# System Variables Added in MariaDB 5.5

This is a list of [system variables](/docs/server/server-management/variables-and-modes/server-system-variables.md) that were added in the [MariaDB 5.5](/docs/release-notes/community-server/old-releases/5.5/changes-improvements-in-mariadb-5-5.md) series.

The list excludes variables related to non-default storage engines and plugins that can be added to [MariaDB 5.5](/docs/release-notes/community-server/old-releases/5.5/changes-improvements-in-mariadb-5-5.md):
