+0.5.0
+-----------
+- redis_failover is now built on top of ZooKeeper! This means redis_failover enjoys all of the reliability, redundancy, and data consistency offered by ZooKeeper. The old fragile HTTP-based approach has been removed and will no longer be supported in favor of ZooKeeper. This does mean that in order to use redis_failover, you must have ZooKeeper installed and running. Please see the README for steps on how to do this if you don't already have ZooKeeper running in your production environment.

 - No longer force newly available slaves to master if already slaves of that master
 - Honor a node's slave-serve-stale-data configuration option; do not mark a sync-with-master-in-progress slave as available if its slave-serve-stale-data is disabled
 - Change reachable/unreachable wording to available/unavailable
