MariaDB 10.2 is the previous 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 10.2.21 is a Stable (GA) release.

For an overview of MariaDB 10.2 see theWhat is MariaDB 10.2? page.
