MySQL/Galera 0.8.1 发布，MySQL分支版本

Galera 是一套在 MySQL InnoDB 上面实现 Multi-master 且 synchronous replication 的系統。

Changes: This is a major update over 0.7. Changes include improved flow control, parallel applying, configurability, scriptable state transfer, and notifications. The 0.8 series is protocol incompatible with 0.7 but retains most of the configuration options
