[fitsbits] WCSLIB 8.1 released {External}

[Mark Calabretta]

Greetings,

WCSLIB 8.1 is now available:

  http://www.atnf.csiro.au/people/mcalabre/WCS/wcslib-8.1.tar.bz2

also via ftp from

  ftp://ftp.atnf.csiro.au/pub/software/wcslib/wcslib-8.1.tar.bz2

It includes WCSLIB 8.0, which was a beta release.

The main change was to expand the auxprm struct to accomodate additional
planetary-based keywords.  The changed ABI requires the major version
number to be incremented.

WCSLIB version 8.1 (2023/07/06)
-------------------------------

Changes in the contents of the auxprm struct (in 8.0 beta) necessitated
incrementing the major version number from 7 to 8, i.e. the ABI changed.
Took the opportunity for minor tweaks to wcsprm and disprm.

* C library

  - In disprm, changed the order of maxdis and totdis to ensure correct
    alignment of doubles on 32-bit machines.

* Fortran wrappers

  - Match changes to disprm in the C library.

  - In the Fortran test suite, inserted a brief pause between plots in
    tprj2, tspc, and tpih2, which have long been a blur.

* PGSBOX

  - Quell innocuous compiler warnings from gfortran 12.1.0.  Inserted a
    brief pause between plots in pgtest and cpgtest.


WCSLIB version 8.0 beta (2023/07/01)
------------------------------------

Beta test version, not publically released.

* C library

  - Support planetary keywords A_RADIUS, B_RADIUS, C_RADIUS, BLON_OBS,
    BLAT_OBS, and BDIS_OBS in auxprm by analogy with the Solar keywords
    added at 7.1.  Requested by Chiara Marmo (Observatoire de Paris).

  - Added wcsprm::time to the wcsprm struct to record the TIME axis
    number (along with lng, lat, and spec).

  - Fixed a bug in wcspih() and wcsbth() where trailing blanks were not
    stripped from string keyvalues.  Reported by Naveen Dukiya.

    Changed test program tdis3 to test this.

  - Fixed a problem affecting thread safety in disp2x(), disx2p(), and
    diswarp().  Reported by Mohammad Akhlaghi.

* Fortran wrappers

  - Match changes to the C library supporting planetary keywords in
    auxprm and the addition of wcsprm::time.

* User manual

  - Documentation generation moved to doxygen 1.9.7 (was 1.9.5).
