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