                         Regina 2.0
                         13 Mar 2000

  The version numbering of Regina has changed.  Anders' original intent
  was for Regina to be released as version 1.0 when it achieved
  100% ANSI Compliance.  I originally concurred with this approach
  by releasing the 0.08 series, but with this release, Regina has
  changed internally sufficient to warrant a major version number
  change.  By continuing to release version numbers of 0.xx, the
  implications are that Regina is not a mature product. Obviously,
  this is not the case, and rather than confuse the situation and
  release a version 1.0, version 2.0 was decided upon.
  Anders is aware of the change and is happy with the change
  provided there is no confusion with users. Hopefully that isn't
  the case.

Changes in this release (from 0.08h)

o Added thread support. Support available for platforms that use
  Posix Threads, Win32 threads and OS/2 threads.  This is the first
  version of Regina with thread support, so don't expect a flawless
  implementation yet. 
  Platforms that are known to work:
  - Linux RedHat 6.1
  - Windows NT/98/2000
  - Solaris 2.5 using gcc
  Platforms that are known not to work:
  - Linux RedHat 5.1 - threads library too old
  - Digital Unix 4.0 - compilation errors
  OS/2 thread support is only available with EMX, and that hasn't
  been tested thoroughly.
o A new sample program; threader, has been written to demonstrate
  Regina's multi-threading capabilities.
o Removed limitation on maximum value of NUMERIC DIGITS. Now no
  effective limit.
o Regina now returns a tokenised version of a Rexx program via
  RexxStart() that can be re-loaded from another session.
o Regina can now be built on the Amiga with gcc.
o Fixed "groundhog day" bug with TIME('L'), where times at .5 second
  would be rounded up to the next second.
o Regina's stack usage has been dramatically reduced.
o Removed limitation of nested functions and loops. Now no effective
o Reduced common global symbols in the library. Reduced symbols
  in shared libraries (ELF format) and DLLs.
o Changed the method for Unix installation. Should now work on all
  Unix platforms.
o Fixed bug with CALLing external routines with parameters; eg
  CALL "extrout" parm1

Once again Florian Grosse-Coosmann has made the majority of the 
contributions to the success of this release. 

Cheers, Mark.
