**Release date:** 22 Sep 2011

[MariaDB 5.2.9](/docs/release-notes/community-server/old-releases/5.2/5.2.9.md) is a [Stable release](/docs/release-notes/community-server/about/release-criteria.md).In general this means there are no known serious bugs and we believe the code is ready for general usage. A "stable" MariaDB release is equivalent to a MySQL "GA" release.

**For a detailed description of** [**MariaDB 5.2**](/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2.md) **see the** [**What is MariaDB 5.2**](/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2.md) **page.**

Compared to [MariaDB 5.2.8](/docs/release-notes/community-server/old-releases/5.2/5.2.8.md), [MariaDB 5.2.9](/docs/release-notes/community-server/old-releases/5.2/5.2.9.md) is a bug-fix release.

For a list of every change made in [MariaDB 5.2.9](/docs/release-notes/community-server/old-releases/5.2/5.2.9.md), with links to detailed information on each push, see the [MariaDB 5.2.9 Changelog](/docs/release-notes/community-server/changelogs/changelogs-mariadb-52-series/mariadb-529-changelog.md).

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.

#### 2 Nov 2011 Update:

We've updated the Ubuntu packages for [MariaDB 5.2.9](/docs/release-notes/community-server/old-releases/5.2/5.2.9.md). Apart from now including packages for Ubuntu 11.10 "Oneiric" the only other change is to remove the default apparmor profile.

Ubuntu 11.10 "Oneiric" introduced some significant [directory changes](https://askubuntu.com/questions/57297/why-has-var-run-been-migrated-to-run).\
Rather than try to keep our apparmor profile in sync with Ubuntu and risk a future breakage when they decide to change something else, we have decided to include an empty profile in our packages. If you have customized your`/etc/apparmor.d/usr.sbin.mysqld` file you will be given the option to keep or remove it during the upgrade. If you haven't customized the default profile, the profile will be removed.
