1.2. About this release
JBoss Enterprise Application Platform 5.1.2 is a minor release. Minor releases aggregate the contents of prior patches and Cumulative Patches (CPs), and may add functionality. Subsequent patches and Cumulative Patches assume the installation of the minor update that preceded them.
During the life cycle of a product's major version, Red Hat makes commercially reasonable efforts to maintain API-level compatibility across all minor releases and asynchronous patches, ensuring that, for example, JBoss Enterprise Application Platform 5.1.2 maintains API-level compatibility with JBoss Enterprise Application Platform 5.0.0, the initial release of JBoss Enterprise Application Platform 5. Possible exceptions to this rule include fixes addressing critical security issues.
PicketLink (offered to customers at v1.0.3 in JBoss Enterprise Application Platform 5.1.1) is graduating from Technology Preview to v2.0.1 GA.
With the release of JBoss Enterprise Application Platform 5.1.2, JBoss Enterprise Application Platform 5 customers should update to this release.
