The Mule development team is very pleased to announce the first Release Candidate for 2.0, the next generation of the Mule ESB, and believe it or not we even have some documentation available!

First take a look at Whats New in Mule 2.0 for an overview, then jump into the Mule 2.0 Configuration Guide to see how a 2.0 Mule config compares to a 1.4 config.

For those interested in creating an XML Namespace for their custom module/transport (or just want to know the gory details of how it works), read How to Create an XML Namespace

A lot of work has gone into Mule 2.0 (see the 425 issues listed in the Release Notes, for example), so we'd really like you to try it out and let us know how it goes.

One more thing worth mentioning is that we have been continuously merging in fixes from 1.x, so any issue resolved for 1.4.4 should also be resolved in 2.0
