[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
[515b83e]8* aven: Fix the conditions on which the menu item "Cancel measuring line" is
9  enabled - previously it was hard to actually cancel it via the menu.
10  Reported by Hugh St Lawrence.
11
[5c676e2]12* aven: Fix wx assertion failures when showing hit test debug view on platforms
13  such as 64-bit Linux.
14
[2c5ec88]15* aven: When viewing from above, show "Plan" above the "clino" which indicates
16  the tilt angle (instead of "Elevation -90°").
17
[5c676e2]18* aven: The extended font data now loads faster, and also uses less memory on
19  64-bit platforms.
20
[2c5ec88]21* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
22  the space available in the aven UI.
23
[515b83e]24* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
25  and handle it in the same way as the "DUPLICATE" flag in .svx files.
26
[2c5ec88]27* (Microsoft Windows version): Include dump3d in the installer.
28
[5c676e2]29* Fix a compiler warning.
30
31* Improve test coverage.
32
[0d365be]33Changes in 1.2.13 (2014-05-15):
[acbb5b1]34
[8ccd1d8]35* aven: Fix --print option to wait for printing to happen before exiting
36  (previously it would exit right after opening the print dialog, so you
37  couldn't actually print anything out using it).
38
[acbb5b1]39* aven: Increase the threshold for how close the pointer needs to be to a
40  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
41  Hugh St Lawrence.
42
[0d365be]43* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]44  if increasing the minimum pointer to station threshold helps Hugh's problems
45  with using aven on a touch screen device.
46
[acbb5b1]47* aven: The measuring line was unable to see stations which had just been
48  revealed by toggling surface or underground legs on - this is now fixed.
49
50* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
51  many entries are in each box (toggled by F3).
52
53* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
54  off and back on.
55
56* aven: Create the empty hit-test grid data structure lazily, to reduce start
57  up time a little.
58
59* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
60  and *end commands to instead talk about "survey names".
61
62* cavern: For ages cavern has warned if you reentered a survey, but this
63  warning was suppressed if it occurred at the same line of the same file as
64  the survey was first entered, but this can only happen if you include the
65  same survey file more than once, which isn't a sensible thing to do for a
66  file with actual survey data in (you might reasonably do it to set up survey
67  grade details or something like that).  The warning is now given in this
68  situation too.
69
70* cavern: After 5 warnings about reentering a survey we give up warning about
71  it, but we used to keep reporting where the survey was originally entered -
72  this secondary diagnostic message is now silenced when the main message is.
73
74* (Microsoft Windows version): Compile C code with optimisation on.
75
76* Add the start of a Russian translation, with messages take from therion.
77
78* Minor translation updates to French.
79
80* Fix compiler warning from GCC.
81
82* Testsuite improvements:
83
84  + Test that "..." anon station works.
85
86  + cavern.tst: Check number of errors returned by all testcases which should
87    fail and give an error count.
88
89  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
90
[ad727d8]91Changes in 1.2.12 (2014-04-14):
[46d12e9]92
[63e8642]93* aven: Fix measuring line to show change in altitude rather than altitude
94  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
95  Clipstone.
[46d12e9]96
[ad727d8]97* aven: Fix printing when built with wxWidgets 3.0.
98
99* aven: Several visual improvements to printouts:
100
101  + Move the numbers below the scale bar down a little so that they don't
102    overlap the scale bar ticks.
103
104  + Set the clipping region after we draw the page border and info box to avoid
105    clipping the border in print preview.
106
107  + Tidy up the appearance of the compass and elevation arrow.
108
[63e8642]109* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
110  <http://bugs.debian.org/739332>.
[46d12e9]111
[63e8642]112* aven: Fix to build with older libav where avcodec_free_frame() isn't
113  available.
[46d12e9]114
[ad727d8]115* (Linux version) survex.spec: Update spec file used for building RPM packages.
116
117* (Unix version): Add "Keywords:" entry to .desktop files.
118
119* (Unix version): Enable large file support, mostly to support filing systems
120  which return 64 bit inode values, such as CIFS mounts.
121
[63e8642]122* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
123  rather than any character which is a letter in the current locale.
[46d12e9]124
[63e8642]125* Various translation updates.
[46d12e9]126
[aac3336]127Changes in 1.2.11 (2014-01-28):
[fb941bfd]128
129* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
130  Reported by Kevin Dixon.
131
[aac3336]132* aven: Embed the font data for the first 256 Unicode characters for use in the
133  survey pane into the compiled aven binary to reduce start up overhead.  Any
134  additional characters needed are loaded from a data file only if/when a
135  character >= U+100 is actually needed (as before).
136
[ad3017d]137* aven: Fix display of Unicode characters above 256 when there's a character
138  <= 256 earlier in the same string.
139
[77bdacf]140* aven: Use the actual width of Unicode characters above 256 rather than
141  assuming they are 16 pixels wide.
[ad3017d]142
143* aven: If full screen, don't show the side panel when a new file is opened
144  (e.g. via Ctrl+O).
145
146* aven: Don't give an assertion failure when showing passages for a cave with
147  no vertical extent.  Reported by Jonny Prouty.
148
149* aven: Change terminology in print dialog - say "legend" instead of "info
150  box".
151
152* aven: Add option to show the tilt angle as a percentage gradient.
153
154* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
155  indicators.
156
157* aven: All length units are now translatable.
158
[fb941bfd]159* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
160  will reduce code size and also the number of deprecation warnings about
161  gluErrorString on Mac OS X 10.9.
162
[ad3017d]163* (Microsoft Windows version): aven: Try to work around redraw issues related
164  to the measuring line by redrawing the whole window, which doesn't seem to be
165  measurably slower.
166
167* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
168  give an error rather than quietly ignoring the attempt.
169
[77bdacf]170* cad3d: Make cad3d remap control characters and spaces in station names when
171  generating PLT output in the same way aven does.
172
[ad3017d]173* Various translation updates (particular thanks to Eric Madelaine and Dennis
174  Baudys), including the start of a Bulgarian translation, with messages taken
175  from Therion and elsewhere.
176
177* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
178  GetUserDefaultUILanguage() to get the UI language to use.  For older
179  versions, continue to use GetUserDefaultLCID().
[fb941bfd]180
181* (Microsoft Windows version): The Indonesian translation will now be used
182  automatically when the system language is set to Indonesian.
183
184* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
185  A. Riggs for his work on this.
186
187* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
188  checksum check for the downloaded wx sources.
189
190* Fix a lot of the compiler warnings when building with clang.
191
[ad3017d]192* doc/manual.sgml: Add missing quantities to the list documented as accepted by
193  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
194  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
195  mentioned in list of the units that can be set for them); COUNT (missing
196  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
197  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
198
199* Test suite: Improve test coverage for cavern.
200
[0ecf3b1]201Changes in 1.2.10 (2014-01-15):
202
203* aven: Fix assertion if two mouse buttons are held down at the same time.
204  If dragging with more than one mouse button held down, releasing one causes
205  another which is still held down to take effect.  Reported by Brian
206  Clipstone.
207
[53966d3]208* aven: If we fail to start the external editor when the user clicks on an
209  error or warning from cavern, show an error box.
210
[6f0d0d8]211* aven: If the survey has a title, add it as a top-level <title> element to
212  exported SVG files.
213
214* aven: Escape '<', '>', and '&' in labels in exported SVG files.
215
216* aven: In GPX export, set the <time> element to the datestamp from the 3d
217  file.
218
219* aven: Don't try to write the title if it isn't set or is empty when exporting
220  GPX files.
221
222* aven: Don't bother looking up the printer page setup info when exporting.
223
[0ecf3b1]224* (Microsoft Windows version): aven: Fix crash on "File->Print" or
225  "File->Export" under Windows XP, reported by Brian Clipstone.
226
227* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
228  encoded filename which could occur if run without being asked to load a file
229  on startup.
230
231* (Microsoft Windows version): aven: Compile with optimisation on.
232
233* img library, aven: Although processed CMAP data files are often referred to
234  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
235  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
236  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
237  continue to do so in case anyone is relying on it, but also check for the
238  other extensions.
239
240* img library: Add new "datestamp_numeric" field to struct img giving the
241  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
242  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
243  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
244  timezone wrong.
245
246* img library: Fix my_strcasecmp() to handle top-bit set characters better.
247
[6f0d0d8]248* cavern: Fix NULL pointer dereference when processing Compass DAT file without
249  'SURVEY DATE:'.
[0ecf3b1]250
[6f0d0d8]251* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]252
[6f0d0d8]253* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]254
[53966d3]255* Fix some compiler warnings if built with glibc's fortify source feature
256  enabled.
257
[6b6fb4d]258Changes in 1.2.9 (2014-01-08):
259
260* Document --3d-version in cavern man page and the manual.
261
262* aven: Fix compilation error in movie export code with recent libavi.
263
264* aven: Fix warning on stderr when export a movie as MPEG.
265
266* img library: In non-hosted mode, don't define GETC and PUTC if they're
267  already defined, to allow easy overriding with getc_unlocked() and
268  putc_unlocked() (which are significantly faster on Linux).
269
270* img library: In non-hosted mode, check that int is at least 32 bits,
271  and if not, use long.  In practice, platforms with 16 bit int are mostly
272  obsolete, but it's not hard to be portable here.
273
274* img library: Add test that img.c and img.h compile in non-hosted mode
275  (regression test for issue fixed in 1.2.8).
276
277* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
278
279* Update translations from launchpad and from existing similar messages.
280
281* Fix some compiler warnings.
282
[e1f27c4]283Changes in 1.2.8 (2013-10-29):
[da65891]284
285* cavern: Fix handling of anonymous wall stations ('..' by default) to
286  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
287  Holder.
288
[e1f27c4]289* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]290  statistics when the value gets large.
291
[a4adf09]292* cavern: Eliminate redundant progress message when solving simultaneous
293  equations.
294
[e1f27c4]295* aven: Add a format drop down to the export dialog, and only show fields which
296  are meaningful and supported for the currently selected export format.  The
297  format defaults to that used most recently.  The "Elements" and "View" boxes
298  have been swapped in the print and export dialogs as that layout works much
299  better when the "View" box is hidden.
300
[0056ee1]301* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
302  - now works again.  Reported by Anthony Day.
303
[e1f27c4]304* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
305  this release the projection which the survey coordinates are in defaults
306  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
307  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
308  projection string.  The ability to specify this projection in a better
309  way is coming soon.
310
311* aven: New export options "Origin in centre" and "Full coordinates" - the
312  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
313
314* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
315  time ago, so update references.
316
317* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
318  with wxMSW 2.9.5.  Reported by Brian Clipstone.
319
320* aven: Make right click in an empty presentation mark the current position and
321  open it to edit, instead of crashing.
322
323* aven: Update movie export code to work with latest libav API.  Reported by
324  Sebastian Ramacher.
325
326* aven: Improve reporting of errors during the process of exporting a movie.
327
328* aven: Don't try to close the movie if we aren't producing one.
329
330* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
331
332* aven: Fix to build with wxMSW 2.9.5.
333
334* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
335
336* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
337  ago, so add a new --skencil option to specify this output format.  The old
338  name (--sketch) is still recognised for compatibility.
339
340* cad3d: Make --marker-size work for Skencil and SVG output.
341
342* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]343
[88b54df6]344* img library:
345
[e1f27c4]346  + Fix to work once more when used outside of Survex (missing definition of
347    max() macro and a bad call to free() in img_close() for a file opened for
348    reading).
349
350  + Use lround() instead of round(), and make the tests around whether we use
351    the library function or the our fallback implementation saner.
352
353  + Fix // comments in C code for portability to pre-C99 compilers which don't
354    support these as an extension.
[88b54df6]355
[f807d8bf]356  + Can now be compiled as C++ as well as as C.
357
[e1f27c4]358* (Microsoft Windows version): The installer is now built with a newer version
359  of Innosetup, and includes translations for all the languages which Survex
360  itself has any translations for.
361
362* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
363
364* Minor translation updates.
365
366* tests/Makefile.am: Distribute files for "normal_bad" testcase.
367
[e34bebc]368Changes in 1.2.7 (2013-07-27):
[65d9b6b]369
[e34bebc]370* Add support for anonymous stations, which are indicated by one, two or three
371  separator characters - with the default separator of '.', that means '.',
372  '..', and '...' are anonymous stations.  Single separator ('.' by default)
373  is an anonymous non-wall point, double separator ('..' by default)
374  is an anoymous wall point at the end of an implicit splay), and triple
375  separator ('...' by default) is an anoymous point (with nothing special about
376  the leg).  A new *alias command allows '-' to be mapped to '..' for
377  compatibility with pocket topo: *alias station - ..
[07beaa4]378
[e34bebc]379* New version 8 of the 3d format:
[07beaa4]380
[e34bebc]381  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]382
[e34bebc]383  + New explicit file-wide flag for 'this is an extended elevation', rather
384    than modifying the survey title to indicate this.
[da9d788]385
[e34bebc]386  + The survey prefix is often unchanged from one leg to the next, so use a
387    spare flag to compactly indicate when there's no label change.
[da9d788]388
[e34bebc]389  + The data style of each leg is now stored.
[da9d788]390
[e34bebc]391  + The "processed at" time is stored as seconds since 1970 rather than a
392    human-readable string.
[da9d788]393
[e34bebc]394  + Since 3d v8 features significant changes to the format, the format
395    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]396
[e34bebc]397* img library:
[da9d788]398
[e34bebc]399  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]400
[e34bebc]401  + Handle .pos files containing unnamed stations - don't suck the next line in
402    as the station name, and set img_SFLAG_ANON for them.
[da9d788]403
[e34bebc]404  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
405    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
406    elevation, in place of appending " (extended)" to the title.  Internally we
407    still append this to the title (and remove it upon reading) when writing
408    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
409    explicitly in the file.
[da9d788]410
[e34bebc]411  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]412
[e34bebc]413* aven:
[da9d788]414
[e34bebc]415  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
416    now, and the wx developers consider even 2.8 to be rather long in the
417    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
418    formally dropping support for older versions allows a number of workarounds
419    to be removed from the aven source code.  Also, features deprecated in
420    wxWidgets 2.9 are no longer used in our code.
[da9d788]421
[e34bebc]422  + Don't run incremental search on every key-press, as on a slow machine the
423    short initial search(es) will take a while but not be useful.  Instead only
424    actually run the search when we're told there are no more key-presses
425    queued up.
[da9d788]426
[e34bebc]427  + Implement support for including cross-section information in exported SVG
428    and DXF files (ticket#4).  The DXF export is untested currently.
429
430  + Show splay legs faded by default, with menu options to hide them or show
431    them like other legs.
432
433  + Speed up loading a .3d file with cross-sections by using a map to convert
434    station names to positions.
435
436  + In the cavern log window, don't highlight a file:linenumber if there's no
437    message after it, which avoids highlighting the "Included from" lines
438    wrongly.
439
440  + Fix not to crash when trying to report an error while starting up.
441
442  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
443    the OS X standard shortcut Shift-Command-F (previously we used F11, but
444    that's used by the desktop).
445
446  + Add checks for errors when reading the font file.
[07beaa4]447
[e34bebc]448  + Remove useless extra quoting when invoking vim to show the location of an
449    error from cavern.
[07beaa4]450
[e34bebc]451  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]452
[e34bebc]453  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
454    in the dialog in sync.
[da9d788]455
[e34bebc]456* cavern:
[3dfffa2]457
[e34bebc]458  + Demote errors about invalid dates to warnings, since we've accepted *date
459    for ages without any checks on the value, and so existing datasets
460    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]461
[e34bebc]462  + New *alias command allows '-' to be mapped to '..' for compatibility with
463    pocket topo: *alias station - ..
[07beaa4]464
[e34bebc]465  + We want to warn if there's a clino reading which it would be impossible to
466    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
467    read "93" (it's probably a typo e.g. for "39").  However, the gradient
468    reading from a topofil is typically in the range 0 to 180, with 90 being
469    horizontal.  Really we should allow the valid range to be explicitly
470    specified, but for now we infer it from the zero error - if this is within
471    45 degrees of 90 then we assume the instrument can read between 0 and 180
472    degrees.
[da9d788]473
[e34bebc]474  + If the survey isn't all connected, still run survey tree checks and report
475    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
476    Dixon for the report which highlighted this issue.
[da9d788]477
[e34bebc]478  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]479
[e34bebc]480  + Report column numbers as well as line numbers for some cavern errors and
481    warnings.
[07beaa4]482
[e34bebc]483  + Adjust width of node stats table to fit longest count when there are more
484    than 9999 of a particular order of node.
[07beaa4]485
[e34bebc]486  + If the argument to *include has an opening double quote but the closing
487    double quote is missing, then skip trying to open the file.
[da9d788]488
[e34bebc]489  + Move "Station X referred to just once" warning after non-existent survey
490    check - if both fire, the non-existent survey error is likely to be more
491    relevant.
[da9d788]492
[e34bebc]493  + We no longer follow an error for a bad reading in passage data with a bogus
494    "End of line not blank" error, but instead check the remaining readings on
495    the same line.
[da9d788]496
[e34bebc]497  + We no longer follow an error about OMIT for a required reading with a bogus
498    "End of line not blank" error.
[7f6250a]499
[e34bebc]500  + Report an error if the scale factor in *calibrate is zero - it doesn't make
501    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]502
[e34bebc]503  + Report the parent include files starting from the outermost, as that's more
504    logical when there are multiple levels involved.
[07beaa4]505
[e34bebc]506  + If we were expecting a numeric field and instead get something which starts
507    with '+', '-', or '.' but which isn't a number, then fix the error to
508    include that character in the token reported.
[3dfffa2]509
[e34bebc]510  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
511    first item.
[07beaa4]512
[e34bebc]513* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]514
[e34bebc]515* dump3d:
[07beaa4]516
[e34bebc]517  + Build, install and package dump3d as standard - it's useful for grabbing
518    info from 3d files in scripts.
[07beaa4]519
[e34bebc]520  + Add --show-dates option.
[07beaa4]521
[e34bebc]522  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]523
[e34bebc]524  + Report the data style of legs.
[da9d788]525
[e34bebc]526  + Report if the file is an extended elevation.
527
528  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]529
530* Test suite:
531
532  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
533    expected output so it passes reliably.
534
[e34bebc]535  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
536    'Deleted' stations upon failure are the more natural way round.
537
[07beaa4]538  + Add more testcases, expand some existing testcases, and add expected output
539    for more.
540
[e34bebc]541* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
542  appropriate C and C++ compilers to use, and link mingw build statically to
543  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]544
545* (Unix version): When determining the character set for command-line tools,
546  check environmental variable LANG after LC_ALL and LC_CTYPE.
547
548* When determining the language, check environmental variable LC_ALL before
549  LC_MESSAGES and LANG (but after SURVEXLANG).
550
[e34bebc]551* If we don't find the message file, only give an error if it was specified
[665183c]552  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]553  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
554  settings.
555
556* There are a handful of hard-coded English message strings for reporting
557  errors trying loading message files, etc.  These are all now ASCII, as if we
558  fail trying to open a message file, it's more likely the encoding isn't
559  set correctly.
560
561* Prune strings we are no longer using and are probably unlikely to use again
562  into a new file po_codes_dead, so that translators don't get presented with
563  them to translate.
564
[07beaa4]565* Merge lots of translation updates.  Most translations are now complete or
566  close to complete.
[3dfffa2]567
568* Add start of Indonesian translation from Arief Setiadi Wibowo.
569
[07beaa4]570* Fix various compiler warnings when building from source.
571
[e34bebc]572* Include scripts gdtconvert and gen_img2aven in the source distribution.
573
[c575465]574Changes in 1.2.6 (2012-02-23):
[b081031]575
576* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
577
578* (Microsoft Windows version): Include JPEG images for aven in the installer
579  package (ticket#35).
580
581* cavern: If we have a reference to a station in a non-existent survey, give a
582  helpful error rather than saying the station hasn't been exported from the
583  survey.  (Bug reported by Martin Green via email)
584
585* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
586  Kahler.
587
588* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]589  .gpx file with waypoints for entrances.  This needs libproj so is disabled
590  by default for this release - to enable it install the development stuff for
591  libproj and build survex with:
592
593      make FINDENTRANCES=findentrances
594      make install FINDENTRANCES=findentrances
[b081031]595
596* dump3d: Add support for showing img_ERROR_INFO items.
597
598* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
599
600* Incorporate a French translation from launchpad I'd previously copied the
601  English version of by mistake.  Attempt to correct mistranslation of "survey
602  file".
603
[685116f]604Changes in 1.2.5 (2012-01-03):
605
606* aven:
607
608  + The survey tree in the left panel is now in sorted order once more.
609
610  + No longer fails with an assertion if used for a long time (we were leaking
611    an OpenGL list each time one had to be regenerated).
612
613  + Now builds with newer FFmpeg library.
614
615  + Draw measuring line in front of the indicators rather than behind them.
616
617  + Loading a new file (or reloading the current one) no longer invalidates
618    the OpenGL lists for the compass and clino, so will be a fraction faster.
619
620* Improve handling of attempts to look up translated messages before the
621  message subsystem is fully initialised (which only happens if there's an
622  error early on).
623
624* Improve the survex(7) man page text, and fix it to be marked as section 7 in
625  the man page source as well as in the filename.
626
[f15ca67f]627Changes in 1.2.4 (2012-01-01):
628
629* aven:
630
631  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
632    initialised, which doesn't cause problems in some machines, but causes aven
633    to abort on others.  This is now fixed, and there's a check in place to
634    help avoid similar issues in future. (ticket#34)
635
636  + Always use metres or feet for the depth colour key, and chose a consistent
637    precision by looking at the depth range. (ticket#30)
638
639  + Show the depth units below the colour bar rather than after every value.
640
641  + When zooming way in, stay in metres rather than switching to cm.
642
643  + On the scale bar, say “1 mile” rather than “1 miles”.
644
645* Translation updates for Catalan, French and Slovak.
646
[5b9942e]647Changes in 1.2.3 (2011-12-31):
648
649* Fix to build with wxWidgets 2.9.2.
650
651* (Mac OS X version):
652
653  + Processing .svx files from aven now works.
654
655  + Remove spurious blank lines from the licence text in "Get Info".
656
657  + Don't create the help menu at all, as it is empty (because the "About"
658    entry goes elsewhere) and sometimes seems to appear in the UI.
659
660  + INSTALL.OSX: Update to reflect current status.
661
662* aven:
663
664  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
665
666  + Improvements to text plotted on the survey pane:
667
668    - Support plotting Unicode character points > 256 by lazily loading the
669      data for them from the font file and plotting them with a direct call to
670      glBitmap(), which is slower but doesn't require a display list per
671      character.
672
673    - Adjust the spacing from fixed width to putting a one pixel gap either
674      side of each one character (so two between adjacent glyphs).  Mostly this
675      reduces the horizontal width, but it adds a pixel for characters like "m"
676      and two in a few cases.
677
678    - Fix .pixelfont file generation to correctly handle characters wider than
679      8 pixels.
680
681  + Fix expected cross shape so don't always reject using texture mapping to
682    draw crosses.
683
[3ea0178]684  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
685    as those consisting of just one.  Previously we would trip over the empty
686    tube later.  Such tubes can for example be created by extend if a splay shot
687    is the start or end of a tube.
688
[5b9942e]689  + Make the green colour used for entrances in the survey tree the same
690    (slightly darker than before) green used for the entrance blobs.
691
692  + Report the version of the library we're actually running with if built
693    against wx >= 2.9.2.  Make it clear that the version reported is the
694    version *built* with for wx < 2.9.2.
695
[3ea0178]696* extend:
697
698  + Copy the end markers for passage tubes.
[5b9942e]699
[3ea0178]700  + Preserve left and right data for tubes (previously they were set to -1.0
701    which means "no info").
702
703* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
704  was no longer used - it certainly is!
705
706* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
707  messages, and curly single right quote instead of straight ASCII apostrophe.
708  Fall back to using straight ASCII versions if we can't represent them in the
709  current character set.
[5b9942e]710
[3ea0178]711* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]712
713* Test suite:
714
715  + Add test coverage for interleaved diving data.
716
717  + Add testcase for diving data with topofil-style distance.
718
[94960ad]719Changes in 1.2.2 (2011-10-06):
720
721* aven:
722
723  + Replace the textured-mapped font drawing with an approach based on
724    glBitmap.  This doesn't suffer from the character alignment issues which
725    the textured-mapped fonts had, and is actually significantly faster on some
726    machines.  The current font used is (mostly) fixed-width, but this isn't an
727    inherent limitation - it was just the easiest font data to convert to a
728    usable format.
729
730  + Fix assertion failure due to rounding differences on loading certain .3d
731    files.  (ticket#26)
732
733  + Fix assertion failure when turning on 3D passages if they stick out higher
734    or lower than any station.  (ticket#29)
735
[53f8a93]736  + Fix grid not to disappear when blobs are turned on and blobs are drawn
737    using lines.
738
[94960ad]739  + If a degree sign isn't available in the character set in use, transliterate
740    it to 'dg' rather than skipping it.
741
742  + Fix message which should have been a degree sign but got lost in the format
743    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
744    that bearings in the status bar now have a degree sign after them if they
745    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
746
747  + Fix print dialog to calculate the scale required for "One page" right
748    before it calculates how many pages are required, so we don't end up
749    something other than 1x1 being shown when the user changes settings.
750
751  + Update the calculations for picking a scale and for deciding how many
752    pages are needed to take into account the change in info box height made
753    in 1.2.1.
754
[9704252]755Changes in 1.2.1 (2011-10-04):
[e3c58c3]756
757* Translation updates for US English.
758
759* aven:
760
761  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
762    it now shows colours for dates and errors as well as depths.
763
764  + In the colour key for "colour by date", change "No info" to "Undated".
765
766  + Remove the dark grey background from the colour key and just put a single
767    pixel black border around the colours.  This is more in keeping with the
768    other controls, and means the colours are now on a black background so more
769    visually similar to the survey legs.
770
771  + Move the colour key's "Undated"/"Not in loop" entry down a little to
772    improve the appearance.  Make each section a pixel taller.
773
[9704252]774  + Allow "Colour by X" to be selected even if there's no data for X or only a
775    single value of X used (the colour key is much smaller in these cases, and
776    does still provide some useful information).
777
778  + Fix incorrect calculation of depth colouring for survey legs which straddle
779    a depth band boundary.
[e3c58c3]780
781  + The scale bar, compass, clino, and colour key now all have right click
[9704252]782    menus which allow related actions to be performed (especially handy in
783    full-screen mode).
[e3c58c3]784
785  + Improve the font used on the survey pane - it now contains the '-'
786    character (so the clino now shows negative angles as negative, and dates
787    in the colour key are now hyphenated).  Also the spacing and alignment
788    are a little better, though still not perfect.
789
790  + PLT file export now handles spaces and control characters in station names
791    by escaping them with '%' as in URLs.
792
793  + Pressing "Enter" on a station in the tree control now centres the view on
794    that station.
795
796  + The scale bar is now cached in an OpenGL display list since it often gets
797    redrawn exactly the same - for example, when rotating, panning, etc.
798
799  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
800    then forces a refresh of the survey pane.  This is intended as a debugging
801    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]802    where a list should have been invalidated (please report if you find such
803    a case as it is a bug).
[e3c58c3]804
[9704252]805  + We now automatically track which OpenGL display lists need to be
806    invalidated on window width or height changes.
[e3c58c3]807
808  + Increase scale bar maximum width from 65% of the window width to 75% as it
809    was in 1.0.x (except that if that would overlap the clino we now reduce
810    that proportion down until it reaches 50%).  Make the limit of zooming in
811    the same as in 1.0.x.  (ticket#23)
812
[9704252]813  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
814    the application was fullscreen (the dialog got opened under the main
815    window!)  To work around this, aven would switch out of full screen mode
816    temporarily while showing a dialog.  This case works properly with recent
817    wxGTK, so disable our workaround with versions we know work.  Also, apply
818    the workaround only for wxGTK, not everywhere except on Microsoft Windows
819    as there's no reason to think we need it for other platforms.
[e3c58c3]820
821  + Grey out the "View North" action when we're already viewing North, and
822    similarly for other compass points.
823
824  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
825    info in the "About" dialog.
826
827  + Fix to set the correct filename on the root of the survey tree - previously
828    the filename of the previous file loaded was used!
829
830  + The movie export code now works with newer versions of the FFmpeg libraries
831    as well as still working with older versions.
832
833  + Fix mixed up messages - the print dialog now says "View" on the left
834    subgroup of controls rather than some unrelated message.
835
836  + On printouts, combine the "Plan View"/"Elevation" info box field with the
837    field which gives the bearing and reduce the height on the info box by the
838    removed field, so it's now 3cm for plans and elevations, as for extended
839    elevations.  Report the tilt angle for tilted elevations which it seems has
840    been missing for ages (it's not in recent 1.0.x either).
841
842  + Tweak the exact positioning of informational text on printouts to look
843    nicer and make better use of the available space.
844
845  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
846    dialog.
847
848  + Make the sign of the tilt angle for printouts consistent with the sign
849    shown by the "clino" in the survey pane.
850
851  + In the "Print" dialog, when in plan view disable the "Plan view" button,
852    and similarly for the "Elevation" button.
853
[9704252]854  + (Microsoft Windows version): Sort out appearance of custom cursors.
855
[e3c58c3]856  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
857
858  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
859    you can't get out again easily, so add code to explicitly check for F11
860    being pressed and toggle full screen.
861
862* (Linux version): Fix the RPM .spec file for where man pages now get installed
863  and package aven.svg and the vim support files.  (Fixes from James Begley)
864
865* "make check" now performs several checks on the translation files.
866
867* More messages are now available to be translated.
868
869* cavern: Fix reporting of ranges of survey coordinates, which was broken by
870  the message handling changes in 1.2.0.
871
872* Fix warning when compiling with GCC.
873
874* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
875  sudo for installing on Unix.
876
877* In the manual, replace the instructions for building from source with a
878  pointer to the clearer instructions in INSTALL.
879
880* In the manual, make it clear that installing with administrator rights
881  also applies to newer platforms than XP.
882
883* doc/TODO.htm: Update.
884
[120c1c6]885Changes in 1.2.0 (2011-09-20):
[b4ac7007]886
887* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
888  English.
889
[9cfcb3f]890* tests/smoke.tst: aven no longer requires an X display for --help or
891  --version, so replace skip of this check with a check that this remains the
892  case.
893
894* We now use the standard .po and .pot file formats for storing translations
895  (rather than the Survex-specific messages.txt format), and then translate
896  these into Survex's .msg format.
897
[b4ac7007]898* (Unix version): Move survex man page to section 7 (since it isn't documenting
899  an actual command).
900
[9cfcb3f]901* (Unix version): Write each generated man page to a temporary file, then
902  atomically rename, to avoid leaving an empty or partial man page behind if
903  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
904  recurrence of that).
905
[b4ac7007]906* (Unix version): Default to installing docs into /usr/share/doc/survex rather
907  than /usr/doc/survex.
908
909* aven:
910
[120c1c6]911  + Fix handling of accented characters in the survey pane.
912
[9cfcb3f]913  + Aven icon redrawn in SVG format - it's now a vector image which looks
914    nicer at larger sizes.
915
[b4ac7007]916  + Explicitly request double-buffering, which seems to be needed for systems
917    with GLX >= 1.3.
918
919  + Fix crash while trying to load certain .3d files.
920
921  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]922    Currently this is disabled in Microsoft Windows builds, pending getting the
923    required libraries set up for building releases.
[b4ac7007]924
925  + Reporting of errors during movie export improved.
926
927  + Force playback speed to "x1" during movie export.
928
929  + Use stock IDs for buttons where appropriate - such buttons may now be
930    rendered with icons on some platforms.
931
[9cfcb3f]932  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
933    ISO8859-1).
934
935  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
936    as it's no longer required with modern versions.
937
938  + Don't redraw the survey on every mouse movement in the survey pane unless
939    the measuring line is (or just was) active.  (ticket #17)
940
[b4ac7007]941* cavern:
942
943  + Drop "non-fatal" from the report of how many errors there were at the end
944    of the run - it just confuses users - we won't even get here if there's a
945    fatal error!
946
[9cfcb3f]947  + Add --3d-version option to allow the user to specify the version of the 3d
948    format to output.  (ticket#21)
949
950* img library:
951
952  + Make the highest and lowest valid values for img_output_version available
953    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
954
[b4ac7007]955* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]956  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]957
[8f9b0b6d]958Changes in 1.1.16 (2011-05-16):
[ecdb631]959
960* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
961  Portuguese, and US English.
962
963* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]964  rather than '->' where these characters are available.
[ecdb631]965
966* (Unix version): Link with -lGL, if it exists, to support linking with gold or
967  GNU ld --as-needed (Debian bug #615781).
968
969* img.c:
970
971  + Fix code typo for IMG_API_VERSION == 0 case.
972
973  + Fix code typo in code used when IMG_HOSTED isn't defined.
974
975* doc/TODO.htm: Remove entries which have now been done.
976
[8f9b0b6d]977* (Microsoft Windows version): aven: We now include all the available
978  translations for messages from wxWidgets, which means that standard widgets
979  will appear translated where available even if Survex messages aren't
980  translated.
981
[f5e3521]982Changes in 1.1.15 (2010-10-15):
[2d16e4e]983
984* aven:
985
986  + In the cavern log window, change the "Rerun" button to "Reprocess" to
987    follow terminology in manual and elsewhere.  Fixes ticket#15.
988
989  + When displaying output from cavern, don't update the window after every
990    line, but only when we don't have data from cavern pending.  Hopefully
991    addresses ticket#12.
992
993  + If we aren't using GL_POINTS for blobs, draw them using a series of
994    abutting lines rather than with gluDisk which is faster and gives a
995    consistent shape.
996
997  + Check whether blobs and crosses actually render correctly as points/point
998    sprites, and if they don't, fall back to drawing them with lines.  The
999    best method is cached on disk, and rechecked automatically if the graphics
1000    hardware is changed or the drivers upgraded.
1001
1002  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1003    though, so we still enable USE_FNT by default).
1004
1005  + Don't offer "All files" wildcard in presentation save dialog.
1006
1007  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1008    more places.
1009
1010  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1011    when running cavern from aven.  Fixes ticket#11.
1012
1013* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1014
1015* diffpos: Handle files with duplicate labels in better - extend generates
1016  duplicate labels when it breaks a loop.
1017
1018* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1019
1020* New v7 of .3d format which stores survey dates as number of days since
1021  January 1st 1900, so we now support dates from 1900-2078 (rather than
1022  1970-2037) with a smaller file size.  The img API is now versioned - you
1023  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1024  gives the survey dates in days in days1 and days2 instead of as time_t
1025  values in date1 and date2.  Fixes ticket#14.
1026
1027* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1028  former has been the canonical name for some time, with www.survex.com just
1029  redirecting to it.
1030
1031* (Unix version): Use unlocked file I/O if available, which can be much faster
1032  in some cases (we don't need the locking as we don't do multithreaded file
1033  I/O).
1034
1035* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1036  headers.
1037
1038* (Mac version): buildmacosx.sh now works again.
1039
1040* Most tests weren't actually running any testcases (looks like a sh
1041  portability issue).  This is now fixed, and fortunately all tests still pass.
1042
1043* Include the extra .isl translation files for Innosetup in the source archive.
1044
[f9473ab]1045Changes in 1.1.14 (2010-07-26):
1046
1047* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1048
1049* aven:
1050
1051  + After processing survey data, if there were warnings or errors, add a
1052    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1053    were only warnings, also add an "OK" button to allow moving on to viewing
1054    the processed survey data (fixes ticket#13).
1055
1056  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1057
1058  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1059    not the ': ' after), and to make the title for the terminal the
1060    warning/error message.  Avoid false positives by checking that '<line>' is
1061    a number.
1062
1063  + Don't double escape the contents of href and target in links in the cavern
1064    log window.
1065
1066  + Improve handling of the splitter window, fixing behavioural glitches in
1067    various cases.
1068
1069  + Highlight stations matching any current search when a file is loaded.
1070    (ticket#9)
1071
1072  + (Mac version): Fix build issue due to Mac OS X polluting the global
1073    namespace with its own "Point" class.
1074
1075  + (Unix version): The Gnome print dialog has its own preview window so
1076    suppress ours if using the Gnome one.
1077
1078  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1079
1080  + (Microsoft Windows version): Fix handling of a double-click on the survey
1081    tree when built with wxWidgets >= 2.8.11.
1082
1083* cavern: Report relevant file and line number for three warnings which didn't
1084  give them before.
1085
1086* (Unix and Mac versions): configure: Update the wx-config probing code -
1087  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1088  point looking for them now.
1089
1090* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1091  for easy installation.  Update it to work with the latest Survex versions
1092  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1093  private wxWidgets, use 2.8.11 not 2.7.0-1).
1094
1095* manual:
1096
1097  + Correctly capitalise "GTK".
1098
1099  + Note that on Linux we only regularly test builds with the GTK+ version
1100    (change taken from 1.0).
1101
1102* Fixed the cad3d man page, which was an empty file in 1.1.13.
1103
[0bd49eb]1104Changes in 1.1.13 (2010-06-16):
[90d0d71]1105
1106* Say "wxWidgets" instead of "wxWindows" consistently.
1107
[739b92c]1108* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1109
1110* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1111
1112* aven:
1113
[90d0d71]1114  + wxWidgets 2.6.0 or newer is now required.
1115
1116  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1117    work but hasn't been tested recently (all packaged versions of wxWidgets
1118    seem to be Unicode now).
1119
1120  + Fix potential uses of uninitialised variables which may have been causing
1121    occasional glitches when loading a file on start-up.
1122
[e4bfd2f]1123  + Improvements to the handling of the font used for plotting labels and other
1124    text on the survey pane:
1125
1126    - Loading the font file is more efficient.
1127
1128    - Character spacing is improved.
1129
1130    - Default font is now anti-aliased.
[90d0d71]1131
1132  + "About" dialog:
1133
1134    - Add "Copy" button to copy the system info to the clipboard for easier
1135      bug reporting.
1136
1137    - List OpenGL extensions last, since there are usually lots of them with a
1138      modern gfx card.
1139
1140    - Fix 100% CPU usage while the "About" dialog is open.
1141
1142  + Processing .svx files:
1143
1144    - Passing a .svx file on the command line now works better.
[1324d6c]1145
[739b92c]1146    - Put the survey data log window in a splitter in the usual frame rather
1147      than opening a separate frame for it.
1148
[90d0d71]1149    - Auto-scroll the log window until we've reported a warning or error.
1150
1151    - Fix small memory leak.
1152
1153  + The presentation filename now defaults to using the basename of the
1154    currently loaded dataset, but we always prompt before we first save with
1155    such a name.
1156
1157  + Reduce memory usage when saving a screenshot.
1158
[e4bfd2f]1159  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1160    persist the window size (and maximised or fullscreen state) between
1161    invocations.
1162
[90d0d71]1163  + Fix reporting of OpenGL errors.
1164
1165  + Fix glitches when tilting while looking East.
1166
[739b92c]1167  + Added Portuguese and Slovak translations of wxWidgets messages.
1168
[90d0d71]1169* Documentation:
1170
[e4bfd2f]1171  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1172
1173  + Drop the "alternative manual formats" self-extracting zip file - people
1174    will generally just want one of the formats, so downloading several
1175    together isn't very useful.
1176
[90d0d71]1177  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1178
1179  + GPL.htm: Replace HTML version of licence with a link to the version on
1180    the FSF website.
1181
1182  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1183    low level to be of interest to non-developers, and developers can look at
1184    the source code.
1185
1186* (Unix version): configure: New preferred name for specifying wx-config script
1187  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1188
[e4bfd2f]1189* (Linux version): Source RPM package dropped as you can just build an RPM
1190  package from the source tarball.
1191
[739b92c]1192* (Microsoft Windows version): The installer is now created with a newer
1193  version of InnoSetup, which gives a 10% smaller download.
1194
[2e12f8c]1195Changes in 1.1.12 (2007-02-07):
[5940815]1196
1197* aven:
1198
[3db0798]1199  + Remember the window size or maximised/fullscreen state between invocations.
1200
[5940815]1201  + Add options dialog to "Export" similar to the one for "Print".
1202
[6b2113d]1203  + The "number of pages required" in the print dialog now updates when you
1204    change what is to be shown (underground legs/surface legs/station
1205    names/crosses).
1206
[920b066]1207Changes in 1.1.11 (2006-11-25):
1208
1209* Updated Czech, Spanish, and Slovak translations.
1210
[99d8798]1211* (MacOS X version): Assorted OS X specific tweaks and fixes.
1212
[920b066]1213* aven:
[78c67a6]1214
[920b066]1215  + Pick a smaller and clearer font for labels.
[99d8798]1216
[920b066]1217  + Fix character spacing.
[99d8798]1218
[920b066]1219  + Tweak display of bearing and elevation angles to look nicer with
1220    proportional fonts.
[99d8798]1221
[920b066]1222  + Use the title from the 3d (or plt, etc) file for the window title
1223    rather than the filename.
[99d8798]1224
[920b066]1225  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1226
[920b066]1227  + Only consider underground legs when calculating the depth bands and
1228    depth colouring.
[99d8798]1229
[920b066]1230  + Add "Colour by Error".
[99d8798]1231
[920b066]1232  + Add entry for "white" in date and error keys.
[99d8798]1233
[920b066]1234  + When setting the view to a single point, don't change the scale.
[99d8798]1235
[920b066]1236  + If reloading the same file, don't change the view
[99d8798]1237
[920b066]1238  + Fix filetypes selector in open dialog.
[99d8798]1239
[920b066]1240  + Fix the charset we use for aven in certain cases.
[99d8798]1241
[920b066]1242  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1243
[920b066]1244  + Pass wx the full language code to initialise the C library locale.
[99d8798]1245
[920b066]1246  + Fix bug in generating prefix tree view which could lead to a bogus
1247    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1248
[920b066]1249  + "New Presentation" now ensures that the side panel is open
[99d8798]1250
[920b066]1251  + Fix updating of cached opengl lists when the view is reset to the
1252    default.
[99d8798]1253
[920b066]1254* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1255  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1256
[920b066]1257* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1258  specified.  Either/both can be set to ":".
[99d8798]1259
[920b066]1260* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1261
[920b066]1262* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1263
[920b066]1264Changes in 1.1.10 (2006-07-14):
[ac3f376]1265
1266* aven: Clicking on a survey name in the survey tree now highlights it in
1267  the map view.  Double-clicking zooms the view to show the clicked survey
1268  highlighted.  Clicking the root clears the highlighting and double-clicking
1269  the root restores the default view.  To expand/collapse a branch, click
1270  on the "[+]" or "[-]" icon to the left of the survey name.
1271
1272* aven: The measuring line can now measure to anywhere in plan or elevation
1273  view (not just to a station!)  In plan view the horizontal distance and
1274  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1275
[ac3f376]1276* aven: Moving the mouse over a station in the survey view now highlights
1277  that station in the survey tree (though it may not be visible if the
1278  survey(s) it is in aren't expanded).
1279
1280* aven: Clicking on a station to centre the view now moves the mouse pointer
1281  to the new location of the station (except on Mac OS X where this isn't
1282  allowed).
1283
1284* aven: Fix which presentation toolbar buttons are shown as depressed.
1285
1286* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1287
1288* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1289
[920b066]1290Changes in 1.1.9 (2006-07-04):
[6a2594be]1291
1292* (Unix version): Install desktop files for aven and svxedit contributed to the
1293  Ubuntu package by Phil Bull, and corresponding pixmaps.
1294
1295* Fix img to filter out cross-sections which don't match the subsurvey (if
1296  specified).  The API now returns img_XSECT_END to mark the end of a
1297  passage rather than setting a flag on the last img_XSECT of the passage.
1298
1299* Enhance integration with the vim editor - this can now colour .err files, run
1300  cavern from vim and parse error output, and run aven from vim.  Tweak the
1301  existing vim mode for .svx files to fix a few minor bugs and add support for
1302  the new "*data passage" style.
1303
1304* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1305  which can't draw large enough blobs for us.
1306
1307* aven: sort out confusion about what encoding everything is in which means
1308  that the distance measured by the measuring line actually gets displayed
1309  and also fixes problems with empty menu items in non-English locales in
1310  some cases.
1311
1312* aven: redraw grey background after a menu is closed over the aven window
1313  with no survey loaded.
1314
1315* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1316
1317* aven: avoid crash on some machines when opening "About" dialog before having
1318  loaded a survey.
1319
1320* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1321
1322* (Unix version): aven: Fix character set handling of cavern output.
1323
1324* cavern: Report an error if a cross-section is specified for a station which
1325  doesn't exist.
1326
1327* Updated French and Italian translations.
1328
1329* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1330  `${prefix}/share/survex'" error.
1331
[6a2594be]1332* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1333  (doesn't affect Survex itself, but other applications which use img.c should
1334  update their copy).
1335
1336* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1337  and later are caught by configure, whereas older wx versions are caught when
1338  trying to compile).
1339
[920b066]1340Changes in 1.1.8 (2006.06.30):
[cd39f67]1341
[c988ae4]1342* Drop support for building with wxWidgets versions prior to 2.4.0
1343  (which was released on 2003-01-07).
1344
[9577fcc]1345* aven: Printing through aven now uses settings from the "[aven]" section
1346  of print.ini, and support for hierarchical sections (using "like=")
1347  has been disabled.
1348
[ecf2d23]1349* aven: Change mouse actions to be compatible with those in Survex 1.0.
1350  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1351  left drag is now smart about not rotating and zooming at the same
1352  time.
1353
[d1628e8e]1354* aven: Highlighting stations now happens as you type, and pressing
1355  "Enter" or clicking the "Find" button now pans and zooms to show the
1356  highlighted stations.
1357
[e67ed1b]1358* aven: Left-clicking away from a station now cancels measuring line.
1359
[3ddd351]1360* aven: Setting view to North, South, East, or West is now animated like
1361  the tilt from plan to elevation.
1362
[c988ae4]1363* aven: Fix presentation saving to also write "." for decimal points and
1364  presentation loading to accept either "." or ",".
1365
1366* (Unix version): aven: Add text for all toolbar items so that aven
1367  will work with the Gnome desktop preference for displaying toolbars as
1368  icons with text or just text (wxWidgets needs fixing first though).
1369
1370* (Unix version): aven: Remove the ability to detach the menu bar (yell
1371  if you actually used it and I'll restore it!)
1372
1373* aven: Add "all survey files" option to the "open file" dialog.
1374
[84f1ed1]1375* (MS Windows version): aven: Fix cursor keys to pan survey.
1376
[a884696]1377* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1378
[9fe7af4f]1379* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1380  run by an unprivileged user.
1381
1382* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1383  installer builder we use) and include new installer translations for
1384  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1385
1386* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1387  translations of messages for wxWidgets (the GUI library we use).
1388
[cd39f67]1389* aven: Disable "Highlight exported points" if there aren't any.
1390
[afffec4]1391* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1392  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1393
[38a192d]1394* (Unix version): test suite: fix smoke test to pass even without X running
1395  (it was meant to but the code had a bug).
1396
[5892e08]1397* aven: Check if OpenGL is available and exit cleanly with a helpful error
1398  if it isn't.
1399
[879e9c3]1400* (Unix version): aven: Fix --help and --version to work without a working
1401  X display (provided it's built with wxWidgets 2.5.1 or newer).
1402
[c8f929b]1403* aven: Automatically select the presentation tab of the notebook when the user
1404  selects "New Presentation" or "Open Presentation".
1405
1406* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1407  reset to default view as well).
1408
1409* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1410  empty.
1411
1412* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1413  up and down instead of being passed on and moving the survey.
1414
[9ad92cc]1415* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1416  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1417  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1418
1419* aven: Put a 5mm border around exported SVG files to allow for station markers
1420  and non-zero width lines.
1421
1422* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1423  was turned on.
1424
1425* aven: Actually close the file we're exporting which fixes problems with it
1426  not always being fully written.
1427
[920b066]1428Changes in 1.1.7 (2005.10.18):
[6662d02]1429
1430* cavern: Add validity checking for dates in *date commands (with feature
1431  test in testsuite).  A date entered as just "year" or "year.month" now
1432  becomes a date range for the relevant period (previously it became a single
1433  date near the middle of that period).
[e0c7cd1]1434
[8add4c9]1435* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1436  with MS Windows).
1437
[9f524ee]1438* extend: Default output name for a file called input.3d is now input_extend.3d
1439  rather than just extend.3d (which was annoying if you wanted to extend
1440  several surveys in the same directory).
1441
[185d793]1442* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1443  our check for them to include that knowledge.
[185d793]1444
[3515947]1445* aven: Regenerate depth bar if user switches to/from metric units.
1446
[1235f9b]1447* aven: Don't clear the "there" mark just because the mouse pointer has
1448  moved off a station.
1449
[4299674]1450* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1451  same directory (since that's where we then try to load it from).
[4299674]1452
[60dbe70]1453* aven: Fix labelling of date colouring on 32 bit platforms.
1454
[125c9ea]1455* aven: If "colour by date" is on and we load a survey with no date info
1456  (or all surveyed on the same date) then set "colour by none".
1457
[ec58e3d3]1458* aven: Make the error dialog modal and remove a signal handler once it
1459  has fired to prevent endless (or seemingly endless) cascades of error
1460  dialogs.
1461
[8add4c9]1462* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1463  if a survey file with only one station in is loaded.
1464
[6662d02]1465* aven: Fix problems with indicators disappearing when we're drawing
1466  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]1467  introduced in 1.1.6).
[6662d02]1468
[b65c13f]1469* (Unix version): aven: Really stop setting extra toolbar margin when using
1470  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1471  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1472
[17cce5f]1473* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1474  we've been compiled with, and which GTK+/Motif version where appropriate.
1475
[affaeee]1476* (Unix version): Fixed build on Fedora Core 3.
1477
[618b01f]1478* documentation: Updates to 3d file format specification from Mike McCombe.
1479
[920b066]1480Changes in 1.1.6 (2005.10.10):
[7e01c87]1481
1482* (MS Windows version): Distribution is about a third smaller than 1.1.5
1483  (mostly because mingwm10.dll is no longer required).
1484
[b88b171]1485* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1486  it, showing cavern's output in a window (with errors and warnings clickable
1487  to load the offending file into an editor), and then loading the resulting
1488  3d file.
1489
[7e01c87]1490* aven: Added "Colour by Date" option.
1491
1492* aven: Disable "Colour by Depth" option if there's no elevation variation.
1493
1494* aven: Don't crash if trying to load a survey with no elevation variation.
1495  Instead turn off depth colouring.
1496
[8ea82aa]1497* aven: Export as HPGL added.
1498
[887c26e]1499* aven: Improved update of mouse coordinates and measuring line (thanks to
1500  Martin Green).
1501
[7c29c976]1502* aven: Show the coordinates of either the mouse pointer or the nearest
1503  survey station to it (if there is one near enough).  Showing both was
1504  confusing and meant the status bar overflowed on smaller displays.
1505
[7e01c87]1506* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]1507
[7e01c87]1508* aven: Don't lock "flat" surveys which aren't extended elevations - a
1509  flat survey with LRUD data isn't flat any more!
1510
1511* aven: When we have to draw blobs and crosses the slow way (because the
1512  graphics hardware doesn't support the fast way), draw them so that they
1513  should appear at the correct depth into the 3D scene instead of on top
1514  of everything else.
1515
1516* aven: Make "play presentation backwards" icon green to match the other
1517  presentation icons.
1518
1519* (MS Windows version): aven: Mouse clicks on the survey view now set the
1520  keyboard focus there.
[bd21214]1521
[b46bf92]1522* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1523
[796d7bf]1524* (MS Windows version): aven: Fix redrawing of measuring line.
1525
[7e01c87]1526* cavern: Store dates for img_XSECT.
1527
1528* cavern: Fixed small one-off memory leak if you specify -o more than once.
1529
[b88b171]1530* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1531  language to use for messages.
1532
[7c29c976]1533* (MS Windows version): "Print" on a 3d file now prints through aven rather
1534  than the separate printer driver (Unix has done this for some time).
1535
[8ea82aa]1536* Removed old printer drivers.
1537
[7e01c87]1538* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1539  to write a file format version which doesn't support it.
[8ea82aa]1540
[920b066]1541Changes in 1.1.5 (2005.09.20):
[106cfdf]1542
1543* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1544
[4ba80e0]1545* aven: Make blobs round like they are in Survex 1.0.
1546
1547* aven: If the graphics drivers don't support drawing blobs using OpenGL
1548  point markers, fall back to drawing filled circles.
1549
[95ce35f]1550* aven: If the graphics drivers support it, draw crosses as texture mapped
1551  OpenGL point markers which is much faster.
[90d0d71]1552
[95ce35f]1553* aven: Cross size increased to match Survex 1.0.
1554
[cd78148]1555* aven: We must update which blobs are displayed if display of surface or
1556  underground legs is toggled.
1557
[f5627353]1558* cavern: Fix handling of a *solve followed by survey data, none of which is
1559  attached to the previous data.
1560
[dfe4a520]1561* cavern: Fixed "No survey data" error when a *solve is followed by another
1562  *solve (or the implicit solve at the end of processing) with no data between
1563  them.
1564
[920b066]1565Changes in 1.1.4 (2005.09.19):
[4855072]1566
1567* aven: Added Aven's icon to the "About" dialog.
1568
1569* aven: Use localised character for the decimal point (e.g. "," in most
1570  continental European countries).
1571
1572* aven: Previously the survey tree would get focus and then take keypresses
1573  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1574  operate on the cave, and transfer the input focus across when we do.
1575
1576* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1577
1578* aven: Speed up intialisation by delaying creation of OpenGL lists until
1579  they're needed.
1580
1581* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1582
1583* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1584
1585* aven: Reworded "Restore Default Settings" as "Restore Default View".
1586
1587* (Unix version): aven: Set sensible default margins for printing and preserve
1588  any margin values the user specifies between runs (previously margins
1589  defaulted to 0 each time aven was run).
1590
1591* Documentation: Document *DATA PASSAGE in the manual.
1592
[920b066]1593Changes in 1.1.3 (2005.09.07):
[0e558e5]1594
1595* (Microsoft Windows version): Fixed build problems.
1596
1597* cavern: Allow OMIT character (-) for left/right/up/down.
1598
1599* aven: Remove an unnecessary menu separator.
1600
1601* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1602
1603* aven: Make the tooltip for "Hide" show the number of found stations.
1604
1605* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1606
1607* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1608  when there's a presentation loaded.
1609
1610* aven: Make entrances green in side panel tree list to match green blobs used
1611  in cave view.
1612
1613* aven: Don't show surface labels if we're not showing surface data, etc.
1614
1615* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1616  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1617  existing users are happy, but don't advertise it.
1618
1619* aven: Normalise filename by adding any extension used, and use the normalised
1620  filename for file history and window title.
1621
1622* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1623  as the toolbar buttons already have a sensible margin - the extra margin is
1624  only needed with GTK1.2.
1625
1626* aven: Fix handling of plumb legs in tube model.
1627
1628* aven: Fixed swapped L and R in tube model.
1629
1630* extend: Preserve UD cross-section information in extended elevation.
1631
1632* extend: Add new messages for John Pybus' enhancements.
1633
1634Changes in 1.1.2 (never formally released):
[8faa5d8]1635
1636* Added support for LRUD data in .svx files, in .3d files, and aven can
1637  now load and display it on screen and on printouts.  The ability to "fake"
1638  LRUD data in aven is gone for now but will reappear in some form later.
1639
1640* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1641  fold any desirable missing chasm functionality into aven.
1642
1643* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1644  cursors for each different mouse action to help the user learn what each
1645  does.  Also added cursors for the "compass" and "clino" as well as the
1646  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]1647
[0e558e5]1648* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]1649
1650* tests/smoketest.tst: If X windows is running, check that we can run aven
1651  with --help and --version.
1652
1653* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1654  no results are listed for it.  This revealed that there was a "newline" test
[6225339]1655  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]1656  Fixed all these problems.
1657
1658* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1659  and omitted forward compass/clino readings in Compass DAT files.  Added
1660  a feature test for this to the testsuite.
1661
1662* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]1663  without OpenGL so remove old machinery for this from configure and the
1664  sources.
[8faa5d8]1665
[0e558e5]1666* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]1667
1668* configure: Better output for strcasecmp test.
1669
1670* aven: Fix crosses to work much better.  Not a total fix - their position
1671  in the Z buffer isn't correct and they're rather slow to plot.
1672
1673* aven: Don't regenerate the hittest grid every time the mouse moves while
1674  animating, which solves the mysterious pausing effect (thanks go to Martin
1675  Green for spotting this!)  Also clear all the status bar coordinates when
1676  animating.
1677
1678* aven: Sort out clashing menu shortcuts in some languages.
1679
1680* aven: Fixed compilation problem on x86_64
1681
1682* SPUD: Pruned out stuff which has been done or which is not actually relevant
1683  to this branch.
1684
1685* Merge various changes from 1.0 branch:
1686
1687  + aven: Port over "printing from aven" functionality.
1688
1689  + aven: Port over "export as" functionality,
1690
1691  + Add David Loeffler's vim mode for .svx files.
1692
1693* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]1694
[8faa5d8]1695* aven: Don't use an opengl list for drawing the indicators - we typically make
1696  a new list each time we plot them anyway.
1697
1698* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1699
1700* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]1701  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]1702
1703* configure: Update wxWindows checks to handle newer wx versions.
1704
1705* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
1706  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
1707  for anyone building from CVS).
1708
1709* acinclude.m4: Quote macro name for fix autotools warning.
1710
[4855072]1711* Documentation: "tilt up" is "'" not ",".
[8faa5d8]1712
1713* aven: Add support for mousewheels (to tilt the cave).
1714
1715* aven: Fixed twisted transitions to and from pitches in certain cases.
1716
[0e558e5]1717* aven: Pick a sensible initial window size when the user's desktop is spread
1718  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]1719  better with wx2.4 or earlier as well).
1720
1721* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
1722  contents being visible before any survey is loaded.
1723
1724* aven: Allow a coloured texture to be used
1725
1726* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]1727  is default colour (grey for most systems) not black until a survey is
1728  loaded).
[8faa5d8]1729
1730* aven: Fixed weird "shadowed" icons.
1731
[920b066]1732Changes in 1.1.1 (2004-10-06):
[a7aa27d9]1733
1734* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]1735  startup.
[a7aa27d9]1736
1737* aven: Delay loading the bitmap for the "About" dialog until it is first
1738  needed.  We want start up to be as quick as possible.
1739
[920b066]1740Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]1741
[91e416e]1742* NOTE: Survex 1.1.X releases are development snapshots made available for
1743  the purposes of allowing wider testing and getting more user feedback.  Once
1744  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]1745
[91e416e]1746* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
1747  you're using Windows 95 - these can be obtained from:
1748  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]1749
[91e416e]1750* aven: Solid passages - passage dimensions are currently inferred from
1751  the leg length (pretty effective as you can measure longer legs in
1752  larger passages).  Use of real LRUD data coming soon...
[edb6576]1753
[91e416e]1754* aven: Depth colouring is now continuously varying.
[edb6576]1755
[0580c6a]1756* aven: Colour by depth can now be turned off (and there's the start of a
1757  framework for properly implementing colour by date, error, etc).
1758
[4261983]1759* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
1760  match (? matches any character, * matches any number of characters).
1761
1762* aven: We now use the status bar for coordinates, distances, etc to make
1763  better use of screen space.
[edb6576]1764
[f80077a]1765* aven: Full screen mode (F11).
[edb6576]1766
[6abab84]1767* aven: Perspective view.
1768
[91e416e]1769* aven: Context sensitive cursor shape - needs more work.
[edb6576]1770
[91e416e]1771* aven: Mouse actions changed (hopefully they're now more natural, but
1772  you may find the change disorientating - feedback wanted on this).
[edb6576]1773
[1690fa9]1774* aven: Added "presentations" which allow you to set up fly-through paths
1775  and load/save/run them.
1776
[0580c6a]1777* aven: A presentation can be exported as a movie file.
1778
[045e2af]1779* aven: Added Save screenshot facility.
1780
[c60062d]1781* aven: Depth fogging option.
1782
[0580c6a]1783* aven: Added Smooth Lines option.
1784
1785* aven: Added Textured Walls option.
1786
[f433fda]1787* aven: If a survey has surface legs but no underground legs, default to
1788  showing the surface legs.
1789
[0580c6a]1790* cavern: Dates given to *date are now stored in the 3d file.
Note: See TracBrowser for help on using the repository browser.
