1Changes in 1.2.42 (2019-09-04):
2
3* aven:
4
5  + Allow colouring by horizontal or vertical error.
6
7  + (Unix version): Disable scaling for HiDPI displays with GTK3.  The OpenGL
8    code needs work before this will work usefully, so just disable for now
9    (which simulates how things are when using GTK2).
10
11  + (Unix version): Fix orientation of notebook tabs when build with wxWidgets
12    3.1 development versions.  We want horizontal tab orientation, but were
13    passing a weird flag combination which now results in vertical tab
14    orientation.
15
16* When exporting to a format where we support rotation in the horizontal
17  plane (such as SVG), the rotation was incorrectly applied to cross section
18  data (except for the default rotation of zero).  Fixes #108, reported by
19  Richard Knapp.
20
21* Add a section to the manual covering the command line tools, and what you
22  might still need to use them for.
23
24* Fix compiler warning when building from source with GCC 9.
25
26* Consistently refer to macOS not OS X - Apple have renamed it yet again.
27
28* (macOS version): Revert the workaround for the crash on macOS 10.14.  The
29  bug we were working around is fixed in git ready for wxWidgets 3.0.5 and
30  there's a backported fix in the homebrew wxmac 3.0.4-2 package, which is how
31  we now recommend people install on a Mac.  Closes #101, reported by floho.
32
33* (macOS version): Remove buildmacosx.sh script since installing from homebrew
34  is now the recommended approach.
35
36Changes in 1.2.41 (2019-07-10):
37
38* aven:
39
40  + (Microsoft Windows version): Fix error on startup in the pre-built version
41    of 1.2.39 and 1.2.40.  This is a recurrence of the same issue as affected
42    1.2.33 - this time I've patched out the unnecessary check in wxWidgets
43    which causes this problem so it shouldn't recur again.  Reported by
44    Brian Clipstone.
45
46  + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
47    as I don't have access to a Mac).  Hopefully fixed #101, reported by floho.
48
49Changes in 1.2.40 (2019-07-04):
50
51* aven: Draw the measuring line ring with an even shape.  Previously the exact
52  shape of the ring varied slightly depending on the exact coordinates, which
53  could be visually distracting once you noticed it.
54
55* We were casting a function pointer with a bool return type to the same type
56  but with a void return type.  In practice this probably works fine on most
57  platforms, but it's undefined behaviour and also gives a compiler warning
58  with some compilers.
59
60* Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
61  installed.
62
63Changes in 1.2.39 (2019-06-29):
64
65* Support versions 5.x and 6.x of the PROJ library we use for handling
66  conversions between coordinate systems.  Reported by Bas Couwenberg
67  in #102, by Richard Knapp in #103 and by Martin Sluka in email.
68
69* (Unix and Mac OS versions): When checking if something is a file or if it is
70  a directory, we no longer treat a symlink as being neither, but instead
71  return an answer based on what the symlink points to.
72
73* aven:
74
75  + Improve handling of hidden splay ends.  Previously, hidden splay ends still
76    served as "targets" for snapping the mouse pointer to, and still got
77    crosses when crosses were enabled.  We don't have a handy flag for "this is
78    the outer end of a splay" and computing that on demand isn't so easy to do,
79    so for now we use the "anonymous station" flag so at least these cases now
80    behave properly for splays to anonymous stations (which is likely to be
81    what people with huge numbers of splays from disto-x, etc are using).  This
82    does mean that anonymous stations on continuation passages will incorrectly
83    also be off when splays are hidden, but that seems an OK trade-off for now
84    and a definite improvement over the previous situation.  The snapping of
85    the mouse pointer was reported by Frank Tully in #105.
86
87  + Fix typo in export UI (CVS should be CSV).
88
89* Documentation:
90
91  + Add CSV to documented list of survexport output formats.
92
93  + Fix *declination syntax synopsis - "auto" is a literal string, not a
94    placeholder.
95
96  + Update PROJ project name and website - the name is now "PROJ" (all caps and
97    no ".4" suffix) and the website is now: https://proj.org/
98
99* Install gtksourceview-3.0 language file so .svx files now get syntax
100  highlighting in gedit and other GtkSourceView-based editors.  Patch
101  from Philip Withnall.  Fixes #98.
102
103* (Microsoft Windows version): The Survex installer doesn't uninstall the old
104  version when you upgrade, but just overwrites it with the new version.  In
105  1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
106  an older version would still have cad3d.exe from that old version.  We now
107  remove any old cad3d.exe left over from a previous install in the same
108  location to avoid confusion.
109
110* Add a few more message translations.
111
112* Fix warnings when built with a C++11 compiler.
113
114Changes in 1.2.38 (2019-03-02):
115
116* cavern:
117
118  + Deprecate MILS as angular units.  Survex has long support MILS as an alias
119    for GRADS.  However, this seems to be a bogus definition of a "mil" which
120    is unique to Survex (except that Therion has since copied it) - there are
121    several different definitions of a "mil" but they vary from 6000 to 6400 in
122    a full circle, not 400.  Reported by Andy Edwards.
123
124  + Fix segfault for *include "".  This isn't useful, but shouldn't crash.  It
125    now reports "file not found" instead.
126
127  + Use isnan() to check for not-a-number.  This is cleaner, more robust and
128    more efficient than formatting the number as a string and checking for
129    "NaN" or "nan" in the result.
130
131* Avoid unused variable warning when compiling from source with modern ffmpeg.
132
133* Drop support for wxWidgets < 3.0.  3.0.0 was released over 5 years ago and
134  should be easily available everywhere by now.  I'm no longer easily able to
135  test with wxWidgets 2.8, and this allows a significant amount of cruft to be
136  removed.
137
138* (Linux version): survex.spec: Fedora have removed gcc from the default build
139  environment so need to explicitly list it in the BuildRequires tag.  See
140  https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
141  information.  Patch from James Begley.
142
143Changes in 1.2.37 (2018-11-18):
144
145* aven:
146
147  + Add basic "Colour by Survey" feature.  The colours used aren't currently
148    controllable.
149
150  + Fix export of splays.  Patch from Thomas Holder.
151
152  + Fix KML export to avoid invalid geometry when a tube intersects itself.
153    Patch from Robert Jones.
154
155  + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
156    for now.  This is a workaround until wxWidgets OpenGL support is updated
157    to work under Wayland.  Reported by Philip Balister.
158
159  + Fix warnings about using deprecated functions when building movie export
160    code using FFmpeg 4.0.
161
162* cavern:
163
164  + Compass MAK files: Handle fixed point coordinates in feet - previously the
165    units were ignored and the coordinates assumed to be in metres.
166
167  + Previously the first byte in a MAK file was ignored.  Typically MAK files
168    start with a comment, and since cavern currently ignores lines that start
169    with characters it doesn't understand the meaning of, this bug would often
170    go unnoticed.
171
172* survexport:
173
174  + Fix exporting of passages, walls and cross-sections by running the code
175    aven uses to decide how much to rotate each cross-section.  Previously all
176    cross-sections were aligned West-East.  Reported by Robert Jones.
177
178  + Default to .pos output if the program name is 3dtopos, and install a second
179    copy (or hardlink under Unix) as 3dtopos.  This provides compatibility with
180    current releases of Tunnel.  Reported by Becka Lawson, Wookey and
181    Stephen Crabtree.
182
183* Fix some German translations.  Patch from Thomas Holder.
184
185* (MacOS X version): Fix aven-create-app to not delete converted icons.
186  Typo spotted by Robert Jones.
187
188* Improve documentation for *team.  Document the requirement to quote names
189  unless a person is identified by just one name.  Document that the roles are
190  optional, as that information may not have been recorded, and to align with
191  therion's team command.
192
193Changes in 1.2.36 (2018-07-18):
194
195* aven:
196
197  + Add support for exporting as a CSV (Comma-Separated Values) file.
198
199  + Support exporting KML with altitude mode "clamp to ground".  In this mode,
200    the altitude in the data is ignored and it's rendered on the surface of the
201    terrain.  This is useful if your KML viewer renders the terrain as opaque
202    so underground data isn't visible.  Rendering cave passages on the surface
203    isn't great, but is better than not being able to see them at all.  This
204    option may also be helpful if you want to see where to look on the surface
205    for new entrances.
206
207  + Highlight surveys with a white loop as the mouse is moved over them in
208    the survey tree.  This is akin to how we highlight a station with a
209    white ring, and allows restoring "double-click survey in tree to zoom"
210    which temporarily required a quadruple-click in 1.2.35.
211
212  + Only show checkboxes in the survey tree for surveys not stations.
213
214  + Fix wxWidgets assertion if the user tried to select additional surveys
215    to show via the right-click menu.
216
217  + Fix multiple survey filtering when both a parent and child survey are
218    selected.  In this case it makes most sense to show all child surveys of
219    the parent, but we actually showed a slightly arbitrary subset of the
220    child surveys of the parent.
221
222  + The checkbox area in the survey tree is now included in the area which
223    is considered by mouse-over updates such as highlighting the station or
224    survey.
225
226  + Fix display of double quotes in cavern log window (they were being replaced
227    with control character 0x16 due to a typo in the code).
228
229  + Add shortcuts to buttons in cavern log window.
230
231  + Eliminate use of gluErrorString() function which eliminates some
232    deprecation warnings when building on macOS.
233
234  + Reject multiple --survey command line options for now (only the last has
235    been used for a long time, but now we actually support multiple survey
236    filtering this matters more).
237
238* survexport:
239
240  + Report a useful error when trying to convert a .3d file without coordinate
241    system information to GPS.  Reported by Mark Shinwell.
242
243  + Handle multiple redundant --survey command line options correctly.
244
245* dump3d: Report station flag "WALL", which was added in 1.2.7.
246
247* Minor translation updates.
248
249* Update manual for Microsoft Windows changes.
250
251* tests/: Add test coverage for warnings about suspect readings
252
253* Fix warning when compiling with clang.
254
255Changes in 1.2.35 (2018-07-03):
256
257* aven:
258
259  + Viewing can now be restricted to multiple surveys.  Use the right-button
260    menu on a survey in the survey tree and select "Show" to enable checkboxes
261    for that survey and all its siblings.  Only the selected surveys are shown
262    on screen, printed and exported.
263
264  + Don't open a survey when its name is double clicked.  This was happening
265    due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
266    However, reverting that change still seems to allow double-clicking to work
267    on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
268    survey.
269
270  + Pick initial survey scaling based on whichever of the window width or
271    height gives the smaller scale.  Previously we always used the window
272    width, which can result in parts of the cave being outside the initial
273    view.  Reported by Wookey.
274
275  + Drop ability to specify a PROJ string in the export dialog.  This was added
276    to allow exporting to formats such as GPX before we added support for
277    specifying the projection in .svx files, and that support is now mature.
278
279  + DXF export now uses 2 decimal places (was 6) for the bounding box, for
280    consistency with the precision used for coordinates.
281
282  + Fix handling of surface flag during export.  In formats which discriminate,
283    legs could previously have got assigned the wrong status.
284
285  + Fix bug which probably prevented aven starting when OpenGL double buffering
286    is unavailable.  This is unlikely to affect any common configurations.
287
288  + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
289    filenames.  Issue reported by Matic.
290
291  + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
292    Probably broken since 1.2.17.
293
294* survexport: New command-line export program which uses aven's export code.
295  Replaces 3dtopos, cad3d and findentrances, since it can do all that these
296  tools could do, plus much more.
297
298* Merge more Spanish i18n updates from Evaristo Quiroga.
299
300* Minor updates to various other translations.
301
302* img library:
303
304  + Now supports reading from and writing to an existing FILE*.
305
306  + Improve API documentation.
307
308* (Microsoft Windows version): Fix packaging to include wxWidgets translation
309  files like it was supposed to, which fixes a few missing translations.  This
310  was probably broken by changes in 1.2.8.  Reported by Evaristo Quiroga.
311
312* (Microsoft Windows version): Drop two options from explorer bindings.
313  "Convert to DXF" and "Convert for hand plotting" have both been supported via
314  aven for a while, and that's a more useful way to access them as you can
315  control what gets exported.
316
317Changes in 1.2.34 (2018-03-24):
318
319* aven:
320
321  + (Microsoft Windows version): Fix error on startup in the pre-built version
322    of 1.2.33.
323
324  + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
325
326Changes in 1.2.33 (2018-03-22):
327
328* aven:
329
330  + Reliably disable scale bar in perspective view.  This is supposed to happen
331    (because the scale across the screen varies in perspective view) but
332    actually the scale bar stayed around until an update was forced for another
333    reason.  Spotted thanks to Pedro Silva Pinto.
334
335  + Make "no date"/"not in loop" colour grey.  The white was a bit bright and
336    made it harder to see the legs that had colours.  The grey now used is
337    within the brightness range of the other colours.  Fixes #94, reported by
338    Erin Lynch.
339
340  + Fix KML export - exporting both survey legs and station names resulted in a
341    malformed KML file.  This bug was introduced in 1.2.30 when support for
342    exporting passages and walls was added.  Reported by Erin Lynch in #90.
343
344  + Consistently use 2 decimal places for altitude in KML output.  Some places
345    used 8 decimal places which is appropriate for lat and long, but clearly
346    overkill for an altitude in metres and increases the file size
347    unnecessarily.
348
349  + Right-align bearing widget in print/export dialog.  The change to allow the
350    value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
351    left-aligned (due to incorrect wxWidgets documentation of the default style
352    for this control).
353
354  + (Unix version): Work around wxWidgets bug so that custom cursors work
355    under GTK3.
356
357  + (Unix version): Update GTK version reporting - report GTK3, and don't
358    bother to report subversions of GTK2 (it seems to be fairly arbitrary
359    which subversions wxWidgets defines constants for).
360
361  + Update code to work without warnings when using wxWidgets 3.1.0 (the
362    current development version).
363
364  + Make movie export code compatible with upcoming FFmpeg 3.5 release.
365    It should still work with the older versions that worked before this
366    change.  Reported by James Cowgill in https://bugs.debian.org/888334
367
368* cavern:
369
370  + Warn about 2 digit years.  We can't change the assumption that these are
371    19xx without risking breaking existing datasets, but the further we get
372    into this century, the more likely such an assumption is to catch someone
373    out.  The warning can easily be quashed by explicitly adding the assumed
374    "19".
375
376* The Spanish translation is now up to date once more, thanks to updates from
377  Evaristo Quiroga.
378
379* Merge French translation updates from Jean-Marc.
380
381* Fix transposed German Northing and Easting labels.  Fixes #95, reported by
382  milosch.
383
384* Fill in missing translations of "Easting", "Northing", "E" and "N" for
385  Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
386  translated messages.
387
388* Align .pos file headings better with columns of coordinates below for
389  Indonesian and Polish.
390
391* Fix handling of the message string "error" before messages loaded.  If
392  there's an error loading messages, we need this message to report it.
393  Reported by Martin Sluka.
394
395* Fix a few compiler warnings.
396
397* img library: Fix extracting leaf survey name for survey title.  When there
398  are three or more levels of survey, we were taking everything after the first
399  dot rather than everything after the last dot.
400
401* Fix problems with testsuite on macOS:
402
403  + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
404    - this test isn't meaningful unless the filing system is case-sensitive,
405    but happens to fail if it isn't.
406
407  + cavern.tst: Workaround limitations of Apple's sed.
408
409  + aven.tst: Fix not to hang on macOS.
410
411  + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
412
413* Clean up handling of support files in relocatable installs - this is now
414  detected at run time on macOS.
415
416* Split out macOS Aven.app creation into a make rule so it can be easily used
417  by the homebrew formula.
418
419* buildmacosx.sh:
420
421  + Fix when WX_CONFIG not specified - this was giving a confusing error like:
422    ./buildmacosx.sh: line 163: --cc: command not found
423
424  + Use wxWidgets 3.0.4.
425
426* Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
427  and we currently require 2.8 or newer.
428
429Changes in 1.2.32 (2017-07-08):
430
431* aven:
432
433  + Make splays on printouts a darker shade of grey.  Reported by Erin Lynch
434    and Anthony Day.
435
436  + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
437    POS), the value in the Z dimension was negated.  Bug introduced by fixes
438    for export of rotated plans and tilted elevations in 1.2.27.  Reported by
439    Erin Lynch in #89.
440
441  + Ignore viewing angles for export formats which work in 3D.  When the
442    rotation and tilt controls are hidden in the export dialog we were still
443    using their values to transform the data, so if you set them with for one
444    export format which support them, then switched to an export format which
445    doesn't, you'd get bogus coordinates in the exported file.  Bug probably
446    introduced in 1.2.27 by fixes for exports of rotated plans and tilted
447    elevations.
448
449  + Fix exporting to skencil and Survex .pos formats.  When aven's export to
450    .pos was added in 1.2.19, the ordering didn't match up and since then .pos
451    export has produced skencil files and vice versa.
452
453  + Don't leave terrain on if loading terrain data fails.  Previously if you
454    clicked the terrain icon (or via the menu) with no terrain loaded, but no
455    terrain got loaded (e.g. because the survey data lacks an explicit
456    coordinate system, or because the file failed to load, or because you
457    cancelled the dialog) then the terrain icon/menu item was still changed to
458    "on".
459
460  + Disable texturing while drawing terrain.  Previously the terrain got a bit
461    darker when "Textured Walls" were enabled.
462
463  + Force a refresh when "Textured Walls" are enabled or disabled.  Previously
464    the display wouldn't update right away.
465
466* Manual:
467
468  + Document how to specify fixed point altitude in feet.
469
470  + Explain why *fix warns about unused fixed points
471
472* Building from source now requires a compiler with decent support for C++11.
473  If you're using GCC, then GCC 4.7 should suffice.  This should not be an
474  onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
475  enough GCC.  If special options are needed, these should get probed for and
476  automatically.  Fixes building 1.2.31 with GCC < 6, reported by Wookey.
477
478Changes in 1.2.31 (2017-07-01):
479
480* aven:
481
482  + Use superscript 'g' symbol instead of word 'grads' in status bar.  This
483    conserves the limited space available, and we already do this in the
484    compass and clino indicators so it's more consistent too.
485
486  + Show one decimal place on measure line bearing.  Pointed out by Benedikt
487    Hallinger on the therion list, though I'm sure this has been asked for
488    before by others.
489
490  + Show gradient of the measuring line when both ends are stations.
491
492  + Allow selection of text in cavern log window.  Selection was disabled in
493    1.2.28 because it seemed you couldn't actually copy selected text to the
494    clipboard, but retesting this now actually works fine for me, both with
495    current git master with the change reverted, and with code just before the
496    original change.
497
498  + More robust parsing of cavern output (cleanly handle context highlighting
499    which extends beyond the end of the line).
500
501  + Allow showing duplicate legs as dashed lines or hiding them entirely,
502    with dashed now being the default.  Implemented by Patrick Warren.
503
504  + Also allow "Dashed" for splays and "Faded" for duplicate legs.
505
506  + Splay legs in surface data are also shown faded.
507
508  + Check environment variables VISUAL and EDITOR when looking for editor to
509    use when a warning or error is clicked on in the cavern log window.  The
510    specified editor may have a GUI or need to run in a terminal, so we have to
511    special-case each editor supported, and that means we can pass extra
512    options needed to position the cursor on the appropriate line/column.
513    Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
514    emacs, nano, jed, kate.  Suggested by Wookey.
515
516  + Fix handling of non-square terrain data files - the X and Y dimensions were
517    swapped.  Reported by detrito.
518
519  + Improve parsing of DEM data with .hdr file.  Use documented defaults for
520    more values, and where we only support a subset of values (or a particular
521    value) check for unsupported values in more cases.
522
523  + When colouring by depth, fix colouring and texturing of polygons which
524    cross depth bands.  The previous problems were most obvious with high
525    chambers and long legs down deep pitches, especially in for surveys without
526    much vertical range.
527
528  + Support for drawing blobs using point sprites was added in 1.2.28,
529    but caching that this worked wasn't hooked up properly so the test to
530    see if this worked would happen at the start of each run.  This is now
531    cached as intended which should reduce start up time a little when blobs
532    are drawn in this way.
533
534  + Fix drawing of crosses with lines.  This is a fall-back case which is
535    rarely used as most OpenGL setups will handle a better method, but it was
536    resulting in crosses with a four-pixel square in the centre - now the
537    centre should be a single pixel.
538
539* cavern:
540
541  + Allow *data with no arguments to reset the current style - useful for
542    entering passage data where there are side passages.
543
544  + Fix hang processing file without newline at end.  This bug was introduced
545    by changes in 1.2.28.  Reported by Mark Brown.
546
547  + (Mac OS X and Microsoft Windows versions): Build with newer version of
548    PROJ library which fixes buggy handling of *fix with lat-long coordinates.
549    Also add a testcase to the testsuite to alert users building for themselves
550    with an affected PROJ version on any platform.  Reported by Ross Davidson.
551
552  + Fix cavern to handle Compass .DAT with no survey team.  Previously this
553    resulted in the bogus error: Expecting numeric field, found "FROM"
554    Reported by Erin Lynch.
555
556  + Handle UTF-8 "BOM" at start of .svx files.  Unicode doesn't recommend its
557    use, but Microsoft stuff seems to like to create files with it in, and the
558    error cavern currently reports for such files is very confusing, so it
559    seems best to just handle it.  Reported by Rob Eavis.
560
561  + Change a couple of messages to use double quotes for consistency with all
562    other messages.
563
564* extend:
565
566  + Now runs a bit faster.
567
568  + Splays are now carried over the extended survey.  The current handling
569    is simplistic, but should do a good enough job to be more useful than
570    discarding splays.  The splays at each station are all rotated together
571    based on the bearing between the stations either side of the current one
572    along the first path extended through that station.  This nicely handles
573    dead ends and the situation at the top or bottom of a pitch, and should
574    tend to pick an angle close to the passage orientation along a traverse.
575    It's weakest at junctions.  Feedback (especially examples which could
576    be handled better) most welcome.
577
578* French translation is now up to date again, thanks to Jean-Marc.
579
580* Remove erroneous menu shortcut markers from Polish translations.
581
582* Fill in some missing translations in several languages by using message
583  translations from therion.
584
585* Add note to *fix documentation to clarify the coordinate order with *cs
586  long-lat.  Issue raised by Ross Davidson.
587
588* Fix errors in documentation of *units: "DEG" should be "DEGS", and
589  "MINUTES" has been supported for ages but wasn't documented.  Reported by
590  Footleg.
591
592* Fix a few typos in the documentation.
593
594* Fix compilation warning with recent GCC.
595
596Changes in 1.2.30 (2016-10-03):
597
598* aven:
599
600  + (Microsoft Windows version): Fix crash when trying to print or export
601    (probably introduced in 1.2.28).  Reported by Brian Clipstone.
602
603  + Report error if terrain file contains no terrain data in area of survey.
604    Suggested by detrito.
605
606  + Errors when writing an export file were reported with the wrong filename
607    - the .3d file, not the filename we were trying to write to.
608
609  + Export to KML now supports exporting passages, walls and cross-sections.
610    Addresses the remainder of ticket #4.
611
612* Add man page for dump3d.
613
614Changes in 1.2.29 (2016-09-27):
615
616* aven:
617
618  + Fix SVG output with non-ASCII characters (the charset in the SVG file
619    is now set to UTF-8 not ISO-8859-1).
620
621  + (Microsoft Windows version): Fix error dialog on startup in pre-built
622    version.  Reported by Brian Clipstone.
623
624* Manual: Add link to TerrainData wiki page.  Omission highlighted by Erin
625  Lynch and "detrito".
626
627* Fix to build without FFmpeg/libav and with older versions, broken by changes
628  in 1.2.28.  Reported by James Begley.
629
630Changes in 1.2.28 (2016-09-24):
631
632* cavern:
633
634  + Show the contents of the line after error and warning messages while
635    processing survey data, and indicate the region of the line in many cases
636    in the same style that compilers such as GCC and clang use (using the
637    column number we already have, plus new width information).  Based on a
638    patch from Mateusz Golicz.
639
640  + Add column and width information for many more error and warning messages.
641
642  + Fix column for "Separator in survey name" warning.
643
644  + Improve warnings when using a backclino with range 0-180 degrees (reusing
645    the same machinery we already have for a forward clino with range 0-180
646    degrees).
647
648* aven:
649
650  + Include LRUD in printout/export of extended elevations, broken by
651    improvements to export of tilted elevations in 1.2.27.  Reported by Anthony
652    Day.
653
654  + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
655    usefully.  Reported by Anthony Day.
656
657  + Remember scale from previous print or export operation in the same run of
658    aven.  Suggested by Stuart Bennett.
659
660  + Convert range indication below shown line to a highlight on that region
661    of the line in cavern log window.
662
663  + Fix colouring of error/warning without column in cavern log window.
664
665  + Fix click on error/warning without column in cavern log window.
666
667  + Fix highlight of translations of "error" or "warning" containing non-ASCII
668    characters.  This fix for this only works with a Unicode build of
669    wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
670    shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
671    Reported by Mateusz Golicz.
672
673  + Disable selection of text in cavern log window - you can't currently copy
674    it to the clipboard, so until that's implemented it seems better to disable
675    the ability to select it.  Reported by Wookey.
676
677  + Avoid special "1000" scale entry when exporting.
678
679  + Show 1 page when "One Page" selected.
680
681  + Reload processed data when restricting view.  Fixes failure when
682    restricting view on data just processed via aven.  Spotted by Andrew
683    Atkinson and myself.
684
685  + Don't hide blobs and crosses behind terrain.  Reported by Jenny Black.
686
687  + Fix rendering of crosses using point sprites.  The texture being used was
688    misaligned relative to the image used for the visual fidelity check, so the
689    check always failed and point sprites would never be used.  Where point
690    sprites are supported, they're probably the fastest option - on my netbook
691    this change improves FPS by ~6 fold when displaying crosses for a large
692    survey.
693
694  + Support drawing blobs using point sprites.  About 5 times faster than using
695    lines on my netbook.
696
697  + Recheck how best to draw crosses and blobs on the first run after Survex
698    is upgraded (or downgraded) as the rendering code may have changed (we
699    already recheck when the OpenGL hardware or driver changes).
700
701  + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
702    MPEG4 produces smaller output of higher quality, and should be widely
703    supported these days.  And I can't get the MPEG1 output to work without
704    buffer underflows, resulting in a file which doesn't play without
705    glitches.
706
707  + Add OGG video to the list of formats - it's more compact than the others
708    we currently list, though slower to write.
709
710  + Fix export to movie formats for which libav/FFmpeg needs to seek the file
711    being written.  This was broken by changes in 1.2.27.
712
713  + Overhaul movie export for the current FFmpeg API, fixing deprecation
714    warnings when building against a recent version.
715
716  + (Microsoft Windows version): Fix corrupted exported movie files.  1.2.27
717    changed the movie export code to allow writing to files with non-ASCII
718    characters in the names, but the new code failed to open the file in binary
719    mode, leading to corrupt output.  Fixes #81, reported by Erin Lynch.
720
721  * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
722    movie export.
723
724  * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
725    export.
726
727* Fix to build without FFmpeg/libav, broken by changes in 1.2.27.  Reported by
728  James Begley.
729
730* The Polish translation is now very close to being complete, thanks to a
731  substantial update from Mateusz Golicz.
732
733* Merge catalan translation updates from Adolfo Jayme.
734
735* (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
736  messages get used automatically.
737
738* cavern.tst: Remove random : from after ] - dash ignores the extra character,
739  but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
740
741* cavern.tst: Add expected output for more testcases.
742
743* Remove unwanted execute bit from some testcase data.
744
745* Use https for more URLs which support it.
746
747Changes in 1.2.27 (2016-06-06):
748
749* aven:
750
751  + Right click on a survey in the survey tree now gives a pop-up menu
752    with "Hide others", which restricts the view to just that survey
753    and any subsurveys.  Right click on the root of the survey tree
754    gives a menu with "Show all" to undo any restriction in effect.
755    (Currently these are implemented by reloading the file and using
756    the same machinery as the --survey= command line option, but that will
757    probably change in the future).
758
759  + If there's a sub-survey restriction (from the --survey= command line
760    option or the new UI described above) it is now shown in brackets after
761    the survey tree root.
762
763  + When reloading a survey, preserve the current view position (previously
764    the view was recentred).
765
766  + When reloading a survey, actually preserve the current scale factor
767    (this was meant to happen, but the adjustment was applied in the
768    wrong direction).
769
770  + New "File->Extended Elevation..." menu item provides a way to generate
771    extended elevations for simple cases without having to use the command
772    line.  Suggested by Fleur Loveridge.
773
774  + Don't process key presses if accompanied by an unexpected modifier key.
775    In particular, this means that aven no longer interferes with Alt+<function
776    key> (which is typically handled by the desktop) and Alt+<letter> (which is
777    typically a menu short cut).  Reported by Владимир Георгиев.
778
779  + Reduce file loading time by ~5%.  The station name compare function was
780    something of a hot spot, and optimising it yielded a nice improvement.
781
782  + Allow splay legs to be disabled in when printing and exporting.  Mostly
783    addresses #60.
784
785  + SVG export now shows splay legs thinner and in grey.  See #60.
786
787  + Fix export of rotated plans and tilted elevations - previously plans were
788    always aligned with North up, and elevations which weren't exactly side on
789    were exported as plans.  Reported by Stuart Bennett.
790
791  + Fix offset bounding box for exported elevations.
792
793  + In print/export dialog the bearing value now wraps if you scroll up past
794    360 or down past 0.
795
796  + Fix greying out of LRUD-based controls in the print/export dialog when the
797    view is tilted (i.e. not plan or elevation).  This stopped working in
798    1.2.18 when the pan and tilt spin controls were changed from integer- to
799    real-valued ones.
800
801  + Printouts now show LRUD as pale grey arrows from the station they are
802    measured from.  Based on patch from Michael Sargent.  Closes #65.
803
804  + Take LRUD into account for printout size.  Fixes #72, reported by Erin
805    Lynch.
806
807  + Update movie export code to work with latest version of FFmpeg.
808
809  + Make "Show Log" a toggle, so you can click on the button to take a look at
810    the log, and a second click returns you to the survey view.
811
812  + (Microsoft Windows version): Open the font file in binary mode - it looks
813    like we were lucky and the font file (or at least its current version)
814    would have loaded OK in text mode despite being binary data.
815
816  + (Microsoft Windows version): Exporting to files with non-ASCII filenames
817    should now work.
818
819* cavern:
820
821  + Allow tape or backtape to be omitted.  Reported by Erin Lynch.
822
823  + Grid convergence is now corrected for when using automatically
824    calculated declinations (*declination auto <X> <Y> <Z>).  Requested
825    by Mateusz Golicz on the mailing list.
826
827  + Clear any cached calculated declination upon another *declination auto
828    with different coordinates.  Previously if the date stayed the same,
829    a previously cached declination for the old coordinates was used.
830
831  + Fix check for end of version number array in *required.   We would check up
832    to 12 version components, the last 9 being bogus.  In practice, *require is
833    only likely to be used with up to three components, so this wouldn't be an
834    issue.
835
836  + *begin with an invalid prefix could cause a crash in some cases.  Fixed
837    by patch from Colin Watson.
838
839  + Report column locations for errors to do with readings.
840
841* Merge translation updates from Jean-Marc.
842
843* img library: Better document which members can be set when writing.
844  Highlighted by email query about use of img API from Владимир Георгиев.
845
846* Document how *declination interacts with *calibrate declination if both are
847  used in the same dataset.
848
849* doc/3dformat.htm: Update details of how changes to the current label buffer
850  are encoded to reflect changes in v8.  Reported by Angus Sawyer.
851
852* Use docbook2man instead of docbook-to-man to generated Unix man pages
853  from SGML source.  The latter seems to be no longer actively maintained, and
854  docbook2man now does a similarly good job.
855
856* Use https for survex.com links, and for other sites which support it.
857
858Changes in 1.2.26 (2016-01-07):
859
860* aven:
861
862  + (Microsoft Windows version): Fix to be able to process .svx files with
863    cavern again.
864
865* (Microsoft Windows version): Simplify upgrading process with innosetup
866  installer - if Survex is already installed, we now just install to the same
867  location and use the same start menu folder.
868
869* (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
870  Fixes #79, reported by James Begley.
871
872* (Linux version): survex.spec: Fix to work with RPM 4.13.  Fixes #79, reported
873  by James Begley.
874
875Changes in 1.2.25 (2016-01-05):
876
877* aven:
878
879  + Drop broken code which attempts to fix 2D pitches.  Fixes #73, reported by
880    Erin Lynch.  #76 tracks the issue the removed code was trying (but failing)
881    to address.
882
883  + When animating, don't try to update station info based on mouse movement
884    over the survey tree.
885
886  + Further improve code to handle cavern subprocess in aven.
887
888  + Fix jump to error for filenames containing colons when the error location
889    doesn't have a column number.  Bug noted by Jenny Black.
890
891  + If we encounter bad UTF-8 in cavern output, replace it with a red and white
892    ? in a diamond (previously we gave up showing output at the first bad
893    sequence).  This can happen if you process a .svx file which isn't UTF-8
894    encoded.
895
896  + (Unix version): Don't try to set the terminal window title when opening an
897    editor from the cavern log window - gnome-terminal no longer supports this,
898    and there doesn't seem to be a portable option for specifying the title for
899    terminals which do still support this.
900
901  + (Microsoft Windows version): Also quote for cmd.exe so that paths with
902    spaces in work reliably.  Reported by Marco Cotto.
903
904* cavern:
905
906  + Improve error for mismatched fore/back-sight plumbs, reported by Andy
907    Edwards (see #78).
908
909  + Fix to use correct sd for backcompass.  We were using zero instead, the
910    most obvious effect of which was that the threshold for warning about
911    differing COMPASS and BACKCOMPASS was about 71% of what it should have
912    been, so we were warning in more cases than we should have been.
913
914  + Implement support for specifying a length on backsights - if you're using
915    something like a disto-x, you'll get a distance reading for the backsight
916    too.  Fixes #71, reported by Erin Lynch.
917
918  + Make line counting more robust to mixed line ends.  Noticed in example file
919    from Pete Smart (see #69).
920
921* extend: New --show-breaks option which adds a leg flagged as surface survey
922  between each points at which a loop has been broken.  Suggested by Jenny
923  Black.
924
925* (Unix version): Update filetype metadata to work with modern desktops.
926
927* Fix incorrect reporting of errors reading and writing processed survey data.
928  Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
929  IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
930  external programs using the img library, only Survex).  Reported by Jenny
931  Black.
932
933* Add missing options to extend man page and --help output.  Noted by Jenny
934  Black.
935
936* Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
937
938* Fix broken SGML markup in manual.
939
940* Fix typo in manual reported by Jenny Black.
941
942* Update vim syntax file for newer commands, etc.
943
944* Minor translation updates.  Thanks to Piotr Strębski and Jean-Marc.
945
946* Fix to compile with FFmpeg 2.9.  Reported by Andreas Cadhalpun in
947  https://bugs.debian.org/803863
948
949* Stop maintaining ChangeLog files.  They make merging patches harder, and stop
950  'git cherry-pick' from working as it should.  The git repo history should be
951  sufficient for complying with GPLv2 2(a).
952
953* (Microsoft Windows version): The installer requires admin privileges on Vista
954  and later and OS versions older than Vista are past end of life, so drop code
955  which tries to set up the registry differently depending if we have admin
956  privileges or not.
957
958Changes in 1.2.24 (2015-09-23):
959
960* aven:
961
962  + (Microsoft Windows version): Fix the cavern log window.  Reported by Brian
963    Clipstone.
964
965  + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
966    Reported by Jenny Black.
967
968  + If wx was built with thread support, aven now runs cavern from a separate
969    thread, which works much better under wxMSW (where we can't use select),
970    and also seems a bit smoother on Linux.
971
972  + Fix handling of encoding of filenames when the operating system has no
973    locale installed corresponding to the language selected for Survex's
974    messages.
975
976  + Undo accidentally committed debugging code which was sending message to
977    the terminal in 1.2.23.
978
979* (Linux version): configure now looks first for wx-config-3.0, which Fedora's
980  wx3 packages have.  Reported by James Begley.
981
982* Indonesian translation fully up to date again.
983
984* Manual: Document anonymous stations, based on the text from NEWS.  Reported
985  by Wookey.
986
987Changes in 1.2.23 (2015-09-06):
988
989* aven:
990
991  + Updating the cavern log window is now much smoother, especially on slower
992    machines.
993
994  + Show "busy" mouse cursor while processing survey data.
995
996  + Fix an assertion if you try to start processing a survex file while one is
997    already being processed.
998
999  + Processing a .svx file with an error now still adds it to the file history.
1000    Reported by Martin Green.
1001
1002  + Fix the orientation of the starting end of tubes.
1003
1004* cavern:
1005
1006  + New *ref command to allow specifying an external reference (e.g. where to
1007    find the original survey notes).
1008
1009  + Drop support for showing percentage progress in cavern.  It's confusing in
1010    a multiple-file dataset as it shows progress in the current file so jumps
1011    around.  It also slows down processing, and on a slow machine you'd don't
1012    want that, while on a fast machine processing isn't slow enough for the
1013    progress display to be useful.
1014
1015* French translation is now completely up to date, thanks to Michel Bovey.
1016
1017* Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
1018  OS X so that things like "*cs EPSG:29903" work.  Reported by Graham Mullan.
1019
1020* (Microsoft Windows version): Process survey data with aven rather than
1021  running cavern.
1022
1023* (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
1024  releases have been built with 5.5.3) to see if that solves Ray Duffy's
1025  reported issue with not having file associations for .svx files created.
1026
1027Changes in 1.2.22 (2015-08-17):
1028
1029* aven:
1030
1031  + Ensure that the window has a depth buffer.  Whether it does by default
1032    seems to vary depending on OS and maybe graphics card.  Fixes #55 (terrain
1033    is no longer visible through itself), and also the rendering of passage
1034    tubes.  Thanks to Martin Green for pointing me in the right direction for
1035    finding this fix.
1036
1037* cavern:
1038
1039  + Fix *declination with an angle to actually work.
1040
1041  + Fix assertion if we try to identify a hanging survey by an anonymous
1042    station.
1043
1044  + Improve errors for invalid survey names in *begin, *end, *equate and
1045    *export.
1046
1047Changes in 1.2.21 (2015-07-28):
1048
1049* aven:
1050
1051  + Fix exporting to KML and other text-based formats to always use "." for the
1052    decimal separator - previously "," would be used when the user's locale
1053    specified this for the decimal separator.  Reported by Jan Schorn.
1054
1055  + Implement exporting of survey legs in KML format.
1056
1057  + Put "paddle" placemarker icons on stations in exported KML files, using the
1058    same colour coding for entrances, fixed points and exported points as aven
1059    does.
1060
1061  + Remove the "Coordinate projection" field from the print dialog, as it isn't
1062    relevant there.  Reported by Wookey.
1063
1064  + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1065    been too small).  Reported by Wookey.
1066
1067  + Don't rescale if the same file is reloaded, but adjust the volume diameter
1068    as appropriate.
1069
1070  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1071    values on Windows.
1072
1073* cavern:
1074
1075  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1076    radians, but we were passing degrees, which would generally cause the
1077    conversion to the output coordinate system to fail.  Reported by Wookey.
1078
1079  + Fix *fix with standard deviations when *cs is in use, give an error for use
1080    of *fix with standard deviations before *cs.
1081
1082  + Add new *declination command with support for setting the declination
1083    automatically from the IGRF model based on the survey date.  Thanks to the
1084    Therion developers for the IGRF support code, which we're reusing.
1085    Fixes #54, reported by Wookey.
1086
1087  + Allow the units for the zero error to be specified, making it easier to
1088    specify calibration with a scale if you measure the zero error externally
1089    (rather than using the instrument itself).  Fixes #61, reported by Andrew
1090    Atkinson.
1091
1092  + Report the error from PROJ when coordinate conversion fails as part of the
1093    actual error rather than on a separate line.
1094
1095  + Fix use after free after *solve.  This only occurs if a leg between the two
1096    exact same stations appears right before and right after the *solve, which
1097    is unlikely in real data, but the testsuite has an instance of this.  This
1098    was introduced by the repeat leg averaging added in 1.2.17.
1099
1100  + Fix small memory leak when solving network.  This doesn't really matter
1101    when solving at the end of processing as cavern will exit after that, but
1102    if *solve is used we continue processing after solving.
1103
1104* Remove compatibility handling for specifying a country variant of a language
1105  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1106  changed to the standard "en_US" way back in 2001.  This code was mangling
1107  character sets with a "-" in, and is no longer useful.
1108
1109* Ignore any "@<something>" modifier in the language code.
1110
1111* Improve documentation of magnetic declination handling, and cover the new
1112  "*DECLINATION" command.
1113
1114* Document aven's command line options in the manual and its man page.
1115  Reported by Jenny Black.
1116
1117* Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1118  documentation.
1119
1120* Remove references to SpeleoGen from the documentation - it hasn't been
1121  updated for many years, and can't read recent versions of the .3d format.
1122
1123* Strip documentation references to obsolete versions of MS Windows.
1124
1125* doc/HACKING.htm: Update list of debian packages to install to build from git.
1126
1127Changes in 1.2.20 (2015-06-26):
1128
1129* aven:
1130
1131  + When printing, use the top margin rather than the right margin to calculate
1132    the height of the printable area.  In practice, the two values seem to be
1133    the same or very similar by default.
1134
1135  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
1136    Maynard.
1137
1138  + Optimise the size of the about dialog images.
1139
1140  + Add support for reading terrain data which isn't in a .zip file.
1141
1142  + Force a refresh after loading terrain data so that it gets displayed right
1143    away.
1144
1145  + Make checks for terrain data extensions in zip files case insensitive.
1146
1147  + If reading terrain data fails, always report an error and never try to
1148    display it.
1149
1150* cavern: Allow clino readings in diving style data, suggested by Andrew
1151  Atkinson.  Currently these readings are ignored, but a future version will
1152  check that they're consistent with the angle given by the depth gauge and
1153  tape, and perform suitable averaging.
1154
1155* Remove lingering traces of svxedit.
1156
1157* configure: Fix to allow compiling without libav/ffmpeg, as was possible
1158  before 1.2.19.
1159
1160* (Unix version): Install the filetype and aven application icons under
1161  /usr/share/icons/hicolor, which is where they're expected to be these days.
1162
1163* (Unix version): Add %f to Exec in survex-aven.desktop.
1164
1165* (Mac OS X version): Remove useless extra copy of about box images from OS X
1166  disk image.
1167
1168* (Mac OS X version): Only ship one copy of each of the translations.
1169
1170* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1171  libav features we don't use.
1172
1173* (Microsoft Windows version): Reduce the size of the aven binary by disabling
1174  a load of libav features we don't use.
1175
1176* (Microsoft Windows version): Update message files to fix a missing Chinese
1177  message in the installer.
1178
1179Changes in 1.2.19 (2015-06-18):
1180
1181* aven:
1182
1183  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1184    the exported file in 1.2.18.
1185
1186  + Add exporting to Survex .pos format.
1187
1188  + If the measuring line isn't currently active, pressing "Escape" will now
1189    exit full screen mode.
1190
1191  + (Mac OS X version): Change the shortcut for full screen mode to be the
1192    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1193    using since 1.2.7).
1194
1195  + (Mac OS X version): When we centre the view on the station this can
1196    generate a mouse move event, so clear the variable which says we are
1197    dragging before we process a left click on a station.  This avoids random
1198    rotations of the survey when clicking on a station, reported in #47 by Hugh
1199    St. Lawrence.
1200
1201  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1202    icons from being rescaled and looking fuzzy.
1203
1204  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1205    toolbar icons from being rescaled, but which requires an unreleased version
1206    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1207
1208  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1209    the top of the screen, since we can't seem to display the menu bar in this
1210    case like we do on other platforms.
1211
1212  + (Mac OS X version): Enable aven's movie export feature.
1213
1214  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1215    support multi-monitor setups.
1216
1217  + (Mac OS X version): Silence warning visible when aven is run from a
1218    terminal about a missing CFBundleTypeRole.
1219
1220  + When reading terrain data from a .zip file, report an error if the .zip
1221    file is bad, or if it doesn't contain any terrain data we recognise.
1222
1223  + Tweak error message in terrain reading code to distinguish two failure
1224    cases.
1225
1226  + Add viewing angles and scale to footer, and shorten some of the other items
1227    to make room for this extra information.  (Fixes ticket #52, reported by
1228    Erin Lynch)
1229
1230  + If the footer is wider than the printout width, scale down the font used
1231    so that it exactly fits; if the footer is narrower, than space out the
1232    items in in so it uses the full width.
1233
1234  + If the saved size for aven's window exceeds the current display size
1235    (mostly likely because we're now plugged into a smaller monitor), then
1236    reduce the size of the window to fit the display.  If the saved size is <
1237    (480x320), increase it to at least that, as aven isn't usable in a smaller
1238    window.
1239
1240  + Remove crude bodge which tries to pick a nicer initial window size when
1241    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1242    with the same size window it had when it was closed, so the initial size is
1243    only relevant on the first ever run.
1244
1245* Assorted translation updates.  Notably Indonesian is at 100% again.
1246
1247* Stop trying to catch and report signals.  The only real reason to do it is so
1248  we can say "Bug in program detected! Please report this to the authors"
1249  before we exit, but when the program crashes that's pretty obvious.  In aven
1250  we try to pop up a message box for this message, which may fail due to
1251  whatever caused the signal, while with the command line tools there's no
1252  great benefit over just letting the shell report the signal.
1253
1254* Use pkg-config to probe for libav and proj, which sorts out the correct flags
1255  for building on OS X against a static install of libav.
1256
1257Changes in 1.2.18 (2015-06-03):
1258
1259* aven:
1260
1261  + Add support for reading terrain data (from a zip file containing either an
1262    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1263    rendering it as a transparent surface.
1264
1265  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1266    sanely want to perform from the menu.
1267
1268  + Create a "Colour by" submenu of the "View" menu to house the various
1269    colouring options.
1270
1271  + Add "Colour by Gradient" and "Colour by Length".
1272
1273  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1274    which seems more logical, and also allows the dialog to be closed by
1275    pressing "Escape".
1276
1277  + Destroy any existing clipping region before we write the page footer.
1278    Hopefully solves ticket #52, reported by Erin Lynch.
1279
1280  + Don't round bearing and tilt angles to integers when printing and
1281    exporting.
1282
1283  + Add passage export for EPS format.  (Partly addresses ticket #4)
1284
1285  + Add JSON export.  This should be regarded as experimental, and the format
1286    is quite likely to change.
1287
1288  + Pressing F6 now toggles the display of rendering stats, currently FPS
1289    (Frames Per Second) and the number of triangles in the terrain mesh.
1290
1291  + Add a menu item and toolbar button to show the cavern log window if the
1292    currently shown survey data was processed by aven.  Reported by Hugh St
1293    Lawrence in #47, and by Dave Clucas and others previously on the list.
1294
1295  + Add "Save Log" button to Aven's cavern log window.
1296
1297  + In cavern log window, highlight "error" markers in red and "warning"
1298    markers in orange.
1299
1300  + Rework code to read cavern's output.  In particular, we no longer mix
1301    buffered and non-buffered system calls.
1302
1303  + Aven's support for reading colours and font sizes for printouts from
1304    print.ini has never worked - the contents of the ini files are ignored due
1305    to a bug which has been there since the code was added in 2005 - but nobody
1306    has ever complained.  So just strip out that code entirely - we should
1307    support setting the colours and font sizes, but a GUI interface for setting
1308    them would be better.
1309
1310  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
1311    Gee.
1312
1313  + Take the width of the messages used above the compass and clino into
1314    account when calculating how much space to allow for them - now the labels
1315    won't overlap or be cut off in translations where they are long.
1316
1317  + (Mac OS X version): Attempt to address the size of the toolbar icons.
1318
1319* cavern:
1320
1321  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
1322    susscorfa).
1323
1324  + Use the currently set units when outputting measurements in warnings,
1325    errors, and the stats at the end of the run.  Requested by Bill Gee.
1326
1327  + Include column number when a *include file isn't found.
1328
1329  + Show 'error' in front of error messages, like we show 'warning' in front of
1330    warnings.  Fixes #48, reported by Wookey.
1331
1332  + Increase the threshold for warning that fore and back measurements differ
1333    from 2 SDs to 3 SDs.
1334
1335* findentrances: If the 3d file specifies the coordinate system, use it.
1336
1337* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1338  would be nice to have, svxedit doesn't really offer that, and it looks ugly
1339  in a modern desktop.
1340
1341* If we run out of memory while reading a processed survey data file, include
1342  the filename in the error message.
1343
1344* Many translation updates - notably Indonesian and Russian are now the two
1345  most complete translations.
1346
1347* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
1348
1349* Transliterate gradient and infinity symbols if the current character set
1350  lacks them.
1351
1352* Add SVG version of .plt icon.
1353
1354* Manual:
1355
1356  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
1357    highlighting that the previous list was incomplete.
1358
1359  + Document averaging of a group of repeated readings.
1360
1361  + Add a link to the sample data from the manual.
1362
1363  + Remove references to contact addresses which are no longer there.  Remove
1364    offer to post people floppies, and references to a CD image which isn't
1365    available for download.
1366
1367* Remove non-breaking spaces from the diffpos and extend manual pages, as they
1368  actually make the output formatting worse (presumably these used to work
1369  around a since-fixed bug in one of the docbook processing tools).
1370
1371* doc/TODO.htm: Update.
1372
1373* Fix to compile without warnings with 'g++ --std=gnu++11'.
1374
1375Changes in 1.2.17 (2015-02-24):
1376
1377* MacOS X version:
1378
1379  + Update INSTALL file with current status.
1380
1381  + Aven.app now has a custom icon.
1382
1383  + Add icons for all the filetypes supported.
1384
1385  + Add Finder actions for .svx, .3d, .plt and .pos files.
1386
1387  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1388    currently do this for us.
1389
1390  + aven: Fix short-cut for toggling Full Screen mode.
1391
1392  + aven: Make "About" menu item appear.
1393
1394  + aven: Fix "Close" button in about dialog.
1395
1396  + aven: Make custom cursors black with a white outline to match the standard
1397    OS X cursor.
1398
1399  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
1400    still doesn't really work like a standard app though - e.g. you can't load
1401    files from Finder (instead run svxedit.app and use File->Open), the font
1402    size of most menu items is wrong, the icon for the app is the wish icon
1403    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1404    probably more.  I'd probably recommend using another editor (OS X comes
1405    with TextEdit.app for example).
1406
1407  + The documentation is now in a "Docs" directory alongside the apps, rather
1408    than in the rather less obvious "share/doc/survex" directory.
1409
1410  + Default to building for x86_64, since all modern Macs are 64 bit.
1411
1412  + Disable use of liblzma when building wxWidgets for OS X, which was
1413    preventing the build from working on OS X 10.6.8.
1414
1415  + Download wx sources from SF via redirecting link.  Thanks to David A.
1416    Riggs.
1417
1418  + buildmacosx.sh: Handle the mount point for the disk image containing a
1419    space.
1420
1421  + Link with a static build of PROJ for doing coordinate system conversions.
1422
1423  + Build wx with --disable-webview to avoid a compilation failure on OS X
1424    10.10.1.
1425
1426  + Use wx-config --cc and --cxx to get the compilers to use for building
1427    everything else, as wx adds options to them which otherwise cause linking
1428    errors.
1429
1430  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
1431    smaller download.  This means OS X 10.4 is required, but we probably
1432    already need at least 10.5 because that's the minimum version which the
1433    wxWidgets build supports by default.
1434
1435  + Remove unused files and copies of files from the diskimage.
1436
1437* cavern: If the same leg is repeated consecutively, average the readings and
1438  treat as a single leg.
1439
1440* dump3d: Report SEPARATOR used by the file being read.
1441
1442* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
1443
1444* aven:
1445
1446  + Greatly reduce flicker when mouse is moved to the top of the screen in full
1447    screen mode and the menu bar reappears.
1448
1449  + For export formats where scaling is supporting, aven now actually uses the
1450    scale specified in the export dialog (previously it ignored this and used
1451    1:500).
1452
1453  + Reimplement animation so that it's based on angular change per unit of
1454    elapsed time, rather than averaging the time take for the last two scene
1455    redraws.  This gives smoother animation in the face of variable load and
1456    scene redraw time, and should be more consistent between platforms.
1457
1458  + Switching to a point of the compass during auto-rotation now jumps straight
1459    there rather than the two animations fighting.
1460
1461  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
1462    fast.
1463
1464  + Disable stepping the rotation angle when animating (previously we only did
1465    when rotating).
1466
1467  + Speed up start-up a bit - rather than loading icons from individual PNG
1468    files on disk, compile them into the aven binary.
1469
1470* (Unix version): Add "MimeType" field to desktop files so that file
1471  associations work out of the box with modern desktop environments.
1472
1473* Add start of Hungarian translation from Imre Balogh.
1474
1475* Merge in many updates to the Russian translation from "vsuhachev".
1476
1477* Assorted minor updates to other translations.
1478
1479* Create scalable (SVG) versions of file type icons.
1480
1481* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
1482  we're using git.
1483
1484* tests/: Improve test coverage in a few places:
1485
1486  + Extend tests of fore and back sights to test calibration of the back
1487    compass.
1488
1489  + Test "Can't calibrate angular and length quantities together" error.
1490
1491  + Check that "*set names ." works when "." is also the decimal point.
1492
1493Changes in 1.2.16 (2014-10-17):
1494
1495* aven: Add KML export (stations only currently).
1496
1497* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
1498
1499* aven: Fix corrupted names in exported files.
1500
1501* aven: Fix error log window under wxWidgets >= 2.9 to include the system
1502  information before the first log message like it does under wxWidgets 2.8.
1503
1504* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
1505
1506* tests/: Improve test coverage.
1507
1508* Translation updates for many languages, plus the start of translations to
1509  Greek and Polish.
1510
1511* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
1512  by Martin Sluka.
1513
1514* Fix warnings when compiling with clang (which is the default compiler on
1515  Mac OS X).  Reported by Martin Sluka.
1516
1517Changes in 1.2.15 (2014-08-14):
1518
1519* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
1520  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
1521  means that we now support all the coordinates systems which Therion does,
1522  except for a few which don't have X=East and Y=North.  The documentation
1523  for *cs has also been improved.
1524
1525* aven: We no longer persist full screen mode between runs - it's not a
1526  standard behaviour of desktop programs, and it's too easy to go into full
1527  screen mode from the menu and then not be able to get out again because you
1528  don't know the required key shortcut. (ticket#39)
1529
1530* aven: When in full screen mode, moving the mouse to the top of the screen now
1531  makes the menu bar appear.  This provides a non-shortcut way out of full
1532  screen mode, as well as making it easier to perform other operations while in
1533  full screen mode.  The current implementation gives an annoyingly flickery
1534  transition, but hopefully we can improve this in future. (ticket#39)
1535
1536* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
1537  development), we now call EnableFullScreenView() which improves the full
1538  screen mode experience on OS X 10.7 and later.
1539
1540* img library: Improve documentation for img_ERROR_INFO.
1541
1542* tests/: Ship some missing .out files and compare.tst.
1543
1544* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
1545  testcase, and extend it to cover a variant of the situation reported as a bug
1546  in therion by Bill Gee to the therion list.
1547
1548* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
1549  for the survex package and on tk for the svxedit package.
1550
1551Changes in 1.2.14 (2014-07-05):
1552
1553* img library: Add ability to store a PROJ4 string describing the coordinate
1554  system in use in 3d v8 files.
1555
1556* aven: If the 3d file specifies a coordinate system, then use it for exporting
1557  to formats which need to know (currently GPX).  If the input file doesn't
1558  specify the coordinate system, allow the user to enter a PROJ4 string in the
1559  export dialog.
1560
1561* aven: You can now quickly zoom to a particular area by holding down the
1562  "Shift" key and dragging with the left mouse button to create a rectangular
1563  "rubber band box" around the area you wish to zoom to.  If you release the
1564  "Shift" key while still dragging, the box is centred on the start point
1565  rather than having one corner there.
1566
1567* aven: Fix exporting of passage tubes in elevations and extended elevations
1568  - previously up and down were getting drawn across the page!
1569
1570* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1571  1.2.13.  (Reported by Brian Clipstone)
1572
1573* aven: Fix the conditions on which the menu item "Cancel measuring line" is
1574  enabled - previously it was hard to actually cancel it via the menu.
1575  Reported by Hugh St Lawrence.
1576
1577* aven: Fix wx assertion failures when showing hit test debug view on platforms
1578  such as 64-bit Linux.
1579
1580* aven: When viewing from above, show "Plan" above the "clino" which indicates
1581  the tilt angle (instead of "Elevation -90°").
1582
1583* aven: The extended font data now loads faster, and also uses less memory on
1584  64-bit platforms.
1585
1586* aven: Dragging the vertical divider between the side panel and the 3D view
1587  now only updates when you finish the drag, as redrawing continuously just
1588  looks clunky except on an ultra-fast machine.
1589
1590* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
1591  the space available in the aven UI.
1592
1593* cavern: Add a *cs command to allow setting the coordinate system for *fix
1594  commands, and the coordinate system used for processed survey data.  The
1595  latter is now stored in 3d v8 format files.
1596
1597* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
1598  and handle it in the same way as the "DUPLICATE" flag in .svx files.
1599
1600* cavern: If there's more than one *fix command with coordinates, still
1601  actually fix the second and subsequent ones, to avoid triggering bogus errors
1602  about unconnected surveys.
1603
1604* cavern: If there's more than one *fix command with coordinates, report the
1605  station name of the previous one, plus the file and line number where it was.
1606
1607* cavern: Fix handling of the rather contrived case of *fix with no coordinates
1608  followed by *solve and then another *fix with no coordinates not to access
1609  freed memory.
1610
1611* dump3d: Report any specified coordinate system.
1612
1613* doc/3dformat.htm: Update to document how the coordinate system is stored.
1614
1615* (Microsoft Windows version): Include dump3d in the installer.
1616
1617* Fix a compiler warning.
1618
1619* Improve test coverage.
1620
1621Changes in 1.2.13 (2014-05-15):
1622
1623* aven: Fix --print option to wait for printing to happen before exiting
1624  (previously it would exit right after opening the print dialog, so you
1625  couldn't actually print anything out using it).
1626
1627* aven: Increase the threshold for how close the pointer needs to be to a
1628  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
1629  Hugh St Lawrence.
1630
1631* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
1632  if increasing the minimum pointer to station threshold helps Hugh's problems
1633  with using aven on a touch screen device.
1634
1635* aven: The measuring line was unable to see stations which had just been
1636  revealed by toggling surface or underground legs on - this is now fixed.
1637
1638* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
1639  many entries are in each box (toggled by F3).
1640
1641* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
1642  off and back on.
1643
1644* aven: Create the empty hit-test grid data structure lazily, to reduce start
1645  up time a little.
1646
1647* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
1648  and *end commands to instead talk about "survey names".
1649
1650* cavern: For ages cavern has warned if you reentered a survey, but this
1651  warning was suppressed if it occurred at the same line of the same file as
1652  the survey was first entered, but this can only happen if you include the
1653  same survey file more than once, which isn't a sensible thing to do for a
1654  file with actual survey data in (you might reasonably do it to set up survey
1655  grade details or something like that).  The warning is now given in this
1656  situation too.
1657
1658* cavern: After 5 warnings about reentering a survey we give up warning about
1659  it, but we used to keep reporting where the survey was originally entered -
1660  this secondary diagnostic message is now silenced when the main message is.
1661
1662* (Microsoft Windows version): Compile C code with optimisation on.
1663
1664* Add the start of a Russian translation, with messages take from therion.
1665
1666* Minor translation updates to French.
1667
1668* Fix compiler warning from GCC.
1669
1670* Testsuite improvements:
1671
1672  + Test that "..." anon station works.
1673
1674  + cavern.tst: Check number of errors returned by all testcases which should
1675    fail and give an error count.
1676
1677  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
1678
1679Changes in 1.2.12 (2014-04-14):
1680
1681* aven: Fix measuring line to show change in altitude rather than altitude
1682  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
1683  Clipstone.
1684
1685* aven: Fix printing when built with wxWidgets 3.0.
1686
1687* aven: Several visual improvements to printouts:
1688
1689  + Move the numbers below the scale bar down a little so that they don't
1690    overlap the scale bar ticks.
1691
1692  + Set the clipping region after we draw the page border and info box to avoid
1693    clipping the border in print preview.
1694
1695  + Tidy up the appearance of the compass and elevation arrow.
1696
1697* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
1698  <http://bugs.debian.org/739332>.
1699
1700* aven: Fix to build with older libav where avcodec_free_frame() isn't
1701  available.
1702
1703* (Linux version) survex.spec: Update spec file used for building RPM packages.
1704
1705* (Unix version): Add "Keywords:" entry to .desktop files.
1706
1707* (Unix version): Enable large file support, mostly to support filing systems
1708  which return 64 bit inode values, such as CIFS mounts.
1709
1710* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
1711  rather than any character which is a letter in the current locale.
1712
1713* Various translation updates.
1714
1715Changes in 1.2.11 (2014-01-28):
1716
1717* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
1718  Reported by Kevin Dixon.
1719
1720* aven: Embed the font data for the first 256 Unicode characters for use in the
1721  survey pane into the compiled aven binary to reduce start up overhead.  Any
1722  additional characters needed are loaded from a data file only if/when a
1723  character >= U+100 is actually needed (as before).
1724
1725* aven: Fix display of Unicode characters above 256 when there's a character
1726  <= 256 earlier in the same string.
1727
1728* aven: Use the actual width of Unicode characters above 256 rather than
1729  assuming they are 16 pixels wide.
1730
1731* aven: If full screen, don't show the side panel when a new file is opened
1732  (e.g. via Ctrl+O).
1733
1734* aven: Don't give an assertion failure when showing passages for a cave with
1735  no vertical extent.  Reported by Jonny Prouty.
1736
1737* aven: Change terminology in print dialog - say "legend" instead of "info
1738  box".
1739
1740* aven: Add option to show the tilt angle as a percentage gradient.
1741
1742* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
1743  indicators.
1744
1745* aven: All length units are now translatable.
1746
1747* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
1748  will reduce code size and also the number of deprecation warnings about
1749  gluErrorString on Mac OS X 10.9.
1750
1751* (Microsoft Windows version): aven: Try to work around redraw issues related
1752  to the measuring line by redrawing the whole window, which doesn't seem to be
1753  measurably slower.
1754
1755* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
1756  give an error rather than quietly ignoring the attempt.
1757
1758* cad3d: Make cad3d remap control characters and spaces in station names when
1759  generating PLT output in the same way aven does.
1760
1761* Various translation updates (particular thanks to Eric Madelaine and Dennis
1762  Baudys), including the start of a Bulgarian translation, with messages taken
1763  from Therion and elsewhere.
1764
1765* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
1766  GetUserDefaultUILanguage() to get the UI language to use.  For older
1767  versions, continue to use GetUserDefaultLCID().
1768
1769* (Microsoft Windows version): The Indonesian translation will now be used
1770  automatically when the system language is set to Indonesian.
1771
1772* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
1773  A. Riggs for his work on this.
1774
1775* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
1776  checksum check for the downloaded wx sources.
1777
1778* Fix a lot of the compiler warnings when building with clang.
1779
1780* doc/manual.sgml: Add missing quantities to the list documented as accepted by
1781  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
1782  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
1783  mentioned in list of the units that can be set for them); COUNT (missing
1784  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
1785  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
1786
1787* Test suite: Improve test coverage for cavern.
1788
1789Changes in 1.2.10 (2014-01-15):
1790
1791* aven: Fix assertion if two mouse buttons are held down at the same time.
1792  If dragging with more than one mouse button held down, releasing one causes
1793  another which is still held down to take effect.  Reported by Brian
1794  Clipstone.
1795
1796* aven: If we fail to start the external editor when the user clicks on an
1797  error or warning from cavern, show an error box.
1798
1799* aven: If the survey has a title, add it as a top-level <title> element to
1800  exported SVG files.
1801
1802* aven: Escape '<', '>', and '&' in labels in exported SVG files.
1803
1804* aven: In GPX export, set the <time> element to the datestamp from the 3d
1805  file.
1806
1807* aven: Don't try to write the title if it isn't set or is empty when exporting
1808  GPX files.
1809
1810* aven: Don't bother looking up the printer page setup info when exporting.
1811
1812* (Microsoft Windows version): aven: Fix crash on "File->Print" or
1813  "File->Export" under Windows XP, reported by Brian Clipstone.
1814
1815* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
1816  encoded filename which could occur if run without being asked to load a file
1817  on startup.
1818
1819* (Microsoft Windows version): aven: Compile with optimisation on.
1820
1821* img library, aven: Although processed CMAP data files are often referred to
1822  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
1823  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
1824  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
1825  continue to do so in case anyone is relying on it, but also check for the
1826  other extensions.
1827
1828* img library: Add new "datestamp_numeric" field to struct img giving the
1829  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
1830  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
1831  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
1832  timezone wrong.
1833
1834* img library: Fix my_strcasecmp() to handle top-bit set characters better.
1835
1836* cavern: Fix NULL pointer dereference when processing Compass DAT file without
1837  'SURVEY DATE:'.
1838
1839* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
1840
1841* doc/manual.sgml: Note the station length limit Smaps used.
1842
1843* Fix some compiler warnings if built with glibc's fortify source feature
1844  enabled.
1845
1846Changes in 1.2.9 (2014-01-08):
1847
1848* Document --3d-version in cavern man page and the manual.
1849
1850* aven: Fix compilation error in movie export code with recent libavi.
1851
1852* aven: Fix warning on stderr when export a movie as MPEG.
1853
1854* img library: In non-hosted mode, don't define GETC and PUTC if they're
1855  already defined, to allow easy overriding with getc_unlocked() and
1856  putc_unlocked() (which are significantly faster on Linux).
1857
1858* img library: In non-hosted mode, check that int is at least 32 bits,
1859  and if not, use long.  In practice, platforms with 16 bit int are mostly
1860  obsolete, but it's not hard to be portable here.
1861
1862* img library: Add test that img.c and img.h compile in non-hosted mode
1863  (regression test for issue fixed in 1.2.8).
1864
1865* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
1866
1867* Update translations from launchpad and from existing similar messages.
1868
1869* Fix some compiler warnings.
1870
1871Changes in 1.2.8 (2013-10-29):
1872
1873* cavern: Fix handling of anonymous wall stations ('..' by default) to
1874  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
1875  Holder.
1876
1877* cavern: Tweak .err file output not to lose the space in front of certain
1878  statistics when the value gets large.
1879
1880* cavern: Eliminate redundant progress message when solving simultaneous
1881  equations.
1882
1883* aven: Add a format drop down to the export dialog, and only show fields which
1884  are meaningful and supported for the currently selected export format.  The
1885  format defaults to that used most recently.  The "Elements" and "View" boxes
1886  have been swapped in the print and export dialogs as that layout works much
1887  better when the "View" box is hidden.
1888
1889* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
1890  - now works again.  Reported by Anthony Day.
1891
1892* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
1893  this release the projection which the survey coordinates are in defaults
1894  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
1895  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
1896  projection string.  The ability to specify this projection in a better
1897  way is coming soon.
1898
1899* aven: New export options "Origin in centre" and "Full coordinates" - the
1900  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
1901
1902* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
1903  time ago, so update references.
1904
1905* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
1906  with wxMSW 2.9.5.  Reported by Brian Clipstone.
1907
1908* aven: Make right click in an empty presentation mark the current position and
1909  open it to edit, instead of crashing.
1910
1911* aven: Update movie export code to work with latest libav API.  Reported by
1912  Sebastian Ramacher.
1913
1914* aven: Improve reporting of errors during the process of exporting a movie.
1915
1916* aven: Don't try to close the movie if we aren't producing one.
1917
1918* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
1919
1920* aven: Fix to build with wxMSW 2.9.5.
1921
1922* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
1923
1924* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
1925  ago, so add a new --skencil option to specify this output format.  The old
1926  name (--sketch) is still recognised for compatibility.
1927
1928* cad3d: Make --marker-size work for Skencil and SVG output.
1929
1930* dump3d: Make --show-dates option show dates for XSECT.
1931
1932* img library:
1933
1934  + Fix to work once more when used outside of Survex (missing definition of
1935    max() macro and a bad call to free() in img_close() for a file opened for
1936    reading).
1937
1938  + Use lround() instead of round(), and make the tests around whether we use
1939    the library function or the our fallback implementation saner.
1940
1941  + Fix // comments in C code for portability to pre-C99 compilers which don't
1942    support these as an extension.
1943
1944  + Can now be compiled as C++ as well as as C.
1945
1946* (Microsoft Windows version): The installer is now built with a newer version
1947  of Innosetup, and includes translations for all the languages which Survex
1948  itself has any translations for.
1949
1950* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
1951
1952* Minor translation updates.
1953
1954* tests/Makefile.am: Distribute files for "normal_bad" testcase.
1955
1956Changes in 1.2.7 (2013-07-27):
1957
1958* Add support for anonymous stations, which are indicated by one, two or three
1959  separator characters - with the default separator of '.', that means '.',
1960  '..', and '...' are anonymous stations.  Single separator ('.' by default)
1961  is an anonymous non-wall point, double separator ('..' by default)
1962  is an anoymous wall point at the end of an implicit splay), and triple
1963  separator ('...' by default) is an anoymous point (with nothing special about
1964  the leg).  A new *alias command allows '-' to be mapped to '..' for
1965  compatibility with pocket topo: *alias station - ..
1966
1967* New version 8 of the 3d format:
1968
1969  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
1970
1971  + New explicit file-wide flag for 'this is an extended elevation', rather
1972    than modifying the survey title to indicate this.
1973
1974  + The survey prefix is often unchanged from one leg to the next, so use a
1975    spare flag to compactly indicate when there's no label change.
1976
1977  + The data style of each leg is now stored.
1978
1979  + The "processed at" time is stored as seconds since 1970 rather than a
1980    human-readable string.
1981
1982  + Since 3d v8 features significant changes to the format, the format
1983    documentation for v7 and earlier has been split off into 3dformat-old.htm.
1984
1985* img library:
1986
1987  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
1988
1989  + Handle .pos files containing unnamed stations - don't suck the next line in
1990    as the station name, and set img_SFLAG_ANON for them.
1991
1992  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
1993    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
1994    elevation, in place of appending " (extended)" to the title.  Internally we
1995    still append this to the title (and remove it upon reading) when writing
1996    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
1997    explicitly in the file.
1998
1999  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
2000
2001* aven:
2002
2003  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
2004    now, and the wx developers consider even 2.8 to be rather long in the
2005    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
2006    formally dropping support for older versions allows a number of workarounds
2007    to be removed from the aven source code.  Also, features deprecated in
2008    wxWidgets 2.9 are no longer used in our code.
2009
2010  + Don't run incremental search on every key-press, as on a slow machine the
2011    short initial search(es) will take a while but not be useful.  Instead only
2012    actually run the search when we're told there are no more key-presses
2013    queued up.
2014
2015  + Implement support for including cross-section information in exported SVG
2016    and DXF files (ticket#4).  The DXF export is untested currently.
2017
2018  + Show splay legs faded by default, with menu options to hide them or show
2019    them like other legs.
2020
2021  + Speed up loading a .3d file with cross-sections by using a map to convert
2022    station names to positions.
2023
2024  + In the cavern log window, don't highlight a file:linenumber if there's no
2025    message after it, which avoids highlighting the "Included from" lines
2026    wrongly.
2027
2028  + Fix not to crash when trying to report an error while starting up.
2029
2030  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
2031    the OS X standard shortcut Shift-Command-F (previously we used F11, but
2032    that's used by the desktop).
2033
2034  + Add checks for errors when reading the font file.
2035
2036  + Remove useless extra quoting when invoking vim to show the location of an
2037    error from cavern.
2038
2039  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
2040
2041  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2042    in the dialog in sync.
2043
2044* cavern:
2045
2046  + Demote errors about invalid dates to warnings, since we've accepted *date
2047    for ages without any checks on the value, and so existing datasets
2048    probably contain invalid dates and dates in other formats.  (ticket#19)
2049
2050  + New *alias command allows '-' to be mapped to '..' for compatibility with
2051    pocket topo: *alias station - ..
2052
2053  + We want to warn if there's a clino reading which it would be impossible to
2054    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2055    read "93" (it's probably a typo e.g. for "39").  However, the gradient
2056    reading from a topofil is typically in the range 0 to 180, with 90 being
2057    horizontal.  Really we should allow the valid range to be explicitly
2058    specified, but for now we infer it from the zero error - if this is within
2059    45 degrees of 90 then we assume the instrument can read between 0 and 180
2060    degrees.
2061
2062  + If the survey isn't all connected, still run survey tree checks and report
2063    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
2064    Dixon for the report which highlighted this issue.
2065
2066  + Report a warning if *begin SURVEY has a separator character in SURVEY.
2067
2068  + Report column numbers as well as line numbers for some cavern errors and
2069    warnings.
2070
2071  + Adjust width of node stats table to fit longest count when there are more
2072    than 9999 of a particular order of node.
2073
2074  + If the argument to *include has an opening double quote but the closing
2075    double quote is missing, then skip trying to open the file.
2076
2077  + Move "Station X referred to just once" warning after non-existent survey
2078    check - if both fire, the non-existent survey error is likely to be more
2079    relevant.
2080
2081  + We no longer follow an error for a bad reading in passage data with a bogus
2082    "End of line not blank" error, but instead check the remaining readings on
2083    the same line.
2084
2085  + We no longer follow an error about OMIT for a required reading with a bogus
2086    "End of line not blank" error.
2087
2088  + Report an error if the scale factor in *calibrate is zero - it doesn't make
2089    sense and probably means someone reversed the arguments to *calibrate.
2090
2091  + Report the parent include files starting from the outermost, as that's more
2092    logical when there are multiple levels involved.
2093
2094  + If we were expecting a numeric field and instead get something which starts
2095    with '+', '-', or '.' but which isn't a number, then fix the error to
2096    include that character in the token reported.
2097
2098  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2099    first item.
2100
2101* cad3d: Check for errors from img_rewind() and report them.
2102
2103* dump3d:
2104
2105  + Build, install and package dump3d as standard - it's useful for grabbing
2106    info from 3d files in scripts.
2107
2108  + Add --show-dates option.
2109
2110  + Show only 2 decimal places on coordinates and passage dimensions.
2111
2112  + Report the data style of legs.
2113
2114  + Report if the file is an extended elevation.
2115
2116  + Report img_STOP as STOP rather than CODE_0xffffffff.
2117
2118* Test suite:
2119
2120  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2121    expected output so it passes reliably.
2122
2123  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2124    'Deleted' stations upon failure are the more natural way round.
2125
2126  + Add more testcases, expand some existing testcases, and add expected output
2127    for more.
2128
2129* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2130  appropriate C and C++ compilers to use, and link mingw build statically to
2131  avoid needing the libgcc DLL (which newer GCC seems to have by default).
2132
2133* (Unix version): When determining the character set for command-line tools,
2134  check environmental variable LANG after LC_ALL and LC_CTYPE.
2135
2136* When determining the language, check environmental variable LC_ALL before
2137  LC_MESSAGES and LANG (but after SURVEXLANG).
2138
2139* If we don't find the message file, only give an error if it was specified
2140  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
2141  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2142  settings.
2143
2144* There are a handful of hard-coded English message strings for reporting
2145  errors trying loading message files, etc.  These are all now ASCII, as if we
2146  fail trying to open a message file, it's more likely the encoding isn't
2147  set correctly.
2148
2149* Prune strings we are no longer using and are probably unlikely to use again
2150  into a new file po_codes_dead, so that translators don't get presented with
2151  them to translate.
2152
2153* Merge lots of translation updates.  Most translations are now complete or
2154  close to complete.
2155
2156* Add start of Indonesian translation from Arief Setiadi Wibowo.
2157
2158* Fix various compiler warnings when building from source.
2159
2160* Include scripts gdtconvert and gen_img2aven in the source distribution.
2161
2162Changes in 1.2.6 (2012-02-23):
2163
2164* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2165
2166* (Microsoft Windows version): Include JPEG images for aven in the installer
2167  package (ticket#35).
2168
2169* cavern: If we have a reference to a station in a non-existent survey, give a
2170  helpful error rather than saying the station hasn't been exported from the
2171  survey.  (Bug reported by Martin Green via email)
2172
2173* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
2174  Kahler.
2175
2176* findentrances: Add findentrances utility from Olaf Kahler which produces a
2177  .gpx file with waypoints for entrances.  This needs libproj so is disabled
2178  by default for this release - to enable it install the development stuff for
2179  libproj and build survex with:
2180
2181      make FINDENTRANCES=findentrances
2182      make install FINDENTRANCES=findentrances
2183
2184* dump3d: Add support for showing img_ERROR_INFO items.
2185
2186* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2187
2188* Incorporate a French translation from launchpad I'd previously copied the
2189  English version of by mistake.  Attempt to correct mistranslation of "survey
2190  file".
2191
2192Changes in 1.2.5 (2012-01-03):
2193
2194* aven:
2195
2196  + The survey tree in the left panel is now in sorted order once more.
2197
2198  + No longer fails with an assertion if used for a long time (we were leaking
2199    an OpenGL list each time one had to be regenerated).
2200
2201  + Now builds with newer FFmpeg library.
2202
2203  + Draw measuring line in front of the indicators rather than behind them.
2204
2205  + Loading a new file (or reloading the current one) no longer invalidates
2206    the OpenGL lists for the compass and clino, so will be a fraction faster.
2207
2208* Improve handling of attempts to look up translated messages before the
2209  message subsystem is fully initialised (which only happens if there's an
2210  error early on).
2211
2212* Improve the survex(7) man page text, and fix it to be marked as section 7 in
2213  the man page source as well as in the filename.
2214
2215Changes in 1.2.4 (2012-01-01):
2216
2217* aven:
2218
2219  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2220    initialised, which doesn't cause problems in some machines, but causes aven
2221    to abort on others.  This is now fixed, and there's a check in place to
2222    help avoid similar issues in future. (ticket#34)
2223
2224  + Always use metres or feet for the depth colour key, and chose a consistent
2225    precision by looking at the depth range. (ticket#30)
2226
2227  + Show the depth units below the colour bar rather than after every value.
2228
2229  + When zooming way in, stay in metres rather than switching to cm.
2230
2231  + On the scale bar, say “1 mile” rather than “1 miles”.
2232
2233* Translation updates for Catalan, French and Slovak.
2234
2235Changes in 1.2.3 (2011-12-31):
2236
2237* Fix to build with wxWidgets 2.9.2.
2238
2239* (Mac OS X version):
2240
2241  + Processing .svx files from aven now works.
2242
2243  + Remove spurious blank lines from the licence text in "Get Info".
2244
2245  + Don't create the help menu at all, as it is empty (because the "About"
2246    entry goes elsewhere) and sometimes seems to appear in the UI.
2247
2248  + INSTALL.OSX: Update to reflect current status.
2249
2250* aven:
2251
2252  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
2253
2254  + Improvements to text plotted on the survey pane:
2255
2256    - Support plotting Unicode character points > 256 by lazily loading the
2257      data for them from the font file and plotting them with a direct call to
2258      glBitmap(), which is slower but doesn't require a display list per
2259      character.
2260
2261    - Adjust the spacing from fixed width to putting a one pixel gap either
2262      side of each one character (so two between adjacent glyphs).  Mostly this
2263      reduces the horizontal width, but it adds a pixel for characters like "m"
2264      and two in a few cases.
2265
2266    - Fix .pixelfont file generation to correctly handle characters wider than
2267      8 pixels.
2268
2269  + Fix expected cross shape so don't always reject using texture mapping to
2270    draw crosses.
2271
2272  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2273    as those consisting of just one.  Previously we would trip over the empty
2274    tube later.  Such tubes can for example be created by extend if a splay shot
2275    is the start or end of a tube.
2276
2277  + Make the green colour used for entrances in the survey tree the same
2278    (slightly darker than before) green used for the entrance blobs.
2279
2280  + Report the version of the library we're actually running with if built
2281    against wx >= 2.9.2.  Make it clear that the version reported is the
2282    version *built* with for wx < 2.9.2.
2283
2284* extend:
2285
2286  + Copy the end markers for passage tubes.
2287
2288  + Preserve left and right data for tubes (previously they were set to -1.0
2289    which means "no info").
2290
2291* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2292  was no longer used - it certainly is!
2293
2294* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2295  messages, and curly single right quote instead of straight ASCII apostrophe.
2296  Fall back to using straight ASCII versions if we can't represent them in the
2297  current character set.
2298
2299* Translation updates for Catalan, French, Slovak and Spanish.
2300
2301* Test suite:
2302
2303  + Add test coverage for interleaved diving data.
2304
2305  + Add testcase for diving data with topofil-style distance.
2306
2307Changes in 1.2.2 (2011-10-06):
2308
2309* aven:
2310
2311  + Replace the textured-mapped font drawing with an approach based on
2312    glBitmap.  This doesn't suffer from the character alignment issues which
2313    the textured-mapped fonts had, and is actually significantly faster on some
2314    machines.  The current font used is (mostly) fixed-width, but this isn't an
2315    inherent limitation - it was just the easiest font data to convert to a
2316    usable format.
2317
2318  + Fix assertion failure due to rounding differences on loading certain .3d
2319    files.  (ticket#26)
2320
2321  + Fix assertion failure when turning on 3D passages if they stick out higher
2322    or lower than any station.  (ticket#29)
2323
2324  + Fix grid not to disappear when blobs are turned on and blobs are drawn
2325    using lines.
2326
2327  + If a degree sign isn't available in the character set in use, transliterate
2328    it to 'dg' rather than skipping it.
2329
2330  + Fix message which should have been a degree sign but got lost in the format
2331    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
2332    that bearings in the status bar now have a degree sign after them if they
2333    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2334
2335  + Fix print dialog to calculate the scale required for "One page" right
2336    before it calculates how many pages are required, so we don't end up
2337    something other than 1x1 being shown when the user changes settings.
2338
2339  + Update the calculations for picking a scale and for deciding how many
2340    pages are needed to take into account the change in info box height made
2341    in 1.2.1.
2342
2343Changes in 1.2.1 (2011-10-04):
2344
2345* Translation updates for US English.
2346
2347* aven:
2348
2349  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2350    it now shows colours for dates and errors as well as depths.
2351
2352  + In the colour key for "colour by date", change "No info" to "Undated".
2353
2354  + Remove the dark grey background from the colour key and just put a single
2355    pixel black border around the colours.  This is more in keeping with the
2356    other controls, and means the colours are now on a black background so more
2357    visually similar to the survey legs.
2358
2359  + Move the colour key's "Undated"/"Not in loop" entry down a little to
2360    improve the appearance.  Make each section a pixel taller.
2361
2362  + Allow "Colour by X" to be selected even if there's no data for X or only a
2363    single value of X used (the colour key is much smaller in these cases, and
2364    does still provide some useful information).
2365
2366  + Fix incorrect calculation of depth colouring for survey legs which straddle
2367    a depth band boundary.
2368
2369  + The scale bar, compass, clino, and colour key now all have right click
2370    menus which allow related actions to be performed (especially handy in
2371    full-screen mode).
2372
2373  + Improve the font used on the survey pane - it now contains the '-'
2374    character (so the clino now shows negative angles as negative, and dates
2375    in the colour key are now hyphenated).  Also the spacing and alignment
2376    are a little better, though still not perfect.
2377
2378  + PLT file export now handles spaces and control characters in station names
2379    by escaping them with '%' as in URLs.
2380
2381  + Pressing "Enter" on a station in the tree control now centres the view on
2382    that station.
2383
2384  + The scale bar is now cached in an OpenGL display list since it often gets
2385    redrawn exactly the same - for example, when rotating, panning, etc.
2386
2387  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2388    then forces a refresh of the survey pane.  This is intended as a debugging
2389    aid - if pressing F5 changes the display at all then there's a missing case
2390    where a list should have been invalidated (please report if you find such
2391    a case as it is a bug).
2392
2393  + We now automatically track which OpenGL display lists need to be
2394    invalidated on window width or height changes.
2395
2396  + Increase scale bar maximum width from 65% of the window width to 75% as it
2397    was in 1.0.x (except that if that would overlap the clino we now reduce
2398    that proportion down until it reaches 50%).  Make the limit of zooming in
2399    the same as in 1.0.x.  (ticket#23)
2400
2401  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2402    the application was fullscreen (the dialog got opened under the main
2403    window!)  To work around this, aven would switch out of full screen mode
2404    temporarily while showing a dialog.  This case works properly with recent
2405    wxGTK, so disable our workaround with versions we know work.  Also, apply
2406    the workaround only for wxGTK, not everywhere except on Microsoft Windows
2407    as there's no reason to think we need it for other platforms.
2408
2409  + Grey out the "View North" action when we're already viewing North, and
2410    similarly for other compass points.
2411
2412  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
2413    info in the "About" dialog.
2414
2415  + Fix to set the correct filename on the root of the survey tree - previously
2416    the filename of the previous file loaded was used!
2417
2418  + The movie export code now works with newer versions of the FFmpeg libraries
2419    as well as still working with older versions.
2420
2421  + Fix mixed up messages - the print dialog now says "View" on the left
2422    subgroup of controls rather than some unrelated message.
2423
2424  + On printouts, combine the "Plan View"/"Elevation" info box field with the
2425    field which gives the bearing and reduce the height on the info box by the
2426    removed field, so it's now 3cm for plans and elevations, as for extended
2427    elevations.  Report the tilt angle for tilted elevations which it seems has
2428    been missing for ages (it's not in recent 1.0.x either).
2429
2430  + Tweak the exact positioning of informational text on printouts to look
2431    nicer and make better use of the available space.
2432
2433  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
2434    dialog.
2435
2436  + Make the sign of the tilt angle for printouts consistent with the sign
2437    shown by the "clino" in the survey pane.
2438
2439  + In the "Print" dialog, when in plan view disable the "Plan view" button,
2440    and similarly for the "Elevation" button.
2441
2442  + (Microsoft Windows version): Sort out appearance of custom cursors.
2443
2444  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
2445
2446  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
2447    you can't get out again easily, so add code to explicitly check for F11
2448    being pressed and toggle full screen.
2449
2450* (Linux version): Fix the RPM .spec file for where man pages now get installed
2451  and package aven.svg and the vim support files.  (Fixes from James Begley)
2452
2453* "make check" now performs several checks on the translation files.
2454
2455* More messages are now available to be translated.
2456
2457* cavern: Fix reporting of ranges of survey coordinates, which was broken by
2458  the message handling changes in 1.2.0.
2459
2460* Fix warning when compiling with GCC.
2461
2462* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
2463  sudo for installing on Unix.
2464
2465* In the manual, replace the instructions for building from source with a
2466  pointer to the clearer instructions in INSTALL.
2467
2468* In the manual, make it clear that installing with administrator rights
2469  also applies to newer platforms than XP.
2470
2471* doc/TODO.htm: Update.
2472
2473Changes in 1.2.0 (2011-09-20):
2474
2475* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
2476  English.
2477
2478* tests/smoke.tst: aven no longer requires an X display for --help or
2479  --version, so replace skip of this check with a check that this remains the
2480  case.
2481
2482* We now use the standard .po and .pot file formats for storing translations
2483  (rather than the Survex-specific messages.txt format), and then translate
2484  these into Survex's .msg format.
2485
2486* (Unix version): Move survex man page to section 7 (since it isn't documenting
2487  an actual command).
2488
2489* (Unix version): Write each generated man page to a temporary file, then
2490  atomically rename, to avoid leaving an empty or partial man page behind if
2491  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
2492  recurrence of that).
2493
2494* (Unix version): Default to installing docs into /usr/share/doc/survex rather
2495  than /usr/doc/survex.
2496
2497* aven:
2498
2499  + Fix handling of accented characters in the survey pane.
2500
2501  + Aven icon redrawn in SVG format - it's now a vector image which looks
2502    nicer at larger sizes.
2503
2504  + Explicitly request double-buffering, which seems to be needed for systems
2505    with GLX >= 1.3.
2506
2507  + Fix crash while trying to load certain .3d files.
2508
2509  + Movie export code updated to work with more recent versions of FFmpeg.
2510    Currently this is disabled in Microsoft Windows builds, pending getting the
2511    required libraries set up for building releases.
2512
2513  + Reporting of errors during movie export improved.
2514
2515  + Force playback speed to "x1" during movie export.
2516
2517  + Use stock IDs for buttons where appropriate - such buttons may now be
2518    rendered with icons on some platforms.
2519
2520  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
2521    ISO8859-1).
2522
2523  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
2524    as it's no longer required with modern versions.
2525
2526  + Don't redraw the survey on every mouse movement in the survey pane unless
2527    the measuring line is (or just was) active.  (ticket #17)
2528
2529* cavern:
2530
2531  + Drop "non-fatal" from the report of how many errors there were at the end
2532    of the run - it just confuses users - we won't even get here if there's a
2533    fatal error!
2534
2535  + Add --3d-version option to allow the user to specify the version of the 3d
2536    format to output.  (ticket#21)
2537
2538* img library:
2539
2540  + Make the highest and lowest valid values for img_output_version available
2541    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
2542
2543* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
2544  volume actually gets mounted.  Fix URL for downloading wxWidgets.
2545
2546Changes in 1.1.16 (2011-05-16):
2547
2548* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
2549  Portuguese, and US English.
2550
2551* Use horizontal ellipses character rather than '...' and right arrow character
2552  rather than '->' where these characters are available.
2553
2554* (Unix version): Link with -lGL, if it exists, to support linking with gold or
2555  GNU ld --as-needed (Debian bug #615781).
2556
2557* img.c:
2558
2559  + Fix code typo for IMG_API_VERSION == 0 case.
2560
2561  + Fix code typo in code used when IMG_HOSTED isn't defined.
2562
2563* doc/TODO.htm: Remove entries which have now been done.
2564
2565* (Microsoft Windows version): aven: We now include all the available
2566  translations for messages from wxWidgets, which means that standard widgets
2567  will appear translated where available even if Survex messages aren't
2568  translated.
2569
2570Changes in 1.1.15 (2010-10-15):
2571
2572* aven:
2573
2574  + In the cavern log window, change the "Rerun" button to "Reprocess" to
2575    follow terminology in manual and elsewhere.  Fixes ticket#15.
2576
2577  + When displaying output from cavern, don't update the window after every
2578    line, but only when we don't have data from cavern pending.  Hopefully
2579    addresses ticket#12.
2580
2581  + If we aren't using GL_POINTS for blobs, draw them using a series of
2582    abutting lines rather than with gluDisk which is faster and gives a
2583    consistent shape.
2584
2585  + Check whether blobs and crosses actually render correctly as points/point
2586    sprites, and if they don't, fall back to drawing them with lines.  The
2587    best method is cached on disk, and rechecked automatically if the graphics
2588    hardware is changed or the drivers upgraded.
2589
2590  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
2591    though, so we still enable USE_FNT by default).
2592
2593  + Don't offer "All files" wildcard in presentation save dialog.
2594
2595  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
2596    more places.
2597
2598  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
2599    when running cavern from aven.  Fixes ticket#11.
2600
2601* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
2602
2603* diffpos: Handle files with duplicate labels in better - extend generates
2604  duplicate labels when it breaks a loop.
2605
2606* Enable eswap-break testcase now that diffpos handles duplicate station names.
2607
2608* New v7 of .3d format which stores survey dates as number of days since
2609  January 1st 1900, so we now support dates from 1900-2078 (rather than
2610  1970-2037) with a smaller file size.  The img API is now versioned - you
2611  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
2612  gives the survey dates in days in days1 and days2 instead of as time_t
2613  values in date1 and date2.  Fixes ticket#14.
2614
2615* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
2616  former has been the canonical name for some time, with www.survex.com just
2617  redirecting to it.
2618
2619* (Unix version): Use unlocked file I/O if available, which can be much faster
2620  in some cases (we don't need the locking as we don't do multithreaded file
2621  I/O).
2622
2623* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
2624  headers.
2625
2626* (Mac version): buildmacosx.sh now works again.
2627
2628* Most tests weren't actually running any testcases (looks like a sh
2629  portability issue).  This is now fixed, and fortunately all tests still pass.
2630
2631* Include the extra .isl translation files for Innosetup in the source archive.
2632
2633Changes in 1.1.14 (2010-07-26):
2634
2635* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
2636
2637* aven:
2638
2639  + After processing survey data, if there were warnings or errors, add a
2640    "Rerun" button to allow easy reprocessing after fixing problems.  If there
2641    were only warnings, also add an "OK" button to allow moving on to viewing
2642    the processed survey data (fixes ticket#13).
2643
2644  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
2645
2646  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
2647    not the ': ' after), and to make the title for the terminal the
2648    warning/error message.  Avoid false positives by checking that '<line>' is
2649    a number.
2650
2651  + Don't double escape the contents of href and target in links in the cavern
2652    log window.
2653
2654  + Improve handling of the splitter window, fixing behavioural glitches in
2655    various cases.
2656
2657  + Highlight stations matching any current search when a file is loaded.
2658    (ticket#9)
2659
2660  + (Mac version): Fix build issue due to Mac OS X polluting the global
2661    namespace with its own "Point" class.
2662
2663  + (Unix version): The Gnome print dialog has its own preview window so
2664    suppress ours if using the Gnome one.
2665
2666  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
2667
2668  + (Microsoft Windows version): Fix handling of a double-click on the survey
2669    tree when built with wxWidgets >= 2.8.11.
2670
2671* cavern: Report relevant file and line number for three warnings which didn't
2672  give them before.
2673
2674* (Unix and Mac versions): configure: Update the wx-config probing code -
2675  wxmac-config etc aren't present with newer wxWidgets versions so there's no
2676  point looking for them now.
2677
2678* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
2679  for easy installation.  Update it to work with the latest Survex versions
2680  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
2681  private wxWidgets, use 2.8.11 not 2.7.0-1).
2682
2683* manual:
2684
2685  + Correctly capitalise "GTK".
2686
2687  + Note that on Linux we only regularly test builds with the GTK+ version
2688    (change taken from 1.0).
2689
2690* Fixed the cad3d man page, which was an empty file in 1.1.13.
2691
2692Changes in 1.1.13 (2010-06-16):
2693
2694* Say "wxWidgets" instead of "wxWindows" consistently.
2695
2696* img.c: Fix small memory leak (filename_opened member).
2697
2698* cad3d, aven: Fix export to SVG when a label contains a '%' character.
2699
2700* aven:
2701
2702  + wxWidgets 2.6.0 or newer is now required.
2703
2704  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
2705    work but hasn't been tested recently (all packaged versions of wxWidgets
2706    seem to be Unicode now).
2707
2708  + Fix potential uses of uninitialised variables which may have been causing
2709    occasional glitches when loading a file on start-up.
2710
2711  + Improvements to the handling of the font used for plotting labels and other
2712    text on the survey pane:
2713
2714    - Loading the font file is more efficient.
2715
2716    - Character spacing is improved.
2717
2718    - Default font is now anti-aliased.
2719
2720  + "About" dialog:
2721
2722    - Add "Copy" button to copy the system info to the clipboard for easier
2723      bug reporting.
2724
2725    - List OpenGL extensions last, since there are usually lots of them with a
2726      modern gfx card.
2727
2728    - Fix 100% CPU usage while the "About" dialog is open.
2729
2730  + Processing .svx files:
2731
2732    - Passing a .svx file on the command line now works better.
2733
2734    - Put the survey data log window in a splitter in the usual frame rather
2735      than opening a separate frame for it.
2736
2737    - Auto-scroll the log window until we've reported a warning or error.
2738
2739    - Fix small memory leak.
2740
2741  + The presentation filename now defaults to using the basename of the
2742    currently loaded dataset, but we always prompt before we first save with
2743    such a name.
2744
2745  + Reduce memory usage when saving a screenshot.
2746
2747  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
2748    persist the window size (and maximised or fullscreen state) between
2749    invocations.
2750
2751  + Fix reporting of OpenGL errors.
2752
2753  + Fix glitches when tilting while looking East.
2754
2755  + Added Portuguese and Slovak translations of wxWidgets messages.
2756
2757* Documentation:
2758
2759  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
2760
2761  + Drop the "alternative manual formats" self-extracting zip file - people
2762    will generally just want one of the formats, so downloading several
2763    together isn't very useful.
2764
2765  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
2766
2767  + GPL.htm: Replace HTML version of licence with a link to the version on
2768    the FSF website.
2769
2770  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
2771    low level to be of interest to non-developers, and developers can look at
2772    the source code.
2773
2774* (Unix version): configure: New preferred name for specifying wx-config script
2775  is WX_CONFIG.  WXCONFIG still supported for compatibility.
2776
2777* (Linux version): Source RPM package dropped as you can just build an RPM
2778  package from the source tarball.
2779
2780* (Microsoft Windows version): The installer is now created with a newer
2781  version of InnoSetup, which gives a 10% smaller download.
2782
2783Changes in 1.1.12 (2007-02-07):
2784
2785* aven:
2786
2787  + Remember the window size or maximised/fullscreen state between invocations.
2788
2789  + Add options dialog to "Export" similar to the one for "Print".
2790
2791  + The "number of pages required" in the print dialog now updates when you
2792    change what is to be shown (underground legs/surface legs/station
2793    names/crosses).
2794
2795Changes in 1.1.11 (2006-11-25):
2796
2797* Updated Czech, Spanish, and Slovak translations.
2798
2799* (MacOS X version): Assorted OS X specific tweaks and fixes.
2800
2801* aven:
2802
2803  + Pick a smaller and clearer font for labels.
2804
2805  + Fix character spacing.
2806
2807  + Tweak display of bearing and elevation angles to look nicer with
2808    proportional fonts.
2809
2810  + Use the title from the 3d (or plt, etc) file for the window title
2811    rather than the filename.
2812
2813  + Show distances to 2 decimal places rather than the nearest integer.
2814
2815  + Only consider underground legs when calculating the depth bands and
2816    depth colouring.
2817
2818  + Add "Colour by Error".
2819
2820  + Add entry for "white" in date and error keys.
2821
2822  + When setting the view to a single point, don't change the scale.
2823
2824  + If reloading the same file, don't change the view
2825
2826  + Fix filetypes selector in open dialog.
2827
2828  + Fix the charset we use for aven in certain cases.
2829
2830  + Call msg_init before using msg_lang or it won't ever be set!
2831
2832  + Pass wx the full language code to initialise the C library locale.
2833
2834  + Fix bug in generating prefix tree view which could lead to a bogus
2835    leading dot on some survey names (bug probably introduced in 1.1.10).
2836
2837  + "New Presentation" now ensures that the side panel is open
2838
2839  + Fix updating of cached opengl lists when the view is reset to the
2840    default.
2841
2842* Ignore LANG if it starts with a digit to avoid problems with bogus value for
2843  LANG which AutoCAD installation seems to set on MS Windows.
2844
2845* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
2846  specified.  Either/both can be set to ":".
2847
2848* dump3d: Report unknown (to dump3d) codes returned by img.
2849
2850* img library: Flag all stations as underground in the old "ASCII" .3d format.
2851
2852Changes in 1.1.10 (2006-07-14):
2853
2854* aven: Clicking on a survey name in the survey tree now highlights it in
2855  the map view.  Double-clicking zooms the view to show the clicked survey
2856  highlighted.  Clicking the root clears the highlighting and double-clicking
2857  the root restores the default view.  To expand/collapse a branch, click
2858  on the "[+]" or "[-]" icon to the left of the survey name.
2859
2860* aven: The measuring line can now measure to anywhere in plan or elevation
2861  view (not just to a station!)  In plan view the horizontal distance and
2862  bearing are shown, while in elevation view the vertical distance is shown.
2863
2864* aven: Moving the mouse over a station in the survey view now highlights
2865  that station in the survey tree (though it may not be visible if the
2866  survey(s) it is in aren't expanded).
2867
2868* aven: Clicking on a station to centre the view now moves the mouse pointer
2869  to the new location of the station (except on Mac OS X where this isn't
2870  allowed).
2871
2872* aven: Fix which presentation toolbar buttons are shown as depressed.
2873
2874* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
2875
2876* vim files are now installed with the correct paths (bug introduced in 1.1.9).
2877
2878Changes in 1.1.9 (2006-07-04):
2879
2880* (Unix version): Install desktop files for aven and svxedit contributed to the
2881  Ubuntu package by Phil Bull, and corresponding pixmaps.
2882
2883* Fix img to filter out cross-sections which don't match the subsurvey (if
2884  specified).  The API now returns img_XSECT_END to mark the end of a
2885  passage rather than setting a flag on the last img_XSECT of the passage.
2886
2887* Enhance integration with the vim editor - this can now colour .err files, run
2888  cavern from vim and parse error output, and run aven from vim.  Tweak the
2889  existing vim mode for .svx files to fix a few minor bugs and add support for
2890  the new "*data passage" style.
2891
2892* aven: fix drawing of the "blob" end of the measuring line on graphics cards
2893  which can't draw large enough blobs for us.
2894
2895* aven: sort out confusion about what encoding everything is in which means
2896  that the distance measured by the measuring line actually gets displayed
2897  and also fixes problems with empty menu items in non-English locales in
2898  some cases.
2899
2900* aven: redraw grey background after a menu is closed over the aven window
2901  with no survey loaded.
2902
2903* aven: fix bug which caused printing to crash (introduced in 1.1.8).
2904
2905* aven: avoid crash on some machines when opening "About" dialog before having
2906  loaded a survey.
2907
2908* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
2909
2910* (Unix version): aven: Fix character set handling of cavern output.
2911
2912* cavern: Report an error if a cross-section is specified for a station which
2913  doesn't exist.
2914
2915* Updated French and Italian translations.
2916
2917* (Unix version): aven: Fix "Can't open message file `en_US' using path
2918  `${prefix}/share/survex'" error.
2919
2920* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
2921  (doesn't affect Survex itself, but other applications which use img.c should
2922  update their copy).
2923
2924* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
2925  and later are caught by configure, whereas older wx versions are caught when
2926  trying to compile).
2927
2928Changes in 1.1.8 (2006.06.30):
2929
2930* Drop support for building with wxWidgets versions prior to 2.4.0
2931  (which was released on 2003-01-07).
2932
2933* aven: Printing through aven now uses settings from the "[aven]" section
2934  of print.ini, and support for hierarchical sections (using "like=")
2935  has been disabled.
2936
2937* aven: Change mouse actions to be compatible with those in Survex 1.0.
2938  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
2939  left drag is now smart about not rotating and zooming at the same
2940  time.
2941
2942* aven: Highlighting stations now happens as you type, and pressing
2943  "Enter" or clicking the "Find" button now pans and zooms to show the
2944  highlighted stations.
2945
2946* aven: Left-clicking away from a station now cancels measuring line.
2947
2948* aven: Setting view to North, South, East, or West is now animated like
2949  the tilt from plan to elevation.
2950
2951* aven: Fix presentation saving to also write "." for decimal points and
2952  presentation loading to accept either "." or ",".
2953
2954* (Unix version): aven: Add text for all toolbar items so that aven
2955  will work with the Gnome desktop preference for displaying toolbars as
2956  icons with text or just text (wxWidgets needs fixing first though).
2957
2958* (Unix version): aven: Remove the ability to detach the menu bar (yell
2959  if you actually used it and I'll restore it!)
2960
2961* aven: Add "all survey files" option to the "open file" dialog.
2962
2963* (MS Windows version): aven: Fix cursor keys to pan survey.
2964
2965* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
2966
2967* (MS Windows version): Fix installer to work on Windows 2000 or XP if
2968  run by an unprivileged user.
2969
2970* (MS Windows version): Upgrade to the latest version of InnoSetup (the
2971  installer builder we use) and include new installer translations for
2972  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
2973
2974* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
2975  translations of messages for wxWidgets (the GUI library we use).
2976
2977* aven: Disable "Highlight exported points" if there aren't any.
2978
2979* Updates to French translation from Michel Bovey.  Also updates to German,
2980  Italian, Catalan, Spanish, and Romanian translations.
2981
2982* (Unix version): test suite: fix smoke test to pass even without X running
2983  (it was meant to but the code had a bug).
2984
2985* aven: Check if OpenGL is available and exit cleanly with a helpful error
2986  if it isn't.
2987
2988* (Unix version): aven: Fix --help and --version to work without a working
2989  X display (provided it's built with wxWidgets 2.5.1 or newer).
2990
2991* aven: Automatically select the presentation tab of the notebook when the user
2992  selects "New Presentation" or "Open Presentation".
2993
2994* aven: Fix "Delete" in the presentation list to not get passed on (and so not
2995  reset to default view as well).
2996
2997* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
2998  empty.
2999
3000* aven: Fix Cursor Up and Down in the presentation list to move the highlight
3001  up and down instead of being passed on and moving the survey.
3002
3003* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
3004  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
3005  Safari 2.0.3, and InkScape 0.42.
3006
3007* aven: Put a 5mm border around exported SVG files to allow for station markers
3008  and non-zero width lines.
3009
3010* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
3011  was turned on.
3012
3013* aven: Actually close the file we're exporting which fixes problems with it
3014  not always being fully written.
3015
3016Changes in 1.1.7 (2005.10.18):
3017
3018* cavern: Add validity checking for dates in *date commands (with feature
3019  test in testsuite).  A date entered as just "year" or "year.month" now
3020  becomes a date range for the relevant period (previously it became a single
3021  date near the middle of that period).
3022
3023* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
3024  with MS Windows).
3025
3026* extend: Default output name for a file called input.3d is now input_extend.3d
3027  rather than just extend.3d (which was annoying if you wanted to extend
3028  several surveys in the same directory).
3029
3030* aven: OpenGL 2.0 always includes support for point sprites so rework
3031  our check for them to include that knowledge.
3032
3033* aven: Regenerate depth bar if user switches to/from metric units.
3034
3035* aven: Don't clear the "there" mark just because the mouse pointer has
3036  moved off a station.
3037
3038* aven: When processing a .svx file, put the resultant .3d file in the
3039  same directory (since that's where we then try to load it from).
3040
3041* aven: Fix labelling of date colouring on 32 bit platforms.
3042
3043* aven: If "colour by date" is on and we load a survey with no date info
3044  (or all surveyed on the same date) then set "colour by none".
3045
3046* aven: Make the error dialog modal and remove a signal handler once it
3047  has fired to prevent endless (or seemingly endless) cascades of error
3048  dialogs.
3049
3050* aven: Enforce a minimum object volume diameter of 1m to avoid problems
3051  if a survey file with only one station in is loaded.
3052
3053* aven: Fix problems with indicators disappearing when we're drawing
3054  blobs and/or crosses the slow (but always supported) way.  (Problem
3055  introduced in 1.1.6).
3056
3057* (Unix version): aven: Really stop setting extra toolbar margin when using
3058  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3059  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3060
3061* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3062  we've been compiled with, and which GTK+/Motif version where appropriate.
3063
3064* (Unix version): Fixed build on Fedora Core 3.
3065
3066* documentation: Updates to 3d file format specification from Mike McCombe.
3067
3068Changes in 1.1.6 (2005.10.10):
3069
3070* (MS Windows version): Distribution is about a third smaller than 1.1.5
3071  (mostly because mingwm10.dll is no longer required).
3072
3073* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3074  it, showing cavern's output in a window (with errors and warnings clickable
3075  to load the offending file into an editor), and then loading the resulting
3076  3d file.
3077
3078* aven: Added "Colour by Date" option.
3079
3080* aven: Disable "Colour by Depth" option if there's no elevation variation.
3081
3082* aven: Don't crash if trying to load a survey with no elevation variation.
3083  Instead turn off depth colouring.
3084
3085* aven: Export as HPGL added.
3086
3087* aven: Improved update of mouse coordinates and measuring line (thanks to
3088  Martin Green).
3089
3090* aven: Show the coordinates of either the mouse pointer or the nearest
3091  survey station to it (if there is one near enough).  Showing both was
3092  confusing and meant the status bar overflowed on smaller displays.
3093
3094* aven: When printing an extended elevation, don't show bearing and elevation.
3095
3096* aven: Don't lock "flat" surveys which aren't extended elevations - a
3097  flat survey with LRUD data isn't flat any more!
3098
3099* aven: When we have to draw blobs and crosses the slow way (because the
3100  graphics hardware doesn't support the fast way), draw them so that they
3101  should appear at the correct depth into the 3D scene instead of on top
3102  of everything else.
3103
3104* aven: Make "play presentation backwards" icon green to match the other
3105  presentation icons.
3106
3107* (MS Windows version): aven: Mouse clicks on the survey view now set the
3108  keyboard focus there.
3109
3110* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3111
3112* (MS Windows version): aven: Fix redrawing of measuring line.
3113
3114* cavern: Store dates for img_XSECT.
3115
3116* cavern: Fixed small one-off memory leak if you specify -o more than once.
3117
3118* (Unix version): Check environmental variable LC_MESSAGES when deciding what
3119  language to use for messages.
3120
3121* (MS Windows version): "Print" on a 3d file now prints through aven rather
3122  than the separate printer driver (Unix has done this for some time).
3123
3124* Removed old printer drivers.
3125
3126* img library: When creating a 3d file, ignore img_XSECT if we've been asked
3127  to write a file format version which doesn't support it.
3128
3129Changes in 1.1.5 (2005.09.20):
3130
3131* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3132
3133* aven: Make blobs round like they are in Survex 1.0.
3134
3135* aven: If the graphics drivers don't support drawing blobs using OpenGL
3136  point markers, fall back to drawing filled circles.
3137
3138* aven: If the graphics drivers support it, draw crosses as texture mapped
3139  OpenGL point markers which is much faster.
3140
3141* aven: Cross size increased to match Survex 1.0.
3142
3143* aven: We must update which blobs are displayed if display of surface or
3144  underground legs is toggled.
3145
3146* cavern: Fix handling of a *solve followed by survey data, none of which is
3147  attached to the previous data.
3148
3149* cavern: Fixed "No survey data" error when a *solve is followed by another
3150  *solve (or the implicit solve at the end of processing) with no data between
3151  them.
3152
3153Changes in 1.1.4 (2005.09.19):
3154
3155* aven: Added Aven's icon to the "About" dialog.
3156
3157* aven: Use localised character for the decimal point (e.g. "," in most
3158  continental European countries).
3159
3160* aven: Previously the survey tree would get focus and then take keypresses
3161  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
3162  operate on the cave, and transfer the input focus across when we do.
3163
3164* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3165
3166* aven: Speed up intialisation by delaying creation of OpenGL lists until
3167  they're needed.
3168
3169* aven: Added Mark Shinwell's bounding box with shadow of the survey.
3170
3171* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3172
3173* aven: Reworded "Restore Default Settings" as "Restore Default View".
3174
3175* (Unix version): aven: Set sensible default margins for printing and preserve
3176  any margin values the user specifies between runs (previously margins
3177  defaulted to 0 each time aven was run).
3178
3179* Documentation: Document *DATA PASSAGE in the manual.
3180
3181Changes in 1.1.3 (2005.09.07):
3182
3183* (Microsoft Windows version): Fixed build problems.
3184
3185* cavern: Allow OMIT character (-) for left/right/up/down.
3186
3187* aven: Remove an unnecessary menu separator.
3188
3189* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3190
3191* aven: Make the tooltip for "Hide" show the number of found stations.
3192
3193* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3194
3195* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3196  when there's a presentation loaded.
3197
3198* aven: Make entrances green in side panel tree list to match green blobs used
3199  in cave view.
3200
3201* aven: Don't show surface labels if we're not showing surface data, etc.
3202
3203* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3204  make "Space" the key for this.  Keep Return working "Stop Rotation" so
3205  existing users are happy, but don't advertise it.
3206
3207* aven: Normalise filename by adding any extension used, and use the normalised
3208  filename for file history and window title.
3209
3210* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3211  as the toolbar buttons already have a sensible margin - the extra margin is
3212  only needed with GTK1.2.
3213
3214* aven: Fix handling of plumb legs in tube model.
3215
3216* aven: Fixed swapped L and R in tube model.
3217
3218* extend: Preserve UD cross-section information in extended elevation.
3219
3220* extend: Add new messages for John Pybus' enhancements.
3221
3222Changes in 1.1.2 (never formally released):
3223
3224* Added support for LRUD data in .svx files, in .3d files, and aven can
3225  now load and display it on screen and on printouts.  The ability to "fake"
3226  LRUD data in aven is gone for now but will reappear in some form later.
3227
3228* cavern: Removed support for writing Chasm's 3dx format.  We're going to
3229  fold any desirable missing chasm functionality into aven.
3230
3231* aven: Rearranged mouse actions as discussed on the mailing list.  Added
3232  cursors for each different mouse action to help the user learn what each
3233  does.  Also added cursors for the "compass" and "clino" as well as the
3234  scalebar to suggest to the user that they can be dragged to change the view.
3235
3236* (Unix version): aven: Don't segfault if LANG isn't a known language.
3237
3238* tests/smoketest.tst: If X windows is running, check that we can run aven
3239  with --help and --version.
3240
3241* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3242  no results are listed for it.  This revealed that there was a "newline" test
3243  which should have been called "badnewline", and was a broken testcase too!
3244  Fixed all these problems.
3245
3246* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3247  and omitted forward compass/clino readings in Compass DAT files.  Added
3248  a feature test for this to the testsuite.
3249
3250* It no longer makes sense to have an option not to build aven or to build aven
3251  without OpenGL so remove old machinery for this from configure and the
3252  sources.
3253
3254* (Unix version): configure: Check if "-lXxf86vm" is needed.
3255
3256* configure: Better output for strcasecmp test.
3257
3258* aven: Fix crosses to work much better.  Not a total fix - their position
3259  in the Z buffer isn't correct and they're rather slow to plot.
3260
3261* aven: Don't regenerate the hittest grid every time the mouse moves while
3262  animating, which solves the mysterious pausing effect (thanks go to Martin
3263  Green for spotting this!)  Also clear all the status bar coordinates when
3264  animating.
3265
3266* aven: Sort out clashing menu shortcuts in some languages.
3267
3268* aven: Fixed compilation problem on x86_64
3269
3270* SPUD: Pruned out stuff which has been done or which is not actually relevant
3271  to this branch.
3272
3273* Merge various changes from 1.0 branch:
3274
3275  + aven: Port over "printing from aven" functionality.
3276
3277  + aven: Port over "export as" functionality,
3278
3279  + Add David Loeffler's vim mode for .svx files.
3280
3281* aven: Fix check for whether a label is behind us in perspective view.
3282
3283* aven: Don't use an opengl list for drawing the indicators - we typically make
3284  a new list each time we plot them anyway.
3285
3286* Remove lingering traces of support for RISC OS and pre-386 MSDOS
3287
3288* aven: Set icon on non-Windows platforms too.  This means that with
3289  WindowMaker on Unix you get an icon on the AppIcon by default.
3290
3291* configure: Update wxWindows checks to handle newer wx versions.
3292
3293* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3294  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
3295  for anyone building from CVS).
3296
3297* acinclude.m4: Quote macro name for fix autotools warning.
3298
3299* Documentation: "tilt up" is "'" not ",".
3300
3301* aven: Add support for mousewheels (to tilt the cave).
3302
3303* aven: Fixed twisted transitions to and from pitches in certain cases.
3304
3305* aven: Pick a sensible initial window size when the user's desktop is spread
3306  over more than one monitor (works best with wx2.5 or newer, but try to do
3307  better with wx2.4 or earlier as well).
3308
3309* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3310  contents being visible before any survey is loaded.
3311
3312* aven: Allow a coloured texture to be used
3313
3314* aven: Don't initialise until we have data (to the user, this means the window
3315  is default colour (grey for most systems) not black until a survey is
3316  loaded).
3317
3318* aven: Fixed weird "shadowed" icons.
3319
3320Changes in 1.1.1 (2004-10-06):
3321
3322* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
3323  startup.
3324
3325* aven: Delay loading the bitmap for the "About" dialog until it is first
3326  needed.  We want start up to be as quick as possible.
3327
3328Changes between 1.0.32 and 1.1.0 (never formally released):
3329
3330* NOTE: Survex 1.1.X releases are development snapshots made available for
3331  the purposes of allowing wider testing and getting more user feedback.  Once
3332  the code has stabilised the version number will be raised to 1.2.0.
3333
3334* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3335  you're using Windows 95 - these can be obtained from:
3336  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
3337
3338* aven: Solid passages - passage dimensions are currently inferred from
3339  the leg length (pretty effective as you can measure longer legs in
3340  larger passages).  Use of real LRUD data coming soon...
3341
3342* aven: Depth colouring is now continuously varying.
3343
3344* aven: Colour by depth can now be turned off (and there's the start of a
3345  framework for properly implementing colour by date, error, etc).
3346
3347* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3348  match (? matches any character, * matches any number of characters).
3349
3350* aven: We now use the status bar for coordinates, distances, etc to make
3351  better use of screen space.
3352
3353* aven: Full screen mode (F11).
3354
3355* aven: Perspective view.
3356
3357* aven: Context sensitive cursor shape - needs more work.
3358
3359* aven: Mouse actions changed (hopefully they're now more natural, but
3360  you may find the change disorientating - feedback wanted on this).
3361
3362* aven: Added "presentations" which allow you to set up fly-through paths
3363  and load/save/run them.
3364
3365* aven: A presentation can be exported as a movie file.
3366
3367* aven: Added Save screenshot facility.
3368
3369* aven: Depth fogging option.
3370
3371* aven: Added Smooth Lines option.
3372
3373* aven: Added Textured Walls option.
3374
3375* aven: If a survey has surface legs but no underground legs, default to
3376  showing the surface legs.
3377
3378* cavern: Dates given to *date are now stored in the 3d file.
Note: See TracBrowser for help on using the repository browser.
