VERY IMPORTANT NOTE:
This release of the JasPer software introduced some changes in the API
and/or behavior of the library relative to earlier releases, which may
necessitate some small changes in code using the library (e.g., to avoid
memory leaks or other problems).  Please refer to the "News" section
of the JasPer Reference Manual for more details.  For convenience,
this manual is available online (for various JasPer releases) at:
    https://jasper-software.github.io/jasper-manual

* Greatly improve documentation.
* Add support for multithreading.
* Add some customization points in the library, such as the memory allocator
  and error logging function.
* Add improved memory usage tracking and limiting.
* Add experimental partial encoding/decoding support for the HEIC format.
* Fix some longstanding issues in the JasPer I/O streams API.
* Add the running of the full test suite in CI builds for the Windows platform.
  (Previously, the full test suite was only run for CI builds on Unix-based
  platforms.)
* Fix many bugs (e.g., #305, #307, #308, #309, #312, #314, and many others
  not associated with any issue numbers).

* New option -DJAS_ENABLE_HIDDEN=true to not export internal symbols in the public symbol table

* Fix various memory leaks

* Plenty of code cleanups, and performance improvements

* Some macros were changed to inline functions.  This has to potential to
  impact some code that made assumptions about the implementation.  Some
  potentially impacted macros include:
      jas_matrix_numrows, jas_matrix_numcols
      jas_matrix_get
      jas_seq_get, jas_seq_start, jas_seq_end
      jpc_ms_gettype
      jas_matrix_set and jas_seq_set is affected differently; the old macro was
      an actual expression returning the value, while the new function does not.
  The following macros have been changed, too, but are likely not
  affected, since they have been an rvalue-expression anyway:
      JP2_DTYPETOBPC, JP2_BPCTODTYPE
      JAS_IMAGE_CDT_{SETSGND,GETSGND,SETPREC,GETPREC}
      jas_image_cmptdtype
      macros from here
      jas_matrix_setv, jas_matrix_getvref
      jas_matrix_bind{row,col}
      the jpc_fix_ family
      the JPC_QCX and JPC_COX families
