Percona is glad to announce the release of Percona Server 5.6.20-68.0 on August 29, 2014. Download the latest version from the Percona web site or from the Percona Software Repositories.

Based on MySQL 5.6.20, including all the bug fixes in it, Percona Server 5.6.20-68.0 is the current GA release in the Percona Server 5.6 series. All of Percona’s software is open-source and free. Complete details of this release can be found in the 5.6.20-68.0 milestone on Launchpad.

New Features:

• Percona Server has implemented the MySQL 5.7 SHOW SLAVE STATUS NONBLOCKING syntax for Lock-Free SHOW SLAVE STATUS feature. The existing SHOW SLAVE STATUS NOLOCK is kept as a deprecated alias and will be removed in Percona Server 5.7. There were no functional changes for the feature.
• Percona Server Audit Log Plugin now supports JSON and CSV formats. The format choice is controlled by audit_log_format variable.
• Percona Server Audit Log Plugin now supports streaming the audit log to syslog.
• TokuDB storage engine package has been updated to version 7.1.8.

Bugs Fixed:

• Querying INNODB_CHANGED_PAGES table with a range condition START_LSN > x AND END_LSN #1202252 (Jan Lindström and Sergei Petrunia).
• SQL statements of other connections were missing in the output of SHOW ENGINE INNODB STATUS, in LATEST DETECTED DEADLOCK and TRANSACTIONS sections. This bug was introduced by Statement Timeout patch in Percona Server 5.6.13-61.0. Bug fixed #1328824.
• Some of TokuDB distribution files were missing in the TokuDB binary tarball. Bug fixed #1338945.
• With XtraDB changed page tracking feature enabled, queries from the INNODB_CHANGED_PAGES could read the bitmap data whose write was in still progress. This would cause the query to fail with an ER_CANT_FIND_SYSTEM_REC and a warning printed to the server error log. The workaround has been to add an appropriate END_LSN-limiting condition to the query. Bug fixed #1193332.
• mysqld-debug was missing from Debian packages. This regression was introduced in Percona Server
