In most respects 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 and changelogs, the main differences between MariaDB and MySQL are:

Includes MySQL 5.1.55

For MariaDB 5.1.55 we have merged in all of the upstream changes from MySQL 5.1.54 and 5.1.55. The MySQL 5.1.54 and 5.1.55 release notes have details of what changes were made upstream by MySQL since 5.1.53.

Includes XtraDB 5.1.54-12.5

We have included XtraDB from Percona Server 5.1.54-12.5 in this version of MariaDB. See the Percona Server release notes for what changes were made upstream by Percona.

New Debian and Ubuntu Repositories

For this version of MariaDB we are pleased to announce the availability of Debian and Ubuntu repositories that we will keep up-to-date going forward. The new repositories make use of our world-wide network of MariaDB mirrors and will enable hassle-free upgrades to the latest version of MariaDB as soon as it is released.

See Installing MariaDB .deb Files for information how to setup your Debian or Ubuntu system to use the new repositories.

RPM Package Signing

As part of the new Debian and Ubuntu repositories we have also signed the RPM packages. All RPM package releases going forward will be signed.

New Downloads System

With this version of MariaDB we are also debuting a new MariaDB downloads website. This new site allows you to filter the various files to show only the ones you are interested in and it will attempt to locate the nearest mirror to you based on your IP address.
