It's not often I talk about the individual projects at jboss.org, but in this case, I think the latest release of JBoss Cache deserves special mention. When you consider that our currently shipping EAP 4.3 release includes JBoss Cache 1.4, and the JBoss Cache developers just went GA in the community with their 3.0 release, the innovation engine is really heating up.
We released EAP 4.3 on January 11, 2008 (if memory serves me right), and in the intervening 10 months the JBoss Cache developers have release JBoss Cache 2.0, 2.2, and now 3.0. That's right, two major releases and a minor in ten months. This doesn't include any bug fix releases, and support of the currently shipping version! An awesome job, and its just another example of the strength of the open source development model. One of the other things that deserves special mention, is that JBoss Cache implements a new concurrency model called MVCC or multi-version concurrency control. This model provides for a transactional cache that can scale very well. The JBoss Cache team has done some extensive benchmarking, and the results are spectacular! Finally, because they have moved so fast, we have been able to include JBoss Cache 3.0 in the upcoming community GA release of AS 5! This in turn will become the release in our upcoming EAP 5!
Finally, for all the gory details, I'll point you to the JBoss Cache blog post announcing the release, and it has links to everything you need.
