Ladybridge Systems have today released version 2.11-0 of the QM
multivalue database.

This version introduces the data replication element of the resilience
features package. The second element, journalling, will follow in the
near future.

QM's replication package allows cascade replication where data can be
replicated onward through a chain of servers and symmetrical
replication that can be used to replicate in both directions between
two systems subject to some rules to handle concurrency control. We
are hoping to publish an article describing practical use of
symmetrical cascade replication in the near future.

This release also contains many other new features requested by our
users. See the openqm.com web site for full details.
