Release Notes for JBoss Cache Habanero 2.0.0

** Sub-task
    *  [ JBCACHE-542 ] Fix initialization of Node.IdentityLock to actually lazy create

    *  [ JBCACHE-914 ] Adapt JBCACHE-913 fix for JBC 2.0
    *  [ JBCACHE-958 ] Add unit tests of JBCACHE-955

** Feature Request
    *  [ JBCACHE-9 ] Streaming state transfer, for large states
    *  [ JBCACHE-57 ] Interfaces for accessing JBossCache
    *  [ JBCACHE-541 ] Create one true Node class; that's lean and mean and stuff

    *  [ JBCACHE-834 ] Combine eviction RegionManager with generic RegionManager
    *  [ JBCACHE-869 ] Use Marshaller for all forms of serialization, not just replication.
    *  [ JBCACHE-880 ] Add expiration policy for nodes based on a node's expiration key
    *  [ JBCACHE-908 ] Marshalling for state transfer should go thru the VersionAwareMarshaller fwk

    *  [ JBCACHE-955 ] Restore ability to insert and remove child nodes with only a read lock on the parent
