Percona Server 5.6.28和5.5.47發布，更新如下：

Bugs 修復:

Clustering secondary index could not be created on a partitioned TokuDB table. Bug fixed #1527730 (DB-720).
When enabled, super-read-only option could break statement-based replication while executing a multi-table update statement on a slave. Bug fixed #1441259.
RunningOPTIMIZE TABLEorALTER TABLEwithout theENGINEclause would silently change table engine if enforce_storage_engine variable was active. This could also result in system tables being changed to incompatible storage engines, breaking server operation. Bug fixed #1488055.
Setting the innodb_sched_priority_purge variable (available only in debug builds) while purge threads were stopped would cause a server crash. Bug fixed #1368552.
Small buffer pool size could cause XtraDB buffer flush thread to spin at 100% CPU. Bug fixed #1433432.
Enabling TokuDB withps_tokudb_adminscript inside the Docker container would cause an error due to insufficient privileges even when running as root. In order for this script to be used inside Docker containers this error has be been changed to a warning that a check is impossible. Bug fixed #1520890.
InnoDB status will start printing negative values for spin rounds per wait, if the wait number, even though being accounted as a signed 64-bit integer, will not fit into a signed 32-bit integer. Bug fixed #1527160 (upstream #79703).

Other bugs fixed: #1384595 (upstream #74579), #1384658 (upstream #74619), #1471141 (upstream #77705), #1179451, #1524763 and #1530102.

Percona 為 MySQL 數據庫服務器進行了改進，在功能和性能上較 MySQL 有著很顯著的提升。該版本提升了在高負載情況下的 InnoDB 的性能、為 DBA 提供一些非常有用的性能診斷工具；另外有更多的參數和命令來控制服務器行為。

Percona Server 只包含 MySQL 的服務器版，并沒有提供相應對 MySQL 的 Connector 和 GUI 工具進行改進。

Percona Server 使用了一些 google-mysql-tools, Proven Scaling, Open Query 對 MySQL 進行改造。
