<h1>Changes in 1.0.32:
</h1>
<ul><li><p>aven: Fixed font sizes in "Print Preview" and printouts.
</p></li><li><p>aven: In the print setup dialog, replaced "Orientation" radio buttons with
"Plan" and "Elevation" buttons.
</p></li><li><p>aven: Fixed info box on printouts of elevations, tilted views, and
extend elevations.
</p></li><li><p>aven: Added "fit on one page" option, and make it the default.
</p></li><li><p>aven: Reorder "Cancel", "Preview", "Print" buttons and make "Print" the
default button.
</p></li><li><p>aven: Read settings back from the print dialog when the "Print" button is
pressed (was only done for "Preview" previously).
</p></li><li><p>aven: Sorted out the initial size of the "Print Preview" window.
</p></li><li><p>aven: Fixed the window manager's close button on the "Print Preview" window
- previously this was being ignored.
</p></li><li><p>aven: Sorted out initial survey scaling when loading a survey at startup.
</p></li><li><p>aven: Fixed the measuring line to work better when the survey tree is
manipulated with keys.  Tweaked redrawing of the measuring line to be a
smidgen more efficient.  Fixed the blob and ring size which were one
pixel too small on Windows.
</p></li><li><p>aven: Added "System Information:" section to the "About" dialog to hold
information useful when reporting bugs.  Currently it contains the wxWindows
version, OS version, and colour depth information.
</p></li><li><p>aven: Changed the "About" dialog's "Close" button to be "OK" for consistency
with pretty much every other application.
</p></li><li><p>aven: Added "File-&gt;Export as..." which integrates cad3d's functionality
within aven.
</p></li><li><p>aven: Updated a few icons.
</p></li><li><p>cad3d: Added SVG export support from John Pybus
</p></li><li><p>(Unix version): Fixed to allow compilation with GCC 3.4
</p></li><li><p>(MS Windows version): Upgrade to using innosetup 4 for the installer
(we were using innosetup 2).  This results in a much smaller download
and the installer now translates itself into the currently set language.
The installer will no longer work on Windows NT 3.51, but I seriously
doubt anyone is still using that...
</p></li><li><p>Updates to German translation.
</p></li></ul><h1>Changes in 1.0.31:
</h1>
<ul><li><p>(MS Windows version): Fixed problems with the new printing code by building
with a newer version of wxWindows (2.5.2 instead of 2.4.1).
</p></li><li><p>aven: Fixed grid menu item so that it always correctly reflects whether the
grid is enabled or not.
</p></li><li><p>aven: Minor improvements to appearance of a few toolbar icons.
</p></li><li><p>Updates to Catalan, French, Italian, Romanian, Slovak, and Spanish
translations.
</p></li><li><p>cavern: Fixed Romanian message which was appearing in English .err files.
</p></li></ul><h1>Changes in 1.0.30:
</h1>
<ul><li><p>aven: Added printing directly from Aven!
</p></li><li><p>aven: Fixed memory leak when showing the "About" dialog.
</p></li><li><p>(MacOS X version): Now installable from a disk image package.
</p></li><li><p>cavern: Equates are no longer considered when deciding which stations are
flagged as surface and underground.
</p></li><li><p>Romanian translation mostly completed.
</p></li><li><p>(Unix version): Debian: Minor packaging tweaks.
</p></li></ul><h1>Changes in 1.0.29:
</h1>
<ul><li><p>cad3d: Fixed problem with DXF files which stopped them loading with some
drawing packages (introduced in 1.0.27).
</p></li><li><p>aven: Changed File-&gt;Exit to File-&gt;Quit.
</p></li><li><p>Removed some unused messages from the message files.
</p></li><li><p>(Unix version): Fixed SRPMs to build on RedHat 9 and Fedora Core 1 (patch
from John Pybus).
</p></li><li><p>Romanian translation started.
</p></li><li><p>(Unix version): Debian: Fixed new lintian warnings about missing quotes in
menu files.
</p></li></ul><h1>Changes in 1.0.28:
</h1>
<ul><li><p>Fixed 3d file reading code to fix incorrect unpacking of compressed station
names in a rare case.  Also checked other rare cases work correctly.
</p></li></ul><h1>Changes in 1.0.27:
</h1>
<ul><li><p>cad3d: DXF output now puts surface legs, stations, and labels in separate
layers.
</p></li><li><p>(Unix version): distribute desc-svxedit.txt.
</p></li></ul><h1>Changes in 1.0.26:
</h1>
<ul><li><p>cavern: Fixed interleaved topofil data style - the length was always being
calculated as zero.
</p></li><li><p>(Unix version): aven: "All Files" now shows files without extensions too.
</p></li><li><p>aven: added Ctrl+Q as shortcut for File-&gt;Exit.
</p></li><li><p>aven: depth colouring now uses a proper colour gradient.
</p></li><li><p>(MacOS X version): aven: the keyboard and mouse now work!  It turns out that
we must apply resources *after* installing.
</p></li><li><p>(MacOS X version): aven: now works when run from the MacOS X Finder.
</p></li><li><p>(MacOS X version): look for message files and other resources relative to the
binaries so that the user can install Survex from a disk image in the location
of their choice.
</p></li><li><p>(MacOS X version): fixed not to try to build aven if wxWindows isn't
installed.
</p></li><li><p>cad3d: fixed -e and -r options to not crash (the long versions have always
worked).
</p></li><li><p>extend: fixed to initialise an internal structure - failing to do so was
probably causing crashes on some platforms.
</p></li><li><p>Fixed standard graphics for "Note", "Warning", etc in the PostScript manual.
</p></li><li><p>Documentation updated.
</p></li><li><p>(Unix version): fixed svxedit man page which previously contained xcaverot
documentation!
</p></li><li><p>test suite: check that cavern doesn't report "nan" or "NaN" for any values.
</p></li><li><p>(Unix version): fixed configure --enable-defaultlang=XX to work.
</p></li><li><p>(Unix version): fixed configure code to turn on lots of GCC warnings and fixed
most of them.
</p></li><li><p>(MS Windows version): assorted tweaks to allow building with MS Visual C/C++.
</p></li></ul><h1>Changes in 1.0.25:
</h1>
<ul><li><p>(MacOS X version): hopefully fixed building of aven.
</p></li><li><p>(Unix version): updated config.guess and config.sub so should build out of
the box on more Unix platforms.
</p></li><li><p>(Unix version): Debian: added missing Build-Depends on xlibs-dev.
</p></li><li><p>(Unix version): RPMs: give up supplying binary RPMs due to apparently
insurmountable technical problems.
</p></li></ul><h1>Changes in 1.0.24:
</h1>
<ul><li><p>cavern: fixed LEVEL (broken since around 1.0.8) and added test case.
</p></li><li><p>cavern: corrected handling of declination in Compass DAT files and added test
case; also added tests for other aspects of Compass DAT file reading.
</p></li><li><p>printps/printpcl: fixed blank page detection in some obscure cases.
</p></li><li><p>Documentation: started manual section on working with Compass data files.
</p></li><li><p>(Unix version): fixed compilation problems with aven and getopt.h on MacOS X
(and probably some other Unix versions).
</p></li><li><p>(Unix version): Debian package now Build-Depends on gcc-3.2 and g++-3.2.
</p></li></ul><h1>Changes in 1.0.23:
</h1>
<ul><li><p>Documentation: include 3d v3 file format description on MS Windows, MS DOS,
and RISC OS too; include PNG graphics for manual on MS Windows; minor updates
to manual.
</p></li><li><p>Prefer wxWindows 2.4 if it's available.
</p></li><li><p>(MacOS X version): detect MacOS X and look for MacOS X build of wxWindows;
automatically add resource fork to aven binary.
</p></li><li><p>Disabled experimental support for Chinese (LANG=zh) - it isn't currently
working and makes the printer drivers unusable on Chinese versions of MS
Windows.
</p></li><li><p>(Unix version): tweaked debian packaging.
</p></li><li><p>cavern: Handling of "*:" at start of file wasn't fully fixed in 1.0.19.
</p></li></ul><h1>Changes in 1.0.22:
</h1>
<ul><li><p>aven: Fixed handling of extended elevations (and other flat surveys) -
they are meant to be "locked flat" but this wasn't fully working before.
</p></li><li><p>Documentation: 3d v3 file format description: fixed error in description of
codes 0x01-0x0e; include it in binary packages (not only with the source
code).
</p></li></ul><h1>Changes in 1.0.21:
</h1>
<ul><li><p>cavern: when reading Compass DAT files, we now processes compass and clino
backsights, and recognise the "X" flag which indicates a leg should be
entirely ignored.  And we now report correct line number with errors in
Compass .MAK files.
</p></li><li><p>cavern: if "*infer plumbs on", don't infer a plumb if the clino is
+/- 90 degrees, but the backclino isn't (and vice versa).
</p></li><li><p>cavern: fixed 3dx output so it actually works with Chasm once more.
</p></li><li><p>cavern: don't allocate extra space needed for producing 3dx output for
Chasm unless we're actually producing that output - saves about 8 bytes
per station.
</p></li><li><p>cavern: removed slightly too keen sanity check which could misfire in very
unusual circumstances.
</p></li><li><p>(MS Windows version): all .ico files except 3d.ico have been missing since
1.0.17 (or maybe 1.0.16) - fixed.  You wouldn't notice this if you installed
over an previous version.
</p></li></ul><h1>Changes in 1.0.20:
</h1>
<ul><li><p>aven: update display when "Metric" or "Degrees" is toggled.
</p></li><li><p>cavern: fixed handling of compass and clino corrections in Compass survey
data - these were interpreted as radians rather than degrees so the
correction was about 57 times too large!)
</p></li><li><p>Improved handling of Compass PLT files - if the survey name is empty, don't
insert a survey separator character.
</p></li><li><p>Documentation: fixed incorrect markup which resulted in a bogus footnote.
</p></li></ul><h1>Changes in 1.0.19:
</h1>
<ul><li><p>cavern: you can now process Compass format survey data (.DAT and .MAK files) -
these can even be linked into a Survex dataset with "*include fulford.dat" or
"*include lech.mak" to allow processing of mixed datasets.
</p></li><li><p>cavern: major speedup (up to 60%) when reading in survey data containing
a lot of stations in the same survey hierarchy level (which is how Compass
files are handled).
</p></li><li><p>cavern: don't warn about a compass reading on a plumbed leg if the
plumb was inferred and the compass reading is zero.
</p></li><li><p>cavern: reduced memory usage in code which reads a survey station name.
</p></li><li><p>cavern: reported CPU time would go negative if cavern ran for more than
about 36 minutes (highly unlikely but not impossible on a slow machine
with a large, highly interconnect survey) - fixed.
</p></li><li><p>cavern: avoid unnecessary work when --percentage isn't specified.
</p></li><li><p>cavern: Writing "*:" at the start of a .svx file would crash cavern - fixed
and added test case.  This is an error anyway, but it shouldn't cause a
crash.
</p></li><li><p>Don't distribute unused toolbar icons.
</p></li><li><p>Documentation: minor updates.
</p></li></ul><h1>Changes in 1.0.18:
</h1>
<ul><li><p>(Unix version): Fixed "Process" action on .svx files.
</p></li><li><p>(Unix version): File associations: if svxedit isn't installed, run gnome-edit
instead.
</p></li><li><p>(Unix version): In Debian packages, now include file associations and file
icons in the survex package rather than survex-aven.
</p></li><li><p>(Unix version): File associations were missing from RPM packages; moved
aven and svxedit man pages to their respective subpackages; moved aven icons
to the aven subpackage.
</p></li><li><p>Documentation: added details of the 3d file format (version 3).
</p></li><li><p>Updated TODO list.
</p></li></ul><h1>Changes in 1.0.17:
</h1>
<ul><li><p>(MS Windows version): Fixed "Open in SvxEdit" to work (and if tcl isn't
install this action now falls back to using notepad).  SvxEdit now has
its own icon.
</p></li><li><p>(Unix version): Install mime types, icons, and file associations for Gnome.
Note: at present GMC doesn't seem to notice new files being created (e.g.
Process on a .svx file creates .3d and .err files) - you have to manually
refresh the view.
</p></li><li><p>Minor update to manual.
</p></li></ul><h1>Changes in 1.0.16:
</h1>
<ul><li><p>(MS Windows version): Really fixed bug introduced in 1.0.14 which often stops
programs from finding the message files.
</p></li><li><p>(MS Windows version): Remove any existing "Open" file association for .svx
files.
</p></li></ul><h1>Changes in 1.0.15:
</h1>
<ul><li><p>(MS Windows version): Fixed bug introduced in 1.0.14 which often stops
programs from finding the message files.
</p></li><li><p>(MS Windows version): "Open in Notepad" is now the double-click action
for .svx files once again, "Open in SvxEdit" is an action in the menu
obtained with the right mouse button.
</p></li></ul><h1>Changes in 1.0.14:
</h1>
<ul><li><p>svxedit: This is a Survex data entry editor from the therion team.  It needs
tcl and wish installed - for MS Windows an installer is available for free
from Activeware.
</p></li><li><p>Improved handling of Compass PLT files and CMAP xyz files - no longer change
dots to spaces in survey and station names - instead use a space as the
separator between survey name and station name.
</p></li><li><p>aven: when picking non-overlapping labels, show a slight preference to shorter
labels with the aim of displaying more labels.
</p></li><li><p>aven: fixed hard to notice problem which could cause the cave to appear
tilted sideways after a lot of manipulation.
</p></li><li><p>cavern: Modest speed improvement (0.5% for sample dataset).
</p></li><li><p>cavern: fixed a rarely sighted bug which caused erroneous error about some
stations not being attached to a fixed point.
</p></li><li><p>cavern: fixed clino readings and DIRECTION to work in interleaved data.
</p></li><li><p>cavern: improved error reporting when an invalid value is given for a
DIRECTION reading.
</p></li><li><p>cavern: fixed "singular matrix" error when very low SDs were specified.
</p></li><li><p>print*: if the --raw is used, the survey can now use the space this would
have taken up.
</p></li><li><p>Reading of ASCII 3d files now copes with MSDOS/MS Windows line endings
once again.  Added regression test for this.
</p></li><li><p>(MS Windows version): Programs run from the command line now find message
files without SURVEXHOME needing to be set.
</p></li><li><p>Updated documentation.
</p></li></ul><h1>Changes in 1.0.13:
</h1>
<ul><li><p>aven: Fixed bug which caused the occasional spurious leg to be shown
connecting arbitrary stations.
</p></li><li><p>extend: try to extend along a survey, and make breaks where other surveys
join.
</p></li><li><p>cavern: Number reading code reworked to allow repeat readings to be
supported, but the actual repeat reading code is currently disabled,
and everything should work exactly as before.
</p></li><li><p>Experimental support for Chinese (LANG=zh) - only a few messages are
currently translated.
</p></li></ul><h1>Changes in 1.0.12:
</h1>
<ul><li><p>diffpos: fixed to work on 64bit architectures.
</p></li><li><p>sorterr: fixed to work with more than 1024 traverses.
</p></li><li><p>Fixed handling of iso-8859-2 character set and MS Windows code page 1250
(both cover Eastern European languages).
</p></li><li><p>(MS Windows version): install file associations for Compass .plt and .plf
files and for CMAP .xyz files.  Also install the file icon for .plt and
.plf files in case Compass isn't installed (thanks to Larry Fish for
permission to include the icon).
</p></li><li><p>(Unix version): running an installed program with an explicit path works
again.
</p></li><li><p>(Unix version): xcaverot: automatically switch on PDA mode if the screen is
less than 640 pixels wide or less than 480 pixels high.
</p></li><li><p>(Unix version): minor portability improvements.
</p></li><li><p>Updates to Portuguese translation - all translations are now up-to-date.
</p></li></ul><h1>Changes in 1.0.11:
</h1>
<ul><li><p>aven: improvements in 1.0.10 to the file type selector only work properly
on MS Windows, and with wxGtk &gt;= 2.3 on Unix (the latest stable release is
2.2.9 where this doesn't work).  Fixed to work as well as possible on 2.2.9,
and as intended on 2.3.
</p></li><li><p>aven: fixed so that loading PLT files works regardless of the current locale
(previously it would fail for locales where the decimal character wasn't
'.').
</p></li><li><p>aven: key actions during autorotation no longer temporarily pause
autorotation.
</p></li><li><p>aven: switching to plan or elevation while rotating is now smooth.
</p></li><li><p>aven: removed undocumented and confusing "free rotation mode".
</p></li><li><p>(MS Windows version): aven: focus now set correctly after loading a file by
double-clicking or from the command line.
</p></li><li><p>cad3d: write dummy passage dimensions to .plt files to avoid Compass bug.
</p></li><li><p>printwin/printps: now support coloured printouts.
</p></li><li><p>print*: fixed to work correctly with PLT files.
</p></li><li><p>extend: fixed to work correctly with PLT files.
</p></li><li><p>Updates to Italian translation.
</p></li><li><p>Minor documentation updates.
</p></li></ul><h1>Changes in 1.0.10:
</h1>
<ul><li><p>(MS Windows version): aven: fixed assert failure upon turning on station
names.
</p></li><li><p>aven: only add a file to the list of recently used files if it was opened
successfully.
</p></li><li><p>aven: recognise ".plf" as a Compass PLT file too; and on Unix list "*.PLT",
"*.PLF", "*.XYZ", and "*.3D" as well as the lowercase versions to help people
who transfer files from MSDOS/MS Windows.
</p></li><li><p>cavern: fixed bogus warning triggered by "*begin abc.def" (I'm not sure
that this should be valid, but the warning given wasn't appropriate).
</p></li><li><p>Fixed scaling problem when reading PLT file (feet-&gt;metres conversion
factor was being applied backwards!)
</p></li><li><p>Fixed potential problem when reading or writing a 3d file which couldn't
be opened.
</p></li><li><p>Translate dots to spaces in survey names in Compass PLT files.
</p></li><li><p>Better handling of PLT files which have a D command before any M command.
</p></li><li><p>Updates to German and Italian translations.
</p></li></ul><h1>Changes in 1.0.9:
</h1>
<ul><li><p>aven: Fixed jerky start when auto-rotation begins.
</p></li><li><p>cavern: Fixed Direction reading - bug previously made it unusable.
</p></li><li><p>(MS Windows version): cad3d: fixed broken PLT output (had a double CR at the
end of each line).
</p></li><li><p>(Unix version): RPMs now have the docs in /usr/share/doc and the man pages
in /usr/share/man to conform with the FHS (and where RedHat packages put
them).
</p></li><li><p>Updates to French, Spanish, Catalan, and Slovak translations.
</p></li></ul><h1>Changes in 1.0.8:
</h1>
<ul><li><p>Slovak translation added; updated German, Catalan, and Spanish translations.
</p></li><li><p>aven: reduced memory usage by around 25% and increased speed and
responsiveness.
</p></li><li><p>aven: rate of rotation and switching between plan and elevation now adjusted
to the speed of redraw, so aven behaves in a similar way independent of the
speed of the computer or size of the survey.
</p></li><li><p>aven: provide list of most recently loaded files (preserved between runs of
the program).
</p></li><li><p>aven: settings for "Metric" and "Degrees" are preserved between runs.
</p></li><li><p>aven: moved some menu items from "View" to "Controls" as they probably
belong there and the "View" menu was getting out of hand.
</p></li><li><p>aven: cursor keys now translate cave in the same way the mouse does (i.e. now
work as in caverot and xcaverot).
</p></li><li><p>aven: eliminated the "twinkling label" effect when dragging the cave with the
right mouse button.
</p></li><li><p>aven: the measuring line moves much more smoothly now: the mouse cursor now
snaps to the nearest station, rather than just a near station; and when the
line moves, we now only redraw the affected area of the window.
</p></li><li><p>aven: resolved annoying limit on zooming in on large surveys.  This was a
crude way of preventing random lines due to overflow in the windowing system.
Aven now clips lines itself at high zoom levels, and limits zoom in to
approximately 1mm/pixel.
</p></li><li><p>aven: zoom in/out with keyboard wasn't subject to any limits - now restricted
to sane values as with zoom in/out with the mouse.
</p></li><li><p>print*: added --raw switch to turn of info box, scale bar, and page footer.
This can be useful if you want to import the output into another application.
</p></li><li><p>print*: improved output when --no-border is used.
</p></li><li><p>printpcl/printdm: Added new .ini setting "font_bitmap" which allows the user
to choose between alternative fonts.  Current we supply "default" and "bold".
</p></li><li><p>printps/printhpgl: Fixed --skip-blanks which would incorrectly skip non-blank
pages on rare occasions.
</p></li><li><p>cavern: added support for BackCompass and BackClino.
</p></li><li><p>cavern: implemented "*units clino percent".
</p></li><li><p>cavern: added "*infer exports on".  Any stations seen while this is on will
have the necessary *export-s inferred when accessed from outside their
own survey.  This allows linking a survey which uses *export to one which
doesn't.  It's also useful for a maze cave where so many stations can
be linked to that listing them explicitly isn't desirable.
</p></li><li><p>cavern: N-S, E-W, and vertical ranges now only count stations which are in
underground surveys.
</p></li><li><p>cavern: *infer plumbs wasn't inferring -90 to be DOWN - fixed.
</p></li><li><p>cavern: *infer was giving an internal error if the argument was unknown -
now it gives the correct error message.
</p></li><li><p>cavern: fixed handling of omitted clino readings when OMIT is *set to be
different from MINUS and PLUS (new test omitclino).
</p></li><li><p>cavern: fixed a bogus warning for any station which was only used in a line
of data which was rejected because of an error.
</p></li><li><p>cavern: added error if the *units factor is zero (e.g. "*units tape 0 feet").
</p></li><li><p>cavern: removed the ill-thought-out and never implemented LENGTHOUTPUT
and ANGLEOUTPUT quantities.
</p></li><li><p>cavern: resolved mismatch between bcra5.svx and the default SDs, and the
odd values in bcra3.svx.  We are now interpreting the BCRA limits as 2
standard deviations (previously bcra5.svx used 3 sds, bcra3 used 3.33 sds for
tape and position, and .75 sds for compass and clino, and cavern used 1 sd
by default).
</p></li><li><p>ChangeLog now only includes entries since the previous release (the full file
is 220K or so, and of interest to very few people).  MSDOS and MS Windows
versions now comfortably fit on a 1.44M floppy once again.
</p></li><li><p>Test suite now checks that all programs will run successfully with "--help"
and with "--version".  This should avoid problems such as that which broke
the printer drivers in 1.0.4-1.0.6.
</p></li><li><p>(Unix version): uninstalled binaries now use the path they are run with to
find support files, which means SURVEXHOME is no longer required, and has
been removed.
</p></li></ul><h1>Changes in 1.0.7:
</h1>
<ul><li><p>print*: halted with a failed assertion in 1.0.4-1.0.6.
</p></li></ul><h1>Changes in 1.0.6:
</h1>
<ul><li><p>aven: "Reverse Controls" now works as in xcaverot and caverot.
</p></li><li><p>aven: free rotation mode (engage by pressing control while left dragging,
exit with Delete) improved.
</p></li><li><p>aven: using File-&gt;Open when a file was already loaded caused a crash
if a station was "grey highlighted" in the survey tree - fixed.
</p></li><li><p>aven: added hourglass for "find" operation.
</p></li><li><p>aven: reenabled loading of files by drag-and-drop (accidentally disabled
in 1.0.4 and 1.0.5).
</p></li><li><p>aven: improved handling of flat surveys (e.g. output of extend, surveys
with no clino information).
</p></li><li><p>aven: surveys with stations but no legs no longer cause the labels and
crosses buttons to behave oddly.
</p></li><li><p>aven: removed quite a bit of unused and superfluous code.
</p></li><li><p>Spell-checked documentation.
</p></li></ul><h1>Changes in 1.0.5:
</h1>
<ul><li><p>Fixed bug in img_open_survey() which could cause a crash if you tried to
open an unrecognised file (i.e. not .3d, .pos, .plt, or .xyz format).
</p></li><li><p>North and East were the wrong way round when reading in .plt files.
</p></li><li><p>cad3d: Improved .plt file output a little - there's probably enough file
structure for Compass to read them now.
</p></li><li><p>Documentation updates.
</p></li></ul><h1>Changes in 1.0.4:
</h1>
<ul><li><p>extend: previously only kept one name for an equated group of stations in the
extended .3d file; now keeps all the names.
</p></li><li><p>cad3d: if an output filename is given, use its extension to pick the default
output format.
</p></li><li><p>aven: movement with keyboard is now accelerated by Shift as in caverot.
</p></li><li><p>print*: --no-borders fixed to work as documented; --no-cutlines added to
turn off the dashed lines where pages join on multi-page printouts.
</p></li><li><p>aven: tracked down two uninitialised variables which seems to fix the
failure to load a survey on startup which some people have been experiencing
on Microsoft Windows.
</p></li><li><p>aven: code cleaned up - should improve performance a little.
</p></li><li><p>img routines: img_rewind() now returns a value indicating success/failure.
</p></li><li><p>Improvements to .plt file reading, notably that distances in the file are
now interpreted as being in feet rather than metres.  Also .plt files should
now be recognised even with a different extension, and we cope with an odd
special case better.
</p></li><li><p>Added support for reading CMAP XYZ files.  There are two variants of these
- the "shot" format is fully implemented, the "station" format currently
just reads the station names and positions - the legs are ignored (sadly
the sample files I have do not match the format specification).
</p></li><li><p>(MacOS X version): aven: aven now builds on MacOS X - we just need to sort
out packaging now...
</p></li><li><p>(MSDOS version): upgraded graphics library used to Allegro 4.0.1.
</p></li><li><p>Documentation updates.
</p></li></ul><h1>Changes in 1.0.3:
</h1>
<ul><li><p>aven: you can now select distances to be displayed in feet (or miles when
you zoom right out) instead of metres, and angles to be in grads instead
of degrees.
</p></li><li><p>aven: show altitude of mouse pointer when in elevation view.
</p></li><li><p>cad3d: fixed bug which caused --plt to crash on some platforms.
</p></li><li><p>print*: added "Printing to `XXX'..." message to say where output is being
written.
</p></li><li><p>Updated French translation; minor updates to other translations (mostly
sorting out clashing menu shortcuts in aven).
</p></li><li><p>(Unix version): assorted portability tweaks.
</p></li></ul><h1>Changes in 1.0.2:
</h1>
<ul><li><p>printdm/printpcl/printwin: take notice of font_size_labels setting in
print.ini etc.
</p></li><li><p>cavern: Topofil can now be used with DIVING and CYLPOLAR styles; TOPOFIL
style is now synonymous with NORMAL.
</p></li><li><p>cavern: *INFER EQUATES and *DATA TOPOFIL now work together correctly.
</p></li><li><p>cavern: *FIX with 3 standard deviations but no covariances now works.
</p></li><li><p>(MacOS X version): command line programs now build.  We're working on Aven.
</p></li><li><p>Updates to the Catalan and Spanish translations.
</p></li><li><p>xcaverot: documented environmental variables XCAVEROT_INDICATOR_RADIUS and
XCAVEROT_FONTNAME.
</p></li><li><p>cad3d: added --plt option to produce crude approximation to Compass .plt
files - should be good enough for reading into Carto.
</p></li><li><p>img library enhanced to allow Compass .plt files to be read as if they were
.3d files.
</p></li></ul><h1>Changes in 1.0.1:
</h1>
<ul><li><p>(MS Windows version): printwin: fixed sizes of cross and page alignment
ticks.
</p></li><li><p>Updates to the Portuguese and Italian translations.
</p></li></ul><h1>Changes in 1.0.0:
</h1>
<ul><li><p>Fixed --survey option supported by many programs which was broken in 0.99.
</p></li><li><p>aven: altered colours of "fixed points" and "entrances" buttons to match
the coloured blobs used to indicate them.
</p></li><li><p>(MS Windows version): aven: changed current point highlighting in the
survey tree to use a light grey background rather than bold (bold causes
the text to "wriggle" as the highlight runs up or down).
</p></li><li><p>(MS Windows version): file icons now have transparent backgrounds.
</p></li><li><p>survex: removed conversion wrapper - you should use "cavern file.svx"
instead of "survex file.svx".
</p></li><li><p>(Unix version): GCC 2.95 sometimes fails with an internal error when trying
to compile gfxcore.cc - if it does, the Makefile will now try recompiling
with a lower optimisation level.
</p></li><li><p>(Unix version): when doing an "in directory" build from source, the HTML
manual is now installed in its own subdirectory as when doing a non
"in directory" build.
</p></li><li><p>German translation now completely up-to-date.
</p></li></ul><h1>Changes in 0.99:
</h1>
<ul><li><p>Fixed bug in .3d file reading code which would incorrectly reconstruct
the survey hierarchy in rare cases.
</p></li><li><p>(MS Windows version): aven: fixed redraw problem for "N found".
</p></li><li><p>(MS Windows version): minor tweaks to .err, .pos, and .svx file icons.
</p></li><li><p>(Unix version): aven: Highlight of current station restores old background
colour correctly rather than assuming it's white.
</p></li><li><p>aven: Resolved a number of menu shortcut clashes.
</p></li><li><p>(RISC OS version): fixed automatic detection of language.
</p></li><li><p>cavern: improved error reporting from *data; better handling of some
incorrect usages of *sd and *units.
</p></li><li><p>Italian translation updated.
</p></li></ul><h1>Changes in 0.99-prerelease9:
</h1>
<ul><li><p>aven: Side Panel can now be dragged or toggled shut and then reopened
again; double-clicking on the divider now maximises the survey window rather
than the side panel.
</p></li><li><p>aven: .3d files can now be loaded using "drag and drop" from MS Windows
Explorer, and X filemanagers which support XDND (e.g. Konqueror).
</p></li><li><p>aven: fixed problems with selection handling in survey tree.
</p></li><li><p>aven: Escape cancels distance measuring line; suppress distance measuring
line during auto-rotation and animated tilting.
</p></li><li><p>aven: entrance blobs now green to distinguish them from stations matching
search.
</p></li><li><p>aven: problems with dragging scalebar fixed.
</p></li><li><p>(MS Windows version): aven: Loading file on start-up now works!
</p></li><li><p>(MS Windows version): aven: Delete now works in the search box.
</p></li><li><p>(Unix version): aven: Highlight current station in tree with grey background
(don't seem to be able to use bold like we do on MS Windows).
</p></li><li><p>cavern: Fixed handling of interleaved nosurvey data.
</p></li><li><p>cavern: Diving and cylpolar styles now take DEPTHCHANGE where they used to
take DZ.
</p></li><li><p>(MS Windows version): Installer now uses a different compression
method (bzip2) which reduces the download size by about 5% (and 
should help keep the installer small enough to fit on a 1.44M floppy).
Bzip2 is a little slower to uncompress, but not appreciably so on the
machines I've checked it on.
</p></li><li><p>(MS Windows version): Should now install without errors for a
non-admin user on MS Windows NT/2000/XP.
</p></li><li><p>(MS Windows version): Installer should now allow installation on NT 3.51.
</p></li><li><p>Updated manual (notably added documentation for interleaved data styles).
</p></li><li><p>German and Brazillian Portuguese translations updated.
</p></li></ul><h1>Changes in 0.99-prerelease8:
</h1>
<ul><li><p>aven: Ctrl + Arrow keys is now the preferred way to rotate and tilt
(easier to remember than "C"/"V" and "'"/"/").
</p></li><li><p>aven: survey pane now gets initial focus so you no longer have to
click on it before key presses are recognised.
</p></li><li><p>(MS Windows version): aven: fixed problems with some keys being
impossible to enter in search box, or not being recognised in survey
pane.
</p></li><li><p>(MS Windows version): aven: wxWindows messages files were missing.  We
now include them for languages which Survex also supports.
</p></li><li><p>(MSDOS version): caverot: Shift and/or Ctrl + Arrow keys now works.
</p></li><li><p>aven: Close button in About box is now always right in the bottom right
corner.
</p></li><li><p>Display copyright symbol rather than (C) where the current character set
allows it.
</p></li><li><p>(MSDOS version): caverot: default to 320x200 when running under
Microsoft Windows 2000 and XP as we already do on NT.
</p></li><li><p>(MSDOS version): fixed problem when running on DOS outside MS Windows.
</p></li><li><p>(MSDOS version): detect current codepage rather than assuming it's 850.
We now support codepages 437 and 850 (the common ones) - for other
codepages we fall back to using 7-bit ASCII.
</p></li><li><p>(Unix version): aven: now compiles cleanly with GCC3.0.
</p></li></ul><h1>Changes in 0.99-prerelease7:
</h1>
<ul><li><p>(MS Windows version): aven was missing from 0.99-prerelease6
(if you installed over an old version you'd have kept the old aven).
</p></li><li><p>caverot/xcaverot: Ctrl + Arrow keys is now the preferred way to
rotate and tilt (easier to remember than "C"/"V" and "'"/"/").
</p></li><li><p>xcaverot: Shift-ed movement keys now work faster as in caverot.
</p></li><li><p>cavern: fixed *calibrate depth/todepth/fromdepth/dz and *units dz to
work in data styles diving and cylpolar.
</p></li><li><p>cavern: fixed handling of malformed *data commands.
</p></li><li><p>Various documentation clarifications.
</p></li></ul><h1>Changes in 0.99-prerelease6:
</h1>
<ul><li><p>aven: fixed bogus lines caused by coordinate wrap-around; fixed
problem in repeated zoom with [ or ]; tweaked layout and auto-sizing
of left panel; station search now case insensitive; regexp search
enabled; suppressed message box when wxWindows doesn't support the
language Survex is set to use; fixed obscure crash in search
highlighting; added "rubber band" between measured stations;
Improved choice of menu short-cuts in translations.
</p></li><li><p>(MS Windows version): don't include plain text versions of docs; fixed
default action for 3d files to be "Open".
</p></li><li><p>(MSDOS version): include text docs.
</p></li><li><p>cavern: more intelligent and less verbose reporting of errors in nested
included files (inspired by GCC 3.0).
</p></li><li><p>cavern: improved reporting of syntax errors in survey data.
</p></li><li><p>print*: improved reporting of invalid scales; interpret a single
number less than one as the scale in the obvious way (so "0.001"
means "1:1000").
</p></li><li><p>print*: "--crosses" no longer prevents "--station-names" from working.
</p></li><li><p>print*: if running interactively, prompt for what elements to plot
when run so MS Windows users don't have to resort to the command line.
</p></li><li><p>Improved documentation for print.ini; Other minor documentation updates.
</p></li><li><p>(Unix version) configure auto-probe for wxWindows updated to cope
with wxWindows version 2.2.8 (still works with older versions too).
</p></li><li><p>Diving and cylpolar styles now accept dz (change in depth) rather than
requiring absolute depths and taking the difference.
</p></li></ul><h1>Changes in 0.99-prerelease5:
</h1>
<ul><li><p>aven: improved initial sizing of window; "Toggle rotation" toolbar
icon now works; handle files with only stations better; presentation
code disabled for 1.0; releasing mouse over menubar now ends drag;
don't highlight hidden stations; accelerator problems fixed; find now
works.
</p></li><li><p>(MS Windows version) aven: fixed crash on File/Open when a file was
already loaded.
</p></li><li><p>cavern: After *solve, reused points are no longer written to the .3d
file a second time.
</p></li><li><p>cavern: Warn that the undocumented extra "omit" allowed by *data is
deprecated.
</p></li><li><p>cavern: Give error if standard deviation argument to *sd isn't
positive.
</p></li><li><p>Consistent capitalisation of --help option descriptions.
</p></li></ul><h1>Changes in 0.99-prerelease4:
</h1>
<ul><li><p>Minor improvements to manual and Unix man pages.
</p></li><li><p>printps/printhpgl/printwin: --skip-blanks fixed.
</p></li><li><p>printhpgl: fixed paper size for A1 landscape (was actually A2
portrait!)
</p></li><li><p>(MSDOS version): graphics in HTML manual were corrupted (by being
packed as text).
</p></li><li><p>(RISC OS version): graphics were missing from HTML manual.
</p></li><li><p>(RISC OS version and 286 DOS version): fixed programs to report
themselves as part of "Survex" rather than "@PRETTYPACKAGE@".
</p></li><li><p>(MSDOS version): pick a default language for messages by looking at the
currently set country.
</p></li><li><p>(Unix version): Improved test for whether build needs librx - before
it was used if it was present, even if it wasn't needed.
</p></li><li><p>(Unix version): Assorted minor debian tweaks.
</p></li></ul><h1>Changes in 0.99-prerelease3:
</h1>
<ul><li><p>Documentation rearranged.  Some sections which covered the same
ground have been merged, and the documentation for each program is
now available as a man page under Unix.
</p></li><li><p>(Unix version): Fixed problem with incomplete versions being
specified in debian package dependencies.
</p></li><li><p>(Unix version): Fixed problems with not having librx on Linux (it's
now built into libc).
</p></li></ul><h1>Changes in 0.99-prerelease2:
</h1>
<ul><li><p>aven: fixed bug which caused occasional crash during mouse movement;
station identifying didn't work after a resize until the survey was
moved.
</p></li><li><p>Asking for messages in language en_GB now tries language en as it
was meant to.
</p></li><li><p>printps/printhpgl/printwin: fixed typo which made --skip-blanks get
it wrong in some rare cases.
</p></li><li><p>(Unix version): Added man pages for 3dtopos and sorterr.
</p></li><li><p>(Unix version): More minor tweaks to debian packages.
</p></li><li><p>Include images with HTML documentation; other minor documentation
changes.
</p></li></ul><h1>Changes in 0.99-prerelease1:
</h1>
<ul><li><p>Major clean-up of Survex Manual; renamed from "svxdocs" to "manual".
</p></li><li><p>Text documentation converted to HTML; BUGS and TODO merged, ZOMBIES
removed.
</p></li><li><p>Include HTML documentation overview page and manual in all versions
(was only included in MS Windows before).
</p></li><li><p>aven: added new functionality: toolbar, side panel with survey tree,
find station, measure distance between two stations, click on
station to centre.
</p></li><li><p>aven: can now create presentations consisting of a set of views with
movements between them.  Useful for using aven as a "slide show" in
a conference talk.
</p></li><li><p>aven: handles loading file from command line better.
</p></li><li><p>cavern: added error checks for "*flags" (with no arguments) and
"*flags not".
</p></li><li><p>cavern: you can now specify optional covariances to *FIX.
</p></li><li><p>cavern: parser fixed to recover from errors as intended in a few
situations where it was failing to.
</p></li><li><p>cavern: implemented covariances for diving data.
</p></li><li><p>cavern: added "cylpolar" data style - similar to diving, except the
tape is measured horizontally rather than along the slope of the leg.
</p></li><li><p>cavern: complain about *export-ing or *entrance-ing a station which
is never used.
</p></li><li><p>cavern: complain about *export after a *begin without an argument.
</p></li><li><p>cavern: use *title only if at top of survey tree, else generate
title from filename(s).
</p></li><li><p>cavern: removed dummy *lrud command which was added for tunnel but
isn't used by tunnel.
</p></li><li><p>cavern: round coordinates to nearest cm when writing .3d file.
</p></li><li><p>cavern: fixed reporting of node stats for stations fixed with error
estimates.
</p></li><li><p>cavern: no longer generate a .inf file - the .log file generated by
the --log option makes the .inf file obsolete.
</p></li><li><p>cavern: only apply special pathname handling to filenames in
*include, not those on the command line.
</p></li><li><p>cavern: *date now checks its argument.  It expects an ISO format date
(e.g. 2001.09.13) or range (e.g. 2001.09.12-2001.09.13).  For cases
where the exact date isn't know, the day and month can be omitted -
e.g. 2001.09 and 2001 are also valid.
</p></li><li><p>cavern: --new-format renamed to --chasm-format.
</p></li><li><p>print*: If restricting to a subsurvey, use that survey name for the
title of the printout.
</p></li><li><p>print*: Detect .3d files produced by extend and handle them more
appropriately (don't ask for view or bearing, and modify info box
on printout).
</p></li><li><p>print*: --skip-blanks now works on printwin/printpcl/printps;
--skip-blanks now forces --no-border.
</p></li><li><p>printps: thinner lines by default (0.1 points rather than 0.5).
</p></li><li><p>printdm: added --calibrate option to print calibration page; if
there's no calibration in the .ini file, refuse to print (apart
from calibration pages) rather than printing to the wrong scale.
</p></li><li><p>printwin: removed --output option - there is no output file.
</p></li><li><p>extend: wasn't picking start station as documented - fixed and
also enhanced to try to find an entrance with legs first.
</p></li><li><p>survex: conversion wrapper doesn't use --output unless it is actually
needed, and displays corresponding cavern command line, and (if
appropriate) file.
</p></li><li><p>cad3d: added --reduction option (from Leandro) which allows sketch
output to be scaled down (default scale is 1:500); grid in sketch
file is now visible by default; default output now goes in the
current directory. 
</p></li><li><p>cad3d/3dtopos/sorterr: delete output file if there's an error
writing to it.
</p></li><li><p>3dtopos: minor improvements to sort order.
</p></li><li><p>hto2svx, svx2hto: Removed HTO support - Survex appears to be the
only released software to ever have provided support, and an
exchange format that nobody else supports is useless.
</p></li><li><p>xcaverot: report more detailed error when .3d file can't be loaded.
</p></li><li><p>`program --version' now works even if message file can't be found.
</p></li><li><p>(Unix version): Fixed attempt to load messages from
"DEFAULTLANG.msg" if both SURVEXLANG and LANG were unset.
</p></li><li><p>Much more rigorous checking for operating system errors when reading
and writing files.
</p></li><li><p>(RISC OS version): query Territory module to find currently selected
language, and use that for messages.
</p></li><li><p>(UNIX version): man pages now have "Survex &lt;version number&gt;" on them;
fixed minor flaws in man pages.
</p></li><li><p>Distinguish between a "bad" .3d file and one which has a newer
revision of the format than we understand.
</p></li><li><p>img library can now read .pos files as if they were .3d files with
just stations in, so all programs which can read .3d files can also
now read .pos files.
</p></li><li><p>Expanded testsuite further.
</p></li><li><p>French, Brazillian Portuguese, and German translations brought
almost completely up-to-date.
</p></li><li><p>(Unix version): Lots of little improvements to debian packages
(mostly from Wookey).
</p></li></ul><h1>Changes in 0.98:
</h1>
<ul><li><p>(MS Windows version): New icons for .svx, .pos, and .err files.
Tweaked .3d icon to work better in 256 colour modes.
</p></li><li><p>Added tests for `*infer plumbs' and `*infer equates'.
</p></li></ul><h1>Changes in 0.98-prerelease6:
</h1>
<ul><li><p>printwin: fixed new bug introduced in 0.98-prerelease4 which caused
an internal error.
</p></li><li><p>printwin: exit cleanly if no printer drivers are installed.
</p></li><li><p>aven: surface surveys weren't being drawn when viewing from above
(bug introduced in recent version).
</p></li><li><p>aven/caverot/xcaverot/print*/cadgen/extend/diffpos/3dtopos: --survey
command line option once more trims specified prefix from station
names like it did in xcaverot/caverot in 0.98-prerelease4.
</p></li><li><p>sorterr: Added --replace option to sort the .err file and replace
the original with the sorted version (for use by MS Windows file
associations); cope with empty .err file.
</p></li><li><p>cavern: Added --log option to send output to a .log file.
</p></li><li><p>cavern: --quiet no longer suppresses node statistics.
</p></li><li><p>extend: give up if the .3d file is truncated or corrupted part way
through.
</p></li><li><p>(MS Windows version): sorterr.exe and 3dtopos.exe were missing;
improvements to documentation; assorted fixes and improvements to
file associations.
</p></li><li><p>print*: reduced memory usage.
</p></li><li><p>Fixed dropping of first character of survey station names when
reading old .3d files.
</p></li><li><p>(MS Windows version): aven.exe wasn't rebuilt for 0.98-prerelease -
fixed the dodgy script.
</p></li></ul><h1>Changes in 0.98-prerelease5:
</h1>
<ul><li><p>aven/print*/cadgen/extend/diffpos/3dtopos: Added --survey command
line option to restrict the operation of the command to a sub-survey
in the .3d file.
</p></li><li><p>aven: initial scaling now ignores unused fixed points (unless there
are no legs at all), and scales survey so it fits inside window.
</p></li><li><p>aven: can now load a survey with no legs, only stations.
</p></li><li><p>aven: --version now works, and --help produces more helpful output.
</p></li><li><p>cavern: fixed bug with eating first character of line after
interleaved data; corrected line numbers in some situations
involving interleaved data.
</p></li><li><p>cavern: fixed problem with points fixed with errors.
</p></li><li><p>cavern: *title without quotes now stops at a comment; *title with no
argument no longer allowed - use `*title ""' if you really mean to
set an empty title.
</p></li><li><p>Minor documentation updates.
</p></li><li><p>3dtopos: Fixed bug which resulted in station names and coordinates
getting mismatched; output now defaults to current directory.
</p></li></ul><h1>Changes in 0.98-prerelease4:
</h1>
<ul><li><p>diffpos: list added and deleted stations in sorted order; better
error reporting.
</p></li><li><p>3dtopos: removed hardcoded limit on number of stations (was 100000);
better error reporting.
</p></li><li><p>Further tweaks to charset handling - look at LC_* as well as LANG;
Check GUI codepage under MS Windows.
</p></li><li><p>cavern: Allow *copyright/*date/*instrument/*team/*title between
*begin and *export.
</p></li><li><p>cavern: Fixed typo which prevented *instrument from being recognised
as a valid command.
</p></li><li><p>cavern: removed option to produce ascii .3d files.
</p></li><li><p>cavern: on error, remove any existing .inf file for consistency with
.3d and .err files.
</p></li><li><p>cavern: interleaved nosurvey data style now works; nosurvey legs now
count as a "use" of a fixed point.
</p></li><li><p>cavern: give at most 5 warnings about use of any particular
deprecated feature.  Otherwise processing an old dataset just gives
an avalanche of warnings which buries any other warnings or errors.
</p></li><li><p>cavern: implemented `*infer equates'.
</p></li><li><p>aven: if a .3d file is truncated or corrupted part way through, aven
would previously load part of it without complaint.  Fixed to
complain and not load anything.
</p></li><li><p>printwin: fixed problem where it hung when waiting for input.
</p></li><li><p>print*: Added --output command line option to override the output
setting in the .ini file (ignored by printwin).
</p></li><li><p>.3d files now store prefixes for legs (the prefix is taken from the
"from" station of the leg);  Station names and leg prefixes in .3d
files are now stored compressed.  Despite now storing prefixes for
legs, .3d files are now typically 25%-33% smaller than before.
</p></li><li><p>xcaverot/caverot: Added --survey command line option which restricts
the view to a sub-survey in the .3d file.  e.g.:
"caverot --survey 161.dream all.3d"
</p></li><li><p>(MS Windows version): added explorer bindings for sorterr.
</p></li><li><p>cavern/xcaverot/sorterr: fixed --help output to include long options.
</p></li><li><p>Minor documentation updates.
</p></li></ul><h1>Changes in 0.98-prerelease3:
</h1>
<ul><li><p>cavern/3dtopos: cavern no longer produces .pos files - they're
mostly useful for hand plotting and are larger than the
corresponding .3d files so most of the time they slow processing and
then clutter up the disk.  A new utility 3dtopos produces a .pos
file from a .3d file, and has the added benefit that it sorts names
with numbers in numerically (i.e. 2 before 10).
</p></li><li><p>diffpos: the arguments can now be .pos or .3d files, or one of each.
</p></li><li><p>cavern: improved parsing of unquoted *include/*title strings - used
to end at the first literal space; now they end at the first BLANK
character (space, tab, and comma by default).  So the odd case of an
unquoted string with commas or tabs will require quotes to be added.
</p></li><li><p>All versions have been missing RTF, text, and PostScript versions of
the documentation in the previous 2 prereleases.
</p></li><li><p>cavern: Fixed articulation code wasn't quite.
</p></li><li><p>cavern: an empty label was being added to the .3d file for a station
fixed with standard deviations.  Such labels are also now ignored by
img on read-in.
</p></li></ul><h1>Changes in 0.98-prerelease2:
</h1>
<ul><li><p>(MS Windows version): Fixed "Open" on a .3d file to open in aven
rather than converting to a DXF.  "Convert to DXF" now appears as a
separate menu item.
</p></li><li><p>cavern: Fixed bogus errors about matrix not being positive definite.
</p></li><li><p>cavern: Fixed bug in articulation point code which could result in
a traverse "exploding" in certain situations (introduced in 0.95).
</p></li><li><p>cavern: Check for chunks of survey not connected to a fixed point is
now done earlier on (which simplifies quite a bit of the network
code).
</p></li><li><p>xcaverot: Disabled "legs" and "surface" buttons in --pda mode - they
make the button bar too wide.
</p></li></ul><h1>Changes in 0.98-prerelease1:
</h1>
<ul><li><p>Covariance matrices are symmetric - now only store 6 of the 9 entries.
Typically uses 10% less memory and is 15% faster.
</p></li><li><p>caverot: adjust to speed of machine/size of survey on initial draw,
rather than on first action from user.
</p></li><li><p>(MS Windows version): now handle oe-ligatures.
</p></li><li><p>(Unix version): discover character set by looking at $LANG.
</p></li><li><p>(MS Windows version): discover character set from Windows.
</p></li><li><p>Transliterate accented characters that can't be represented in the
current character set.
</p></li><li><p>Added support for Latin9 (iso-8859-15) character set.
</p></li><li><p>printps/printpcl/printwin: Improved handling of accents on printouts.
</p></li><li><p>aven: added optional grid; dashed surface survey now the default;
Indicators moved to submenu of View menu.
</p></li><li><p>aven: reporting errors in a message box wasn't working (wxWindows
bug).
</p></li><li><p>cavern: fixed *entrance - it was trying to insist its argument was a
survey, not a station.

there are no errors or warnings.
</p></li></ul><h1>Changes in 0.97-prerelease6:
</h1>
<ul><li><p>(MS Windows version): aven: if there are problems opening the
message file, report them in a message box rather than printing text
which the user will never see.
</p></li><li><p>cavern: invalid data lines weren't being counted, so you'd get
incorrect line numbers reported for further errors and warnings.
</p></li><li><p>cavern: Added a SPLAY flag for indicating splay shots in chambers
and large passages.
</p></li><li><p>extend: ignore surface legs and splay legs; preserve duplicate flag
on extended legs.
</p></li><li><p>print*: if surface data isn't being plotted, ignore surface survey
stations too, and select page layout based on underground data only.
</p></li><li><p>(MS Windows version): get default language from Windows.

<ul><li><p>survex: conversion wrapper now only creates __svxtmp.svx file if it
has to - simple cases (such as "survex example.svx") don't need one;
also always print warning that user should be using cavern instead.
</p></li><li><p>Minor updates to documentation.
</p></li><li><p>Survey stations names are no longer displayed with a leading '\' -
this doesn't make sense now that root is deprecated, and didn't make
much sense before to be honest.
</p></li><li><p>cavern: *fix with two standard deviations (horizontal and vertical)
was being rejected - fixed.
</p></li><li><p>cavern: Fixed bug with station "\" appearing in the .err file for

short-form for `--surface'.
</p></li><li><p>Added test of *solve command.
</p></li><li><p>cavern: Added commands *date, *team, *instrument, *copyright -
currently these are ignored, but they provide a place to put data
when importing/exporting, and will be processed in future versions.
</p></li><li><p>(MS Windows version): aven updated to same codebase as Unix version.
</p></li></ul><h1>Changes in 0.97-prerelease4:

English; speed improvements; redesign of indicators; rescale by
dragging scalebar; allow surface legs to be hidden (they are by
default); now defaults to plan view; depth bar labelling improved;
added caverot-like handling of flat surveys (so output from extend

</p></li><li><p>cavern: Complain if the same name is used for a survey and a station.
</p></li><li><p>cavern: Added --warnings-are-errors command line option.

than toggling plan/elevation.

"R" (Reverse Rotation) now only affects the auto-rotation - it used
to affect "C", "V", "/", and "'".

error estimates; added test cases for this.
</p></li><li><p>testsuite: Enhanced many existing tests to check for warnings.
</p></li><li><p>Fixed to build on Solaris with Sun's compiler.
</p></li><li><p>Minor corrections to documentation and man pages.
</p></li><li><p>cavern: report *export errors at the file and line where the *begin
for the survey involved was as that's much more useful.
</p></li><li><p>cavern: allow "-" in station names by default.
</p></li></ul><h1>Changes in 0.97-prerelease3:

Depth bar tidied up; Orientation menu changes; Menu accelerators
fixed; Status bar disabled (various continuing problems and it
doesn't really convey much useful info anyway); About box fixes;
Fixed crashes on mouse actions when no survey loaded; Improved
labelling of scale bar and indicators.
</p></li><li><p>Created Swiss German and "German German" sub-versions of German
translation.
</p></li><li><p>(DOS version): caverot: fixed slight underallocation of memory which
probably caused the bug Brian Clipstone reported.
</p></li><li><p>cavern: Improved reporting of missing *export-s; added 2 more
*export tests.
</p></li><li><p>No longer trap SIGINT (Ctrl-C) or SIGTERM (Ctrl-\ on Unix) as we
can't do anything useful.
</p></li><li><p>Removed support for really old language names ("fren", "germ",
"ital", etc) - use "fr", "de", "it", etc instead.
</p></li><li><p>(RISC OS version): support a few extra accents in messages.
</p></li><li><p>"Syntax" in command-line help messages now translated.
</p></li></ul><h1>Changes in 0.97-prerelease2:

<ul><li><p>cad3d: Fixed output from `--help'; -e, -D, -S short options now work;
fixed infinite loop bug.
</p></li><li><p>(Unix version): aven: leaving "about" box no longer causes segfault;
toggle status bar now works; N/S/E/W selects view rather than moving
cave; window close now works; now have ticks on appropriate menu
items; fixed problems with rendering (some legs missing!); 3d file
specified on command line now loaded; fixed occasional hangs; fixed
terrible slowness during rotation; implemented indicators; various
other bugs fixed.
</p></li><li><p>Updated translations: pt de it (and fr partially)
</p></li><li><p>Added tests for most commands and various other cases.
</p></li><li><p>cavern: fixed *case (correct args are PRESERVE/TOUPPER/TOLOWER) and
upper/lower were swapped.
</p></li><li><p>Documentation brought more up-to-date.
</p></li><li><p>caverot/xcaverot: fix missing end of list marker for surface data
which typically resulted in a few extra bogus surface legs appearing.
</p></li><li><p>printer drivers: fixed .ini file reading routine (bug introduced in
0.97-prerelease 1).
</p></li><li><p>printps: postscript file meta information now includes the date of
creation, and also the name of the user running printps (Unix only).

<ul><li><p>extend: fixed bug which resulted in bogus output (added regression test);
produce binary rather than ASCII .3d output.
</p></li><li><p>cavern: don't report error stats for articulating traverses.
</p></li><li><p>(UNIX version): `make uninstall' now removes the HTML documentation.
</p></li><li><p>(UNIX version): printer drivers: Look for /etc/survex/print.ini rather
than &lt;prefix&gt;/share/survex/myprint.ini
</p></li><li><p>cavern: added warning that use of ROOT character ('\' by default) is
deprecated; updated documentation to mention this.
</p></li><li><p>cavern: added *export command to allow scope of station names to be
limited.  If *export is never used, behaviour is as before.
</p></li><li><p>cavern: added *flags command to allow surface surveys and duplicate
surveys (to be ignored when calculating the total survey length) to be
indicated.
</p></li><li><p>new version of 3d file format which can store flags and is slightly more
compact.  NB New programs can load old .3d files, but old programs can't
load new .3d files.
</p></li><li><p>caverot/xcaverot: allow surface legs to be hidden (they are by default)
</p></li><li><p>cavern: compass can be omitted on legs in diving data to indicate a plumbed
leg.  In this case the tape and depth gauge readings are combined to give
the length of the leg.
</p></li><li><p>cavern: *begin/*prefix reentry warning now gives the original location as
a separate warning so smart editors will allow you to click on it to jump
to that file and line.
</p></li><li><p>printer drivers: put "http://www.survex.com/" on printouts in case someone
who gets a printout wants to know more about Survex.
</p></li><li><p>cavern: added easting, northing, altitude added as prefered aliases for
dx, dy, dz.
</p></li><li><p>cavern: bug fix: "*prefix \" or "*begin \" would cause an internal error.
</p></li><li><p>xcaverot: "load" button now works; bearing always shown in range 0-360;
/ and ' now tilt cave; `u' and `d' now switch to view from above/below;
shift-ed keys now work; `o' now turns off non-overlapping labels;
`ctrl-L' toggles display of survey legs.
</p></li><li><p>caverot: n/s/e/w/u/d now work as in xcaverot - the previous functions they
had weren't actually useful; if memory is really tight, disable
non-overlapping labels rather than dying with an error.
</p></li><li><p>prefer balanced quotes (`...') to unbalanced ('...') in messages.
</p></li><li><p>cavern: file reading errors now treated as fatal; unattached survey error
now fatal.
</p></li><li><p>survex: syntax errors in command line arguments now fatal.
</p></li><li><p>cavern: if there are errors, don't produce output files.
</p></li><li><p>cavern: bug fix: trying to report certain errors in really long lines could
cause an internal error.
</p></li><li><p>3dtodxf: renamed to cad3d since it can now produce DXF or sketch format.
</p></li><li><p>aven: rewritten to use wxwindows (under Unix only so far).
</p></li><li><p>printwin: new native Microsoft Windows printer driver.
</p></li><li><p>(MS Windows version): new installation wizard.
</p></li><li><p>Use double precision floating point to pass numbers to/from .3d file
reading routines to avoid rounding problems.
</p></li><li><p>cavern: change of terminology - use "reading" instead of "datum",
since datum more usually means a map datum in surveying.
</p></li></ul><h1>Changes in 0.96:
</h1>
<ul><li><p>(MSDOS and MS Windows versions): fixed bug in message file handling
introduced in 0.96-prerelease 1 - symptoms: messages incorrectly looked
for in current directory, or just printing "???" and exiting.
</p></li><li><p>cavern: attempting to *include a non-existent file used to complain:
"In file included from example.svx:31:" / "cavern: Couldn't open data file
'bad.svx'" - now complain "example.svx:31: Couldn't open data file
'bad.svx'".
</p></li><li><p>xcaverot: cursor keys now move the 3D centre of rotation rather than just
the position of the survey in the window.
</p></li></ul><h1>Changes in 0.96-prerelease4:
</h1>
<ul><li><p>cavern (RISC OS version): "is this a directory" test would never say
"yes".
</p></li><li><p>caverot: (MSDOS version) cursor keys and delete had stopped working (due
to changes in allegro graphics library) - fixed.
</p></li><li><p>xcaverot: Zoom in and out with keyboard now behaves exactly like clicking
on buttons; Removed unused "select" button; Fixed significant memory leak.
</p></li><li><p>aven: (MS Windows version) Mark Shinwell has written a Microsoft Windows
version of aven, which is better in almost every way than the directx
version of caverot (and we're working to fix the few shortfalls), so we've
shelved directx caverot and are now including aven instead with the MS
Windows version.
</p></li></ul><h1>Changes in 0.96-prerelease3:

internationalised.

</h1>
<ul><li><p>xcaverot: Improved responsiveness; can now load multiple .3d files from
command line; set defaults (press DELETE) now defaults scale that which
fits the whole survey on the screen.
</p></li><li><p>cavern: Fixed bug in DOS and Windows versions with handling of paths
containing a mixture of "/" and "\".

the minimum survex version required to process it
</p></li><li><p>print*: now search multiple print.ini files so you can override settings

~/.survex/print.ini (unix only), &lt;prefix&gt;/share/survex/myprint.ini,
&lt;prefix&gt;/share/survex/print.ini

</p></li><li><p>"printps -b" now reports "option requires an argument" (used to segfault)
</p></li><li><p>Updated printer driver command line options in manual
</p></li><li><p>caverot: Fixed shift key to accelerate movements in allegro version
</p></li><li><p>cavern: Disabled articulation point code (for now - there's a bug)
</p></li><li><p>cavern: If a datafile isn't found, now try a lowercase version
before giving up (so on Unix you can now process a DOS dataset by
unpacking with "unzip -L" to force filenames of unpacked files to
lower case)
</p></li><li><p>diffpos: Fixed a couple of bugs; also now exits with status 1 if
differences were reported
</p></li><li><p>Added some tests for cavern and diffpos - more to follow
</p></li><li><p>cavern: Covariance code now working and enabled by default
</p></li><li><p>cavern: When equating two existing stations we need to replace the
pos of one with the pos of the other.  We used to look down the
whole station list, now we just look at neighbouring nodes
(noticeable time saving for large networks with many equates)
</p></li><li><p>cavern: Renamed truncate function in commands.c to avoid clash with
library truncate function on FreeBSD
</p></li><li><p>cavern: Warn that *prefix and *default are deprecated
</p></li><li><p>Fixed obscure problems when configure is rerun with a different prefix
</p></li><li><p>If the environmental variable SURVEXLANG isn't set, LANG is now
check before resorting to the default.  LANG is a standard way to
specify the language for GNU applications - SURVEXLANG is still
useful as a way to specify an alternate language if Survex doesn't
support your prefered language.
</p></li><li><p>Cured superfluous copy of svxdocs in doc/svxdocs in source distribution
</p></li><li><p>RISC OS and BorlandC builds now track copyright message and version
number automatically
</p></li><li><p>If LANG is set to "en_US", treat it as if it were "en-us"
</p></li><li><p>xcaverot: Merged in changes from John Pybus and Mark Shinwell
</p></li><li><p>cavern: *solve followed by some entirely unconnected survey now
caught cleanly (used to hit an assert)
</p></li><li><p>cavern: Corrected component and loop counts when there's hanging
survey around

</p></li></ul><h1>Changes in 0.90:
</h1>
<ul><li><p>caverot: MSDOS Allegro mode-picker now reappears if an invalid mode

</p></li><li><p>fixed problem with US English messages
</p></li><li><p>text files in DOS/Win32 zips now have ".txt" extension and DOS
end-of-lines
</p></li><li><p>3dtodxf: Leandro Dybal Bertoni has made major improvements to
DXF output
</p></li><li><p>caverot: Right and Middle mouse button functions were swapped under
RISC OS
</p></li><li><p>caverot: BorlandC (pre-386) version wasn't erasing screen between redraws
</p></li><li><p>HTML version of documentation now has a hyperlinked table of
contents
</p></li></ul><h1>Changes in 0.90 beta3:
</h1>
<ul><li><p>cavern: output files now go in current directory rather than the
same directory where the first .svx file is found.  You can set a
different directory using the "--output" command line option, which
can point to a directory or a file.
</p></li><li><p>cavern: "*truncate off" rather than "*truncate 0"
</p></li><li><p>survex: added wrapper to convert survex invocation into cavern invocation
</p></li><li><p>hto filters moved into separate subdirectory of source distribution
</p></li><li><p>cavern: fixed bug which included stations with 4 or more connections
in the .3d file several times
</p></li><li><p>added "miniam.pl" which generates makefiles for BorlandC and RISC OS
</p></li><li><p>printdm/printpcl: weren't showing text - problem with new format
font file

</h1>
<ul><li><p>Added ChangeLog
</p></li><li><p>DOS binary distribution now includes files: BUGS NEWS TODO ChangeLog
</p></li><li><p>Cross-compiler build for DOS now has debugging information stripped
from .exe files once more, so they are rather smaller
</p></li><li><p>Sources now include configure.in for those wanting to do major development
work
</p></li><li><p>Unix versions now build use GNU autoconf - to build just unpack, run
"./configure" then "make"
</p></li><li><p>Messages file now represents accents like in HTML (e.g. &amp;eacute;
for é)
</p></li><li><p>caverot: fixed up standard DOS (allegro) version to work much
better.  In particular, it will now try to choose a video mode for
itself (use --mode-picker at the end of the command line to get the
mode picker), and keyboard and mouse initialisation problems are
cured
</p></li><li><p>survex: You can now use DOS or UNIX style filenames (/ or \ for
directory separator) on any platform and they will be translated to
the native format for your OS.  This makes datasets much more
portable.

names if set
</p></li><li><p>Removed artificial limit on survey station name length (was 12

</h1>
<ul><li><p>Language support for Catalan, Spanish, and Italian added

DOS version
</p></li><li><p>Printer Drivers: INI file used instead of multiple configuration files.
</p></li><li><p>Printer Drivers: Defaults set-able for all print settings
</p></li><li><p>Printer Drivers: Option to print tilted plots
</p></li><li><p>printhpgl: now has origin in centre of page option (and is default)
</p></li><li><p>printdm/printpcl: Printer font made ISO-8859-1 compatible
</p></li><li><p>Printer Drivers: Dotted borders to facilitate cutting to size with scissors

</p></li><li><p>survex: *calibrate, *data, and *units enhanced in a backwards
compatible way
</p></li><li><p>survex: survey network is now split at articulation points
(faster/less memory)
</p></li><li><p>survex: Omitted clino readings give a vertical sd of tape/sqrt(10)
</p></li><li><p>survex: filenames with spaces are now supported - just put them in
quotes ("")
