The Slony team is pleased to announce the release of the first beta for 
Slony 2.2.0.

Slony 2.2.0 will be the next major release of the Slony-I replication 
system for PostgreSQL.

Key features of this release include:

* The storage and transport and application of the slony log 
(sl_log_1/sl_log_2) has changed providing performance improvements. Data 
is now stored in a different format and the postgresql COPY protocol and 
triggers are used to replicate and apply changes to replicas.

* DDL handling with the EXECUTE SCRIPT command has changed.  The DDL is 
no longer stored as a special event in sl_event but is instead stored in 
sl_log_script and is processed as part of a SYNC event inline with data 
changes.

* FAILOVER has been reworked to be more reliable but not all nodes can 
be used as failover targets.

* A RESUBSCRIBE NODE command was added because the provider of a 
subscribed set can no longer be changed with the SUBSCRIBE SET command 
in some cases.  All sets from a particular origin must send data to 
receivers through the same path/forwarder nodes. This must remain  true 
during cluster reshaping.


Numerous bug fixes.  See the release notes for details.
