Release 1.0 rc3
---------------------------------------------------------------------

NEW FEATURES:
- With this release we are feature complete for the 1.0 release!
For 1.0 you should not expect more features to be added.


NOTES:
- Intern table OJB_HL_SEQ (used by SequenceManagerHighLowImpl)
  has changed! Now need an additional column 'VERSION' of type INTEGER
  When updating from earlier version drop/reinstall table with additional field
- PersistenceBrokerAware interface changed, methods beforeStore and afterStore
  split into xxxInsert/xxxUpdate methods, all methods now expect an PersistenceBroker
  argument
- PersistenceBrokerListener interface replaced by PBStateListener
- ManageableCollection interface add new method afterStore(...)
- Remove obsolete method 'invalidate(Identity oid)' from PB-api


CHANGES:
- enhanced PB-api listener classes
- unitized handling of events in PB-api
- adapt sequence manager implementations using 'long' instead 'int' keys
- SequenceManagerHighLowImpl now use optimistic locking to support sequencing
  across different JVM (except j2ee conform app server, see sequence manager doc).
- Add new attribute 'autoNaming' to sequence manager implementations. Now
  the implementations allow to switch on/off auto-generating of sequence names
