3Changes in 1.2.14 (2014-06-??):
4
5* aven: You can now quickly zoom to a particular area by holding down the
6  "Shift" key and dragging with the left mouse button to create a rectangular
7  "rubber band box" around the area you wish to zoom to.  If you release the
8  "Shift" key while still dragging, the box is centred on the start point
9  rather than having one corner there.
10
11* aven: Fix exporting of passage tubes in elevations and extended elevations
12  - previously up and down were getting drawn across the page!
13
14* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
15  1.2.13.  (Reported by Brian Clipstone)
16
17* aven: Fix the conditions on which the menu item "Cancel measuring line" is
18  enabled - previously it was hard to actually cancel it via the menu.
19  Reported by Hugh St Lawrence.
20
21* aven: Fix wx assertion failures when showing hit test debug view on platforms
22  such as 64-bit Linux.
23
24* aven: When viewing from above, show "Plan" above the "clino" which indicates
25  the tilt angle (instead of "Elevation -90°").
26
27* aven: The extended font data now loads faster, and also uses less memory on
28  64-bit platforms.
29
30* aven: Dragging the vertical divider between the side panel and the 3D view
31  now only updates when you finish the drag, as redrawing continuously just
32  looks clunky except on an ultra-fast machine.
33
34* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
35  the space available in the aven UI.
36
37* cavern: Add a *cs command to set the coordinate system.  Currently only the
38  parsing part is implemented - using this command won't actually do anything.
39
40* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
41  and handle it in the same way as the "DUPLICATE" flag in .svx files.
42
43* (Microsoft Windows version): Include dump3d in the installer.
44
45* Fix a compiler warning.
46
47* Improve test coverage.
48
49Changes in 1.2.13 (2014-05-15):
50
51* aven: Fix --print option to wait for printing to happen before exiting
52  (previously it would exit right after opening the print dialog, so you
53  couldn't actually print anything out using it).
54
55* aven: Increase the threshold for how close the pointer needs to be to a
56  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
57  Hugh St Lawrence.
58
59* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
60  if increasing the minimum pointer to station threshold helps Hugh's problems
61  with using aven on a touch screen device.
62
63* aven: The measuring line was unable to see stations which had just been
64  revealed by toggling surface or underground legs on - this is now fixed.
65
66* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
67  many entries are in each box (toggled by F3).
68
69* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
70  off and back on.
71
72* aven: Create the empty hit-test grid data structure lazily, to reduce start
73  up time a little.
74
75* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
76  and *end commands to instead talk about "survey names".
77
78* cavern: For ages cavern has warned if you reentered a survey, but this
79  warning was suppressed if it occurred at the same line of the same file as
80  the survey was first entered, but this can only happen if you include the
81  same survey file more than once, which isn't a sensible thing to do for a
82  file with actual survey data in (you might reasonably do it to set up survey
83  grade details or something like that).  The warning is now given in this
84  situation too.
85
86* cavern: After 5 warnings about reentering a survey we give up warning about
87  it, but we used to keep reporting where the survey was originally entered -
88  this secondary diagnostic message is now silenced when the main message is.
89
90* (Microsoft Windows version): Compile C code with optimisation on.
91
92* Add the start of a Russian translation, with messages take from therion.
93
94* Minor translation updates to French.
95
96* Fix compiler warning from GCC.
97
98* Testsuite improvements:
99
100  + Test that "..." anon station works.
101
102  + cavern.tst: Check number of errors returned by all testcases which should
103    fail and give an error count.
104
105  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
106
107Changes in 1.2.12 (2014-04-14):
108
109* aven: Fix measuring line to show change in altitude rather than altitude
110  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
111  Clipstone.
112
113* aven: Fix printing when built with wxWidgets 3.0.
114
115* aven: Several visual improvements to printouts:
116
117  + Move the numbers below the scale bar down a little so that they don't
118    overlap the scale bar ticks.
119
120  + Set the clipping region after we draw the page border and info box to avoid
121    clipping the border in print preview.
122
123  + Tidy up the appearance of the compass and elevation arrow.
124
125* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
126  <http://bugs.debian.org/739332>.
127
128* aven: Fix to build with older libav where avcodec_free_frame() isn't
129  available.
130
131* (Linux version) survex.spec: Update spec file used for building RPM packages.
132
133* (Unix version): Add "Keywords:" entry to .desktop files.
134
135* (Unix version): Enable large file support, mostly to support filing systems
136  which return 64 bit inode values, such as CIFS mounts.
137
138* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
139  rather than any character which is a letter in the current locale.
140
141* Various translation updates.
142
143Changes in 1.2.11 (2014-01-28):
144
145* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
146  Reported by Kevin Dixon.
147
148* aven: Embed the font data for the first 256 Unicode characters for use in the
149  survey pane into the compiled aven binary to reduce start up overhead.  Any
150  additional characters needed are loaded from a data file only if/when a
151  character >= U+100 is actually needed (as before).
152
153* aven: Fix display of Unicode characters above 256 when there's a character
154  <= 256 earlier in the same string.
155
156* aven: Use the actual width of Unicode characters above 256 rather than
157  assuming they are 16 pixels wide.
158
159* aven: If full screen, don't show the side panel when a new file is opened
160  (e.g. via Ctrl+O).
161
162* aven: Don't give an assertion failure when showing passages for a cave with
163  no vertical extent.  Reported by Jonny Prouty.
164
165* aven: Change terminology in print dialog - say "legend" instead of "info
166  box".
167
168* aven: Add option to show the tilt angle as a percentage gradient.
169
170* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
171  indicators.
172
173* aven: All length units are now translatable.
174
175* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
176  will reduce code size and also the number of deprecation warnings about
177  gluErrorString on Mac OS X 10.9.
178
179* (Microsoft Windows version): aven: Try to work around redraw issues related
180  to the measuring line by redrawing the whole window, which doesn't seem to be
181  measurably slower.
182
183* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
184  give an error rather than quietly ignoring the attempt.
185
186* cad3d: Make cad3d remap control characters and spaces in station names when
187  generating PLT output in the same way aven does.
188
189* Various translation updates (particular thanks to Eric Madelaine and Dennis
190  Baudys), including the start of a Bulgarian translation, with messages taken
191  from Therion and elsewhere.
192
193* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
194  GetUserDefaultUILanguage() to get the UI language to use.  For older
195  versions, continue to use GetUserDefaultLCID().
196
197* (Microsoft Windows version): The Indonesian translation will now be used
198  automatically when the system language is set to Indonesian.
199
200* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
201  A. Riggs for his work on this.
202
203* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
204  checksum check for the downloaded wx sources.
205
206* Fix a lot of the compiler warnings when building with clang.
207
208* doc/manual.sgml: Add missing quantities to the list documented as accepted by
209  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
210  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
211  mentioned in list of the units that can be set for them); COUNT (missing
212  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
213  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
214
215* Test suite: Improve test coverage for cavern.
216
217Changes in 1.2.10 (2014-01-15):
218
219* aven: Fix assertion if two mouse buttons are held down at the same time.
220  If dragging with more than one mouse button held down, releasing one causes
221  another which is still held down to take effect.  Reported by Brian
222  Clipstone.
223
224* aven: If we fail to start the external editor when the user clicks on an
225  error or warning from cavern, show an error box.
226
227* aven: If the survey has a title, add it as a top-level <title> element to
228  exported SVG files.
229
230* aven: Escape '<', '>', and '&' in labels in exported SVG files.
231
232* aven: In GPX export, set the <time> element to the datestamp from the 3d
233  file.
234
235* aven: Don't try to write the title if it isn't set or is empty when exporting
236  GPX files.
237
238* aven: Don't bother looking up the printer page setup info when exporting.
239
240* (Microsoft Windows version): aven: Fix crash on "File->Print" or
241  "File->Export" under Windows XP, reported by Brian Clipstone.
242
243* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
244  encoded filename which could occur if run without being asked to load a file
245  on startup.
246
247* (Microsoft Windows version): aven: Compile with optimisation on.
248
249* img library, aven: Although processed CMAP data files are often referred to
250  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
251  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
252  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
253  continue to do so in case anyone is relying on it, but also check for the
254  other extensions.
255
256* img library: Add new "datestamp_numeric" field to struct img giving the
257  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
258  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
259  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
260  timezone wrong.
261
262* img library: Fix my_strcasecmp() to handle top-bit set characters better.
263
264* cavern: Fix NULL pointer dereference when processing Compass DAT file without
265  'SURVEY DATE:'.
266
267* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
268
269* doc/manual.sgml: Note the station length limit Smaps used.
270
271* Fix some compiler warnings if built with glibc's fortify source feature
272  enabled.
273
274Changes in 1.2.9 (2014-01-08):
275
276* Document --3d-version in cavern man page and the manual.
277
278* aven: Fix compilation error in movie export code with recent libavi.
279
280* aven: Fix warning on stderr when export a movie as MPEG.
281
282* img library: In non-hosted mode, don't define GETC and PUTC if they're
283  already defined, to allow easy overriding with getc_unlocked() and
284  putc_unlocked() (which are significantly faster on Linux).
285
286* img library: In non-hosted mode, check that int is at least 32 bits,
287  and if not, use long.  In practice, platforms with 16 bit int are mostly
288  obsolete, but it's not hard to be portable here.
289
290* img library: Add test that img.c and img.h compile in non-hosted mode
291  (regression test for issue fixed in 1.2.8).
292
293* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
294
295* Update translations from launchpad and from existing similar messages.
296
297* Fix some compiler warnings.
298
299Changes in 1.2.8 (2013-10-29):
300
301* cavern: Fix handling of anonymous wall stations ('..' by default) to
302  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
303  Holder.
304
305* cavern: Tweak .err file output not to lose the space in front of certain
306  statistics when the value gets large.
307
308* cavern: Eliminate redundant progress message when solving simultaneous
309  equations.
310
311* aven: Add a format drop down to the export dialog, and only show fields which
312  are meaningful and supported for the currently selected export format.  The
313  format defaults to that used most recently.  The "Elements" and "View" boxes
314  have been swapped in the print and export dialogs as that layout works much
315  better when the "View" box is hidden.
316
317* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
318  - now works again.  Reported by Anthony Day.
319
320* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
321  this release the projection which the survey coordinates are in defaults
322  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
323  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
324  projection string.  The ability to specify this projection in a better
325  way is coming soon.
326
327* aven: New export options "Origin in centre" and "Full coordinates" - the
328  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
329
330* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
331  time ago, so update references.
332
333* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
334  with wxMSW 2.9.5.  Reported by Brian Clipstone.
335
336* aven: Make right click in an empty presentation mark the current position and
337  open it to edit, instead of crashing.
338
339* aven: Update movie export code to work with latest libav API.  Reported by
340  Sebastian Ramacher.
341
342* aven: Improve reporting of errors during the process of exporting a movie.
343
344* aven: Don't try to close the movie if we aren't producing one.
345
346* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
347
348* aven: Fix to build with wxMSW 2.9.5.
349
350* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
351
352* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
353  ago, so add a new --skencil option to specify this output format.  The old
354  name (--sketch) is still recognised for compatibility.
355
356* cad3d: Make --marker-size work for Skencil and SVG output.
357
358* dump3d: Make --show-dates option show dates for XSECT.
359
360* img library:
361
362  + Fix to work once more when used outside of Survex (missing definition of
363    max() macro and a bad call to free() in img_close() for a file opened for
364    reading).
365
366  + Use lround() instead of round(), and make the tests around whether we use
367    the library function or the our fallback implementation saner.
368
369  + Fix // comments in C code for portability to pre-C99 compilers which don't
370    support these as an extension.
371
372  + Can now be compiled as C++ as well as as C.
373
374* (Microsoft Windows version): The installer is now built with a newer version
375  of Innosetup, and includes translations for all the languages which Survex
376  itself has any translations for.
377
378* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
379
380* Minor translation updates.
381
382* tests/Makefile.am: Distribute files for "normal_bad" testcase.
383
384Changes in 1.2.7 (2013-07-27):
385
386* Add support for anonymous stations, which are indicated by one, two or three
387  separator characters - with the default separator of '.', that means '.',
388  '..', and '...' are anonymous stations.  Single separator ('.' by default)
389  is an anonymous non-wall point, double separator ('..' by default)
390  is an anoymous wall point at the end of an implicit splay), and triple
391  separator ('...' by default) is an anoymous point (with nothing special about
392  the leg).  A new *alias command allows '-' to be mapped to '..' for
393  compatibility with pocket topo: *alias station - ..
394
395* New version 8 of the 3d format:
396
397  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
398
399  + New explicit file-wide flag for 'this is an extended elevation', rather
400    than modifying the survey title to indicate this.
401
402  + The survey prefix is often unchanged from one leg to the next, so use a
403    spare flag to compactly indicate when there's no label change.
404
405  + The data style of each leg is now stored.
406
407  + The "processed at" time is stored as seconds since 1970 rather than a
408    human-readable string.
409
410  + Since 3d v8 features significant changes to the format, the format
411    documentation for v7 and earlier has been split off into 3dformat-old.htm.
412
413* img library:
414
415  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
416
417  + Handle .pos files containing unnamed stations - don't suck the next line in
418    as the station name, and set img_SFLAG_ANON for them.
419
420  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
421    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
422    elevation, in place of appending " (extended)" to the title.  Internally we
423    still append this to the title (and remove it upon reading) when writing
424    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
425    explicitly in the file.
426
427  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
428
429* aven:
430
431  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
432    now, and the wx developers consider even 2.8 to be rather long in the
433    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
434    formally dropping support for older versions allows a number of workarounds
435    to be removed from the aven source code.  Also, features deprecated in
436    wxWidgets 2.9 are no longer used in our code.
437
438  + Don't run incremental search on every key-press, as on a slow machine the
439    short initial search(es) will take a while but not be useful.  Instead only
440    actually run the search when we're told there are no more key-presses
441    queued up.
442
443  + Implement support for including cross-section information in exported SVG
444    and DXF files (ticket#4).  The DXF export is untested currently.
445
446  + Show splay legs faded by default, with menu options to hide them or show
447    them like other legs.
448
449  + Speed up loading a .3d file with cross-sections by using a map to convert
450    station names to positions.
451
452  + In the cavern log window, don't highlight a file:linenumber if there's no
453    message after it, which avoids highlighting the "Included from" lines
454    wrongly.
455
456  + Fix not to crash when trying to report an error while starting up.
457
458  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
459    the OS X standard shortcut Shift-Command-F (previously we used F11, but
460    that's used by the desktop).
461
462  + Add checks for errors when reading the font file.
463
464  + Remove useless extra quoting when invoking vim to show the location of an
465    error from cavern.
466
467  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
468
469  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
470    in the dialog in sync.
471
472* cavern:
473
474  + Demote errors about invalid dates to warnings, since we've accepted *date
475    for ages without any checks on the value, and so existing datasets
476    probably contain invalid dates and dates in other formats.  (ticket#19)
477
478  + New *alias command allows '-' to be mapped to '..' for compatibility with
479    pocket topo: *alias station - ..
480
481  + We want to warn if there's a clino reading which it would be impossible to
482    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
483    read "93" (it's probably a typo e.g. for "39").  However, the gradient
484    reading from a topofil is typically in the range 0 to 180, with 90 being
485    horizontal.  Really we should allow the valid range to be explicitly
486    specified, but for now we infer it from the zero error - if this is within
487    45 degrees of 90 then we assume the instrument can read between 0 and 180
488    degrees.
489
490  + If the survey isn't all connected, still run survey tree checks and report
491    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
492    Dixon for the report which highlighted this issue.
493
494  + Report a warning if *begin SURVEY has a separator character in SURVEY.
495
496  + Report column numbers as well as line numbers for some cavern errors and
497    warnings.
498
499  + Adjust width of node stats table to fit longest count when there are more
500    than 9999 of a particular order of node.
501
502  + If the argument to *include has an opening double quote but the closing
503    double quote is missing, then skip trying to open the file.
504
505  + Move "Station X referred to just once" warning after non-existent survey
506    check - if both fire, the non-existent survey error is likely to be more
507    relevant.
508
509  + We no longer follow an error for a bad reading in passage data with a bogus
510    "End of line not blank" error, but instead check the remaining readings on
511    the same line.
512
513  + We no longer follow an error about OMIT for a required reading with a bogus
514    "End of line not blank" error.
515
516  + Report an error if the scale factor in *calibrate is zero - it doesn't make
517    sense and probably means someone reversed the arguments to *calibrate.
518
519  + Report the parent include files starting from the outermost, as that's more
520    logical when there are multiple levels involved.
521
522  + If we were expecting a numeric field and instead get something which starts
523    with '+', '-', or '.' but which isn't a number, then fix the error to
524    include that character in the token reported.
525
526  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
527    first item.
528
529* cad3d: Check for errors from img_rewind() and report them.
530
531* dump3d:
532
533  + Build, install and package dump3d as standard - it's useful for grabbing
534    info from 3d files in scripts.
535
536  + Add --show-dates option.
537
538  + Show only 2 decimal places on coordinates and passage dimensions.
539
540  + Report the data style of legs.
541
542  + Report if the file is an extended elevation.
543
544  + Report img_STOP as STOP rather than CODE_0xffffffff.
545
546* Test suite:
547
548  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
549    expected output so it passes reliably.
550
551  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
552    'Deleted' stations upon failure are the more natural way round.
553
554  + Add more testcases, expand some existing testcases, and add expected output
555    for more.
556
557* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
558  appropriate C and C++ compilers to use, and link mingw build statically to
559  avoid needing the libgcc DLL (which newer GCC seems to have by default).
560
561* (Unix version): When determining the character set for command-line tools,
562  check environmental variable LANG after LC_ALL and LC_CTYPE.
563
564* When determining the language, check environmental variable LC_ALL before
565  LC_MESSAGES and LANG (but after SURVEXLANG).
566
567* If we don't find the message file, only give an error if it was specified
568  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
569  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
570  settings.
571
572* There are a handful of hard-coded English message strings for reporting
573  errors trying loading message files, etc.  These are all now ASCII, as if we
574  fail trying to open a message file, it's more likely the encoding isn't
575  set correctly.
576
577* Prune strings we are no longer using and are probably unlikely to use again
578  into a new file po_codes_dead, so that translators don't get presented with
579  them to translate.
580
581* Merge lots of translation updates.  Most translations are now complete or
582  close to complete.
583
584* Add start of Indonesian translation from Arief Setiadi Wibowo.
585
586* Fix various compiler warnings when building from source.
587
588* Include scripts gdtconvert and gen_img2aven in the source distribution.
589
590Changes in 1.2.6 (2012-02-23):
591
592* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
593
594* (Microsoft Windows version): Include JPEG images for aven in the installer
595  package (ticket#35).
596
597* cavern: If we have a reference to a station in a non-existent survey, give a
598  helpful error rather than saying the station hasn't been exported from the
599  survey.  (Bug reported by Martin Green via email)
600
601* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
602  Kahler.
603
604* findentrances: Add findentrances utility from Olaf Kahler which produces a
605  .gpx file with waypoints for entrances.  This needs libproj so is disabled
606  by default for this release - to enable it install the development stuff for
607  libproj and build survex with:
608
609      make FINDENTRANCES=findentrances
610      make install FINDENTRANCES=findentrances
611
612* dump3d: Add support for showing img_ERROR_INFO items.
613
614* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
615
616* Incorporate a French translation from launchpad I'd previously copied the
617  English version of by mistake.  Attempt to correct mistranslation of "survey
618  file".
619
620Changes in 1.2.5 (2012-01-03):
621
622* aven:
623
624  + The survey tree in the left panel is now in sorted order once more.
625
626  + No longer fails with an assertion if used for a long time (we were leaking
627    an OpenGL list each time one had to be regenerated).
628
629  + Now builds with newer FFmpeg library.
630
631  + Draw measuring line in front of the indicators rather than behind them.
632
633  + Loading a new file (or reloading the current one) no longer invalidates
634    the OpenGL lists for the compass and clino, so will be a fraction faster.
635
636* Improve handling of attempts to look up translated messages before the
637  message subsystem is fully initialised (which only happens if there's an
638  error early on).
639
640* Improve the survex(7) man page text, and fix it to be marked as section 7 in
641  the man page source as well as in the filename.
642
643Changes in 1.2.4 (2012-01-01):
644
645* aven:
646
647  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
648    initialised, which doesn't cause problems in some machines, but causes aven
649    to abort on others.  This is now fixed, and there's a check in place to
650    help avoid similar issues in future. (ticket#34)
651
652  + Always use metres or feet for the depth colour key, and chose a consistent
653    precision by looking at the depth range. (ticket#30)
654
655  + Show the depth units below the colour bar rather than after every value.
656
657  + When zooming way in, stay in metres rather than switching to cm.
658
659  + On the scale bar, say “1 mile” rather than “1 miles”.
660
661* Translation updates for Catalan, French and Slovak.
662
663Changes in 1.2.3 (2011-12-31):
664
665* Fix to build with wxWidgets 2.9.2.
666
667* (Mac OS X version):
668
669  + Processing .svx files from aven now works.
670
671  + Remove spurious blank lines from the licence text in "Get Info".
672
673  + Don't create the help menu at all, as it is empty (because the "About"
674    entry goes elsewhere) and sometimes seems to appear in the UI.
675
676  + INSTALL.OSX: Update to reflect current status.
677
678* aven:
679
680  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
681
682  + Improvements to text plotted on the survey pane:
683
684    - Support plotting Unicode character points > 256 by lazily loading the
685      data for them from the font file and plotting them with a direct call to
686      glBitmap(), which is slower but doesn't require a display list per
687      character.
688
689    - Adjust the spacing from fixed width to putting a one pixel gap either
690      side of each one character (so two between adjacent glyphs).  Mostly this
691      reduces the horizontal width, but it adds a pixel for characters like "m"
692      and two in a few cases.
693
694    - Fix .pixelfont file generation to correctly handle characters wider than
695      8 pixels.
696
697  + Fix expected cross shape so don't always reject using texture mapping to
698    draw crosses.
699
700  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
701    as those consisting of just one.  Previously we would trip over the empty
702    tube later.  Such tubes can for example be created by extend if a splay shot
703    is the start or end of a tube.
704
705  + Make the green colour used for entrances in the survey tree the same
706    (slightly darker than before) green used for the entrance blobs.
707
708  + Report the version of the library we're actually running with if built
709    against wx >= 2.9.2.  Make it clear that the version reported is the
710    version *built* with for wx < 2.9.2.
711
712* extend:
713
714  + Copy the end markers for passage tubes.
715
716  + Preserve left and right data for tubes (previously they were set to -1.0
717    which means "no info").
718
719* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
720  was no longer used - it certainly is!
721
722* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
723  messages, and curly single right quote instead of straight ASCII apostrophe.
724  Fall back to using straight ASCII versions if we can't represent them in the
725  current character set.
726
727* Translation updates for Catalan, French, Slovak and Spanish.
728
729* Test suite:
730
731  + Add test coverage for interleaved diving data.
732
733  + Add testcase for diving data with topofil-style distance.
734
735Changes in 1.2.2 (2011-10-06):
736
737* aven:
738
739  + Replace the textured-mapped font drawing with an approach based on
740    glBitmap.  This doesn't suffer from the character alignment issues which
741    the textured-mapped fonts had, and is actually significantly faster on some
742    machines.  The current font used is (mostly) fixed-width, but this isn't an
743    inherent limitation - it was just the easiest font data to convert to a
744    usable format.
745
746  + Fix assertion failure due to rounding differences on loading certain .3d
747    files.  (ticket#26)
748
749  + Fix assertion failure when turning on 3D passages if they stick out higher
750    or lower than any station.  (ticket#29)
751
752  + Fix grid not to disappear when blobs are turned on and blobs are drawn
753    using lines.
754
755  + If a degree sign isn't available in the character set in use, transliterate
756    it to 'dg' rather than skipping it.
757
758  + Fix message which should have been a degree sign but got lost in the format
759    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
760    that bearings in the status bar now have a degree sign after them if they
761    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
762
763  + Fix print dialog to calculate the scale required for "One page" right
764    before it calculates how many pages are required, so we don't end up
765    something other than 1x1 being shown when the user changes settings.
766
767  + Update the calculations for picking a scale and for deciding how many
768    pages are needed to take into account the change in info box height made
769    in 1.2.1.
770
771Changes in 1.2.1 (2011-10-04):
772
773* Translation updates for US English.
774
775* aven:
776
777  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
778    it now shows colours for dates and errors as well as depths.
779
780  + In the colour key for "colour by date", change "No info" to "Undated".
781
782  + Remove the dark grey background from the colour key and just put a single
783    pixel black border around the colours.  This is more in keeping with the
784    other controls, and means the colours are now on a black background so more
785    visually similar to the survey legs.
786
787  + Move the colour key's "Undated"/"Not in loop" entry down a little to
788    improve the appearance.  Make each section a pixel taller.
789
790  + Allow "Colour by X" to be selected even if there's no data for X or only a
791    single value of X used (the colour key is much smaller in these cases, and
792    does still provide some useful information).
793
794  + Fix incorrect calculation of depth colouring for survey legs which straddle
795    a depth band boundary.
796
797  + The scale bar, compass, clino, and colour key now all have right click
798    menus which allow related actions to be performed (especially handy in
799    full-screen mode).
800
801  + Improve the font used on the survey pane - it now contains the '-'
802    character (so the clino now shows negative angles as negative, and dates
803    in the colour key are now hyphenated).  Also the spacing and alignment
804    are a little better, though still not perfect.
805
806  + PLT file export now handles spaces and control characters in station names
807    by escaping them with '%' as in URLs.
808
809  + Pressing "Enter" on a station in the tree control now centres the view on
810    that station.
811
812  + The scale bar is now cached in an OpenGL display list since it often gets
813    redrawn exactly the same - for example, when rotating, panning, etc.
814
815  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
816    then forces a refresh of the survey pane.  This is intended as a debugging
817    aid - if pressing F5 changes the display at all then there's a missing case
818    where a list should have been invalidated (please report if you find such
819    a case as it is a bug).
820
821  + We now automatically track which OpenGL display lists need to be
822    invalidated on window width or height changes.
823
824  + Increase scale bar maximum width from 65% of the window width to 75% as it
825    was in 1.0.x (except that if that would overlap the clino we now reduce
826    that proportion down until it reaches 50%).  Make the limit of zooming in
827    the same as in 1.0.x.  (ticket#23)
828
829  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
830    the application was fullscreen (the dialog got opened under the main
831    window!)  To work around this, aven would switch out of full screen mode
832    temporarily while showing a dialog.  This case works properly with recent
833    wxGTK, so disable our workaround with versions we know work.  Also, apply
834    the workaround only for wxGTK, not everywhere except on Microsoft Windows
835    as there's no reason to think we need it for other platforms.
836
837  + Grey out the "View North" action when we're already viewing North, and
838    similarly for other compass points.
839
840  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
841    info in the "About" dialog.
842
843  + Fix to set the correct filename on the root of the survey tree - previously
844    the filename of the previous file loaded was used!
845
846  + The movie export code now works with newer versions of the FFmpeg libraries
847    as well as still working with older versions.
848
849  + Fix mixed up messages - the print dialog now says "View" on the left
850    subgroup of controls rather than some unrelated message.
851
852  + On printouts, combine the "Plan View"/"Elevation" info box field with the
853    field which gives the bearing and reduce the height on the info box by the
854    removed field, so it's now 3cm for plans and elevations, as for extended
855    elevations.  Report the tilt angle for tilted elevations which it seems has
856    been missing for ages (it's not in recent 1.0.x either).
857
858  + Tweak the exact positioning of informational text on printouts to look
859    nicer and make better use of the available space.
860
861  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
862    dialog.
863
864  + Make the sign of the tilt angle for printouts consistent with the sign
865    shown by the "clino" in the survey pane.
866
867  + In the "Print" dialog, when in plan view disable the "Plan view" button,
868    and similarly for the "Elevation" button.
869
870  + (Microsoft Windows version): Sort out appearance of custom cursors.
871
872  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
873
874  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
875    you can't get out again easily, so add code to explicitly check for F11
876    being pressed and toggle full screen.
877
878* (Linux version): Fix the RPM .spec file for where man pages now get installed
879  and package aven.svg and the vim support files.  (Fixes from James Begley)
880
881* "make check" now performs several checks on the translation files.
882
883* More messages are now available to be translated.
884
885* cavern: Fix reporting of ranges of survey coordinates, which was broken by
886  the message handling changes in 1.2.0.
887
888* Fix warning when compiling with GCC.
889
890* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
891  sudo for installing on Unix.
892
893* In the manual, replace the instructions for building from source with a
894  pointer to the clearer instructions in INSTALL.
895
896* In the manual, make it clear that installing with administrator rights
897  also applies to newer platforms than XP.
898
899* doc/TODO.htm: Update.
900
901Changes in 1.2.0 (2011-09-20):
902
903* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
904  English.
905
906* tests/smoke.tst: aven no longer requires an X display for --help or
907  --version, so replace skip of this check with a check that this remains the
908  case.
909
910* We now use the standard .po and .pot file formats for storing translations
911  (rather than the Survex-specific messages.txt format), and then translate
912  these into Survex's .msg format.
913
914* (Unix version): Move survex man page to section 7 (since it isn't documenting
915  an actual command).
916
917* (Unix version): Write each generated man page to a temporary file, then
918  atomically rename, to avoid leaving an empty or partial man page behind if
919  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
920  recurrence of that).
921
922* (Unix version): Default to installing docs into /usr/share/doc/survex rather
923  than /usr/doc/survex.
924
925* aven:
926
927  + Fix handling of accented characters in the survey pane.
928
929  + Aven icon redrawn in SVG format - it's now a vector image which looks
930    nicer at larger sizes.
931
932  + Explicitly request double-buffering, which seems to be needed for systems
933    with GLX >= 1.3.
934
935  + Fix crash while trying to load certain .3d files.
936
937  + Movie export code updated to work with more recent versions of FFmpeg.
938    Currently this is disabled in Microsoft Windows builds, pending getting the
939    required libraries set up for building releases.
940
941  + Reporting of errors during movie export improved.
942
943  + Force playback speed to "x1" during movie export.
944
945  + Use stock IDs for buttons where appropriate - such buttons may now be
946    rendered with icons on some platforms.
947
948  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
949    ISO8859-1).
950
951  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
952    as it's no longer required with modern versions.
953
954  + Don't redraw the survey on every mouse movement in the survey pane unless
955    the measuring line is (or just was) active.  (ticket #17)
956
957* cavern:
958
959  + Drop "non-fatal" from the report of how many errors there were at the end
960    of the run - it just confuses users - we won't even get here if there's a
961    fatal error!
962
963  + Add --3d-version option to allow the user to specify the version of the 3d
964    format to output.  (ticket#21)
965
966* img library:
967
968  + Make the highest and lowest valid values for img_output_version available
969    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
970
971* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
972  volume actually gets mounted.  Fix URL for downloading wxWidgets.
973
974Changes in 1.1.16 (2011-05-16):
975
976* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
977  Portuguese, and US English.
978
979* Use horizontal ellipses character rather than '...' and right arrow character
980  rather than '->' where these characters are available.
981
982* (Unix version): Link with -lGL, if it exists, to support linking with gold or
983  GNU ld --as-needed (Debian bug #615781).
984
985* img.c:
986
987  + Fix code typo for IMG_API_VERSION == 0 case.
988
989  + Fix code typo in code used when IMG_HOSTED isn't defined.
990
991* doc/TODO.htm: Remove entries which have now been done.
992
993* (Microsoft Windows version): aven: We now include all the available
994  translations for messages from wxWidgets, which means that standard widgets
995  will appear translated where available even if Survex messages aren't
996  translated.
997
998Changes in 1.1.15 (2010-10-15):
999
1000* aven:
1001
1002  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1003    follow terminology in manual and elsewhere.  Fixes ticket#15.
1004
1005  + When displaying output from cavern, don't update the window after every
1006    line, but only when we don't have data from cavern pending.  Hopefully
1007    addresses ticket#12.
1008
1009  + If we aren't using GL_POINTS for blobs, draw them using a series of
1010    abutting lines rather than with gluDisk which is faster and gives a
1011    consistent shape.
1012
1013  + Check whether blobs and crosses actually render correctly as points/point
1014    sprites, and if they don't, fall back to drawing them with lines.  The
1015    best method is cached on disk, and rechecked automatically if the graphics
1016    hardware is changed or the drivers upgraded.
1017
1018  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1019    though, so we still enable USE_FNT by default).
1020
1021  + Don't offer "All files" wildcard in presentation save dialog.
1022
1023  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1024    more places.
1025
1026  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
1027    when running cavern from aven.  Fixes ticket#11.
1028
1029* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1030
1031* diffpos: Handle files with duplicate labels in better - extend generates
1032  duplicate labels when it breaks a loop.
1033
1034* Enable eswap-break testcase now that diffpos handles duplicate station names.
1035
1036* New v7 of .3d format which stores survey dates as number of days since
1037  January 1st 1900, so we now support dates from 1900-2078 (rather than
1038  1970-2037) with a smaller file size.  The img API is now versioned - you
1039  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1040  gives the survey dates in days in days1 and days2 instead of as time_t
1041  values in date1 and date2.  Fixes ticket#14.
1042
1043* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1044  former has been the canonical name for some time, with www.survex.com just
1045  redirecting to it.
1046
1047* (Unix version): Use unlocked file I/O if available, which can be much faster
1048  in some cases (we don't need the locking as we don't do multithreaded file
1049  I/O).
1050
1051* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1052  headers.
1053
1054* (Mac version): buildmacosx.sh now works again.
1055
1056* Most tests weren't actually running any testcases (looks like a sh
1057  portability issue).  This is now fixed, and fortunately all tests still pass.
1058
1059* Include the extra .isl translation files for Innosetup in the source archive.
1060
1061Changes in 1.1.14 (2010-07-26):
1062
1063* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1064
1065* aven:
1066
1067  + After processing survey data, if there were warnings or errors, add a
1068    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1069    were only warnings, also add an "OK" button to allow moving on to viewing
1070    the processed survey data (fixes ticket#13).
1071
1072  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1073
1074  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1075    not the ': ' after), and to make the title for the terminal the
1076    warning/error message.  Avoid false positives by checking that '<line>' is
1077    a number.
1078
1079  + Don't double escape the contents of href and target in links in the cavern
1080    log window.
1081
1082  + Improve handling of the splitter window, fixing behavioural glitches in
1083    various cases.
1084
1085  + Highlight stations matching any current search when a file is loaded.
1086    (ticket#9)
1087
1088  + (Mac version): Fix build issue due to Mac OS X polluting the global
1089    namespace with its own "Point" class.
1090
1091  + (Unix version): The Gnome print dialog has its own preview window so
1092    suppress ours if using the Gnome one.
1093
1094  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1095
1096  + (Microsoft Windows version): Fix handling of a double-click on the survey
1097    tree when built with wxWidgets >= 2.8.11.
1098
1099* cavern: Report relevant file and line number for three warnings which didn't
1100  give them before.
1101
1102* (Unix and Mac versions): configure: Update the wx-config probing code -
1103  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1104  point looking for them now.
1105
1106* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1107  for easy installation.  Update it to work with the latest Survex versions
1108  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1109  private wxWidgets, use 2.8.11 not 2.7.0-1).
1110
1111* manual:
1112
1113  + Correctly capitalise "GTK".
1114
1115  + Note that on Linux we only regularly test builds with the GTK+ version
1116    (change taken from 1.0).
1117
1118* Fixed the cad3d man page, which was an empty file in 1.1.13.
1119
1120Changes in 1.1.13 (2010-06-16):
1121
1122* Say "wxWidgets" instead of "wxWindows" consistently.
1123
1124* img.c: Fix small memory leak (filename_opened member).
1125
1126* cad3d, aven: Fix export to SVG when a label contains a '%' character.
1127
1128* aven:
1129
1130  + wxWidgets 2.6.0 or newer is now required.
1131
1132  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1133    work but hasn't been tested recently (all packaged versions of wxWidgets
1134    seem to be Unicode now).
1135
1136  + Fix potential uses of uninitialised variables which may have been causing
1137    occasional glitches when loading a file on start-up.
1138
1139  + Improvements to the handling of the font used for plotting labels and other
1140    text on the survey pane:
1141
1142    - Loading the font file is more efficient.
1143
1144    - Character spacing is improved.
1145
1146    - Default font is now anti-aliased.
1147
1148  + "About" dialog:
1149
1150    - Add "Copy" button to copy the system info to the clipboard for easier
1151      bug reporting.
1152
1153    - List OpenGL extensions last, since there are usually lots of them with a
1154      modern gfx card.
1155
1156    - Fix 100% CPU usage while the "About" dialog is open.
1157
1158  + Processing .svx files:
1159
1160    - Passing a .svx file on the command line now works better.
1161
1162    - Put the survey data log window in a splitter in the usual frame rather
1163      than opening a separate frame for it.
1164
1165    - Auto-scroll the log window until we've reported a warning or error.
1166
1167    - Fix small memory leak.
1168
1169  + The presentation filename now defaults to using the basename of the
1170    currently loaded dataset, but we always prompt before we first save with
1171    such a name.
1172
1173  + Reduce memory usage when saving a screenshot.
1174
1175  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1176    persist the window size (and maximised or fullscreen state) between
1177    invocations.
1178
1179  + Fix reporting of OpenGL errors.
1180
1181  + Fix glitches when tilting while looking East.
1182
1183  + Added Portuguese and Slovak translations of wxWidgets messages.
1184
1185* Documentation:
1186
1187  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1188
1189  + Drop the "alternative manual formats" self-extracting zip file - people
1190    will generally just want one of the formats, so downloading several
1191    together isn't very useful.
1192
1193  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1194
1195  + GPL.htm: Replace HTML version of licence with a link to the version on
1196    the FSF website.
1197
1198  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1199    low level to be of interest to non-developers, and developers can look at
1200    the source code.
1201
1202* (Unix version): configure: New preferred name for specifying wx-config script
1203  is WX_CONFIG.  WXCONFIG still supported for compatibility.
1204
1205* (Linux version): Source RPM package dropped as you can just build an RPM
1206  package from the source tarball.
1207
1208* (Microsoft Windows version): The installer is now created with a newer
1209  version of InnoSetup, which gives a 10% smaller download.
1210
1211Changes in 1.1.12 (2007-02-07):
1212
1213* aven:
1214
1215  + Remember the window size or maximised/fullscreen state between invocations.
1216
1217  + Add options dialog to "Export" similar to the one for "Print".
1218
1219  + The "number of pages required" in the print dialog now updates when you
1220    change what is to be shown (underground legs/surface legs/station
1221    names/crosses).
1222
1223Changes in 1.1.11 (2006-11-25):
1224
1225* Updated Czech, Spanish, and Slovak translations.
1226
1227* (MacOS X version): Assorted OS X specific tweaks and fixes.
1228
1229* aven:
1230
1231  + Pick a smaller and clearer font for labels.
1232
1233  + Fix character spacing.
1234
1235  + Tweak display of bearing and elevation angles to look nicer with
1236    proportional fonts.
1237
1238  + Use the title from the 3d (or plt, etc) file for the window title
1239    rather than the filename.
1240
1241  + Show distances to 2 decimal places rather than the nearest integer.
1242
1243  + Only consider underground legs when calculating the depth bands and
1244    depth colouring.
1245
1246  + Add "Colour by Error".
1247
1248  + Add entry for "white" in date and error keys.
1249
1250  + When setting the view to a single point, don't change the scale.
1251
1252  + If reloading the same file, don't change the view
1253
1254  + Fix filetypes selector in open dialog.
1255
1256  + Fix the charset we use for aven in certain cases.
1257
1258  + Call msg_init before using msg_lang or it won't ever be set!
1259
1260  + Pass wx the full language code to initialise the C library locale.
1261
1262  + Fix bug in generating prefix tree view which could lead to a bogus
1263    leading dot on some survey names (bug probably introduced in 1.1.10).
1264
1265  + "New Presentation" now ensures that the side panel is open
1266
1267  + Fix updating of cached opengl lists when the view is reset to the
1268    default.
1269
1270* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1271  LANG which AutoCAD installation seems to set on MS Windows.
1272
1273* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1274  specified.  Either/both can be set to ":".
1275
1276* dump3d: Report unknown (to dump3d) codes returned by img.
1277
1278* img library: Flag all stations as underground in the old "ASCII" .3d format.
1279
1280Changes in 1.1.10 (2006-07-14):
1281
1282* aven: Clicking on a survey name in the survey tree now highlights it in
1283  the map view.  Double-clicking zooms the view to show the clicked survey
1284  highlighted.  Clicking the root clears the highlighting and double-clicking
1285  the root restores the default view.  To expand/collapse a branch, click
1286  on the "[+]" or "[-]" icon to the left of the survey name.
1287
1288* aven: The measuring line can now measure to anywhere in plan or elevation
1289  view (not just to a station!)  In plan view the horizontal distance and
1290  bearing are shown, while in elevation view the vertical distance is shown.
1291
1292* aven: Moving the mouse over a station in the survey view now highlights
1293  that station in the survey tree (though it may not be visible if the
1294  survey(s) it is in aren't expanded).
1295
1296* aven: Clicking on a station to centre the view now moves the mouse pointer
1297  to the new location of the station (except on Mac OS X where this isn't
1298  allowed).
1299
1300* aven: Fix which presentation toolbar buttons are shown as depressed.
1301
1302* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1303
1304* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1305
1306Changes in 1.1.9 (2006-07-04):
1307
1308* (Unix version): Install desktop files for aven and svxedit contributed to the
1309  Ubuntu package by Phil Bull, and corresponding pixmaps.
1310
1311* Fix img to filter out cross-sections which don't match the subsurvey (if
1312  specified).  The API now returns img_XSECT_END to mark the end of a
1313  passage rather than setting a flag on the last img_XSECT of the passage.
1314
1315* Enhance integration with the vim editor - this can now colour .err files, run
1316  cavern from vim and parse error output, and run aven from vim.  Tweak the
1317  existing vim mode for .svx files to fix a few minor bugs and add support for
1318  the new "*data passage" style.
1319
1320* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1321  which can't draw large enough blobs for us.
1322
1323* aven: sort out confusion about what encoding everything is in which means
1324  that the distance measured by the measuring line actually gets displayed
1325  and also fixes problems with empty menu items in non-English locales in
1326  some cases.
1327
1328* aven: redraw grey background after a menu is closed over the aven window
1329  with no survey loaded.
1330
1331* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1332
1333* aven: avoid crash on some machines when opening "About" dialog before having
1334  loaded a survey.
1335
1336* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1337
1338* (Unix version): aven: Fix character set handling of cavern output.
1339
1340* cavern: Report an error if a cross-section is specified for a station which
1341  doesn't exist.
1342
1343* Updated French and Italian translations.
1344
1345* (Unix version): aven: Fix "Can't open message file `en_US' using path
1346  `${prefix}/share/survex'" error.
1347
1348* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1349  (doesn't affect Survex itself, but other applications which use img.c should
1350  update their copy).
1351
1352* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1353  and later are caught by configure, whereas older wx versions are caught when
1354  trying to compile).
1355
1356Changes in 1.1.8 (2006.06.30):
1357
1358* Drop support for building with wxWidgets versions prior to 2.4.0
1359  (which was released on 2003-01-07).
1360
1361* aven: Printing through aven now uses settings from the "[aven]" section
1362  of print.ini, and support for hierarchical sections (using "like=")
1363  has been disabled.
1364
1365* aven: Change mouse actions to be compatible with those in Survex 1.0.
1366  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1367  left drag is now smart about not rotating and zooming at the same
1368  time.
1369
1370* aven: Highlighting stations now happens as you type, and pressing
1371  "Enter" or clicking the "Find" button now pans and zooms to show the
1372  highlighted stations.
1373
1374* aven: Left-clicking away from a station now cancels measuring line.
1375
1376* aven: Setting view to North, South, East, or West is now animated like
1377  the tilt from plan to elevation.
1378
1379* aven: Fix presentation saving to also write "." for decimal points and
1380  presentation loading to accept either "." or ",".
1381
1382* (Unix version): aven: Add text for all toolbar items so that aven
1383  will work with the Gnome desktop preference for displaying toolbars as
1384  icons with text or just text (wxWidgets needs fixing first though).
1385
1386* (Unix version): aven: Remove the ability to detach the menu bar (yell
1387  if you actually used it and I'll restore it!)
1388
1389* aven: Add "all survey files" option to the "open file" dialog.
1390
1391* (MS Windows version): aven: Fix cursor keys to pan survey.
1392
1393* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1394
1395* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1396  run by an unprivileged user.
1397
1398* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1399  installer builder we use) and include new installer translations for
1400  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1401
1402* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1403  translations of messages for wxWidgets (the GUI library we use).
1404
1405* aven: Disable "Highlight exported points" if there aren't any.
1406
1407* Updates to French translation from Michel Bovey.  Also updates to German,
1408  Italian, Catalan, Spanish, and Romanian translations.
1409
1410* (Unix version): test suite: fix smoke test to pass even without X running
1411  (it was meant to but the code had a bug).
1412
1413* aven: Check if OpenGL is available and exit cleanly with a helpful error
1414  if it isn't.
1415
1416* (Unix version): aven: Fix --help and --version to work without a working
1417  X display (provided it's built with wxWidgets 2.5.1 or newer).
1418
1419* aven: Automatically select the presentation tab of the notebook when the user
1420  selects "New Presentation" or "Open Presentation".
1421
1422* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1423  reset to default view as well).
1424
1425* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1426  empty.
1427
1428* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1429  up and down instead of being passed on and moving the survey.
1430
1431* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
1432  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1433  Safari 2.0.3, and InkScape 0.42.
1434
1435* aven: Put a 5mm border around exported SVG files to allow for station markers
1436  and non-zero width lines.
1437
1438* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1439  was turned on.
1440
1441* aven: Actually close the file we're exporting which fixes problems with it
1442  not always being fully written.
1443
1444Changes in 1.1.7 (2005.10.18):
1445
1446* cavern: Add validity checking for dates in *date commands (with feature
1447  test in testsuite).  A date entered as just "year" or "year.month" now
1448  becomes a date range for the relevant period (previously it became a single
1449  date near the middle of that period).
1450
1451* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1452  with MS Windows).
1453
1454* extend: Default output name for a file called input.3d is now input_extend.3d
1455  rather than just extend.3d (which was annoying if you wanted to extend
1456  several surveys in the same directory).
1457
1458* aven: OpenGL 2.0 always includes support for point sprites so rework
1459  our check for them to include that knowledge.
1460
1461* aven: Regenerate depth bar if user switches to/from metric units.
1462
1463* aven: Don't clear the "there" mark just because the mouse pointer has
1464  moved off a station.
1465
1466* aven: When processing a .svx file, put the resultant .3d file in the
1467  same directory (since that's where we then try to load it from).
1468
1469* aven: Fix labelling of date colouring on 32 bit platforms.
1470
1471* aven: If "colour by date" is on and we load a survey with no date info
1472  (or all surveyed on the same date) then set "colour by none".
1473
1474* aven: Make the error dialog modal and remove a signal handler once it
1475  has fired to prevent endless (or seemingly endless) cascades of error
1476  dialogs.
1477
1478* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1479  if a survey file with only one station in is loaded.
1480
1481* aven: Fix problems with indicators disappearing when we're drawing
1482  blobs and/or crosses the slow (but always supported) way.  (Problem
1483  introduced in 1.1.6).
1484
1485* (Unix version): aven: Really stop setting extra toolbar margin when using
1486  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1487  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1488
1489* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1490  we've been compiled with, and which GTK+/Motif version where appropriate.
1491
1492* (Unix version): Fixed build on Fedora Core 3.
1493
1494* documentation: Updates to 3d file format specification from Mike McCombe.
1495
1496Changes in 1.1.6 (2005.10.10):
1497
1498* (MS Windows version): Distribution is about a third smaller than 1.1.5
1499  (mostly because mingwm10.dll is no longer required).
1500
1501* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1502  it, showing cavern's output in a window (with errors and warnings clickable
1503  to load the offending file into an editor), and then loading the resulting
1504  3d file.
1505
1506* aven: Added "Colour by Date" option.
1507
1508* aven: Disable "Colour by Depth" option if there's no elevation variation.
1509
1510* aven: Don't crash if trying to load a survey with no elevation variation.
1511  Instead turn off depth colouring.
1512
1513* aven: Export as HPGL added.
1514
1515* aven: Improved update of mouse coordinates and measuring line (thanks to
1516  Martin Green).
1517
1518* aven: Show the coordinates of either the mouse pointer or the nearest
1519  survey station to it (if there is one near enough).  Showing both was
1520  confusing and meant the status bar overflowed on smaller displays.
1521
1522* aven: When printing an extended elevation, don't show bearing and elevation.
1523
1524* aven: Don't lock "flat" surveys which aren't extended elevations - a
1525  flat survey with LRUD data isn't flat any more!
1526
1527* aven: When we have to draw blobs and crosses the slow way (because the
1528  graphics hardware doesn't support the fast way), draw them so that they
1529  should appear at the correct depth into the 3D scene instead of on top
1530  of everything else.
1531
1532* aven: Make "play presentation backwards" icon green to match the other
1533  presentation icons.
1534
1535* (MS Windows version): aven: Mouse clicks on the survey view now set the
1536  keyboard focus there.
1537
1538* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1539
1540* (MS Windows version): aven: Fix redrawing of measuring line.
1541
1542* cavern: Store dates for img_XSECT.
1543
1544* cavern: Fixed small one-off memory leak if you specify -o more than once.
1545
1546* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1547  language to use for messages.
1548
1549* (MS Windows version): "Print" on a 3d file now prints through aven rather
1550  than the separate printer driver (Unix has done this for some time).
1551
1552* Removed old printer drivers.
1553
1554* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1555  to write a file format version which doesn't support it.
1556
1557Changes in 1.1.5 (2005.09.20):
1558
1559* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1560
1561* aven: Make blobs round like they are in Survex 1.0.
1562
1563* aven: If the graphics drivers don't support drawing blobs using OpenGL
1564  point markers, fall back to drawing filled circles.
1565
1566* aven: If the graphics drivers support it, draw crosses as texture mapped
1567  OpenGL point markers which is much faster.
1568
1569* aven: Cross size increased to match Survex 1.0.
1570
1571* aven: We must update which blobs are displayed if display of surface or
1572  underground legs is toggled.
1573
1574* cavern: Fix handling of a *solve followed by survey data, none of which is
1575  attached to the previous data.
1576
1577* cavern: Fixed "No survey data" error when a *solve is followed by another
1578  *solve (or the implicit solve at the end of processing) with no data between
1579  them.
1580
1581Changes in 1.1.4 (2005.09.19):
1582
1583* aven: Added Aven's icon to the "About" dialog.
1584
1585* aven: Use localised character for the decimal point (e.g. "," in most
1586  continental European countries).
1587
1588* aven: Previously the survey tree would get focus and then take keypresses
1589  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1590  operate on the cave, and transfer the input focus across when we do.
1591
1592* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1593
1594* aven: Speed up intialisation by delaying creation of OpenGL lists until
1595  they're needed.
1596
1597* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1598
1599* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1600
1601* aven: Reworded "Restore Default Settings" as "Restore Default View".
1602
1603* (Unix version): aven: Set sensible default margins for printing and preserve
1604  any margin values the user specifies between runs (previously margins
1605  defaulted to 0 each time aven was run).
1606
1607* Documentation: Document *DATA PASSAGE in the manual.
1608
1609Changes in 1.1.3 (2005.09.07):
1610
1611* (Microsoft Windows version): Fixed build problems.
1612
1613* cavern: Allow OMIT character (-) for left/right/up/down.
1614
1615* aven: Remove an unnecessary menu separator.
1616
1617* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1618
1619* aven: Make the tooltip for "Hide" show the number of found stations.
1620
1621* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1622
1623* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1624  when there's a presentation loaded.
1625
1626* aven: Make entrances green in side panel tree list to match green blobs used
1627  in cave view.
1628
1629* aven: Don't show surface labels if we're not showing surface data, etc.
1630
1631* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1632  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1633  existing users are happy, but don't advertise it.
1634
1635* aven: Normalise filename by adding any extension used, and use the normalised
1636  filename for file history and window title.
1637
1638* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1639  as the toolbar buttons already have a sensible margin - the extra margin is
1640  only needed with GTK1.2.
1641
1642* aven: Fix handling of plumb legs in tube model.
1643
1644* aven: Fixed swapped L and R in tube model.
1645
1646* extend: Preserve UD cross-section information in extended elevation.
1647
1648* extend: Add new messages for John Pybus' enhancements.
1649
1650Changes in 1.1.2 (never formally released):
1651
1652* Added support for LRUD data in .svx files, in .3d files, and aven can
1653  now load and display it on screen and on printouts.  The ability to "fake"
1654  LRUD data in aven is gone for now but will reappear in some form later.
1655
1656* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1657  fold any desirable missing chasm functionality into aven.
1658
1659* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1660  cursors for each different mouse action to help the user learn what each
1661  does.  Also added cursors for the "compass" and "clino" as well as the
1662  scalebar to suggest to the user that they can be dragged to change the view.
1663
1664* (Unix version): aven: Don't segfault if LANG isn't a known language.
1665
1666* tests/smoketest.tst: If X windows is running, check that we can run aven
1667  with --help and --version.
1668
1669* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1670  no results are listed for it.  This revealed that there was a "newline" test
1671  which should have been called "badnewline", and was a broken testcase too!
1672  Fixed all these problems.
1673
1674* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1675  and omitted forward compass/clino readings in Compass DAT files.  Added
1676  a feature test for this to the testsuite.
1677
1678* It no longer makes sense to have an option not to build aven or to build aven
1679  without OpenGL so remove old machinery for this from configure and the
1680  sources.
1681
1682* (Unix version): configure: Check if "-lXxf86vm" is needed.
1683
1684* configure: Better output for strcasecmp test.
1685
1686* aven: Fix crosses to work much better.  Not a total fix - their position
1687  in the Z buffer isn't correct and they're rather slow to plot.
1688
1689* aven: Don't regenerate the hittest grid every time the mouse moves while
1690  animating, which solves the mysterious pausing effect (thanks go to Martin
1691  Green for spotting this!)  Also clear all the status bar coordinates when
1692  animating.
1693
1694* aven: Sort out clashing menu shortcuts in some languages.
1695
1696* aven: Fixed compilation problem on x86_64
1697
1698* SPUD: Pruned out stuff which has been done or which is not actually relevant
1699  to this branch.
1700
1701* Merge various changes from 1.0 branch:
1702
1703  + aven: Port over "printing from aven" functionality.
1704
1705  + aven: Port over "export as" functionality,
1706
1707  + Add David Loeffler's vim mode for .svx files.
1708
1709* aven: Fix check for whether a label is behind us in perspective view.
1710
1711* aven: Don't use an opengl list for drawing the indicators - we typically make
1712  a new list each time we plot them anyway.
1713
1714* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1715
1716* aven: Set icon on non-Windows platforms too.  This means that with
1717  WindowMaker on Unix you get an icon on the AppIcon by default.
1718
1719* configure: Update wxWindows checks to handle newer wx versions.
1720
1721* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
1722  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
1723  for anyone building from CVS).
1724
1725* acinclude.m4: Quote macro name for fix autotools warning.
1726
1727* Documentation: "tilt up" is "'" not ",".
1728
1729* aven: Add support for mousewheels (to tilt the cave).
1730
1731* aven: Fixed twisted transitions to and from pitches in certain cases.
1732
1733* aven: Pick a sensible initial window size when the user's desktop is spread
1734  over more than one monitor (works best with wx2.5 or newer, but try to do
1735  better with wx2.4 or earlier as well).
1736
1737* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
1738  contents being visible before any survey is loaded.
1739
1740* aven: Allow a coloured texture to be used
1741
1742* aven: Don't initialise until we have data (to the user, this means the window
1743  is default colour (grey for most systems) not black until a survey is
1744  loaded).
1745
1746* aven: Fixed weird "shadowed" icons.
1747
1748Changes in 1.1.1 (2004-10-06):
1749
1750* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
1751  startup.
1752
1753* aven: Delay loading the bitmap for the "About" dialog until it is first
1754  needed.  We want start up to be as quick as possible.
1755
1756Changes between 1.0.32 and 1.1.0 (never formally released):
1757
1758* NOTE: Survex 1.1.X releases are development snapshots made available for
1759  the purposes of allowing wider testing and getting more user feedback.  Once
1760  the code has stabilised the version number will be raised to 1.2.0.
1761
1762* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
1763  you're using Windows 95 - these can be obtained from:
1764  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
1765
1766* aven: Solid passages - passage dimensions are currently inferred from
1767  the leg length (pretty effective as you can measure longer legs in
1768  larger passages).  Use of real LRUD data coming soon...
1769
1770* aven: Depth colouring is now continuously varying.
1771
1772* aven: Colour by depth can now be turned off (and there's the start of a
1773  framework for properly implementing colour by date, error, etc).
1774
1775* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
1776  match (? matches any character, * matches any number of characters).
1777
1778* aven: We now use the status bar for coordinates, distances, etc to make
1779  better use of screen space.
1780
1781* aven: Full screen mode (F11).
1782
1783* aven: Perspective view.
1784
1785* aven: Context sensitive cursor shape - needs more work.
1786
1787* aven: Mouse actions changed (hopefully they're now more natural, but
1788  you may find the change disorientating - feedback wanted on this).
1789
1790* aven: Added "presentations" which allow you to set up fly-through paths
1791  and load/save/run them.
1792
1793* aven: A presentation can be exported as a movie file.
1794
1795* aven: Added Save screenshot facility.
1796
1797* aven: Depth fogging option.
1798
1799* aven: Added Smooth Lines option.
1800
1801* aven: Added Textured Walls option.
1802
1803* aven: If a survey has surface legs but no underground legs, default to
1804  showing the surface legs.
1805
1806* cavern: Dates given to *date are now stored in the 3d file.
