This is a long overdue maintenance release. Fixes about 20 issues and includes two significant improvements. The first is the elimination of the Throttle. Originally included to artificially constrain threads, requests, and transactions to improve performance on certain infrastructure. It's not as much of an issue anymore and today the Throttle caused more problems than it solved. So bye-bye. :-) The only real impact you'll see is that the maxSessions/maxTransactions/maxRequests no longer have any effect whatsoever. They remain in the DTD only for backward compatibility. The other new change is built-in support for enums out of the box! It's currently a Beta release as per our process. But if all goes well over the next week or two, we'll vote to promote it to GA. The best thing you can do is test it out for us!
