1Changes in 1.2.3 (2011-12-31):
2
3* Fix to build with wxWidgets 2.9.2.
4
5* (Mac OS X version):
6
7  + Processing .svx files from aven now works.
8
9  + Remove spurious blank lines from the licence text in "Get Info".
10
11  + Don't create the help menu at all, as it is empty (because the "About"
12    entry goes elsewhere) and sometimes seems to appear in the UI.
13
14  + INSTALL.OSX: Update to reflect current status.
15
16* aven:
17
18  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
19
20  + Improvements to text plotted on the survey pane:
21
22    - Support plotting Unicode character points > 256 by lazily loading the
23      data for them from the font file and plotting them with a direct call to
24      glBitmap(), which is slower but doesn't require a display list per
25      character.
26
27    - Adjust the spacing from fixed width to putting a one pixel gap either
28      side of each one character (so two between adjacent glyphs).  Mostly this
29      reduces the horizontal width, but it adds a pixel for characters like "m"
30      and two in a few cases.
31
32    - Fix .pixelfont file generation to correctly handle characters wider than
33      8 pixels.
34
35  + Fix expected cross shape so don't always reject using texture mapping to
36    draw crosses.
37
38  + Make the green colour used for entrances in the survey tree the same
39    (slightly darker than before) green used for the entrance blobs.
40
41  + Report the version of the library we're actually running with if built
42    against wx >= 2.9.2.  Make it clear that the version reported is the
43    version *built* with for wx < 2.9.2.
44
45* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
46  messages.
47
48* Transliterate curly double quotes to ASCII straight double quotes if we can't
49  represent them in the current character set.
50
51* Translation updates for French and Slovak.
52
53* Test suite:
54
55  + Add test coverage for interleaved diving data.
56
57  + Add testcase for diving data with topofil-style distance.
58
59Changes in 1.2.2 (2011-10-06):
60
61* aven:
62
63  + Replace the textured-mapped font drawing with an approach based on
64    glBitmap.  This doesn't suffer from the character alignment issues which
65    the textured-mapped fonts had, and is actually significantly faster on some
66    machines.  The current font used is (mostly) fixed-width, but this isn't an
67    inherent limitation - it was just the easiest font data to convert to a
68    usable format.
69
70  + Fix assertion failure due to rounding differences on loading certain .3d
71    files.  (ticket#26)
72
73  + Fix assertion failure when turning on 3D passages if they stick out higher
74    or lower than any station.  (ticket#29)
75
76  + Fix grid not to disappear when blobs are turned on and blobs are drawn
77    using lines.
78
79  + If a degree sign isn't available in the character set in use, transliterate
80    it to 'dg' rather than skipping it.
81
82  + Fix message which should have been a degree sign but got lost in the format
83    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
84    that bearings in the status bar now have a degree sign after them if they
85    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
86
87  + Fix print dialog to calculate the scale required for "One page" right
88    before it calculates how many pages are required, so we don't end up
89    something other than 1x1 being shown when the user changes settings.
90
91  + Update the calculations for picking a scale and for deciding how many
92    pages are needed to take into account the change in info box height made
93    in 1.2.1.
94
95Changes in 1.2.1 (2011-10-04):
96
97* Translation updates for US English.
98
99* aven:
100
101  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
102    it now shows colours for dates and errors as well as depths.
103
104  + In the colour key for "colour by date", change "No info" to "Undated".
105
106  + Remove the dark grey background from the colour key and just put a single
107    pixel black border around the colours.  This is more in keeping with the
108    other controls, and means the colours are now on a black background so more
109    visually similar to the survey legs.
110
111  + Move the colour key's "Undated"/"Not in loop" entry down a little to
112    improve the appearance.  Make each section a pixel taller.
113
114  + Allow "Colour by X" to be selected even if there's no data for X or only a
115    single value of X used (the colour key is much smaller in these cases, and
116    does still provide some useful information).
117
118  + Fix incorrect calculation of depth colouring for survey legs which straddle
119    a depth band boundary.
120
121  + The scale bar, compass, clino, and colour key now all have right click
122    menus which allow related actions to be performed (especially handy in
123    full-screen mode).
124
125  + Improve the font used on the survey pane - it now contains the '-'
126    character (so the clino now shows negative angles as negative, and dates
127    in the colour key are now hyphenated).  Also the spacing and alignment
128    are a little better, though still not perfect.
129
130  + PLT file export now handles spaces and control characters in station names
131    by escaping them with '%' as in URLs.
132
133  + Pressing "Enter" on a station in the tree control now centres the view on
134    that station.
135
136  + The scale bar is now cached in an OpenGL display list since it often gets
137    redrawn exactly the same - for example, when rotating, panning, etc.
138
139  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
140    then forces a refresh of the survey pane.  This is intended as a debugging
141    aid - if pressing F5 changes the display at all then there's a missing case
142    where a list should have been invalidated (please report if you find such
143    a case as it is a bug).
144
145  + We now automatically track which OpenGL display lists need to be
146    invalidated on window width or height changes.
147
148  + Increase scale bar maximum width from 65% of the window width to 75% as it
149    was in 1.0.x (except that if that would overlap the clino we now reduce
150    that proportion down until it reaches 50%).  Make the limit of zooming in
151    the same as in 1.0.x.  (ticket#23)
152
153  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
154    the application was fullscreen (the dialog got opened under the main
155    window!)  To work around this, aven would switch out of full screen mode
156    temporarily while showing a dialog.  This case works properly with recent
157    wxGTK, so disable our workaround with versions we know work.  Also, apply
158    the workaround only for wxGTK, not everywhere except on Microsoft Windows
159    as there's no reason to think we need it for other platforms.
160
161  + Grey out the "View North" action when we're already viewing North, and
162    similarly for other compass points.
163
164  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
165    info in the "About" dialog.
166
167  + Fix to set the correct filename on the root of the survey tree - previously
168    the filename of the previous file loaded was used!
169
170  + The movie export code now works with newer versions of the FFmpeg libraries
171    as well as still working with older versions.
172
173  + Fix mixed up messages - the print dialog now says "View" on the left
174    subgroup of controls rather than some unrelated message.
175
176  + On printouts, combine the "Plan View"/"Elevation" info box field with the
177    field which gives the bearing and reduce the height on the info box by the
178    removed field, so it's now 3cm for plans and elevations, as for extended
179    elevations.  Report the tilt angle for tilted elevations which it seems has
180    been missing for ages (it's not in recent 1.0.x either).
181
182  + Tweak the exact positioning of informational text on printouts to look
183    nicer and make better use of the available space.
184
185  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
186    dialog.
187
188  + Make the sign of the tilt angle for printouts consistent with the sign
189    shown by the "clino" in the survey pane.
190
191  + In the "Print" dialog, when in plan view disable the "Plan view" button,
192    and similarly for the "Elevation" button.
193
194  + (Microsoft Windows version): Sort out appearance of custom cursors.
195
196  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
197
198  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
199    you can't get out again easily, so add code to explicitly check for F11
200    being pressed and toggle full screen.
201
202* (Linux version): Fix the RPM .spec file for where man pages now get installed
203  and package aven.svg and the vim support files.  (Fixes from James Begley)
204
205* "make check" now performs several checks on the translation files.
206
207* More messages are now available to be translated.
208
209* cavern: Fix reporting of ranges of survey coordinates, which was broken by
210  the message handling changes in 1.2.0.
211
212* Fix warning when compiling with GCC.
213
214* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
215  sudo for installing on Unix.
216
217* In the manual, replace the instructions for building from source with a
218  pointer to the clearer instructions in INSTALL.
219
220* In the manual, make it clear that installing with administrator rights
221  also applies to newer platforms than XP.
222
223* doc/TODO.htm: Update.
224
225Changes in 1.2.0 (2011-09-20):
226
227* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
228  English.
229
230* tests/smoke.tst: aven no longer requires an X display for --help or
231  --version, so replace skip of this check with a check that this remains the
232  case.
233
234* We now use the standard .po and .pot file formats for storing translations
235  (rather than the Survex-specific messages.txt format), and then translate
236  these into Survex's .msg format.
237
238* (Unix version): Move survex man page to section 7 (since it isn't documenting
239  an actual command).
240
241* (Unix version): Write each generated man page to a temporary file, then
242  atomically rename, to avoid leaving an empty or partial man page behind if
243  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
244  recurrence of that).
245
246* (Unix version): Default to installing docs into /usr/share/doc/survex rather
247  than /usr/doc/survex.
248
249* aven:
250
251  + Fix handling of accented characters in the survey pane.
252
253  + Aven icon redrawn in SVG format - it's now a vector image which looks
254    nicer at larger sizes.
255
256  + Explicitly request double-buffering, which seems to be needed for systems
257    with GLX >= 1.3.
258
259  + Fix crash while trying to load certain .3d files.
260
261  + Movie export code updated to work with more recent versions of FFmpeg.
262    Currently this is disabled in Microsoft Windows builds, pending getting the
263    required libraries set up for building releases.
264
265  + Reporting of errors during movie export improved.
266
267  + Force playback speed to "x1" during movie export.
268
269  + Use stock IDs for buttons where appropriate - such buttons may now be
270    rendered with icons on some platforms.
271
272  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
273    ISO8859-1).
274
275  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
276    as it's no longer required with modern versions.
277
278  + Don't redraw the survey on every mouse movement in the survey pane unless
279    the measuring line is (or just was) active.  (ticket #17)
280
281* cavern:
282
283  + Drop "non-fatal" from the report of how many errors there were at the end
284    of the run - it just confuses users - we won't even get here if there's a
285    fatal error!
286
287  + Add --3d-version option to allow the user to specify the version of the 3d
288    format to output.  (ticket#21)
289
290* img library:
291
292  + Make the highest and lowest valid values for img_output_version available
293    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
294
295* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
296  volume actually gets mounted.  Fix URL for downloading wxWidgets.
297
298Changes in 1.1.16 (2011-05-16):
299
300* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
301  Portuguese, and US English.
302
303* Use horizontal ellipses character rather than '...' and right arrow character
304  rather than '->' where these characters are available.
305
306* (Unix version): Link with -lGL, if it exists, to support linking with gold or
307  GNU ld --as-needed (Debian bug #615781).
308
309* img.c:
310
311  + Fix code typo for IMG_API_VERSION == 0 case.
312
313  + Fix code typo in code used when IMG_HOSTED isn't defined.
314
315* doc/TODO.htm: Remove entries which have now been done.
316
317* (Microsoft Windows version): aven: We now include all the available
318  translations for messages from wxWidgets, which means that standard widgets
319  will appear translated where available even if Survex messages aren't
320  translated.
321
322Changes in 1.1.15 (2010-10-15):
323
324* aven:
325
326  + In the cavern log window, change the "Rerun" button to "Reprocess" to
327    follow terminology in manual and elsewhere.  Fixes ticket#15.
328
329  + When displaying output from cavern, don't update the window after every
330    line, but only when we don't have data from cavern pending.  Hopefully
331    addresses ticket#12.
332
333  + If we aren't using GL_POINTS for blobs, draw them using a series of
334    abutting lines rather than with gluDisk which is faster and gives a
335    consistent shape.
336
337  + Check whether blobs and crosses actually render correctly as points/point
338    sprites, and if they don't, fall back to drawing them with lines.  The
339    best method is cached on disk, and rechecked automatically if the graphics
340    hardware is changed or the drivers upgraded.
341
342  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
343    though, so we still enable USE_FNT by default).
344
345  + Don't offer "All files" wildcard in presentation save dialog.
346
347  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
348    more places.
349
350  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
351    when running cavern from aven.  Fixes ticket#11.
352
353* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
354
355* diffpos: Handle files with duplicate labels in better - extend generates
356  duplicate labels when it breaks a loop.
357
358* Enable eswap-break testcase now that diffpos handles duplicate station names.
359
360* New v7 of .3d format which stores survey dates as number of days since
361  January 1st 1900, so we now support dates from 1900-2078 (rather than
362  1970-2037) with a smaller file size.  The img API is now versioned - you
363  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
364  gives the survey dates in days in days1 and days2 instead of as time_t
365  values in date1 and date2.  Fixes ticket#14.
366
367* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
368  former has been the canonical name for some time, with www.survex.com just
369  redirecting to it.
370
371* (Unix version): Use unlocked file I/O if available, which can be much faster
372  in some cases (we don't need the locking as we don't do multithreaded file
373  I/O).
374
375* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
376  headers.
377
378* (Mac version): buildmacosx.sh now works again.
379
380* Most tests weren't actually running any testcases (looks like a sh
381  portability issue).  This is now fixed, and fortunately all tests still pass.
382
383* Include the extra .isl translation files for Innosetup in the source archive.
384
385Changes in 1.1.14 (2010-07-26):
386
387* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
388
389* aven:
390
391  + After processing survey data, if there were warnings or errors, add a
392    "Rerun" button to allow easy reprocessing after fixing problems.  If there
393    were only warnings, also add an "OK" button to allow moving on to viewing
394    the processed survey data (fixes ticket#13).
395
396  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
397
398  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
399    not the ': ' after), and to make the title for the terminal the
400    warning/error message.  Avoid false positives by checking that '<line>' is
401    a number.
402
403  + Don't double escape the contents of href and target in links in the cavern
404    log window.
405
406  + Improve handling of the splitter window, fixing behavioural glitches in
407    various cases.
408
409  + Highlight stations matching any current search when a file is loaded.
410    (ticket#9)
411
412  + (Mac version): Fix build issue due to Mac OS X polluting the global
413    namespace with its own "Point" class.
414
415  + (Unix version): The Gnome print dialog has its own preview window so
416    suppress ours if using the Gnome one.
417
418  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
419
420  + (Microsoft Windows version): Fix handling of a double-click on the survey
421    tree when built with wxWidgets >= 2.8.11.
422
423* cavern: Report relevant file and line number for three warnings which didn't
424  give them before.
425
426* (Unix and Mac versions): configure: Update the wx-config probing code -
427  wxmac-config etc aren't present with newer wxWidgets versions so there's no
428  point looking for them now.
429
430* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
431  for easy installation.  Update it to work with the latest Survex versions
432  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
433  private wxWidgets, use 2.8.11 not 2.7.0-1).
434
435* manual:
436
437  + Correctly capitalise "GTK".
438
439  + Note that on Linux we only regularly test builds with the GTK+ version
440    (change taken from 1.0).
441
442* Fixed the cad3d man page, which was an empty file in 1.1.13.
443
444Changes in 1.1.13 (2010-06-16):
445
446* Say "wxWidgets" instead of "wxWindows" consistently.
447
448* img.c: Fix small memory leak (filename_opened member).
449
450* cad3d, aven: Fix export to SVG when a label contains a '%' character.
451
452* aven:
453
454  + wxWidgets 2.6.0 or newer is now required.
455
456  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
457    work but hasn't been tested recently (all packaged versions of wxWidgets
458    seem to be Unicode now).
459
460  + Fix potential uses of uninitialised variables which may have been causing
461    occasional glitches when loading a file on start-up.
462
463  + Improvements to the handling of the font used for plotting labels and other
464    text on the survey pane:
465
466    - Loading the font file is more efficient.
467
468    - Character spacing is improved.
469
470    - Default font is now anti-aliased.
471
472  + "About" dialog:
473
474    - Add "Copy" button to copy the system info to the clipboard for easier
475      bug reporting.
476
477    - List OpenGL extensions last, since there are usually lots of them with a
478      modern gfx card.
479
480    - Fix 100% CPU usage while the "About" dialog is open.
481
482  + Processing .svx files:
483
484    - Passing a .svx file on the command line now works better.
485
486    - Put the survey data log window in a splitter in the usual frame rather
487      than opening a separate frame for it.
488
489    - Auto-scroll the log window until we've reported a warning or error.
490
491    - Fix small memory leak.
492
493  + The presentation filename now defaults to using the basename of the
494    currently loaded dataset, but we always prompt before we first save with
495    such a name.
496
497  + Reduce memory usage when saving a screenshot.
498
499  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
500    persist the window size (and maximised or fullscreen state) between
501    invocations.
502
503  + Fix reporting of OpenGL errors.
504
505  + Fix glitches when tilting while looking East.
506
507  + Added Portuguese and Slovak translations of wxWidgets messages.
508
509* Documentation:
510
511  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
512
513  + Drop the "alternative manual formats" self-extracting zip file - people
514    will generally just want one of the formats, so downloading several
515    together isn't very useful.
516
517  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
518
519  + GPL.htm: Replace HTML version of licence with a link to the version on
520    the FSF website.
521
522  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
523    low level to be of interest to non-developers, and developers can look at
524    the source code.
525
526* (Unix version): configure: New preferred name for specifying wx-config script
527  is WX_CONFIG.  WXCONFIG still supported for compatibility.
528
529* (Linux version): Source RPM package dropped as you can just build an RPM
530  package from the source tarball.
531
532* (Microsoft Windows version): The installer is now created with a newer
533  version of InnoSetup, which gives a 10% smaller download.
534
535Changes in 1.1.12 (2007-02-07):
536
537* aven:
538
539  + Remember the window size or maximised/fullscreen state between invocations.
540
541  + Add options dialog to "Export" similar to the one for "Print".
542
543  + The "number of pages required" in the print dialog now updates when you
544    change what is to be shown (underground legs/surface legs/station
545    names/crosses).
546
547Changes in 1.1.11 (2006-11-25):
548
549* Updated Czech, Spanish, and Slovak translations.
550
551* (MacOS X version): Assorted OS X specific tweaks and fixes.
552
553* aven:
554
555  + Pick a smaller and clearer font for labels.
556
557  + Fix character spacing.
558
559  + Tweak display of bearing and elevation angles to look nicer with
560    proportional fonts.
561
562  + Use the title from the 3d (or plt, etc) file for the window title
563    rather than the filename.
564
565  + Show distances to 2 decimal places rather than the nearest integer.
566
567  + Only consider underground legs when calculating the depth bands and
568    depth colouring.
569
570  + Add "Colour by Error".
571
572  + Add entry for "white" in date and error keys.
573
574  + When setting the view to a single point, don't change the scale.
575
576  + If reloading the same file, don't change the view
577
578  + Fix filetypes selector in open dialog.
579
580  + Fix the charset we use for aven in certain cases.
581
582  + Call msg_init before using msg_lang or it won't ever be set!
583
584  + Pass wx the full language code to initialise the C library locale.
585
586  + Fix bug in generating prefix tree view which could lead to a bogus
587    leading dot on some survey names (bug probably introduced in 1.1.10).
588
589  + "New Presentation" now ensures that the side panel is open
590
591  + Fix updating of cached opengl lists when the view is reset to the
592    default.
593
594* Ignore LANG if it starts with a digit to avoid problems with bogus value for
595  LANG which AutoCAD installation seems to set on MS Windows.
596
597* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
598  specified.  Either/both can be set to ":".
599
600* dump3d: Report unknown (to dump3d) codes returned by img.
601
602* img library: Flag all stations as underground in the old "ASCII" .3d format.
603
604Changes in 1.1.10 (2006-07-14):
605
606* aven: Clicking on a survey name in the survey tree now highlights it in
607  the map view.  Double-clicking zooms the view to show the clicked survey
608  highlighted.  Clicking the root clears the highlighting and double-clicking
609  the root restores the default view.  To expand/collapse a branch, click
610  on the "[+]" or "[-]" icon to the left of the survey name.
611
612* aven: The measuring line can now measure to anywhere in plan or elevation
613  view (not just to a station!)  In plan view the horizontal distance and
614  bearing are shown, while in elevation view the vertical distance is shown.
615
616* aven: Moving the mouse over a station in the survey view now highlights
617  that station in the survey tree (though it may not be visible if the
618  survey(s) it is in aren't expanded).
619
620* aven: Clicking on a station to centre the view now moves the mouse pointer
621  to the new location of the station (except on Mac OS X where this isn't
622  allowed).
623
624* aven: Fix which presentation toolbar buttons are shown as depressed.
625
626* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
627
628* vim files are now installed with the correct paths (bug introduced in 1.1.9).
629
630Changes in 1.1.9 (2006-07-04):
631
632* (Unix version): Install desktop files for aven and svxedit contributed to the
633  Ubuntu package by Phil Bull, and corresponding pixmaps.
634
635* Fix img to filter out cross-sections which don't match the subsurvey (if
636  specified).  The API now returns img_XSECT_END to mark the end of a
637  passage rather than setting a flag on the last img_XSECT of the passage.
638
639* Enhance integration with the vim editor - this can now colour .err files, run
640  cavern from vim and parse error output, and run aven from vim.  Tweak the
641  existing vim mode for .svx files to fix a few minor bugs and add support for
642  the new "*data passage" style.
643
644* aven: fix drawing of the "blob" end of the measuring line on graphics cards
645  which can't draw large enough blobs for us.
646
647* aven: sort out confusion about what encoding everything is in which means
648  that the distance measured by the measuring line actually gets displayed
649  and also fixes problems with empty menu items in non-English locales in
650  some cases.
651
652* aven: redraw grey background after a menu is closed over the aven window
653  with no survey loaded.
654
655* aven: fix bug which caused printing to crash (introduced in 1.1.8).
656
657* aven: avoid crash on some machines when opening "About" dialog before having
658  loaded a survey.
659
660* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
661
662* (Unix version): aven: Fix character set handling of cavern output.
663
664* cavern: Report an error if a cross-section is specified for a station which
665  doesn't exist.
666
667* Updated French and Italian translations.
668
669* (Unix version): aven: Fix "Can't open message file `en_US' using path
670  `${prefix}/share/survex'" error.
671
672* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
673  (doesn't affect Survex itself, but other applications which use img.c should
674  update their copy).
675
676* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
677  and later are caught by configure, whereas older wx versions are caught when
678  trying to compile).
679
680Changes in 1.1.8 (2006.06.30):
681
682* Drop support for building with wxWidgets versions prior to 2.4.0
683  (which was released on 2003-01-07).
684
685* aven: Printing through aven now uses settings from the "[aven]" section
686  of print.ini, and support for hierarchical sections (using "like=")
687  has been disabled.
688
689* aven: Change mouse actions to be compatible with those in Survex 1.0.
690  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
691  left drag is now smart about not rotating and zooming at the same
692  time.
693
694* aven: Highlighting stations now happens as you type, and pressing
695  "Enter" or clicking the "Find" button now pans and zooms to show the
696  highlighted stations.
697
698* aven: Left-clicking away from a station now cancels measuring line.
699
700* aven: Setting view to North, South, East, or West is now animated like
701  the tilt from plan to elevation.
702
703* aven: Fix presentation saving to also write "." for decimal points and
704  presentation loading to accept either "." or ",".
705
706* (Unix version): aven: Add text for all toolbar items so that aven
707  will work with the Gnome desktop preference for displaying toolbars as
708  icons with text or just text (wxWidgets needs fixing first though).
709
710* (Unix version): aven: Remove the ability to detach the menu bar (yell
711  if you actually used it and I'll restore it!)
712
713* aven: Add "all survey files" option to the "open file" dialog.
714
715* (MS Windows version): aven: Fix cursor keys to pan survey.
716
717* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
718
719* (MS Windows version): Fix installer to work on Windows 2000 or XP if
720  run by an unprivileged user.
721
722* (MS Windows version): Upgrade to the latest version of InnoSetup (the
723  installer builder we use) and include new installer translations for
724  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
725
726* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
727  translations of messages for wxWidgets (the GUI library we use).
728
729* aven: Disable "Highlight exported points" if there aren't any.
730
731* Updates to French translation from Michel Bovey.  Also updates to German,
732  Italian, Catalan, Spanish, and Romanian translations.
733
734* (Unix version): test suite: fix smoke test to pass even without X running
735  (it was meant to but the code had a bug).
736
737* aven: Check if OpenGL is available and exit cleanly with a helpful error
738  if it isn't.
739
740* (Unix version): aven: Fix --help and --version to work without a working
741  X display (provided it's built with wxWidgets 2.5.1 or newer).
742
743* aven: Automatically select the presentation tab of the notebook when the user
744  selects "New Presentation" or "Open Presentation".
745
746* aven: Fix "Delete" in the presentation list to not get passed on (and so not
747  reset to default view as well).
748
749* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
750  empty.
751
752* aven: Fix Cursor Up and Down in the presentation list to move the highlight
753  up and down instead of being passed on and moving the survey.
754
755* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
756  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
757  Safari 2.0.3, and InkScape 0.42.
758
759* aven: Put a 5mm border around exported SVG files to allow for station markers
760  and non-zero width lines.
761
762* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
763  was turned on.
764
765* aven: Actually close the file we're exporting which fixes problems with it
766  not always being fully written.
767
768Changes in 1.1.7 (2005.10.18):
769
770* cavern: Add validity checking for dates in *date commands (with feature
771  test in testsuite).  A date entered as just "year" or "year.month" now
772  becomes a date range for the relevant period (previously it became a single
773  date near the middle of that period).
774
775* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
776  with MS Windows).
777
778* extend: Default output name for a file called input.3d is now input_extend.3d
779  rather than just extend.3d (which was annoying if you wanted to extend
780  several surveys in the same directory).
781
782* aven: OpenGL 2.0 always includes support for point sprites so rework
783  our check for them to include that knowledge.
784
785* aven: Regenerate depth bar if user switches to/from metric units.
786
787* aven: Don't clear the "there" mark just because the mouse pointer has
788  moved off a station.
789
790* aven: When processing a .svx file, put the resultant .3d file in the
791  same directory (since that's where we then try to load it from).
792
793* aven: Fix labelling of date colouring on 32 bit platforms.
794
795* aven: If "colour by date" is on and we load a survey with no date info
796  (or all surveyed on the same date) then set "colour by none".
797
798* aven: Make the error dialog modal and remove a signal handler once it
799  has fired to prevent endless (or seemingly endless) cascades of error
800  dialogs.
801
802* aven: Enforce a minimum object volume diameter of 1m to avoid problems
803  if a survey file with only one station in is loaded.
804
805* aven: Fix problems with indicators disappearing when we're drawing
806  blobs and/or crosses the slow (but always supported) way.  (Problem
807  introduced in 1.1.6).
808
809* (Unix version): aven: Really stop setting extra toolbar margin when using
810  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
811  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
812
813* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
814  we've been compiled with, and which GTK+/Motif version where appropriate.
815
816* (Unix version): Fixed build on Fedora Core 3.
817
818* documentation: Updates to 3d file format specification from Mike McCombe.
819
820Changes in 1.1.6 (2005.10.10):
821
822* (MS Windows version): Distribution is about a third smaller than 1.1.5
823  (mostly because mingwm10.dll is no longer required).
824
825* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
826  it, showing cavern's output in a window (with errors and warnings clickable
827  to load the offending file into an editor), and then loading the resulting
828  3d file.
829
830* aven: Added "Colour by Date" option.
831
832* aven: Disable "Colour by Depth" option if there's no elevation variation.
833
834* aven: Don't crash if trying to load a survey with no elevation variation.
835  Instead turn off depth colouring.
836
837* aven: Export as HPGL added.
838
839* aven: Improved update of mouse coordinates and measuring line (thanks to
840  Martin Green).
841
842* aven: Show the coordinates of either the mouse pointer or the nearest
843  survey station to it (if there is one near enough).  Showing both was
844  confusing and meant the status bar overflowed on smaller displays.
845
846* aven: When printing an extended elevation, don't show bearing and elevation.
847
848* aven: Don't lock "flat" surveys which aren't extended elevations - a
849  flat survey with LRUD data isn't flat any more!
850
851* aven: When we have to draw blobs and crosses the slow way (because the
852  graphics hardware doesn't support the fast way), draw them so that they
853  should appear at the correct depth into the 3D scene instead of on top
854  of everything else.
855
856* aven: Make "play presentation backwards" icon green to match the other
857  presentation icons.
858
859* (MS Windows version): aven: Mouse clicks on the survey view now set the
860  keyboard focus there.
861
862* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
863
864* (MS Windows version): aven: Fix redrawing of measuring line.
865
866* cavern: Store dates for img_XSECT.
867
868* cavern: Fixed small one-off memory leak if you specify -o more than once.
869
870* (Unix version): Check environmental variable LC_MESSAGES when deciding what
871  language to use for messages.
872
873* (MS Windows version): "Print" on a 3d file now prints through aven rather
874  than the separate printer driver (Unix has done this for some time).
875
876* Removed old printer drivers.
877
878* img library: When creating a 3d file, ignore img_XSECT if we've been asked
879  to write a file format version which doesn't support it.
880
881Changes in 1.1.5 (2005.09.20):
882
883* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
884
885* aven: Make blobs round like they are in Survex 1.0.
886
887* aven: If the graphics drivers don't support drawing blobs using OpenGL
888  point markers, fall back to drawing filled circles.
889
890* aven: If the graphics drivers support it, draw crosses as texture mapped
891  OpenGL point markers which is much faster.
892
893* aven: Cross size increased to match Survex 1.0.
894
895* aven: We must update which blobs are displayed if display of surface or
896  underground legs is toggled.
897
898* cavern: Fix handling of a *solve followed by survey data, none of which is
899  attached to the previous data.
900
901* cavern: Fixed "No survey data" error when a *solve is followed by another
902  *solve (or the implicit solve at the end of processing) with no data between
903  them.
904
905Changes in 1.1.4 (2005.09.19):
906
907* aven: Added Aven's icon to the "About" dialog.
908
909* aven: Use localised character for the decimal point (e.g. "," in most
910  continental European countries).
911
912* aven: Previously the survey tree would get focus and then take keypresses
913  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
914  operate on the cave, and transfer the input focus across when we do.
915
916* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
917
918* aven: Speed up intialisation by delaying creation of OpenGL lists until
919  they're needed.
920
921* aven: Added Mark Shinwell's bounding box with shadow of the survey.
922
923* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
924
925* aven: Reworded "Restore Default Settings" as "Restore Default View".
926
927* (Unix version): aven: Set sensible default margins for printing and preserve
928  any margin values the user specifies between runs (previously margins
929  defaulted to 0 each time aven was run).
930
931* Documentation: Document *DATA PASSAGE in the manual.
932
933Changes in 1.1.3 (2005.09.07):
934
935* (Microsoft Windows version): Fixed build problems.
936
937* cavern: Allow OMIT character (-) for left/right/up/down.
938
939* aven: Remove an unnecessary menu separator.
940
941* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
942
943* aven: Make the tooltip for "Hide" show the number of found stations.
944
945* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
946
947* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
948  when there's a presentation loaded.
949
950* aven: Make entrances green in side panel tree list to match green blobs used
951  in cave view.
952
953* aven: Don't show surface labels if we're not showing surface data, etc.
954
955* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
956  make "Space" the key for this.  Keep Return working "Stop Rotation" so
957  existing users are happy, but don't advertise it.
958
959* aven: Normalise filename by adding any extension used, and use the normalised
960  filename for file history and window title.
961
962* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
963  as the toolbar buttons already have a sensible margin - the extra margin is
964  only needed with GTK1.2.
965
966* aven: Fix handling of plumb legs in tube model.
967
968* aven: Fixed swapped L and R in tube model.
969
970* extend: Preserve UD cross-section information in extended elevation.
971
972* extend: Add new messages for John Pybus' enhancements.
973
974Changes in 1.1.2 (never formally released):
975
976* Added support for LRUD data in .svx files, in .3d files, and aven can
977  now load and display it on screen and on printouts.  The ability to "fake"
978  LRUD data in aven is gone for now but will reappear in some form later.
979
980* cavern: Removed support for writing Chasm's 3dx format.  We're going to
981  fold any desirable missing chasm functionality into aven.
982
983* aven: Rearranged mouse actions as discussed on the mailing list.  Added
984  cursors for each different mouse action to help the user learn what each
985  does.  Also added cursors for the "compass" and "clino" as well as the
986  scalebar to suggest to the user that they can be dragged to change the view.
987
988* (Unix version): aven: Don't segfault if LANG isn't a known language.
989
990* tests/smoketest.tst: If X windows is running, check that we can run aven
991  with --help and --version.
992
993* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
994  no results are listed for it.  This revealed that there was a "newline" test
995  which should have been called "badnewline", and was a broken testcase too!
996  Fixed all these problems.
997
998* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
999  and omitted forward compass/clino readings in Compass DAT files.  Added
1000  a feature test for this to the testsuite.
1001
1002* It no longer makes sense to have an option not to build aven or to build aven
1003  without OpenGL so remove old machinery for this from configure and the
1004  sources.
1005
1006* (Unix version): configure: Check if "-lXxf86vm" is needed.
1007
1008* configure: Better output for strcasecmp test.
1009
1010* aven: Fix crosses to work much better.  Not a total fix - their position
1011  in the Z buffer isn't correct and they're rather slow to plot.
1012
1013* aven: Don't regenerate the hittest grid every time the mouse moves while
1014  animating, which solves the mysterious pausing effect (thanks go to Martin
1015  Green for spotting this!)  Also clear all the status bar coordinates when
1016  animating.
1017
1018* aven: Sort out clashing menu shortcuts in some languages.
1019
1020* aven: Fixed compilation problem on x86_64
1021
1022* SPUD: Pruned out stuff which has been done or which is not actually relevant
1023  to this branch.
1024
1025* Merge various changes from 1.0 branch:
1026
1027  + aven: Port over "printing from aven" functionality.
1028
1029  + aven: Port over "export as" functionality,
1030
1031  + Add David Loeffler's vim mode for .svx files.
1032
1033* aven: Fix check for whether a label is behind us in perspective view.
1034
1035* aven: Don't use an opengl list for drawing the indicators - we typically make
1036  a new list each time we plot them anyway.
1037
1038* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1039
1040* aven: Set icon on non-Windows platforms too.  This means that with
1041  WindowMaker on Unix you get an icon on the AppIcon by default.
1042
1043* configure: Update wxWindows checks to handle newer wx versions.
1044
1045* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
1046  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
1047  for anyone building from CVS).
1048
1049* acinclude.m4: Quote macro name for fix autotools warning.
1050
1051* Documentation: "tilt up" is "'" not ",".
1052
1053* aven: Add support for mousewheels (to tilt the cave).
1054
1055* aven: Fixed twisted transitions to and from pitches in certain cases.
1056
1057* aven: Pick a sensible initial window size when the user's desktop is spread
1058  over more than one monitor (works best with wx2.5 or newer, but try to do
1059  better with wx2.4 or earlier as well).
1060
1061* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
1062  contents being visible before any survey is loaded.
1063
1064* aven: Allow a coloured texture to be used
1065
1066* aven: Don't initialise until we have data (to the user, this means the window
1067  is default colour (grey for most systems) not black until a survey is
1068  loaded).
1069
1070* aven: Fixed weird "shadowed" icons.
1071
1072Changes in 1.1.1 (2004-10-06):
1073
1074* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
1075  startup.
1076
1077* aven: Delay loading the bitmap for the "About" dialog until it is first
1078  needed.  We want start up to be as quick as possible.
1079
1080Changes between 1.0.32 and 1.1.0 (never formally released):
1081
1082* NOTE: Survex 1.1.X releases are development snapshots made available for
1083  the purposes of allowing wider testing and getting more user feedback.  Once
1084  the code has stabilised the version number will be raised to 1.2.0.
1085
1086* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
1087  you're using Windows 95 - these can be obtained from:
1088  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
1089
1090* aven: Solid passages - passage dimensions are currently inferred from
1091  the leg length (pretty effective as you can measure longer legs in
1092  larger passages).  Use of real LRUD data coming soon...
1093
1094* aven: Depth colouring is now continuously varying.
1095
1096* aven: Colour by depth can now be turned off (and there's the start of a
1097  framework for properly implementing colour by date, error, etc).
1098
1099* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
1100  match (? matches any character, * matches any number of characters).
1101
1102* aven: We now use the status bar for coordinates, distances, etc to make
1103  better use of screen space.
1104
1105* aven: Full screen mode (F11).
1106
1107* aven: Perspective view.
1108
1109* aven: Context sensitive cursor shape - needs more work.
1110
1111* aven: Mouse actions changed (hopefully they're now more natural, but
1112  you may find the change disorientating - feedback wanted on this).
1113
1114* aven: Added "presentations" which allow you to set up fly-through paths
1115  and load/save/run them.
1116
1117* aven: A presentation can be exported as a movie file.
1118
1119* aven: Added Save screenshot facility.
1120
1121* aven: Depth fogging option.
1122
1123* aven: Added Smooth Lines option.
1124
1125* aven: Added Textured Walls option.
1126
1127* aven: If a survey has surface legs but no underground legs, default to
1128  showing the surface legs.
1129
1130* cavern: Dates given to *date are now stored in the 3d file.
