GENESIS version 2.3 is now available, and we recommend that all GENESIS
users upgrade to the new version.  GENESIS 2.3 supercedes version 2.2.1,
and has a number of changes in the simulator source code to allow use on a
greater variety of platforms including Intel and AMD 64 bit processors,
MacIntosh with OS/X, and Microsoft Windows with the Cygwin environment.  It
includes Kinetikit Version 11, and revised documentation.  We expect that
GENESIS 2.3 will be the last GENESIS 2 release, as we hope to begin
preliminary releases of GENESIS 3 sometime in 2006.

Binary distributions are also available that include precompiled versions
of the 'genesis' and 'nxgenesis' (GENESIS without X11 graphics)
executables.  At present these are for Linux, Microsoft Windows with
Cygwin, and Mac OS/X.

The new release of Parallel GENESIS (PGENESIS 2.3), which now has support
for MPI as well as PVM, is also available.  PGENESIS should run on almost
any parallel cluster, SMP, supercomputer, or network of workstations where
MPI and/or PVM is supported, and on which serial GENESIS itself is
runnable.

For more information, see the 'README' file in this GENESIS downloads
directory.
