MariaDB logo Version 5.5.23 of MariaDB, a drop-in replacement for MySQL, has been published by the developers at Monty Program. The first stable release in the 5.5 series of the open source database includes performance improvements and "a few added features" over MySQL 5.5.23, which it is based upon.

The developers say that the thread pool feature is now "significantly more efficient", making it comparable to the same closed source feature in MySQL Enterprise. Other changes include a @@skip_replication option and updates to mysql_real_connect(), as well as the addition of a new INSTALL SONAME statement and LIMIT ROWS EXAMINED optimisations.

The developers also note that, as MariaDB 5.5.23 includes MariaDB 5.3.6 from earlier this week, the update fixes a "serious security issue" that could have allowed a user to connect with an invalid password under certain circumstances. Users running older versions are advised to upgrade as soon as possible.

Further details, including a full list of changes, can be found on the What is MariaDB 5.5 page, and in the release notes and change log. MariaDB 5.5.23 is available to download as GPLv2-licensed source and binaries for 32- and 64-bit systems.
