[MariaDB 10.2](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) is the previous stable series of MariaDB. It is an evolution\
of [MariaDB 10.1](/docs/release-notes/community-server/old-releases/10.1/changes-improvements-in-mariadb-10-1.md) with several entirely new features not found anywhere else\
and with backported and reimplemented features from MySQL 5.6 and 5.7.

[MariaDB 10.2.25](/docs/release-notes/community-server/old-releases/10.2/10.2.25.md) is a [***Stable (GA)***](/docs/release-notes/community-server/about/release-criteria.md) release.

**For an overview of** [**MariaDB 10.2**](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) **see the**[**What is MariaDB 10.2?**](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) **page.**

Upgrading from earlier 10.2.x versions is **highly recommended** for all**Galera** users due to bug [MDEV-12837](https://jira.mariadb.org/browse/MDEV-12837) which caused serious stability issues\
with earlier versions. See the bug issue page for more information.

Thanks, and enjoy MariaDB!
