With a short delay the Release Candidate 2 (RC2) of the 4.1 stream is available.
Note, that we don't have reworked the documentation yet! (But we will within the next days)

The jars are available from the updatesite at http://www.openarchitectureware.org/updatesite/milestone/site.xml

You can also download a zip file containing the jars from here.

We now have a maven2 repository (probably with small issues - As we don't use maven2 for our build, we've written a small batch converting the updatesite jars into a corresponding m2 repository)
You can find it here http://www.openarchitectureware.org/m2. Note, that we will add new SNAPSHOTS on a regular basis. We will deploy the 4.1 final release to ibiblio.org, too.
