Hi,

See http://www.jboss.org/jbossas/downloads/ Jboss 6 Final is out.
When is JBoss in Action: Configuring the JBoss Application Server for Jboss 6 coming out.
There are lots of exciting technologies such as JEE6 etc that is now standard with Jboss 6.

In our company JBoss in Action: Configuring the JBoss Application Server became the gold standard as a reference for Jboss 5. We hope a new version of this book for Jboss 6 will be coming out soon with the same quality as we want to get it.

Thanks
