Shake Well Before Use

We strongly recommend that you take advantage of the release candidates as they come out. Waiting for a GA release is only going to set you up for unpleasant surprises. A GA is simply a tag and nothing more. Note that CAS releases are strictly time-based releases; they are not scheduled or based on specific benchmarks, statistics or completion of features. To gain confidence in a particular release, it is strongly recommended that you start early by experimenting with release candidates and/or follow-up snapshots.

In order to start experimenting with release candidates, at any given time, you should be able to append -SNAPSHOT to the CAS version specified in order to take advantage of snapshot builds as changes are made and published.
