The preview version was announced at the RoboBusiness conference in Pittsburgh and can be downloaded here.
The 2008 version is quoted as having large performance improvements in inter-process communications, better handling of distributed-computing environments and improvements to their Visual Programming Language.
Surprisingly enough, I am downloading it at the moment and, after having a bit of a play with it, will do a write-up on any applications it may have in small/hobby robotics development.
