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

Changes in 1.4.19 (2025-12-17):

* aven/survexport: Rework PLT export to use 2 character escapes for spaces
  and other characters which aren't valid in Compass station names.  We were
  using 3 character escapes, but that's unhelpful since Compass has a 12
  character station name limit.

* cavern: The syntax of *instrument commands is now checked and a warning
  issued for problems.  The information in the command is still not yet used.

* cavern: Improve description of --quiet option.  Reported by Wookey.

* (Microsoft Windows version): The installer now always updates DLLs it
  installs rather than skipping DLLs which declare the same version number.
  This avoids problems when DLLs change in an upwardly but not downwardly
  compatible way but keep the same version number.  It also means downgrading
  now gives an install more like installing the older version from scratch
  would.  Our DLLs are all private and installed into our own install directory
  so there are no concerns with breaking other installed software.  Fixes #145.
  Reported by Footleg and Juan Corrin.

* Fill in some missing Czech translations.

* Update unofficial Inno Setup translations for the installer.

* We now require at least FFmpeg >= 3.2 to build Survex.  This version was
  released in 2016 so should be easily available everywhere now.

* (Microsoft Windows version): Drop workaround for wx-config --rescomp not
  working as this has now been fixed in the mingw package of wxWidgets.

* Test suite:

  + Add test coverage for `*data normal` without `clino`.
