[ANNOUNCE] Apache ZooKeeper 3.3.0

The Apache ZooKeeper team is proud to announce Apache ZooKeeper version 
3.3.0.

ZooKeeper is a high-performance coordination service for distributed 
applications. It exposes common services - such as naming, configuration 
management, synchronization, and group services - in a simple interface 
so you don't have to write them from scratch. You can use it 
off-the-shelf to implement consensus, group management, leader election, 
and presence protocols. And you can build on it for your own, specific 
needs.

Key features of the 3.3.0 release:
* observers - non-voting members of the ensemble, scale reads 
http://bit.ly/9wPnpq
* distributed queue recipe implementation (c/java)
* additional 4letterword/jmx features to support operations
* maven repository support
* build support for eclipse project generation
* ivy based build

Changes in contrib:
* zookeeper-tree: export/import znode namespace
* zooinspector: gui browser for znode namespace
* bookkeeper client rewrite, use of netty
