Today marks the official release of Apache.NMS.ActiveMQ v1.5.3. We put a lot of work into this one fixing bugs that were found since the 1.5.2 release. Some really nice performance fixes in this release along with some thread leaks and concurrency errors.
For anyone on v1.5.2 I'd definitely recommend upgrading, there were a couple issues that should make failover recovery of consumer much more reliable.
Grab in from the Apache.NMS.ActiveMQ downloads page.
