The Slony team is pleased to announce the first official release of 
version 2.2 of the Slony replication engine.

Slony 2.2.0 adds the following major features to Slony 2.1.x

* Slony now uses the COPY command for replicating data between providers 
and subscribers.  This will result in faster replication times and more 
efficient resource utilization on the replica for many workloads

* The FAILOVER command has been made more reliable for complex cluster 
configurations.   The FAILOVER command now supports the failure of 
multiple nodes at the same time.  All users of the FAILOVER should read 
the documentation to familiarize themselves with these changes

* Multiple versions of slony can now be installed under the same 
PostgreSQL cluster.  The Slony shared libraries, functions and .sql 
files are now versioned to support this
