WCSLIB version 7.8 (2022/03/25)
-------------------------------

* C library

  - In wcssub(), bug fix for tabular coordinates that change axis
    number, thus requiring tabprm::map to be updated.  Reported by
    Mihai Cara with patch.

    Also in wcssub():
      - check that all axes of a multi-dimensional table are extracted
        together,
      - fixed potential memory leaks for tabular coordinate axes when
        an attempt to subimage non-separable axes fails,
      - the error messages for non-separable coordinate systems are
        generally more informative,
      - subimage extraction by coordinate type now recognises time
        coordinate axis types via WCSSUB_TIME.

  - wcsset() now identifies time coordinate axes in wcsprm::types.

  - Extended test program twcssub to test the above modifications.

* Installation

  - Bug fix in the utils makefile for creating $(MANDIR)/man1.
    Reported by Aleksander Kurek.

  - Bug fix in the Fortran makefile for compiling and using 'tofits'.
    Reported by Stefan Brüns.

* User manual

  - Documentation generation moved to doxygen 1.9.3 (was 1.9.1).
