[cd39f67]1TOBE Changes in 1.1.8:
2
[84f1ed1]3* (MS Windows version): aven: Fix cursor keys to pan survey.
4
[9fe7af4f]5* (MS Windows version): Fix installer to work on Windows 2000 or XP if
6  run by an unprivileged user.
7
8* (MS Windows version): Upgrade to the latest version of InnoSetup (the
9  installer builder we use) and include new installer translations for
10  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
11
12* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
13  translations of messages for wxWidgets (the GUI library we use).
14
[cd39f67]15* aven: Disable "Highlight exported points" if there aren't any.
16
[afffec4]17* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]18  Italian, Catalan, Spanish, and Romanian translations.
[581624b]19
[38a192d]20* (Unix version): test suite: fix smoke test to pass even without X running
21  (it was meant to but the code had a bug).
22
[5892e08]23* aven: Check if OpenGL is available and exit cleanly with a helpful error
24  if it isn't.
25
[879e9c3]26* (Unix version): aven: Fix --help and --version to work without a working
27  X display (provided it's built with wxWidgets 2.5.1 or newer).
28
[c8f929b]29* aven: Automatically select the presentation tab of the notebook when the user
30  selects "New Presentation" or "Open Presentation".
31
32* aven: Fix "Delete" in the presentation list to not get passed on (and so not
33  reset to default view as well).
34
35* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
36  empty.
37
38* aven: Fix Cursor Up and Down in the presentation list to move the highlight
39  up and down instead of being passed on and moving the survey.
40
[6662d02]41Changes in 1.1.7:
42
43* cavern: Add validity checking for dates in *date commands (with feature
44  test in testsuite).  A date entered as just "year" or "year.month" now
45  becomes a date range for the relevant period (previously it became a single
46  date near the middle of that period).
[e0c7cd1]47
[8add4c9]48* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
49  with MS Windows).
50
[9f524ee]51* extend: Default output name for a file called input.3d is now input_extend.3d
52  rather than just extend.3d (which was annoying if you wanted to extend
53  several surveys in the same directory).
54
[185d793]55* aven: OpenGL 2.0 always includes support for point sprites so rework
56  our for them to include that knowledge.
57
[3515947]58* aven: Regenerate depth bar if user switches to/from metric units.
59
[1235f9b]60* aven: Don't clear the "there" mark just because the mouse pointer has
61  moved off a station.
62
[4299674]63* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]64  same directory (since that's where we then try to load it from).
[4299674]65
[60dbe70]66* aven: Fix labelling of date colouring on 32 bit platforms.
67
[125c9ea]68* aven: If "colour by date" is on and we load a survey with no date info
69  (or all surveyed on the same date) then set "colour by none".
70
[ec58e3d3]71* aven: Make the error dialog modal and remove a signal handler once it
72  has fired to prevent endless (or seemingly endless) cascades of error
73  dialogs.
74
[8add4c9]75* aven: Enforce a minimum object volume diameter of 1m to avoid problems
76  if a survey file with only one station in is loaded.
77
[6662d02]78* aven: Fix problems with indicators disappearing when we're drawing
79  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]80  introduced in 1.1.6).
[6662d02]81
[b65c13f]82* (Unix version): aven: Really stop setting extra toolbar margin when using
83  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
84  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
85
[17cce5f]86* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
87  we've been compiled with, and which GTK+/Motif version where appropriate.
88
[affaeee]89* (Unix version): Fixed build on Fedora Core 3.
90
[618b01f]91* documentation: Updates to 3d file format specification from Mike McCombe.
92
[7e01c87]93Changes in 1.1.6:
94
95* (MS Windows version): Distribution is about a third smaller than 1.1.5
96  (mostly because mingwm10.dll is no longer required).
97
[b88b171]98* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
99  it, showing cavern's output in a window (with errors and warnings clickable
100  to load the offending file into an editor), and then loading the resulting
101  3d file.
102
[7e01c87]103* aven: Added "Colour by Date" option.
104
105* aven: Disable "Colour by Depth" option if there's no elevation variation.
106
107* aven: Don't crash if trying to load a survey with no elevation variation.
108  Instead turn off depth colouring.
109
[8ea82aa]110* aven: Export as HPGL added.
111
[887c26e]112* aven: Improved update of mouse coordinates and measuring line (thanks to
113  Martin Green).
114
[7c29c976]115* aven: Show the coordinates of either the mouse pointer or the nearest
116  survey station to it (if there is one near enough).  Showing both was
117  confusing and meant the status bar overflowed on smaller displays.
118
[7e01c87]119* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]120
[7e01c87]121* aven: Don't lock "flat" surveys which aren't extended elevations - a
122  flat survey with LRUD data isn't flat any more!
123
124* aven: When we have to draw blobs and crosses the slow way (because the
125  graphics hardware doesn't support the fast way), draw them so that they
126  should appear at the correct depth into the 3D scene instead of on top
127  of everything else.
128
129* aven: Make "play presentation backwards" icon green to match the other
130  presentation icons.
131
132* (MS Windows version): aven: Mouse clicks on the survey view now set the
133  keyboard focus there.
[bd21214]134
[b46bf92]135* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
136
[796d7bf]137* (MS Windows version): aven: Fix redrawing of measuring line.
138
[7e01c87]139* cavern: Store dates for img_XSECT.
140
141* cavern: Fixed small one-off memory leak if you specify -o more than once.
142
[b88b171]143* (Unix version): Check environmental variable LC_MESSAGES when deciding what
144  language to use for messages.
145
[7c29c976]146* (MS Windows version): "Print" on a 3d file now prints through aven rather
147  than the separate printer driver (Unix has done this for some time).
148
[8ea82aa]149* Removed old printer drivers.
150
[7e01c87]151* img library: When creating a 3d file, ignore img_XSECT if we've been asked
152  to write a file format version which doesn't support it.
[8ea82aa]153
[106cfdf]154Changes in 1.1.5:
155
156* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
157
[4ba80e0]158* aven: Make blobs round like they are in Survex 1.0.
159
160* aven: If the graphics drivers don't support drawing blobs using OpenGL
161  point markers, fall back to drawing filled circles.
162
[95ce35f]163* aven: If the graphics drivers support it, draw crosses as texture mapped
164  OpenGL point markers which is much faster.
165 
166* aven: Cross size increased to match Survex 1.0.
167
[cd78148]168* aven: We must update which blobs are displayed if display of surface or
169  underground legs is toggled.
170
[f5627353]171* cavern: Fix handling of a *solve followed by survey data, none of which is
172  attached to the previous data.
173
[dfe4a520]174* cavern: Fixed "No survey data" error when a *solve is followed by another
175  *solve (or the implicit solve at the end of processing) with no data between
176  them.
177
[4855072]178Changes in 1.1.4:
179
180* aven: Added Aven's icon to the "About" dialog.
181
182* aven: Use localised character for the decimal point (e.g. "," in most
183  continental European countries).
184
185* aven: Previously the survey tree would get focus and then take keypresses
186  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
187  operate on the cave, and transfer the input focus across when we do.
188
189* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
190
191* aven: Speed up intialisation by delaying creation of OpenGL lists until
192  they're needed.
193
194* aven: Added Mark Shinwell's bounding box with shadow of the survey.
195
196* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
197
198* aven: Reworded "Restore Default Settings" as "Restore Default View".
199
200* (Unix version): aven: Set sensible default margins for printing and preserve
201  any margin values the user specifies between runs (previously margins
202  defaulted to 0 each time aven was run).
203
204* Documentation: Document *DATA PASSAGE in the manual.
205
[0e558e5]206Changes in 1.1.3:
207
208* (Microsoft Windows version): Fixed build problems.
209
210* cavern: Allow OMIT character (-) for left/right/up/down.
211
212* aven: Remove an unnecessary menu separator.
213
214* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
215
216* aven: Make the tooltip for "Hide" show the number of found stations.
217
218* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
219
220* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
221  when there's a presentation loaded.
222
223* aven: Make entrances green in side panel tree list to match green blobs used
224  in cave view.
225
226* aven: Don't show surface labels if we're not showing surface data, etc.
227
228* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
229  make "Space" the key for this.  Keep Return working "Stop Rotation" so
230  existing users are happy, but don't advertise it.
231
232* aven: Normalise filename by adding any extension used, and use the normalised
233  filename for file history and window title.
234
235* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
236  as the toolbar buttons already have a sensible margin - the extra margin is
237  only needed with GTK1.2.
238
239* aven: Fix handling of plumb legs in tube model.
240
241* aven: Fixed swapped L and R in tube model.
242
243* extend: Preserve UD cross-section information in extended elevation.
244
245* extend: Add new messages for John Pybus' enhancements.
246
247Changes in 1.1.2 (never formally released):
[8faa5d8]248
249* Added support for LRUD data in .svx files, in .3d files, and aven can
250  now load and display it on screen and on printouts.  The ability to "fake"
251  LRUD data in aven is gone for now but will reappear in some form later.
252
253* cavern: Removed support for writing Chasm's 3dx format.  We're going to
254  fold any desirable missing chasm functionality into aven.
255
256* aven: Rearranged mouse actions as discussed on the mailing list.  Added
257  cursors for each different mouse action to help the user learn what each
258  does.  Also added cursors for the "compass" and "clino" as well as the
259  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]260
[0e558e5]261* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]262
263* tests/smoketest.tst: If X windows is running, check that we can run aven
264  with --help and --version.
265
266* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
267  no results are listed for it.  This revealed that there was a "newline" test
[6225339]268  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]269  Fixed all these problems.
270
271* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
272  and omitted forward compass/clino readings in Compass DAT files.  Added
273  a feature test for this to the testsuite.
274
275* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]276  without OpenGL so remove old machinery for this from configure and the
277  sources.
[8faa5d8]278
[0e558e5]279* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]280
281* configure: Better output for strcasecmp test.
282
283* aven: Fix crosses to work much better.  Not a total fix - their position
284  in the Z buffer isn't correct and they're rather slow to plot.
285
286* aven: Don't regenerate the hittest grid every time the mouse moves while
287  animating, which solves the mysterious pausing effect (thanks go to Martin
288  Green for spotting this!)  Also clear all the status bar coordinates when
289  animating.
290
291* aven: Sort out clashing menu shortcuts in some languages.
292
293* aven: Fixed compilation problem on x86_64
294
295* SPUD: Pruned out stuff which has been done or which is not actually relevant
296  to this branch.
297
298* Merge various changes from 1.0 branch:
299
300  + aven: Port over "printing from aven" functionality.
301
302  + aven: Port over "export as" functionality,
303
304  + Add David Loeffler's vim mode for .svx files.
305
306* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]307
[8faa5d8]308* aven: Don't use an opengl list for drawing the indicators - we typically make
309  a new list each time we plot them anyway.
310
311* Remove lingering traces of support for RISC OS and pre-386 MSDOS
312
313* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]314  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]315
316* configure: Update wxWindows checks to handle newer wx versions.
317
318* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
319  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
320  for anyone building from CVS).
321
322* acinclude.m4: Quote macro name for fix autotools warning.
323
[4855072]324* Documentation: "tilt up" is "'" not ",".
[8faa5d8]325
326* aven: Add support for mousewheels (to tilt the cave).
327
328* aven: Fixed twisted transitions to and from pitches in certain cases.
329
[0e558e5]330* aven: Pick a sensible initial window size when the user's desktop is spread
331  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]332  better with wx2.4 or earlier as well).
333
334* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
335  contents being visible before any survey is loaded.
336
337* aven: Allow a coloured texture to be used
338
339* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]340  is default colour (grey for most systems) not black until a survey is
341  loaded).
[8faa5d8]342
343* aven: Fixed weird "shadowed" icons.
344
[a7aa27d9]345Changes in 1.1.1:
346
347* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]348  startup.
[a7aa27d9]349
350* aven: Delay loading the bitmap for the "About" dialog until it is first
351  needed.  We want start up to be as quick as possible.
352
[0580c6a]353Changes between 1.0.32 and 1.1.0:
[edb6576]354
[91e416e]355* NOTE: Survex 1.1.X releases are development snapshots made available for
356  the purposes of allowing wider testing and getting more user feedback.  Once
357  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]358
[91e416e]359* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
360  you're using Windows 95 - these can be obtained from:
361  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]362
[91e416e]363* aven: Solid passages - passage dimensions are currently inferred from
364  the leg length (pretty effective as you can measure longer legs in
365  larger passages).  Use of real LRUD data coming soon...
[edb6576]366
[91e416e]367* aven: Depth colouring is now continuously varying.
[edb6576]368
[0580c6a]369* aven: Colour by depth can now be turned off (and there's the start of a
370  framework for properly implementing colour by date, error, etc).
371
[4261983]372* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
373  match (? matches any character, * matches any number of characters).
374
375* aven: We now use the status bar for coordinates, distances, etc to make
376  better use of screen space.
[edb6576]377
[f80077a]378* aven: Full screen mode (F11).
[edb6576]379
[6abab84]380* aven: Perspective view.
381
[91e416e]382* aven: Context sensitive cursor shape - needs more work.
[edb6576]383
[91e416e]384* aven: Mouse actions changed (hopefully they're now more natural, but
385  you may find the change disorientating - feedback wanted on this).
[edb6576]386
[1690fa9]387* aven: Added "presentations" which allow you to set up fly-through paths
388  and load/save/run them.
389
[0580c6a]390* aven: A presentation can be exported as a movie file.
391
[045e2af]392* aven: Added Save screenshot facility.
393
[c60062d]394* aven: Depth fogging option.
395
[0580c6a]396* aven: Added Smooth Lines option.
397
398* aven: Added Textured Walls option.
399
[f433fda]400* aven: If a survey has surface legs but no underground legs, default to
401  showing the surface legs.
402
[0580c6a]403* cavern: Dates given to *date are now stored in the 3d file.
[da6c802]404
[0580c6a]405Changes in 1.0.32:
[db452ae]406
[0580c6a]407* aven: Fixed font sizes in "Print Preview" and printouts.
[a517825]408
[0580c6a]409* aven: In the print setup dialog, replaced "Orientation" radio buttons with
410  "Plan" and "Elevation" buttons.
411
412* aven: Fixed info box on printouts of elevations, tilted views, and
413  extend elevations.
414
415* aven: Added "fit on one page" option, and make it the default.
416
417* aven: Reorder "Cancel", "Preview", "Print" buttons and make "Print" the
418  default button.
419
420* aven: Read settings back from the print dialog when the "Print" button is
421  pressed (was only done for "Preview" previously).
422
423* aven: Sorted out the initial size of the "Print Preview" window.
424
425* aven: Fixed the window manager's close button on the "Print Preview" window
426  - previously this was being ignored.
427
428* aven: Sorted out initial survey scaling when loading a survey at startup.
429
430* aven: Fixed the measuring line to work better when the survey tree is
431  manipulated with keys.  Tweaked redrawing of the measuring line to be a
432  smidgen more efficient.  Fixed the blob and ring size which were one
433  pixel too small on Windows.
434
435* aven: Added "System Information:" section to the "About" dialog to hold
436  information useful when reporting bugs.  Currently it contains the wxWindows
437  version, OS version, and colour depth information.
438
439* aven: Changed the "About" dialog's "Close" button to be "OK" for consistency
440  with pretty much every other application.
441
442* aven: Added "File->Export as..." which integrates cad3d's functionality
443  within aven.
444
445* aven: Updated a few icons.
446
447* cad3d: Added SVG export support from John Pybus
448
449* (Unix version): Fixed to allow compilation with GCC 3.4
450
451* (MS Windows version): Upgrade to using innosetup 4 for the installer
452  (we were using innosetup 2).  This results in a much smaller download
453  and the installer now translates itself into the currently set language.
454  The installer will no longer work on Windows NT 3.51, but I seriously
455  doubt anyone is still using that...
456
457* Updates to German translation.
458
459Changes in 1.0.31:
460
461* (MS Windows version): Fixed problems with the new printing code by building
462  with a newer version of wxWindows (2.5.2 instead of 2.4.1).
463
464* aven: Fixed grid menu item so that it always correctly reflects whether the
465  grid is enabled or not.
466
467* aven: Minor improvements to appearance of a few toolbar icons.
468
469* Updates to Catalan, French, Italian, Romanian, Slovak, and Spanish
470  translations.
471
472* cavern: Fixed Romanian message which was appearing in English .err files.
473
474Changes in 1.0.30:
475
476* aven: Added printing directly from Aven!
477
478* aven: Fixed memory leak when showing the "About" dialog.
479
480* (MacOS X version): Now installable from a disk image package.
481
482* cavern: Equates are no longer considered when deciding which stations are
483  flagged as surface and underground.
484
485* Romanian translation mostly completed.
486
487* (Unix version): Debian: Minor packaging tweaks.
488
489Changes in 1.0.29:
490
491* cad3d: Fixed problem with DXF files which stopped them loading with some
492  drawing packages (introduced in 1.0.27).
493
494* aven: Changed File->Exit to File->Quit.
495
496* Removed some unused messages from the message files.
497
498* (Unix version): Fixed SRPMs to build on RedHat 9 and Fedora Core 1 (patch
499  from John Pybus).
500
501* Romanian translation started.
502
503* (Unix version): Debian: Fixed new lintian warnings about missing quotes in
504  menu files.
505
506Changes in 1.0.28:
507
508* Fixed 3d file reading code to fix incorrect unpacking of compressed station
509  names in a rare case.  Also checked other rare cases work correctly.
510
511Changes in 1.0.27:
512
513* cad3d: DXF output now puts surface legs, stations, and labels in separate
514  layers.
515
516* (Unix version): distribute desc-svxedit.txt.
[b462168]517
[1809849]518Changes in 1.0.26:
[b462168]519
[b4fe9fb]520* cavern: Fixed interleaved topofil data style - the length was always being
521  calculated as zero.
[b462168]522
523* (Unix version): aven: "All Files" now shows files without extensions too.
524
[b4fe9fb]525* aven: added Ctrl+Q as shortcut for File->Exit.
526
527* aven: depth colouring now uses a proper colour gradient.
528
529* (MacOS X version): aven: the keyboard and mouse now work!  It turns out that
530  we must apply resources *after* installing.
531
532* (MacOS X version): aven: now works when run from the MacOS X Finder.
533
534* (MacOS X version): look for message files and other resources relative to the
535  binaries so that the user can install Survex from a disk image in the location
536  of their choice.
537
538* (MacOS X version): fixed not to try to build aven if wxWindows isn't
539  installed.
540
[63dc4eb]541* cad3d: fixed -e and -r options to not crash (the long versions have always
542  worked).
543
544* extend: fixed to initialise an internal structure - failing to do so was
545  probably causing crashes on some platforms.
[b4fe9fb]546
[2934e83]547* Fixed standard graphics for "Note", "Warning", etc in the PostScript manual.
548
[b4fe9fb]549* Documentation updated.
550
[63dc4eb]551* (Unix version): fixed svxedit man page which previously contained xcaverot
[b4fe9fb]552  documentation!
553
554* test suite: check that cavern doesn't report "nan" or "NaN" for any values.
555
[63dc4eb]556* (Unix version): fixed configure --enable-defaultlang=XX to work.
[b4fe9fb]557
558* (Unix version): fixed configure code to turn on lots of GCC warnings and fixed
559  most of them.
[b5a3219]560
[63dc4eb]561* (MS Windows version): assorted tweaks to allow building with MS Visual C/C++.
562
[b462168]563Changes in 1.0.25:
564
565* (MacOS X version): hopefully fixed building of aven.
566
567* (Unix version): updated config.guess and config.sub so should build out of
568  the box on more Unix platforms.
569
570* (Unix version): Debian: added missing Build-Depends on xlibs-dev.
571
572* (Unix version): RPMs: give up supplying binary RPMs due to apparently
573  insurmountable technical problems.
[1a09e2c]574
[b462168]575Changes in 1.0.24:
576
577* cavern: fixed LEVEL (broken since around 1.0.8) and added test case.
578
579* cavern: corrected handling of declination in Compass DAT files and added test
580  case; also added tests for other aspects of Compass DAT file reading.
581
582* printps/printpcl: fixed blank page detection in some obscure cases.
583
584* Documentation: started manual section on working with Compass data files.
585
586* (Unix version): fixed compilation problems with aven and getopt.h on MacOS X
587  (and probably some other Unix versions).
588
589* (Unix version): Debian package now Build-Depends on gcc-3.2 and g++-3.2.
590
591Changes in 1.0.23:
592
593* Documentation: include 3d v3 file format description on MS Windows, MS DOS,
594  and RISC OS too; include PNG graphics for manual on MS Windows; minor updates
595  to manual.
596
597* Prefer wxWindows 2.4 if it's available.
598
599* (MacOS X version): detect MacOS X and look for MacOS X build of wxWindows;
600  automatically add resource fork to aven binary.
601
602* Disabled experimental support for Chinese (LANG=zh) - it isn't currently
603  working and makes the printer drivers unusable on Chinese versions of MS
604  Windows.
605
606* (Unix version): tweaked debian packaging.
607
608* cavern: Handling of "*:" at start of file wasn't fully fixed in 1.0.19.
609
610Changes in 1.0.22:
611
612* aven: Fixed handling of extended elevations (and other flat surveys) -
613  they are meant to be "locked flat" but this wasn't fully working before.
614
615* Documentation: 3d v3 file format description: fixed error in description of
616  codes 0x01-0x0e; include it in binary packages (not only with the source
617  code).
618
619Changes in 1.0.21:
620
621* cavern: when reading Compass DAT files, we now processes compass and clino
622  backsights, and recognise the "X" flag which indicates a leg should be
623  entirely ignored.  And we now report correct line number with errors in
624  Compass .MAK files.
625
626* cavern: if "*infer plumbs on", don't infer a plumb if the clino is
627  +/- 90 degrees, but the backclino isn't (and vice versa).
628
629* cavern: fixed 3dx output so it actually works with Chasm once more.
630
631* cavern: don't allocate extra space needed for producing 3dx output for
632  Chasm unless we're actually producing that output - saves about 8 bytes
633  per station.
634
635* cavern: removed slightly too keen sanity check which could misfire in very
636  unusual circumstances.
637
638* (MS Windows version): all .ico files except 3d.ico have been missing since
639  1.0.17 (or maybe 1.0.16) - fixed.  You wouldn't notice this if you installed
640  over an previous version.
641
642Changes in 1.0.20:
643
644* aven: update display when "Metric" or "Degrees" is toggled.
645
646* cavern: fixed handling of compass and clino corrections in Compass survey
647  data - these were interpreted as radians rather than degrees so the
648  correction was about 57 times too large!)
649
650* Improved handling of Compass PLT files - if the survey name is empty, don't
651  insert a survey separator character.
652
653* Documentation: fixed incorrect markup which resulted in a bogus footnote.
654
655Changes in 1.0.19:
656
657* cavern: you can now process Compass format survey data (.DAT and .MAK files) -
658  these can even be linked into a Survex dataset with "*include fulford.dat" or
659  "*include lech.mak" to allow processing of mixed datasets.
660
661* cavern: major speedup (up to 60%) when reading in survey data containing
662  a lot of stations in the same survey hierarchy level (which is how Compass
663  files are handled).
664
665* cavern: don't warn about a compass reading on a plumbed leg if the
666  plumb was inferred and the compass reading is zero.
667
668* cavern: reduced memory usage in code which reads a survey station name.
669
670* cavern: reported CPU time would go negative if cavern ran for more than
671  about 36 minutes (highly unlikely but not impossible on a slow machine
672  with a large, highly interconnect survey) - fixed.
673
674* cavern: avoid unnecessary work when --percentage isn't specified.
675
676* cavern: Writing "*:" at the start of a .svx file would crash cavern - fixed
677  and added test case.  This is an error anyway, but it shouldn't cause a
678  crash.
679
[89a6a1e]680* Don't distribute unused toolbar icons.
681
[b462168]682* Documentation: minor updates.
683
[27b8b59]684Changes in 1.0.18:
685
[b462168]686* (Unix version): Fixed "Process" action on .svx files.
[27b8b59]687
[b462168]688* (Unix version): File associations: if svxedit isn't installed, run gnome-edit
689  instead.
[27b8b59]690
[b462168]691* (Unix version): In Debian packages, now include file associations and file
[27b8b59]692  icons in the survex package rather than survex-aven.
693
[b462168]694* (Unix version): File associations were missing from RPM packages; moved
[27b8b59]695  aven and svxedit man pages to their respective subpackages; moved aven icons
696  to the aven subpackage.
697
698* Documentation: added details of the 3d file format (version 3).
699
700* Updated TODO list.
701
702Changes in 1.0.17:
703
[b462168]704* (MS Windows version): Fixed "Open in SvxEdit" to work (and if tcl isn't
[27b8b59]705  install this action now falls back to using notepad).  SvxEdit now has
706  its own icon.
707
[b462168]708* (Unix version): Install mime types, icons, and file associations for Gnome.
[27b8b59]709  Note: at present GMC doesn't seem to notice new files being created (e.g.
710  Process on a .svx file creates .3d and .err files) - you have to manually
711  refresh the view.
712
713* Minor update to manual.
714
715Changes in 1.0.16:
716
[b462168]717* (MS Windows version): Really fixed bug introduced in 1.0.14 which often stops
[27b8b59]718  programs from finding the message files.
719
[b462168]720* (MS Windows version): Remove any existing "Open" file association for .svx
[27b8b59]721  files.
722
723Changes in 1.0.15:
724
[b462168]725* (MS Windows version): Fixed bug introduced in 1.0.14 which often stops
[27b8b59]726  programs from finding the message files.
727
[b462168]728* (MS Windows version): "Open in Notepad" is now the double-click action
[27b8b59]729  for .svx files once again, "Open in SvxEdit" is an action in the menu
730  obtained with the right mouse button.
731
732Changes in 1.0.14:
733
734* svxedit: This is a Survex data entry editor from the therion team.  It needs
735  tcl and wish installed - for MS Windows an installer is available for free
736  from Activeware.
737
[ee1ec59]738* Improved handling of Compass PLT files and CMAP xyz files - no longer change
739  dots to spaces in survey and station names - instead use a space as the
740  separator between survey name and station name.
[27b8b59]741
742* aven: when picking non-overlapping labels, show a slight preference to shorter
743  labels with the aim of displaying more labels.
744
745* aven: fixed hard to notice problem which could cause the cave to appear
746  tilted sideways after a lot of manipulation.
747
748* cavern: Modest speed improvement (0.5% for sample dataset).
[ee1ec59]749
750* cavern: fixed a rarely sighted bug which caused erroneous error about some
[21c226e]751  stations not being attached to a fixed point.
752
[e7576f6]753* cavern: fixed clino readings and DIRECTION to work in interleaved data.
[21c226e]754
[ee1ec59]755* cavern: improved error reporting when an invalid value is given for a
756  DIRECTION reading.
757
[42d23c5]758* cavern: fixed "singular matrix" error when very low SDs were specified.
759
[27b8b59]760* print*: if the --raw is used, the survey can now use the space this would
761  have taken up.
762
763* Reading of ASCII 3d files now copes with MSDOS/MS Windows line endings
764  once again.  Added regression test for this.
765
[b462168]766* (MS Windows version): Programs run from the command line now find message
[27b8b59]767  files without SURVEXHOME needing to be set.
768
[21c226e]769* Updated documentation.
770
771Changes in 1.0.13:
772
773* aven: Fixed bug which caused the occasional spurious leg to be shown
774  connecting arbitrary stations.
[27b8b59]775
[21c226e]776* extend: try to extend along a survey, and make breaks where other surveys
777  join.
778
779* cavern: Number reading code reworked to allow repeat readings to be
780  supported, but the actual repeat reading code is currently disabled,
781  and everything should work exactly as before.
782
783* Experimental support for Chinese (LANG=zh) - only a few messages are
784  currently translated.
785
[50b0c7f]786Changes in 1.0.12:
787
[950e261]788* diffpos: fixed to work on 64bit architectures.
789
[dd5a89c]790* sorterr: fixed to work with more than 1024 traverses.
791
[abd126e]792* Fixed handling of iso-8859-2 character set and MS Windows code page 1250
793  (both cover Eastern European languages).
[27b8b59]794
[b462168]795* (MS Windows version): install file associations for Compass .plt and .plf
[f3d5b20]796  files and for CMAP .xyz files.  Also install the file icon for .plt and
797  .plf files in case Compass isn't installed (thanks to Larry Fish for
798  permission to include the icon).
799
800* (Unix version): running an installed program with an explicit path works
801  again.
802
803* (Unix version): xcaverot: automatically switch on PDA mode if the screen is
[15d7cc1]804  less than 640 pixels wide or less than 480 pixels high.
[f3d5b20]805
806* (Unix version): minor portability improvements.
807
[50b0c7f]808* Updates to Portuguese translation - all translations are now up-to-date.
809
[b8c4913]810Changes in 1.0.11:
811
[496a208]812* aven: improvements in 1.0.10 to the file type selector only work properly
813  on MS Windows, and with wxGtk >= 2.3 on Unix (the latest stable release is
814  2.2.9 where this doesn't work).  Fixed to work as well as possible on 2.2.9,
815  and as intended on 2.3.
816
[52634cc]817* aven: fixed so that loading PLT files works regardless of the current locale
818  (previously it would fail for locales where the decimal character wasn't
819  '.').
820
[7757a4ed]821* aven: key actions during autorotation no longer temporarily pause
822  autorotation.
823
[cc9150c]824* aven: switching to plan or elevation while rotating is now smooth.
825
826* aven: removed undocumented and confusing "free rotation mode".
827
828* (MS Windows version): aven: focus now set correctly after loading a file by
829  double-clicking or from the command line.
830
[a3326288]831* cad3d: write dummy passage dimensions to .plt files to avoid Compass bug.
832
[ca4058d]833* printwin/printps: now support coloured printouts.
834
[a3326288]835* print*: fixed to work correctly with PLT files.
836
837* extend: fixed to work correctly with PLT files.
[388ad50]838
[d275723]839* Updates to Italian translation.
840
[0f125da]841* Minor documentation updates.
842
[5215b99]843Changes in 1.0.10:
844
[6097cd2]845* (MS Windows version): aven: fixed assert failure upon turning on station
846  names.
847
[c01c332]848* aven: only add a file to the list of recently used files if it was opened
849  successfully.
850
[d16db18]851* aven: recognise ".plf" as a Compass PLT file too; and on Unix list "*.PLT",
852  "*.PLF", "*.XYZ", and "*.3D" as well as the lowercase versions to help people
853  who transfer files from MSDOS/MS Windows.
854
[cfcfd28]855* cavern: fixed bogus warning triggered by "*begin abc.def" (I'm not sure
856  that this should be valid, but the warning given wasn't appropriate).
857
[a9ab65a]858* Fixed scaling problem when reading PLT file (feet->metres conversion
859  factor was being applied backwards!)
860
[47e4a2e]861* Fixed potential problem when reading or writing a 3d file which couldn't
862  be opened.
863
[5215b99]864* Translate dots to spaces in survey names in Compass PLT files.
865
[ef59f5e]866* Better handling of PLT files which have a D command before any M command.
867
[c01c332]868* Updates to German and Italian translations.
[3bf737e]869
[f4276af]870Changes in 1.0.9:
871
[e3dfce4]872* aven: Fixed jerky start when auto-rotation begins.
873
874* cavern: Fixed Direction reading - bug previously made it unusable.
[f4276af]875
[6317ee2]876* (MS Windows version): cad3d: fixed broken PLT output (had a double CR at the
877  end of each line).
878
[161e268]879* (Unix version): RPMs now have the docs in /usr/share/doc and the man pages
880  in /usr/share/man to conform with the FHS (and where RedHat packages put
881  them).
882
[06e94a8]883* Updates to French, Spanish, Catalan, and Slovak translations.
[b10788f]884
[732b9b0]885Changes in 1.0.8:
886
[b6de07d]887* Slovak translation added; updated German, Catalan, and Spanish translations.
888
[fa42426]889* aven: reduced memory usage by around 25% and increased speed and
890  responsiveness.
[cd6ea75]891
[a8e9fde]892* aven: rate of rotation and switching between plan and elevation now adjusted
893  to the speed of redraw, so aven behaves in a similar way independent of the
894  speed of the computer or size of the survey.
895
[75993b9]896* aven: provide list of most recently loaded files (preserved between runs of
897  the program).
[6804731]898
899* aven: settings for "Metric" and "Degrees" are preserved between runs.
[732b9b0]900
[8ac4406]901* aven: moved some menu items from "View" to "Controls" as they probably
902  belong there and the "View" menu was getting out of hand.
903
[c8c116c]904* aven: cursor keys now translate cave in the same way the mouse does (i.e. now
905  work as in caverot and xcaverot).
906
[6df24ee]907* aven: eliminated the "twinkling label" effect when dragging the cave with the
908  right mouse button.
909
[fa42426]910* aven: the measuring line moves much more smoothly now: the mouse cursor now
911  snaps to the nearest station, rather than just a near station; and when the
912  line moves, we now only redraw the affected area of the window.
[2173dbd]913
[b6de07d]914* aven: resolved annoying limit on zooming in on large surveys.  This was a
915  crude way of preventing random lines due to overflow in the windowing system.
916  Aven now clips lines itself at high zoom levels, and limits zoom in to
917  approximately 1mm/pixel.
918
919* aven: zoom in/out with keyboard wasn't subject to any limits - now restricted
920  to sane values as with zoom in/out with the mouse.
921
[5fa68cc5]922* print*: added --raw switch to turn of info box, scale bar, and page footer.
923  This can be useful if you want to import the output into another application.
[1a09e2c]924
[5b7c1b7]925* print*: improved output when --no-border is used.
[3fb572e]926
[2001db9]927* printpcl/printdm: Added new .ini setting "font_bitmap" which allows the user
928  to choose between alternative fonts.  Current we supply "default" and "bold".
929
[fa42426]930* printps/printhpgl: Fixed --skip-blanks which would incorrectly skip non-blank
931  pages on rare occasions.
932
[11e919a]933* cavern: added support for BackCompass and BackClino.
[5b7c1b7]934
[fa42426]935* cavern: implemented "*units clino percent".
[c9eb197]936
[0580c6a]937* cavern: added "*infer exports on".  Any stations seen while this is on will
[c00c74a9]938  have the necessary *export-s inferred when accessed from outside their
939  own survey.  This allows linking a survey which uses *export to one which
940  doesn't.  It's also useful for a maze cave where so many stations can
941  be linked to that listing them explicitly isn't desirable.
942
[fa42426]943* cavern: N-S, E-W, and vertical ranges now only count stations which are in
944  underground surveys.
945
[0b71cfc]946* cavern: *infer plumbs wasn't inferring -90 to be DOWN - fixed.
947
[c00c74a9]948* cavern: *infer was giving an internal error if the argument was unknown -
949  now it gives the correct error message.
950
[fa42426]951* cavern: fixed handling of omitted clino readings when OMIT is *set to be
952  different from MINUS and PLUS (new test omitclino).
953
[b14f44f]954* cavern: fixed a bogus warning for any station which was only used in a line
955  of data which was rejected because of an error.
956
[fa42426]957* cavern: added error if the *units factor is zero (e.g. "*units tape 0 feet").
958
[b14f44f]959* cavern: removed the ill-thought-out and never implemented LENGTHOUTPUT
960  and ANGLEOUTPUT quantities.
961
[770157e]962* cavern: resolved mismatch between bcra5.svx and the default SDs, and the
963  odd values in bcra3.svx.  We are now interpreting the BCRA limits as 2
964  standard deviations (previously bcra5.svx used 3 sds, bcra3 used 3.33 sds for
965  tape and position, and .75 sds for compass and clino, and cavern used 1 sd
966  by default).
967
[a20b208]968* ChangeLog now only includes entries since the previous release (the full file
[9cc3854]969  is 220K or so, and of interest to very few people).  MSDOS and MS Windows
[b14f44f]970  versions now comfortably fit on a 1.44M floppy once again.
[9cc3854]971
[b6de07d]972* Test suite now checks that all programs will run successfully with "--help"
973  and with "--version".  This should avoid problems such as that which broke
974  the printer drivers in 1.0.4-1.0.6.
[a20b208]975
[fa42426]976* (Unix version): uninstalled binaries now use the path they are run with to
977  find support files, which means SURVEXHOME is no longer required, and has
978  been removed.
979
[7c41b21]980Changes in 1.0.7:
981
982* print*: halted with a failed assertion in 1.0.4-1.0.6.
983
[cd8d79a]984Changes in 1.0.6:
985
986* aven: "Reverse Controls" now works as in xcaverot and caverot.
987
988* aven: free rotation mode (engage by pressing control while left dragging,
989  exit with Delete) improved.
990
[30987bd]991* aven: using File->Open when a file was already loaded caused a crash
992  if a station was "grey highlighted" in the survey tree - fixed.
993
[e98af57]994* aven: added hourglass for "find" operation.
995
[0edb0d0]996* aven: reenabled loading of files by drag-and-drop (accidentally disabled
997  in 1.0.4 and 1.0.5).
998
[303a525]999* aven: improved handling of flat surveys (e.g. output of extend, surveys
1000  with no clino information).
1001
[12d0d1b]1002* aven: surveys with stations but no legs no longer cause the labels and
1003  crosses buttons to behave oddly.
1004
[2c30188]1005* aven: removed quite a bit of unused and superfluous code.
1006
[3d5fb53]1007* Spell-checked documentation.
1008
[c637fad]1009Changes in 1.0.5:
1010
1011* Fixed bug in img_open_survey() which could cause a crash if you tried to
[88c780d]1012  open an unrecognised file (i.e. not .3d, .pos, .plt, or .xyz format).
1013
1014* North and East were the wrong way round when reading in .plt files.
[c637fad]1015
[5173649]1016* cad3d: Improved .plt file output a little - there's probably enough file
1017  structure for Compass to read them now.
1018
[f9dc4a0]1019* Documentation updates.
1020
[ea1c342]1021Changes in 1.0.4:
1022
[64511c0]1023* extend: previously only kept one name for an equated group of stations in the
1024  extended .3d file; now keeps all the names.
1025
[b387524]1026* cad3d: if an output filename is given, use its extension to pick the default
1027  output format.
1028
[ba2c5b1]1029* aven: movement with keyboard is now accelerated by Shift as in caverot.
1030
[f3ed07f]1031* print*: --no-borders fixed to work as documented; --no-cutlines added to
1032  turn off the dashed lines where pages join on multi-page printouts.
[80f17e0]1033
[189f179]1034* aven: tracked down two uninitialised variables which seems to fix the
1035  failure to load a survey on startup which some people have been experiencing
1036  on Microsoft Windows.
1037
1038* aven: code cleaned up - should improve performance a little.
[9f3e5df]1039
1040* img routines: img_rewind() now returns a value indicating success/failure.
1041
[f1c7c9c7]1042* Improvements to .plt file reading, notably that distances in the file are
1043  now interpreted as being in feet rather than metres.  Also .plt files should
1044  now be recognised even with a different extension, and we cope with an odd
1045  special case better.
1046
1047* Added support for reading CMAP XYZ files.  There are two variants of these
1048  - the "shot" format is fully implemented, the "station" format currently
1049  just reads the station names and positions - the legs are ignored (sadly
1050  the sample files I have do not match the format specification).
[4ebc557]1051
[80f17e0]1052* (MacOS X version): aven: aven now builds on MacOS X - we just need to sort
[64511c0]1053  out packaging now...
[ea1c342]1054
[be48ac6]1055* (MSDOS version): upgraded graphics library used to Allegro 4.0.1.
1056
[fe16ba3]1057* Documentation updates.
[a7e3295]1058
[febe041]1059Changes in 1.0.3:
1060
[7a89dc2]1061* aven: you can now select distances to be displayed in feet (or miles when
1062  you zoom right out) instead of metres, and angles to be in grads instead
1063  of degrees.
1064
1065* aven: show altitude of mouse pointer when in elevation view.
1066
[febe041]1067* cad3d: fixed bug which caused --plt to crash on some platforms.
1068
[3857e321]1069* print*: added "Printing to `XXX'..." message to say where output is being
1070  written.
1071
[a8fa00a]1072* Updated French translation; minor updates to other translations (mostly
1073  sorting out clashing menu shortcuts in aven).
[e3a14ae]1074
[43db339]1075* (Unix version): assorted portability tweaks.
1076
[745433f]1077Changes in 1.0.2:
1078
[4783405]1079* printdm/printpcl/printwin: take notice of font_size_labels setting in
1080  print.ini etc.
1081
[107b8bd]1082* cavern: Topofil can now be used with DIVING and CYLPOLAR styles; TOPOFIL
1083  style is now synonymous with NORMAL.
1084
1085* cavern: *INFER EQUATES and *DATA TOPOFIL now work together correctly.
1086
[c2211a5]1087* cavern: *FIX with 3 standard deviations but no covariances now works.
1088
[f73bb48]1089* (MacOS X version): command line programs now build.  We're working on Aven.
[745433f]1090
[7fc1465]1091* Updates to the Catalan and Spanish translations.
1092
[4783405]1093* xcaverot: documented environmental variables XCAVEROT_INDICATOR_RADIUS and
1094  XCAVEROT_FONTNAME.
1095
[e1b99fc]1096* cad3d: added --plt option to produce crude approximation to Compass .plt
1097  files - should be good enough for reading into Carto.
1098
[ad4eaf3f]1099* img library enhanced to allow Compass .plt files to be read as if they were
1100  .3d files.
1101
[3217572]1102Changes in 1.0.1:
1103
[7fc1465]1104* (MS Windows version): printwin: fixed sizes of cross and page alignment
[de5f18d]1105  ticks.
[7be0ba8]1106
[5d38036]1107* Updates to the Portuguese and Italian translations.
1108
[c51c50a]1109Changes in 1.0.0:
[4b4bd47]1110
[4d3dfdf]1111* Fixed --survey option supported by many programs which was broken in 0.99.
1112
[c51c50a]1113* aven: altered colours of "fixed points" and "entrances" buttons to match
1114  the coloured blobs used to indicate them.
1115
[de5f18d]1116* (MS Windows version): aven: changed current point highlighting in the
[35001ee]1117  survey tree to use a light grey background rather than bold (bold causes
1118  the text to "wriggle" as the highlight runs up or down).
1119
[1cc6cc5]1120* (MS Windows version): file icons now have transparent backgrounds.
1121
[c51c50a]1122* survex: removed conversion wrapper - you should use "cavern file.svx"
1123  instead of "survex file.svx".
1124
[fe282c2]1125* (Unix version): GCC 2.95 sometimes fails with an internal error when trying
1126  to compile gfxcore.cc - if it does, the Makefile will now try recompiling
1127  with a lower optimisation level.
1128
[8f2c870]1129* (Unix version): when doing an "in directory" build from source, the HTML
1130  manual is now installed in its own subdirectory as when doing a non
1131  "in directory" build.
1132
[c51c50a]1133* German translation now completely up-to-date.
