v2.0

 * Moved REXEC from SSLeay over to OpenSSL. Also made system
   configuration much simpler.

v1.3

 * Fixed a few (obvious) buffer overun bugs in new SSL 
   initialization and authentication code introduced in 1.2

v1.2 

 * Added server side implementation of distributed leases for
   dedicated access to a node using access control files.

 * Added unannouncement packets to provide hints for vexecd's from
   rexec client (when it can connect) and from rexecd (when it it 
   starts a lease)

 * Fixed some off-by-one buffer overrun bugs.

 * Fixed stdin forwading bugs (EOF still an issue).

 * Factored out SSL initialization and authentication code.

v1.1

 * Made code a bit more portable. Now compiles and runs on Solaris as
   well as Linux. Job control (fg/bg) on Solaris still doesn't work
   quite right though.

 * Now using condition variable to wake up multicast thread when it
   needs to send announcements.

 * Now using randomized (within a [min,max] interval) heartbeats and
   announcements to prevent nodes from becoming synchronized in their
   sending of these.

 * Fixed null termination bug in cli_setup_env that was causing
  'Strange exit' errors from time to time.

 * Using getloadavg.c from GNU make to get load average for various
   OS's.

v1.0

 * First release of REXEC software.
