[5c676e2]2
[67a0fc6]3Changes in 1.2.14 (2014-07-??):
[5c676e2]4
[ea59b58]5* aven: You can now quickly zoom to a particular area by holding down the
6  "Shift" key and dragging with the left mouse button to create a rectangular
7  "rubber band box" around the area you wish to zoom to.  If you release the
8  "Shift" key while still dragging, the box is centred on the start point
9  rather than having one corner there.
10
[26e7fa4]11* aven: Fix exporting of passage tubes in elevations and extended elevations
12  - previously up and down were getting drawn across the page!
13
[5c676e2]14* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
15  1.2.13.  (Reported by Brian Clipstone)
16
[515b83e]17* aven: Fix the conditions on which the menu item "Cancel measuring line" is
18  enabled - previously it was hard to actually cancel it via the menu.
19  Reported by Hugh St Lawrence.
20
[5c676e2]21* aven: Fix wx assertion failures when showing hit test debug view on platforms
22  such as 64-bit Linux.
23
[2c5ec88]24* aven: When viewing from above, show "Plan" above the "clino" which indicates
25  the tilt angle (instead of "Elevation -90°").
26
[5c676e2]27* aven: The extended font data now loads faster, and also uses less memory on
28  64-bit platforms.
29
[ea59b58]30* aven: Dragging the vertical divider between the side panel and the 3D view
31  now only updates when you finish the drag, as redrawing continuously just
32  looks clunky except on an ultra-fast machine.
33
[2c5ec88]34* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
35  the space available in the aven UI.
36
[67a0fc6]37* cavern: Add a *cs command to setting the coordinate system for *fix commands
38  and the coordinate system used for processed survey data.
[ea59b58]39
[515b83e]40* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
41  and handle it in the same way as the "DUPLICATE" flag in .svx files.
42
[67a0fc6]43* cavern: Fix handling of the rather contrived case of *fix with no coordinates
44  followed by *solve and then another *fix with no coordinates not to access
45  freed memory.
46
[2c5ec88]47* (Microsoft Windows version): Include dump3d in the installer.
48
[5c676e2]49* Fix a compiler warning.
50
51* Improve test coverage.
52
[0d365be]53Changes in 1.2.13 (2014-05-15):
[acbb5b1]54
[8ccd1d8]55* aven: Fix --print option to wait for printing to happen before exiting
56  (previously it would exit right after opening the print dialog, so you
57  couldn't actually print anything out using it).
58
[acbb5b1]59* aven: Increase the threshold for how close the pointer needs to be to a
60  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
61  Hugh St Lawrence.
62
[0d365be]63* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]64  if increasing the minimum pointer to station threshold helps Hugh's problems
65  with using aven on a touch screen device.
66
[acbb5b1]67* aven: The measuring line was unable to see stations which had just been
68  revealed by toggling surface or underground legs on - this is now fixed.
69
70* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
71  many entries are in each box (toggled by F3).
72
73* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
74  off and back on.
75
76* aven: Create the empty hit-test grid data structure lazily, to reduce start
77  up time a little.
78
79* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
80  and *end commands to instead talk about "survey names".
81
82* cavern: For ages cavern has warned if you reentered a survey, but this
83  warning was suppressed if it occurred at the same line of the same file as
84  the survey was first entered, but this can only happen if you include the
85  same survey file more than once, which isn't a sensible thing to do for a
86  file with actual survey data in (you might reasonably do it to set up survey
87  grade details or something like that).  The warning is now given in this
88  situation too.
89
90* cavern: After 5 warnings about reentering a survey we give up warning about
91  it, but we used to keep reporting where the survey was originally entered -
92  this secondary diagnostic message is now silenced when the main message is.
93
94* (Microsoft Windows version): Compile C code with optimisation on.
95
96* Add the start of a Russian translation, with messages take from therion.
97
98* Minor translation updates to French.
99
100* Fix compiler warning from GCC.
101
102* Testsuite improvements:
103
104  + Test that "..." anon station works.
105
106  + cavern.tst: Check number of errors returned by all testcases which should
107    fail and give an error count.
108
109  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
110
[ad727d8]111Changes in 1.2.12 (2014-04-14):
[46d12e9]112
[63e8642]113* aven: Fix measuring line to show change in altitude rather than altitude
114  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
115  Clipstone.
[46d12e9]116
[ad727d8]117* aven: Fix printing when built with wxWidgets 3.0.
118
119* aven: Several visual improvements to printouts:
120
121  + Move the numbers below the scale bar down a little so that they don't
122    overlap the scale bar ticks.
123
124  + Set the clipping region after we draw the page border and info box to avoid
125    clipping the border in print preview.
126
127  + Tidy up the appearance of the compass and elevation arrow.
128
[63e8642]129* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
130  <http://bugs.debian.org/739332>.
[46d12e9]131
[63e8642]132* aven: Fix to build with older libav where avcodec_free_frame() isn't
133  available.
[46d12e9]134
[ad727d8]135* (Linux version) survex.spec: Update spec file used for building RPM packages.
136
137* (Unix version): Add "Keywords:" entry to .desktop files.
138
139* (Unix version): Enable large file support, mostly to support filing systems
140  which return 64 bit inode values, such as CIFS mounts.
141
[63e8642]142* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
143  rather than any character which is a letter in the current locale.
[46d12e9]144
[63e8642]145* Various translation updates.
[46d12e9]146
[aac3336]147Changes in 1.2.11 (2014-01-28):
[fb941bfd]148
149* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
150  Reported by Kevin Dixon.
151
[aac3336]152* aven: Embed the font data for the first 256 Unicode characters for use in the
153  survey pane into the compiled aven binary to reduce start up overhead.  Any
154  additional characters needed are loaded from a data file only if/when a
155  character >= U+100 is actually needed (as before).
156
[ad3017d]157* aven: Fix display of Unicode characters above 256 when there's a character
158  <= 256 earlier in the same string.
159
[77bdacf]160* aven: Use the actual width of Unicode characters above 256 rather than
161  assuming they are 16 pixels wide.
[ad3017d]162
163* aven: If full screen, don't show the side panel when a new file is opened
164  (e.g. via Ctrl+O).
165
166* aven: Don't give an assertion failure when showing passages for a cave with
167  no vertical extent.  Reported by Jonny Prouty.
168
169* aven: Change terminology in print dialog - say "legend" instead of "info
170  box".
171
172* aven: Add option to show the tilt angle as a percentage gradient.
173
174* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
175  indicators.
176
177* aven: All length units are now translatable.
178
[fb941bfd]179* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
180  will reduce code size and also the number of deprecation warnings about
181  gluErrorString on Mac OS X 10.9.
182
[ad3017d]183* (Microsoft Windows version): aven: Try to work around redraw issues related
184  to the measuring line by redrawing the whole window, which doesn't seem to be
185  measurably slower.
186
187* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
188  give an error rather than quietly ignoring the attempt.
189
[77bdacf]190* cad3d: Make cad3d remap control characters and spaces in station names when
191  generating PLT output in the same way aven does.
192
[ad3017d]193* Various translation updates (particular thanks to Eric Madelaine and Dennis
194  Baudys), including the start of a Bulgarian translation, with messages taken
195  from Therion and elsewhere.
196
197* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
198  GetUserDefaultUILanguage() to get the UI language to use.  For older
199  versions, continue to use GetUserDefaultLCID().
[fb941bfd]200
201* (Microsoft Windows version): The Indonesian translation will now be used
202  automatically when the system language is set to Indonesian.
203
204* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
205  A. Riggs for his work on this.
206
207* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
208  checksum check for the downloaded wx sources.
209
210* Fix a lot of the compiler warnings when building with clang.
211
[ad3017d]212* doc/manual.sgml: Add missing quantities to the list documented as accepted by
213  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
214  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
215  mentioned in list of the units that can be set for them); COUNT (missing
216  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
217  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
218
219* Test suite: Improve test coverage for cavern.
220
[0ecf3b1]221Changes in 1.2.10 (2014-01-15):
222
223* aven: Fix assertion if two mouse buttons are held down at the same time.
224  If dragging with more than one mouse button held down, releasing one causes
225  another which is still held down to take effect.  Reported by Brian
226  Clipstone.
227
[53966d3]228* aven: If we fail to start the external editor when the user clicks on an
229  error or warning from cavern, show an error box.
230
[6f0d0d8]231* aven: If the survey has a title, add it as a top-level <title> element to
232  exported SVG files.
233
234* aven: Escape '<', '>', and '&' in labels in exported SVG files.
235
236* aven: In GPX export, set the <time> element to the datestamp from the 3d
237  file.
238
239* aven: Don't try to write the title if it isn't set or is empty when exporting
240  GPX files.
241
242* aven: Don't bother looking up the printer page setup info when exporting.
243
[0ecf3b1]244* (Microsoft Windows version): aven: Fix crash on "File->Print" or
245  "File->Export" under Windows XP, reported by Brian Clipstone.
246
247* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
248  encoded filename which could occur if run without being asked to load a file
249  on startup.
250
251* (Microsoft Windows version): aven: Compile with optimisation on.
252
253* img library, aven: Although processed CMAP data files are often referred to
254  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
255  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
256  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
257  continue to do so in case anyone is relying on it, but also check for the
258  other extensions.
259
260* img library: Add new "datestamp_numeric" field to struct img giving the
261  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
262  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
263  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
264  timezone wrong.
265
266* img library: Fix my_strcasecmp() to handle top-bit set characters better.
267
[6f0d0d8]268* cavern: Fix NULL pointer dereference when processing Compass DAT file without
269  'SURVEY DATE:'.
[0ecf3b1]270
[6f0d0d8]271* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]272
[6f0d0d8]273* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]274
[53966d3]275* Fix some compiler warnings if built with glibc's fortify source feature
276  enabled.
277
[6b6fb4d]278Changes in 1.2.9 (2014-01-08):
279
280* Document --3d-version in cavern man page and the manual.
281
282* aven: Fix compilation error in movie export code with recent libavi.
283
284* aven: Fix warning on stderr when export a movie as MPEG.
285
286* img library: In non-hosted mode, don't define GETC and PUTC if they're
287  already defined, to allow easy overriding with getc_unlocked() and
288  putc_unlocked() (which are significantly faster on Linux).
289
290* img library: In non-hosted mode, check that int is at least 32 bits,
291  and if not, use long.  In practice, platforms with 16 bit int are mostly
292  obsolete, but it's not hard to be portable here.
293
294* img library: Add test that img.c and img.h compile in non-hosted mode
295  (regression test for issue fixed in 1.2.8).
296
297* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
298
299* Update translations from launchpad and from existing similar messages.
300
301* Fix some compiler warnings.
302
[e1f27c4]303Changes in 1.2.8 (2013-10-29):
[da65891]304
305* cavern: Fix handling of anonymous wall stations ('..' by default) to
306  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
307  Holder.
308
[e1f27c4]309* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]310  statistics when the value gets large.
311
[a4adf09]312* cavern: Eliminate redundant progress message when solving simultaneous
313  equations.
314
[e1f27c4]315* aven: Add a format drop down to the export dialog, and only show fields which
316  are meaningful and supported for the currently selected export format.  The
317  format defaults to that used most recently.  The "Elements" and "View" boxes
318  have been swapped in the print and export dialogs as that layout works much
319  better when the "View" box is hidden.
320
[0056ee1]321* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
322  - now works again.  Reported by Anthony Day.
323
[e1f27c4]324* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
325  this release the projection which the survey coordinates are in defaults
326  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
327  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
328  projection string.  The ability to specify this projection in a better
329  way is coming soon.
330
331* aven: New export options "Origin in centre" and "Full coordinates" - the
332  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
333
334* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
335  time ago, so update references.
336
337* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
338  with wxMSW 2.9.5.  Reported by Brian Clipstone.
339
340* aven: Make right click in an empty presentation mark the current position and
341  open it to edit, instead of crashing.
342
343* aven: Update movie export code to work with latest libav API.  Reported by
344  Sebastian Ramacher.
345
346* aven: Improve reporting of errors during the process of exporting a movie.
347
348* aven: Don't try to close the movie if we aren't producing one.
349
350* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
351
352* aven: Fix to build with wxMSW 2.9.5.
353
354* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
355
356* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
357  ago, so add a new --skencil option to specify this output format.  The old
358  name (--sketch) is still recognised for compatibility.
359
360* cad3d: Make --marker-size work for Skencil and SVG output.
361
362* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]363
[88b54df6]364* img library:
365
[e1f27c4]366  + Fix to work once more when used outside of Survex (missing definition of
367    max() macro and a bad call to free() in img_close() for a file opened for
368    reading).
369
370  + Use lround() instead of round(), and make the tests around whether we use
371    the library function or the our fallback implementation saner.
372
373  + Fix // comments in C code for portability to pre-C99 compilers which don't
374    support these as an extension.
[88b54df6]375
[f807d8bf]376  + Can now be compiled as C++ as well as as C.
377
[e1f27c4]378* (Microsoft Windows version): The installer is now built with a newer version
379  of Innosetup, and includes translations for all the languages which Survex
380  itself has any translations for.
381
382* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
383
384* Minor translation updates.
385
386* tests/Makefile.am: Distribute files for "normal_bad" testcase.
387
[e34bebc]388Changes in 1.2.7 (2013-07-27):
[65d9b6b]389
[e34bebc]390* Add support for anonymous stations, which are indicated by one, two or three
391  separator characters - with the default separator of '.', that means '.',
392  '..', and '...' are anonymous stations.  Single separator ('.' by default)
393  is an anonymous non-wall point, double separator ('..' by default)
394  is an anoymous wall point at the end of an implicit splay), and triple
395  separator ('...' by default) is an anoymous point (with nothing special about
396  the leg).  A new *alias command allows '-' to be mapped to '..' for
397  compatibility with pocket topo: *alias station - ..
[07beaa4]398
[e34bebc]399* New version 8 of the 3d format:
[07beaa4]400
[e34bebc]401  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]402
[e34bebc]403  + New explicit file-wide flag for 'this is an extended elevation', rather
404    than modifying the survey title to indicate this.
[da9d788]405
[e34bebc]406  + The survey prefix is often unchanged from one leg to the next, so use a
407    spare flag to compactly indicate when there's no label change.
[da9d788]408
[e34bebc]409  + The data style of each leg is now stored.
[da9d788]410
[e34bebc]411  + The "processed at" time is stored as seconds since 1970 rather than a
412    human-readable string.
[da9d788]413
[e34bebc]414  + Since 3d v8 features significant changes to the format, the format
415    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]416
[e34bebc]417* img library:
[da9d788]418
[e34bebc]419  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]420
[e34bebc]421  + Handle .pos files containing unnamed stations - don't suck the next line in
422    as the station name, and set img_SFLAG_ANON for them.
[da9d788]423
[e34bebc]424  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
425    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
426    elevation, in place of appending " (extended)" to the title.  Internally we
427    still append this to the title (and remove it upon reading) when writing
428    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
429    explicitly in the file.
[da9d788]430
[e34bebc]431  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]432
[e34bebc]433* aven:
[da9d788]434
[e34bebc]435  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
436    now, and the wx developers consider even 2.8 to be rather long in the
437    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
438    formally dropping support for older versions allows a number of workarounds
439    to be removed from the aven source code.  Also, features deprecated in
440    wxWidgets 2.9 are no longer used in our code.
[da9d788]441
[e34bebc]442  + Don't run incremental search on every key-press, as on a slow machine the
443    short initial search(es) will take a while but not be useful.  Instead only
444    actually run the search when we're told there are no more key-presses
445    queued up.
[da9d788]446
[e34bebc]447  + Implement support for including cross-section information in exported SVG
448    and DXF files (ticket#4).  The DXF export is untested currently.
449
450  + Show splay legs faded by default, with menu options to hide them or show
451    them like other legs.
452
453  + Speed up loading a .3d file with cross-sections by using a map to convert
454    station names to positions.
455
456  + In the cavern log window, don't highlight a file:linenumber if there's no
457    message after it, which avoids highlighting the "Included from" lines
458    wrongly.
459
460  + Fix not to crash when trying to report an error while starting up.
461
462  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
463    the OS X standard shortcut Shift-Command-F (previously we used F11, but
464    that's used by the desktop).
465
466  + Add checks for errors when reading the font file.
[07beaa4]467
[e34bebc]468  + Remove useless extra quoting when invoking vim to show the location of an
469    error from cavern.
[07beaa4]470
[e34bebc]471  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]472
[e34bebc]473  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
474    in the dialog in sync.
[da9d788]475
[e34bebc]476* cavern:
[3dfffa2]477
[e34bebc]478  + Demote errors about invalid dates to warnings, since we've accepted *date
479    for ages without any checks on the value, and so existing datasets
480    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]481
[e34bebc]482  + New *alias command allows '-' to be mapped to '..' for compatibility with
483    pocket topo: *alias station - ..
[07beaa4]484
[e34bebc]485  + We want to warn if there's a clino reading which it would be impossible to
486    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
487    read "93" (it's probably a typo e.g. for "39").  However, the gradient
488    reading from a topofil is typically in the range 0 to 180, with 90 being
489    horizontal.  Really we should allow the valid range to be explicitly
490    specified, but for now we infer it from the zero error - if this is within
491    45 degrees of 90 then we assume the instrument can read between 0 and 180
492    degrees.
[da9d788]493
[e34bebc]494  + If the survey isn't all connected, still run survey tree checks and report
495    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
496    Dixon for the report which highlighted this issue.
[da9d788]497
[e34bebc]498  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]499
[e34bebc]500  + Report column numbers as well as line numbers for some cavern errors and
501    warnings.
[07beaa4]502
[e34bebc]503  + Adjust width of node stats table to fit longest count when there are more
504    than 9999 of a particular order of node.
[07beaa4]505
[e34bebc]506  + If the argument to *include has an opening double quote but the closing
507    double quote is missing, then skip trying to open the file.
[da9d788]508
[e34bebc]509  + Move "Station X referred to just once" warning after non-existent survey
510    check - if both fire, the non-existent survey error is likely to be more
511    relevant.
[da9d788]512
[e34bebc]513  + We no longer follow an error for a bad reading in passage data with a bogus
514    "End of line not blank" error, but instead check the remaining readings on
515    the same line.
[da9d788]516
[e34bebc]517  + We no longer follow an error about OMIT for a required reading with a bogus
518    "End of line not blank" error.
[7f6250a]519
[e34bebc]520  + Report an error if the scale factor in *calibrate is zero - it doesn't make
521    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]522
[e34bebc]523  + Report the parent include files starting from the outermost, as that's more
524    logical when there are multiple levels involved.
[07beaa4]525
[e34bebc]526  + If we were expecting a numeric field and instead get something which starts
527    with '+', '-', or '.' but which isn't a number, then fix the error to
528    include that character in the token reported.
[3dfffa2]529
[e34bebc]530  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
531    first item.
[07beaa4]532
[e34bebc]533* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]534
[e34bebc]535* dump3d:
[07beaa4]536
[e34bebc]537  + Build, install and package dump3d as standard - it's useful for grabbing
538    info from 3d files in scripts.
[07beaa4]539
[e34bebc]540  + Add --show-dates option.
[07beaa4]541
[e34bebc]542  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]543
[e34bebc]544  + Report the data style of legs.
[da9d788]545
[e34bebc]546  + Report if the file is an extended elevation.
547
548  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]549
550* Test suite:
551
552  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
553    expected output so it passes reliably.
554
[e34bebc]555  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
556    'Deleted' stations upon failure are the more natural way round.
557
[07beaa4]558  + Add more testcases, expand some existing testcases, and add expected output
559    for more.
560
[e34bebc]561* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
562  appropriate C and C++ compilers to use, and link mingw build statically to
563  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]564
565* (Unix version): When determining the character set for command-line tools,
566  check environmental variable LANG after LC_ALL and LC_CTYPE.
567
568* When determining the language, check environmental variable LC_ALL before
569  LC_MESSAGES and LANG (but after SURVEXLANG).
570
[e34bebc]571* If we don't find the message file, only give an error if it was specified
[665183c]572  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]573  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
574  settings.
575
576* There are a handful of hard-coded English message strings for reporting
577  errors trying loading message files, etc.  These are all now ASCII, as if we
578  fail trying to open a message file, it's more likely the encoding isn't
579  set correctly.
580
581* Prune strings we are no longer using and are probably unlikely to use again
582  into a new file po_codes_dead, so that translators don't get presented with
583  them to translate.
584
[07beaa4]585* Merge lots of translation updates.  Most translations are now complete or
586  close to complete.
[3dfffa2]587
588* Add start of Indonesian translation from Arief Setiadi Wibowo.
589
[07beaa4]590* Fix various compiler warnings when building from source.
591
[e34bebc]592* Include scripts gdtconvert and gen_img2aven in the source distribution.
593
[c575465]594Changes in 1.2.6 (2012-02-23):
[b081031]595
596* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
597
598* (Microsoft Windows version): Include JPEG images for aven in the installer
599  package (ticket#35).
600
601* cavern: If we have a reference to a station in a non-existent survey, give a
602  helpful error rather than saying the station hasn't been exported from the
603  survey.  (Bug reported by Martin Green via email)
604
605* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
606  Kahler.
607
608* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]609  .gpx file with waypoints for entrances.  This needs libproj so is disabled
610  by default for this release - to enable it install the development stuff for
611  libproj and build survex with:
612
613      make FINDENTRANCES=findentrances
614      make install FINDENTRANCES=findentrances
[b081031]615
616* dump3d: Add support for showing img_ERROR_INFO items.
617
618* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
619
620* Incorporate a French translation from launchpad I'd previously copied the
621  English version of by mistake.  Attempt to correct mistranslation of "survey
622  file".
623
[685116f]624Changes in 1.2.5 (2012-01-03):
625
626* aven:
627
628  + The survey tree in the left panel is now in sorted order once more.
629
630  + No longer fails with an assertion if used for a long time (we were leaking
631    an OpenGL list each time one had to be regenerated).
632
633  + Now builds with newer FFmpeg library.
634
635  + Draw measuring line in front of the indicators rather than behind them.
636
637  + Loading a new file (or reloading the current one) no longer invalidates
638    the OpenGL lists for the compass and clino, so will be a fraction faster.
639
640* Improve handling of attempts to look up translated messages before the
641  message subsystem is fully initialised (which only happens if there's an
642  error early on).
643
644* Improve the survex(7) man page text, and fix it to be marked as section 7 in
645  the man page source as well as in the filename.
646
[f15ca67f]647Changes in 1.2.4 (2012-01-01):
648
649* aven:
650
651  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
652    initialised, which doesn't cause problems in some machines, but causes aven
653    to abort on others.  This is now fixed, and there's a check in place to
654    help avoid similar issues in future. (ticket#34)
655
656  + Always use metres or feet for the depth colour key, and chose a consistent
657    precision by looking at the depth range. (ticket#30)
658
659  + Show the depth units below the colour bar rather than after every value.
660
661  + When zooming way in, stay in metres rather than switching to cm.
662
663  + On the scale bar, say “1 mile” rather than “1 miles”.
664
665* Translation updates for Catalan, French and Slovak.
666
[5b9942e]667Changes in 1.2.3 (2011-12-31):
668
669* Fix to build with wxWidgets 2.9.2.
670
671* (Mac OS X version):
672
673  + Processing .svx files from aven now works.
674
675  + Remove spurious blank lines from the licence text in "Get Info".
676
677  + Don't create the help menu at all, as it is empty (because the "About"
678    entry goes elsewhere) and sometimes seems to appear in the UI.
679
680  + INSTALL.OSX: Update to reflect current status.
681
682* aven:
683
684  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
685
686  + Improvements to text plotted on the survey pane:
687
688    - Support plotting Unicode character points > 256 by lazily loading the
689      data for them from the font file and plotting them with a direct call to
690      glBitmap(), which is slower but doesn't require a display list per
691      character.
692
693    - Adjust the spacing from fixed width to putting a one pixel gap either
694      side of each one character (so two between adjacent glyphs).  Mostly this
695      reduces the horizontal width, but it adds a pixel for characters like "m"
696      and two in a few cases.
697
698    - Fix .pixelfont file generation to correctly handle characters wider than
699      8 pixels.
700
701  + Fix expected cross shape so don't always reject using texture mapping to
702    draw crosses.
703
[3ea0178]704  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
705    as those consisting of just one.  Previously we would trip over the empty
706    tube later.  Such tubes can for example be created by extend if a splay shot
707    is the start or end of a tube.
708
[5b9942e]709  + Make the green colour used for entrances in the survey tree the same
710    (slightly darker than before) green used for the entrance blobs.
711
712  + Report the version of the library we're actually running with if built
713    against wx >= 2.9.2.  Make it clear that the version reported is the
714    version *built* with for wx < 2.9.2.
715
[3ea0178]716* extend:
717
718  + Copy the end markers for passage tubes.
[5b9942e]719
[3ea0178]720  + Preserve left and right data for tubes (previously they were set to -1.0
721    which means "no info").
722
723* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
724  was no longer used - it certainly is!
725
726* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
727  messages, and curly single right quote instead of straight ASCII apostrophe.
728  Fall back to using straight ASCII versions if we can't represent them in the
729  current character set.
[5b9942e]730
[3ea0178]731* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]732
733* Test suite:
734
735  + Add test coverage for interleaved diving data.
736
737  + Add testcase for diving data with topofil-style distance.
738
[94960ad]739Changes in 1.2.2 (2011-10-06):
740
741* aven:
742
743  + Replace the textured-mapped font drawing with an approach based on
744    glBitmap.  This doesn't suffer from the character alignment issues which
745    the textured-mapped fonts had, and is actually significantly faster on some
746    machines.  The current font used is (mostly) fixed-width, but this isn't an
747    inherent limitation - it was just the easiest font data to convert to a
748    usable format.
749
750  + Fix assertion failure due to rounding differences on loading certain .3d
751    files.  (ticket#26)
752
753  + Fix assertion failure when turning on 3D passages if they stick out higher
754    or lower than any station.  (ticket#29)
755
[53f8a93]756  + Fix grid not to disappear when blobs are turned on and blobs are drawn
757    using lines.
758
[94960ad]759  + If a degree sign isn't available in the character set in use, transliterate
760    it to 'dg' rather than skipping it.
761
762  + Fix message which should have been a degree sign but got lost in the format
763    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
764    that bearings in the status bar now have a degree sign after them if they
765    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
766
767  + Fix print dialog to calculate the scale required for "One page" right
768    before it calculates how many pages are required, so we don't end up
769    something other than 1x1 being shown when the user changes settings.
770
771  + Update the calculations for picking a scale and for deciding how many
772    pages are needed to take into account the change in info box height made
773    in 1.2.1.
774
[9704252]775Changes in 1.2.1 (2011-10-04):
[e3c58c3]776
777* Translation updates for US English.
778
779* aven:
780
781  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
782    it now shows colours for dates and errors as well as depths.
783
784  + In the colour key for "colour by date", change "No info" to "Undated".
785
786  + Remove the dark grey background from the colour key and just put a single
787    pixel black border around the colours.  This is more in keeping with the
788    other controls, and means the colours are now on a black background so more
789    visually similar to the survey legs.
790
791  + Move the colour key's "Undated"/"Not in loop" entry down a little to
792    improve the appearance.  Make each section a pixel taller.
793
[9704252]794  + Allow "Colour by X" to be selected even if there's no data for X or only a
795    single value of X used (the colour key is much smaller in these cases, and
796    does still provide some useful information).
797
798  + Fix incorrect calculation of depth colouring for survey legs which straddle
799    a depth band boundary.
[e3c58c3]800
801  + The scale bar, compass, clino, and colour key now all have right click
[9704252]802    menus which allow related actions to be performed (especially handy in
803    full-screen mode).
[e3c58c3]804
805  + Improve the font used on the survey pane - it now contains the '-'
806    character (so the clino now shows negative angles as negative, and dates
807    in the colour key are now hyphenated).  Also the spacing and alignment
808    are a little better, though still not perfect.
809
810  + PLT file export now handles spaces and control characters in station names
811    by escaping them with '%' as in URLs.
812
813  + Pressing "Enter" on a station in the tree control now centres the view on
814    that station.
815
816  + The scale bar is now cached in an OpenGL display list since it often gets
817    redrawn exactly the same - for example, when rotating, panning, etc.
818
819  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
820    then forces a refresh of the survey pane.  This is intended as a debugging
821    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]822    where a list should have been invalidated (please report if you find such
823    a case as it is a bug).
[e3c58c3]824
[9704252]825  + We now automatically track which OpenGL display lists need to be
826    invalidated on window width or height changes.
[e3c58c3]827
828  + Increase scale bar maximum width from 65% of the window width to 75% as it
829    was in 1.0.x (except that if that would overlap the clino we now reduce
830    that proportion down until it reaches 50%).  Make the limit of zooming in
831    the same as in 1.0.x.  (ticket#23)
832
[9704252]833  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
834    the application was fullscreen (the dialog got opened under the main
835    window!)  To work around this, aven would switch out of full screen mode
836    temporarily while showing a dialog.  This case works properly with recent
837    wxGTK, so disable our workaround with versions we know work.  Also, apply
838    the workaround only for wxGTK, not everywhere except on Microsoft Windows
839    as there's no reason to think we need it for other platforms.
[e3c58c3]840
841  + Grey out the "View North" action when we're already viewing North, and
842    similarly for other compass points.
843
844  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
845    info in the "About" dialog.
846
847  + Fix to set the correct filename on the root of the survey tree - previously
848    the filename of the previous file loaded was used!
849
850  + The movie export code now works with newer versions of the FFmpeg libraries
851    as well as still working with older versions.
852
853  + Fix mixed up messages - the print dialog now says "View" on the left
854    subgroup of controls rather than some unrelated message.
855
856  + On printouts, combine the "Plan View"/"Elevation" info box field with the
857    field which gives the bearing and reduce the height on the info box by the
858    removed field, so it's now 3cm for plans and elevations, as for extended
859    elevations.  Report the tilt angle for tilted elevations which it seems has
860    been missing for ages (it's not in recent 1.0.x either).
861
862  + Tweak the exact positioning of informational text on printouts to look
863    nicer and make better use of the available space.
864
865  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
866    dialog.
867
868  + Make the sign of the tilt angle for printouts consistent with the sign
869    shown by the "clino" in the survey pane.
870
871  + In the "Print" dialog, when in plan view disable the "Plan view" button,
872    and similarly for the "Elevation" button.
873
[9704252]874  + (Microsoft Windows version): Sort out appearance of custom cursors.
875
[e3c58c3]876  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
877
878  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
879    you can't get out again easily, so add code to explicitly check for F11
880    being pressed and toggle full screen.
881
882* (Linux version): Fix the RPM .spec file for where man pages now get installed
883  and package aven.svg and the vim support files.  (Fixes from James Begley)
884
885* "make check" now performs several checks on the translation files.
886
887* More messages are now available to be translated.
888
889* cavern: Fix reporting of ranges of survey coordinates, which was broken by
890  the message handling changes in 1.2.0.
891
892* Fix warning when compiling with GCC.
893
894* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
895  sudo for installing on Unix.
896
897* In the manual, replace the instructions for building from source with a
898  pointer to the clearer instructions in INSTALL.
899
900* In the manual, make it clear that installing with administrator rights
901  also applies to newer platforms than XP.
902
903* doc/TODO.htm: Update.
904
[120c1c6]905Changes in 1.2.0 (2011-09-20):
[b4ac7007]906
907* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
908  English.
909
[9cfcb3f]910* tests/smoke.tst: aven no longer requires an X display for --help or
911  --version, so replace skip of this check with a check that this remains the
912  case.
913
914* We now use the standard .po and .pot file formats for storing translations
915  (rather than the Survex-specific messages.txt format), and then translate
916  these into Survex's .msg format.
917
[b4ac7007]918* (Unix version): Move survex man page to section 7 (since it isn't documenting
919  an actual command).
920
[9cfcb3f]921* (Unix version): Write each generated man page to a temporary file, then
922  atomically rename, to avoid leaving an empty or partial man page behind if
923  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
924  recurrence of that).
925
[b4ac7007]926* (Unix version): Default to installing docs into /usr/share/doc/survex rather
927  than /usr/doc/survex.
928
929* aven:
930
[120c1c6]931  + Fix handling of accented characters in the survey pane.
932
[9cfcb3f]933  + Aven icon redrawn in SVG format - it's now a vector image which looks
934    nicer at larger sizes.
935
[b4ac7007]936  + Explicitly request double-buffering, which seems to be needed for systems
937    with GLX >= 1.3.
938
939  + Fix crash while trying to load certain .3d files.
940
941  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]942    Currently this is disabled in Microsoft Windows builds, pending getting the
943    required libraries set up for building releases.
[b4ac7007]944
945  + Reporting of errors during movie export improved.
946
947  + Force playback speed to "x1" during movie export.
948
949  + Use stock IDs for buttons where appropriate - such buttons may now be
950    rendered with icons on some platforms.
951
[9cfcb3f]952  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
953    ISO8859-1).
954
955  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
956    as it's no longer required with modern versions.
957
958  + Don't redraw the survey on every mouse movement in the survey pane unless
959    the measuring line is (or just was) active.  (ticket #17)
960
[b4ac7007]961* cavern:
962
963  + Drop "non-fatal" from the report of how many errors there were at the end
964    of the run - it just confuses users - we won't even get here if there's a
965    fatal error!
966
[9cfcb3f]967  + Add --3d-version option to allow the user to specify the version of the 3d
968    format to output.  (ticket#21)
969
970* img library:
971
972  + Make the highest and lowest valid values for img_output_version available
973    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
974
[b4ac7007]975* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]976  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]977
[8f9b0b6d]978Changes in 1.1.16 (2011-05-16):
[ecdb631]979
980* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
981  Portuguese, and US English.
982
983* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]984  rather than '->' where these characters are available.
[ecdb631]985
986* (Unix version): Link with -lGL, if it exists, to support linking with gold or
987  GNU ld --as-needed (Debian bug #615781).
988
989* img.c:
990
991  + Fix code typo for IMG_API_VERSION == 0 case.
992
993  + Fix code typo in code used when IMG_HOSTED isn't defined.
994
995* doc/TODO.htm: Remove entries which have now been done.
996
[8f9b0b6d]997* (Microsoft Windows version): aven: We now include all the available
998  translations for messages from wxWidgets, which means that standard widgets
999  will appear translated where available even if Survex messages aren't
1000  translated.
1001
[f5e3521]1002Changes in 1.1.15 (2010-10-15):
[2d16e4e]1003
1004* aven:
1005
1006  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1007    follow terminology in manual and elsewhere.  Fixes ticket#15.
1008
1009  + When displaying output from cavern, don't update the window after every
1010    line, but only when we don't have data from cavern pending.  Hopefully
1011    addresses ticket#12.
1012
1013  + If we aren't using GL_POINTS for blobs, draw them using a series of
1014    abutting lines rather than with gluDisk which is faster and gives a
1015    consistent shape.
1016
1017  + Check whether blobs and crosses actually render correctly as points/point
1018    sprites, and if they don't, fall back to drawing them with lines.  The
1019    best method is cached on disk, and rechecked automatically if the graphics
1020    hardware is changed or the drivers upgraded.
1021
1022  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1023    though, so we still enable USE_FNT by default).
1024
1025  + Don't offer "All files" wildcard in presentation save dialog.
1026
1027  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1028    more places.
1029
1030  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1031    when running cavern from aven.  Fixes ticket#11.
1032
1033* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1034
1035* diffpos: Handle files with duplicate labels in better - extend generates
1036  duplicate labels when it breaks a loop.
1037
1038* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1039
1040* New v7 of .3d format which stores survey dates as number of days since
1041  January 1st 1900, so we now support dates from 1900-2078 (rather than
1042  1970-2037) with a smaller file size.  The img API is now versioned - you
1043  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1044  gives the survey dates in days in days1 and days2 instead of as time_t
1045  values in date1 and date2.  Fixes ticket#14.
1046
1047* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1048  former has been the canonical name for some time, with www.survex.com just
1049  redirecting to it.
1050
1051* (Unix version): Use unlocked file I/O if available, which can be much faster
1052  in some cases (we don't need the locking as we don't do multithreaded file
1053  I/O).
1054
1055* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1056  headers.
1057
1058* (Mac version): buildmacosx.sh now works again.
1059
1060* Most tests weren't actually running any testcases (looks like a sh
1061  portability issue).  This is now fixed, and fortunately all tests still pass.
1062
1063* Include the extra .isl translation files for Innosetup in the source archive.
1064
[f9473ab]1065Changes in 1.1.14 (2010-07-26):
1066
1067* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1068
1069* aven:
1070
1071  + After processing survey data, if there were warnings or errors, add a
1072    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1073    were only warnings, also add an "OK" button to allow moving on to viewing
1074    the processed survey data (fixes ticket#13).
1075
1076  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1077
1078  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1079    not the ': ' after), and to make the title for the terminal the
1080    warning/error message.  Avoid false positives by checking that '<line>' is
1081    a number.
1082
1083  + Don't double escape the contents of href and target in links in the cavern
1084    log window.
1085
1086  + Improve handling of the splitter window, fixing behavioural glitches in
1087    various cases.
1088
1089  + Highlight stations matching any current search when a file is loaded.
1090    (ticket#9)
1091
1092  + (Mac version): Fix build issue due to Mac OS X polluting the global
1093    namespace with its own "Point" class.
1094
1095  + (Unix version): The Gnome print dialog has its own preview window so
1096    suppress ours if using the Gnome one.
1097
1098  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1099
1100  + (Microsoft Windows version): Fix handling of a double-click on the survey
1101    tree when built with wxWidgets >= 2.8.11.
1102
1103* cavern: Report relevant file and line number for three warnings which didn't
1104  give them before.
1105
1106* (Unix and Mac versions): configure: Update the wx-config probing code -
1107  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1108  point looking for them now.
1109
1110* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1111  for easy installation.  Update it to work with the latest Survex versions
1112  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1113  private wxWidgets, use 2.8.11 not 2.7.0-1).
1114
1115* manual:
1116
1117  + Correctly capitalise "GTK".
1118
1119  + Note that on Linux we only regularly test builds with the GTK+ version
1120    (change taken from 1.0).
1121
1122* Fixed the cad3d man page, which was an empty file in 1.1.13.
1123
[0bd49eb]1124Changes in 1.1.13 (2010-06-16):
[90d0d71]1125
1126* Say "wxWidgets" instead of "wxWindows" consistently.
1127
[739b92c]1128* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1129
1130* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1131
1132* aven:
1133
[90d0d71]1134  + wxWidgets 2.6.0 or newer is now required.
1135
1136  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1137    work but hasn't been tested recently (all packaged versions of wxWidgets
1138    seem to be Unicode now).
1139
1140  + Fix potential uses of uninitialised variables which may have been causing
1141    occasional glitches when loading a file on start-up.
1142
[e4bfd2f]1143  + Improvements to the handling of the font used for plotting labels and other
1144    text on the survey pane:
1145
1146    - Loading the font file is more efficient.
1147
1148    - Character spacing is improved.
1149
1150    - Default font is now anti-aliased.
[90d0d71]1151
1152  + "About" dialog:
1153
1154    - Add "Copy" button to copy the system info to the clipboard for easier
1155      bug reporting.
1156
1157    - List OpenGL extensions last, since there are usually lots of them with a
1158      modern gfx card.
1159
1160    - Fix 100% CPU usage while the "About" dialog is open.
1161
1162  + Processing .svx files:
1163
1164    - Passing a .svx file on the command line now works better.
[1324d6c]1165
[739b92c]1166    - Put the survey data log window in a splitter in the usual frame rather
1167      than opening a separate frame for it.
1168
[90d0d71]1169    - Auto-scroll the log window until we've reported a warning or error.
1170
1171    - Fix small memory leak.
1172
1173  + The presentation filename now defaults to using the basename of the
1174    currently loaded dataset, but we always prompt before we first save with
1175    such a name.
1176
1177  + Reduce memory usage when saving a screenshot.
1178
[e4bfd2f]1179  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1180    persist the window size (and maximised or fullscreen state) between
1181    invocations.
1182
[90d0d71]1183  + Fix reporting of OpenGL errors.
1184
1185  + Fix glitches when tilting while looking East.
1186
[739b92c]1187  + Added Portuguese and Slovak translations of wxWidgets messages.
1188
[90d0d71]1189* Documentation:
1190
[e4bfd2f]1191  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1192
1193  + Drop the "alternative manual formats" self-extracting zip file - people
1194    will generally just want one of the formats, so downloading several
1195    together isn't very useful.
1196
[90d0d71]1197  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1198
1199  + GPL.htm: Replace HTML version of licence with a link to the version on
1200    the FSF website.
1201
1202  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1203    low level to be of interest to non-developers, and developers can look at
1204    the source code.
1205
1206* (Unix version): configure: New preferred name for specifying wx-config script
1207  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1208
[e4bfd2f]1209* (Linux version): Source RPM package dropped as you can just build an RPM
1210  package from the source tarball.
1211
[739b92c]1212* (Microsoft Windows version): The installer is now created with a newer
1213  version of InnoSetup, which gives a 10% smaller download.
1214
[2e12f8c]1215Changes in 1.1.12 (2007-02-07):
[5940815]1216
1217* aven:
1218
[3db0798]1219  + Remember the window size or maximised/fullscreen state between invocations.
1220
[5940815]1221  + Add options dialog to "Export" similar to the one for "Print".
1222
[6b2113d]1223  + The "number of pages required" in the print dialog now updates when you
1224    change what is to be shown (underground legs/surface legs/station
1225    names/crosses).
1226
[920b066]1227Changes in 1.1.11 (2006-11-25):
1228
1229* Updated Czech, Spanish, and Slovak translations.
1230
[99d8798]1231* (MacOS X version): Assorted OS X specific tweaks and fixes.
1232
[920b066]1233* aven:
[78c67a6]1234
[920b066]1235  + Pick a smaller and clearer font for labels.
[99d8798]1236
[920b066]1237  + Fix character spacing.
[99d8798]1238
[920b066]1239  + Tweak display of bearing and elevation angles to look nicer with
1240    proportional fonts.
[99d8798]1241
[920b066]1242  + Use the title from the 3d (or plt, etc) file for the window title
1243    rather than the filename.
[99d8798]1244
[920b066]1245  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1246
[920b066]1247  + Only consider underground legs when calculating the depth bands and
1248    depth colouring.
[99d8798]1249
[920b066]1250  + Add "Colour by Error".
[99d8798]1251
[920b066]1252  + Add entry for "white" in date and error keys.
[99d8798]1253
[920b066]1254  + When setting the view to a single point, don't change the scale.
[99d8798]1255
[920b066]1256  + If reloading the same file, don't change the view
[99d8798]1257
[920b066]1258  + Fix filetypes selector in open dialog.
[99d8798]1259
[920b066]1260  + Fix the charset we use for aven in certain cases.
[99d8798]1261
[920b066]1262  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1263
[920b066]1264  + Pass wx the full language code to initialise the C library locale.
[99d8798]1265
[920b066]1266  + Fix bug in generating prefix tree view which could lead to a bogus
1267    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1268
[920b066]1269  + "New Presentation" now ensures that the side panel is open
[99d8798]1270
[920b066]1271  + Fix updating of cached opengl lists when the view is reset to the
1272    default.
[99d8798]1273
[920b066]1274* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1275  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1276
[920b066]1277* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1278  specified.  Either/both can be set to ":".
[99d8798]1279
[920b066]1280* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1281
[920b066]1282* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1283
[920b066]1284Changes in 1.1.10 (2006-07-14):
[ac3f376]1285
1286* aven: Clicking on a survey name in the survey tree now highlights it in
1287  the map view.  Double-clicking zooms the view to show the clicked survey
1288  highlighted.  Clicking the root clears the highlighting and double-clicking
1289  the root restores the default view.  To expand/collapse a branch, click
1290  on the "[+]" or "[-]" icon to the left of the survey name.
1291
1292* aven: The measuring line can now measure to anywhere in plan or elevation
1293  view (not just to a station!)  In plan view the horizontal distance and
1294  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1295
[ac3f376]1296* aven: Moving the mouse over a station in the survey view now highlights
1297  that station in the survey tree (though it may not be visible if the
1298  survey(s) it is in aren't expanded).
1299
1300* aven: Clicking on a station to centre the view now moves the mouse pointer
1301  to the new location of the station (except on Mac OS X where this isn't
1302  allowed).
1303
1304* aven: Fix which presentation toolbar buttons are shown as depressed.
1305
1306* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1307
1308* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1309
[920b066]1310Changes in 1.1.9 (2006-07-04):
[6a2594be]1311
1312* (Unix version): Install desktop files for aven and svxedit contributed to the
1313  Ubuntu package by Phil Bull, and corresponding pixmaps.
1314
1315* Fix img to filter out cross-sections which don't match the subsurvey (if
1316  specified).  The API now returns img_XSECT_END to mark the end of a
1317  passage rather than setting a flag on the last img_XSECT of the passage.
1318
1319* Enhance integration with the vim editor - this can now colour .err files, run
1320  cavern from vim and parse error output, and run aven from vim.  Tweak the
1321  existing vim mode for .svx files to fix a few minor bugs and add support for
1322  the new "*data passage" style.
1323
1324* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1325  which can't draw large enough blobs for us.
1326
1327* aven: sort out confusion about what encoding everything is in which means
1328  that the distance measured by the measuring line actually gets displayed
1329  and also fixes problems with empty menu items in non-English locales in
1330  some cases.
1331
1332* aven: redraw grey background after a menu is closed over the aven window
1333  with no survey loaded.
1334
1335* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1336
1337* aven: avoid crash on some machines when opening "About" dialog before having
1338  loaded a survey.
1339
1340* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1341
1342* (Unix version): aven: Fix character set handling of cavern output.
1343
1344* cavern: Report an error if a cross-section is specified for a station which
1345  doesn't exist.
1346
1347* Updated French and Italian translations.
1348
1349* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1350  `${prefix}/share/survex'" error.
1351
[6a2594be]1352* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1353  (doesn't affect Survex itself, but other applications which use img.c should
1354  update their copy).
1355
1356* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1357  and later are caught by configure, whereas older wx versions are caught when
1358  trying to compile).
1359
[920b066]1360Changes in 1.1.8 (2006.06.30):
[cd39f67]1361
[c988ae4]1362* Drop support for building with wxWidgets versions prior to 2.4.0
1363  (which was released on 2003-01-07).
1364
[9577fcc]1365* aven: Printing through aven now uses settings from the "[aven]" section
1366  of print.ini, and support for hierarchical sections (using "like=")
1367  has been disabled.
1368
[ecf2d23]1369* aven: Change mouse actions to be compatible with those in Survex 1.0.
1370  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1371  left drag is now smart about not rotating and zooming at the same
1372  time.
1373
[d1628e8e]1374* aven: Highlighting stations now happens as you type, and pressing
1375  "Enter" or clicking the "Find" button now pans and zooms to show the
1376  highlighted stations.
1377
[e67ed1b]1378* aven: Left-clicking away from a station now cancels measuring line.
1379
[3ddd351]1380* aven: Setting view to North, South, East, or West is now animated like
1381  the tilt from plan to elevation.
1382
[c988ae4]1383* aven: Fix presentation saving to also write "." for decimal points and
1384  presentation loading to accept either "." or ",".
1385
1386* (Unix version): aven: Add text for all toolbar items so that aven
1387  will work with the Gnome desktop preference for displaying toolbars as
1388  icons with text or just text (wxWidgets needs fixing first though).
1389
1390* (Unix version): aven: Remove the ability to detach the menu bar (yell
1391  if you actually used it and I'll restore it!)
1392
1393* aven: Add "all survey files" option to the "open file" dialog.
1394
[84f1ed1]1395* (MS Windows version): aven: Fix cursor keys to pan survey.
1396
[a884696]1397* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1398
[9fe7af4f]1399* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1400  run by an unprivileged user.
1401
1402* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1403  installer builder we use) and include new installer translations for
1404  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1405
1406* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1407  translations of messages for wxWidgets (the GUI library we use).
1408
[cd39f67]1409* aven: Disable "Highlight exported points" if there aren't any.
1410
[afffec4]1411* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1412  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1413
[38a192d]1414* (Unix version): test suite: fix smoke test to pass even without X running
1415  (it was meant to but the code had a bug).
1416
[5892e08]1417* aven: Check if OpenGL is available and exit cleanly with a helpful error
1418  if it isn't.
1419
[879e9c3]1420* (Unix version): aven: Fix --help and --version to work without a working
1421  X display (provided it's built with wxWidgets 2.5.1 or newer).
1422
[c8f929b]1423* aven: Automatically select the presentation tab of the notebook when the user
1424  selects "New Presentation" or "Open Presentation".
1425
1426* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1427  reset to default view as well).
1428
1429* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1430  empty.
1431
1432* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1433  up and down instead of being passed on and moving the survey.
1434
[9ad92cc]1435* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1436  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1437  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1438
1439* aven: Put a 5mm border around exported SVG files to allow for station markers
1440  and non-zero width lines.
1441
1442* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1443  was turned on.
1444
1445* aven: Actually close the file we're exporting which fixes problems with it
1446  not always being fully written.
1447
[920b066]1448Changes in 1.1.7 (2005.10.18):
[6662d02]1449
1450* cavern: Add validity checking for dates in *date commands (with feature
1451  test in testsuite).  A date entered as just "year" or "year.month" now
1452  becomes a date range for the relevant period (previously it became a single
1453  date near the middle of that period).
[e0c7cd1]1454
[8add4c9]1455* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1456  with MS Windows).
1457
[9f524ee]1458* extend: Default output name for a file called input.3d is now input_extend.3d
1459  rather than just extend.3d (which was annoying if you wanted to extend
1460  several surveys in the same directory).
1461
[185d793]1462* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1463  our check for them to include that knowledge.
[185d793]1464
[3515947]1465* aven: Regenerate depth bar if user switches to/from metric units.
1466
[1235f9b]1467* aven: Don't clear the "there" mark just because the mouse pointer has
1468  moved off a station.
1469
[4299674]1470* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1471  same directory (since that's where we then try to load it from).
[4299674]1472
[60dbe70]1473* aven: Fix labelling of date colouring on 32 bit platforms.
1474
[125c9ea]1475* aven: If "colour by date" is on and we load a survey with no date info
1476  (or all surveyed on the same date) then set "colour by none".
1477
[ec58e3d3]1478* aven: Make the error dialog modal and remove a signal handler once it
1479  has fired to prevent endless (or seemingly endless) cascades of error
1480  dialogs.
1481
[8add4c9]1482* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1483  if a survey file with only one station in is loaded.
1484
[6662d02]1485* aven: Fix problems with indicators disappearing when we're drawing
1486  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]1487  introduced in 1.1.6).
[6662d02]1488
[b65c13f]1489* (Unix version): aven: Really stop setting extra toolbar margin when using
1490  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1491  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1492
[17cce5f]1493* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1494  we've been compiled with, and which GTK+/Motif version where appropriate.
1495
[affaeee]1496* (Unix version): Fixed build on Fedora Core 3.
1497
[618b01f]1498* documentation: Updates to 3d file format specification from Mike McCombe.
1499
[920b066]1500Changes in 1.1.6 (2005.10.10):
[7e01c87]1501
1502* (MS Windows version): Distribution is about a third smaller than 1.1.5
1503  (mostly because mingwm10.dll is no longer required).
1504
[b88b171]1505* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1506  it, showing cavern's output in a window (with errors and warnings clickable
1507  to load the offending file into an editor), and then loading the resulting
1508  3d file.
1509
[7e01c87]1510* aven: Added "Colour by Date" option.
1511
1512* aven: Disable "Colour by Depth" option if there's no elevation variation.
1513
1514* aven: Don't crash if trying to load a survey with no elevation variation.
1515  Instead turn off depth colouring.
1516
[8ea82aa]1517* aven: Export as HPGL added.
1518
[887c26e]1519* aven: Improved update of mouse coordinates and measuring line (thanks to
1520  Martin Green).
1521
[7c29c976]1522* aven: Show the coordinates of either the mouse pointer or the nearest
1523  survey station to it (if there is one near enough).  Showing both was
1524  confusing and meant the status bar overflowed on smaller displays.
1525
[7e01c87]1526* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]1527
[7e01c87]1528* aven: Don't lock "flat" surveys which aren't extended elevations - a
1529  flat survey with LRUD data isn't flat any more!
1530
1531* aven: When we have to draw blobs and crosses the slow way (because the
1532  graphics hardware doesn't support the fast way), draw them so that they
1533  should appear at the correct depth into the 3D scene instead of on top
1534  of everything else.
1535
1536* aven: Make "play presentation backwards" icon green to match the other
1537  presentation icons.
1538
1539* (MS Windows version): aven: Mouse clicks on the survey view now set the
1540  keyboard focus there.
[bd21214]1541
[b46bf92]1542* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1543
[796d7bf]1544* (MS Windows version): aven: Fix redrawing of measuring line.
1545
[7e01c87]1546* cavern: Store dates for img_XSECT.
1547
1548* cavern: Fixed small one-off memory leak if you specify -o more than once.
1549
[b88b171]1550* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1551  language to use for messages.
1552
[7c29c976]1553* (MS Windows version): "Print" on a 3d file now prints through aven rather
1554  than the separate printer driver (Unix has done this for some time).
1555
[8ea82aa]1556* Removed old printer drivers.
1557
[7e01c87]1558* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1559  to write a file format version which doesn't support it.
[8ea82aa]1560
[920b066]1561Changes in 1.1.5 (2005.09.20):
[106cfdf]1562
1563* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1564
[4ba80e0]1565* aven: Make blobs round like they are in Survex 1.0.
1566
1567* aven: If the graphics drivers don't support drawing blobs using OpenGL
1568  point markers, fall back to drawing filled circles.
1569
[95ce35f]1570* aven: If the graphics drivers support it, draw crosses as texture mapped
1571  OpenGL point markers which is much faster.
[90d0d71]1572
[95ce35f]1573* aven: Cross size increased to match Survex 1.0.
1574
[cd78148]1575* aven: We must update which blobs are displayed if display of surface or
1576  underground legs is toggled.
1577
[f5627353]1578* cavern: Fix handling of a *solve followed by survey data, none of which is
1579  attached to the previous data.
1580
[dfe4a520]1581* cavern: Fixed "No survey data" error when a *solve is followed by another
1582  *solve (or the implicit solve at the end of processing) with no data between
1583  them.
1584
[920b066]1585Changes in 1.1.4 (2005.09.19):
[4855072]1586
1587* aven: Added Aven's icon to the "About" dialog.
1588
1589* aven: Use localised character for the decimal point (e.g. "," in most
1590  continental European countries).
1591
1592* aven: Previously the survey tree would get focus and then take keypresses
1593  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1594  operate on the cave, and transfer the input focus across when we do.
1595
1596* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1597
1598* aven: Speed up intialisation by delaying creation of OpenGL lists until
1599  they're needed.
1600
1601* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1602
1603* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1604
1605* aven: Reworded "Restore Default Settings" as "Restore Default View".
1606
1607* (Unix version): aven: Set sensible default margins for printing and preserve
1608  any margin values the user specifies between runs (previously margins
1609  defaulted to 0 each time aven was run).
1610
1611* Documentation: Document *DATA PASSAGE in the manual.
1612
[920b066]1613Changes in 1.1.3 (2005.09.07):
[0e558e5]1614
1615* (Microsoft Windows version): Fixed build problems.
1616
1617* cavern: Allow OMIT character (-) for left/right/up/down.
1618
1619* aven: Remove an unnecessary menu separator.
1620
1621* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1622
1623* aven: Make the tooltip for "Hide" show the number of found stations.
1624
1625* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1626
1627* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1628  when there's a presentation loaded.
1629
1630* aven: Make entrances green in side panel tree list to match green blobs used
1631  in cave view.
1632
1633* aven: Don't show surface labels if we're not showing surface data, etc.
1634
1635* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1636  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1637  existing users are happy, but don't advertise it.
1638
1639* aven: Normalise filename by adding any extension used, and use the normalised
1640  filename for file history and window title.
1641
1642* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1643  as the toolbar buttons already have a sensible margin - the extra margin is
1644  only needed with GTK1.2.
1645
1646* aven: Fix handling of plumb legs in tube model.
1647
1648* aven: Fixed swapped L and R in tube model.
1649
1650* extend: Preserve UD cross-section information in extended elevation.
1651
1652* extend: Add new messages for John Pybus' enhancements.
1653
1654Changes in 1.1.2 (never formally released):
[8faa5d8]1655
1656* Added support for LRUD data in .svx files, in .3d files, and aven can
1657  now load and display it on screen and on printouts.  The ability to "fake"
1658  LRUD data in aven is gone for now but will reappear in some form later.
1659
1660* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1661  fold any desirable missing chasm functionality into aven.
1662
1663* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1664  cursors for each different mouse action to help the user learn what each
1665  does.  Also added cursors for the "compass" and "clino" as well as the
1666  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]1667
[0e558e5]1668* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]1669
1670* tests/smoketest.tst: If X windows is running, check that we can run aven
1671  with --help and --version.
1672
1673* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1674  no results are listed for it.  This revealed that there was a "newline" test
[6225339]1675  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]1676  Fixed all these problems.
1677
1678* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1679  and omitted forward compass/clino readings in Compass DAT files.  Added
1680  a feature test for this to the testsuite.
1681
1682* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]1683  without OpenGL so remove old machinery for this from configure and the
1684  sources.
[8faa5d8]1685
[0e558e5]1686* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]1687
1688* configure: Better output for strcasecmp test.
1689
1690* aven: Fix crosses to work much better.  Not a total fix - their position
1691  in the Z buffer isn't correct and they're rather slow to plot.
1692
1693* aven: Don't regenerate the hittest grid every time the mouse moves while
1694  animating, which solves the mysterious pausing effect (thanks go to Martin
1695  Green for spotting this!)  Also clear all the status bar coordinates when
1696  animating.
1697
1698* aven: Sort out clashing menu shortcuts in some languages.
1699
1700* aven: Fixed compilation problem on x86_64
1701
1702* SPUD: Pruned out stuff which has been done or which is not actually relevant
1703  to this branch.
1704
1705* Merge various changes from 1.0 branch:
1706
1707  + aven: Port over "printing from aven" functionality.
1708
1709  + aven: Port over "export as" functionality,
1710
1711  + Add David Loeffler's vim mode for .svx files.
1712
1713* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]1714
[8faa5d8]1715* aven: Don't use an opengl list for drawing the indicators - we typically make
1716  a new list each time we plot them anyway.
1717
1718* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1719
1720* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]1721  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]1722
1723* configure: Update wxWindows checks to handle newer wx versions.
1724
1725* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
1726  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
1727  for anyone building from CVS).
1728
1729* acinclude.m4: Quote macro name for fix autotools warning.
1730
[4855072]1731* Documentation: "tilt up" is "'" not ",".
[8faa5d8]1732
1733* aven: Add support for mousewheels (to tilt the cave).
1734
1735* aven: Fixed twisted transitions to and from pitches in certain cases.
1736
[0e558e5]1737* aven: Pick a sensible initial window size when the user's desktop is spread
1738  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]1739  better with wx2.4 or earlier as well).
1740
1741* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
1742  contents being visible before any survey is loaded.
1743
1744* aven: Allow a coloured texture to be used
1745
1746* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]1747  is default colour (grey for most systems) not black until a survey is
1748  loaded).
[8faa5d8]1749
1750* aven: Fixed weird "shadowed" icons.
1751
[920b066]1752Changes in 1.1.1 (2004-10-06):
[a7aa27d9]1753
1754* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]1755  startup.
[a7aa27d9]1756
1757* aven: Delay loading the bitmap for the "About" dialog until it is first
1758  needed.  We want start up to be as quick as possible.
1759
[920b066]1760Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]1761
[91e416e]1762* NOTE: Survex 1.1.X releases are development snapshots made available for
1763  the purposes of allowing wider testing and getting more user feedback.  Once
1764  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]1765
[91e416e]1766* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
1767  you're using Windows 95 - these can be obtained from:
1768  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]1769
[91e416e]1770* aven: Solid passages - passage dimensions are currently inferred from
1771  the leg length (pretty effective as you can measure longer legs in
1772  larger passages).  Use of real LRUD data coming soon...
[edb6576]1773
[91e416e]1774* aven: Depth colouring is now continuously varying.
[edb6576]1775
[0580c6a]1776* aven: Colour by depth can now be turned off (and there's the start of a
1777  framework for properly implementing colour by date, error, etc).
1778
[4261983]1779* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
1780  match (? matches any character, * matches any number of characters).
1781
1782* aven: We now use the status bar for coordinates, distances, etc to make
1783  better use of screen space.
[edb6576]1784
[f80077a]1785* aven: Full screen mode (F11).
[edb6576]1786
[6abab84]1787* aven: Perspective view.
1788
[91e416e]1789* aven: Context sensitive cursor shape - needs more work.
[edb6576]1790
[91e416e]1791* aven: Mouse actions changed (hopefully they're now more natural, but
1792  you may find the change disorientating - feedback wanted on this).
[edb6576]1793
[1690fa9]1794* aven: Added "presentations" which allow you to set up fly-through paths
1795  and load/save/run them.
1796
[0580c6a]1797* aven: A presentation can be exported as a movie file.
1798
[045e2af]1799* aven: Added Save screenshot facility.
1800
[c60062d]1801* aven: Depth fogging option.
1802
[0580c6a]1803* aven: Added Smooth Lines option.
1804
1805* aven: Added Textured Walls option.
1806
[f433fda]1807* aven: If a survey has surface legs but no underground legs, default to
1808  showing the surface legs.
1809
[0580c6a]1810* cavern: Dates given to *date are now stored in the 3d file.
Note: See TracBrowser for help on using the repository browser.
