With only one week delay (see JBoss AS 6 release date published) JBoss has today released the first release candidate/candidate release of the exciting new JBoss AS 6.
As mentioned before, this will give JBoss developers access to the wealth of improvements brought by Java EE 6. See my Java EE 6 progress page for details about those changes.
Interesting additions are the shared library mode (JBAS-8304) and JBoss Cache now being replaced by Infinispan (JBAS-7837). Hopefully this will also end the long standing memory leaks in CDI (JBAS-6545).
