v1.3.1
       -- Backport #476
       -- Deprecate (& remove) `ENABLE_CCACHE` Option for CMake (c.f. #577)

Mar 27th, 2024
v1.3.0
       -- Deprecate more APIs which are replaced in develop (PR #572)
       -- Add support for CMake (PR #573)
       -- Add support for GitHub Actions (PR #573)

          to other functions like mp_invmod, mp_div, etc...
       -- Sped up mp_exptmod_fast by using new code to find R mod m [e.g. B^n mod m]
       -- minor fixes

v0.12  -- re-wrote the majority of the makefile so its more portable and will
          install via "make install" on most *nix platforms
       -- Re-packaged all the source as seperate files.  Means the library a single
          file packagage any more.  Instead of just adding "bn.c" you have to add
          libtommath.a
       -- Renamed "bn.h" to "tommath.h"
       -- Changes to the manual to reflect all of this
       -- Used GNU Indent to clean up the source
