The download is available at the Remoting download page . The structure is similar to the milestone releases; though it may be changing slightly for the next Beta. I expect that there will be at most one more Beta, followed by a CR series.

Javadoc is available online at the docs site ; bugs should be reported in the bug tracker (make sure you report the bug in the 3.0.0.Beta1 release). See the project page for more information.
