5        * src/guicontrol.cc,src/mainfrm.cc: On OS X, F11 is used by the desktop
6          so change the menu shortcut for "Full Screen Mode" to be the OS X
7          standard shortcut Shift-Command-F.

10Mon Oct 15 02:28:46 GMT 2012  Olly Betts <olly@survex.com>
11        * src/Makefile.am: Remove workaround for GCC 2.95 failing to compile
12          gfxcore.cc - GCC 2.95 is obsolete now.

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