              Release Notes: Blitz's core indexing and cache code was updated to remove several race conditions and improve both memory usage and performance. The Jini registry dumping tool was enhanced to support more methods for specifying target registries. It is now possible to have user-code executed at boot time once the space is initialized but prior to the proxy being published. Dispatching of blocked operations was reworked to be more cache friendly and faster.
