In December 2021, MariaDB announced its new release model: quarterly releases with a one-year maintenance period of each release. MariaDB 10.6 is the last database version that falls under the old release model and has a five-year maintenance period (long-term support).
Taking into account the MariaDB release model, Plesk announces its policy regarding MariaDB support:
- (MariaDB 10.6 and earlier) Plesk supports each version of MariaDB as a local database server for five years after a MariaDB release.
- (MariaDB 10.7 and later) Plesk supports each stable version of MariaDB as a remote database server. Plesk introduces the support within one month after a stable MariaDB release.
As a local database server, we recommend that you install a long-term support release (LTS release) of MariaDB. At the moment, LTS releases are MariaDB 10.6 and earlier. If MariaDB has other LTS releases in the future, Plesk will support them as a local database server as well.
Note: The support also applies to subsequent Plesk updates and to Plesk installation on a server with MariaDB already installed from the OS or MariaDB repository.
Note: It means that the Plesk administrator can register MariaDB in Plesk (Tools & Settings > Database Servers (under "Applications & Databases")) and then use MariaDB to host users' databases.
