[5c676e2]2
[2c5ec88]3Changes in 1.2.14 (2014-06-??):
[5c676e2]4
5* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
6  1.2.13.  (Reported by Brian Clipstone)
7
8* aven: Fix wx assertion failures when showing hit test debug view on platforms
9  such as 64-bit Linux.
10
[2c5ec88]11* aven: When viewing from above, show "Plan" above the "clino" which indicates
12  the tilt angle (instead of "Elevation -90°").
13
[5c676e2]14* aven: The extended font data now loads faster, and also uses less memory on
15  64-bit platforms.
16
[2c5ec88]17* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
18  the space available in the aven UI.
19
20* (Microsoft Windows version): Include dump3d in the installer.
21
[5c676e2]22* Fix a compiler warning.
23
24* Improve test coverage.
25
[0d365be]26Changes in 1.2.13 (2014-05-15):
[acbb5b1]27
[8ccd1d8]28* aven: Fix --print option to wait for printing to happen before exiting
29  (previously it would exit right after opening the print dialog, so you
30  couldn't actually print anything out using it).
31
[acbb5b1]32* aven: Increase the threshold for how close the pointer needs to be to a
33  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
34  Hugh St Lawrence.
35
[0d365be]36* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]37  if increasing the minimum pointer to station threshold helps Hugh's problems
38  with using aven on a touch screen device.
39
[acbb5b1]40* aven: The measuring line was unable to see stations which had just been
41  revealed by toggling surface or underground legs on - this is now fixed.
42
43* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
44  many entries are in each box (toggled by F3).
45
46* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
47  off and back on.
48
49* aven: Create the empty hit-test grid data structure lazily, to reduce start
50  up time a little.
51
52* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
53  and *end commands to instead talk about "survey names".
54
55* cavern: For ages cavern has warned if you reentered a survey, but this
56  warning was suppressed if it occurred at the same line of the same file as
57  the survey was first entered, but this can only happen if you include the
58  same survey file more than once, which isn't a sensible thing to do for a
59  file with actual survey data in (you might reasonably do it to set up survey
60  grade details or something like that).  The warning is now given in this
61  situation too.
62
63* cavern: After 5 warnings about reentering a survey we give up warning about
64  it, but we used to keep reporting where the survey was originally entered -
65  this secondary diagnostic message is now silenced when the main message is.
66
67* (Microsoft Windows version): Compile C code with optimisation on.
68
69* Add the start of a Russian translation, with messages take from therion.
70
71* Minor translation updates to French.
72
73* Fix compiler warning from GCC.
74
75* Testsuite improvements:
76
77  + Test that "..." anon station works.
78
79  + cavern.tst: Check number of errors returned by all testcases which should
80    fail and give an error count.
81
82  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
83
[ad727d8]84Changes in 1.2.12 (2014-04-14):
[46d12e9]85
[63e8642]86* aven: Fix measuring line to show change in altitude rather than altitude
87  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
88  Clipstone.
[46d12e9]89
[ad727d8]90* aven: Fix printing when built with wxWidgets 3.0.
91
92* aven: Several visual improvements to printouts:
93
94  + Move the numbers below the scale bar down a little so that they don't
95    overlap the scale bar ticks.
96
97  + Set the clipping region after we draw the page border and info box to avoid
98    clipping the border in print preview.
99
100  + Tidy up the appearance of the compass and elevation arrow.
101
[63e8642]102* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
103  <http://bugs.debian.org/739332>.
[46d12e9]104
[63e8642]105* aven: Fix to build with older libav where avcodec_free_frame() isn't
106  available.
[46d12e9]107
[ad727d8]108* (Linux version) survex.spec: Update spec file used for building RPM packages.
109
110* (Unix version): Add "Keywords:" entry to .desktop files.
111
112* (Unix version): Enable large file support, mostly to support filing systems
113  which return 64 bit inode values, such as CIFS mounts.
114
[63e8642]115* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
116  rather than any character which is a letter in the current locale.
[46d12e9]117
[63e8642]118* Various translation updates.
[46d12e9]119
[aac3336]120Changes in 1.2.11 (2014-01-28):
[fb941bfd]121
122* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
123  Reported by Kevin Dixon.
124
[aac3336]125* aven: Embed the font data for the first 256 Unicode characters for use in the
126  survey pane into the compiled aven binary to reduce start up overhead.  Any
127  additional characters needed are loaded from a data file only if/when a
128  character >= U+100 is actually needed (as before).
129
[ad3017d]130* aven: Fix display of Unicode characters above 256 when there's a character
131  <= 256 earlier in the same string.
132
[77bdacf]133* aven: Use the actual width of Unicode characters above 256 rather than
134  assuming they are 16 pixels wide.
[ad3017d]135
136* aven: If full screen, don't show the side panel when a new file is opened
137  (e.g. via Ctrl+O).
138
139* aven: Don't give an assertion failure when showing passages for a cave with
140  no vertical extent.  Reported by Jonny Prouty.
141
142* aven: Change terminology in print dialog - say "legend" instead of "info
143  box".
144
145* aven: Add option to show the tilt angle as a percentage gradient.
146
147* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
148  indicators.
149
150* aven: All length units are now translatable.
151
[fb941bfd]152* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
153  will reduce code size and also the number of deprecation warnings about
154  gluErrorString on Mac OS X 10.9.
155
[ad3017d]156* (Microsoft Windows version): aven: Try to work around redraw issues related
157  to the measuring line by redrawing the whole window, which doesn't seem to be
158  measurably slower.
159
160* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
161  give an error rather than quietly ignoring the attempt.
162
[77bdacf]163* cad3d: Make cad3d remap control characters and spaces in station names when
164  generating PLT output in the same way aven does.
165
[ad3017d]166* Various translation updates (particular thanks to Eric Madelaine and Dennis
167  Baudys), including the start of a Bulgarian translation, with messages taken
168  from Therion and elsewhere.
169
170* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
171  GetUserDefaultUILanguage() to get the UI language to use.  For older
172  versions, continue to use GetUserDefaultLCID().
[fb941bfd]173
174* (Microsoft Windows version): The Indonesian translation will now be used
175  automatically when the system language is set to Indonesian.
176
177* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
178  A. Riggs for his work on this.
179
180* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
181  checksum check for the downloaded wx sources.
182
183* Fix a lot of the compiler warnings when building with clang.
184
[ad3017d]185* doc/manual.sgml: Add missing quantities to the list documented as accepted by
186  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
187  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
188  mentioned in list of the units that can be set for them); COUNT (missing
189  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
190  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
191
192* Test suite: Improve test coverage for cavern.
193
[0ecf3b1]194Changes in 1.2.10 (2014-01-15):
195
196* aven: Fix assertion if two mouse buttons are held down at the same time.
197  If dragging with more than one mouse button held down, releasing one causes
198  another which is still held down to take effect.  Reported by Brian
199  Clipstone.
200
[53966d3]201* aven: If we fail to start the external editor when the user clicks on an
202  error or warning from cavern, show an error box.
203
[6f0d0d8]204* aven: If the survey has a title, add it as a top-level <title> element to
205  exported SVG files.
206
207* aven: Escape '<', '>', and '&' in labels in exported SVG files.
208
209* aven: In GPX export, set the <time> element to the datestamp from the 3d
210  file.
211
212* aven: Don't try to write the title if it isn't set or is empty when exporting
213  GPX files.
214
215* aven: Don't bother looking up the printer page setup info when exporting.
216
[0ecf3b1]217* (Microsoft Windows version): aven: Fix crash on "File->Print" or
218  "File->Export" under Windows XP, reported by Brian Clipstone.
219
220* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
221  encoded filename which could occur if run without being asked to load a file
222  on startup.
223
224* (Microsoft Windows version): aven: Compile with optimisation on.
225
226* img library, aven: Although processed CMAP data files are often referred to
227  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
228  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
229  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
230  continue to do so in case anyone is relying on it, but also check for the
231  other extensions.
232
233* img library: Add new "datestamp_numeric" field to struct img giving the
234  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
235  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
236  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
237  timezone wrong.
238
239* img library: Fix my_strcasecmp() to handle top-bit set characters better.
240
[6f0d0d8]241* cavern: Fix NULL pointer dereference when processing Compass DAT file without
242  'SURVEY DATE:'.
[0ecf3b1]243
[6f0d0d8]244* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]245
[6f0d0d8]246* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]247
[53966d3]248* Fix some compiler warnings if built with glibc's fortify source feature
249  enabled.
250
[6b6fb4d]251Changes in 1.2.9 (2014-01-08):
252
253* Document --3d-version in cavern man page and the manual.
254
255* aven: Fix compilation error in movie export code with recent libavi.
256
257* aven: Fix warning on stderr when export a movie as MPEG.
258
259* img library: In non-hosted mode, don't define GETC and PUTC if they're
260  already defined, to allow easy overriding with getc_unlocked() and
261  putc_unlocked() (which are significantly faster on Linux).
262
263* img library: In non-hosted mode, check that int is at least 32 bits,
264  and if not, use long.  In practice, platforms with 16 bit int are mostly
265  obsolete, but it's not hard to be portable here.
266
267* img library: Add test that img.c and img.h compile in non-hosted mode
268  (regression test for issue fixed in 1.2.8).
269
270* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
271
272* Update translations from launchpad and from existing similar messages.
273
274* Fix some compiler warnings.
275
[e1f27c4]276Changes in 1.2.8 (2013-10-29):
[da65891]277
278* cavern: Fix handling of anonymous wall stations ('..' by default) to
279  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
280  Holder.
281
[e1f27c4]282* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]283  statistics when the value gets large.
284
[a4adf09]285* cavern: Eliminate redundant progress message when solving simultaneous
286  equations.
287
[e1f27c4]288* aven: Add a format drop down to the export dialog, and only show fields which
289  are meaningful and supported for the currently selected export format.  The
290  format defaults to that used most recently.  The "Elements" and "View" boxes
291  have been swapped in the print and export dialogs as that layout works much
292  better when the "View" box is hidden.
293
[0056ee1]294* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
295  - now works again.  Reported by Anthony Day.
296
[e1f27c4]297* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
298  this release the projection which the survey coordinates are in defaults
299  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
300  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
301  projection string.  The ability to specify this projection in a better
302  way is coming soon.
303
304* aven: New export options "Origin in centre" and "Full coordinates" - the
305  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
306
307* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
308  time ago, so update references.
309
310* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
311  with wxMSW 2.9.5.  Reported by Brian Clipstone.
312
313* aven: Make right click in an empty presentation mark the current position and
314  open it to edit, instead of crashing.
315
316* aven: Update movie export code to work with latest libav API.  Reported by
317  Sebastian Ramacher.
318
319* aven: Improve reporting of errors during the process of exporting a movie.
320
321* aven: Don't try to close the movie if we aren't producing one.
322
323* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
324
325* aven: Fix to build with wxMSW 2.9.5.
326
327* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
328
329* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
330  ago, so add a new --skencil option to specify this output format.  The old
331  name (--sketch) is still recognised for compatibility.
332
333* cad3d: Make --marker-size work for Skencil and SVG output.
334
335* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]336
[88b54df6]337* img library:
338
[e1f27c4]339  + Fix to work once more when used outside of Survex (missing definition of
340    max() macro and a bad call to free() in img_close() for a file opened for
341    reading).
342
343  + Use lround() instead of round(), and make the tests around whether we use
344    the library function or the our fallback implementation saner.
345
346  + Fix // comments in C code for portability to pre-C99 compilers which don't
347    support these as an extension.
[88b54df6]348
[f807d8bf]349  + Can now be compiled as C++ as well as as C.
350
[e1f27c4]351* (Microsoft Windows version): The installer is now built with a newer version
352  of Innosetup, and includes translations for all the languages which Survex
353  itself has any translations for.
354
355* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
356
357* Minor translation updates.
358
359* tests/Makefile.am: Distribute files for "normal_bad" testcase.
360
[e34bebc]361Changes in 1.2.7 (2013-07-27):
[65d9b6b]362
[e34bebc]363* Add support for anonymous stations, which are indicated by one, two or three
364  separator characters - with the default separator of '.', that means '.',
365  '..', and '...' are anonymous stations.  Single separator ('.' by default)
366  is an anonymous non-wall point, double separator ('..' by default)
367  is an anoymous wall point at the end of an implicit splay), and triple
368  separator ('...' by default) is an anoymous point (with nothing special about
369  the leg).  A new *alias command allows '-' to be mapped to '..' for
370  compatibility with pocket topo: *alias station - ..
[07beaa4]371
[e34bebc]372* New version 8 of the 3d format:
[07beaa4]373
[e34bebc]374  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]375
[e34bebc]376  + New explicit file-wide flag for 'this is an extended elevation', rather
377    than modifying the survey title to indicate this.
[da9d788]378
[e34bebc]379  + The survey prefix is often unchanged from one leg to the next, so use a
380    spare flag to compactly indicate when there's no label change.
[da9d788]381
[e34bebc]382  + The data style of each leg is now stored.
[da9d788]383
[e34bebc]384  + The "processed at" time is stored as seconds since 1970 rather than a
385    human-readable string.
[da9d788]386
[e34bebc]387  + Since 3d v8 features significant changes to the format, the format
388    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]389
[e34bebc]390* img library:
[da9d788]391
[e34bebc]392  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]393
[e34bebc]394  + Handle .pos files containing unnamed stations - don't suck the next line in
395    as the station name, and set img_SFLAG_ANON for them.
[da9d788]396
[e34bebc]397  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
398    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
399    elevation, in place of appending " (extended)" to the title.  Internally we
400    still append this to the title (and remove it upon reading) when writing
401    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
402    explicitly in the file.
[da9d788]403
[e34bebc]404  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]405
[e34bebc]406* aven:
[da9d788]407
[e34bebc]408  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
409    now, and the wx developers consider even 2.8 to be rather long in the
410    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
411    formally dropping support for older versions allows a number of workarounds
412    to be removed from the aven source code.  Also, features deprecated in
413    wxWidgets 2.9 are no longer used in our code.
[da9d788]414
[e34bebc]415  + Don't run incremental search on every key-press, as on a slow machine the
416    short initial search(es) will take a while but not be useful.  Instead only
417    actually run the search when we're told there are no more key-presses
418    queued up.
[da9d788]419
[e34bebc]420  + Implement support for including cross-section information in exported SVG
421    and DXF files (ticket#4).  The DXF export is untested currently.
422
423  + Show splay legs faded by default, with menu options to hide them or show
424    them like other legs.
425
426  + Speed up loading a .3d file with cross-sections by using a map to convert
427    station names to positions.
428
429  + In the cavern log window, don't highlight a file:linenumber if there's no
430    message after it, which avoids highlighting the "Included from" lines
431    wrongly.
432
433  + Fix not to crash when trying to report an error while starting up.
434
435  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
436    the OS X standard shortcut Shift-Command-F (previously we used F11, but
437    that's used by the desktop).
438
439  + Add checks for errors when reading the font file.
[07beaa4]440
[e34bebc]441  + Remove useless extra quoting when invoking vim to show the location of an
442    error from cavern.
[07beaa4]443
[e34bebc]444  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]445
[e34bebc]446  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
447    in the dialog in sync.
[da9d788]448
[e34bebc]449* cavern:
[3dfffa2]450
[e34bebc]451  + Demote errors about invalid dates to warnings, since we've accepted *date
452    for ages without any checks on the value, and so existing datasets
453    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]454
[e34bebc]455  + New *alias command allows '-' to be mapped to '..' for compatibility with
456    pocket topo: *alias station - ..
[07beaa4]457
[e34bebc]458  + We want to warn if there's a clino reading which it would be impossible to
459    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
460    read "93" (it's probably a typo e.g. for "39").  However, the gradient
461    reading from a topofil is typically in the range 0 to 180, with 90 being
462    horizontal.  Really we should allow the valid range to be explicitly
463    specified, but for now we infer it from the zero error - if this is within
464    45 degrees of 90 then we assume the instrument can read between 0 and 180
465    degrees.
[da9d788]466
[e34bebc]467  + If the survey isn't all connected, still run survey tree checks and report
468    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
469    Dixon for the report which highlighted this issue.
[da9d788]470
[e34bebc]471  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]472
[e34bebc]473  + Report column numbers as well as line numbers for some cavern errors and
474    warnings.
[07beaa4]475
[e34bebc]476  + Adjust width of node stats table to fit longest count when there are more
477    than 9999 of a particular order of node.
[07beaa4]478
[e34bebc]479  + If the argument to *include has an opening double quote but the closing
480    double quote is missing, then skip trying to open the file.
[da9d788]481
[e34bebc]482  + Move "Station X referred to just once" warning after non-existent survey
483    check - if both fire, the non-existent survey error is likely to be more
484    relevant.
[da9d788]485
[e34bebc]486  + We no longer follow an error for a bad reading in passage data with a bogus
487    "End of line not blank" error, but instead check the remaining readings on
488    the same line.
[da9d788]489
[e34bebc]490  + We no longer follow an error about OMIT for a required reading with a bogus
491    "End of line not blank" error.
[7f6250a]492
[e34bebc]493  + Report an error if the scale factor in *calibrate is zero - it doesn't make
494    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]495
[e34bebc]496  + Report the parent include files starting from the outermost, as that's more
497    logical when there are multiple levels involved.
[07beaa4]498
[e34bebc]499  + If we were expecting a numeric field and instead get something which starts
500    with '+', '-', or '.' but which isn't a number, then fix the error to
501    include that character in the token reported.
[3dfffa2]502
[e34bebc]503  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
504    first item.
[07beaa4]505
[e34bebc]506* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]507
[e34bebc]508* dump3d:
[07beaa4]509
[e34bebc]510  + Build, install and package dump3d as standard - it's useful for grabbing
511    info from 3d files in scripts.
[07beaa4]512
[e34bebc]513  + Add --show-dates option.
[07beaa4]514
[e34bebc]515  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]516
[e34bebc]517  + Report the data style of legs.
[da9d788]518
[e34bebc]519  + Report if the file is an extended elevation.
520
521  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]522
523* Test suite:
524
525  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
526    expected output so it passes reliably.
527
[e34bebc]528  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
529    'Deleted' stations upon failure are the more natural way round.
530
[07beaa4]531  + Add more testcases, expand some existing testcases, and add expected output
532    for more.
533
[e34bebc]534* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
535  appropriate C and C++ compilers to use, and link mingw build statically to
536  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]537
538* (Unix version): When determining the character set for command-line tools,
539  check environmental variable LANG after LC_ALL and LC_CTYPE.
540
541* When determining the language, check environmental variable LC_ALL before
542  LC_MESSAGES and LANG (but after SURVEXLANG).
543
[e34bebc]544* If we don't find the message file, only give an error if it was specified
[665183c]545  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]546  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
547  settings.
548
549* There are a handful of hard-coded English message strings for reporting
550  errors trying loading message files, etc.  These are all now ASCII, as if we
551  fail trying to open a message file, it's more likely the encoding isn't
552  set correctly.
553
554* Prune strings we are no longer using and are probably unlikely to use again
555  into a new file po_codes_dead, so that translators don't get presented with
556  them to translate.
557
[07beaa4]558* Merge lots of translation updates.  Most translations are now complete or
559  close to complete.
[3dfffa2]560
561* Add start of Indonesian translation from Arief Setiadi Wibowo.
562
[07beaa4]563* Fix various compiler warnings when building from source.
564
[e34bebc]565* Include scripts gdtconvert and gen_img2aven in the source distribution.
566
[c575465]567Changes in 1.2.6 (2012-02-23):
[b081031]568
569* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
570
571* (Microsoft Windows version): Include JPEG images for aven in the installer
572  package (ticket#35).
573
574* cavern: If we have a reference to a station in a non-existent survey, give a
575  helpful error rather than saying the station hasn't been exported from the
576  survey.  (Bug reported by Martin Green via email)
577
578* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
579  Kahler.
580
581* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]582  .gpx file with waypoints for entrances.  This needs libproj so is disabled
583  by default for this release - to enable it install the development stuff for
584  libproj and build survex with:
585
586      make FINDENTRANCES=findentrances
587      make install FINDENTRANCES=findentrances
[b081031]588
589* dump3d: Add support for showing img_ERROR_INFO items.
590
591* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
592
593* Incorporate a French translation from launchpad I'd previously copied the
594  English version of by mistake.  Attempt to correct mistranslation of "survey
595  file".
596
[685116f]597Changes in 1.2.5 (2012-01-03):
598
599* aven:
600
601  + The survey tree in the left panel is now in sorted order once more.
602
603  + No longer fails with an assertion if used for a long time (we were leaking
604    an OpenGL list each time one had to be regenerated).
605
606  + Now builds with newer FFmpeg library.
607
608  + Draw measuring line in front of the indicators rather than behind them.
609
610  + Loading a new file (or reloading the current one) no longer invalidates
611    the OpenGL lists for the compass and clino, so will be a fraction faster.
612
613* Improve handling of attempts to look up translated messages before the
614  message subsystem is fully initialised (which only happens if there's an
615  error early on).
616
617* Improve the survex(7) man page text, and fix it to be marked as section 7 in
618  the man page source as well as in the filename.
619
[f15ca67f]620Changes in 1.2.4 (2012-01-01):
621
622* aven:
623
624  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
625    initialised, which doesn't cause problems in some machines, but causes aven
626    to abort on others.  This is now fixed, and there's a check in place to
627    help avoid similar issues in future. (ticket#34)
628
629  + Always use metres or feet for the depth colour key, and chose a consistent
630    precision by looking at the depth range. (ticket#30)
631
632  + Show the depth units below the colour bar rather than after every value.
633
634  + When zooming way in, stay in metres rather than switching to cm.
635
636  + On the scale bar, say “1 mile” rather than “1 miles”.
637
638* Translation updates for Catalan, French and Slovak.
639
[5b9942e]640Changes in 1.2.3 (2011-12-31):
641
642* Fix to build with wxWidgets 2.9.2.
643
644* (Mac OS X version):
645
646  + Processing .svx files from aven now works.
647
648  + Remove spurious blank lines from the licence text in "Get Info".
649
650  + Don't create the help menu at all, as it is empty (because the "About"
651    entry goes elsewhere) and sometimes seems to appear in the UI.
652
653  + INSTALL.OSX: Update to reflect current status.
654
655* aven:
656
657  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
658
659  + Improvements to text plotted on the survey pane:
660
661    - Support plotting Unicode character points > 256 by lazily loading the
662      data for them from the font file and plotting them with a direct call to
663      glBitmap(), which is slower but doesn't require a display list per
664      character.
665
666    - Adjust the spacing from fixed width to putting a one pixel gap either
667      side of each one character (so two between adjacent glyphs).  Mostly this
668      reduces the horizontal width, but it adds a pixel for characters like "m"
669      and two in a few cases.
670
671    - Fix .pixelfont file generation to correctly handle characters wider than
672      8 pixels.
673
674  + Fix expected cross shape so don't always reject using texture mapping to
675    draw crosses.
676
[3ea0178]677  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
678    as those consisting of just one.  Previously we would trip over the empty
679    tube later.  Such tubes can for example be created by extend if a splay shot
680    is the start or end of a tube.
681
[5b9942e]682  + Make the green colour used for entrances in the survey tree the same
683    (slightly darker than before) green used for the entrance blobs.
684
685  + Report the version of the library we're actually running with if built
686    against wx >= 2.9.2.  Make it clear that the version reported is the
687    version *built* with for wx < 2.9.2.
688
[3ea0178]689* extend:
690
691  + Copy the end markers for passage tubes.
[5b9942e]692
[3ea0178]693  + Preserve left and right data for tubes (previously they were set to -1.0
694    which means "no info").
695
696* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
697  was no longer used - it certainly is!
698
699* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
700  messages, and curly single right quote instead of straight ASCII apostrophe.
701  Fall back to using straight ASCII versions if we can't represent them in the
702  current character set.
[5b9942e]703
[3ea0178]704* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]705
706* Test suite:
707
708  + Add test coverage for interleaved diving data.
709
710  + Add testcase for diving data with topofil-style distance.
711
[94960ad]712Changes in 1.2.2 (2011-10-06):
713
714* aven:
715
716  + Replace the textured-mapped font drawing with an approach based on
717    glBitmap.  This doesn't suffer from the character alignment issues which
718    the textured-mapped fonts had, and is actually significantly faster on some
719    machines.  The current font used is (mostly) fixed-width, but this isn't an
720    inherent limitation - it was just the easiest font data to convert to a
721    usable format.
722
723  + Fix assertion failure due to rounding differences on loading certain .3d
724    files.  (ticket#26)
725
726  + Fix assertion failure when turning on 3D passages if they stick out higher
727    or lower than any station.  (ticket#29)
728
[53f8a93]729  + Fix grid not to disappear when blobs are turned on and blobs are drawn
730    using lines.
731
[94960ad]732  + If a degree sign isn't available in the character set in use, transliterate
733    it to 'dg' rather than skipping it.
734
735  + Fix message which should have been a degree sign but got lost in the format
736    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
737    that bearings in the status bar now have a degree sign after them if they
738    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
739
740  + Fix print dialog to calculate the scale required for "One page" right
741    before it calculates how many pages are required, so we don't end up
742    something other than 1x1 being shown when the user changes settings.
743
744  + Update the calculations for picking a scale and for deciding how many
745    pages are needed to take into account the change in info box height made
746    in 1.2.1.
747
[9704252]748Changes in 1.2.1 (2011-10-04):
[e3c58c3]749
750* Translation updates for US English.
751
752* aven:
753
754  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
755    it now shows colours for dates and errors as well as depths.
756
757  + In the colour key for "colour by date", change "No info" to "Undated".
758
759  + Remove the dark grey background from the colour key and just put a single
760    pixel black border around the colours.  This is more in keeping with the
761    other controls, and means the colours are now on a black background so more
762    visually similar to the survey legs.
763
764  + Move the colour key's "Undated"/"Not in loop" entry down a little to
765    improve the appearance.  Make each section a pixel taller.
766
[9704252]767  + Allow "Colour by X" to be selected even if there's no data for X or only a
768    single value of X used (the colour key is much smaller in these cases, and
769    does still provide some useful information).
770
771  + Fix incorrect calculation of depth colouring for survey legs which straddle
772    a depth band boundary.
[e3c58c3]773
774  + The scale bar, compass, clino, and colour key now all have right click
[9704252]775    menus which allow related actions to be performed (especially handy in
776    full-screen mode).
[e3c58c3]777
778  + Improve the font used on the survey pane - it now contains the '-'
779    character (so the clino now shows negative angles as negative, and dates
780    in the colour key are now hyphenated).  Also the spacing and alignment
781    are a little better, though still not perfect.
782
783  + PLT file export now handles spaces and control characters in station names
784    by escaping them with '%' as in URLs.
785
786  + Pressing "Enter" on a station in the tree control now centres the view on
787    that station.
788
789  + The scale bar is now cached in an OpenGL display list since it often gets
790    redrawn exactly the same - for example, when rotating, panning, etc.
791
792  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
793    then forces a refresh of the survey pane.  This is intended as a debugging
794    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]795    where a list should have been invalidated (please report if you find such
796    a case as it is a bug).
[e3c58c3]797
[9704252]798  + We now automatically track which OpenGL display lists need to be
799    invalidated on window width or height changes.
[e3c58c3]800
801  + Increase scale bar maximum width from 65% of the window width to 75% as it
802    was in 1.0.x (except that if that would overlap the clino we now reduce
803    that proportion down until it reaches 50%).  Make the limit of zooming in
804    the same as in 1.0.x.  (ticket#23)
805
[9704252]806  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
807    the application was fullscreen (the dialog got opened under the main
808    window!)  To work around this, aven would switch out of full screen mode
809    temporarily while showing a dialog.  This case works properly with recent
810    wxGTK, so disable our workaround with versions we know work.  Also, apply
811    the workaround only for wxGTK, not everywhere except on Microsoft Windows
812    as there's no reason to think we need it for other platforms.
[e3c58c3]813
814  + Grey out the "View North" action when we're already viewing North, and
815    similarly for other compass points.
816
817  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
818    info in the "About" dialog.
819
820  + Fix to set the correct filename on the root of the survey tree - previously
821    the filename of the previous file loaded was used!
822
823  + The movie export code now works with newer versions of the FFmpeg libraries
824    as well as still working with older versions.
825
826  + Fix mixed up messages - the print dialog now says "View" on the left
827    subgroup of controls rather than some unrelated message.
828
829  + On printouts, combine the "Plan View"/"Elevation" info box field with the
830    field which gives the bearing and reduce the height on the info box by the
831    removed field, so it's now 3cm for plans and elevations, as for extended
832    elevations.  Report the tilt angle for tilted elevations which it seems has
833    been missing for ages (it's not in recent 1.0.x either).
834
835  + Tweak the exact positioning of informational text on printouts to look
836    nicer and make better use of the available space.
837
838  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
839    dialog.
840
841  + Make the sign of the tilt angle for printouts consistent with the sign
842    shown by the "clino" in the survey pane.
843
844  + In the "Print" dialog, when in plan view disable the "Plan view" button,
845    and similarly for the "Elevation" button.
846
[9704252]847  + (Microsoft Windows version): Sort out appearance of custom cursors.
848
[e3c58c3]849  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
850
851  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
852    you can't get out again easily, so add code to explicitly check for F11
853    being pressed and toggle full screen.
854
855* (Linux version): Fix the RPM .spec file for where man pages now get installed
856  and package aven.svg and the vim support files.  (Fixes from James Begley)
857
858* "make check" now performs several checks on the translation files.
859
860* More messages are now available to be translated.
861
862* cavern: Fix reporting of ranges of survey coordinates, which was broken by
863  the message handling changes in 1.2.0.
864
865* Fix warning when compiling with GCC.
866
867* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
868  sudo for installing on Unix.
869
870* In the manual, replace the instructions for building from source with a
871  pointer to the clearer instructions in INSTALL.
872
873* In the manual, make it clear that installing with administrator rights
874  also applies to newer platforms than XP.
875
876* doc/TODO.htm: Update.
877
[120c1c6]878Changes in 1.2.0 (2011-09-20):
[b4ac7007]879
880* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
881  English.
882
[9cfcb3f]883* tests/smoke.tst: aven no longer requires an X display for --help or
884  --version, so replace skip of this check with a check that this remains the
885  case.
886
887* We now use the standard .po and .pot file formats for storing translations
888  (rather than the Survex-specific messages.txt format), and then translate
889  these into Survex's .msg format.
890
[b4ac7007]891* (Unix version): Move survex man page to section 7 (since it isn't documenting
892  an actual command).
893
[9cfcb3f]894* (Unix version): Write each generated man page to a temporary file, then
895  atomically rename, to avoid leaving an empty or partial man page behind if
896  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
897  recurrence of that).
898
[b4ac7007]899* (Unix version): Default to installing docs into /usr/share/doc/survex rather
900  than /usr/doc/survex.
901
902* aven:
903
[120c1c6]904  + Fix handling of accented characters in the survey pane.
905
[9cfcb3f]906  + Aven icon redrawn in SVG format - it's now a vector image which looks
907    nicer at larger sizes.
908
[b4ac7007]909  + Explicitly request double-buffering, which seems to be needed for systems
910    with GLX >= 1.3.
911
912  + Fix crash while trying to load certain .3d files.
913
914  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]915    Currently this is disabled in Microsoft Windows builds, pending getting the
916    required libraries set up for building releases.
[b4ac7007]917
918  + Reporting of errors during movie export improved.
919
920  + Force playback speed to "x1" during movie export.
921
922  + Use stock IDs for buttons where appropriate - such buttons may now be
923    rendered with icons on some platforms.
924
[9cfcb3f]925  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
926    ISO8859-1).
927
928  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
929    as it's no longer required with modern versions.
930
931  + Don't redraw the survey on every mouse movement in the survey pane unless
932    the measuring line is (or just was) active.  (ticket #17)
933
[b4ac7007]934* cavern:
935
936  + Drop "non-fatal" from the report of how many errors there were at the end
937    of the run - it just confuses users - we won't even get here if there's a
938    fatal error!
939
[9cfcb3f]940  + Add --3d-version option to allow the user to specify the version of the 3d
941    format to output.  (ticket#21)
942
943* img library:
944
945  + Make the highest and lowest valid values for img_output_version available
946    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
947
[b4ac7007]948* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]949  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]950
[8f9b0b6d]951Changes in 1.1.16 (2011-05-16):
[ecdb631]952
953* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
954  Portuguese, and US English.
955
956* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]957  rather than '->' where these characters are available.
[ecdb631]958
959* (Unix version): Link with -lGL, if it exists, to support linking with gold or
960  GNU ld --as-needed (Debian bug #615781).
961
962* img.c:
963
964  + Fix code typo for IMG_API_VERSION == 0 case.
965
966  + Fix code typo in code used when IMG_HOSTED isn't defined.
967
968* doc/TODO.htm: Remove entries which have now been done.
969
[8f9b0b6d]970* (Microsoft Windows version): aven: We now include all the available
971  translations for messages from wxWidgets, which means that standard widgets
972  will appear translated where available even if Survex messages aren't
973  translated.
974
[f5e3521]975Changes in 1.1.15 (2010-10-15):
[2d16e4e]976
977* aven:
978
979  + In the cavern log window, change the "Rerun" button to "Reprocess" to
980    follow terminology in manual and elsewhere.  Fixes ticket#15.
981
982  + When displaying output from cavern, don't update the window after every
983    line, but only when we don't have data from cavern pending.  Hopefully
984    addresses ticket#12.
985
986  + If we aren't using GL_POINTS for blobs, draw them using a series of
987    abutting lines rather than with gluDisk which is faster and gives a
988    consistent shape.
989
990  + Check whether blobs and crosses actually render correctly as points/point
991    sprites, and if they don't, fall back to drawing them with lines.  The
992    best method is cached on disk, and rechecked automatically if the graphics
993    hardware is changed or the drivers upgraded.
994
995  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
996    though, so we still enable USE_FNT by default).
997
998  + Don't offer "All files" wildcard in presentation save dialog.
999
1000  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1001    more places.
1002
1003  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1004    when running cavern from aven.  Fixes ticket#11.
1005
1006* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1007
1008* diffpos: Handle files with duplicate labels in better - extend generates
1009  duplicate labels when it breaks a loop.
1010
1011* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1012
1013* New v7 of .3d format which stores survey dates as number of days since
1014  January 1st 1900, so we now support dates from 1900-2078 (rather than
1015  1970-2037) with a smaller file size.  The img API is now versioned - you
1016  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1017  gives the survey dates in days in days1 and days2 instead of as time_t
1018  values in date1 and date2.  Fixes ticket#14.
1019
1020* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1021  former has been the canonical name for some time, with www.survex.com just
1022  redirecting to it.
1023
1024* (Unix version): Use unlocked file I/O if available, which can be much faster
1025  in some cases (we don't need the locking as we don't do multithreaded file
1026  I/O).
1027
1028* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1029  headers.
1030
1031* (Mac version): buildmacosx.sh now works again.
1032
1033* Most tests weren't actually running any testcases (looks like a sh
1034  portability issue).  This is now fixed, and fortunately all tests still pass.
1035
1036* Include the extra .isl translation files for Innosetup in the source archive.
1037
[f9473ab]1038Changes in 1.1.14 (2010-07-26):
1039
1040* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1041
1042* aven:
1043
1044  + After processing survey data, if there were warnings or errors, add a
1045    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1046    were only warnings, also add an "OK" button to allow moving on to viewing
1047    the processed survey data (fixes ticket#13).
1048
1049  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1050
1051  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1052    not the ': ' after), and to make the title for the terminal the
1053    warning/error message.  Avoid false positives by checking that '<line>' is
1054    a number.
1055
1056  + Don't double escape the contents of href and target in links in the cavern
1057    log window.
1058
1059  + Improve handling of the splitter window, fixing behavioural glitches in
1060    various cases.
1061
1062  + Highlight stations matching any current search when a file is loaded.
1063    (ticket#9)
1064
1065  + (Mac version): Fix build issue due to Mac OS X polluting the global
1066    namespace with its own "Point" class.
1067
1068  + (Unix version): The Gnome print dialog has its own preview window so
1069    suppress ours if using the Gnome one.
1070
1071  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1072
1073  + (Microsoft Windows version): Fix handling of a double-click on the survey
1074    tree when built with wxWidgets >= 2.8.11.
1075
1076* cavern: Report relevant file and line number for three warnings which didn't
1077  give them before.
1078
1079* (Unix and Mac versions): configure: Update the wx-config probing code -
1080  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1081  point looking for them now.
1082
1083* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1084  for easy installation.  Update it to work with the latest Survex versions
1085  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1086  private wxWidgets, use 2.8.11 not 2.7.0-1).
1087
1088* manual:
1089
1090  + Correctly capitalise "GTK".
1091
1092  + Note that on Linux we only regularly test builds with the GTK+ version
1093    (change taken from 1.0).
1094
1095* Fixed the cad3d man page, which was an empty file in 1.1.13.
1096
[0bd49eb]1097Changes in 1.1.13 (2010-06-16):
[90d0d71]1098
1099* Say "wxWidgets" instead of "wxWindows" consistently.
1100
[739b92c]1101* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1102
1103* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1104
1105* aven:
1106
[90d0d71]1107  + wxWidgets 2.6.0 or newer is now required.
1108
1109  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1110    work but hasn't been tested recently (all packaged versions of wxWidgets
1111    seem to be Unicode now).
1112
1113  + Fix potential uses of uninitialised variables which may have been causing
1114    occasional glitches when loading a file on start-up.
1115
[e4bfd2f]1116  + Improvements to the handling of the font used for plotting labels and other
1117    text on the survey pane:
1118
1119    - Loading the font file is more efficient.
1120
1121    - Character spacing is improved.
1122
1123    - Default font is now anti-aliased.
[90d0d71]1124
1125  + "About" dialog:
1126
1127    - Add "Copy" button to copy the system info to the clipboard for easier
1128      bug reporting.
1129
1130    - List OpenGL extensions last, since there are usually lots of them with a
1131      modern gfx card.
1132
1133    - Fix 100% CPU usage while the "About" dialog is open.
1134
1135  + Processing .svx files:
1136
1137    - Passing a .svx file on the command line now works better.
[1324d6c]1138
[739b92c]1139    - Put the survey data log window in a splitter in the usual frame rather
1140      than opening a separate frame for it.
1141
[90d0d71]1142    - Auto-scroll the log window until we've reported a warning or error.
1143
1144    - Fix small memory leak.
1145
1146  + The presentation filename now defaults to using the basename of the
1147    currently loaded dataset, but we always prompt before we first save with
1148    such a name.
1149
1150  + Reduce memory usage when saving a screenshot.
1151
[e4bfd2f]1152  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1153    persist the window size (and maximised or fullscreen state) between
1154    invocations.
1155
[90d0d71]1156  + Fix reporting of OpenGL errors.
1157
1158  + Fix glitches when tilting while looking East.
1159
[739b92c]1160  + Added Portuguese and Slovak translations of wxWidgets messages.
1161
[90d0d71]1162* Documentation:
1163
[e4bfd2f]1164  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1165
1166  + Drop the "alternative manual formats" self-extracting zip file - people
1167    will generally just want one of the formats, so downloading several
1168    together isn't very useful.
1169
[90d0d71]1170  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1171
1172  + GPL.htm: Replace HTML version of licence with a link to the version on
1173    the FSF website.
1174
1175  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1176    low level to be of interest to non-developers, and developers can look at
1177    the source code.
1178
1179* (Unix version): configure: New preferred name for specifying wx-config script
1180  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1181
[e4bfd2f]1182* (Linux version): Source RPM package dropped as you can just build an RPM
1183  package from the source tarball.
1184
[739b92c]1185* (Microsoft Windows version): The installer is now created with a newer
1186  version of InnoSetup, which gives a 10% smaller download.
1187
[2e12f8c]1188Changes in 1.1.12 (2007-02-07):
[5940815]1189
1190* aven:
1191
[3db0798]1192  + Remember the window size or maximised/fullscreen state between invocations.
1193
[5940815]1194  + Add options dialog to "Export" similar to the one for "Print".
1195
[6b2113d]1196  + The "number of pages required" in the print dialog now updates when you
1197    change what is to be shown (underground legs/surface legs/station
1198    names/crosses).
1199
[920b066]1200Changes in 1.1.11 (2006-11-25):
1201
1202* Updated Czech, Spanish, and Slovak translations.
1203
[99d8798]1204* (MacOS X version): Assorted OS X specific tweaks and fixes.
1205
[920b066]1206* aven:
[78c67a6]1207
[920b066]1208  + Pick a smaller and clearer font for labels.
[99d8798]1209
[920b066]1210  + Fix character spacing.
[99d8798]1211
[920b066]1212  + Tweak display of bearing and elevation angles to look nicer with
1213    proportional fonts.
[99d8798]1214
[920b066]1215  + Use the title from the 3d (or plt, etc) file for the window title
1216    rather than the filename.
[99d8798]1217
[920b066]1218  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1219
[920b066]1220  + Only consider underground legs when calculating the depth bands and
1221    depth colouring.
[99d8798]1222
[920b066]1223  + Add "Colour by Error".
[99d8798]1224
[920b066]1225  + Add entry for "white" in date and error keys.
[99d8798]1226
[920b066]1227  + When setting the view to a single point, don't change the scale.
[99d8798]1228
[920b066]1229  + If reloading the same file, don't change the view
[99d8798]1230
[920b066]1231  + Fix filetypes selector in open dialog.
[99d8798]1232
[920b066]1233  + Fix the charset we use for aven in certain cases.
[99d8798]1234
[920b066]1235  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1236
[920b066]1237  + Pass wx the full language code to initialise the C library locale.
[99d8798]1238
[920b066]1239  + Fix bug in generating prefix tree view which could lead to a bogus
1240    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1241
[920b066]1242  + "New Presentation" now ensures that the side panel is open
[99d8798]1243
[920b066]1244  + Fix updating of cached opengl lists when the view is reset to the
1245    default.
[99d8798]1246
[920b066]1247* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1248  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1249
[920b066]1250* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1251  specified.  Either/both can be set to ":".
[99d8798]1252
[920b066]1253* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1254
[920b066]1255* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1256
[920b066]1257Changes in 1.1.10 (2006-07-14):
[ac3f376]1258
1259* aven: Clicking on a survey name in the survey tree now highlights it in
1260  the map view.  Double-clicking zooms the view to show the clicked survey
1261  highlighted.  Clicking the root clears the highlighting and double-clicking
1262  the root restores the default view.  To expand/collapse a branch, click
1263  on the "[+]" or "[-]" icon to the left of the survey name.
1264
1265* aven: The measuring line can now measure to anywhere in plan or elevation
1266  view (not just to a station!)  In plan view the horizontal distance and
1267  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1268
[ac3f376]1269* aven: Moving the mouse over a station in the survey view now highlights
1270  that station in the survey tree (though it may not be visible if the
1271  survey(s) it is in aren't expanded).
1272
1273* aven: Clicking on a station to centre the view now moves the mouse pointer
1274  to the new location of the station (except on Mac OS X where this isn't
1275  allowed).
1276
1277* aven: Fix which presentation toolbar buttons are shown as depressed.
1278
1279* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1280
1281* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1282
[920b066]1283Changes in 1.1.9 (2006-07-04):
[6a2594be]1284
1285* (Unix version): Install desktop files for aven and svxedit contributed to the
1286  Ubuntu package by Phil Bull, and corresponding pixmaps.
1287
1288* Fix img to filter out cross-sections which don't match the subsurvey (if
1289  specified).  The API now returns img_XSECT_END to mark the end of a
1290  passage rather than setting a flag on the last img_XSECT of the passage.
1291
1292* Enhance integration with the vim editor - this can now colour .err files, run
1293  cavern from vim and parse error output, and run aven from vim.  Tweak the
1294  existing vim mode for .svx files to fix a few minor bugs and add support for
1295  the new "*data passage" style.
1296
1297* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1298  which can't draw large enough blobs for us.
1299
1300* aven: sort out confusion about what encoding everything is in which means
1301  that the distance measured by the measuring line actually gets displayed
1302  and also fixes problems with empty menu items in non-English locales in
1303  some cases.
1304
1305* aven: redraw grey background after a menu is closed over the aven window
1306  with no survey loaded.
1307
1308* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1309
1310* aven: avoid crash on some machines when opening "About" dialog before having
1311  loaded a survey.
1312
1313* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1314
1315* (Unix version): aven: Fix character set handling of cavern output.
1316
1317* cavern: Report an error if a cross-section is specified for a station which
1318  doesn't exist.
1319
1320* Updated French and Italian translations.
1321
1322* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1323  `${prefix}/share/survex'" error.
1324
[6a2594be]1325* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1326  (doesn't affect Survex itself, but other applications which use img.c should
1327  update their copy).
1328
1329* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1330  and later are caught by configure, whereas older wx versions are caught when
1331  trying to compile).
1332
[920b066]1333Changes in 1.1.8 (2006.06.30):
[cd39f67]1334
[c988ae4]1335* Drop support for building with wxWidgets versions prior to 2.4.0
1336  (which was released on 2003-01-07).
1337
[9577fcc]1338* aven: Printing through aven now uses settings from the "[aven]" section
1339  of print.ini, and support for hierarchical sections (using "like=")
1340  has been disabled.
1341
[ecf2d23]1342* aven: Change mouse actions to be compatible with those in Survex 1.0.
1343  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1344  left drag is now smart about not rotating and zooming at the same
1345  time.
1346
[d1628e8e]1347* aven: Highlighting stations now happens as you type, and pressing
1348  "Enter" or clicking the "Find" button now pans and zooms to show the
1349  highlighted stations.
1350
[e67ed1b]1351* aven: Left-clicking away from a station now cancels measuring line.
1352
[3ddd351]1353* aven: Setting view to North, South, East, or West is now animated like
1354  the tilt from plan to elevation.
1355
[c988ae4]1356* aven: Fix presentation saving to also write "." for decimal points and
1357  presentation loading to accept either "." or ",".
1358
1359* (Unix version): aven: Add text for all toolbar items so that aven
1360  will work with the Gnome desktop preference for displaying toolbars as
1361  icons with text or just text (wxWidgets needs fixing first though).
1362
1363* (Unix version): aven: Remove the ability to detach the menu bar (yell
1364  if you actually used it and I'll restore it!)
1365
1366* aven: Add "all survey files" option to the "open file" dialog.
1367
[84f1ed1]1368* (MS Windows version): aven: Fix cursor keys to pan survey.
1369
[a884696]1370* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1371
[9fe7af4f]1372* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1373  run by an unprivileged user.
1374
1375* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1376  installer builder we use) and include new installer translations for
1377  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1378
1379* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1380  translations of messages for wxWidgets (the GUI library we use).
1381
[cd39f67]1382* aven: Disable "Highlight exported points" if there aren't any.
1383
[afffec4]1384* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1385  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1386
[38a192d]1387* (Unix version): test suite: fix smoke test to pass even without X running
1388  (it was meant to but the code had a bug).
1389
[5892e08]1390* aven: Check if OpenGL is available and exit cleanly with a helpful error
1391  if it isn't.
1392
[879e9c3]1393* (Unix version): aven: Fix --help and --version to work without a working
1394  X display (provided it's built with wxWidgets 2.5.1 or newer).
1395
[c8f929b]1396* aven: Automatically select the presentation tab of the notebook when the user
1397  selects "New Presentation" or "Open Presentation".
1398
1399* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1400  reset to default view as well).
1401
1402* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1403  empty.
1404
1405* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1406  up and down instead of being passed on and moving the survey.
1407
[9ad92cc]1408* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1409  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1410  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1411
1412* aven: Put a 5mm border around exported SVG files to allow for station markers
1413  and non-zero width lines.
1414
1415* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1416  was turned on.
1417
1418* aven: Actually close the file we're exporting which fixes problems with it
1419  not always being fully written.
1420
[920b066]1421Changes in 1.1.7 (2005.10.18):
[6662d02]1422
1423* cavern: Add validity checking for dates in *date commands (with feature
1424  test in testsuite).  A date entered as just "year" or "year.month" now
1425  becomes a date range for the relevant period (previously it became a single
1426  date near the middle of that period).
[e0c7cd1]1427
[8add4c9]1428* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1429  with MS Windows).
1430
[9f524ee]1431* extend: Default output name for a file called input.3d is now input_extend.3d
1432  rather than just extend.3d (which was annoying if you wanted to extend
1433  several surveys in the same directory).
1434
[185d793]1435* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1436  our check for them to include that knowledge.
[185d793]1437
[3515947]1438* aven: Regenerate depth bar if user switches to/from metric units.
1439
[1235f9b]1440* aven: Don't clear the "there" mark just because the mouse pointer has
1441  moved off a station.
1442
[4299674]1443* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1444  same directory (since that's where we then try to load it from).
[4299674]1445
[60dbe70]1446* aven: Fix labelling of date colouring on 32 bit platforms.
1447
[125c9ea]1448* aven: If "colour by date" is on and we load a survey with no date info
1449  (or all surveyed on the same date) then set "colour by none".
1450
[ec58e3d3]1451* aven: Make the error dialog modal and remove a signal handler once it
1452  has fired to prevent endless (or seemingly endless) cascades of error
1453  dialogs.
1454
[8add4c9]1455* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1456  if a survey file with only one station in is loaded.
1457
[6662d02]1458* aven: Fix problems with indicators disappearing when we're drawing
1459  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]1460  introduced in 1.1.6).
[6662d02]1461
[b65c13f]1462* (Unix version): aven: Really stop setting extra toolbar margin when using
1463  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1464  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1465
[17cce5f]1466* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1467  we've been compiled with, and which GTK+/Motif version where appropriate.
1468
[affaeee]1469* (Unix version): Fixed build on Fedora Core 3.
1470
[618b01f]1471* documentation: Updates to 3d file format specification from Mike McCombe.
1472
[920b066]1473Changes in 1.1.6 (2005.10.10):
[7e01c87]1474
1475* (MS Windows version): Distribution is about a third smaller than 1.1.5
1476  (mostly because mingwm10.dll is no longer required).
1477
[b88b171]1478* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1479  it, showing cavern's output in a window (with errors and warnings clickable
1480  to load the offending file into an editor), and then loading the resulting
1481  3d file.
1482
[7e01c87]1483* aven: Added "Colour by Date" option.
1484
1485* aven: Disable "Colour by Depth" option if there's no elevation variation.
1486
1487* aven: Don't crash if trying to load a survey with no elevation variation.
1488  Instead turn off depth colouring.
1489
[8ea82aa]1490* aven: Export as HPGL added.
1491
[887c26e]1492* aven: Improved update of mouse coordinates and measuring line (thanks to
1493  Martin Green).
1494
[7c29c976]1495* aven: Show the coordinates of either the mouse pointer or the nearest
1496  survey station to it (if there is one near enough).  Showing both was
1497  confusing and meant the status bar overflowed on smaller displays.
1498
[7e01c87]1499* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]1500
[7e01c87]1501* aven: Don't lock "flat" surveys which aren't extended elevations - a
1502  flat survey with LRUD data isn't flat any more!
1503
1504* aven: When we have to draw blobs and crosses the slow way (because the
1505  graphics hardware doesn't support the fast way), draw them so that they
1506  should appear at the correct depth into the 3D scene instead of on top
1507  of everything else.
1508
1509* aven: Make "play presentation backwards" icon green to match the other
1510  presentation icons.
1511
1512* (MS Windows version): aven: Mouse clicks on the survey view now set the
1513  keyboard focus there.
[bd21214]1514
[b46bf92]1515* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1516
[796d7bf]1517* (MS Windows version): aven: Fix redrawing of measuring line.
1518
[7e01c87]1519* cavern: Store dates for img_XSECT.
1520
1521* cavern: Fixed small one-off memory leak if you specify -o more than once.
1522
[b88b171]1523* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1524  language to use for messages.
1525
[7c29c976]1526* (MS Windows version): "Print" on a 3d file now prints through aven rather
1527  than the separate printer driver (Unix has done this for some time).
1528
[8ea82aa]1529* Removed old printer drivers.
1530
[7e01c87]1531* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1532  to write a file format version which doesn't support it.
[8ea82aa]1533
[920b066]1534Changes in 1.1.5 (2005.09.20):
[106cfdf]1535
1536* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1537
[4ba80e0]1538* aven: Make blobs round like they are in Survex 1.0.
1539
1540* aven: If the graphics drivers don't support drawing blobs using OpenGL
1541  point markers, fall back to drawing filled circles.
1542
[95ce35f]1543* aven: If the graphics drivers support it, draw crosses as texture mapped
1544  OpenGL point markers which is much faster.
[90d0d71]1545
[95ce35f]1546* aven: Cross size increased to match Survex 1.0.
1547
[cd78148]1548* aven: We must update which blobs are displayed if display of surface or
1549  underground legs is toggled.
1550
[f5627353]1551* cavern: Fix handling of a *solve followed by survey data, none of which is
1552  attached to the previous data.
1553
[dfe4a520]1554* cavern: Fixed "No survey data" error when a *solve is followed by another
1555  *solve (or the implicit solve at the end of processing) with no data between
1556  them.
1557
[920b066]1558Changes in 1.1.4 (2005.09.19):
[4855072]1559
1560* aven: Added Aven's icon to the "About" dialog.
1561
1562* aven: Use localised character for the decimal point (e.g. "," in most
1563  continental European countries).
1564
1565* aven: Previously the survey tree would get focus and then take keypresses
1566  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1567  operate on the cave, and transfer the input focus across when we do.
1568
1569* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1570
1571* aven: Speed up intialisation by delaying creation of OpenGL lists until
1572  they're needed.
1573
1574* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1575
1576* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1577
1578* aven: Reworded "Restore Default Settings" as "Restore Default View".
1579
1580* (Unix version): aven: Set sensible default margins for printing and preserve
1581  any margin values the user specifies between runs (previously margins
1582  defaulted to 0 each time aven was run).
1583
1584* Documentation: Document *DATA PASSAGE in the manual.
1585
[920b066]1586Changes in 1.1.3 (2005.09.07):
[0e558e5]1587
1588* (Microsoft Windows version): Fixed build problems.
1589
1590* cavern: Allow OMIT character (-) for left/right/up/down.
1591
1592* aven: Remove an unnecessary menu separator.
1593
1594* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1595
1596* aven: Make the tooltip for "Hide" show the number of found stations.
1597
1598* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1599
1600* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1601  when there's a presentation loaded.
1602
1603* aven: Make entrances green in side panel tree list to match green blobs used
1604  in cave view.
1605
1606* aven: Don't show surface labels if we're not showing surface data, etc.
1607
1608* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1609  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1610  existing users are happy, but don't advertise it.
1611
1612* aven: Normalise filename by adding any extension used, and use the normalised
1613  filename for file history and window title.
1614
1615* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1616  as the toolbar buttons already have a sensible margin - the extra margin is
1617  only needed with GTK1.2.
1618
1619* aven: Fix handling of plumb legs in tube model.
1620
1621* aven: Fixed swapped L and R in tube model.
1622
1623* extend: Preserve UD cross-section information in extended elevation.
1624
1625* extend: Add new messages for John Pybus' enhancements.
1626
1627Changes in 1.1.2 (never formally released):
[8faa5d8]1628
1629* Added support for LRUD data in .svx files, in .3d files, and aven can
1630  now load and display it on screen and on printouts.  The ability to "fake"
1631  LRUD data in aven is gone for now but will reappear in some form later.
1632
1633* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1634  fold any desirable missing chasm functionality into aven.
1635
1636* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1637  cursors for each different mouse action to help the user learn what each
1638  does.  Also added cursors for the "compass" and "clino" as well as the
1639  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]1640
[0e558e5]1641* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]1642
1643* tests/smoketest.tst: If X windows is running, check that we can run aven
1644  with --help and --version.
1645
1646* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1647  no results are listed for it.  This revealed that there was a "newline" test
[6225339]1648  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]1649  Fixed all these problems.
1650
1651* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1652  and omitted forward compass/clino readings in Compass DAT files.  Added
1653  a feature test for this to the testsuite.
1654
1655* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]1656  without OpenGL so remove old machinery for this from configure and the
1657  sources.
[8faa5d8]1658
[0e558e5]1659* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]1660
1661* configure: Better output for strcasecmp test.
1662
1663* aven: Fix crosses to work much better.  Not a total fix - their position
1664  in the Z buffer isn't correct and they're rather slow to plot.
1665
1666* aven: Don't regenerate the hittest grid every time the mouse moves while
1667  animating, which solves the mysterious pausing effect (thanks go to Martin
1668  Green for spotting this!)  Also clear all the status bar coordinates when
1669  animating.
1670
1671* aven: Sort out clashing menu shortcuts in some languages.
1672
1673* aven: Fixed compilation problem on x86_64
1674
1675* SPUD: Pruned out stuff which has been done or which is not actually relevant
1676  to this branch.
1677
1678* Merge various changes from 1.0 branch:
1679
1680  + aven: Port over "printing from aven" functionality.
1681
1682  + aven: Port over "export as" functionality,
1683
1684  + Add David Loeffler's vim mode for .svx files.
1685
1686* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]1687
[8faa5d8]1688* aven: Don't use an opengl list for drawing the indicators - we typically make
1689  a new list each time we plot them anyway.
1690
1691* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1692
1693* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]1694  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]1695
1696* configure: Update wxWindows checks to handle newer wx versions.
1697
1698* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
1699  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
1700  for anyone building from CVS).
1701
1702* acinclude.m4: Quote macro name for fix autotools warning.
1703
[4855072]1704* Documentation: "tilt up" is "'" not ",".
[8faa5d8]1705
1706* aven: Add support for mousewheels (to tilt the cave).
1707
1708* aven: Fixed twisted transitions to and from pitches in certain cases.
1709
[0e558e5]1710* aven: Pick a sensible initial window size when the user's desktop is spread
1711  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]1712  better with wx2.4 or earlier as well).
1713
1714* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
1715  contents being visible before any survey is loaded.
1716
1717* aven: Allow a coloured texture to be used
1718
1719* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]1720  is default colour (grey for most systems) not black until a survey is
1721  loaded).
[8faa5d8]1722
1723* aven: Fixed weird "shadowed" icons.
1724
[920b066]1725Changes in 1.1.1 (2004-10-06):
[a7aa27d9]1726
1727* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]1728  startup.
[a7aa27d9]1729
1730* aven: Delay loading the bitmap for the "About" dialog until it is first
1731  needed.  We want start up to be as quick as possible.
1732
[920b066]1733Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]1734
[91e416e]1735* NOTE: Survex 1.1.X releases are development snapshots made available for
1736  the purposes of allowing wider testing and getting more user feedback.  Once
1737  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]1738
[91e416e]1739* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
1740  you're using Windows 95 - these can be obtained from:
1741  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]1742
[91e416e]1743* aven: Solid passages - passage dimensions are currently inferred from
1744  the leg length (pretty effective as you can measure longer legs in
1745  larger passages).  Use of real LRUD data coming soon...
[edb6576]1746
[91e416e]1747* aven: Depth colouring is now continuously varying.
[edb6576]1748
[0580c6a]1749* aven: Colour by depth can now be turned off (and there's the start of a
1750  framework for properly implementing colour by date, error, etc).
1751
[4261983]1752* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
1753  match (? matches any character, * matches any number of characters).
1754
1755* aven: We now use the status bar for coordinates, distances, etc to make
1756  better use of screen space.
[edb6576]1757
[f80077a]1758* aven: Full screen mode (F11).
[edb6576]1759
[6abab84]1760* aven: Perspective view.
1761
[91e416e]1762* aven: Context sensitive cursor shape - needs more work.
[edb6576]1763
[91e416e]1764* aven: Mouse actions changed (hopefully they're now more natural, but
1765  you may find the change disorientating - feedback wanted on this).
[edb6576]1766
[1690fa9]1767* aven: Added "presentations" which allow you to set up fly-through paths
1768  and load/save/run them.
1769
[0580c6a]1770* aven: A presentation can be exported as a movie file.
1771
[045e2af]1772* aven: Added Save screenshot facility.
1773
[c60062d]1774* aven: Depth fogging option.
1775
[0580c6a]1776* aven: Added Smooth Lines option.
1777
1778* aven: Added Textured Walls option.
1779
[f433fda]1780* aven: If a survey has surface legs but no underground legs, default to
1781  showing the surface legs.
1782
[0580c6a]1783* cavern: Dates given to *date are now stored in the 3d file.
Note: See TracBrowser for help on using the repository browser.
