Percona Server 5.5.52-38.3 is now available

Percona announces the release of Percona Server 5.5.52-38.3 on October 5, 2016. Based on MySQL 5.5.52, including all the bug fixes in it, Percona Server 5.5.52-38.3 is now the current stable release in the 5.5 series.

Percona Server is open-source and free. You can find release details of the release in the 5.5.52-38.3 milestone on Launchpad. Downloads are available here and from the Percona Software Repositories.

Bugs Fixed:

• mysql_upgrade now does not binlog its actions by default. To restore the previous behavior, use --write-binlog option. Bug fixed #1065841 (upstream #56155).
• After fixing bug #1540338, system table engine validation check is no longer skipped for tables that don’t have an explicit ENGINE clause in the CREATE TABLE statement. If MySQL upgrade statements are replicated, and the slave does not have the MyISAM set as a default storage engine, then the CREATE TABLE mysql.server statement would attempt to create an InnoDB table and fail because mysql_system_tables.sql script omitted explicit engine setting for this table. Bug fixed #1600056.
• Audit Log Plugin would hang when trying to write a log record of audit_log_buffer_size length. Bug fixed #1588439.
• Audit Log Plugin malformed record could be written after audit_log_flush was set to ON in ASYNC and PERFORMANCE modes. Bug fixed #1613650.
• INFORMATION_SCHEMA.TABLES (or other schema info table) table query running in parallel with INFORMATION_SCHEMA.GLOBAL_TEMPORARY_TABLES query may result in TABLES-query thread context having a mutex locked twice, or unlocked twice, or left locked, resulting in crashes or hangs. Bug fixed #1614849.
