The team has been banging away on 0.6 and the end is nigh.  Here's a quick look at the features available in 0.6 Beta1:

• Security policy now supports pluggable authentication providers with PicketLink and PicketBox integration out of the box.
• Transaction policy definitions for starting a global or local transaction around a service.
• A ton of work around improving the visual editor and adding support for new features in 0.6.
• Added RESTEasy gateway
• Added a vanilla HTTP gateway
• Dynamic operation selectors
• Operation-level drill down for service monitoring
• Enhancements to the rules and bpm components around fact insertion and event notification
• Easy peasy deployment and testing of quickstarts
• Improved Camel integration in core and test framework
• More bug fixes than you can shake a stick at

We started the typical Release Overview page for 0.6, but it's still a work in progress.  Definitely check it out for more info and updates as we move closer to 0.6 Final over the next couple weeks.
