A third milestone release of the JBoss Java Application Server (AS) 6 series is now available.

JBoss AS 6.0.0.M3 introduces container managed concurrency and singleton beans. With this release, HornetQ replaces the JBoss Messaging JMS and MDB implementation. The embedded AS project is also now part of the distribution, and RepositorySelector is integrated into JBoss Server.

A full run-through of the new features, bug fixes and improvements, is available at the Release Notes.
