JBoss Messaging 1.4.0.CR2 has been released and is available for download. http://labs.jboss.com/jbossmessaging/downloads/jboss-messaging-1.4.0.CR2.zip This is a candidate release for JBoss Messaging 1.4.0. This release fixes several important bugs from the previous release, full details of which can be found in the release notes. The other major changes in this release relate to improvements on the persistence and fixes on ClusteredConnectionFactories. Before CR2 the ClusteredConnectionFactory would receive notifications only if a Connection were still alive. After CR2, every time you lookup for a new CF on the JNDI the ClusteredConnectionFactory will have a special callback to receive any topology changes from the server. The LoadBalancing and Failover will aways have the most updated info. JBoss Messaging 1.4.0 is also Java 5 only. This is because we build against JBoss AS 4.2 whose libraries are built against Java 5 only. We need to have our libraries synched up with AS 4.2 in order to be fully integrated with it. Enjoy!
