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

Changes in 1.4.11 (2024-08-14):

* aven:

  + Add imperial scales for export and printing.  Fixes #132, reported by Eric
    C. Landgraf.

* aven/survexport:

  + HPGL export now uses pen 2 for splays and pen 3 for surface legs.  Partly
    addresses #60.

  + HPGL export now supports scaling (previous the scale was always
    1:40000).

  + KML export now distinguishes surface legs and splays using different
    line styles.  Partly addresses #60.

  + Remove Skencil export support.  The last release of Skencil was in 2005.
    There was an attempt to revive the project in 2010, but that didn't lead to
    another release and seems to have petered out.  No current Linux distro (or
    other package system) seems to have Skencil packages, and the current git
    version still appears to require Python 2 which is being phased out.

* cavern:

  + Support `*data ignore` to allow ignoring a block of survey data lines.
    Closes #114, reported by Alastair Gott.

  + Report error for bad final reading in `*data` command (previously such a
    bad reading was quietly ignored).

  + If the survey in `*end` doesn't match that in `*begin` the location of
    that `*begin` is now reported as well - the second message here is new
    for example:

     badbegin.svx:6:8: error: Survey name doesn't match BEGIN
      *end   bar
             ^~~
     badbegin.svx:4:13: info: Corresponding BEGIN was here
      *begin      foo
                  ^~~

  + Now shows a context line for a reading which was on the previous line,
    which can happen for interleaved data styles.

  + Warn when a token is not followed by a blank, comment or end of line.
    This is an unintentional tokenisation oddity which has been present
    for a really long time.  We don't want to break files that rely on this
    (even if they likely only do accidentally) so emit a warning rather than
    an error.

    This warning can easily be eliminated by adding a space where indicated,
    which will work with old and new Survex versions.  Fixes #135.

  + Errors and warnings which report an unexpected token now report a
    contiguous span of letters and numbers rather than just letters in cases
    where a number can't follow (which is the majority of cases).

  + If `*require` isn't satisfied, the `*require` line is now shown for
    context (especially helpful if there's a comment after the command noting
    the reason for the requirement, as we now suggest in the manual).

  + `*require` version parsing improved - spaces are no longer tolerated in
    a version number and trailing junk after the version number is now
    handled more consistently.

  + Fixed several situations in which the highlighting of the context for a
    diagnostic was off by a small number of columns.

  + Optimise building of matrix during network solving.

  + Enhancements and fixes to reading Walls WPJ and SRV files:

    - After reporting an error for an unsupported datum, we now set the datum
      to WGS84 to prevent triggering further errors from code which tries to
      use the datum.

    - Parse Walls WPJ commands as alphanumeric rather than alphabetic tokens,
      which better matches how Walls parses them.  This only makes a difference
      in the error message when we don't recognise a WPJ command.

* Documentation:

  + Note `feet` are international feet and how to select a different
    definition in `*units` docs.

  + Document `grads` are also known as "neugrads" and "gons" in `*units` docs.

* Assorted translation updates.

* testsuite:

  + Fix bug in normalisation of `-0.00` to `0.00` in DXF output before
    comparing with expected output.

* Update and improve vim syntax highlighting:

  + `*cartesian` added

  + `*data ignore` added

  + `mils` units now highlighted as deprecated

  + `UP` and `DOWN` are no longer highlighted anywhere in a command

  + `U`, `D`, `LEVEL`, `-V`, `+V`, `.`, `..` and `...` now highlighted in data
    lines

  + Repeated `NOT` in `*flags` is now highlighted as an error

  + Fix error highlighting for unquoted `*include` to not flag an error just
    because there's a comment after the filename

  + Fix error highlighting for unquoted `*include` to work when there's
    whitespace between `*` and `include`
