Percona Server for MySQL 5.6.22-71.0¶
Based on MySQL 5.6.22, including all the bug fixes in it, Percona Server for MySQL 5.6.22-71.0 is the current GA release in the Percona Server for MySQL 5.6 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.6.22-71.0 milestone at Launchpad.
Percona Server for MySQL has implemented improved slow log reporting for queries in stored procedures.
TokuDB storage engine package has been updated to version 7.5.4. Percona Server for MySQL with an older version of TokuDB could hit an early scaling limit when the binary log was enabled. TokuDB 7.5.4 fixes this problem by using the hints supplied by the binary log group commit algorithm to avoid fsync’ing its recovery log during the commit phase of the 2 phase commit algorithm that MySQL uses for transactions when the binary log is enabled.
Debian and Ubuntu init scripts no longer have a hardcoded server startup timeout. This has been done to accommodate situations where server startup takes a very long time, for example, due to a crash recovery or buffer pool dump restore. Bugs fixed #1072538 and #1328262.
A read-write workload on compressed InnoDB tables might have caused an assertion error. Bug fixed #1268656.
A wrong stack size calculation could lead to a server crash when Performance Schema tables were storing big amount of data or in case of server being under highly concurrent load. Bug fixed #1351148 (upstream #73979).
A read-write workload on compressed InnoDB tables might have caused an assertion error. Bug fixed #1395543.

SHOW ENGINE INNODB STATUSwas displaying two identical
TRANSACTIONSsections. Bug fixed #1404565.
