<h1>Changes in 1.2.6 <small>(2012-02-23)</small>:
<ul><li><p>(Mac OS X version): Fix so that cavern finds its messages when run by aven.
</p></li><li><p>(Microsoft Windows version): Include JPEG images for aven in the installer
package (ticket#35).
</p></li><li><p>cavern: If we have a reference to a station in a non-existent survey, give a
helpful error rather than saying the station hasn't been exported from the
survey.  (Bug reported by Martin Green via email)
</p></li><li><p>aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
</p></li><li><p>findentrances: Add findentrances utility from Olaf Kahler which produces a
.gpx file with waypoints for entrances.  This needs libproj so is disabled
by default for this release - to enable it install the development stuff for
libproj and build survex with:
make FINDENTRANCES=findentrances
make install FINDENTRANCES=findentrances
</p></li><li><p>dump3d: Add support for showing img_ERROR_INFO items.
</p></li><li><p>doc/3dformat.htm: Merge in some improvements from Mike McCombe.
</p></li><li><p>Incorporate a French translation from launchpad I'd previously copied the
English version of by mistake.  Attempt to correct mistranslation of "survey
</p></li></ul><h1>Changes in 1.2.5 <small>(2012-01-03)</small>:
<ul><li><p>The survey tree in the left panel is now in sorted order once more.
</p></li><li><p>No longer fails with an assertion if used for a long time (we were leaking
an OpenGL list each time one had to be regenerated).
</p></li><li><p>Now builds with newer FFmpeg library.
</p></li><li><p>Draw measuring line in front of the indicators rather than behind them.
</p></li><li><p>Loading a new file (or reloading the current one) no longer invalidates
the OpenGL lists for the compass and clino, so will be a fraction faster.
<li><p>Improve handling of attempts to look up translated messages before the
message subsystem is fully initialised (which only happens if there's an
error early on).
</p></li><li><p>Improve the survex(7) man page text, and fix it to be marked as section 7 in
the man page source as well as in the filename.
</p></li></ul><h1>Changes in 1.2.4 <small>(2012-01-01)</small>:
<ul><li><p>A change in 1.2.3 meant that aven tried to use OpenGL before it was
initialised, which doesn't cause problems in some machines, but causes aven
to abort on others.  This is now fixed, and there's a check in place to
help avoid similar issues in future. (ticket#34)
</p></li><li><p>Always use metres or feet for the depth colour key, and chose a consistent
precision by looking at the depth range. (ticket#30)
</p></li><li><p>Show the depth units below the colour bar rather than after every value.
</p></li><li><p>When zooming way in, stay in metres rather than switching to cm.
</p></li><li><p>On the scale bar, say “1 mile” rather than “1 miles”.
<li><p>Translation updates for Catalan, French and Slovak.
</p></li></ul><h1>Changes in 1.2.3 <small>(2011-12-31)</small>:
<ul><li><p>Fix to build with wxWidgets 2.9.2.
</p></li><li><p>(Mac OS X version):
<ul><li><p>Processing .svx files from aven now works.
</p></li><li><p>Remove spurious blank lines from the licence text in "Get Info".
</p></li><li><p>Don't create the help menu at all, as it is empty (because the "About"
entry goes elsewhere) and sometimes seems to appear in the UI.
</p></li><li><p>INSTALL.OSX: Update to reflect current status.
<ul><li><p>Fix Y coordinates of surface surveys on printouts.  (Closes #32)
</p></li><li><p>Improvements to text plotted on the survey pane:
- Support plotting Unicode character points > 256 by lazily loading the
data for them from the font file and plotting them with a direct call to
glBitmap(), which is slower but doesn't require a display list per
- Adjust the spacing from fixed width to putting a one pixel gap either
side of each one character (so two between adjacent glyphs).  Mostly this
reduces the horizontal width, but it adds a pixel for characters like "m"
and two in a few cases.
- Fix .pixelfont file generation to correctly handle characters wider than
8 pixels.
</p></li><li><p>Fix expected cross shape so don't always reject using texture mapping to
draw crosses.
</p></li><li><p>As we read a survey file, eliminate tubes consisting of zero XSECTs as well
as those consisting of just one.  Previously we would trip over the empty
tube later.  Such tubes can for example be created by extend if a splay shot
is the start or end of a tube.
</p></li><li><p>Make the green colour used for entrances in the survey tree the same
(slightly darker than before) green used for the entrance blobs.
</p></li><li><p>Report the version of the library we're actually running with if built
against wx >= 2.9.2.  Make it clear that the version reported is the
version *built* with for wx < 2.9.2.
<ul><li><p>Copy the end markers for passage tubes.
</p></li><li><p>Preserve left and right data for tubes (previously they were set to -1.0
which means "no info").
<li><p>img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
was no longer used - it certainly is!
</p></li><li><p>Use curly double quotes instead of "`" and "'" to quote filenames, etc in
messages, and curly single right quote instead of straight ASCII apostrophe.
Fall back to using straight ASCII versions if we can't represent them in the
current character set.
</p></li><li><p>Translation updates for Catalan, French, Slovak and Spanish.
</p></li><li><p>Test suite:
<ul><li><p>Add test coverage for interleaved diving data.
</p></li><li><p>Add testcase for diving data with topofil-style distance.
</p></li></ul></p></li></ul><h1>Changes in 1.2.2 <small>(2011-10-06)</small>:
<ul><li><p>Replace the textured-mapped font drawing with an approach based on
glBitmap.  This doesn't suffer from the character alignment issues which
the textured-mapped fonts had, and is actually significantly faster on some
machines.  The current font used is (mostly) fixed-width, but this isn't an
inherent limitation - it was just the easiest font data to convert to a
usable format.
</p></li><li><p>Fix assertion failure due to rounding differences on loading certain .3d
files.  (ticket#26)
</p></li><li><p>Fix assertion failure when turning on 3D passages if they stick out higher
or lower than any station.  (ticket#29)
</p></li><li><p>Fix grid not to disappear when blobs are turned on and blobs are drawn
using lines.
</p></li><li><p>If a degree sign isn't available in the character set in use, transliterate
it to 'dg' rather than skipping it.
</p></li><li><p>Fix message which should have been a degree sign but got lost in the format
change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
that bearings in the status bar now have a degree sign after them if they
are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
</p></li><li><p>Fix print dialog to calculate the scale required for "One page" right
before it calculates how many pages are required, so we don't end up
something other than 1x1 being shown when the user changes settings.
</p></li><li><p>Update the calculations for picking a scale and for deciding how many
pages are needed to take into account the change in info box height made
in 1.2.1.
</p></li></ul></p></li></ul><h1>Changes in 1.2.1 <small>(2011-10-04)</small>:
<ul><li><p>Translation updates for US English.
<ul><li><p>Rename the "depth bar" to "colour key" in documentation, menus, etc since
it now shows colours for dates and errors as well as depths.
</p></li><li><p>In the colour key for "colour by date", change "No info" to "Undated".
</p></li><li><p>Remove the dark grey background from the colour key and just put a single
pixel black border around the colours.  This is more in keeping with the
other controls, and means the colours are now on a black background so more
visually similar to the survey legs.
</p></li><li><p>Move the colour key's "Undated"/"Not in loop" entry down a little to
improve the appearance.  Make each section a pixel taller.
</p></li><li><p>Allow "Colour by X" to be selected even if there's no data for X or only a
single value of X used (the colour key is much smaller in these cases, and
does still provide some useful information).
</p></li><li><p>Fix incorrect calculation of depth colouring for survey legs which straddle
a depth band boundary.
</p></li><li><p>The scale bar, compass, clino, and colour key now all have right click
menus which allow related actions to be performed (especially handy in
full-screen mode).
</p></li><li><p>Improve the font used on the survey pane - it now contains the '-'
character (so the clino now shows negative angles as negative, and dates
in the colour key are now hyphenated).  Also the spacing and alignment
are a little better, though still not perfect.
</p></li><li><p>PLT file export now handles spaces and control characters in station names
by escaping them with '%' as in URLs.
</p></li><li><p>Pressing "Enter" on a station in the tree control now centres the view on
that station.
</p></li><li><p>The scale bar is now cached in an OpenGL display list since it often gets
redrawn exactly the same - for example, when rotating, panning, etc.
</p></li><li><p>Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
then forces a refresh of the survey pane.  This is intended as a debugging
aid - if pressing F5 changes the display at all then there's a missing case
where a list should have been invalidated (please report if you find such
a case as it is a bug).
</p></li><li><p>We now automatically track which OpenGL display lists need to be
invalidated on window width or height changes.
</p></li><li><p>Increase scale bar maximum width from 65% of the window width to 75% as it
was in 1.0.x (except that if that would overlap the clino we now reduce
that proportion down until it reaches 50%).  Make the limit of zooming in
the same as in 1.0.x.  (ticket#23)
</p></li><li><p>(Linux version): Previously wxGTK didn't really handle showing a dialog if
the application was fullscreen (the dialog got opened under the main
window!)  To work around this, aven would switch out of full screen mode
temporarily while showing a dialog.  This case works properly with recent
wxGTK, so disable our workaround with versions we know work.  Also, apply
the workaround only for wxGTK, not everywhere except on Microsoft Windows
as there's no reason to think we need it for other platforms.
</p></li><li><p>Grey out the "View North" action when we're already viewing North, and
similarly for other compass points.
</p></li><li><p>(Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
info in the "About" dialog.
</p></li><li><p>Fix to set the correct filename on the root of the survey tree - previously
the filename of the previous file loaded was used!
</p></li><li><p>The movie export code now works with newer versions of the FFmpeg libraries
as well as still working with older versions.
</p></li><li><p>Fix mixed up messages - the print dialog now says "View" on the left
subgroup of controls rather than some unrelated message.
</p></li><li><p>On printouts, combine the "Plan View"/"Elevation" info box field with the
field which gives the bearing and reduce the height on the info box by the
removed field, so it's now 3cm for plans and elevations, as for extended
elevations.  Report the tilt angle for tilted elevations which it seems has
been missing for ages (it's not in recent 1.0.x either).
</p></li><li><p>Tweak the exact positioning of informational text on printouts to look
nicer and make better use of the available space.
</p></li><li><p>Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
</p></li><li><p>Make the sign of the tilt angle for printouts consistent with the sign
shown by the "clino" in the survey pane.
</p></li><li><p>In the "Print" dialog, when in plan view disable the "Plan view" button,
and similarly for the "Elevation" button.
</p></li><li><p>(Microsoft Windows version): Sort out appearance of custom cursors.
</p></li><li><p>If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
</p></li><li><p>(Mac OS X version): F11 puts aven into full screen mode, but apparently
you can't get out again easily, so add code to explicitly check for F11
being pressed and toggle full screen.
<li><p>(Linux version): Fix the RPM .spec file for where man pages now get installed
and package aven.svg and the vim support files.  (Fixes from James Begley)
</p></li><li><p>"make check" now performs several checks on the translation files.
</p></li><li><p>More messages are now available to be translated.
</p></li><li><p>cavern: Fix reporting of ranges of survey coordinates, which was broken by
the message handling changes in 1.2.0.
</p></li><li><p>Fix warning when compiling with GCC.
</p></li><li><p>INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
sudo for installing on Unix.
</p></li><li><p>In the manual, replace the instructions for building from source with a
pointer to the clearer instructions in INSTALL.
</p></li><li><p>In the manual, make it clear that installing with administrator rights
also applies to newer platforms than XP.
</p></li><li><p>doc/TODO.htm: Update.
</p></li></ul><h1>Changes in 1.2.0 <small>(2011-09-20)</small>:
<ul><li><p>Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
</p></li><li><p>tests/smoke.tst: aven no longer requires an X display for --help or
--version, so replace skip of this check with a check that this remains the
</p></li><li><p>We now use the standard .po and .pot file formats for storing translations
(rather than the Survex-specific messages.txt format), and then translate
these into Survex's .msg format.
</p></li><li><p>(Unix version): Move survex man page to section 7 (since it isn't documenting
an actual command).
</p></li><li><p>(Unix version): Write each generated man page to a temporary file, then
atomically rename, to avoid leaving an empty or partial man page behind if
docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
recurrence of that).
</p></li><li><p>(Unix version): Default to installing docs into /usr/share/doc/survex rather
than /usr/doc/survex.
<ul><li><p>Fix handling of accented characters in the survey pane.
</p></li><li><p>Aven icon redrawn in SVG format - it's now a vector image which looks
nicer at larger sizes.
</p></li><li><p>Explicitly request double-buffering, which seems to be needed for systems
with GLX >= 1.3.
</p></li><li><p>Fix crash while trying to load certain .3d files.
</p></li><li><p>Movie export code updated to work with more recent versions of FFmpeg.
Currently this is disabled in Microsoft Windows builds, pending getting the
required libraries set up for building releases.
</p></li><li><p>Reporting of errors during movie export improved.
</p></li><li><p>Force playback speed to "x1" during movie export.
</p></li><li><p>Use stock IDs for buttons where appropriate - such buttons may now be
rendered with icons on some platforms.
</p></li><li><p>If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
</p></li><li><p>(Unix version): Remove special handling for toggling "full screen" on wxGTK
as it's no longer required with modern versions.
</p></li><li><p>Don't redraw the survey on every mouse movement in the survey pane unless
the measuring line is (or just was) active.  (ticket #17)
<ul><li><p>Drop "non-fatal" from the report of how many errors there were at the end
of the run - it just confuses users - we won't even get here if there's a
fatal error!
</p></li><li><p>Add --3d-version option to allow the user to specify the version of the 3d
format to output.  (ticket#21)
<li><p>img library:
<ul><li><p>Make the highest and lowest valid values for img_output_version available
<li><p>(Mac OS X version): Fix script to check where the temporary
volume actually gets mounted.  Fix URL for downloading wxWidgets.
</p></li></ul><h1>Changes in 1.1.16 <small>(2011-05-16)</small>:
<ul><li><p>Translation updates for German, Spanish, Italian, Portuguese, Brazilian
Portuguese, and US English.
</p></li><li><p>Use horizontal ellipses character rather than '...' and right arrow character
rather than '->' where these characters are available.
</p></li><li><p>(Unix version): Link with -lGL, if it exists, to support linking with gold or
GNU ld --as-needed (Debian bug #615781).
<ul><li><p>Fix code typo for IMG_API_VERSION == 0 case.
</p></li><li><p>Fix code typo in code used when IMG_HOSTED isn't defined.
<li><p>doc/TODO.htm: Remove entries which have now been done.
</p></li><li><p>(Microsoft Windows version): aven: We now include all the available
translations for messages from wxWidgets, which means that standard widgets
will appear translated where available even if Survex messages aren't
</p></li></ul><h1>Changes in 1.1.15 <small>(2010-10-15)</small>:
<ul><li><p>In the cavern log window, change the "Rerun" button to "Reprocess" to
follow terminology in manual and elsewhere.  Fixes ticket#15.
</p></li><li><p>When displaying output from cavern, don't update the window after every
line, but only when we don't have data from cavern pending.  Hopefully
addresses ticket#12.
</p></li><li><p>If we aren't using GL_POINTS for blobs, draw them using a series of
abutting lines rather than with gluDisk which is faster and gives a
consistent shape.
</p></li><li><p>Check whether blobs and crosses actually render correctly as points/point
sprites, and if they don't, fall back to drawing them with lines.  The
best method is cached on disk, and rechecked automatically if the graphics
hardware is changed or the drivers upgraded.
</p></li><li><p>Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
though, so we still enable USE_FNT by default).
</p></li><li><p>Don't offer "All files" wildcard in presentation save dialog.
</p></li><li><p>(Microsoft Windows): Handle filenames with non-Latin1 characters in in
more places.
</p></li><li><p>(Microsoft Windows): Quote filenames with spaces and metacharacters in
when running cavern from aven.  Fixes ticket#11.
<li><p>editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
</p></li><li><p>diffpos: Handle files with duplicate labels in better - extend generates
duplicate labels when it breaks a loop.
</p></li><li><p>Enable eswap-break testcase now that diffpos handles duplicate station names.
</p></li><li><p>New v7 of .3d format which stores survey dates as number of days since
January 1st 1900, so we now support dates from 1900-2078 (rather than
1970-2037) with a smaller file size.  The img API is now versioned - you
can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
gives the survey dates in days in days1 and days2 instead of as time_t
values in date1 and date2.  Fixes ticket#14.
</p></li><li><p>Consistently use rather than - the
former has been the canonical name for some time, with just
redirecting to it.
</p></li><li><p>(Unix version): Use unlocked file I/O if available, which can be much faster
in some cases (we don't need the locking as we don't do multithreaded file
</p></li><li><p>(Mac version): Fix compilation failure due to clash with Point in Mac OS X
</p></li><li><p>(Mac version): now works again.
</p></li><li><p>Most tests weren't actually running any testcases (looks like a sh
portability issue).  This is now fixed, and fortunately all tests still pass.
</p></li><li><p>Include the extra .isl translation files for Innosetup in the source archive.
</p></li></ul><h1>Changes in 1.1.14 <small>(2010-07-26)</small>:
<ul><li><p>Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
<ul><li><p>After processing survey data, if there were warnings or errors, add a
"Rerun" button to allow easy reprocessing after fixing problems.  If there
were only warnings, also add an "OK" button to allow moving on to viewing
the processed survey data (fixes ticket#13).
</p></li><li><p>Optimise updating of the cavern log window (hopefully fixes ticket#12).
</p></li><li><p>Fix links in cavern log window to link from exactly '<file>:<line>' (and
not the ': ' after), and to make the title for the terminal the
warning/error message.  Avoid false positives by checking that '<line>' is
a number.
</p></li><li><p>Don't double escape the contents of href and target in links in the cavern
log window.
</p></li><li><p>Improve handling of the splitter window, fixing behavioural glitches in
various cases.
</p></li><li><p>Highlight stations matching any current search when a file is loaded.
</p></li><li><p>(Mac version): Fix build issue due to Mac OS X polluting the global
namespace with its own "Point" class.
</p></li><li><p>(Unix version): The Gnome print dialog has its own preview window so
suppress ours if using the Gnome one.
</p></li><li><p>(Unix version): Link aven with -lGLU which SuSE Linux needs.
</p></li><li><p>(Microsoft Windows version): Fix handling of a double-click on the survey
tree when built with wxWidgets >= 2.8.11.
<li><p>cavern: Report relevant file and line number for three warnings which didn't
give them before.
</p></li><li><p>(Unix and Mac versions): configure: Update the wx-config probing code -
wxmac-config etc aren't present with newer wxWidgets versions so there's no
point looking for them now.
</p></li><li><p>(Mac version): This script builds a diskimage with Survex in
for easy installation.  Update it to work with the latest Survex versions
(use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
private wxWidgets, use 2.8.11 not 2.7.0-1).
<ul><li><p>Correctly capitalise "GTK".
</p></li><li><p>Note that on Linux we only regularly test builds with the GTK+ version
(change taken from 1.0).
<li><p>Fixed the cad3d man page, which was an empty file in 1.1.13.
</p></li></ul><h1>Changes in 1.1.13 <small>(2010-06-16)</small>:
<ul><li><p>Say "wxWidgets" instead of "wxWindows" consistently.
</p></li><li><p>img.c: Fix small memory leak (filename_opened member).
</p></li><li><p>cad3d, aven: Fix export to SVG when a label contains a '%' character.
<ul><li><p>wxWidgets 2.6.0 or newer is now required.
</p></li><li><p>A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
work but hasn't been tested recently (all packaged versions of wxWidgets
seem to be Unicode now).
</p></li><li><p>Fix potential uses of uninitialised variables which may have been causing
occasional glitches when loading a file on start-up.
</p></li><li><p>Improvements to the handling of the font used for plotting labels and other
text on the survey pane:
- Loading the font file is more efficient.
- Character spacing is improved.
- Default font is now anti-aliased.
</p></li><li><p>"About" dialog:
- Add "Copy" button to copy the system info to the clipboard for easier
bug reporting.
- List OpenGL extensions last, since there are usually lots of them with a
modern gfx card.
- Fix 100% CPU usage while the "About" dialog is open.
</p></li><li><p>Processing .svx files:
- Passing a .svx file on the command line now works better.
- Put the survey data log window in a splitter in the usual frame rather
than opening a separate frame for it.
- Auto-scroll the log window until we've reported a warning or error.
- Fix small memory leak.
</p></li><li><p>The presentation filename now defaults to using the basename of the
currently loaded dataset, but we always prompt before we first save with
such a name.
</p></li><li><p>Reduce memory usage when saving a screenshot.
</p></li><li><p>Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
persist the window size (and maximised or fullscreen state) between
</p></li><li><p>Fix reporting of OpenGL errors.
</p></li><li><p>Fix glitches when tilting while looking East.
</p></li><li><p>Added Portuguese and Slovak translations of wxWidgets messages.
<ul><li><p>Rationalise manual formats - replace PostScript with PDF and drop RTF.
</p></li><li><p>Drop the "alternative manual formats" self-extracting zip file - people
will generally just want one of the formats, so downloading several
together isn't very useful.
</p></li><li><p>3dformat.htm: Update for v6 format (thanks to Mike McCombe).
</p></li><li><p>GPL.htm: Replace HTML version of licence with a link to the version on
the FSF website.
</p></li><li><p>ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
low level to be of interest to non-developers, and developers can look at
the source code.
<li><p>(Unix version): configure: New preferred name for specifying wx-config script
is WX_CONFIG.  WXCONFIG still supported for compatibility.
</p></li><li><p>(Linux version): Source RPM package dropped as you can just build an RPM
package from the source tarball.
</p></li><li><p>(Microsoft Windows version): The installer is now created with a newer
version of InnoSetup, which gives a 10% smaller download.
</p></li></ul><h1>Changes in 1.1.12 <small>(2007-02-07)</small>:
<ul><li><p>Remember the window size or maximised/fullscreen state between invocations.
</p></li><li><p>Add options dialog to "Export" similar to the one for "Print".
</p></li><li><p>The "number of pages required" in the print dialog now updates when you
change what is to be shown (underground legs/surface legs/station
</p></li></ul></p></li></ul><h1>Changes in 1.1.11 <small>(2006-11-25)</small>:
<ul><li><p>Updated Czech, Spanish, and Slovak translations.
</p></li><li><p>(MacOS X version): Assorted OS X specific tweaks and fixes.
<ul><li><p>Pick a smaller and clearer font for labels.
</p></li><li><p>Fix character spacing.
</p></li><li><p>Tweak display of bearing and elevation angles to look nicer with
proportional fonts.
</p></li><li><p>Use the title from the 3d (or plt, etc) file for the window title
rather than the filename.
</p></li><li><p>Show distances to 2 decimal places rather than the nearest integer.
</p></li><li><p>Only consider underground legs when calculating the depth bands and
depth colouring.
</p></li><li><p>Add "Colour by Error".
</p></li><li><p>Add entry for "white" in date and error keys.
</p></li><li><p>When setting the view to a single point, don't change the scale.
</p></li><li><p>If reloading the same file, don't change the view
</p></li><li><p>Fix filetypes selector in open dialog.

</p></li></ul><h1>Changes in 1.1.10 <small>(2006-07-14)</small>:
<ul><li><p>aven: Clicking on a survey name in the survey tree now highlights it in
the map view.  Double-clicking zooms the view to show the clicked survey
highlighted.  Clicking the root clears the highlighting and double-clicking
the root restores the default view.  To expand/collapse a branch, click
on the "[+]" or "[-]" icon to the left of the survey name.
</p></li><li><p>aven: The measuring line can now measure to anywhere in plan or elevation
view (not just to a station!)  In plan view the horizontal distance and
bearing are shown, while in elevation view the vertical distance is shown.
</p></li><li><p>aven: Moving the mouse over a station in the survey view now highlights
that station in the survey tree (though it may not be visible if the
survey(s) it is in aren't expanded).
</p></li><li><p>aven: Clicking on a station to centre the view now moves the mouse pointer
to the new location of the station (except on Mac OS X where this isn't
</p></li><li><p>aven: Fix which presentation toolbar buttons are shown as depressed.
</p></li><li><p>Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
</p></li><li><p>vim files are now installed with the correct paths (bug introduced in 1.1.9).
</p></li></ul><h1>Changes in 1.1.9 <small>(2006-07-04)</small>:
<ul><li><p>(Unix version): Install desktop files for aven and svxedit contributed to the
Ubuntu package by Phil Bull, and corresponding pixmaps.
</p></li><li><p>Fix img to filter out cross-sections which don't match the subsurvey (if
specified).  The API now returns img_XSECT_END to mark the end of a
passage rather than setting a flag on the last img_XSECT of the passage.
</p></li><li><p>Enhance integration with the vim editor - this can now colour .err files, run
cavern from vim and parse error output, and run aven from vim.  Tweak the
existing vim mode for .svx files to fix a few minor bugs and add support for
the new "*data passage" style.
</p></li><li><p>aven: fix drawing of the "blob" end of the measuring line on graphics cards
which can't draw large enough blobs for us.
</p></li><li><p>aven: sort out confusion about what encoding everything is in which means
that the distance measured by the measuring line actually gets displayed
and also fixes problems with empty menu items in non-English locales in
some cases.
</p></li><li><p>aven: redraw grey background after a menu is closed over the aven window
with no survey loaded.
</p></li><li><p>aven: fix bug which caused printing to crash (introduced in 1.1.8).
</p></li><li><p>aven: avoid crash on some machines when opening "About" dialog before having
loaded a survey.
</p></li><li><p>aven: Translate "Plan" and "Elevation" buttons in print view dialog.
</p></li><li><p>(Unix version): aven: Fix character set handling of cavern output.
</p></li><li><p>cavern: Report an error if a cross-section is specified for a station which
doesn't exist.
</p></li><li><p>Updated French and Italian translations.
</p></li><li><p>(Unix version): aven: Fix "Can't open message file `en_US' using path
`${prefix}/share/survex'" error.
</p></li><li><p>Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
(doesn't affect Survex itself, but other applications which use img.c should
update their copy).
</p></li><li><p>(Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
and later are caught by configure, whereas older wx versions are caught when
trying to compile).
</p></li></ul><h1>Changes in 1.1.8 <small>(2006.06.30)</small>:
<ul><li><p>Drop support for building with wxWidgets versions prior to 2.4.0
(which was released on 2003-01-07).
</p></li><li><p>aven: Printing through aven now uses settings from the "[aven]" section
of print.ini, and support for hierarchical sections (using "like=")
has been disabled.
</p></li><li><p>aven: Change mouse actions to be compatible with those in Survex 1.0.
The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
left drag is now smart about not rotating and zooming at the same
</p></li><li><p>aven: Highlighting stations now happens as you type, and pressing
"Enter" or clicking the "Find" button now pans and zooms to show the
highlighted stations.
</p></li><li><p>aven: Left-clicking away from a station now cancels measuring line.
</p></li><li><p>aven: Setting view to North, South, East, or West is now animated like
the tilt from plan to elevation.
</p></li><li><p>aven: Fix presentation saving to also write "." for decimal points and
presentation loading to accept either "." or ",".
</p></li><li><p>(Unix version): aven: Add text for all toolbar items so that aven
will work with the Gnome desktop preference for displaying toolbars as
icons with text or just text (wxWidgets needs fixing first though).
</p></li><li><p>(Unix version): aven: Remove the ability to detach the menu bar (yell
if you actually used it and I'll restore it!)
</p></li><li><p>aven: Add "all survey files" option to the "open file" dialog.
</p></li><li><p>(MS Windows version): aven: Fix cursor keys to pan survey.
</p></li><li><p>(MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
</p></li><li><p>(MS Windows version): Fix installer to work on Windows 2000 or XP if
run by an unprivileged user.
</p></li><li><p>(MS Windows version): Upgrade to the latest version of InnoSetup (the
installer builder we use) and include new installer translations for
UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
</p></li><li><p>(MS Windows version): aven: Include Catalan and Brazilian Portuguese
translations of messages for wxWidgets (the GUI library we use).
</p></li><li><p>aven: Disable "Highlight exported points" if there aren't any.
</p></li><li><p>Updates to French translation from Michel Bovey.  Also updates to German,
Italian, Catalan, Spanish, and Romanian translations.
</p></li><li><p>(Unix version): test suite: fix smoke test to pass even without X running
(it was meant to but the code had a bug).
</p></li><li><p>aven: Check if OpenGL is available and exit cleanly with a helpful error
if it isn't.
</p></li><li><p>(Unix version): aven: Fix --help and --version to work without a working
X display (provided it's built with wxWidgets 2.5.1 or newer).
</p></li><li><p>aven: Automatically select the presentation tab of the notebook when the user
selects "New Presentation" or "Open Presentation".
</p></li><li><p>aven: Fix "Delete" in the presentation list to not get passed on (and so not
reset to default view as well).
</p></li><li><p>aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
</p></li><li><p>aven: Fix Cursor Up and Down in the presentation list to move the highlight
up and down instead of being passed on and moving the survey.
</p></li><li><p>aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
Safari 2.0.3, and InkScape 0.42.
</p></li><li><p>aven: Put a 5mm border around exported SVG files to allow for station markers
and non-zero width lines.
</p></li><li><p>aven: Fix crash when exporting as SVG or Sketch if labels or surface data
was turned on.
</p></li><li><p>aven: Actually close the file we're exporting which fixes problems with it
not always being fully written.
</p></li></ul><h1>Changes in 1.1.7 <small>(2005.10.18)</small>:
<ul><li><p>cavern: Add validity checking for dates in *date commands (with feature
test in testsuite).  A date entered as just "year" or "year.month" now
becomes a date range for the relevant period (previously it became a single
date near the middle of that period).
</p></li><li><p>extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
with MS Windows).
</p></li><li><p>extend: Default output name for a file called input.3d is now input_extend.3d
rather than just extend.3d (which was annoying if you wanted to extend
several surveys in the same directory).
</p></li><li><p>aven: OpenGL 2.0 always includes support for point sprites so rework
our check for them to include that knowledge.
</p></li><li><p>aven: Regenerate depth bar if user switches to/from metric units.
</p></li><li><p>aven: Don't clear the "there" mark just because the mouse pointer has
moved off a station.
</p></li><li><p>aven: When processing a .svx file, put the resultant .3d file in the
same directory (since that's where we then try to load it from).
</p></li><li><p>aven: Fix labelling of date colouring on 32 bit platforms.
</p></li><li><p>aven: If "colour by date" is on and we load a survey with no date info
(or all surveyed on the same date) then set "colour by none".
</p></li><li><p>aven: Make the error dialog modal and remove a signal handler once it
has fired to prevent endless (or seemingly endless) cascades of error
</p></li><li><p>aven: Enforce a minimum object volume diameter of 1m to avoid problems
if a survey file with only one station in is loaded.
</p></li><li><p>aven: Fix problems with indicators disappearing when we're drawing
blobs and/or crosses the slow (but always supported) way.  (Problem
introduced in 1.1.6).
</p></li><li><p>(Unix version): aven: Really stop setting extra toolbar margin when using
GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
</p></li><li><p>(Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
we've been compiled with, and which GTK+/Motif version where appropriate.
</p></li><li><p>(Unix version): Fixed build on Fedora Core 3.
</p></li><li><p>documentation: Updates to 3d file format specification from Mike McCombe.
</p></li></ul><h1>Changes in 1.1.6 <small>(2005.10.10)</small>:
<ul><li><p>(MS Windows version): Distribution is about a third smaller than 1.1.5
(mostly because mingwm10.dll is no longer required).
</p></li><li><p>aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
it, showing cavern's output in a window (with errors and warnings clickable
to load the offending file into an editor), and then loading the resulting
3d file.
</p></li><li><p>aven: Added "Colour by Date" option.
</p></li><li><p>aven: Disable "Colour by Depth" option if there's no elevation variation.
</p></li><li><p>aven: Don't crash if trying to load a survey with no elevation variation.
Instead turn off depth colouring.
</p></li><li><p>aven: Export as HPGL added.
</p></li><li><p>aven: Improved update of mouse coordinates and measuring line (thanks to
Martin Green).
</p></li><li><p>aven: Show the coordinates of either the mouse pointer or the nearest
survey station to it (if there is one near enough).  Showing both was
confusing and meant the status bar overflowed on smaller displays.
</p></li><li><p>aven: When printing an extended elevation, don't show bearing and elevation.
</p></li><li><p>aven: Don't lock "flat" surveys which aren't extended elevations - a
flat survey with LRUD data isn't flat any more!
</p></li><li><p>aven: When we have to draw blobs and crosses the slow way (because the
graphics hardware doesn't support the fast way), draw them so that they
should appear at the correct depth into the 3D scene instead of on top
of everything else.
</p></li><li><p>aven: Make "play presentation backwards" icon green to match the other
presentation icons.
</p></li><li><p>(MS Windows version): aven: Mouse clicks on the survey view now set the
keyboard focus there.
</p></li><li><p>(MS Windows version): aven: Fix first redraw of a newly loaded survey.
</p></li><li><p>(MS Windows version): aven: Fix redrawing of measuring line.
</p></li><li><p>cavern: Store dates for img_XSECT.
</p></li><li><p>cavern: Fixed small one-off memory leak if you specify -o more than once.
</p></li><li><p>(Unix version): Check environmental variable LC_MESSAGES when deciding what
language to use for messages.
</p></li><li><p>(MS Windows version): "Print" on a 3d file now prints through aven rather
than the separate printer driver (Unix has done this for some time).
</p></li><li><p>Removed old printer drivers.
</p></li><li><p>img library: When creating a 3d file, ignore img_XSECT if we've been asked
to write a file format version which doesn't support it.
</p></li></ul><h1>Changes in 1.1.5 <small>(2005.09.20)</small>:
<ul><li><p>(MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
</p></li><li><p>aven: Make blobs round like they are in Survex 1.0.
</p></li><li><p>aven: If the graphics drivers don't support drawing blobs using OpenGL
point markers, fall back to drawing filled circles.
</p></li><li><p>aven: If the graphics drivers support it, draw crosses as texture mapped
OpenGL point markers which is much faster.
</p></li><li><p>aven: Cross size increased to match Survex 1.0.
</p></li><li><p>aven: We must update which blobs are displayed if display of surface or
underground legs is toggled.
</p></li><li><p>cavern: Fix handling of a *solve followed by survey data, none of which is
attached to the previous data.
</p></li><li><p>cavern: Fixed "No survey data" error when a *solve is followed by another
*solve (or the implicit solve at the end of processing) with no data between
</p></li></ul><h1>Changes in 1.1.4 <small>(2005.09.19)</small>:
<ul><li><p>aven: Added Aven's icon to the "About" dialog.
</p></li><li><p>aven: Use localised character for the decimal point (e.g. "," in most
continental European countries).
</p></li><li><p>aven: Previously the survey tree would get focus and then take keypresses
(e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
operate on the cave, and transfer the input focus across when we do.
</p></li><li><p>aven: Make pressing "Return" in the tree control expand/collapse a subtree.
</p></li><li><p>aven: Speed up intialisation by delaying creation of OpenGL lists until
they're needed.
</p></li><li><p>aven: Added Mark Shinwell's bounding box with shadow of the survey.
</p></li><li><p>aven: Disable the "Tubes" button/menu item when there's no LRUD data.
</p></li><li><p>aven: Reworded "Restore Default Settings" as "Restore Default View".
</p></li><li><p>(Unix version): aven: Set sensible default margins for printing and preserve
any margin values the user specifies between runs (previously margins
defaulted to 0 each time aven was run).
</p></li><li><p>Documentation: Document *DATA PASSAGE in the manual.
</p></li></ul><h1>Changes in 1.1.3 <small>(2005.09.07)</small>:
<ul><li><p>(Microsoft Windows version): Fixed build problems.
</p></li><li><p>cavern: Allow OMIT character (-) for left/right/up/down.
</p></li><li><p>aven: Remove an unnecessary menu separator.
</p></li><li><p>aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
</p></li><li><p>aven: Make the tooltip for "Hide" show the number of found stations.
</p></li><li><p>aven: If * or ? is used in a glob-style pattern, force a non-substring match.
</p></li><li><p>aven: Enable "New Presentation" when there's a 3d file loaded, rather than
when there's a presentation loaded.
</p></li><li><p>aven: Make entrances green in side panel tree list to match green blobs used
in cave view.
</p></li><li><p>aven: Don't show surface labels if we're not showing surface data, etc.
</p></li><li><p>aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
make "Space" the key for this.  Keep Return working "Stop Rotation" so
existing users are happy, but don't advertise it.
</p></li><li><p>aven: Normalise filename by adding any extension used, and use the normalised
filename for file history and window title.
</p></li><li><p>(Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
as the toolbar buttons already have a sensible margin - the extra margin is
only needed with GTK1.2.
</p></li><li><p>aven: Fix handling of plumb legs in tube model.
</p></li><li><p>aven: Fixed swapped L and R in tube model.
</p></li><li><p>extend: Preserve UD cross-section information in extended elevation.
</p></li><li><p>extend: Add new messages for John Pybus' enhancements.
</p></li></ul><h1>Changes in 1.1.2 <small>(never formally released)</small>:
<ul><li><p>Added support for LRUD data in .svx files, in .3d files, and aven can
now load and display it on screen and on printouts.  The ability to "fake"
LRUD data in aven is gone for now but will reappear in some form later.
</p></li><li><p>cavern: Removed support for writing Chasm's 3dx format.  We're going to
fold any desirable missing chasm functionality into aven.
</p></li><li><p>aven: Rearranged mouse actions as discussed on the mailing list.  Added
cursors for each different mouse action to help the user learn what each
does.  Also added cursors for the "compass" and "clino" as well as the
scalebar to suggest to the user that they can be dragged to change the view.
</p></li><li><p>(Unix version): aven: Don't segfault if LANG isn't a known language.
</p></li><li><p>tests/smoketest.tst: If X windows is running, check that we can run aven
with --help and --version.
</p></li><li><p>tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
no results are listed for it.  This revealed that there was a "newline" test
which should have been called "badnewline", and was a broken testcase too!
Fixed all these problems.
</p></li><li><p>cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
and omitted forward compass/clino readings in Compass DAT files.  Added
a feature test for this to the testsuite.
</p></li><li><p>It no longer makes sense to have an option not to build aven or to build aven
without OpenGL so remove old machinery for this from configure and the
</p></li><li><p>(Unix version): configure: Check if "-lXxf86vm" is needed.
</p></li><li><p>configure: Better output for strcasecmp test.
</p></li><li><p>aven: Fix crosses to work much better.  Not a total fix - their position
in the Z buffer isn't correct and they're rather slow to plot.
</p></li><li><p>aven: Don't regenerate the hittest grid every time the mouse moves while
animating, which solves the mysterious pausing effect (thanks go to Martin
Green for spotting this!)  Also clear all the status bar coordinates when
</p></li><li><p>aven: Sort out clashing menu shortcuts in some languages.
</p></li><li><p>aven: Fixed compilation problem on x86_64
</p></li><li><p>SPUD: Pruned out stuff which has been done or which is not actually relevant
to this branch.
</p></li><li><p>Merge various changes from 1.0 branch:
<ul><li><p>aven: Port over "printing from aven" functionality.
</p></li><li><p>aven: Port over "export as" functionality,
</p></li><li><p>Add David Loeffler's vim mode for .svx files.
<li><p>aven: Fix check for whether a label is behind us in perspective view.
</p></li><li><p>aven: Don't use an opengl list for drawing the indicators - we typically make
a new list each time we plot them anyway.
</p></li><li><p>Remove lingering traces of support for RISC OS and pre-386 MSDOS
</p></li><li><p>aven: Set icon on non-Windows platforms too.  This means that with
WindowMaker on Unix you get an icon on the AppIcon by default.
</p></li><li><p>configure: Update wxWindows checks to handle newer wx versions.
</p></li><li><p>Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
for anyone building from CVS).
</p></li><li><p>acinclude.m4: Quote macro name for fix autotools warning.
</p></li><li><p>Documentation: "tilt up" is "'" not ",".
</p></li><li><p>aven: Add support for mousewheels (to tilt the cave).
</p></li><li><p>aven: Fixed twisted transitions to and from pitches in certain cases.
</p></li><li><p>aven: Pick a sensible initial window size when the user's desktop is spread
over more than one monitor (works best with wx2.5 or newer, but try to do
better with wx2.4 or earlier as well).
</p></li><li><p>aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
contents being visible before any survey is loaded.
</p></li><li><p>aven: Allow a coloured texture to be used
</p></li><li><p>aven: Don't initialise until we have data (to the user, this means the window
is default colour (grey for most systems) not black until a survey is
</p></li><li><p>aven: Fixed weird "shadowed" icons.
</p></li></ul><h1>Changes in 1.1.1 <small>(2004-10-06)</small>:
<ul><li><p>(Microsoft Windows version): aven: Hopefully fix loading a survey file at
</p></li><li><p>aven: Delay loading the bitmap for the "About" dialog until it is first
needed.  We want start up to be as quick as possible.
</p></li></ul><h1>Changes between 1.0.32 and 1.1.0 <small>(never formally released)</small>:
<ul><li><p>NOTE: Survex 1.1.X releases are development snapshots made available for
the purposes of allowing wider testing and getting more user feedback.  Once
the code has stabilised the version number will be raised to 1.2.0.
</p></li><li><p>aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
you're using Windows 95 - these can be obtained from:
</p></li><li><p>aven: Solid passages - passage dimensions are currently inferred from
the leg length (pretty effective as you can measure longer legs in
larger passages).  Use of real LRUD data coming soon...
</p></li><li><p>aven: Depth colouring is now continuously varying.
</p></li><li><p>aven: Colour by depth can now be turned off (and there's the start of a
framework for properly implementing colour by date, error, etc).
</p></li><li><p>aven: Find stations moved onto the toolbar and now uses a simple wildcarded
match (? matches any character, * matches any number of characters).
</p></li><li><p>aven: We now use the status bar for coordinates, distances, etc to make
better use of screen space.
</p></li><li><p>aven: Full screen mode (F11).
</p></li><li><p>aven: Perspective view.
</p></li><li><p>aven: Context sensitive cursor shape - needs more work.
</p></li><li><p>aven: Mouse actions changed (hopefully they're now more natural, but
you may find the change disorientating - feedback wanted on this).
</p></li><li><p>aven: Added "presentations" which allow you to set up fly-through paths
and load/save/run them.
</p></li><li><p>aven: A presentation can be exported as a movie file.
</p></li><li><p>aven: Added Save screenshot facility.
</p></li><li><p>aven: Depth fogging option.
</p></li><li><p>aven: Added Smooth Lines option.
</p></li><li><p>aven: Added Textured Walls option.
</p></li><li><p>aven: If a survey has surface legs but no underground legs, default to
showing the surface legs.
</p></li><li><p>cavern: Dates given to *date are now stored in the 3d file.
