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