**Release date:** 10 Sep 2011

[MariaDB 5.3.1](/docs/release-notes/community-server/old-releases/5.3/5.3.1.md) is a [Beta release](/docs/release-notes/community-server/about/release-criteria.md). In general this means that there are no known serious bugs, except for those marked as feature requests. [MariaDB 5.3](/docs/release-notes/community-server/old-releases/5.3/changes-improvements-in-mariadb-5-3.md) radically improves performance for subqueries as well as for joins and single-table queries over large data sets.

Compared to [MariaDB 5.3.0](/docs/release-notes/community-server/old-releases/5.3/5.3.0.md), [MariaDB 5.3.1](/docs/release-notes/community-server/old-releases/5.3/5.3.1.md) is a bug-fix release. It is the second beta release of the 5.3 series and fixes bugs found in the initial 5.3.0 beta release.

For a list of every change made in [MariaDB 5.3.1](/docs/release-notes/community-server/old-releases/5.3/5.3.1.md), with links to detailed information on each push, see the [MariaDB 5.3.1 Changelog](/docs/release-notes/community-server/changelogs/changelogs-mariadb-53-series/mariadb-531-changelog.md). It is worth noting that [MariaDB 5.3](/docs/release-notes/community-server/old-releases/5.3/changes-improvements-in-mariadb-5-3.md) is built on [MariaDB 5.2](/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2.md),[MariaDB 5.1](/docs/release-notes/community-server/old-releases/5.1/changes-improvements-in-mariadb-5-1.md), and MySQL 5.1.

In most respects [MariaDB](https://mariadb.com/docs/server/) will work exactly as MySQL: all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.
