons in cavern log window.
195
196  + Eliminate use of gluErrorString() function which eliminates some
197    deprecation warnings when building on macOS.
198
199  + Reject multiple --survey command line options for now (only the last has
200    been used for a long time, but now we actually support multiple survey
201    filtering this matters more).
202
203* survexport:
204
205  + Report a useful error when trying to convert a .3d file without coordinate
206    system information to GPS.  Reported by Mark Shinwell.
207
208  + Handle multiple redundant --survey command line options correctly.
209
210* dump3d: Report station flag "WALL", which was added in 1.2.7.
211
212* Minor translation updates.
213
214* Update manual for Microsoft Windows changes.
215
216* tests/: Add test coverage for warnings about suspect readings
217
218* Fix warning when compiling with clang.
219
220Changes in 1.2.35 (2018-07-03):
221
222* aven:
223
224  + Viewing can now be restricted to multiple surveys.  Use the right-button
225    menu on a survey in the survey tree and select "Show" to enable checkboxes
226    for that survey and all its siblings.  Only the selected surveys are shown
227    on screen, printed and exported.
228
229  + Don't open a survey when its name is double clicked.  This was happening
230    due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
231    However, reverting that change still seems to allow double-clicking to work
232    on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
233    survey.
234
235  + Pick initial survey scaling based on whichever of the window width or
236    height gives the smaller scale.  Previously we always used the window
237    width, which can result in parts of the cave being outside the initial
238    view.  Reported by Wookey.
239
240  + Drop ability to specify a PROJ string in the export dialog.  This was added
241    to allow exporting to formats such as GPX before we added support for
242    specifying the projection in .svx files, and that support is now mature.
243
244  + DXF export now uses 2 decimal places (was 6) for the bounding box, for
245    consistency with the precision used for coordinates.
246
247  + Fix handling of surface flag during export.  In formats which discriminate,
248    legs could previously have got assigned the wrong status.
249
250  + Fix bug which probably prevented aven starting when OpenGL double buffering
251    is unavailable.  This is unlikely to affect any common configurations.
252
253  + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
254    filenames.  Issue reported by Matic.
255
256  + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
257    Probably broken since 1.2.17.
258
259* survexport: New command-line export program which uses aven's export code.
260  Replaces 3dtopos, cad3d and findentrances, since it can do all that these
261  tools could do, plus much more.
262
263* Merge more Spanish i18n updates from Evaristo Quiroga.
264
265* Minor updates to various other translations.
266
267* img library:
268
269  + Now supports reading from and writing to an existing FILE*.
270
271  + Improve API documentation.
272
273* (Microsoft Windows version): Fix packaging to include wxWidgets translation
274  files like it was supposed to, which fixes a few missing translations.  This
275  was probably broken by changes in 1.2.8.  Reported by Evaristo Quiroga.
276
277* (Microsoft Windows version): Drop two options from explorer bindings.
278  "Convert to DXF" and "Convert for hand plotting" have both been supported via
279  aven for a while, and that's a more useful way to access them as you can
280  control what gets exported.
281
282Changes in 1.2.34 (2018-03-24):
283
284* aven:
285
286  + (Microsoft Windows version): Fix error on startup in the pre-built version
287    of 1.2.33.
288
289  + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
290
291Changes in 1.2.33 (2018-03-22):
292
293* aven:
294
295  + Reliably disable scale bar in perspective view.  This is supposed to happen
296    (because the scale across the screen varies in perspective view) but
297    actually the scale bar stayed around until an update was forced for another
298    reason.  Spotted thanks to Pedro Silva Pinto.
299
300  + Make "no date"/"not in loop" colour grey.  The white was a bit bright and
301    made it harder to see the legs that had colours.  The grey now used is
302    within the brightness range of the other colours.  Fixes #94, reported by
303    Erin Lynch.
304
305  + Fix KML export - exporting both survey legs and station names resulted in a
306    malformed KML file.  This bug was introduced in 1.2.30 when support for
307    exporting passages and walls was added.  Reported by Erin Lynch in #90.
308
309  + Consistently use 2 decimal places for altitude in KML output.  Some places
310    used 8 decimal places which is appropriate for lat and long, but clearly
311    overkill for an altitude in metres and increases the file size
312    unnecessarily.
313
314  + Right-align bearing widget in print/export dialog.  The change to allow the
315    value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
316    left-aligned (due to incorrect wxWidgets documentation of the default style
317    for this control).
318
319  + (Unix version): Work around wxWidgets bug so that custom cursors work
320    under GTK3.
321
322  + (Unix version): Update GTK version reporting - report GTK3, and don't
323    bother to report subversions of GTK2 (it seems to be fairly arbitrary
324    which subversions wxWidgets defines constants for).
325
326  + Update code to work without warnings when using wxWidgets 3.1.0 (the
327    current development version).
328
329  + Make movie export code compatible with upcoming FFmpeg 3.5 release.
330    It should still work with the older versions that worked before this
331    change.  Reported by James Cowgill in https://bugs.debian.org/888334
332
333* cavern:
334
335  + Warn about 2 digit years.  We can't change the assumption that these are
336    19xx without risking breaking existing datasets, but the further we get
337    into this century, the more likely such an assumption is to catch someone
338    out.  The warning can easily be quashed by explicitly adding the assumed
339    "19".
340
341* The Spanish translation is now up to date once more, thanks to updates from
342  Evaristo Quiroga.
343
344* Merge French translation updates from Jean-Marc.
345
346* Fix transposed German Northing and Easting labels.  Fixes #95, reported by
347  milosch.
348
349* Fill in missing translations of "Easting", "Northing", "E" and "N" for
350  Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
351  translated messages.
352
353* Align .pos file headings better with columns of coordinates below for
354  Indonesian and Polish.
355
356* Fix handling of the message string "error" before messages loaded.  If
357  there's an error loading messages, we need this message to report it.
358  Reported by Martin Sluka.
359
360* Fix a few compiler warnings.
361
362* img library: Fix extracting leaf survey name for survey title.  When there
363  are three or more levels of survey, we were taking everything after the first
364  dot rather than everything after the last dot.
365
366* Fix problems with testsuite on macOS:
367
368  + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
369    - this test isn't meaningful unless the filing system is case-sensitive,
370    but happens to fail if it isn't.
371
372  + cavern.tst: Workaround limitations of Apple's sed.
373
374  + aven.tst: Fix not to hang on macOS.
375
376  + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
377
378* Clean up handling of support files in relocatable installs - this is now
379  detected at run time on macOS.
380
381* Split out macOS Aven.app creation into a make rule so it can be easily used
382  by the homebrew formula.
383
384* buildmacosx.sh:
385
386  + Fix when WX_CONFIG not specified - this was giving a confusing error like:
387    ./buildmacosx.sh: line 163: --cc: command not found
388
389  + Use wxWidgets 3.0.4.
390
391* Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
392  and we currently require 2.8 or newer.
393
394Changes in 1.2.32 (2017-07-08):
395
396* aven:
397
398  + Make splays on printouts a darker shade of grey.  Reported by Erin Lynch
399    and Anthony Day.
400
401  + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
402    POS), the value in the Z dimension was negated.  Bug introduced by fixes
403    for export of rotated plans and tilted elevations in 1.2.27.  Reported by
404    Erin Lynch in #89.
405
406  + Ignore viewing angles for export formats which work in 3D.  When the
407    rotation and tilt controls are hidden in the export dialog we were still
408    using their values to transform the data, so if you set them with for one
409    export format which support them, then switched to an export format which
410    doesn't, you'd get bogus coordinates in the exported file.  Bug probably
411    introduced in 1.2.27 by fixes for exports of rotated plans and tilted
412    elevations.
413
414  + Fix exporting to skencil and Survex .pos formats.  When aven's export to
415    .pos was added in 1.2.19, the ordering didn't match up and since then .pos
416    export has produced skencil files and vice versa.
417
418  + Don't leave terrain on if loading terrain data fails.  Previously if you
419    clicked the terrain icon (or via the menu) with no terrain loaded, but no
420    terrain got loaded (e.g. because the survey data lacks an explicit
421    coordinate system, or because the file failed to load, or because you
422    cancelled the dialog) then the terrain icon/menu item was still changed to
423    "on".
424
425  + Disable texturing while drawing terrain.  Previously the terrain got a bit
426    darker when "Textured Walls" were enabled.
427
428  + Force a refresh when "Textured Walls" are enabled or disabled.  Previously
429    the display wouldn't update right away.
430
431* Manual:
432
433  + Document how to specify fixed point altitude in feet.
434
435  + Explain why *fix warns about unused fixed points
436
437* Building from source now requires a compiler with decent support for C++11.
438  If you're using GCC, then GCC 4.7 should suffice.  This should not be an
439  onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
440  enough GCC.  If special options are needed, these should get probed for and
441  automatically.  Fixes building 1.2.31 with GCC < 6, reported by Wookey.
442
443Changes in 1.2.31 (2017-07-01):
444
445* aven:
446
447  + Use superscript 'g' symbol instead of word 'grads' in status bar.  This
448    conserves the limited space available, and we already do this in the
449    compass and clino indicators so it's more consistent too.
450
451  + Show one decimal place on measure line bearing.  Pointed out by Benedikt
452    Hallinger on the therion list, though I'm sure this has been asked for
453    before by others.
454
455  + Show gradient of the measuring line when both ends are stations.
456
457  + Allow selection of text in cavern log window.  Selection was disabled in
458    1.2.28 because it seemed you couldn't actually copy selected text to the
459    clipboard, but retesting this now actually works fine for me, both with
460    current git master with the change reverted, and with code just before the
461    original change.
462
463  + More robust parsing of cavern output (cleanly handle context highlighting
464    which extends beyond the end of the line).
465
466  + Allow showing duplicate legs as dashed lines or hiding them entirely,
467    with dashed now being the default.  Implemented by Patrick Warren.
468
469  + Also allow "Dashed" for splays and "Faded" for duplicate legs.
470
471  + Splay legs in surface data are also shown faded.
472
473  + Check environment variables VISUAL and EDITOR when looking for editor to
474    use when a warning or error is clicked on in the cavern log window.  The
475    specified editor may have a GUI or need to run in a terminal, so we have to
476    special-case each editor supported, and that means we can pass extra
477    options needed to position the cursor on the appropriate line/column.
478    Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
479    emacs, nano, jed, kate.  Suggested by Wookey.
480
481  + Fix handling of non-square terrain data files - the X and Y dimensions were
482    swapped.  Reported by detrito.
483
484  + Improve parsing of DEM data with .hdr file.  Use documented defaults for
485    more values, and where we only support a subset of values (or a particular
486    value) check for unsupported values in more cases.
487
488  + When colouring by depth, fix colouring and texturing of polygons which
489    cross depth bands.  The previous problems were most obvious with high
490    chambers and long legs down deep pitches, especially in for surveys without
491    much vertical range.
492
493  + Support for drawing blobs using point sprites was added in 1.2.28,
494    but caching that this worked wasn't hooked up properly so the test to
495    see if this worked would happen at the start of each run.  This is now
496    cached as intended which should reduce start up time a little when blobs
497    are drawn in this way.
498
499  + Fix drawing of crosses with lines.  This is a fall-back case which is
500    rarely used as most OpenGL setups will handle a better method, but it was
501    resulting in crosses with a four-pixel square in the centre - now the
502    centre should be a single pixel.
503
504* cavern:
505
506  + Allow *data with no arguments to reset the current style - useful for
507    entering passage data where there are side passages.
508
509  + Fix hang processing file without newline at end.  This bug was introduced
510    by changes in 1.2.28.  Reported by Mark Brown.
511
512  + (Mac OS X and Microsoft Windows versions): Build with newer version of
513    PROJ library which fixes buggy handling of *fix with lat-long coordinates.
514    Also add a testcase to the testsuite to alert users building for themselves
515    with an affected PROJ version on any platform.  Reported by Ross Davidson.
516
517  + Fix cavern to handle Compass .DAT with no survey team.  Previously this
518    resulted in the bogus error: Expecting numeric field, found "FROM"
519    Reported by Erin Lynch.
520
521  + Handle UTF-8 "BOM" at start of .svx files.  Unicode doesn't recommend its
522    use, but Microsoft stuff seems to like to create files with it in, and the
523    error cavern currently reports for such files is very confusing, so it
524    seems best to just handle it.  Reported by Rob Eavis.
525
526  + Change a couple of messages to use double quotes for consistency with all
527    other messages.
528
529* extend:
530
531  + Now runs a bit faster.
532
533  + Splays are now carried over the extended survey.  The current handling
534    is simplistic, but should do a good enough job to be more useful than
535    discarding splays.  The splays at each station are all rotated together
536    based on the bearing between the stations either side of the current one
537    along the first path extended through that station.  This nicely handles
538    dead ends and the situation at the top or bottom of a pitch, and should
539    tend to pick an angle close to the passage orientation along a traverse.
540    It's weakest at junctions.  Feedback (especially examples which could
541    be handled better) most welcome.
542
543* French translation is now up to date again, thanks to Jean-Marc.
544
545* Remove erroneous menu shortcut markers from Polish translations.
546
547* Fill in some missing translations in several languages by using message
548  translations from therion.
549
550* Add note to *fix documentation to clarify the coordinate order with *cs
551  long-lat.  Issue raised by Ross Davidson.
552
553* Fix errors in documentation of *units: "DEG" should be "DEGS", and
554  "MINUTES" has been supported for ages but wasn't documented.  Reported by
555  Footleg.
556
557* Fix a few typos in the documentation.
558
559* Fix compilation warning with recent GCC.
560
561Changes in 1.2.30 (2016-10-03):
562
563* aven:
564
565  + (Microsoft Windows version): Fix crash when trying to print or export
566    (probably introduced in 1.2.28).  Reported by Brian Clipstone.
567
568  + Report error if terrain file contains no terrain data in area of survey.
569    Suggested by detrito.
570
571  + Errors when writing an export file were reported with the wrong filename
572    - the .3d file, not the filename we were trying to write to.
573
574  + Export to KML now supports exporting passages, walls and cross-sections.
575    Addresses the remainder of ticket #4.
576
577* Add man page for dump3d.
578
579Changes in 1.2.29 (2016-09-27):
580
581* aven:
582
583  + Fix SVG output with non-ASCII characters (the charset in the SVG file
584    is now set to UTF-8 not ISO-8859-1).
585
586  + (Microsoft Windows version): Fix error dialog on startup in pre-built
587    version.  Reported by Brian Clipstone.
588
589* Manual: Add link to TerrainData wiki page.  Omission highlighted by Erin
590  Lynch and "detrito".
591
592* Fix to build without FFmpeg/libav and with older versions, broken by changes
593  in 1.2.28.  Reported by James Begley.
594
595Changes in 1.2.28 (2016-09-24):
596
597* cavern:
598
599  + Show the contents of the line after error and warning messages while
600    processing survey data, and indicate the region of the line in many cases
601    in the same style that compilers such as GCC and clang use (using the
602    column number we already have, plus new width information).  Based on a
603    patch from Mateusz Golicz.
604
605  + Add column and width information for many more error and warning messages.
606
607  + Fix column for "Separator in survey name" warning.
608
609  + Improve warnings when using a backclino with range 0-180 degrees (reusing
610    the same machinery we already have for a forward clino with range 0-180
611    degrees).
612
613* aven:
614
615  + Include LRUD in printout/export of extended elevations, broken by
616    improvements to export of tilted elevations in 1.2.27.  Reported by Anthony
617    Day.
618
619  + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
620    usefully.  Reported by Anthony Day.
621
622  + Remember scale from previous print or export operation in the same run of
623    aven.  Suggested by Stuart Bennett.
624
625  + Convert range indication below shown line to a highlight on that region
626    of the line in cavern log window.
627
628  + Fix colouring of error/warning without column in cavern log window.
629
630  + Fix click on error/warning without column in cavern log window.
631
632  + Fix highlight of translations of "error" or "warning" containing non-ASCII
633    characters.  This fix for this only works with a Unicode build of
634    wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
635    shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
636    Reported by Mateusz Golicz.
637
638  + Disable selection of text in cavern log window - you can't currently copy
639    it to the clipboard, so until that's implemented it seems better to disable
640    the ability to select it.  Reported by Wookey.
641
642  + Avoid special "1000" scale entry when exporting.
643
644  + Show 1 page when "One Page" selected.
645
646  + Reload processed data when restricting view.  Fixes failure when
647    restricting view on data just processed via aven.  Spotted by Andrew
648    Atkinson and myself.
649
650  + Don't hide blobs and crosses behind terrain.  Reported by Jenny Black.
651
652  + Fix rendering of crosses using point sprites.  The texture being used was
653    misaligned relative to the image used for the visual fidelity check, so the
654    check always failed and point sprites would never be used.  Where point
655    sprites are supported, they're probably the fastest option - on my netbook
656    this change improves FPS by ~6 fold when displaying crosses for a large
657    survey.
658
659  + Support drawing blobs using point sprites.  About 5 times faster than using
660    lines on my netbook.
661
662  + Recheck how best to draw crosses and blobs on the first run after Survex
663    is upgraded (or downgraded) as the rendering code may have changed (we
664    already recheck when the OpenGL hardware or driver changes).
665
666  + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
667    MPEG4 produces smaller output of higher quality, and should be widely
668    supported these days.  And I can't get the MPEG1 output to work without
669    buffer underflows, resulting in a file which doesn't play without
670    glitches.
671
672  + Add OGG video to the list of formats - it's more compact than the others
673    we currently list, though slower to write.
674
675  + Fix export to movie formats for which libav/FFmpeg needs to seek the file
676    being written.  This was broken by changes in 1.2.27.
677
678  + Overhaul movie export for the current FFmpeg API, fixing deprecation
679    warnings when building against a recent version.
680
681  + (Microsoft Windows version): Fix corrupted exported movie files.  1.2.27
682    changed the movie export code to allow writing to files with non-ASCII
683    characters in the names, but the new code failed to open the file in binary
684    mode, leading to corrupt output.  Fixes #81, reported by Erin Lynch.
685
686  * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
687    movie export.
688
689  * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
690    export.
691
692* Fix to build without FFmpeg/libav, broken by changes in 1.2.27.  Reported by
693  James Begley.
694
695* The Polish translation is now very close to being complete, thanks to a
696  substantial update from Mateusz Golicz.
697
698* Merge catalan translation updates from Adolfo Jayme.
699
700* (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
701  messages get used automatically.
702
703* cavern.tst: Remove random : from after ] - dash ignores the extra character,
704  but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
705
706* cavern.tst: Add expected output for more testcases.
707
708* Remove unwanted execute bit from some testcase data.
709
710* Use https for more URLs which support it.
711
712Changes in 1.2.27 (2016-06-06):
713
714* aven:
715
716  + Right click on a survey in the survey tree now gives a pop-up menu
717    with "Hide others", which restricts the view to just that survey
718    and any subsurveys.  Right click on the root of the survey tree
719    gives a menu with "Show all" to undo any restriction in effect.
720    (Currently these are implemented by reloading the file and using
721    the same machinery as the --survey= command line option, but that will
722    probably change in the future).
723
724  + If there's a sub-survey restriction (from the --survey= command line
725    option or the new UI described above) it is now shown in brackets after
726    the survey tree root.
727
728  + When reloading a survey, preserve the current view position (previously
729    the view was recentred).
730
731  + When reloading a survey, actually preserve the current scale factor
732    (this was meant to happen, but the adjustment was applied in the
733    wrong direction).
734
735  + New "File->Extended Elevation..." menu item provides a way to generate
736    extended elevations for simple cases without having to use the command
737    line.  Suggested by Fleur Loveridge.
738
739  + Don't process key presses if accompanied by an unexpected modifier key.
740    In particular, this means that aven no longer interferes with Alt+<function
741    key> (which is typically handled by the desktop) and Alt+<letter> (which is
742    typically a menu short cut).  Reported by Владимир Георгиев.
743
744  + Reduce file loading time by ~5%.  The station name compare function was
745    something of a hot spot, and optimising it yielded a nice improvement.
746
747  + Allow splay legs to be disabled in when printing and exporting.  Mostly
748    addresses #60.
749
750  + SVG export now shows splay legs thinner and in grey.  See #60.
751
752  + Fix export of rotated plans and tilted elevations - previously plans were
753    always aligned with North up, and elevations which weren't exactly side on
754    were exported as plans.  Reported by Stuart Bennett.
755
756  + Fix offset bounding box for exported elevations.
757
758  + In print/export dialog the bearing value now wraps if you scroll up past
759    360 or down past 0.
760
761  + Fix greying out of LRUD-based controls in the print/export dialog when the
762    view is tilted (i.e. not plan or elevation).  This stopped working in
763    1.2.18 when the pan and tilt spin controls were changed from integer- to
764    real-valued ones.
765
766  + Printouts now show LRUD as pale grey arrows from the station they are
767    measured from.  Based on patch from Michael Sargent.  Closes #65.
768
769  + Take LRUD into account for printout size.  Fixes #72, reported by Erin
770    Lynch.
771
772  + Update movie export code to work with latest version of FFmpeg.
773
774  + Make "Show Log" a toggle, so you can click on the button to take a look at
775    the log, and a second click returns you to the survey view.
776
777  + (Microsoft Windows version): Open the font file in binary mode - it looks
778    like we were lucky and the font file (or at least its current version)
779    would have loaded OK in text mode despite being binary data.
780
781  + (Microsoft Windows version): Exporting to files with non-ASCII filenames
782    should now work.
783
784* cavern:
785
786  + Allow tape or backtape to be omitted.  Reported by Erin Lynch.
787
788  + Grid convergence is now corrected for when using automatically
789    calculated declinations (*declination auto <X> <Y> <Z>).  Requested
790    by Mateusz Golicz on the mailing list.
791
792  + Clear any cached calculated declination upon another *declination auto
793    with different coordinates.  Previously if the date stayed the same,
794    a previously cached declination for the old coordinates was used.
795
796  + Fix check for end of version number array in *required.   We would check up
797    to 12 version components, the last 9 being bogus.  In practice, *require is
798    only likely to be used with up to three components, so this wouldn't be an
799    issue.
800
801  + *begin with an invalid prefix could cause a crash in some cases.  Fixed
802    by patch from Colin Watson.
803
804  + Report column locations for errors to do with readings.
805
806* Merge translation updates from Jean-Marc.
807
808* img library: Better document which members can be set when writing.
809  Highlighted by email query about use of img API from Владимир Георгиев.
810
811* Document how *declination interacts with *calibrate declination if both are
812  used in the same dataset.
813
814* doc/3dformat.htm: Update details of how changes to the current label buffer
815  are encoded to reflect changes in v8.  Reported by Angus Sawyer.
816
817* Use docbook2man instead of docbook-to-man to generated Unix man pages
818  from SGML source.  The latter seems to be no longer actively maintained, and
819  docbook2man now does a similarly good job.
820
821* Use https for survex.com links, and for other sites which support it.
822
823Changes in 1.2.26 (2016-01-07):
824
825* aven:
826
827  + (Microsoft Windows version): Fix to be able to process .svx files with
828    cavern again.
829
830* (Microsoft Windows version): Simplify upgrading process with innosetup
831  installer - if Survex is already installed, we now just install to the same
832  location and use the same start menu folder.
833
834* (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
835  Fixes #79, reported by James Begley.
836
837* (Linux version): survex.spec: Fix to work with RPM 4.13.  Fixes #79, reported
838  by James Begley.
839
840Changes in 1.2.25 (2016-01-05):
841
842* aven:
843
844  + Drop broken code which attempts to fix 2D pitches.  Fixes #73, reported by
845    Erin Lynch.  #76 tracks the issue the removed code was trying (but failing)
846    to address.
847
848  + When animating, don't try to update station info based on mouse movement
849    over the survey tree.
850
851  + Further improve code to handle cavern subprocess in aven.
852
853  + Fix jump to error for filenames containing colons when the error location
854    doesn't have a column number.  Bug noted by Jenny Black.
855
856  + If we encounter bad UTF-8 in cavern output, replace it with a red and white
857    ? in a diamond (previously we gave up showing output at the first bad
858    sequence).  This can happen if you process a .svx file which isn't UTF-8
859    encoded.
860
861  + (Unix version): Don't try to set the terminal window title when opening an
862    editor from the cavern log window - gnome-terminal no longer supports this,
863    and there doesn't seem to be a portable option for specifying the title for
864    terminals which do still support this.
865
866  + (Microsoft Windows version): Also quote for cmd.exe so that paths with
867    spaces in work reliably.  Reported by Marco Cotto.
868
869* cavern:
870
871  + Improve error for mismatched fore/back-sight plumbs, reported by Andy
872    Edwards (see #78).
873
874  + Fix to use correct sd for backcompass.  We were using zero instead, the
875    most obvious effect of which was that the threshold for warning about
876    differing COMPASS and BACKCOMPASS was about 71% of what it should have
877    been, so we were warning in more cases than we should have been.
878
879  + Implement support for specifying a length on backsights - if you're using
880    something like a disto-x, you'll get a distance reading for the backsight
881    too.  Fixes #71, reported by Erin Lynch.
882
883  + Make line counting more robust to mixed line ends.  Noticed in example file
884    from Pete Smart (see #69).
885
886* extend: New --show-breaks option which adds a leg flagged as surface survey
887  between each points at which a loop has been broken.  Suggested by Jenny
888  Black.
889
890* (Unix version): Update filetype metadata to work with modern desktops.
891
892* Fix incorrect reporting of errors reading and writing processed survey data.
893  Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
894  IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
895  external programs using the img library, only Survex).  Reported by Jenny
896  Black.
897
898* Add missing options to extend man page and --help output.  Noted by Jenny
899  Black.
900
901* Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
902
903* Fix broken SGML markup in manual.
904
905* Fix typo in manual reported by Jenny Black.
906
907* Update vim syntax file for newer commands, etc.
908
909* Minor translation updates.  Thanks to Piotr Strębski and Jean-Marc.
910
911* Fix to compile with FFmpeg 2.9.  Reported by Andreas Cadhalpun in
912  https://bugs.debian.org/803863
913
914* Stop maintaining ChangeLog files.  They make merging patches harder, and stop
915  'git cherry-pick' from working as it should.  The git repo history should be
916  sufficient for complying with GPLv2 2(a).
917
918* (Microsoft Windows version): The installer requires admin privileges on Vista
919  and later and OS versions older than Vista are past end of life, so drop code
920  which tries to set up the registry differently depending if we have admin
921  privileges or not.
922
923Changes in 1.2.24 (2015-09-23):
924
925* aven:
926
927  + (Microsoft Windows version): Fix the cavern log window.  Reported by Brian
928    Clipstone.
929
930  + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
931    Reported by Jenny Black.
932
933  + If wx was built with thread support, aven now runs cavern from a separate
934    thread, which works much better under wxMSW (where we can't use select),
935    and also seems a bit smoother on Linux.
936
937  + Fix handling of encoding of filenames when the operating system has no
938    locale installed corresponding to the language selected for Survex's
939    messages.
940
941  + Undo accidentally committed debugging code which was sending message to
942    the terminal in 1.2.23.
943
944* (Linux version): configure now looks first for wx-config-3.0, which Fedora's
945  wx3 packages have.  Reported by James Begley.
946
947* Indonesian translation fully up to date again.
948
949* Manual: Document anonymous stations, based on the text from NEWS.  Reported
950  by Wookey.
951
952Changes in 1.2.23 (2015-09-06):
953
954* aven:
955
956  + Updating the cavern log window is now much smoother, especially on slower
957    machines.
958
959  + Show "busy" mouse cursor while processing survey data.
960
961  + Fix an assertion if you try to start processing a survex file while one is
962    already being processed.
963
964  + Processing a .svx file with an error now still adds it to the file history.
965    Reported by Martin Green.
966
967  + Fix the orientation of the starting end of tubes.
968
969* cavern:
970
971  + New *ref command to allow specifying an external reference (e.g. where to
972    find the original survey notes).
973
974  + Drop support for showing percentage progress in cavern.  It's confusing in
975    a multiple-file dataset as it shows progress in the current file so jumps
976    around.  It also slows down processing, and on a slow machine you'd don't
977    want that, while on a fast machine processing isn't slow enough for the
978    progress display to be useful.
979
980* French translation is now completely up to date, thanks to Michel Bovey.
981
982* Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
983  OS X so that things like "*cs EPSG:29903" work.  Reported by Graham Mullan.
984
985* (Microsoft Windows version): Process survey data with aven rather than
986  running cavern.
987
988* (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
989  releases have been built with 5.5.3) to see if that solves Ray Duffy's
990  reported issue with not having file associations for .svx files created.
991
992Changes in 1.2.22 (2015-08-17):
993
994* aven:
995
996  + Ensure that the window has a depth buffer.  Whether it does by default
997    seems to vary depending on OS and maybe graphics card.  Fixes #55 (terrain
998    is no longer visible through itself), and also the rendering of passage
999    tubes.  Thanks to Martin Green for pointing me in the right direction for
1000    finding this fix.
1001
1002* cavern:
1003
1004  + Fix *declination with an angle to actually work.
1005
1006  + Fix assertion if we try to identify a hanging survey by an anonymous
1007    station.
1008
1009  + Improve errors for invalid survey names in *begin, *end, *equate and
1010    *export.
1011
1012Changes in 1.2.21 (2015-07-28):
1013
1014* aven:
1015
1016  + Fix exporting to KML and other text-based formats to always use "." for the
1017    decimal separator - previously "," would be used when the user's locale
1018    specified this for the decimal separator.  Reported by Jan Schorn.
1019
1020  + Implement exporting of survey legs in KML format.
1021
1022  + Put "paddle" placemarker icons on stations in exported KML files, using the
1023    same colour coding for entrances, fixed points and exported points as aven
1024    does.
1025
1026  + Remove the "Coordinate projection" field from the print dialog, as it isn't
1027    relevant there.  Reported by Wookey.
1028
1029  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1030    been too small).  Reported by Wookey.
1031
1032  + Don't rescale if the same file is reloaded, but adjust the volume diameter
1033    as appropriate.
1034
1035  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1036    values on Windows.
1037
1038* cavern:
1039
1040  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1041    radians, but we were passing degrees, which would generally cause the
1042    conversion to the output coordinate system to fail.  Reported by Wookey.
1043
1044  + Fix *fix with standard deviations when *cs is in use, give an error for use
1045    of *fix with standard deviations before *cs.
1046
1047  + Add new *declination command with support for setting the declination
1048    automatically from the IGRF model based on the survey date.  Thanks to the
1049    Therion developers for the IGRF support code, which we're reusing.
1050    Fixes #54, reported by Wookey.
1051
1052  + Allow the units for the zero error to be specified, making it easier to
1053    specify calibration with a scale if you measure the zero error externally
1054    (rather than using the instrument itself).  Fixes #61, reported by Andrew
1055    Atkinson.
1056
1057  + Report the error from PROJ when coordinate conversion fails as part of the
1058    actual error rather than on a separate line.
1059
1060  + Fix use after free after *solve.  This only occurs if a leg between the two
1061    exact same stations appears right before and right after the *solve, which
1062    is unlikely in real data, but the testsuite has an instance of this.  This
1063    was introduced by the repeat leg averaging added in 1.2.17.
1064
1065  + Fix small memory leak when solving network.  This doesn't really matter
1066    when solving at the end of processing as cavern will exit after that, but
1067    if *solve is used we continue processing after solving.
1068
1069* Remove compatibility handling for specifying a country variant of a language
1070  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1071  changed to the standard "en_US" way back in 2001.  This code was mangling
1072  character sets with a "-" in, and is no longer useful.
1073
1074* Ignore any "@<something>" modifier in the language code.
1075
1076* Improve documentation of magnetic declination handling, and cover the new
1077  "*DECLINATION" command.
1078
1079* Document aven's command line options in the manual and its man page.
1080  Reported by Jenny Black.
1081
1082* Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1083  documentation.
1084
1085* Remove references to SpeleoGen from the documentation - it hasn't been
1086  updated for many years, and can't read recent versions of the .3d format.
1087
1088* Strip documentation references to obsolete versions of MS Windows.
1089
1090* doc/HACKING.htm: Update list of debian packages to install to build from git.
1091
1092Changes in 1.2.20 (2015-06-26):
1093
1094* aven:
1095
1096  + When printing, use the top margin rather than the right margin to calculate
1097    the height of the printable area.  In practice, the two values seem to be
1098    the same or very similar by default.
1099
1100  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
1101    Maynard.
1102
1103  + Optimise the size of the about dialog images.
1104
1105  + Add support for reading terrain data which isn't in a .zip file.
1106
1107  + Force a refresh after loading terrain data so that it gets displayed right
1108    away.
1109
1110  + Make checks for terrain data extensions in zip files case insensitive.
1111
1112  + If reading terrain data fails, always report an error and never try to
1113    display it.
1114
1115* cavern: Allow clino readings in diving style data, suggested by Andrew
1116  Atkinson.  Currently these readings are ignored, but a future version will
1117  check that they're consistent with the angle given by the depth gauge and
1118  tape, and perform suitable averaging.
1119
1120* Remove lingering traces of svxedit.
1121
1122* configure: Fix to allow compiling without libav/ffmpeg, as was possible
1123  before 1.2.19.
1124
1125* (Unix version): Install the filetype and aven application icons under
1126  /usr/share/icons/hicolor, which is where they're expected to be these days.
1127
1128* (Unix version): Add %f to Exec in survex-aven.desktop.
1129
1130* (Mac OS X version): Remove useless extra copy of about box images from OS X
1131  disk image.
1132
1133* (Mac OS X version): Only ship one copy of each of the translations.
1134
1135* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1136  libav features we don't use.
1137
1138* (Microsoft Windows version): Reduce the size of the aven binary by disabling
1139  a load of libav features we don't use.
1140
1141* (Microsoft Windows version): Update message files to fix a missing Chinese
1142  message in the installer.
1143
1144Changes in 1.2.19 (2015-06-18):
1145
1146* aven:
1147
1148  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1149    the exported file in 1.2.18.
1150
1151  + Add exporting to Survex .pos format.
1152
1153  + If the measuring line isn't currently active, pressing "Escape" will now
1154    exit full screen mode.
1155
1156  + (Mac OS X version): Change the shortcut for full screen mode to be the
1157    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1158    using since 1.2.7).
1159
1160  + (Mac OS X version): When we centre the view on the station this can
1161    generate a mouse move event, so clear the variable which says we are
1162    dragging before we process a left click on a station.  This avoids random
1163    rotations of the survey when clicking on a station, reported in #47 by Hugh
1164    St. Lawrence.
1165
1166  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1167    icons from being rescaled and looking fuzzy.
1168
1169  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1170    toolbar icons from being rescaled, but which requires an unreleased version
1171    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1172
1173  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1174    the top of the screen, since we can't seem to display the menu bar in this
1175    case like we do on other platforms.
1176
1177  + (Mac OS X version): Enable aven's movie export feature.
1178
1179  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1180    support multi-monitor setups.
1181
1182  + (Mac OS X version): Silence warning visible when aven is run from a
1183    terminal about a missing CFBundleTypeRole.
1184
1185  + When reading terrain data from a .zip file, report an error if the .zip
1186    file is bad, or if it doesn't contain any terrain data we recognise.
1187
1188  + Tweak error message in terrain reading code to distinguish two failure
1189    cases.
1190
1191  + Add viewing angles and scale to footer, and shorten some of the other items
1192    to make room for this extra information.  (Fixes ticket #52, reported by
1193    Erin Lynch)
1194
1195  + If the footer is wider than the printout width, scale down the font used
1196    so that it exactly fits; if the footer is narrower, than space out the
1197    items in in so it uses the full width.
1198
1199  + If the saved size for aven's window exceeds the current display size
1200    (mostly likely because we're now plugged into a smaller monitor), then
1201    reduce the size of the window to fit the display.  If the saved size is <
1202    (480x320), increase it to at least that, as aven isn't usable in a smaller
1203    window.
1204
1205  + Remove crude bodge which tries to pick a nicer initial window size when
1206    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1207    with the same size window it had when it was closed, so the initial size is
1208    only relevant on the first ever run.
1209
1210* Assorted translation updates.  Notably Indonesian is at 100% again.
1211
1212* Stop trying to catch and report signals.  The only real reason to do it is so
1213  we can say "Bug in program detected! Please report this to the authors"
1214  before we exit, but when the program crashes that's pretty obvious.  In aven
1215  we try to pop up a message box for this message, which may fail due to
1216  whatever caused the signal, while with the command line tools there's no
1217  great benefit over just letting the shell report the signal.
1218
1219* Use pkg-config to probe for libav and proj, which sorts out the correct flags
1220  for building on OS X against a static install of libav.
1221
1222Changes in 1.2.18 (2015-06-03):
1223
1224* aven:
1225
1226  + Add support for reading terrain data (from a zip file containing either an
1227    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1228    rendering it as a transparent surface.
1229
1230  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1231    sanely want to perform from the menu.
1232
1233  + Create a "Colour by" submenu of the "View" menu to house the various
1234    colouring options.
1235
1236  + Add "Colour by Gradient" and "Colour by Length".
1237
1238  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1239    which seems more logical, and also allows the dialog to be closed by
1240    pressing "Escape".
1241
1242  + Destroy any existing clipping region before we write the page footer.
1243    Hopefully solves ticket #52, reported by Erin Lynch.
1244
1245  + Don't round bearing and tilt angles to integers when printing and
1246    exporting.
1247
1248  + Add passage export for EPS format.  (Partly addresses ticket #4)
1249
1250  + Add JSON export.  This should be regarded as experimental, and the format
1251    is quite likely to change.
1252
1253  + Pressing F6 now toggles the display of rendering stats, currently FPS
1254    (Frames Per Second) and the number of triangles in the terrain mesh.
1255
1256  + Add a menu item and toolbar button to show the cavern log window if the
1257    currently shown survey data was processed by aven.  Reported by Hugh St
1258    Lawrence in #47, and by Dave Clucas and others previously on the list.
1259
1260  + Add "Save Log" button to Aven's cavern log window.
1261
1262  + In cavern log window, highlight "error" markers in red and "warning"
1263    markers in orange.
1264
1265  + Rework code to read cavern's output.  In particular, we no longer mix
1266    buffered and non-buffered system calls.
1267
1268  + Aven's support for reading colours and font sizes for printouts from
1269    print.ini has never worked - the contents of the ini files are ignored due
1270    to a bug which has been there since the code was added in 2005 - but nobody
1271    has ever complained.  So just strip out that code entirely - we should
1272    support setting the colours and font sizes, but a GUI interface for setting
1273    them would be better.
1274
1275  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
1276    Gee.
1277
1278  + Take the width of the messages used above the compass and clino into
1279    account when calculating how much space to allow for them - now the labels
1280    won't overlap or be cut off in translations where they are long.
1281
1282  + (Mac OS X version): Attempt to address the size of the toolbar icons.
1283
1284* cavern:
1285
1286  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
1287    susscorfa).
1288
1289  + Use the currently set units when outputting measurements in warnings,
1290    errors, and the stats at the end of the run.  Requested by Bill Gee.
1291
1292  + Include column number when a *include file isn't found.
1293
1294  + Show 'error' in front of error messages, like we show 'warning' in front of
1295    warnings.  Fixes #48, reported by Wookey.
1296
1297  + Increase the threshold for warning that fore and back measurements differ
1298    from 2 SDs to 3 SDs.
1299
1300* findentrances: If the 3d file specifies the coordinate system, use it.
1301
1302* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1303  would be nice to have, svxedit doesn't really offer that, and it looks ugly
1304  in a modern desktop.
1305
1306* If we run out of memory while reading a processed survey data file, include
1307  the filename in the error message.
1308
1309* Many translation updates - notably Indonesian and Russian are now the two
1310  most complete translations.
1311
1312* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
1313
1314* Transliterate gradient and infinity symbols if the current character set
1315  lacks them.
1316
1317* Add SVG version of .plt icon.
1318
1319* Manual:
1320
1321  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
1322    highlighting that the previous list was incomplete.
1323
1324  + Document averaging of a group of repeated readings.
1325
1326  + Add a link to the sample data from the manual.
1327
1328  + Remove references to contact addresses which are no longer there.  Remove
1329    offer to post people floppies, and references to a CD image which isn't
1330    available for download.
1331
1332* Remove non-breaking spaces from the diffpos and extend manual pages, as they
1333  actually make the output formatting worse (presumably these used to work
1334  around a since-fixed bug in one of the docbook processing tools).
1335
1336* doc/TODO.htm: Update.
1337
1338* Fix to compile without warnings with 'g++ --std=gnu++11'.
1339
1340Changes in 1.2.17 (2015-02-24):
1341
1342* MacOS X version:
1343
1344  + Update INSTALL file with current status.
1345
1346  + Aven.app now has a custom icon.
1347
1348  + Add icons for all the filetypes supported.
1349
1350  + Add Finder actions for .svx, .3d, .plt and .pos files.
1351
1352  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1353    currently do this for us.
1354
1355  + aven: Fix short-cut for toggling Full Screen mode.
1356
1357  + aven: Make "About" menu item appear.
1358
1359  + aven: Fix "Close" button in about dialog.
1360
1361  + aven: Make custom cursors black with a white outline to match the standard
1362    OS X cursor.
1363
1364  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
1365    still doesn't really work like a standard app though - e.g. you can't load
1366    files from Finder (instead run svxedit.app and use File->Open), the font
1367    size of most menu items is wrong, the icon for the app is the wish icon
1368    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1369    probably more.  I'd probably recommend using another editor (OS X comes
1370    with TextEdit.app for example).
1371
1372  + The documentation is now in a "Docs" directory alongside the apps, rather
1373    than in the rather less obvious "share/doc/survex" directory.
1374
1375  + Default to building for x86_64, since all modern Macs are 64 bit.
1376
1377  + Disable use of liblzma when building wxWidgets for OS X, which was
1378    preventing the build from working on OS X 10.6.8.
1379
1380  + Download wx sources from SF via redirecting link.  Thanks to David A.
1381    Riggs.
1382
1383  + buildmacosx.sh: Handle the mount point for the disk image containing a
1384    space.
1385
1386  + Link with a static build of PROJ for doing coordinate system conversions.
1387
1388  + Build wx with --disable-webview to avoid a compilation failure on OS X
1389    10.10.1.
1390
1391  + Use wx-config --cc and --cxx to get the compilers to use for building
1392    everything else, as wx adds options to them which otherwise cause linking
1393    errors.
1394
1395  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
1396    smaller download.  This means OS X 10.4 is required, but we probably
1397    already need at least 10.5 because that's the minimum version which the
1398    wxWidgets build supports by default.
1399
1400  + Remove unused files and copies of files from the diskimage.
1401
1402* cavern: If the same leg is repeated consecutively, average the readings and
1403  treat as a single leg.
1404
1405* dump3d: Report SEPARATOR used by the file being read.
1406
1407* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
1408
1409* aven:
1410
1411  + Greatly reduce flicker when mouse is moved to the top of the screen in full
1412    screen mode and the menu bar reappears.
1413
1414  + For export formats where scaling is supporting, aven now actually uses the
1415    scale specified in the export dialog (previously it ignored this and used
1416    1:500).
1417
1418  + Reimplement animation so that it's based on angular change per unit of
1419    elapsed time, rather than averaging the time take for the last two scene
1420    redraws.  This gives smoother animation in the face of variable load and
1421    scene redraw time, and should be more consistent between platforms.
1422
1423  + Switching to a point of the compass during auto-rotation now jumps straight
1424    there rather than the two animations fighting.
1425
1426  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
1427    fast.
1428
1429  + Disable stepping the rotation angle when animating (previously we only did
1430    when rotating).
1431
1432  + Speed up start-up a bit - rather than loading icons from individual PNG
1433    files on disk, compile them into the aven binary.
1434
1435* (Unix version): Add "MimeType" field to desktop files so that file
1436  associations work out of the box with modern desktop environments.
1437
1438* Add start of Hungarian translation from Imre Balogh.
1439
1440* Merge in many updates to the Russian translation from "vsuhachev".
1441
1442* Assorted minor updates to other translations.
1443
1444* Create scalable (SVG) versions of file type icons.
1445
1446* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
1447  we're using git.
1448
1449* tests/: Improve test coverage in a few places:
1450
1451  + Extend tests of fore and back sights to test calibration of the back
1452    compass.
1453
1454  + Test "Can't calibrate angular and length quantities together" error.
1455
1456  + Check that "*set names ." works when "." is also the decimal point.
1457
1458Changes in 1.2.16 (2014-10-17):
1459
1460* aven: Add KML export (stations only currently).
1461
1462* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
1463
1464* aven: Fix corrupted names in exported files.
1465
1466* aven: Fix error log window under wxWidgets >= 2.9 to include the system
1467  information before the first log message like it does under wxWidgets 2.8.
1468
1469* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
1470
1471* tests/: Improve test coverage.
1472
1473* Translation updates for many languages, plus the start of translations to
1474  Greek and Polish.
1475
1476* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
1477  by Martin Sluka.
1478
1479* Fix warnings when compiling with clang (which is the default compiler on
1480  Mac OS X).  Reported by Martin Sluka.
1481
1482Changes in 1.2.15 (2014-08-14):
1483
1484* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
1485  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
1486  means that we now support all the coordinates systems which Therion does,
1487  except for a few which don't have X=East and Y=North.  The documentation
1488  for *cs has also been improved.
1489
1490* aven: We no longer persist full screen mode between runs - it's not a
1491  standard behaviour of desktop programs, and it's too easy to go into full
1492  screen mode from the menu and then not be able to get out again because you
1493  don't know the required key shortcut. (ticket#39)
1494
1495* aven: When in full screen mode, moving the mouse to the top of the screen now
1496  makes the menu bar appear.  This provides a non-shortcut way out of full
1497  screen mode, as well as making it easier to perform other operations while in
1498  full screen mode.  The current implementation gives an annoyingly flickery
1499  transition, but hopefully we can improve this in future. (ticket#39)
1500
1501* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
1502  development), we now call EnableFullScreenView() which improves the full
1503  screen mode experience on OS X 10.7 and later.
1504
1505* img library: Improve documentation for img_ERROR_INFO.
1506
1507* tests/: Ship some missing .out files and compare.tst.
1508
1509* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
1510  testcase, and extend it to cover a variant of the situation reported as a bug
1511  in therion by Bill Gee to the therion list.
1512
1513* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
1514  for the survex package and on tk for the svxedit package.
1515
1516Changes in 1.2.14 (2014-07-05):
1517
1518* img library: Add ability to store a PROJ4 string describing the coordinate
1519  system in use in 3d v8 files.
1520
1521* aven: If the 3d file specifies a coordinate system, then use it for exporting
1522  to formats which need to know (currently GPX).  If the input file doesn't
1523  specify the coordinate system, allow the user to enter a PROJ4 string in the
1524  export dialog.
1525
1526* aven: You can now quickly zoom to a particular area by holding down the
1527  "Shift" key and dragging with the left mouse button to create a rectangular
1528  "rubber band box" around the area you wish to zoom to.  If you release the
1529  "Shift" key while still dragging, the box is centred on the start point
1530  rather than having one corner there.
1531
1532* aven: Fix exporting of passage tubes in elevations and extended elevations
1533  - previously up and down were getting drawn across the page!
1534
1535* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1536  1.2.13.  (Reported by Brian Clipstone)
1537
1538* aven: Fix the conditions on which the menu item "Cancel measuring line" is
1539  enabled - previously it was hard to actually cancel it via the menu.
1540  Reported by Hugh St Lawrence.
1541
1542* aven: Fix wx assertion failures when showing hit test debug view on platforms
1543  such as 64-bit Linux.
1544
1545* aven: When viewing from above, show "Plan" above the "clino" which indicates
1546  the tilt angle (instead of "Elevation -90°").
1547
1548* aven: The extended font data now loads faster, and also uses less memory on
1549  64-bit platforms.
1550
1551* aven: Dragging the vertical divider between the side panel and the 3D view
1552  now only updates when you finish the drag, as redrawing continuously just
1553  looks clunky except on an ultra-fast machine.
1554
1555* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
1556  the space available in the aven UI.
1557
1558* cavern: Add a *cs command to allow setting the coordinate system for *fix
1559  commands, and the coordinate system used for processed survey data.  The
1560  latter is now stored in 3d v8 format files.
1561
1562* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
1563  and handle it in the same way as the "DUPLICATE" flag in .svx files.
1564
1565* cavern: If there's more than one *fix command with coordinates, still
1566  actually fix the second and subsequent ones, to avoid triggering bogus errors
1567  about unconnected surveys.
1568
1569* cavern: If there's more than one *fix command with coordinates, report the
1570  station name of the previous one, plus the file and line number where it was.
1571
1572* cavern: Fix handling of the rather contrived case of *fix with no coordinates
1573  followed by *solve and then another *fix with no coordinates not to access
1574  freed memory.
1575
1576* dump3d: Report any specified coordinate system.
1577
1578* doc/3dformat.htm: Update to document how the coordinate system is stored.
1579
1580* (Microsoft Windows version): Include dump3d in the installer.
1581
1582* Fix a compiler warning.
1583
1584* Improve test coverage.
1585
1586Changes in 1.2.13 (2014-05-15):
1587
1588* aven: Fix --print option to wait for printing to happen before exiting
1589  (previously it would exit right after opening the print dialog, so you
1590  couldn't actually print anything out using it).
1591
1592* aven: Increase the threshold for how close the pointer needs to be to a
1593  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
1594  Hugh St Lawrence.
1595
1596* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
1597  if increasing the minimum pointer to station threshold helps Hugh's problems
1598  with using aven on a touch screen device.
1599
1600* aven: The measuring line was unable to see stations which had just been
1601  revealed by toggling surface or underground legs on - this is now fixed.
1602
1603* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
1604  many entries are in each box (toggled by F3).
1605
1606* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
1607  off and back on.
1608
1609* aven: Create the empty hit-test grid data structure lazily, to reduce start
1610  up time a little.
1611
1612* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
1613  and *end commands to instead talk about "survey names".
1614
1615* cavern: For ages cavern has warned if you reentered a survey, but this
1616  warning was suppressed if it occurred at the same line of the same file as
1617  the survey was first entered, but this can only happen if you include the
1618  same survey file more than once, which isn't a sensible thing to do for a
1619  file with actual survey data in (you might reasonably do it to set up survey
1620  grade details or something like that).  The warning is now given in this
1621  situation too.
1622
1623* cavern: After 5 warnings about reentering a survey we give up warning about
1624  it, but we used to keep reporting where the survey was originally entered -
1625  this secondary diagnostic message is now silenced when the main message is.
1626
1627* (Microsoft Windows version): Compile C code with optimisation on.
1628
1629* Add the start of a Russian translation, with messages take from therion.
1630
1631* Minor translation updates to French.
1632
1633* Fix compiler warning from GCC.
1634
1635* Testsuite improvements:
1636
1637  + Test that "..." anon station works.
1638
1639  + cavern.tst: Check number of errors returned by all testcases which should
1640    fail and give an error count.
1641
1642  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
1643
1644Changes in 1.2.12 (2014-04-14):
1645
1646* aven: Fix measuring line to show change in altitude rather than altitude
1647  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
1648  Clipstone.
1649
1650* aven: Fix printing when built with wxWidgets 3.0.
1651
1652* aven: Several visual improvements to printouts:
1653
1654  + Move the numbers below the scale bar down a little so that they don't
1655    overlap the scale bar ticks.
1656
1657  + Set the clipping region after we draw the page border and info box to avoid
1658    clipping the border in print preview.
1659
1660  + Tidy up the appearance of the compass and elevation arrow.
1661
1662* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
1663  <http://bugs.debian.org/739332>.
1664
1665* aven: Fix to build with older libav where avcodec_free_frame() isn't
1666  available.
1667
1668* (Linux version) survex.spec: Update spec file used for building RPM packages.
1669
1670* (Unix version): Add "Keywords:" entry to .desktop files.
1671
1672* (Unix version): Enable large file support, mostly to support filing systems
1673  which return 64 bit inode values, such as CIFS mounts.
1674
1675* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
1676  rather than any character which is a letter in the current locale.
1677
1678* Various translation updates.
1679
1680Changes in 1.2.11 (2014-01-28):
1681
1682* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
1683  Reported by Kevin Dixon.
1684
1685* aven: Embed the font data for the first 256 Unicode characters for use in the
1686  survey pane into the compiled aven binary to reduce start up overhead.  Any
1687  additional characters needed are loaded from a data file only if/when a
1688  character >= U+100 is actually needed (as before).
1689
1690* aven: Fix display of Unicode characters above 256 when there's a character
1691  <= 256 earlier in the same string.
1692
1693* aven: Use the actual width of Unicode characters above 256 rather than
1694  assuming they are 16 pixels wide.
1695
1696* aven: If full screen, don't show the side panel when a new file is opened
1697  (e.g. via Ctrl+O).
1698
1699* aven: Don't give an assertion failure when showing passages for a cave with
1700  no vertical extent.  Reported by Jonny Prouty.
1701
1702* aven: Change terminology in print dialog - say "legend" instead of "info
1703  box".
1704
1705* aven: Add option to show the tilt angle as a percentage gradient.
1706
1707* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
1708  indicators.
1709
1710* aven: All length units are now translatable.
1711
1712* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
1713  will reduce code size and also the number of deprecation warnings about
1714  gluErrorString on Mac OS X 10.9.
1715
1716* (Microsoft Windows version): aven: Try to work around redraw issues related
1717  to the measuring line by redrawing the whole window, which doesn't seem to be
1718  measurably slower.
1719
1720* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
1721  give an error rather than quietly ignoring the attempt.
1722
1723* cad3d: Make cad3d remap control characters and spaces in station names when
1724  generating PLT output in the same way aven does.
1725
1726* Various translation updates (particular thanks to Eric Madelaine and Dennis
1727  Baudys), including the start of a Bulgarian translation, with messages taken
1728  from Therion and elsewhere.
1729
1730* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
1731  GetUserDefaultUILanguage() to get the UI language to use.  For older
1732  versions, continue to use GetUserDefaultLCID().
1733
1734* (Microsoft Windows version): The Indonesian translation will now be used
1735  automatically when the system language is set to Indonesian.
1736
1737* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
1738  A. Riggs for his work on this.
1739
1740* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
1741  checksum check for the downloaded wx sources.
1742
1743* Fix a lot of the compiler warnings when building with clang.
1744
1745* doc/manual.sgml: Add missing quantities to the list documented as accepted by
1746  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
1747  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
1748  mentioned in list of the units that can be set for them); COUNT (missing
1749  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
1750  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
1751
1752* Test suite: Improve test coverage for cavern.
1753
1754Changes in 1.2.10 (2014-01-15):
1755
1756* aven: Fix assertion if two mouse buttons are held down at the same time.
1757  If dragging with more than one mouse button held down, releasing one causes
1758  another which is still held down to take effect.  Reported by Brian
1759  Clipstone.
1760
1761* aven: If we fail to start the external editor when the user clicks on an
1762  error or warning from cavern, show an error box.
1763
1764* aven: If the survey has a title, add it as a top-level <title> element to
1765  exported SVG files.
1766
1767* aven: Escape '<', '>', and '&' in labels in exported SVG files.
1768
1769* aven: In GPX export, set the <time> element to the datestamp from the 3d
1770  file.
1771
1772* aven: Don't try to write the title if it isn't set or is empty when exporting
1773  GPX files.
1774
1775* aven: Don't bother looking up the printer page setup info when exporting.
1776
1777* (Microsoft Windows version): aven: Fix crash on "File->Print" or
1778  "File->Export" under Windows XP, reported by Brian Clipstone.
1779
1780* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
1781  encoded filename which could occur if run without being asked to load a file
1782  on startup.
1783
1784* (Microsoft Windows version): aven: Compile with optimisation on.
1785
1786* img library, aven: Although processed CMAP data files are often referred to
1787  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
1788  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
1789  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
1790  continue to do so in case anyone is relying on it, but also check for the
1791  other extensions.
1792
1793* img library: Add new "datestamp_numeric" field to struct img giving the
1794  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
1795  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
1796  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
1797  timezone wrong.
1798
1799* img library: Fix my_strcasecmp() to handle top-bit set characters better.
1800
1801* cavern: Fix NULL pointer dereference when processing Compass DAT file without
1802  'SURVEY DATE:'.
1803
1804* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
1805
1806* doc/manual.sgml: Note the station length limit Smaps used.
1807
1808* Fix some compiler warnings if built with glibc's fortify source feature
1809  enabled.
1810
1811Changes in 1.2.9 (2014-01-08):
1812
1813* Document --3d-version in cavern man page and the manual.
1814
1815* aven: Fix compilation error in movie export code with recent libavi.
1816
1817* aven: Fix warning on stderr when export a movie as MPEG.
1818
1819* img library: In non-hosted mode, don't define GETC and PUTC if they're
1820  already defined, to allow easy overriding with getc_unlocked() and
1821  putc_unlocked() (which are significantly faster on Linux).
1822
1823* img library: In non-hosted mode, check that int is at least 32 bits,
1824  and if not, use long.  In practice, platforms with 16 bit int are mostly
1825  obsolete, but it's not hard to be portable here.
1826
1827* img library: Add test that img.c and img.h compile in non-hosted mode
1828  (regression test for issue fixed in 1.2.8).
1829
1830* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
1831
1832* Update translations from launchpad and from existing similar messages.
1833
1834* Fix some compiler warnings.
1835
1836Changes in 1.2.8 (2013-10-29):
1837
1838* cavern: Fix handling of anonymous wall stations ('..' by default) to
1839  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
1840  Holder.
1841
1842* cavern: Tweak .err file output not to lose the space in front of certain
1843  statistics when the value gets large.
1844
1845* cavern: Eliminate redundant progress message when solving simultaneous
1846  equations.
1847
1848* aven: Add a format drop down to the export dialog, and only show fields which
1849  are meaningful and supported for the currently selected export format.  The
1850  format defaults to that used most recently.  The "Elements" and "View" boxes
1851  have been swapped in the print and export dialogs as that layout works much
1852  better when the "View" box is hidden.
1853
1854* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
1855  - now works again.  Reported by Anthony Day.
1856
1857* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
1858  this release the projection which the survey coordinates are in defaults
1859  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
1860  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
1861  projection string.  The ability to specify this projection in a better
1862  way is coming soon.
1863
1864* aven: New export options "Origin in centre" and "Full coordinates" - the
1865  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
1866
1867* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
1868  time ago, so update references.
1869
1870* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
1871  with wxMSW 2.9.5.  Reported by Brian Clipstone.
1872
1873* aven: Make right click in an empty presentation mark the current position and
1874  open it to edit, instead of crashing.
1875
1876* aven: Update movie export code to work with latest libav API.  Reported by
1877  Sebastian Ramacher.
1878
1879* aven: Improve reporting of errors during the process of exporting a movie.
1880
1881* aven: Don't try to close the movie if we aren't producing one.
1882
1883* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
1884
1885* aven: Fix to build with wxMSW 2.9.5.
1886
1887* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
1888
1889* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
1890  ago, so add a new --skencil option to specify this output format.  The old
1891  name (--sketch) is still recognised for compatibility.
1892
1893* cad3d: Make --marker-size work for Skencil and SVG output.
1894
1895* dump3d: Make --show-dates option show dates for XSECT.
1896
1897* img library:
1898
1899  + Fix to work once more when used outside of Survex (missing definition of
1900    max() macro and a bad call to free() in img_close() for a file opened for
1901    reading).
1902
1903  + Use lround() instead of round(), and make the tests around whether we use
1904    the library function or the our fallback implementation saner.
1905
1906  + Fix // comments in C code for portability to pre-C99 compilers which don't
1907    support these as an extension.
1908
1909  + Can now be compiled as C++ as well as as C.
1910
1911* (Microsoft Windows version): The installer is now built with a newer version
1912  of Innosetup, and includes translations for all the languages which Survex
1913  itself has any translations for.
1914
1915* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
1916
1917* Minor translation updates.
1918
1919* tests/Makefile.am: Distribute files for "normal_bad" testcase.
1920
1921Changes in 1.2.7 (2013-07-27):
1922
1923* Add support for anonymous stations, which are indicated by one, two or three
1924  separator characters - with the default separator of '.', that means '.',
1925  '..', and '...' are anonymous stations.  Single separator ('.' by default)
1926  is an anonymous non-wall point, double separator ('..' by default)
1927  is an anoymous wall point at the end of an implicit splay), and triple
1928  separator ('...' by default) is an anoymous point (with nothing special about
1929  the leg).  A new *alias command allows '-' to be mapped to '..' for
1930  compatibility with pocket topo: *alias station - ..
1931
1932* New version 8 of the 3d format:
1933
1934  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
1935
1936  + New explicit file-wide flag for 'this is an extended elevation', rather
1937    than modifying the survey title to indicate this.
1938
1939  + The survey prefix is often unchanged from one leg to the next, so use a
1940    spare flag to compactly indicate when there's no label change.
1941
1942  + The data style of each leg is now stored.
1943
1944  + The "processed at" time is stored as seconds since 1970 rather than a
1945    human-readable string.
1946
1947  + Since 3d v8 features significant changes to the format, the format
1948    documentation for v7 and earlier has been split off into 3dformat-old.htm.
1949
1950* img library:
1951
1952  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
1953
1954  + Handle .pos files containing unnamed stations - don't suck the next line in
1955    as the station name, and set img_SFLAG_ANON for them.
1956
1957  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
1958    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
1959    elevation, in place of appending " (extended)" to the title.  Internally we
1960    still append this to the title (and remove it upon reading) when writing
1961    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
1962    explicitly in the file.
1963
1964  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
1965
1966* aven:
1967
1968  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
1969    now, and the wx developers consider even 2.8 to be rather long in the
1970    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
1971    formally dropping support for older versions allows a number of workarounds
1972    to be removed from the aven source code.  Also, features deprecated in
1973    wxWidgets 2.9 are no longer used in our code.
1974
1975  + Don't run incremental search on every key-press, as on a slow machine the
1976    short initial search(es) will take a while but not be useful.  Instead only
1977    actually run the search when we're told there are no more key-presses
1978    queued up.
1979
1980  + Implement support for including cross-section information in exported SVG
1981    and DXF files (ticket#4).  The DXF export is untested currently.
1982
1983  + Show splay legs faded by default, with menu options to hide them or show
1984    them like other legs.
1985
1986  + Speed up loading a .3d file with cross-sections by using a map to convert
1987    station names to positions.
1988
1989  + In the cavern log window, don't highlight a file:linenumber if there's no
1990    message after it, which avoids highlighting the "Included from" lines
1991    wrongly.
1992
1993  + Fix not to crash when trying to report an error while starting up.
1994
1995  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
1996    the OS X standard shortcut Shift-Command-F (previously we used F11, but
1997    that's used by the desktop).
1998
1999  + Add checks for errors when reading the font file.
2000
2001  + Remove useless extra quoting when invoking vim to show the location of an
2002    error from cavern.
2003
2004  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
2005
2006  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2007    in the dialog in sync.
2008
2009* cavern:
2010
2011  + Demote errors about invalid dates to warnings, since we've accepted *date
2012    for ages without any checks on the value, and so existing datasets
2013    probably contain invalid dates and dates in other formats.  (ticket#19)
2014
2015  + New *alias command allows '-' to be mapped to '..' for compatibility with
2016    pocket topo: *alias station - ..
2017
2018  + We want to warn if there's a clino reading which it would be impossible to
2019    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2020    read "93" (it's probably a typo e.g. for "39").  However, the gradient
2021    reading from a topofil is typically in the range 0 to 180, with 90 being
2022    horizontal.  Really we should allow the valid range to be explicitly
2023    specified, but for now we infer it from the zero error - if this is within
2024    45 degrees of 90 then we assume the instrument can read between 0 and 180
2025    degrees.
2026
2027  + If the survey isn't all connected, still run survey tree checks and report
2028    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
2029    Dixon for the report which highlighted this issue.
2030
2031  + Report a warning if *begin SURVEY has a separator character in SURVEY.
2032
2033  + Report column numbers as well as line numbers for some cavern errors and
2034    warnings.
2035
2036  + Adjust width of node stats table to fit longest count when there are more
2037    than 9999 of a particular order of node.
2038
2039  + If the argument to *include has an opening double quote but the closing
2040    double quote is missing, then skip trying to open the file.
2041
2042  + Move "Station X referred to just once" warning after non-existent survey
2043    check - if both fire, the non-existent survey error is likely to be more
2044    relevant.
2045
2046  + We no longer follow an error for a bad reading in passage data with a bogus
2047    "End of line not blank" error, but instead check the remaining readings on
2048    the same line.
2049
2050  + We no longer follow an error about OMIT for a required reading with a bogus
2051    "End of line not blank" error.
2052
2053  + Report an error if the scale factor in *calibrate is zero - it doesn't make
2054    sense and probably means someone reversed the arguments to *calibrate.
2055
2056  + Report the parent include files starting from the outermost, as that's more
2057    logical when there are multiple levels involved.
2058
2059  + If we were expecting a numeric field and instead get something which starts
2060    with '+', '-', or '.' but which isn't a number, then fix the error to
2061    include that character in the token reported.
2062
2063  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2064    first item.
2065
2066* cad3d: Check for errors from img_rewind() and report them.
2067
2068* dump3d:
2069
2070  + Build, install and package dump3d as standard - it's useful for grabbing
2071    info from 3d files in scripts.
2072
2073  + Add --show-dates option.
2074
2075  + Show only 2 decimal places on coordinates and passage dimensions.
2076
2077  + Report the data style of legs.
2078
2079  + Report if the file is an extended elevation.
2080
2081  + Report img_STOP as STOP rather than CODE_0xffffffff.
2082
2083* Test suite:
2084
2085  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2086    expected output so it passes reliably.
2087
2088  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2089    'Deleted' stations upon failure are the more natural way round.
2090
2091  + Add more testcases, expand some existing testcases, and add expected output
2092    for more.
2093
2094* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2095  appropriate C and C++ compilers to use, and link mingw build statically to
2096  avoid needing the libgcc DLL (which newer GCC seems to have by default).
2097
2098* (Unix version): When determining the character set for command-line tools,
2099  check environmental variable LANG after LC_ALL and LC_CTYPE.
2100
2101* When determining the language, check environmental variable LC_ALL before
2102  LC_MESSAGES and LANG (but after SURVEXLANG).
2103
2104* If we don't find the message file, only give an error if it was specified
2105  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
2106  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2107  settings.
2108
2109* There are a handful of hard-coded English message strings for reporting
2110  errors trying loading message files, etc.  These are all now ASCII, as if we
2111  fail trying to open a message file, it's more likely the encoding isn't
2112  set correctly.
2113
2114* Prune strings we are no longer using and are probably unlikely to use again
2115  into a new file po_codes_dead, so that translators don't get presented with
2116  them to translate.
2117
2118* Merge lots of translation updates.  Most translations are now complete or
2119  close to complete.
2120
2121* Add start of Indonesian translation from Arief Setiadi Wibowo.
2122
2123* Fix various compiler warnings when building from source.
2124
2125* Include scripts gdtconvert and gen_img2aven in the source distribution.
2126
2127Changes in 1.2.6 (2012-02-23):
2128
2129* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2130
2131* (Microsoft Windows version): Include JPEG images for aven in the installer
2132  package (ticket#35).
2133
2134* cavern: If we have a reference to a station in a non-existent survey, give a
2135  helpful error rather than saying the station hasn't been exported from the
2136  survey.  (Bug reported by Martin Green via email)
2137
2138* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
2139  Kahler.
2140
2141* findentrances: Add findentrances utility from Olaf Kahler which produces a
2142  .gpx file with waypoints for entrances.  This needs libproj so is disabled
2143  by default for this release - to enable it install the development stuff for
2144  libproj and build survex with:
2145
2146      make FINDENTRANCES=findentrances
2147      make install FINDENTRANCES=findentrances
2148
2149* dump3d: Add support for showing img_ERROR_INFO items.
2150
2151* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2152
2153* Incorporate a French translation from launchpad I'd previously copied the
2154  English version of by mistake.  Attempt to correct mistranslation of "survey
2155  file".
2156
2157Changes in 1.2.5 (2012-01-03):
2158
2159* aven:
2160
2161  + The survey tree in the left panel is now in sorted order once more.
2162
2163  + No longer fails with an assertion if used for a long time (we were leaking
2164    an OpenGL list each time one had to be regenerated).
2165
2166  + Now builds with newer FFmpeg library.
2167
2168  + Draw measuring line in front of the indicators rather than behind them.
2169
2170  + Loading a new file (or reloading the current one) no longer invalidates
2171    the OpenGL lists for the compass and clino, so will be a fraction faster.
2172
2173* Improve handling of attempts to look up translated messages before the
2174  message subsystem is fully initialised (which only happens if there's an
2175  error early on).
2176
2177* Improve the survex(7) man page text, and fix it to be marked as section 7 in
2178  the man page source as well as in the filename.
2179
2180Changes in 1.2.4 (2012-01-01):
2181
2182* aven:
2183
2184  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2185    initialised, which doesn't cause problems in some machines, but causes aven
2186    to abort on others.  This is now fixed, and there's a check in place to
2187    help avoid similar issues in future. (ticket#34)
2188
2189  + Always use metres or feet for the depth colour key, and chose a consistent
2190    precision by looking at the depth range. (ticket#30)
2191
2192  + Show the depth units below the colour bar rather than after every value.
2193
2194  + When zooming way in, stay in metres rather than switching to cm.
2195
2196  + On the scale bar, say “1 mile” rather than “1 miles”.
2197
2198* Translation updates for Catalan, French and Slovak.
2199
2200Changes in 1.2.3 (2011-12-31):
2201
2202* Fix to build with wxWidgets 2.9.2.
2203
2204* (Mac OS X version):
2205
2206  + Processing .svx files from aven now works.
2207
2208  + Remove spurious blank lines from the licence text in "Get Info".
2209
2210  + Don't create the help menu at all, as it is empty (because the "About"
2211    entry goes elsewhere) and sometimes seems to appear in the UI.
2212
2213  + INSTALL.OSX: Update to reflect current status.
2214
2215* aven:
2216
2217  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
2218
2219  + Improvements to text plotted on the survey pane:
2220
2221    - Support plotting Unicode character points > 256 by lazily loading the
2222      data for them from the font file and plotting them with a direct call to
2223      glBitmap(), which is slower but doesn't require a display list per
2224      character.
2225
2226    - Adjust the spacing from fixed width to putting a one pixel gap either
2227      side of each one character (so two between adjacent glyphs).  Mostly this
2228      reduces the horizontal width, but it adds a pixel for characters like "m"
2229      and two in a few cases.
2230
2231    - Fix .pixelfont file generation to correctly handle characters wider than
2232      8 pixels.
2233
2234  + Fix expected cross shape so don't always reject using texture mapping to
2235    draw crosses.
2236
2237  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2238    as those consisting of just one.  Previously we would trip over the empty
2239    tube later.  Such tubes can for example be created by extend if a splay shot
2240    is the start or end of a tube.
2241
2242  + Make the green colour used for entrances in the survey tree the same
2243    (slightly darker than before) green used for the entrance blobs.
2244
2245  + Report the version of the library we're actually running with if built
2246    against wx >= 2.9.2.  Make it clear that the version reported is the
2247    version *built* with for wx < 2.9.2.
2248
2249* extend:
2250
2251  + Copy the end markers for passage tubes.
2252
2253  + Preserve left and right data for tubes (previously they were set to -1.0
2254    which means "no info").
2255
2256* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2257  was no longer used - it certainly is!
2258
2259* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2260  messages, and curly single right quote instead of straight ASCII apostrophe.
2261  Fall back to using straight ASCII versions if we can't represent them in the
2262  current character set.
2263
2264* Translation updates for Catalan, French, Slovak and Spanish.
2265
2266* Test suite:
2267
2268  + Add test coverage for interleaved diving data.
2269
2270  + Add testcase for diving data with topofil-style distance.
2271
2272Changes in 1.2.2 (2011-10-06):
2273
2274* aven:
2275
2276  + Replace the textured-mapped font drawing with an approach based on
2277    glBitmap.  This doesn't suffer from the character alignment issues which
2278    the textured-mapped fonts had, and is actually significantly faster on some
2279    machines.  The current font used is (mostly) fixed-width, but this isn't an
2280    inherent limitation - it was just the easiest font data to convert to a
2281    usable format.
2282
2283  + Fix assertion failure due to rounding differences on loading certain .3d
2284    files.  (ticket#26)
2285
2286  + Fix assertion failure when turning on 3D passages if they stick out higher
2287    or lower than any station.  (ticket#29)
2288
2289  + Fix grid not to disappear when blobs are turned on and blobs are drawn
2290    using lines.
2291
2292  + If a degree sign isn't available in the character set in use, transliterate
2293    it to 'dg' rather than skipping it.
2294
2295  + Fix message which should have been a degree sign but got lost in the format
2296    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
2297    that bearings in the status bar now have a degree sign after them if they
2298    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2299
2300  + Fix print dialog to calculate the scale required for "One page" right
2301    before it calculates how many pages are required, so we don't end up
2302    something other than 1x1 being shown when the user changes settings.
2303
2304  + Update the calculations for picking a scale and for deciding how many
2305    pages are needed to take into account the change in info box height made
2306    in 1.2.1.
2307
2308Changes in 1.2.1 (2011-10-04):
2309
2310* Translation updates for US English.
2311
2312* aven:
2313
2314  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2315    it now shows colours for dates and errors as well as depths.
2316
2317  + In the colour key for "colour by date", change "No info" to "Undated".
2318
2319  + Remove the dark grey background from the colour key and just put a single
2320    pixel black border around the colours.  This is more in keeping with the
2321    other controls, and means the colours are now on a black background so more
2322    visually similar to the survey legs.
2323
2324  + Move the colour key's "Undated"/"Not in loop" entry down a little to
2325    improve the appearance.  Make each section a pixel taller.
2326
2327  + Allow "Colour by X" to be selected even if there's no data for X or only a
2328    single value of X used (the colour key is much smaller in these cases, and
2329    does still provide some useful information).
2330
2331  + Fix incorrect calculation of depth colouring for survey legs which straddle
2332    a depth band boundary.
2333
2334  + The scale bar, compass, clino, and colour key now all have right click
2335    menus which allow related actions to be performed (especially handy in
2336    full-screen mode).
2337
2338  + Improve the font used on the survey pane - it now contains the '-'
2339    character (so the clino now shows negative angles as negative, and dates
2340    in the colour key are now hyphenated).  Also the spacing and alignment
2341    are a little better, though still not perfect.
2342
2343  + PLT file export now handles spaces and control characters in station names
2344    by escaping them with '%' as in URLs.
2345
2346  + Pressing "Enter" on a station in the tree control now centres the view on
2347    that station.
2348
2349  + The scale bar is now cached in an OpenGL display list since it often gets
2350    redrawn exactly the same - for example, when rotating, panning, etc.
2351
2352  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2353    then forces a refresh of the survey pane.  This is intended as a debugging
2354    aid - if pressing F5 changes the display at all then there's a missing case
2355    where a list should have been invalidated (please report if you find such
2356    a case as it is a bug).
2357
2358  + We now automatically track which OpenGL display lists need to be
2359    invalidated on window width or height changes.
2360
2361  + Increase scale bar maximum width from 65% of the window width to 75% as it
2362    was in 1.0.x (except that if that would overlap the clino we now reduce
2363    that proportion down until it reaches 50%).  Make the limit of zooming in
2364    the same as in 1.0.x.  (ticket#23)
2365
2366  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2367    the application was fullscreen (the dialog got opened under the main
2368    window!)  To work around this, aven would switch out of full screen mode
2369    temporarily while showing a dialog.  This case works properly with recent
2370    wxGTK, so disable our workaround with versions we know work.  Also, apply
2371    the workaround only for wxGTK, not everywhere except on Microsoft Windows
2372    as there's no reason to think we need it for other platforms.
2373
2374  + Grey out the "View North" action when we're already viewing North, and
2375    similarly for other compass points.
2376
2377  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
2378    info in the "About" dialog.
2379
2380  + Fix to set the correct filename on the root of the survey tree - previously
2381    the filename of the previous file loaded was used!
2382
2383  + The movie export code now works with newer versions of the FFmpeg libraries
2384    as well as still working with older versions.
2385
2386  + Fix mixed up messages - the print dialog now says "View" on the left
2387    subgroup of controls rather than some unrelated message.
2388
2389  + On printouts, combine the "Plan View"/"Elevation" info box field with the
2390    field which gives the bearing and reduce the height on the info box by the
2391    removed field, so it's now 3cm for plans and elevations, as for extended
2392    elevations.  Report the tilt angle for tilted elevations which it seems has
2393    been missing for ages (it's not in recent 1.0.x either).
2394
2395  + Tweak the exact positioning of informational text on printouts to look
2396    nicer and make better use of the available space.
2397
2398  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
2399    dialog.
2400
2401  + Make the sign of the tilt angle for printouts consistent with the sign
2402    shown by the "clino" in the survey pane.
2403
2404  + In the "Print" dialog, when in plan view disable the "Plan view" button,
2405    and similarly for the "Elevation" button.
2406
2407  + (Microsoft Windows version): Sort out appearance of custom cursors.
2408
2409  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
2410
2411  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
2412    you can't get out again easily, so add code to explicitly check for F11
2413    being pressed and toggle full screen.
2414
2415* (Linux version): Fix the RPM .spec file for where man pages now get installed
2416  and package aven.svg and the vim support files.  (Fixes from James Begley)
2417
2418* "make check" now performs several checks on the translation files.
2419
2420* More messages are now available to be translated.
2421
2422* cavern: Fix reporting of ranges of survey coordinates, which was broken by
2423  the message handling changes in 1.2.0.
2424
2425* Fix warning when compiling with GCC.
2426
2427* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
2428  sudo for installing on Unix.
2429
2430* In the manual, replace the instructions for building from source with a
2431  pointer to the clearer instructions in INSTALL.
2432
2433* In the manual, make it clear that installing with administrator rights
2434  also applies to newer platforms than XP.
2435
2436* doc/TODO.htm: Update.
2437
2438Changes in 1.2.0 (2011-09-20):
2439
2440* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
2441  English.
2442
2443* tests/smoke.tst: aven no longer requires an X display for --help or
2444  --version, so replace skip of this check with a check that this remains the
2445  case.
2446
2447* We now use the standard .po and .pot file formats for storing translations
2448  (rather than the Survex-specific messages.txt format), and then translate
2449  these into Survex's .msg format.
2450
2451* (Unix version): Move survex man page to section 7 (since it isn't documenting
2452  an actual command).
2453
2454* (Unix version): Write each generated man page to a temporary file, then
2455  atomically rename, to avoid leaving an empty or partial man page behind if
2456  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
2457  recurrence of that).
2458
2459* (Unix version): Default to installing docs into /usr/share/doc/survex rather
2460  than /usr/doc/survex.
2461
2462* aven:
2463
2464  + Fix handling of accented characters in the survey pane.
2465
2466  + Aven icon redrawn in SVG format - it's now a vector image which looks
2467    nicer at larger sizes.
2468
2469  + Explicitly request double-buffering, which seems to be needed for systems
2470    with GLX >= 1.3.
2471
2472  + Fix crash while trying to load certain .3d files.
2473
2474  + Movie export code updated to work with more recent versions of FFmpeg.
2475    Currently this is disabled in Microsoft Windows builds, pending getting the
2476    required libraries set up for building releases.
2477
2478  + Reporting of errors during movie export improved.
2479
2480  + Force playback speed to "x1" during movie export.
2481
2482  + Use stock IDs for buttons where appropriate - such buttons may now be
2483    rendered with icons on some platforms.
2484
2485  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
2486    ISO8859-1).
2487
2488  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
2489    as it's no longer required with modern versions.
2490
2491  + Don't redraw the survey on every mouse movement in the survey pane unless
2492    the measuring line is (or just was) active.  (ticket #17)
2493
2494* cavern:
2495
2496  + Drop "non-fatal" from the report of how many errors there were at the end
2497    of the run - it just confuses users - we won't even get here if there's a
2498    fatal error!
2499
2500  + Add --3d-version option to allow the user to specify the version of the 3d
2501    format to output.  (ticket#21)
2502
2503* img library:
2504
2505  + Make the highest and lowest valid values for img_output_version available
2506    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
2507
2508* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
2509  volume actually gets mounted.  Fix URL for downloading wxWidgets.
2510
2511Changes in 1.1.16 (2011-05-16):
2512
2513* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
2514  Portuguese, and US English.
2515
2516* Use horizontal ellipses character rather than '...' and right arrow character
2517  rather than '->' where these characters are available.
2518
2519* (Unix version): Link with -lGL, if it exists, to support linking with gold or
2520  GNU ld --as-needed (Debian bug #615781).
2521
2522* img.c:
2523
2524  + Fix code typo for IMG_API_VERSION == 0 case.
2525
2526  + Fix code typo in code used when IMG_HOSTED isn't defined.
2527
2528* doc/TODO.htm: Remove entries which have now been done.
2529
2530* (Microsoft Windows version): aven: We now include all the available
2531  translations for messages from wxWidgets, which means that standard widgets
2532  will appear translated where available even if Survex messages aren't
2533  translated.
2534
2535Changes in 1.1.15 (2010-10-15):
2536
2537* aven:
2538
2539  + In the cavern log window, change the "Rerun" button to "Reprocess" to
2540    follow terminology in manual and elsewhere.  Fixes ticket#15.
2541
2542  + When displaying output from cavern, don't update the window after every
2543    line, but only when we don't have data from cavern pending.  Hopefully
2544    addresses ticket#12.
2545
2546  + If we aren't using GL_POINTS for blobs, draw them using a series of
2547    abutting lines rather than with gluDisk which is faster and gives a
2548    consistent shape.
2549
2550  + Check whether blobs and crosses actually render correctly as points/point
2551    sprites, and if they don't, fall back to drawing them with lines.  The
2552    best method is cached on disk, and rechecked automatically if the graphics
2553    hardware is changed or the drivers upgraded.
2554
2555  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
2556    though, so we still enable USE_FNT by default).
2557
2558  + Don't offer "All files" wildcard in presentation save dialog.
2559
2560  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
2561    more places.
2562
2563  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
2564    when running cavern from aven.  Fixes ticket#11.
2565
2566* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
2567
2568* diffpos: Handle files with duplicate labels in better - extend generates
2569  duplicate labels when it breaks a loop.
2570
2571* Enable eswap-break testcase now that diffpos handles duplicate station names.
2572
2573* New v7 of .3d format which stores survey dates as number of days since
2574  January 1st 1900, so we now support dates from 1900-2078 (rather than
2575  1970-2037) with a smaller file size.  The img API is now versioned - you
2576  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
2577  gives the survey dates in days in days1 and days2 instead of as time_t
2578  values in date1 and date2.  Fixes ticket#14.
2579
2580* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
2581  former has been the canonical name for some time, with www.survex.com just
2582  redirecting to it.
2583
2584* (Unix version): Use unlocked file I/O if available, which can be much faster
2585  in some cases (we don't need the locking as we don't do multithreaded file
2586  I/O).
2587
2588* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
2589  headers.
2590
2591* (Mac version): buildmacosx.sh now works again.
2592
2593* Most tests weren't actually running any testcases (looks like a sh
2594  portability issue).  This is now fixed, and fortunately all tests still pass.
2595
2596* Include the extra .isl translation files for Innosetup in the source archive.
2597
2598Changes in 1.1.14 (2010-07-26):
2599
2600* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
2601
2602* aven:
2603
2604  + After processing survey data, if there were warnings or errors, add a
2605    "Rerun" button to allow easy reprocessing after fixing problems.  If there
2606    were only warnings, also add an "OK" button to allow moving on to viewing
2607    the processed survey data (fixes ticket#13).
2608
2609  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
2610
2611  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
2612    not the ': ' after), and to make the title for the terminal the
2613    warning/error message.  Avoid false positives by checking that '<line>' is
2614    a number.
2615
2616  + Don't double escape the contents of href and target in links in the cavern
2617    log window.
2618
2619  + Improve handling of the splitter window, fixing behavioural glitches in
2620    various cases.
2621
2622  + Highlight stations matching any current search when a file is loaded.
2623    (ticket#9)
2624
2625  + (Mac version): Fix build issue due to Mac OS X polluting the global
2626    namespace with its own "Point" class.
2627
2628  + (Unix version): The Gnome print dialog has its own preview window so
2629    suppress ours if using the Gnome one.
2630
2631  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
2632
2633  + (Microsoft Windows version): Fix handling of a double-click on the survey
2634    tree when built with wxWidgets >= 2.8.11.
2635
2636* cavern: Report relevant file and line number for three warnings which didn't
2637  give them before.
2638
2639* (Unix and Mac versions): configure: Update the wx-config probing code -
2640  wxmac-config etc aren't present with newer wxWidgets versions so there's no
2641  point looking for them now.
2642
2643* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
2644  for easy installation.  Update it to work with the latest Survex versions
2645  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
2646  private wxWidgets, use 2.8.11 not 2.7.0-1).
2647
2648* manual:
2649
2650  + Correctly capitalise "GTK".
2651
2652  + Note that on Linux we only regularly test builds with the GTK+ version
2653    (change taken from 1.0).
2654
2655* Fixed the cad3d man page, which was an empty file in 1.1.13.
2656
2657Changes in 1.1.13 (2010-06-16):
2658
2659* Say "wxWidgets" instead of "wxWindows" consistently.
2660
2661* img.c: Fix small memory leak (filename_opened member).
2662
2663* cad3d, aven: Fix export to SVG when a label contains a '%' character.
2664
2665* aven:
2666
2667  + wxWidgets 2.6.0 or newer is now required.
2668
2669  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
2670    work but hasn't been tested recently (all packaged versions of wxWidgets
2671    seem to be Unicode now).
2672
2673  + Fix potential uses of uninitialised variables which may have been causing
2674    occasional glitches when loading a file on start-up.
2675
2676  + Improvements to the handling of the font used for plotting labels and other
2677    text on the survey pane:
2678
2679    - Loading the font file is more efficient.
2680
2681    - Character spacing is improved.
2682
2683    - Default font is now anti-aliased.
2684
2685  + "About" dialog:
2686
2687    - Add "Copy" button to copy the system info to the clipboard for easier
2688      bug reporting.
2689
2690    - List OpenGL extensions last, since there are usually lots of them with a
2691      modern gfx card.
2692
2693    - Fix 100% CPU usage while the "About" dialog is open.
2694
2695  + Processing .svx files:
2696
2697    - Passing a .svx file on the command line now works better.
2698
2699    - Put the survey data log window in a splitter in the usual frame rather
2700      than opening a separate frame for it.
2701
2702    - Auto-scroll the log window until we've reported a warning or error.
2703
2704    - Fix small memory leak.
2705
2706  + The presentation filename now defaults to using the basename of the
2707    currently loaded dataset, but we always prompt before we first save with
2708    such a name.
2709
2710  + Reduce memory usage when saving a screenshot.
2711
2712  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
2713    persist the window size (and maximised or fullscreen state) between
2714    invocations.
2715
2716  + Fix reporting of OpenGL errors.
2717
2718  + Fix glitches when tilting while looking East.
2719
2720  + Added Portuguese and Slovak translations of wxWidgets messages.
2721
2722* Documentation:
2723
2724  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
2725
2726  + Drop the "alternative manual formats" self-extracting zip file - people
2727    will generally just want one of the formats, so downloading several
2728    together isn't very useful.
2729
2730  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
2731
2732  + GPL.htm: Replace HTML version of licence with a link to the version on
2733    the FSF website.
2734
2735  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
2736    low level to be of interest to non-developers, and developers can look at
2737    the source code.
2738
2739* (Unix version): configure: New preferred name for specifying wx-config script
2740  is WX_CONFIG.  WXCONFIG still supported for compatibility.
2741
2742* (Linux version): Source RPM package dropped as you can just build an RPM
2743  package from the source tarball.
2744
2745* (Microsoft Windows version): The installer is now created with a newer
2746  version of InnoSetup, which gives a 10% smaller download.
2747
2748Changes in 1.1.12 (2007-02-07):
2749
2750* aven:
2751
2752  + Remember the window size or maximised/fullscreen state between invocations.
2753
2754  + Add options dialog to "Export" similar to the one for "Print".
2755
2756  + The "number of pages required" in the print dialog now updates when you
2757    change what is to be shown (underground legs/surface legs/station
2758    names/crosses).
2759
2760Changes in 1.1.11 (2006-11-25):
2761
2762* Updated Czech, Spanish, and Slovak translations.
2763
2764* (MacOS X version): Assorted OS X specific tweaks and fixes.
2765
2766* aven:
2767
2768  + Pick a smaller and clearer font for labels.
2769
2770  + Fix character spacing.
2771
2772  + Tweak display of bearing and elevation angles to look nicer with
2773    proportional fonts.
2774
2775  + Use the title from the 3d (or plt, etc) file for the window title
2776    rather than the filename.
2777
2778  + Show distances to 2 decimal places rather than the nearest integer.
2779
2780  + Only consider underground legs when calculating the depth bands and
2781    depth colouring.
2782
2783  + Add "Colour by Error".
2784
2785  + Add entry for "white" in date and error keys.
2786
2787  + When setting the view to a single point, don't change the scale.
2788
2789  + If reloading the same file, don't change the view
2790
2791  + Fix filetypes selector in open dialog.
2792
2793  + Fix the charset we use for aven in certain cases.
2794
2795  + Call msg_init before using msg_lang or it won't ever be set!
2796
2797  + Pass wx the full language code to initialise the C library locale.
2798
2799  + Fix bug in generating prefix tree view which could lead to a bogus
2800    leading dot on some survey names (bug probably introduced in 1.1.10).
2801
2802  + "New Presentation" now ensures that the side panel is open
2803
2804  + Fix updating of cached opengl lists when the view is reset to the
2805    default.
2806
2807* Ignore LANG if it starts with a digit to avoid problems with bogus value for
2808  LANG which AutoCAD installation seems to set on MS Windows.
2809
2810* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
2811  specified.  Either/both can be set to ":".
2812
2813* dump3d: Report unknown (to dump3d) codes returned by img.
2814
2815* img library: Flag all stations as underground in the old "ASCII" .3d format.
2816
2817Changes in 1.1.10 (2006-07-14):
2818
2819* aven: Clicking on a survey name in the survey tree now highlights it in
2820  the map view.  Double-clicking zooms the view to show the clicked survey
2821  highlighted.  Clicking the root clears the highlighting and double-clicking
2822  the root restores the default view.  To expand/collapse a branch, click
2823  on the "[+]" or "[-]" icon to the left of the survey name.
2824
2825* aven: The measuring line can now measure to anywhere in plan or elevation
2826  view (not just to a station!)  In plan view the horizontal distance and
2827  bearing are shown, while in elevation view the vertical distance is shown.
2828
2829* aven: Moving the mouse over a station in the survey view now highlights
2830  that station in the survey tree (though it may not be visible if the
2831  survey(s) it is in aren't expanded).
2832
2833* aven: Clicking on a station to centre the view now moves the mouse pointer
2834  to the new location of the station (except on Mac OS X where this isn't
2835  allowed).
2836
2837* aven: Fix which presentation toolbar buttons are shown as depressed.
2838
2839* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
2840
2841* vim files are now installed with the correct paths (bug introduced in 1.1.9).
2842
2843Changes in 1.1.9 (2006-07-04):
2844
2845* (Unix version): Install desktop files for aven and svxedit contributed to the
2846  Ubuntu package by Phil Bull, and corresponding pixmaps.
2847
2848* Fix img to filter out cross-sections which don't match the subsurvey (if
2849  specified).  The API now returns img_XSECT_END to mark the end of a
2850  passage rather than setting a flag on the last img_XSECT of the passage.
2851
2852* Enhance integration with the vim editor - this can now colour .err files, run
2853  cavern from vim and parse error output, and run aven from vim.  Tweak the
2854  existing vim mode for .svx files to fix a few minor bugs and add support for
2855  the new "*data passage" style.
2856
2857* aven: fix drawing of the "blob" end of the measuring line on graphics cards
2858  which can't draw large enough blobs for us.
2859
2860* aven: sort out confusion about what encoding everything is in which means
2861  that the distance measured by the measuring line actually gets displayed
2862  and also fixes problems with empty menu items in non-English locales in
2863  some cases.
2864
2865* aven: redraw grey background after a menu is closed over the aven window
2866  with no survey loaded.
2867
2868* aven: fix bug which caused printing to crash (introduced in 1.1.8).
2869
2870* aven: avoid crash on some machines when opening "About" dialog before having
2871  loaded a survey.
2872
2873* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
2874
2875* (Unix version): aven: Fix character set handling of cavern output.
2876
2877* cavern: Report an error if a cross-section is specified for a station which
2878  doesn't exist.
2879
2880* Updated French and Italian translations.
2881
2882* (Unix version): aven: Fix "Can't open message file `en_US' using path
2883  `${prefix}/share/survex'" error.
2884
2885* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
2886  (doesn't affect Survex itself, but other applications which use img.c should
2887  update their copy).
2888
2889* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
2890  and later are caught by configure, whereas older wx versions are caught when
2891  trying to compile).
2892
2893Changes in 1.1.8 (2006.06.30):
2894
2895* Drop support for building with wxWidgets versions prior to 2.4.0
2896  (which was released on 2003-01-07).
2897
2898* aven: Printing through aven now uses settings from the "[aven]" section
2899  of print.ini, and support for hierarchical sections (using "like=")
2900  has been disabled.
2901
2902* aven: Change mouse actions to be compatible with those in Survex 1.0.
2903  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
2904  left drag is now smart about not rotating and zooming at the same
2905  time.
2906
2907* aven: Highlighting stations now happens as you type, and pressing
2908  "Enter" or clicking the "Find" button now pans and zooms to show the
2909  highlighted stations.
2910
2911* aven: Left-clicking away from a station now cancels measuring line.
2912
2913* aven: Setting view to North, South, East, or West is now animated like
2914  the tilt from plan to elevation.
2915
2916* aven: Fix presentation saving to also write "." for decimal points and
2917  presentation loading to accept either "." or ",".
2918
2919* (Unix version): aven: Add text for all toolbar items so that aven
2920  will work with the Gnome desktop preference for displaying toolbars as
2921  icons with text or just text (wxWidgets needs fixing first though).
2922
2923* (Unix version): aven: Remove the ability to detach the menu bar (yell
2924  if you actually used it and I'll restore it!)
2925
2926* aven: Add "all survey files" option to the "open file" dialog.
2927
2928* (MS Windows version): aven: Fix cursor keys to pan survey.
2929
2930* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
2931
2932* (MS Windows version): Fix installer to work on Windows 2000 or XP if
2933  run by an unprivileged user.
2934
2935* (MS Windows version): Upgrade to the latest version of InnoSetup (the
2936  installer builder we use) and include new installer translations for
2937  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
2938
2939* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
2940  translations of messages for wxWidgets (the GUI library we use).
2941
2942* aven: Disable "Highlight exported points" if there aren't any.
2943
2944* Updates to French translation from Michel Bovey.  Also updates to German,
2945  Italian, Catalan, Spanish, and Romanian translations.
2946
2947* (Unix version): test suite: fix smoke test to pass even without X running
2948  (it was meant to but the code had a bug).
2949
2950* aven: Check if OpenGL is available and exit cleanly with a helpful error
2951  if it isn't.
2952
2953* (Unix version): aven: Fix --help and --version to work without a working
2954  X display (provided it's built with wxWidgets 2.5.1 or newer).
2955
2956* aven: Automatically select the presentation tab of the notebook when the user
2957  selects "New Presentation" or "Open Presentation".
2958
2959* aven: Fix "Delete" in the presentation list to not get passed on (and so not
2960  reset to default view as well).
2961
2962* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
2963  empty.
2964
2965* aven: Fix Cursor Up and Down in the presentation list to move the highlight
2966  up and down instead of being passed on and moving the survey.
2967
2968* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
2969  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
2970  Safari 2.0.3, and InkScape 0.42.
2971
2972* aven: Put a 5mm border around exported SVG files to allow for station markers
2973  and non-zero width lines.
2974
2975* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
2976  was turned on.
2977
2978* aven: Actually close the file we're exporting which fixes problems with it
2979  not always being fully written.
2980
2981Changes in 1.1.7 (2005.10.18):
2982
2983* cavern: Add validity checking for dates in *date commands (with feature
2984  test in testsuite).  A date entered as just "year" or "year.month" now
2985  becomes a date range for the relevant period (previously it became a single
2986  date near the middle of that period).
2987
2988* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
2989  with MS Windows).
2990
2991* extend: Default output name for a file called input.3d is now input_extend.3d
2992  rather than just extend.3d (which was annoying if you wanted to extend
2993  several surveys in the same directory).
2994
2995* aven: OpenGL 2.0 always includes support for point sprites so rework
2996  our check for them to include that knowledge.
2997
2998* aven: Regenerate depth bar if user switches to/from metric units.
2999
3000* aven: Don't clear the "there" mark just because the mouse pointer has
3001  moved off a station.
3002
3003* aven: When processing a .svx file, put the resultant .3d file in the
3004  same directory (since that's where we then try to load it from).
3005
3006* aven: Fix labelling of date colouring on 32 bit platforms.
3007
3008* aven: If "colour by date" is on and we load a survey with no date info
3009  (or all surveyed on the same date) then set "colour by none".
3010
3011* aven: Make the error dialog modal and remove a signal handler once it
3012  has fired to prevent endless (or seemingly endless) cascades of error
3013  dialogs.
3014
3015* aven: Enforce a minimum object volume diameter of 1m to avoid problems
3016  if a survey file with only one station in is loaded.
3017
3018* aven: Fix problems with indicators disappearing when we're drawing
3019  blobs and/or crosses the slow (but always supported) way.  (Problem
3020  introduced in 1.1.6).
3021
3022* (Unix version): aven: Really stop setting extra toolbar margin when using
3023  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3024  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3025
3026* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3027  we've been compiled with, and which GTK+/Motif version where appropriate.
3028
3029* (Unix version): Fixed build on Fedora Core 3.
3030
3031* documentation: Updates to 3d file format specification from Mike McCombe.
3032
3033Changes in 1.1.6 (2005.10.10):
3034
3035* (MS Windows version): Distribution is about a third smaller than 1.1.5
3036  (mostly because mingwm10.dll is no longer required).
3037
3038* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3039  it, showing cavern's output in a window (with errors and warnings clickable
3040  to load the offending file into an editor), and then loading the resulting
3041  3d file.
3042
3043* aven: Added "Colour by Date" option.
3044
3045* aven: Disable "Colour by Depth" option if there's no elevation variation.
3046
3047* aven: Don't crash if trying to load a survey with no elevation variation.
3048  Instead turn off depth colouring.
3049
3050* aven: Export as HPGL added.
3051
3052* aven: Improved update of mouse coordinates and measuring line (thanks to
3053  Martin Green).
3054
3055* aven: Show the coordinates of either the mouse pointer or the nearest
3056  survey station to it (if there is one near enough).  Showing both was
3057  confusing and meant the status bar overflowed on smaller displays.
3058
3059* aven: When printing an extended elevation, don't show bearing and elevation.
3060
3061* aven: Don't lock "flat" surveys which aren't extended elevations - a
3062  flat survey with LRUD data isn't flat any more!
3063
3064* aven: When we have to draw blobs and crosses the slow way (because the
3065  graphics hardware doesn't support the fast way), draw them so that they
3066  should appear at the correct depth into the 3D scene instead of on top
3067  of everything else.
3068
3069* aven: Make "play presentation backwards" icon green to match the other
3070  presentation icons.
3071
3072* (MS Windows version): aven: Mouse clicks on the survey view now set the
3073  keyboard focus there.
3074
3075* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3076
3077* (MS Windows version): aven: Fix redrawing of measuring line.
3078
3079* cavern: Store dates for img_XSECT.
3080
3081* cavern: Fixed small one-off memory leak if you specify -o more than once.
3082
3083* (Unix version): Check environmental variable LC_MESSAGES when deciding what
3084  language to use for messages.
3085
3086* (MS Windows version): "Print" on a 3d file now prints through aven rather
3087  than the separate printer driver (Unix has done this for some time).
3088
3089* Removed old printer drivers.
3090
3091* img library: When creating a 3d file, ignore img_XSECT if we've been asked
3092  to write a file format version which doesn't support it.
3093
3094Changes in 1.1.5 (2005.09.20):
3095
3096* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3097
3098* aven: Make blobs round like they are in Survex 1.0.
3099
3100* aven: If the graphics drivers don't support drawing blobs using OpenGL
3101  point markers, fall back to drawing filled circles.
3102
3103* aven: If the graphics drivers support it, draw crosses as texture mapped
3104  OpenGL point markers which is much faster.
3105
3106* aven: Cross size increased to match Survex 1.0.
3107
3108* aven: We must update which blobs are displayed if display of surface or
3109  underground legs is toggled.
3110
3111* cavern: Fix handling of a *solve followed by survey data, none of which is
3112  attached to the previous data.
3113
3114* cavern: Fixed "No survey data" error when a *solve is followed by another
3115  *solve (or the implicit solve at the end of processing) with no data between
3116  them.
3117
3118Changes in 1.1.4 (2005.09.19):
3119
3120* aven: Added Aven's icon to the "About" dialog.
3121
3122* aven: Use localised character for the decimal point (e.g. "," in most
3123  continental European countries).
3124
3125* aven: Previously the survey tree would get focus and then take keypresses
3126  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
3127  operate on the cave, and transfer the input focus across when we do.
3128
3129* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3130
3131* aven: Speed up intialisation by delaying creation of OpenGL lists until
3132  they're needed.
3133
3134* aven: Added Mark Shinwell's bounding box with shadow of the survey.
3135
3136* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3137
3138* aven: Reworded "Restore Default Settings" as "Restore Default View".
3139
3140* (Unix version): aven: Set sensible default margins for printing and preserve
3141  any margin values the user specifies between runs (previously margins
3142  defaulted to 0 each time aven was run).
3143
3144* Documentation: Document *DATA PASSAGE in the manual.
3145
3146Changes in 1.1.3 (2005.09.07):
3147
3148* (Microsoft Windows version): Fixed build problems.
3149
3150* cavern: Allow OMIT character (-) for left/right/up/down.
3151
3152* aven: Remove an unnecessary menu separator.
3153
3154* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3155
3156* aven: Make the tooltip for "Hide" show the number of found stations.
3157
3158* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3159
3160* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3161  when there's a presentation loaded.
3162
3163* aven: Make entrances green in side panel tree list to match green blobs used
3164  in cave view.
3165
3166* aven: Don't show surface labels if we're not showing surface data, etc.
3167
3168* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3169  make "Space" the key for this.  Keep Return working "Stop Rotation" so
3170  existing users are happy, but don't advertise it.
3171
3172* aven: Normalise filename by adding any extension used, and use the normalised
3173  filename for file history and window title.
3174
3175* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3176  as the toolbar buttons already have a sensible margin - the extra margin is
3177  only needed with GTK1.2.
3178
3179* aven: Fix handling of plumb legs in tube model.
3180
3181* aven: Fixed swapped L and R in tube model.
3182
3183* extend: Preserve UD cross-section information in extended elevation.
3184
3185* extend: Add new messages for John Pybus' enhancements.
3186
3187Changes in 1.1.2 (never formally released):
3188
3189* Added support for LRUD data in .svx files, in .3d files, and aven can
3190  now load and display it on screen and on printouts.  The ability to "fake"
3191  LRUD data in aven is gone for now but will reappear in some form later.
3192
3193* cavern: Removed support for writing Chasm's 3dx format.  We're going to
3194  fold any desirable missing chasm functionality into aven.
3195
3196* aven: Rearranged mouse actions as discussed on the mailing list.  Added
3197  cursors for each different mouse action to help the user learn what each
3198  does.  Also added cursors for the "compass" and "clino" as well as the
3199  scalebar to suggest to the user that they can be dragged to change the view.
3200
3201* (Unix version): aven: Don't segfault if LANG isn't a known language.
3202
3203* tests/smoketest.tst: If X windows is running, check that we can run aven
3204  with --help and --version.
3205
3206* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3207  no results are listed for it.  This revealed that there was a "newline" test
3208  which should have been called "badnewline", and was a broken testcase too!
3209  Fixed all these problems.
3210
3211* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3212  and omitted forward compass/clino readings in Compass DAT files.  Added
3213  a feature test for this to the testsuite.
3214
3215* It no longer makes sense to have an option not to build aven or to build aven
3216  without OpenGL so remove old machinery for this from configure and the
3217  sources.
3218
3219* (Unix version): configure: Check if "-lXxf86vm" is needed.
3220
3221* configure: Better output for strcasecmp test.
3222
3223* aven: Fix crosses to work much better.  Not a total fix - their position
3224  in the Z buffer isn't correct and they're rather slow to plot.
3225
3226* aven: Don't regenerate the hittest grid every time the mouse moves while
3227  animating, which solves the mysterious pausing effect (thanks go to Martin
3228  Green for spotting this!)  Also clear all the status bar coordinates when
3229  animating.
3230
3231* aven: Sort out clashing menu shortcuts in some languages.
3232
3233* aven: Fixed compilation problem on x86_64
3234
3235* SPUD: Pruned out stuff which has been done or which is not actually relevant
3236  to this branch.
3237
3238* Merge various changes from 1.0 branch:
3239
3240  + aven: Port over "printing from aven" functionality.
3241
3242  + aven: Port over "export as" functionality,
3243
3244  + Add David Loeffler's vim mode for .svx files.
3245
3246* aven: Fix check for whether a label is behind us in perspective view.
3247
3248* aven: Don't use an opengl list for drawing the indicators - we typically make
3249  a new list each time we plot them anyway.
3250
3251* Remove lingering traces of support for RISC OS and pre-386 MSDOS
3252
3253* aven: Set icon on non-Windows platforms too.  This means that with
3254  WindowMaker on Unix you get an icon on the AppIcon by default.
3255
3256* configure: Update wxWindows checks to handle newer wx versions.
3257
3258* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3259  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
3260  for anyone building from CVS).
3261
3262* acinclude.m4: Quote macro name for fix autotools warning.
3263
3264* Documentation: "tilt up" is "'" not ",".
3265
3266* aven: Add support for mousewheels (to tilt the cave).
3267
3268* aven: Fixed twisted transitions to and from pitches in certain cases.
3269
3270* aven: Pick a sensible initial window size when the user's desktop is spread
3271  over more than one monitor (works best with wx2.5 or newer, but try to do
3272  better with wx2.4 or earlier as well).
3273
3274* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3275  contents being visible before any survey is loaded.
3276
3277* aven: Allow a coloured texture to be used
3278
3279* aven: Don't initialise until we have data (to the user, this means the window
3280  is default colour (grey for most systems) not black until a survey is
3281  loaded).
3282
3283* aven: Fixed weird "shadowed" icons.
3284
3285Changes in 1.1.1 (2004-10-06):
3286
3287* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
3288  startup.
3289
3290* aven: Delay loading the bitmap for the "About" dialog until it is first
3291  needed.  We want start up to be as quick as possible.
3292
3293Changes between 1.0.32 and 1.1.0 (never formally released):
3294
3295* NOTE: Survex 1.1.X releases are development snapshots made available for
3296  the purposes of allowing wider testing and getting more user feedback.  Once
3297  the code has stabilised the version number will be raised to 1.2.0.
3298
3299* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3300  you're using Windows 95 - these can be obtained from:
3301  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
3302
3303* aven: Solid passages - passage dimensions are currently inferred from
3304  the leg length (pretty effective as you can measure longer legs in
3305  larger passages).  Use of real LRUD data coming soon...
3306
3307* aven: Depth colouring is now continuously varying.
3308
3309* aven: Colour by depth can now be turned off (and there's the start of a
3310  framework for properly implementing colour by date, error, etc).
3311
3312* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3313  match (? matches any character, * matches any number of characters).
3314
3315* aven: We now use the status bar for coordinates, distances, etc to make
3316  better use of screen space.
3317
3318* aven: Full screen mode (F11).
3319
3320* aven: Perspective view.
3321
3322* aven: Context sensitive cursor shape - needs more work.
3323
3324* aven: Mouse actions changed (hopefully they're now more natural, but
3325  you may find the change disorientating - feedback wanted on this).
3326
3327* aven: Added "presentations" which allow you to set up fly-through paths
3328  and load/save/run them.
3329
3330* aven: A presentation can be exported as a movie file.
3331
3332* aven: Added Save screenshot facility.
3333
3334* aven: Depth fogging option.
3335
3336* aven: Added Smooth Lines option.
3337
3338* aven: Added Textured Walls option.
3339
3340* aven: If a survey has surface legs but no underground legs, default to
3341  showing the surface legs.
3342
3343* cavern: Dates given to *date are now stored in the 3d file.
Note: See TracBrowser for help on using the repository browser.
