Old MySQL Versions

MariaDB 5.1 was the first release of MariaDB. It was based on MySQL 5.1.

In a sense, users can think about MySQL 5.0 and older releases (or even older releases of the MySQL 5.1 tree) as old versions of MariaDB.

This page lists the main features that were added in very old MySQL trees, before MariaDB was created. This is done for historical purpose, and can also be useful for users who still run those versions.
