As of December 31, 2013, Oracle will no longer distribute updates for MySQL 5.1. To facilitate migration from MySQL 5.1 to 5.5 or 5.6, we will continue to support MySQL 5.1 through the life of cPanel & WHM software version 11.42. Of course, we also encourage you to upgrade your version of MySQL sooner if at all possible. Beginning with cPanel & WHM version 11.44, upgrades will require MySQL 5.5 or higher. We expect to release this version in May or June of 2014. To upgrade your version of MySQL, use WHM’s “MySQL Upgrade” interface, which is located at Home >> Software >> MySQL Upgrade. For more information about the upgrade from MySQL 5.1 to 5.5, see Oracle’s documentation or visit MySQL Technical Support.
