Percona is glad to announce the release of Percona Server for MySQL 5.6.22-72.0 on February 6th, 2015 (Downloads are available here and from the Percona Software Repositories).

Based on MySQL 5.6.22, including all the bug fixes in it, Percona Server for MySQL 5.6.22-72.0 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 5.6.22-72.0 milestone at Launchpad.

New Features

Percona Server for MySQL is now able to log the query’s response times into separate READ and WRITE INFORMATION_SCHEMA tables. Two new INFORMATION_SCHEMA tables QUERY_RESPONSE_TIME_READ and QUERY_RESPONSE_TIME_WRITE have been implemented for READ and WRITE queries correspondingly.

New ps_tokudb_admin script has been implemented to make the TokuDB Storage engine installation easier.

Percona Server for MySQL now supports Online GTID deployment. This enables GTID to be deployed on existing replication setups without making the master read-only and stopping all the slaves. This feature was ported from the Facebook branch.

Bugs Fixed

SET STATEMENT ... FOR <statement> would crash the server if it could not execute the <statement> due to: 1) if the <statement> was Read-Write in a Read-Only transaction (bug #1387951), 2) if the <statement> needed to re-open an already open temporary table and would fail to do so (bug #1412423), 3) if the <statement> needed to commit implicitly the ongoing transaction and the implicit commit would fail (bug #1418049).

TokuDB storage engine would fail to load after the upgrade on CentOS 5 and 6. Bug fixed #1413956.

Fixed a potential low-probability crash in XtraDB linear read-ahead code. Bug fixed #1417953.

Setting the max_statement_time per query had no effect. Bug fixed #1376934.

Other bugs fixed: #1407941, #1415843 (upstream #75642).
