[Olly Betts]

Survex 1.4.4 is now available:

This release is mostly a collection of minor bug-fixes for aven, plus a
couple of small new features.

Here's the full NEWS file entry for this release:

Changes in 1.4.4 (2023-02-03):

* aven: Fix red line in clino background to be grey (this was introduced in
  1.4.3 and was a debugging change accidentally left in).

* aven: Accept weird .3d files from Therion which have empty components in
  station names.  That's not really valid by Survex's definition of station
  names, but it's not very helpful to reject such files, so just disable the
  checks that were rejecting this.

  The result is empty entries in the survey tree, but I don't see what we can
  really do that's better than that.

  Reported by Vasily Vl. Suhachev.

* aven: Make it more obvious you can enter a custom scale by adding a "..."
  entry to the scale combobox - selecting this clears the value and gives focus
  to the combo box text entry. This control has always supported clicking to
  enter a custom scale, but there wasn't really any indication that this was
  possible before.  Partly addresses #132, reported by Eric C. Landgraf.

* aven: Force export window to resize when the export format is changed as
  different controls are shown depending on the export format.

* aven: Right-align tilt spin control value in print/export dialog to match the
  bearing spin control.

* aven,survexport: Add ability to export as Survex 3d which is useful as you
  can filter to a subset of surveys, filter out splays, convert from other
  formats the img library can read, etc.  This feature is a bit rough and ready
  currently but please report issues.

* dump3d: Add --legs option which converts MOVE and LINE to a single LEG line
  per leg with the from and to coordinates.  Tools which parse dump3d output
  should find this easier to process as it avoids having to track a "current
  position".

* Update manual to have a complete list of quantities which *calibrate accepts.

* cavern.tst: Fix testsuite to work with SOURCE_DATE_EPOCH set.
