--- Comment #4 from Karel Piwko kpiwko@redhat.com --- The reason why 1.0.0-beta-7 is preferred instead of:
* 1.1.0-alpha-3 => this is a dead branch with incompatible API * 2.0.0-alpha-1 => this is a cutting edge branch with unstable API
1.0.0-beta-7 is the only version which is actually supported together with JBoss AS 7. The plan is to skip 1.1.0-X altogether and update to 2.0.0-X once it becomes a production quality with next AS7 update.
