2
3* aven:
4
5  + Put "paddle" placemarker icons on stations in exported KML files, using the
6    same colour coding for entrances, fixed points and exported points as aven
7    does.
8
9  + Implement exporting of survey legs in KML format.
10
11  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
12    values on Windows.
13
14* cavern:
15
16  + Fix use after free after *solve.  This only occurs if a leg between the two
17    exact same stations appears right before and right after the *solve, which
18    is unlikely in real data, but the testsuite has an instance of this.  This
19    was introduced by the repeat leg averaging added in 1.2.17.
20
21  + Fix small memory leak when solving network.  This doesn't really matter
22    when solving at the end of processing as cavern will exit after that, but
23    if *solve is used we continue processing after solving.
24
25* Remove compatibility handling for specifying a country variant of a language
26  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
27  changed to the standard "en_US" way back in 2001.  This code was mangling
28  character sets with a "-" in, and is no longer useful.
29
30* Ignore any "@<something>" modifier in the language code.
31
[7027ea1]32Changes in 1.2.20 (2015-06-26):
[0eaf4b1]33
34* aven:
35
[6de8e942]36  + When printing, use the top margin rather than the right margin to calculate
37    the height of the printable area.  In practice, the two values seem to be the
38    same or very similar by default.
[0eaf4b1]39
40  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
41    Maynard.
42
43  + Optimise the size of the about dialog images.
44
[7027ea1]45  + Add support for reading terrain data which isn't in a .zip file.
46
47  + Force a refresh after loading terrain data so that it gets displayed right
48    away.
49
50  + Make checks for terrain data extensions in zip files case insensitive.
[6de8e942]51
52  + If reading terrain data fails, always report an error and never try to
53    display it.
54
55* cavern: Allow clino readings in diving style data, suggested by Andrew
56  Atkinson.  Currently these readings are ignored, but a future version will
57  check that they're consistent with the angle given by the depth gauge and
58  tape, and perform suitable averaging.
59
[0eaf4b1]60* Remove lingering traces of svxedit.
61
62* configure: Fix to allow compiling without libav/ffmpeg, as was possible
63  before 1.2.19.
64
65* (Unix version): Install the filetype and aven application icons under
66  /usr/share/icons/hicolor, which is where they're expected to be these days.
67
68* (Unix version): Add %f to Exec in survex-aven.desktop.
69
70* (Mac OS X version): Remove useless extra copy of about box images from OS X
71  disk image.
72
[6de8e942]73* (Mac OS X version): Only ship one copy of each of the translations.
74
[0eaf4b1]75* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
76  libav features we don't use.
77
78* (Microsoft Windows version): Reduce the size of the aven binary by disabling
79  a load of libav features we don't use.
80
81* (Microsoft Windows version): Update message files to fix a missing Chinese
82  message in the installer.
83
[1dc99d1]84Changes in 1.2.19 (2015-06-18):
[f96ac93]85
86* aven:
87
88  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
89    the exported file in 1.2.18.
90
[2dac61e1]91  + Add exporting to Survex .pos format.
92
[4b67f71]93  + If the measuring line isn't currently active, pressing "Escape" will now
94    exit full screen mode.
95
96  + (Mac OS X version): Change the shortcut for full screen mode to be the
97    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
98    using since 1.2.7).
[2dac61e1]99
[f96ac93]100  + (Mac OS X version): When we centre the view on the station this can
101    generate a mouse move event, so clear the variable which says we are
102    dragging before we process a left click on a station.  This avoids random
103    rotations of the survey when clicking on a station, reported in #47 by Hugh
[2dac61e1]104    St. Lawrence.
[f96ac93]105
106  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
107    icons from being rescaled and looking fuzzy.
108
109  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
110    toolbar icons from being rescaled, but which requires an unreleased version
111    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
112
113  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
114    the top of the screen, since we can't seem to display the menu bar in this
115    case like we do on other platforms.
116
[739440f]117  + (Mac OS X version): Enable aven's movie export feature.
118
[2dac61e1]119  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
120    support multi-monitor setups.
121
[f96ac93]122  + (Mac OS X version): Silence warning visible when aven is run from a
123    terminal about a missing CFBundleTypeRole.
124
[4b67f71]125  + When reading terrain data from a .zip file, report an error if the .zip
126    file is bad, or if it doesn't contain any terrain data we recognise.
127
[f96ac93]128  + Tweak error message in terrain reading code to distinguish two failure
129    cases.
130
[2dac61e1]131  + Add viewing angles and scale to footer, and shorten some of the other items
132    to make room for this extra information.  (Fixes ticket #52, reported by
133    Erin Lynch)
134
135  + If the footer is wider than the printout width, scale down the font used
136    so that it exactly fits; if the footer is narrower, than space out the
137    items in in so it uses the full width.
[f96ac93]138
139  + If the saved size for aven's window exceeds the current display size
140    (mostly likely because we're now plugged into a smaller monitor), then
141    reduce the size of the window to fit the display.  If the saved size is <
142    (480x320), increase it to at least that, as aven isn't usable in a smaller
143    window.
144
[2dac61e1]145  + Remove crude bodge which tries to pick a nicer initial window size when
146    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
147    with the same size window it had when it was closed, so the initial size is
148    only relevant on the first ever run.
[f96ac93]149
150* Assorted translation updates.  Notably Indonesian is at 100% again.
151
152* Stop trying to catch and report signals.  The only real reason to do it is so
153  we can say "Bug in program detected! Please report this to the authors"
154  before we exit, but when the program crashes that's pretty obvious.  In aven
155  we try to pop up a message box for this message, which may fail due to
156  whatever caused the signal, while with the command line tools there's no
157  great benefit over just letting the shell report the signal.
158
[4b67f71]159* Use pkg-config to probe for libav and proj, which sorts out the correct flags
160  for building on OS X against a static install of libav.
161
[3f02aa4]162Changes in 1.2.18 (2015-06-03):
[2595419]163
[4a8031f]164* aven:
[a5670c7]165
[4a8031f]166  + Add support for reading terrain data (from a zip file containing either an
167    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
168    rendering it as a transparent surface.
[a5670c7]169
[4a8031f]170  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
171    sanely want to perform from the menu.
[a5670c7]172
[4a8031f]173  + Create a "Colour by" submenu of the "View" menu to house the various
174    colouring options.
[a5670c7]175
[4a8031f]176  + Add "Colour by Gradient" and "Colour by Length".
[a5670c7]177
[4a8031f]178  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
179    which seems more logical, and also allows the dialog to be closed by
180    pressing "Escape".
[a5670c7]181
[38e5701]182  + Destroy any existing clipping region before we write the page footer.
183    Hopefully solves ticket #52, reported by Erin Lynch.
184
[4a8031f]185  + Don't round bearing and tilt angles to integers when printing and
186    exporting.
[a5670c7]187
[38e5701]188  + Add passage export for EPS format.  (Partly addresses ticket #4)
189
190  + Add JSON export.  This should be regarded as experimental, and the format
191    is quite likely to change.
192
[4a8031f]193  + Pressing F6 now toggles the display of rendering stats, currently FPS
194    (Frames Per Second) and the number of triangles in the terrain mesh.
[a5670c7]195
[4a8031f]196  + Add a menu item and toolbar button to show the cavern log window if the
197    currently shown survey data was processed by aven.  Reported by Hugh St
198    Lawrence in #47, and by Dave Clucas and others previously on the list.
199
200  + Add "Save Log" button to Aven's cavern log window.
201
202  + In cavern log window, highlight "error" markers in red and "warning"
203    markers in orange.
204
205  + Rework code to read cavern's output.  In particular, we no longer mix
206    buffered and non-buffered system calls.
207
208  + Aven's support for reading colours and font sizes for printouts from
209    print.ini has never worked - the contents of the ini files are ignored due
210    to a bug which has been there since the code was added in 2005 - but nobody
211    has ever complained.  So just strip out that code entirely - we should
212    support setting the colours and font sizes, but a GUI interface for setting
213    them would be better.
214
215  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
216    Gee.
217
218  + Take the width of the messages used above the compass and clino into
219    account when calculating how much space to allow for them - now the labels
220    won't overlap or be cut off in translations where they are long.
221
222  + (Mac OS X version): Attempt to address the size of the toolbar icons.
223
224* cavern:
[0476b10]225
[38e5701]226  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
227    susscorfa).
228
[4a8031f]229  + Use the currently set units when outputting measurements in warnings,
[38e5701]230    errors, and the stats at the end of the run.  Requested by Bill Gee.
[4a8031f]231
232  + Include column number when a *include file isn't found.
233
234  + Show 'error' in front of error messages, like we show 'warning' in front of
235    warnings.  Fixes #48, reported by Wookey.
236
237  + Increase the threshold for warning that fore and back measurements differ
238    from 2 SDs to 3 SDs.
239
240* findentrances: If the 3d file specifies the coordinate system, use it.
241
242* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
243  would be nice to have, svxedit doesn't really offer that, and it looks ugly
244  in a modern desktop.
[a5670c7]245
[dd65182]246* If we run out of memory while reading a processed survey data file, include
247  the filename in the error message.
248
[4a8031f]249* Many translation updates - notably Indonesian and Russian are now the two
250  most complete translations.
[dd65182]251
[4a8031f]252* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
[dd65182]253
[4a8031f]254* Transliterate gradient and infinity symbols if the current character set
255  lacks them.
[dd65182]256
[4a8031f]257* Add SVG version of .plt icon.
258
259* Manual:
260
261  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
262    highlighting that the previous list was incomplete.
263
264  + Document averaging of a group of repeated readings.
[dd65182]265
[4a8031f]266  + Add a link to the sample data from the manual.
[dd65182]267
[4a8031f]268  + Remove references to contact addresses which are no longer there.  Remove
269    offer to post people floppies, and references to a CD image which isn't
270    available for download.
271
272* Remove non-breaking spaces from the diffpos and extend manual pages, as they
273  actually make the output formatting worse (presumably these used to work
274  around a since-fixed bug in one of the docbook processing tools).
[2595419]275
[4a8031f]276* doc/TODO.htm: Update.
[dd65182]277
[3f02aa4]278* Fix to compile without warnings with 'g++ --std=gnu++11'.
279
[1646310]280Changes in 1.2.17 (2015-02-24):
[a6064e2]281
282* MacOS X version:
283
284  + Update INSTALL file with current status.
285
[e067870]286  + Aven.app now has a custom icon.
[9e053fc]287
[e067870]288  + Add icons for all the filetypes supported.
289
290  + Add Finder actions for .svx, .3d, .plt and .pos files.
[9e053fc]291
292  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
293    currently do this for us.
294
[a6064e2]295  + aven: Fix short-cut for toggling Full Screen mode.
296
297  + aven: Make "About" menu item appear.
298
[9e053fc]299  + aven: Fix "Close" button in about dialog.
300
301  + aven: Make custom cursors black with a white outline to match the standard
302    OS X cursor.
303
[e067870]304  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
305    still doesn't really work like a standard app though - e.g. you can't load
306    files from Finder (instead run svxedit.app and use File->Open), the font
307    size of most menu items is wrong, the icon for the app is the wish icon
308    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
309    probably more.  I'd probably recommend using another editor (OS X comes
310    with TextEdit.app for example).
311
312  + The documentation is now in a "Docs" directory alongside the apps, rather
313    than in the rather less obvious "share/doc/survex" directory.
314
[a6064e2]315  + Default to building for x86_64, since all modern Macs are 64 bit.
316
[9e053fc]317  + Disable use of liblzma when building wxWidgets for OS X, which was
318    preventing the build from working on OS X 10.6.8.
319
320  + Download wx sources from SF via redirecting link.  Thanks to David A.
321    Riggs.
322
323  + buildmacosx.sh: Handle the mount point for the disk image containing a
324    space.
325
[4baea3a]326  + Link with a static build of PROJ for doing coordinate system conversions.
[9e053fc]327
328  + Build wx with --disable-webview to avoid a compilation failure on OS X
329    10.10.1.
330
331  + Use wx-config --cc and --cxx to get the compilers to use for building
332    everything else, as wx adds options to them which otherwise cause linking
333    errors.
334
[4baea3a]335  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
336    smaller download.  This means OS X 10.4 is required, but we probably
337    already need at least 10.5 because that's the minimum version which the
338    wxWidgets build supports by default.
339
[e067870]340  + Remove unused files and copies of files from the diskimage.
341
[a6064e2]342* cavern: If the same leg is repeated consecutively, average the readings and
343  treat as a single leg.
344
[9e053fc]345* dump3d: Report SEPARATOR used by the file being read.
346
347* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
348
349* aven:
350
351  + Greatly reduce flicker when mouse is moved to the top of the screen in full
352    screen mode and the menu bar reappears.
353
354  + For export formats where scaling is supporting, aven now actually uses the
355    scale specified in the export dialog (previously it ignored this and used
356    1:500).
357
358  + Reimplement animation so that it's based on angular change per unit of
359    elapsed time, rather than averaging the time take for the last two scene
360    redraws.  This gives smoother animation in the face of variable load and
361    scene redraw time, and should be more consistent between platforms.
362
363  + Switching to a point of the compass during auto-rotation now jumps straight
364    there rather than the two animations fighting.
365
366  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
367    fast.
368
369  + Disable stepping the rotation angle when animating (previously we only did
370    when rotating).
371
[1646310]372  + Speed up start-up a bit - rather than loading icons from individual PNG
373    files on disk, compile them into the aven binary.
374
375* (Unix version): Add "MimeType" field to desktop files so that file
376  associations work out of the box with modern desktop environments.
377
378* Add start of Hungarian translation from Imre Balogh.
379
380* Merge in many updates to the Russian translation from "vsuhachev".
381
382* Assorted minor updates to other translations.
383
384* Create scalable (SVG) versions of file type icons.
[e067870]385
[a6064e2]386* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
387  we're using git.
388
[1646310]389* tests/: Improve test coverage in a few places:
390
391  + Extend tests of fore and back sights to test calibration of the back
392    compass.
393
394  + Test "Can't calibrate angular and length quantities together" error.
395
396  + Check that "*set names ." works when "." is also the decimal point.
[a6064e2]397
[03d0e8b]398Changes in 1.2.16 (2014-10-17):
[9aa10ad]399
400* aven: Add KML export (stations only currently).
401
[f480117d]402* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
403
[9aa10ad]404* aven: Fix corrupted names in exported files.
405
406* aven: Fix error log window under wxWidgets >= 2.9 to include the system
407  information before the first log message like it does under wxWidgets 2.8.
408
409* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
410
411* tests/: Improve test coverage.
412
[7bd113b]413* Translation updates for many languages, plus the start of translations to
414  Greek and Polish.
[9aa10ad]415
416* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
417  by Martin Sluka.
418
419* Fix warnings when compiling with clang (which is the default compiler on
420  Mac OS X).  Reported by Martin Sluka.
421
[44f51ca]422Changes in 1.2.15 (2014-08-14):
423
424* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
425  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
426  means that we now support all the coordinates systems which Therion does,
427  except for a few which don't have X=East and Y=North.  The documentation
428  for *cs has also been improved.
429
430* aven: We no longer persist full screen mode between runs - it's not a
431  standard behaviour of desktop programs, and it's too easy to go into full
432  screen mode from the menu and then not be able to get out again because you
433  don't know the required key shortcut. (ticket#39)
434
435* aven: When in full screen mode, moving the mouse to the top of the screen now
436  makes the menu bar appear.  This provides a non-shortcut way out of full
437  screen mode, as well as making it easier to perform other operations while in
438  full screen mode.  The current implementation gives an annoyingly flickery
439  transition, but hopefully we can improve this in future. (ticket#39)
440
441* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
442  development), we now call EnableFullScreenView() which improves the full
443  screen mode experience on OS X 10.7 and later.
444
445* img library: Improve documentation for img_ERROR_INFO.
446
447* tests/: Ship some missing .out files and compare.tst.
448
449* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
450  testcase, and extend it to cover a variant of the situation reported as a bug
451  in therion by Bill Gee to the therion list.
452
453* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
454  for the survex package and on tk for the svxedit package.
455
[6a87cce]456Changes in 1.2.14 (2014-07-05):
[5c676e2]457
[1efeb6d]458* img library: Add ability to store a PROJ4 string describing the coordinate
459  system in use in 3d v8 files.
460
461* aven: If the 3d file specifies a coordinate system, then use it for exporting
462  to formats which need to know (currently GPX).  If the input file doesn't
[6a87cce]463  specify the coordinate system, allow the user to enter a PROJ4 string in the
464  export dialog.
[1efeb6d]465
[ea59b58]466* aven: You can now quickly zoom to a particular area by holding down the
467  "Shift" key and dragging with the left mouse button to create a rectangular
468  "rubber band box" around the area you wish to zoom to.  If you release the
469  "Shift" key while still dragging, the box is centred on the start point
470  rather than having one corner there.
471
[26e7fa4]472* aven: Fix exporting of passage tubes in elevations and extended elevations
473  - previously up and down were getting drawn across the page!
474
[5c676e2]475* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
476  1.2.13.  (Reported by Brian Clipstone)
477
[515b83e]478* aven: Fix the conditions on which the menu item "Cancel measuring line" is
479  enabled - previously it was hard to actually cancel it via the menu.
480  Reported by Hugh St Lawrence.
481
[5c676e2]482* aven: Fix wx assertion failures when showing hit test debug view on platforms
483  such as 64-bit Linux.
484
[2c5ec88]485* aven: When viewing from above, show "Plan" above the "clino" which indicates
486  the tilt angle (instead of "Elevation -90°").
487
[5c676e2]488* aven: The extended font data now loads faster, and also uses less memory on
489  64-bit platforms.
490
[ea59b58]491* aven: Dragging the vertical divider between the side panel and the 3D view
492  now only updates when you finish the drag, as redrawing continuously just
493  looks clunky except on an ultra-fast machine.
494
[2c5ec88]495* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
496  the space available in the aven UI.
497
[1efeb6d]498* cavern: Add a *cs command to allow setting the coordinate system for *fix
499  commands, and the coordinate system used for processed survey data.  The
500  latter is now stored in 3d v8 format files.
[ea59b58]501
[515b83e]502* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
503  and handle it in the same way as the "DUPLICATE" flag in .svx files.
504
[6a87cce]505* cavern: If there's more than one *fix command with coordinates, still
506  actually fix the second and subsequent ones, to avoid triggering bogus errors
507  about unconnected surveys.
508
509* cavern: If there's more than one *fix command with coordinates, report the
510  station name of the previous one, plus the file and line number where it was.
511
[67a0fc6]512* cavern: Fix handling of the rather contrived case of *fix with no coordinates
513  followed by *solve and then another *fix with no coordinates not to access
514  freed memory.
515
[1efeb6d]516* dump3d: Report any specified coordinate system.
517
518* doc/3dformat.htm: Update to document how the coordinate system is stored.
519
[2c5ec88]520* (Microsoft Windows version): Include dump3d in the installer.
521
[5c676e2]522* Fix a compiler warning.
523
524* Improve test coverage.
525
[0d365be]526Changes in 1.2.13 (2014-05-15):
[acbb5b1]527
[8ccd1d8]528* aven: Fix --print option to wait for printing to happen before exiting
529  (previously it would exit right after opening the print dialog, so you
530  couldn't actually print anything out using it).
531
[acbb5b1]532* aven: Increase the threshold for how close the pointer needs to be to a
533  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
534  Hugh St Lawrence.
535
[0d365be]536* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]537  if increasing the minimum pointer to station threshold helps Hugh's problems
538  with using aven on a touch screen device.
539
[acbb5b1]540* aven: The measuring line was unable to see stations which had just been
541  revealed by toggling surface or underground legs on - this is now fixed.
542
543* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
544  many entries are in each box (toggled by F3).
545
546* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
547  off and back on.
548
549* aven: Create the empty hit-test grid data structure lazily, to reduce start
550  up time a little.
551
552* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
553  and *end commands to instead talk about "survey names".
554
555* cavern: For ages cavern has warned if you reentered a survey, but this
556  warning was suppressed if it occurred at the same line of the same file as
557  the survey was first entered, but this can only happen if you include the
558  same survey file more than once, which isn't a sensible thing to do for a
559  file with actual survey data in (you might reasonably do it to set up survey
560  grade details or something like that).  The warning is now given in this
561  situation too.
562
563* cavern: After 5 warnings about reentering a survey we give up warning about
564  it, but we used to keep reporting where the survey was originally entered -
565  this secondary diagnostic message is now silenced when the main message is.
566
567* (Microsoft Windows version): Compile C code with optimisation on.
568
569* Add the start of a Russian translation, with messages take from therion.
570
571* Minor translation updates to French.
572
573* Fix compiler warning from GCC.
574
575* Testsuite improvements:
576
577  + Test that "..." anon station works.
578
579  + cavern.tst: Check number of errors returned by all testcases which should
580    fail and give an error count.
581
582  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
583
[ad727d8]584Changes in 1.2.12 (2014-04-14):
[46d12e9]585
[63e8642]586* aven: Fix measuring line to show change in altitude rather than altitude
587  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
588  Clipstone.
[46d12e9]589
[ad727d8]590* aven: Fix printing when built with wxWidgets 3.0.
591
592* aven: Several visual improvements to printouts:
593
594  + Move the numbers below the scale bar down a little so that they don't
595    overlap the scale bar ticks.
596
597  + Set the clipping region after we draw the page border and info box to avoid
598    clipping the border in print preview.
599
600  + Tidy up the appearance of the compass and elevation arrow.
601
[63e8642]602* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
603  <http://bugs.debian.org/739332>.
[46d12e9]604
[63e8642]605* aven: Fix to build with older libav where avcodec_free_frame() isn't
606  available.
[46d12e9]607
[ad727d8]608* (Linux version) survex.spec: Update spec file used for building RPM packages.
609
610* (Unix version): Add "Keywords:" entry to .desktop files.
611
612* (Unix version): Enable large file support, mostly to support filing systems
613  which return 64 bit inode values, such as CIFS mounts.
614
[63e8642]615* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
616  rather than any character which is a letter in the current locale.
[46d12e9]617
[63e8642]618* Various translation updates.
[46d12e9]619
[aac3336]620Changes in 1.2.11 (2014-01-28):
[fb941bfd]621
622* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
623  Reported by Kevin Dixon.
624
[aac3336]625* aven: Embed the font data for the first 256 Unicode characters for use in the
626  survey pane into the compiled aven binary to reduce start up overhead.  Any
627  additional characters needed are loaded from a data file only if/when a
628  character >= U+100 is actually needed (as before).
629
[ad3017d]630* aven: Fix display of Unicode characters above 256 when there's a character
631  <= 256 earlier in the same string.
632
[77bdacf]633* aven: Use the actual width of Unicode characters above 256 rather than
634  assuming they are 16 pixels wide.
[ad3017d]635
636* aven: If full screen, don't show the side panel when a new file is opened
637  (e.g. via Ctrl+O).
638
639* aven: Don't give an assertion failure when showing passages for a cave with
640  no vertical extent.  Reported by Jonny Prouty.
641
642* aven: Change terminology in print dialog - say "legend" instead of "info
643  box".
644
645* aven: Add option to show the tilt angle as a percentage gradient.
646
647* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
648  indicators.
649
650* aven: All length units are now translatable.
651
[fb941bfd]652* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
653  will reduce code size and also the number of deprecation warnings about
654  gluErrorString on Mac OS X 10.9.
655
[ad3017d]656* (Microsoft Windows version): aven: Try to work around redraw issues related
657  to the measuring line by redrawing the whole window, which doesn't seem to be
658  measurably slower.
659
660* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
661  give an error rather than quietly ignoring the attempt.
662
[77bdacf]663* cad3d: Make cad3d remap control characters and spaces in station names when
664  generating PLT output in the same way aven does.
665
[ad3017d]666* Various translation updates (particular thanks to Eric Madelaine and Dennis
667  Baudys), including the start of a Bulgarian translation, with messages taken
668  from Therion and elsewhere.
669
670* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
671  GetUserDefaultUILanguage() to get the UI language to use.  For older
672  versions, continue to use GetUserDefaultLCID().
[fb941bfd]673
674* (Microsoft Windows version): The Indonesian translation will now be used
675  automatically when the system language is set to Indonesian.
676
677* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
678  A. Riggs for his work on this.
679
680* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
681  checksum check for the downloaded wx sources.
682
683* Fix a lot of the compiler warnings when building with clang.
684
[ad3017d]685* doc/manual.sgml: Add missing quantities to the list documented as accepted by
686  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
687  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
688  mentioned in list of the units that can be set for them); COUNT (missing
689  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
690  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
691
692* Test suite: Improve test coverage for cavern.
693
[0ecf3b1]694Changes in 1.2.10 (2014-01-15):
695
696* aven: Fix assertion if two mouse buttons are held down at the same time.
697  If dragging with more than one mouse button held down, releasing one causes
698  another which is still held down to take effect.  Reported by Brian
699  Clipstone.
700
[53966d3]701* aven: If we fail to start the external editor when the user clicks on an
702  error or warning from cavern, show an error box.
703
[6f0d0d8]704* aven: If the survey has a title, add it as a top-level <title> element to
705  exported SVG files.
706
707* aven: Escape '<', '>', and '&' in labels in exported SVG files.
708
709* aven: In GPX export, set the <time> element to the datestamp from the 3d
710  file.
711
712* aven: Don't try to write the title if it isn't set or is empty when exporting
713  GPX files.
714
715* aven: Don't bother looking up the printer page setup info when exporting.
716
[0ecf3b1]717* (Microsoft Windows version): aven: Fix crash on "File->Print" or
718  "File->Export" under Windows XP, reported by Brian Clipstone.
719
720* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
721  encoded filename which could occur if run without being asked to load a file
722  on startup.
723
724* (Microsoft Windows version): aven: Compile with optimisation on.
725
726* img library, aven: Although processed CMAP data files are often referred to
727  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
728  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
729  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
730  continue to do so in case anyone is relying on it, but also check for the
731  other extensions.
732
733* img library: Add new "datestamp_numeric" field to struct img giving the
734  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
735  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
736  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
737  timezone wrong.
738
739* img library: Fix my_strcasecmp() to handle top-bit set characters better.
740
[6f0d0d8]741* cavern: Fix NULL pointer dereference when processing Compass DAT file without
742  'SURVEY DATE:'.
[0ecf3b1]743
[6f0d0d8]744* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]745
[6f0d0d8]746* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]747
[53966d3]748* Fix some compiler warnings if built with glibc's fortify source feature
749  enabled.
750
[6b6fb4d]751Changes in 1.2.9 (2014-01-08):
752
753* Document --3d-version in cavern man page and the manual.
754
755* aven: Fix compilation error in movie export code with recent libavi.
756
757* aven: Fix warning on stderr when export a movie as MPEG.
758
759* img library: In non-hosted mode, don't define GETC and PUTC if they're
760  already defined, to allow easy overriding with getc_unlocked() and
761  putc_unlocked() (which are significantly faster on Linux).
762
763* img library: In non-hosted mode, check that int is at least 32 bits,
764  and if not, use long.  In practice, platforms with 16 bit int are mostly
765  obsolete, but it's not hard to be portable here.
766
767* img library: Add test that img.c and img.h compile in non-hosted mode
768  (regression test for issue fixed in 1.2.8).
769
770* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
771
772* Update translations from launchpad and from existing similar messages.
773
774* Fix some compiler warnings.
775
[e1f27c4]776Changes in 1.2.8 (2013-10-29):
[da65891]777
778* cavern: Fix handling of anonymous wall stations ('..' by default) to
779  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
780  Holder.
781
[e1f27c4]782* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]783  statistics when the value gets large.
784
[a4adf09]785* cavern: Eliminate redundant progress message when solving simultaneous
786  equations.
787
[e1f27c4]788* aven: Add a format drop down to the export dialog, and only show fields which
789  are meaningful and supported for the currently selected export format.  The
790  format defaults to that used most recently.  The "Elements" and "View" boxes
791  have been swapped in the print and export dialogs as that layout works much
792  better when the "View" box is hidden.
793
[0056ee1]794* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
795  - now works again.  Reported by Anthony Day.
796
[e1f27c4]797* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
798  this release the projection which the survey coordinates are in defaults
799  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
800  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
801  projection string.  The ability to specify this projection in a better
802  way is coming soon.
803
804* aven: New export options "Origin in centre" and "Full coordinates" - the
805  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
806
807* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
808  time ago, so update references.
809
810* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
811  with wxMSW 2.9.5.  Reported by Brian Clipstone.
812
813* aven: Make right click in an empty presentation mark the current position and
814  open it to edit, instead of crashing.
815
816* aven: Update movie export code to work with latest libav API.  Reported by
817  Sebastian Ramacher.
818
819* aven: Improve reporting of errors during the process of exporting a movie.
820
821* aven: Don't try to close the movie if we aren't producing one.
822
823* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
824
825* aven: Fix to build with wxMSW 2.9.5.
826
827* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
828
829* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
830  ago, so add a new --skencil option to specify this output format.  The old
831  name (--sketch) is still recognised for compatibility.
832
833* cad3d: Make --marker-size work for Skencil and SVG output.
834
835* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]836
[88b54df6]837* img library:
838
[e1f27c4]839  + Fix to work once more when used outside of Survex (missing definition of
840    max() macro and a bad call to free() in img_close() for a file opened for
841    reading).
842
843  + Use lround() instead of round(), and make the tests around whether we use
844    the library function or the our fallback implementation saner.
845
846  + Fix // comments in C code for portability to pre-C99 compilers which don't
847    support these as an extension.
[88b54df6]848
[f807d8bf]849  + Can now be compiled as C++ as well as as C.
850
[e1f27c4]851* (Microsoft Windows version): The installer is now built with a newer version
852  of Innosetup, and includes translations for all the languages which Survex
853  itself has any translations for.
854
855* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
856
857* Minor translation updates.
858
859* tests/Makefile.am: Distribute files for "normal_bad" testcase.
860
[e34bebc]861Changes in 1.2.7 (2013-07-27):
[65d9b6b]862
[e34bebc]863* Add support for anonymous stations, which are indicated by one, two or three
864  separator characters - with the default separator of '.', that means '.',
865  '..', and '...' are anonymous stations.  Single separator ('.' by default)
866  is an anonymous non-wall point, double separator ('..' by default)
867  is an anoymous wall point at the end of an implicit splay), and triple
868  separator ('...' by default) is an anoymous point (with nothing special about
869  the leg).  A new *alias command allows '-' to be mapped to '..' for
870  compatibility with pocket topo: *alias station - ..
[07beaa4]871
[e34bebc]872* New version 8 of the 3d format:
[07beaa4]873
[e34bebc]874  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]875
[e34bebc]876  + New explicit file-wide flag for 'this is an extended elevation', rather
877    than modifying the survey title to indicate this.
[da9d788]878
[e34bebc]879  + The survey prefix is often unchanged from one leg to the next, so use a
880    spare flag to compactly indicate when there's no label change.
[da9d788]881
[e34bebc]882  + The data style of each leg is now stored.
[da9d788]883
[e34bebc]884  + The "processed at" time is stored as seconds since 1970 rather than a
885    human-readable string.
[da9d788]886
[e34bebc]887  + Since 3d v8 features significant changes to the format, the format
888    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]889
[e34bebc]890* img library:
[da9d788]891
[e34bebc]892  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]893
[e34bebc]894  + Handle .pos files containing unnamed stations - don't suck the next line in
895    as the station name, and set img_SFLAG_ANON for them.
[da9d788]896
[e34bebc]897  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
898    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
899    elevation, in place of appending " (extended)" to the title.  Internally we
900    still append this to the title (and remove it upon reading) when writing
901    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
902    explicitly in the file.
[da9d788]903
[e34bebc]904  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]905
[e34bebc]906* aven:
[da9d788]907
[e34bebc]908  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
909    now, and the wx developers consider even 2.8 to be rather long in the
910    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
911    formally dropping support for older versions allows a number of workarounds
912    to be removed from the aven source code.  Also, features deprecated in
913    wxWidgets 2.9 are no longer used in our code.
[da9d788]914
[e34bebc]915  + Don't run incremental search on every key-press, as on a slow machine the
916    short initial search(es) will take a while but not be useful.  Instead only
917    actually run the search when we're told there are no more key-presses
918    queued up.
[da9d788]919
[e34bebc]920  + Implement support for including cross-section information in exported SVG
921    and DXF files (ticket#4).  The DXF export is untested currently.
922
923  + Show splay legs faded by default, with menu options to hide them or show
924    them like other legs.
925
926  + Speed up loading a .3d file with cross-sections by using a map to convert
927    station names to positions.
928
929  + In the cavern log window, don't highlight a file:linenumber if there's no
930    message after it, which avoids highlighting the "Included from" lines
931    wrongly.
932
933  + Fix not to crash when trying to report an error while starting up.
934
935  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
936    the OS X standard shortcut Shift-Command-F (previously we used F11, but
937    that's used by the desktop).
938
939  + Add checks for errors when reading the font file.
[07beaa4]940
[e34bebc]941  + Remove useless extra quoting when invoking vim to show the location of an
942    error from cavern.
[07beaa4]943
[e34bebc]944  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]945
[e34bebc]946  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
947    in the dialog in sync.
[da9d788]948
[e34bebc]949* cavern:
[3dfffa2]950
[e34bebc]951  + Demote errors about invalid dates to warnings, since we've accepted *date
952    for ages without any checks on the value, and so existing datasets
953    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]954
[e34bebc]955  + New *alias command allows '-' to be mapped to '..' for compatibility with
956    pocket topo: *alias station - ..
[07beaa4]957
[e34bebc]958  + We want to warn if there's a clino reading which it would be impossible to
959    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
960    read "93" (it's probably a typo e.g. for "39").  However, the gradient
961    reading from a topofil is typically in the range 0 to 180, with 90 being
962    horizontal.  Really we should allow the valid range to be explicitly
963    specified, but for now we infer it from the zero error - if this is within
964    45 degrees of 90 then we assume the instrument can read between 0 and 180
965    degrees.
[da9d788]966
[e34bebc]967  + If the survey isn't all connected, still run survey tree checks and report
968    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
969    Dixon for the report which highlighted this issue.
[da9d788]970
[e34bebc]971  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]972
[e34bebc]973  + Report column numbers as well as line numbers for some cavern errors and
974    warnings.
[07beaa4]975
[e34bebc]976  + Adjust width of node stats table to fit longest count when there are more
977    than 9999 of a particular order of node.
[07beaa4]978
[e34bebc]979  + If the argument to *include has an opening double quote but the closing
980    double quote is missing, then skip trying to open the file.
[da9d788]981
[e34bebc]982  + Move "Station X referred to just once" warning after non-existent survey
983    check - if both fire, the non-existent survey error is likely to be more
984    relevant.
[da9d788]985
[e34bebc]986  + We no longer follow an error for a bad reading in passage data with a bogus
987    "End of line not blank" error, but instead check the remaining readings on
988    the same line.
[da9d788]989
[e34bebc]990  + We no longer follow an error about OMIT for a required reading with a bogus
991    "End of line not blank" error.
[7f6250a]992
[e34bebc]993  + Report an error if the scale factor in *calibrate is zero - it doesn't make
994    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]995
[e34bebc]996  + Report the parent include files starting from the outermost, as that's more
997    logical when there are multiple levels involved.
[07beaa4]998
[e34bebc]999  + If we were expecting a numeric field and instead get something which starts
1000    with '+', '-', or '.' but which isn't a number, then fix the error to
1001    include that character in the token reported.
[3dfffa2]1002
[e34bebc]1003  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
1004    first item.
[07beaa4]1005
[e34bebc]1006* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]1007
[e34bebc]1008* dump3d:
[07beaa4]1009
[e34bebc]1010  + Build, install and package dump3d as standard - it's useful for grabbing
1011    info from 3d files in scripts.
[07beaa4]1012
[e34bebc]1013  + Add --show-dates option.
[07beaa4]1014
[e34bebc]1015  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]1016
[e34bebc]1017  + Report the data style of legs.
[da9d788]1018
[e34bebc]1019  + Report if the file is an extended elevation.
1020
1021  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]1022
1023* Test suite:
1024
1025  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
1026    expected output so it passes reliably.
1027
[e34bebc]1028  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
1029    'Deleted' stations upon failure are the more natural way round.
1030
[07beaa4]1031  + Add more testcases, expand some existing testcases, and add expected output
1032    for more.
1033
[e34bebc]1034* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
1035  appropriate C and C++ compilers to use, and link mingw build statically to
1036  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]1037
1038* (Unix version): When determining the character set for command-line tools,
1039  check environmental variable LANG after LC_ALL and LC_CTYPE.
1040
1041* When determining the language, check environmental variable LC_ALL before
1042  LC_MESSAGES and LANG (but after SURVEXLANG).
1043
[e34bebc]1044* If we don't find the message file, only give an error if it was specified
[665183c]1045  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]1046  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
1047  settings.
1048
1049* There are a handful of hard-coded English message strings for reporting
1050  errors trying loading message files, etc.  These are all now ASCII, as if we
1051  fail trying to open a message file, it's more likely the encoding isn't
1052  set correctly.
1053
1054* Prune strings we are no longer using and are probably unlikely to use again
1055  into a new file po_codes_dead, so that translators don't get presented with
1056  them to translate.
1057
[07beaa4]1058* Merge lots of translation updates.  Most translations are now complete or
1059  close to complete.
[3dfffa2]1060
1061* Add start of Indonesian translation from Arief Setiadi Wibowo.
1062
[07beaa4]1063* Fix various compiler warnings when building from source.
1064
[e34bebc]1065* Include scripts gdtconvert and gen_img2aven in the source distribution.
1066
[c575465]1067Changes in 1.2.6 (2012-02-23):
[b081031]1068
1069* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
1070
1071* (Microsoft Windows version): Include JPEG images for aven in the installer
1072  package (ticket#35).
1073
1074* cavern: If we have a reference to a station in a non-existent survey, give a
1075  helpful error rather than saying the station hasn't been exported from the
1076  survey.  (Bug reported by Martin Green via email)
1077
1078* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
1079  Kahler.
1080
1081* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]1082  .gpx file with waypoints for entrances.  This needs libproj so is disabled
1083  by default for this release - to enable it install the development stuff for
1084  libproj and build survex with:
1085
1086      make FINDENTRANCES=findentrances
1087      make install FINDENTRANCES=findentrances
[b081031]1088
1089* dump3d: Add support for showing img_ERROR_INFO items.
1090
1091* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
1092
1093* Incorporate a French translation from launchpad I'd previously copied the
1094  English version of by mistake.  Attempt to correct mistranslation of "survey
1095  file".
1096
[685116f]1097Changes in 1.2.5 (2012-01-03):
1098
1099* aven:
1100
1101  + The survey tree in the left panel is now in sorted order once more.
1102
1103  + No longer fails with an assertion if used for a long time (we were leaking
1104    an OpenGL list each time one had to be regenerated).
1105
1106  + Now builds with newer FFmpeg library.
1107
1108  + Draw measuring line in front of the indicators rather than behind them.
1109
1110  + Loading a new file (or reloading the current one) no longer invalidates
1111    the OpenGL lists for the compass and clino, so will be a fraction faster.
1112
1113* Improve handling of attempts to look up translated messages before the
1114  message subsystem is fully initialised (which only happens if there's an
1115  error early on).
1116
1117* Improve the survex(7) man page text, and fix it to be marked as section 7 in
1118  the man page source as well as in the filename.
1119
[f15ca67f]1120Changes in 1.2.4 (2012-01-01):
1121
1122* aven:
1123
1124  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
1125    initialised, which doesn't cause problems in some machines, but causes aven
1126    to abort on others.  This is now fixed, and there's a check in place to
1127    help avoid similar issues in future. (ticket#34)
1128
1129  + Always use metres or feet for the depth colour key, and chose a consistent
1130    precision by looking at the depth range. (ticket#30)
1131
1132  + Show the depth units below the colour bar rather than after every value.
1133
1134  + When zooming way in, stay in metres rather than switching to cm.
1135
1136  + On the scale bar, say “1 mile” rather than “1 miles”.
1137
1138* Translation updates for Catalan, French and Slovak.
1139
[5b9942e]1140Changes in 1.2.3 (2011-12-31):
1141
1142* Fix to build with wxWidgets 2.9.2.
1143
1144* (Mac OS X version):
1145
1146  + Processing .svx files from aven now works.
1147
1148  + Remove spurious blank lines from the licence text in "Get Info".
1149
1150  + Don't create the help menu at all, as it is empty (because the "About"
1151    entry goes elsewhere) and sometimes seems to appear in the UI.
1152
1153  + INSTALL.OSX: Update to reflect current status.
1154
1155* aven:
1156
1157  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
1158
1159  + Improvements to text plotted on the survey pane:
1160
1161    - Support plotting Unicode character points > 256 by lazily loading the
1162      data for them from the font file and plotting them with a direct call to
1163      glBitmap(), which is slower but doesn't require a display list per
1164      character.
1165
1166    - Adjust the spacing from fixed width to putting a one pixel gap either
1167      side of each one character (so two between adjacent glyphs).  Mostly this
1168      reduces the horizontal width, but it adds a pixel for characters like "m"
1169      and two in a few cases.
1170
1171    - Fix .pixelfont file generation to correctly handle characters wider than
1172      8 pixels.
1173
1174  + Fix expected cross shape so don't always reject using texture mapping to
1175    draw crosses.
1176
[3ea0178]1177  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
1178    as those consisting of just one.  Previously we would trip over the empty
1179    tube later.  Such tubes can for example be created by extend if a splay shot
1180    is the start or end of a tube.
1181
[5b9942e]1182  + Make the green colour used for entrances in the survey tree the same
1183    (slightly darker than before) green used for the entrance blobs.
1184
1185  + Report the version of the library we're actually running with if built
1186    against wx >= 2.9.2.  Make it clear that the version reported is the
1187    version *built* with for wx < 2.9.2.
1188
[3ea0178]1189* extend:
1190
1191  + Copy the end markers for passage tubes.
[5b9942e]1192
[3ea0178]1193  + Preserve left and right data for tubes (previously they were set to -1.0
1194    which means "no info").
1195
1196* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
1197  was no longer used - it certainly is!
1198
1199* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
1200  messages, and curly single right quote instead of straight ASCII apostrophe.
1201  Fall back to using straight ASCII versions if we can't represent them in the
1202  current character set.
[5b9942e]1203
[3ea0178]1204* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]1205
1206* Test suite:
1207
1208  + Add test coverage for interleaved diving data.
1209
1210  + Add testcase for diving data with topofil-style distance.
1211
[94960ad]1212Changes in 1.2.2 (2011-10-06):
1213
1214* aven:
1215
1216  + Replace the textured-mapped font drawing with an approach based on
1217    glBitmap.  This doesn't suffer from the character alignment issues which
1218    the textured-mapped fonts had, and is actually significantly faster on some
1219    machines.  The current font used is (mostly) fixed-width, but this isn't an
1220    inherent limitation - it was just the easiest font data to convert to a
1221    usable format.
1222
1223  + Fix assertion failure due to rounding differences on loading certain .3d
1224    files.  (ticket#26)
1225
1226  + Fix assertion failure when turning on 3D passages if they stick out higher
1227    or lower than any station.  (ticket#29)
1228
[53f8a93]1229  + Fix grid not to disappear when blobs are turned on and blobs are drawn
1230    using lines.
1231
[94960ad]1232  + If a degree sign isn't available in the character set in use, transliterate
1233    it to 'dg' rather than skipping it.
1234
1235  + Fix message which should have been a degree sign but got lost in the format
1236    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
1237    that bearings in the status bar now have a degree sign after them if they
1238    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
1239
1240  + Fix print dialog to calculate the scale required for "One page" right
1241    before it calculates how many pages are required, so we don't end up
1242    something other than 1x1 being shown when the user changes settings.
1243
1244  + Update the calculations for picking a scale and for deciding how many
1245    pages are needed to take into account the change in info box height made
1246    in 1.2.1.
1247
[9704252]1248Changes in 1.2.1 (2011-10-04):
[e3c58c3]1249
1250* Translation updates for US English.
1251
1252* aven:
1253
1254  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
1255    it now shows colours for dates and errors as well as depths.
1256
1257  + In the colour key for "colour by date", change "No info" to "Undated".
1258
1259  + Remove the dark grey background from the colour key and just put a single
1260    pixel black border around the colours.  This is more in keeping with the
1261    other controls, and means the colours are now on a black background so more
1262    visually similar to the survey legs.
1263
1264  + Move the colour key's "Undated"/"Not in loop" entry down a little to
1265    improve the appearance.  Make each section a pixel taller.
1266
[9704252]1267  + Allow "Colour by X" to be selected even if there's no data for X or only a
1268    single value of X used (the colour key is much smaller in these cases, and
1269    does still provide some useful information).
1270
1271  + Fix incorrect calculation of depth colouring for survey legs which straddle
1272    a depth band boundary.
[e3c58c3]1273
1274  + The scale bar, compass, clino, and colour key now all have right click
[9704252]1275    menus which allow related actions to be performed (especially handy in
1276    full-screen mode).
[e3c58c3]1277
1278  + Improve the font used on the survey pane - it now contains the '-'
1279    character (so the clino now shows negative angles as negative, and dates
1280    in the colour key are now hyphenated).  Also the spacing and alignment
1281    are a little better, though still not perfect.
1282
1283  + PLT file export now handles spaces and control characters in station names
1284    by escaping them with '%' as in URLs.
1285
1286  + Pressing "Enter" on a station in the tree control now centres the view on
1287    that station.
1288
1289  + The scale bar is now cached in an OpenGL display list since it often gets
1290    redrawn exactly the same - for example, when rotating, panning, etc.
1291
1292  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1293    then forces a refresh of the survey pane.  This is intended as a debugging
1294    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]1295    where a list should have been invalidated (please report if you find such
1296    a case as it is a bug).
[e3c58c3]1297
[9704252]1298  + We now automatically track which OpenGL display lists need to be
1299    invalidated on window width or height changes.
[e3c58c3]1300
1301  + Increase scale bar maximum width from 65% of the window width to 75% as it
1302    was in 1.0.x (except that if that would overlap the clino we now reduce
1303    that proportion down until it reaches 50%).  Make the limit of zooming in
1304    the same as in 1.0.x.  (ticket#23)
1305
[9704252]1306  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1307    the application was fullscreen (the dialog got opened under the main
1308    window!)  To work around this, aven would switch out of full screen mode
1309    temporarily while showing a dialog.  This case works properly with recent
1310    wxGTK, so disable our workaround with versions we know work.  Also, apply
1311    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1312    as there's no reason to think we need it for other platforms.
[e3c58c3]1313
1314  + Grey out the "View North" action when we're already viewing North, and
1315    similarly for other compass points.
1316
1317  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1318    info in the "About" dialog.
1319
1320  + Fix to set the correct filename on the root of the survey tree - previously
1321    the filename of the previous file loaded was used!
1322
1323  + The movie export code now works with newer versions of the FFmpeg libraries
1324    as well as still working with older versions.
1325
1326  + Fix mixed up messages - the print dialog now says "View" on the left
1327    subgroup of controls rather than some unrelated message.
1328
1329  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1330    field which gives the bearing and reduce the height on the info box by the
1331    removed field, so it's now 3cm for plans and elevations, as for extended
1332    elevations.  Report the tilt angle for tilted elevations which it seems has
1333    been missing for ages (it's not in recent 1.0.x either).
1334
1335  + Tweak the exact positioning of informational text on printouts to look
1336    nicer and make better use of the available space.
1337
1338  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1339    dialog.
1340
1341  + Make the sign of the tilt angle for printouts consistent with the sign
1342    shown by the "clino" in the survey pane.
1343
1344  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1345    and similarly for the "Elevation" button.
1346
[9704252]1347  + (Microsoft Windows version): Sort out appearance of custom cursors.
1348
[e3c58c3]1349  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1350
1351  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1352    you can't get out again easily, so add code to explicitly check for F11
1353    being pressed and toggle full screen.
1354
1355* (Linux version): Fix the RPM .spec file for where man pages now get installed
1356  and package aven.svg and the vim support files.  (Fixes from James Begley)
1357
1358* "make check" now performs several checks on the translation files.
1359
1360* More messages are now available to be translated.
1361
1362* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1363  the message handling changes in 1.2.0.
1364
1365* Fix warning when compiling with GCC.
1366
1367* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1368  sudo for installing on Unix.
1369
1370* In the manual, replace the instructions for building from source with a
1371  pointer to the clearer instructions in INSTALL.
1372
1373* In the manual, make it clear that installing with administrator rights
1374  also applies to newer platforms than XP.
1375
1376* doc/TODO.htm: Update.
1377
[120c1c6]1378Changes in 1.2.0 (2011-09-20):
[b4ac7007]1379
1380* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1381  English.
1382
[9cfcb3f]1383* tests/smoke.tst: aven no longer requires an X display for --help or
1384  --version, so replace skip of this check with a check that this remains the
1385  case.
1386
1387* We now use the standard .po and .pot file formats for storing translations
1388  (rather than the Survex-specific messages.txt format), and then translate
1389  these into Survex's .msg format.
1390
[b4ac7007]1391* (Unix version): Move survex man page to section 7 (since it isn't documenting
1392  an actual command).
1393
[9cfcb3f]1394* (Unix version): Write each generated man page to a temporary file, then
1395  atomically rename, to avoid leaving an empty or partial man page behind if
1396  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1397  recurrence of that).
1398
[b4ac7007]1399* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1400  than /usr/doc/survex.
1401
1402* aven:
1403
[120c1c6]1404  + Fix handling of accented characters in the survey pane.
1405
[9cfcb3f]1406  + Aven icon redrawn in SVG format - it's now a vector image which looks
1407    nicer at larger sizes.
1408
[b4ac7007]1409  + Explicitly request double-buffering, which seems to be needed for systems
1410    with GLX >= 1.3.
1411
1412  + Fix crash while trying to load certain .3d files.
1413
1414  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]1415    Currently this is disabled in Microsoft Windows builds, pending getting the
1416    required libraries set up for building releases.
[b4ac7007]1417
1418  + Reporting of errors during movie export improved.
1419
1420  + Force playback speed to "x1" during movie export.
1421
1422  + Use stock IDs for buttons where appropriate - such buttons may now be
1423    rendered with icons on some platforms.
1424
[9cfcb3f]1425  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1426    ISO8859-1).
1427
1428  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1429    as it's no longer required with modern versions.
1430
1431  + Don't redraw the survey on every mouse movement in the survey pane unless
1432    the measuring line is (or just was) active.  (ticket #17)
1433
[b4ac7007]1434* cavern:
1435
1436  + Drop "non-fatal" from the report of how many errors there were at the end
1437    of the run - it just confuses users - we won't even get here if there's a
1438    fatal error!
1439
[9cfcb3f]1440  + Add --3d-version option to allow the user to specify the version of the 3d
1441    format to output.  (ticket#21)
1442
1443* img library:
1444
1445  + Make the highest and lowest valid values for img_output_version available
1446    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1447
[b4ac7007]1448* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]1449  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]1450
[8f9b0b6d]1451Changes in 1.1.16 (2011-05-16):
[ecdb631]1452
1453* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1454  Portuguese, and US English.
1455
1456* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]1457  rather than '->' where these characters are available.
[ecdb631]1458
1459* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1460  GNU ld --as-needed (Debian bug #615781).
1461
1462* img.c:
1463
1464  + Fix code typo for IMG_API_VERSION == 0 case.
1465
1466  + Fix code typo in code used when IMG_HOSTED isn't defined.
1467
1468* doc/TODO.htm: Remove entries which have now been done.
1469
[8f9b0b6d]1470* (Microsoft Windows version): aven: We now include all the available
1471  translations for messages from wxWidgets, which means that standard widgets
1472  will appear translated where available even if Survex messages aren't
1473  translated.
1474
[f5e3521]1475Changes in 1.1.15 (2010-10-15):
[2d16e4e]1476
1477* aven:
1478
1479  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1480    follow terminology in manual and elsewhere.  Fixes ticket#15.
1481
1482  + When displaying output from cavern, don't update the window after every
1483    line, but only when we don't have data from cavern pending.  Hopefully
1484    addresses ticket#12.
1485
1486  + If we aren't using GL_POINTS for blobs, draw them using a series of
1487    abutting lines rather than with gluDisk which is faster and gives a
1488    consistent shape.
1489
1490  + Check whether blobs and crosses actually render correctly as points/point
1491    sprites, and if they don't, fall back to drawing them with lines.  The
1492    best method is cached on disk, and rechecked automatically if the graphics
1493    hardware is changed or the drivers upgraded.
1494
1495  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1496    though, so we still enable USE_FNT by default).
1497
1498  + Don't offer "All files" wildcard in presentation save dialog.
1499
1500  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1501    more places.
1502
1503  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1504    when running cavern from aven.  Fixes ticket#11.
1505
1506* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1507
1508* diffpos: Handle files with duplicate labels in better - extend generates
1509  duplicate labels when it breaks a loop.
1510
1511* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1512
1513* New v7 of .3d format which stores survey dates as number of days since
1514  January 1st 1900, so we now support dates from 1900-2078 (rather than
1515  1970-2037) with a smaller file size.  The img API is now versioned - you
1516  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1517  gives the survey dates in days in days1 and days2 instead of as time_t
1518  values in date1 and date2.  Fixes ticket#14.
1519
1520* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1521  former has been the canonical name for some time, with www.survex.com just
1522  redirecting to it.
1523
1524* (Unix version): Use unlocked file I/O if available, which can be much faster
1525  in some cases (we don't need the locking as we don't do multithreaded file
1526  I/O).
1527
1528* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1529  headers.
1530
1531* (Mac version): buildmacosx.sh now works again.
1532
1533* Most tests weren't actually running any testcases (looks like a sh
1534  portability issue).  This is now fixed, and fortunately all tests still pass.
1535
1536* Include the extra .isl translation files for Innosetup in the source archive.
1537
[f9473ab]1538Changes in 1.1.14 (2010-07-26):
1539
1540* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1541
1542* aven:
1543
1544  + After processing survey data, if there were warnings or errors, add a
1545    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1546    were only warnings, also add an "OK" button to allow moving on to viewing
1547    the processed survey data (fixes ticket#13).
1548
1549  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1550
1551  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1552    not the ': ' after), and to make the title for the terminal the
1553    warning/error message.  Avoid false positives by checking that '<line>' is
1554    a number.
1555
1556  + Don't double escape the contents of href and target in links in the cavern
1557    log window.
1558
1559  + Improve handling of the splitter window, fixing behavioural glitches in
1560    various cases.
1561
1562  + Highlight stations matching any current search when a file is loaded.
1563    (ticket#9)
1564
1565  + (Mac version): Fix build issue due to Mac OS X polluting the global
1566    namespace with its own "Point" class.
1567
1568  + (Unix version): The Gnome print dialog has its own preview window so
1569    suppress ours if using the Gnome one.
1570
1571  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1572
1573  + (Microsoft Windows version): Fix handling of a double-click on the survey
1574    tree when built with wxWidgets >= 2.8.11.
1575
1576* cavern: Report relevant file and line number for three warnings which didn't
1577  give them before.
1578
1579* (Unix and Mac versions): configure: Update the wx-config probing code -
1580  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1581  point looking for them now.
1582
1583* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1584  for easy installation.  Update it to work with the latest Survex versions
1585  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1586  private wxWidgets, use 2.8.11 not 2.7.0-1).
1587
1588* manual:
1589
1590  + Correctly capitalise "GTK".
1591
1592  + Note that on Linux we only regularly test builds with the GTK+ version
1593    (change taken from 1.0).
1594
1595* Fixed the cad3d man page, which was an empty file in 1.1.13.
1596
[0bd49eb]1597Changes in 1.1.13 (2010-06-16):
[90d0d71]1598
1599* Say "wxWidgets" instead of "wxWindows" consistently.
1600
[739b92c]1601* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1602
1603* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1604
1605* aven:
1606
[90d0d71]1607  + wxWidgets 2.6.0 or newer is now required.
1608
1609  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1610    work but hasn't been tested recently (all packaged versions of wxWidgets
1611    seem to be Unicode now).
1612
1613  + Fix potential uses of uninitialised variables which may have been causing
1614    occasional glitches when loading a file on start-up.
1615
[e4bfd2f]1616  + Improvements to the handling of the font used for plotting labels and other
1617    text on the survey pane:
1618
1619    - Loading the font file is more efficient.
1620
1621    - Character spacing is improved.
1622
1623    - Default font is now anti-aliased.
[90d0d71]1624
1625  + "About" dialog:
1626
1627    - Add "Copy" button to copy the system info to the clipboard for easier
1628      bug reporting.
1629
1630    - List OpenGL extensions last, since there are usually lots of them with a
1631      modern gfx card.
1632
1633    - Fix 100% CPU usage while the "About" dialog is open.
1634
1635  + Processing .svx files:
1636
1637    - Passing a .svx file on the command line now works better.
[1324d6c]1638
[739b92c]1639    - Put the survey data log window in a splitter in the usual frame rather
1640      than opening a separate frame for it.
1641
[90d0d71]1642    - Auto-scroll the log window until we've reported a warning or error.
1643
1644    - Fix small memory leak.
1645
1646  + The presentation filename now defaults to using the basename of the
1647    currently loaded dataset, but we always prompt before we first save with
1648    such a name.
1649
1650  + Reduce memory usage when saving a screenshot.
1651
[e4bfd2f]1652  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1653    persist the window size (and maximised or fullscreen state) between
1654    invocations.
1655
[90d0d71]1656  + Fix reporting of OpenGL errors.
1657
1658  + Fix glitches when tilting while looking East.
1659
[739b92c]1660  + Added Portuguese and Slovak translations of wxWidgets messages.
1661
[90d0d71]1662* Documentation:
1663
[e4bfd2f]1664  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1665
1666  + Drop the "alternative manual formats" self-extracting zip file - people
1667    will generally just want one of the formats, so downloading several
1668    together isn't very useful.
1669
[90d0d71]1670  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1671
1672  + GPL.htm: Replace HTML version of licence with a link to the version on
1673    the FSF website.
1674
1675  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1676    low level to be of interest to non-developers, and developers can look at
1677    the source code.
1678
1679* (Unix version): configure: New preferred name for specifying wx-config script
1680  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1681
[e4bfd2f]1682* (Linux version): Source RPM package dropped as you can just build an RPM
1683  package from the source tarball.
1684
[739b92c]1685* (Microsoft Windows version): The installer is now created with a newer
1686  version of InnoSetup, which gives a 10% smaller download.
1687
[2e12f8c]1688Changes in 1.1.12 (2007-02-07):
[5940815]1689
1690* aven:
1691
[3db0798]1692  + Remember the window size or maximised/fullscreen state between invocations.
1693
[5940815]1694  + Add options dialog to "Export" similar to the one for "Print".
1695
[6b2113d]1696  + The "number of pages required" in the print dialog now updates when you
1697    change what is to be shown (underground legs/surface legs/station
1698    names/crosses).
1699
[920b066]1700Changes in 1.1.11 (2006-11-25):
1701
1702* Updated Czech, Spanish, and Slovak translations.
1703
[99d8798]1704* (MacOS X version): Assorted OS X specific tweaks and fixes.
1705
[920b066]1706* aven:
[78c67a6]1707
[920b066]1708  + Pick a smaller and clearer font for labels.
[99d8798]1709
[920b066]1710  + Fix character spacing.
[99d8798]1711
[920b066]1712  + Tweak display of bearing and elevation angles to look nicer with
1713    proportional fonts.
[99d8798]1714
[920b066]1715  + Use the title from the 3d (or plt, etc) file for the window title
1716    rather than the filename.
[99d8798]1717
[920b066]1718  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1719
[920b066]1720  + Only consider underground legs when calculating the depth bands and
1721    depth colouring.
[99d8798]1722
[920b066]1723  + Add "Colour by Error".
[99d8798]1724
[920b066]1725  + Add entry for "white" in date and error keys.
[99d8798]1726
[920b066]1727  + When setting the view to a single point, don't change the scale.
[99d8798]1728
[920b066]1729  + If reloading the same file, don't change the view
[99d8798]1730
[920b066]1731  + Fix filetypes selector in open dialog.
[99d8798]1732
[920b066]1733  + Fix the charset we use for aven in certain cases.
[99d8798]1734
[920b066]1735  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1736
[920b066]1737  + Pass wx the full language code to initialise the C library locale.
[99d8798]1738
[920b066]1739  + Fix bug in generating prefix tree view which could lead to a bogus
1740    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1741
[920b066]1742  + "New Presentation" now ensures that the side panel is open
[99d8798]1743
[920b066]1744  + Fix updating of cached opengl lists when the view is reset to the
1745    default.
[99d8798]1746
[920b066]1747* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1748  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1749
[920b066]1750* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1751  specified.  Either/both can be set to ":".
[99d8798]1752
[920b066]1753* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1754
[920b066]1755* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1756
[920b066]1757Changes in 1.1.10 (2006-07-14):
[ac3f376]1758
1759* aven: Clicking on a survey name in the survey tree now highlights it in
1760  the map view.  Double-clicking zooms the view to show the clicked survey
1761  highlighted.  Clicking the root clears the highlighting and double-clicking
1762  the root restores the default view.  To expand/collapse a branch, click
1763  on the "[+]" or "[-]" icon to the left of the survey name.
1764
1765* aven: The measuring line can now measure to anywhere in plan or elevation
1766  view (not just to a station!)  In plan view the horizontal distance and
1767  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1768
[ac3f376]1769* aven: Moving the mouse over a station in the survey view now highlights
1770  that station in the survey tree (though it may not be visible if the
1771  survey(s) it is in aren't expanded).
1772
1773* aven: Clicking on a station to centre the view now moves the mouse pointer
1774  to the new location of the station (except on Mac OS X where this isn't
1775  allowed).
1776
1777* aven: Fix which presentation toolbar buttons are shown as depressed.
1778
1779* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1780
1781* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1782
[920b066]1783Changes in 1.1.9 (2006-07-04):
[6a2594be]1784
1785* (Unix version): Install desktop files for aven and svxedit contributed to the
1786  Ubuntu package by Phil Bull, and corresponding pixmaps.
1787
1788* Fix img to filter out cross-sections which don't match the subsurvey (if
1789  specified).  The API now returns img_XSECT_END to mark the end of a
1790  passage rather than setting a flag on the last img_XSECT of the passage.
1791
1792* Enhance integration with the vim editor - this can now colour .err files, run
1793  cavern from vim and parse error output, and run aven from vim.  Tweak the
1794  existing vim mode for .svx files to fix a few minor bugs and add support for
1795  the new "*data passage" style.
1796
1797* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1798  which can't draw large enough blobs for us.
1799
1800* aven: sort out confusion about what encoding everything is in which means
1801  that the distance measured by the measuring line actually gets displayed
1802  and also fixes problems with empty menu items in non-English locales in
1803  some cases.
1804
1805* aven: redraw grey background after a menu is closed over the aven window
1806  with no survey loaded.
1807
1808* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1809
1810* aven: avoid crash on some machines when opening "About" dialog before having
1811  loaded a survey.
1812
1813* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1814
1815* (Unix version): aven: Fix character set handling of cavern output.
1816
1817* cavern: Report an error if a cross-section is specified for a station which
1818  doesn't exist.
1819
1820* Updated French and Italian translations.
1821
1822* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1823  `${prefix}/share/survex'" error.
1824
[6a2594be]1825* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1826  (doesn't affect Survex itself, but other applications which use img.c should
1827  update their copy).
1828
1829* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1830  and later are caught by configure, whereas older wx versions are caught when
1831  trying to compile).
1832
[920b066]1833Changes in 1.1.8 (2006.06.30):
[cd39f67]1834
[c988ae4]1835* Drop support for building with wxWidgets versions prior to 2.4.0
1836  (which was released on 2003-01-07).
1837
[9577fcc]1838* aven: Printing through aven now uses settings from the "[aven]" section
1839  of print.ini, and support for hierarchical sections (using "like=")
1840  has been disabled.
1841
[ecf2d23]1842* aven: Change mouse actions to be compatible with those in Survex 1.0.
1843  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1844  left drag is now smart about not rotating and zooming at the same
1845  time.
1846
[d1628e8e]1847* aven: Highlighting stations now happens as you type, and pressing
1848  "Enter" or clicking the "Find" button now pans and zooms to show the
1849  highlighted stations.
1850
[e67ed1b]1851* aven: Left-clicking away from a station now cancels measuring line.
1852
[3ddd351]1853* aven: Setting view to North, South, East, or West is now animated like
1854  the tilt from plan to elevation.
1855
[c988ae4]1856* aven: Fix presentation saving to also write "." for decimal points and
1857  presentation loading to accept either "." or ",".
1858
1859* (Unix version): aven: Add text for all toolbar items so that aven
1860  will work with the Gnome desktop preference for displaying toolbars as
1861  icons with text or just text (wxWidgets needs fixing first though).
1862
1863* (Unix version): aven: Remove the ability to detach the menu bar (yell
1864  if you actually used it and I'll restore it!)
1865
1866* aven: Add "all survey files" option to the "open file" dialog.
1867
[84f1ed1]1868* (MS Windows version): aven: Fix cursor keys to pan survey.
1869
[a884696]1870* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1871
[9fe7af4f]1872* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1873  run by an unprivileged user.
1874
1875* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1876  installer builder we use) and include new installer translations for
1877  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1878
1879* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1880  translations of messages for wxWidgets (the GUI library we use).
1881
[cd39f67]1882* aven: Disable "Highlight exported points" if there aren't any.
1883
[afffec4]1884* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1885  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1886
[38a192d]1887* (Unix version): test suite: fix smoke test to pass even without X running
1888  (it was meant to but the code had a bug).
1889
[5892e08]1890* aven: Check if OpenGL is available and exit cleanly with a helpful error
1891  if it isn't.
1892
[879e9c3]1893* (Unix version): aven: Fix --help and --version to work without a working
1894  X display (provided it's built with wxWidgets 2.5.1 or newer).
1895
[c8f929b]1896* aven: Automatically select the presentation tab of the notebook when the user
1897  selects "New Presentation" or "Open Presentation".
1898
1899* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1900  reset to default view as well).
1901
1902* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1903  empty.
1904
1905* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1906  up and down instead of being passed on and moving the survey.
1907
[9ad92cc]1908* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1909  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1910  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1911
1912* aven: Put a 5mm border around exported SVG files to allow for station markers
1913  and non-zero width lines.
1914
1915* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1916  was turned on.
1917
1918* aven: Actually close the file we're exporting which fixes problems with it
1919  not always being fully written.
1920
[920b066]1921Changes in 1.1.7 (2005.10.18):
[6662d02]1922
1923* cavern: Add validity checking for dates in *date commands (with feature
1924  test in testsuite).  A date entered as just "year" or "year.month" now
1925  becomes a date range for the relevant period (previously it became a single
1926  date near the middle of that period).
[e0c7cd1]1927
[8add4c9]1928* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1929  with MS Windows).
1930
[9f524ee]1931* extend: Default output name for a file called input.3d is now input_extend.3d
1932  rather than just extend.3d (which was annoying if you wanted to extend
1933  several surveys in the same directory).
1934
[185d793]1935* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1936  our check for them to include that knowledge.
[185d793]1937
[3515947]1938* aven: Regenerate depth bar if user switches to/from metric units.
1939
[1235f9b]1940* aven: Don't clear the "there" mark just because the mouse pointer has
1941  moved off a station.
1942
[4299674]1943* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1944  same directory (since that's where we then try to load it from).
[4299674]1945
[60dbe70]1946* aven: Fix labelling of date colouring on 32 bit platforms.
1947
[125c9ea]1948* aven: If "colour by date" is on and we load a survey with no date info
1949  (or all surveyed on the same date) then set "colour by none".
1950
[ec58e3d3]1951* aven: Make the error dialog modal and remove a signal handler once it
1952  has fired to prevent endless (or seemingly endless) cascades of error
1953  dialogs.
1954
[8add4c9]1955* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1956  if a survey file with only one station in is loaded.
1957
[6662d02]1958* aven: Fix problems with indicators disappearing when we're drawing
1959  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]1960  introduced in 1.1.6).
[6662d02]1961
[b65c13f]1962* (Unix version): aven: Really stop setting extra toolbar margin when using
1963  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1964  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1965
[17cce5f]1966* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1967  we've been compiled with, and which GTK+/Motif version where appropriate.
1968
[affaeee]1969* (Unix version): Fixed build on Fedora Core 3.
1970
[618b01f]1971* documentation: Updates to 3d file format specification from Mike McCombe.
1972
[920b066]1973Changes in 1.1.6 (2005.10.10):
[7e01c87]1974
1975* (MS Windows version): Distribution is about a third smaller than 1.1.5
1976  (mostly because mingwm10.dll is no longer required).
1977
[b88b171]1978* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1979  it, showing cavern's output in a window (with errors and warnings clickable
1980  to load the offending file into an editor), and then loading the resulting
1981  3d file.
1982
[7e01c87]1983* aven: Added "Colour by Date" option.
1984
1985* aven: Disable "Colour by Depth" option if there's no elevation variation.
1986
1987* aven: Don't crash if trying to load a survey with no elevation variation.
1988  Instead turn off depth colouring.
1989
[8ea82aa]1990* aven: Export as HPGL added.
1991
[887c26e]1992* aven: Improved update of mouse coordinates and measuring line (thanks to
1993  Martin Green).
1994
[7c29c976]1995* aven: Show the coordinates of either the mouse pointer or the nearest
1996  survey station to it (if there is one near enough).  Showing both was
1997  confusing and meant the status bar overflowed on smaller displays.
1998
[7e01c87]1999* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]2000
[7e01c87]2001* aven: Don't lock "flat" surveys which aren't extended elevations - a
2002  flat survey with LRUD data isn't flat any more!
2003
2004* aven: When we have to draw blobs and crosses the slow way (because the
2005  graphics hardware doesn't support the fast way), draw them so that they
2006  should appear at the correct depth into the 3D scene instead of on top
2007  of everything else.
2008
2009* aven: Make "play presentation backwards" icon green to match the other
2010  presentation icons.
2011
2012* (MS Windows version): aven: Mouse clicks on the survey view now set the
2013  keyboard focus there.
[bd21214]2014
[b46bf92]2015* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
2016
[796d7bf]2017* (MS Windows version): aven: Fix redrawing of measuring line.
2018
[7e01c87]2019* cavern: Store dates for img_XSECT.
2020
2021* cavern: Fixed small one-off memory leak if you specify -o more than once.
2022
[b88b171]2023* (Unix version): Check environmental variable LC_MESSAGES when deciding what
2024  language to use for messages.
2025
[7c29c976]2026* (MS Windows version): "Print" on a 3d file now prints through aven rather
2027  than the separate printer driver (Unix has done this for some time).
2028
[8ea82aa]2029* Removed old printer drivers.
2030
[7e01c87]2031* img library: When creating a 3d file, ignore img_XSECT if we've been asked
2032  to write a file format version which doesn't support it.
[8ea82aa]2033
[920b066]2034Changes in 1.1.5 (2005.09.20):
[106cfdf]2035
2036* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
2037
[4ba80e0]2038* aven: Make blobs round like they are in Survex 1.0.
2039
2040* aven: If the graphics drivers don't support drawing blobs using OpenGL
2041  point markers, fall back to drawing filled circles.
2042
[95ce35f]2043* aven: If the graphics drivers support it, draw crosses as texture mapped
2044  OpenGL point markers which is much faster.
[90d0d71]2045
[95ce35f]2046* aven: Cross size increased to match Survex 1.0.
2047
[cd78148]2048* aven: We must update which blobs are displayed if display of surface or
2049  underground legs is toggled.
2050
[f5627353]2051* cavern: Fix handling of a *solve followed by survey data, none of which is
2052  attached to the previous data.
2053
[dfe4a520]2054* cavern: Fixed "No survey data" error when a *solve is followed by another
2055  *solve (or the implicit solve at the end of processing) with no data between
2056  them.
2057
[920b066]2058Changes in 1.1.4 (2005.09.19):
[4855072]2059
2060* aven: Added Aven's icon to the "About" dialog.
2061
2062* aven: Use localised character for the decimal point (e.g. "," in most
2063  continental European countries).
2064
2065* aven: Previously the survey tree would get focus and then take keypresses
2066  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
2067  operate on the cave, and transfer the input focus across when we do.
2068
2069* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
2070
2071* aven: Speed up intialisation by delaying creation of OpenGL lists until
2072  they're needed.
2073
2074* aven: Added Mark Shinwell's bounding box with shadow of the survey.
2075
2076* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
2077
2078* aven: Reworded "Restore Default Settings" as "Restore Default View".
2079
2080* (Unix version): aven: Set sensible default margins for printing and preserve
2081  any margin values the user specifies between runs (previously margins
2082  defaulted to 0 each time aven was run).
2083
2084* Documentation: Document *DATA PASSAGE in the manual.
2085
[920b066]2086Changes in 1.1.3 (2005.09.07):
[0e558e5]2087
2088* (Microsoft Windows version): Fixed build problems.
2089
2090* cavern: Allow OMIT character (-) for left/right/up/down.
2091
2092* aven: Remove an unnecessary menu separator.
2093
2094* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
2095
2096* aven: Make the tooltip for "Hide" show the number of found stations.
2097
2098* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
2099
2100* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
2101  when there's a presentation loaded.
2102
2103* aven: Make entrances green in side panel tree list to match green blobs used
2104  in cave view.
2105
2106* aven: Don't show surface labels if we're not showing surface data, etc.
2107
2108* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
2109  make "Space" the key for this.  Keep Return working "Stop Rotation" so
2110  existing users are happy, but don't advertise it.
2111
2112* aven: Normalise filename by adding any extension used, and use the normalised
2113  filename for file history and window title.
2114
2115* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
2116  as the toolbar buttons already have a sensible margin - the extra margin is
2117  only needed with GTK1.2.
2118
2119* aven: Fix handling of plumb legs in tube model.
2120
2121* aven: Fixed swapped L and R in tube model.
2122
2123* extend: Preserve UD cross-section information in extended elevation.
2124
2125* extend: Add new messages for John Pybus' enhancements.
2126
2127Changes in 1.1.2 (never formally released):
[8faa5d8]2128
2129* Added support for LRUD data in .svx files, in .3d files, and aven can
2130  now load and display it on screen and on printouts.  The ability to "fake"
2131  LRUD data in aven is gone for now but will reappear in some form later.
2132
2133* cavern: Removed support for writing Chasm's 3dx format.  We're going to
2134  fold any desirable missing chasm functionality into aven.
2135
2136* aven: Rearranged mouse actions as discussed on the mailing list.  Added
2137  cursors for each different mouse action to help the user learn what each
2138  does.  Also added cursors for the "compass" and "clino" as well as the
2139  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]2140
[0e558e5]2141* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]2142
2143* tests/smoketest.tst: If X windows is running, check that we can run aven
2144  with --help and --version.
2145
2146* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
2147  no results are listed for it.  This revealed that there was a "newline" test
[6225339]2148  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]2149  Fixed all these problems.
2150
2151* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
2152  and omitted forward compass/clino readings in Compass DAT files.  Added
2153  a feature test for this to the testsuite.
2154
2155* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]2156  without OpenGL so remove old machinery for this from configure and the
2157  sources.
[8faa5d8]2158
[0e558e5]2159* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]2160
2161* configure: Better output for strcasecmp test.
2162
2163* aven: Fix crosses to work much better.  Not a total fix - their position
2164  in the Z buffer isn't correct and they're rather slow to plot.
2165
2166* aven: Don't regenerate the hittest grid every time the mouse moves while
2167  animating, which solves the mysterious pausing effect (thanks go to Martin
2168  Green for spotting this!)  Also clear all the status bar coordinates when
2169  animating.
2170
2171* aven: Sort out clashing menu shortcuts in some languages.
2172
2173* aven: Fixed compilation problem on x86_64
2174
2175* SPUD: Pruned out stuff which has been done or which is not actually relevant
2176  to this branch.
2177
2178* Merge various changes from 1.0 branch:
2179
2180  + aven: Port over "printing from aven" functionality.
2181
2182  + aven: Port over "export as" functionality,
2183
2184  + Add David Loeffler's vim mode for .svx files.
2185
2186* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]2187
[8faa5d8]2188* aven: Don't use an opengl list for drawing the indicators - we typically make
2189  a new list each time we plot them anyway.
2190
2191* Remove lingering traces of support for RISC OS and pre-386 MSDOS
2192
2193* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]2194  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]2195
2196* configure: Update wxWindows checks to handle newer wx versions.
2197
2198* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
2199  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
2200  for anyone building from CVS).
2201
2202* acinclude.m4: Quote macro name for fix autotools warning.
2203
[4855072]2204* Documentation: "tilt up" is "'" not ",".
[8faa5d8]2205
2206* aven: Add support for mousewheels (to tilt the cave).
2207
2208* aven: Fixed twisted transitions to and from pitches in certain cases.
2209
[0e558e5]2210* aven: Pick a sensible initial window size when the user's desktop is spread
2211  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]2212  better with wx2.4 or earlier as well).
2213
2214* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
2215  contents being visible before any survey is loaded.
2216
2217* aven: Allow a coloured texture to be used
2218
2219* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]2220  is default colour (grey for most systems) not black until a survey is
2221  loaded).
[8faa5d8]2222
2223* aven: Fixed weird "shadowed" icons.
2224
[920b066]2225Changes in 1.1.1 (2004-10-06):
[a7aa27d9]2226
2227* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]2228  startup.
[a7aa27d9]2229
2230* aven: Delay loading the bitmap for the "About" dialog until it is first
2231  needed.  We want start up to be as quick as possible.
2232
[920b066]2233Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]2234
[91e416e]2235* NOTE: Survex 1.1.X releases are development snapshots made available for
2236  the purposes of allowing wider testing and getting more user feedback.  Once
2237  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]2238
[91e416e]2239* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
2240  you're using Windows 95 - these can be obtained from:
2241  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]2242
[91e416e]2243* aven: Solid passages - passage dimensions are currently inferred from
2244  the leg length (pretty effective as you can measure longer legs in
2245  larger passages).  Use of real LRUD data coming soon...
[edb6576]2246
[91e416e]2247* aven: Depth colouring is now continuously varying.
[edb6576]2248
[0580c6a]2249* aven: Colour by depth can now be turned off (and there's the start of a
2250  framework for properly implementing colour by date, error, etc).
2251
[4261983]2252* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
2253  match (? matches any character, * matches any number of characters).
2254
2255* aven: We now use the status bar for coordinates, distances, etc to make
2256  better use of screen space.
[edb6576]2257
[f80077a]2258* aven: Full screen mode (F11).
[edb6576]2259
[6abab84]2260* aven: Perspective view.
2261
[91e416e]2262* aven: Context sensitive cursor shape - needs more work.
