Subject: [fitswcs] WCSLIB 8.6 released {External}
Message-ID: <20260330014805.54f26aaa@horus>

Greetings,

WCSLIB 8.6 is now available from

  https://www.atnf.csiro.au/computing/software/wcs/wcslib-releases

This is a minor release as per the change log appended below.  The fix
to PGSBOX also carries over to the utility program, wcsgrid, provided
with WCSLIB.

WCSLIB version 8.6 (2026/03/30)
-------------------------------

* C library

  - In linx2p(), replaced two uses of goto statements to work around an
    apparent compiler bug.  Reported by Cyril Richard.

* PGSBOX

  - PGSBOX now accounts for the possibility that the coordinate system
    is not defined outside the frame.  Previously this was important for
    determining axis crossings and hence axis labelling.  However, it is
    not valid for -TAB coordinates in FITS for which extrapolation is
    strictly limited to half a pixel.  

* User manual

  - Documentation generation moved to Doxygen 1.16.0 (was 1.15.0).
    While the Doxygen bug reported in version 8.5 has now been fixed,
    the makefile patch has been left in place for the time being.
