**Release date:** 28 Sep 2010
This is a [[release-criteria|gamma release]]. In general this means we believe the code is ready for general usage (based on bug inflow), but we want more testing before calling it stable. For a list of every change made in this release, see the
[[mariadb-522-changelog|Changelog]]. For a description of this release see the [[what-is-mariadb-51|MariaDB 5.1 overview]].
In most respects [[mariadb|MariaDB]] will work exactly as MySQL: all commands,
interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.
In addition to the differences noted in previous
[[release-notes|release notes]] and
[[changelogs]], the main new things in this version of MariaDB 5.2 are:
== Includes MariaDB 5.1.50
For MariaDB 5.2.2 we have merged in all of the changes from MariaDB 5.1, which included
MariaDB 5.1.50 + some new bug fixes which will be in MariaDB 5.1.51, and MySQL 5.1.51. The [[mariadb-5150-release-notes|MariaDB 5.1.50 release notes]] have details of what changes were made.
== Maria Storage Engine Renamed to Aria
In this version of MariaDB 5.2 the Maria Storage Engine has been renamed to
[[aria-storage-engine|Aria]].
== SphinxSE
The Sphinx Storage Engine has been added to MariaDB. It is built as a dynamically loadable .so plugin, so use it you need to perform a one-time ##[[install-plugin|INSTALL PLUGIN]]##. See the [[sphinx-storage-engine|SphinxSE]] page for more details.
== Bug Fixes
The main drive for this version of MariaDB 5.2 (compared to the previous two
beta releases) was to fix bugs and otherwise prepare for a stable release of
MariaDB 5.2. So, as in [[release-notes|previous releases]], in MariaDB 5.2.2
many bug fixes and other improvements were made. See the
[[mariadb-522-changelog|Changelog]] for details and links to the bugs that were
fixed.
