8.2 Alpha2 has been posted to the downloads: http://www.jboss.org/teiid/downloads
This alpha adds a long overdue feature of exception handling in procedures. It also has the start of expanded native query support and an object/infinispan translator for cache as a source integration. We'll shoot for the first beta in early October. Be sure to log any issues found. There is still plenty of time to get things in.

It looks like we are good for alpha1. I'll begin preparing it unless there are any objections. We still have some integration test failures related rest war generation, but other than that we look good and there's been a lot of great work done so far.
