New Features:

Bugs Fixed:

  • Values of IP and DB fields in the Audit Log Plugin were incorrect. Bug fixed #1379023.
  • Specifying the --malloc-lib during the server start would produce two LD_PRELOAD entries, if a system-wide jemalloc library was installed. Bug fixed #1382069.
  • In multi-threaded slave replication setup, an incomplete log event group (the one which doesn’t end with COMMIT/ROLLBACK/XID) in a relay log could have caused a replication stall. An incomplete log event group might occur as a result of one of the following events: 1) slave crash; 2) STOP SLAVE or FLUSH LOGS command issued at a specific moment; 3) server shutdown at a specific moment. Bug fixed #1331586 (upstream #73066).
  • Purging bitmaps exactly up to the last tracked LSN would abort XtraDB changed page tracking. Bug fixed #1382336.
  • mysql_install_db script would silently ignore any mysqld startup failures. Bug fixed #1382782 (upstream #74440).

Other bugs fixed: #1369950, #1335590, #1067103, and #1282599.

UPDATE [2014-11-14]: Bug #1390695 caused Percona Server 5.6.21-70.0 to crash on data import on Ubuntu Utopic (14.10). This bug has been fixed and packages for Ubuntu Utopic have been updated.
