GlassFish v2.1 is an enabler for SailFin 1.0. In this release, we
have fixed around 500 issues since the GlassFish v2 release. In addition
to these bug fixes, several quality improvements were done including a
newer Shoal Group Management Service (GMS) and more robust Session
Replication. A newer MQ version 4.1.1 has also been integrated. In
addition to platforms tested in earlier releases, we have included
Windows 2008, OpenSolaris, RHEL 5 and Apache 2.2. Compare v2 and v3
to decide which one to use.
