JBoss Messaging 1.2.0.Alpha1 has been released and it is available for download on jboss.org (http://labs.jboss.com/portal/jbossmessaging/downloads) and sourceforge (http://sourceforge.net/project/showfiles.php?group_id=22866&package_id=157261).
This is the fist Messaging release that introduces elements of clustering.
The final 1.2.GA release, due in February 2007, will provide a highly sophisticated clustering implementation, which will allow smooth distribution of the application load across the cluster, intelligent balancing with no single point of failure, high availability and transparent fail-over.
The current alpha release offers support for distributed destinations. For an overview of this release's features, consult the new ClusteringGuide included with the release bundle. You will also find a distributed topic example that runs out of the box, which will help you getting started with the new clustering features.
Please be aware that the current release is a preview alpha release. We strongly advise against using it in a production environment.
