- A new --ndb-log-transaction-id option is added to the MySQL Server
 - A new NDB$EPOCH_TRANS() conflict detection algorithm is added
 - Five new status variables for tracking the behaviour of transactional 
   conflict detection.

The NDB$EPOCH_TRANS() function is similar to NDB$EPOCH, except that 
detected conflicts result in rejection and realignment of not just the
conflicting rows, but their transactions, and any transactions 
transitively depending on them.  This gives eventually consistent 
asynchronous replication with cross-row transaction consistency.
