It is an evolution of [MariaDB 10.9](/docs/release-notes/community-server/old-releases/10.9/what-is-mariadb-109.md) with several entirely new features. [MariaDB 10.10.0](/docs/release-notes/community-server/old-releases/10.10/10.10.0.md) is not a single release, but is instead a number of preview releases based on feature branches. Each should be considered [***Alpha***](/docs/release-notes/community-server/about/release-criteria.md). **For an overview of** [**MariaDB 10.10**](/docs/release-notes/community-server/old-releases/10.10/what-is-mariadb-1010.md) **see the**[**What is MariaDB 10.10?**](/docs/release-notes/community-server/old-releases/10.10/what-is-mariadb-1010.md) **page.** Thanks, and enjoy MariaDB!
