+0.9.0
+-----------
+- Make Node Manager's lock path vary with its main znode. (Bira)
+- Node Manager's znode for holding current list of redis nodes is no longer ephemeral. This is unnecessary since the current master should only be changed by redis_failover.
+- Introduce :master_only option for RedisFailover::Client (disabled by default). This option configures the client to direct all read/write operations to the master.
+- Introduce :safe_mode option (enabled by default). This option configures the client to purge its redis clients when a ZK session expires or when the client hasn't recently heard from the node manager.
+- Introduce RedisFailover::Client#on_node_change callback notification for when the currently known list of master/slave redis nodes changes.
+- Added #current_master and #current_slaves to RedisFailover::Client. This is useful for programmatically doing things based on the current master/slaves.
+- redis_node_manager should start if no redis servers are available (#29)
+- Better handling of ZK session expirations in Node Manager.
