Based on MySQL 5.6.27, including all the bug fixes in it, Percona Server for MySQL 5.6.27-75.0 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 5.6.27-75.0 milestone at Launchpad.
Percona Server for MySQL is now available for Ubuntu 15.10 (Wily).
TokuDB MTR tests have been integrated into Percona Server for MySQL.
Linux thread ID is now available in the
Percona Server for MySQL has now re-enabled savepoints in triggers and stored functions.
Fixed transactional inconsistency with rollback in TokuDB. Rolling back a large transaction with many inserts/updates/deletes could result in some of the changes being committed rather than rolled back. Bug fixed #1512455.
TokuDB could crash under load if transaction-isolation level
READ-COMMITTEDwas used. Bug fixed #1501633.
TokuDB thread pool names were missing in the
SHOW ENGINE tokudb STATUSwhich caused duplicate entries. Bug fixed #1512452.
innodb_track_redo_log_nowvariable dynamically would crash the server if it was started without
innodb_track_changed_pagesenabled. This variable is available on debug builds only. Bug fixed #1368530.
If the user had duplicate pid-file options in config files when running
yum upgrade, the upgrade would stop with error because it would think it found the duplicate pid while it was the same pid specified twice. Bug fixed #1454917.
An online DDL operation could have caused server crash with fake changes enabled. Bug fixed #1226532.
Fixed the conflicting meta packages between 5.1, 5.5, and 5.6 release series in Debian and Ubuntu distributions.
percona-server-clientmeta packages now point to the latest 5.6 release. Bug fixed #1292517.
innodb_fake_changesvariable value in the middle of a transaction would have an immediate effect, that is, making part of the transaction run with fake changes enabled and the rest with fake changes disabled, resulting in a broken transaction. Fixed by making any
innodb_fake_changesvalue changes becoming effective at the start of the next transaction instead of the next statement. Bug fixed #1395579.
Startup would fail due to a small hard-coded timeout value in the init script for the pid file to appear. This has been fixed by creating default file for Debian init script timeout parameters in
etc/default/mysql. Bug fixed #1434022.
tokudb-backup-pluginwas missing Valgrind dependency. Bug fixed #1494283.
Percona Server for MySQL would fail to install on CentOS 7 if
mariadb-develpackage was already installed. Bug fixed #1499721.
Fixed multiple TokuDB clang build issues. Bug fixed #1512449.
