**Release date:** 23 May 2013

This is a [***Stable***](/docs/release-notes/community-server/about/release-criteria.md) ***(GA)*** release. In general this\
means that there are no known serious bugs, except for those marked as feature\
requests, that no bugs were fixed since last release that caused a notable code\
changes, and that we believe the code is ready for general usage (based on bug\
inflow).

In most respects [MariaDB](https://github.com/mariadb-corporation/docs-release-notes/blob/test/kb/en/mariadb/README.md) will work exactly as MySQL: all commands,\
interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.

This is primarily a bug-fix release.

## Ubuntu 13.04 "Raring" Packages

Packages are now available for Ubuntu 13.04 "Raring". Use the [repository configuration tool](https://downloads.mariadb.org/mariadb/repositories/) to get the appropriate commands.

## Ubuntu 8.04 LTS "Hardy" and 11.10 "Oneiric" Deprecated

In accordance with the [MariaDB Deprecation Policy](/docs/release-notes/community-server/about/platform-deprecation-policy.md) the following distributions have reached the end of their support periods (EOL):

* Ubuntu 8.04 LTS "Hardy"
* Ubuntu 11.10 "Oneiric"
* Mint 9 LTS "Isadora"
* Mint 12 "Lisa"

This release ([MariaDB 5.5.31](/docs/release-notes/community-server/old-releases/5.5/5.5.31.md)) is therefore the last MariaDB release to feature packages for these distros. The [repositories](https://downloads.mariadb.org/mariadb/repositories/) for them will remain online until the 5.5.32 release. At that time they will go away.

Binary tar.gz files built on Ubuntu "Hardy" will also be going away. These are the ones that *do not* require GLIBC\_2.14+. So for the next release, all binary tar.gz files for Linux will require GLIBC\_2.14+.

Thanks, and enjoy MariaDB!
