Note: This page describes features in the source repository for MariaDB 10.2. There are currently no official packages or binaries available for download which contain the features. If you want to try out any of the new features described here you will need to get and compile the code yourself.

MariaDB 10.2 is the current stable series of MariaDB. It is an evolution of MariaDB 10.1 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6 and 5.7.

MariaDB 10.2.18 is a Stable (GA) release.

For an overview of MariaDB 10.2 see the What is MariaDB 10.2? page.

Upgrading from earlier 10.2.x versions is highly recommended for all Galera users due to bug MDEV-12837 which caused serious stability issues with earlier versions. See the bug issue page for more information.

Thanks, and enjoy MariaDB!
