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

Changes in 1.4.8 (2024-04-23):

* cavern:

  + The warning for a compass reading on a plumbed leg was already suppressed
    for a compass or backcompass reading of 0, but is now also suppressed for a
    backcompass of 180° (or equivalent) which seems to be common in some Compass
    datasets, but also seems sensible generally.  Thanks to Simeon Warner for
    sharing some data which triggered such warnings.

  + The error for when a survey and station use the same name is now also
    emitted in the case where a name was used first for a station, and then as
    a survey on an explicitly prefixed name.  Closes
    https://github.com/ojwb/survex/pull/4, reported by Thomas Holder.

  + The error for when a survey and station use the same name now highlights
    the problematic name within the line shown for context.

  + Fix the reported token string reported by some errors with readings.  This
    happened to work on at least x86-64 Linux, but the code was invalid and
    failed on some architectures.

* Fix to build with newer FFmpeg versions.

* (Microsoft Windows version): The installer now offers the choice to install
  for just the current user, which allows installing Survex without admin
  rights.

* (Microsoft Windows version): Fix problems with valid coordinate systems being
  rejected and aven's cavern log window not showing output.  Reported by
  Peter Mašič, Špela Borko, Răzvan Dumbravă and detrito.  Thanks especially to
  Špela Borko for a lot of testing to help track down the cause.
