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).
Audit Log Plugin would hang when trying to write a log record of audit_log_buffer_size length. Bug fixed #1588439.
After fixing bug #1540338, system table engine validation check is no longer skipped for tables that don’t have an explicit ENGINE clause in a CREATE TABLE statement. If MySQL upgrade statements are replicated, and 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 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.
