In addition to the security update, MySQL 5.1.47 is also very important for an additional reason. The InnoDB plugin that ships with this version has been updated to 1.0.8, which is considered to be of General Availability (GA) quality.
There are more changes, including some twists to the error log, to make replication administration more robust.
MySQL 5.0.91 security update
Together with MySQl 5.1.47, there is a security update of MySQL 5.0.91.
Since MySQL 5.0 is now in Extended Support state, the binaries are not in the main download pages, but only in the archives. As the MySQL Lifecycle Policy says, only serious security bugs are fixed, and the binaries are provided at the company's discretion.
If you are still using MySQL 5.0, this is a good moment to upgrade to 5.1.
