Data Sources
The raw data for this chart is based on the official “Requirements” page in WordPress.org.
In addition, since WordPress 2.9 the required MySQL version for each WordPress version is defined in version.php file.
History
WordPress 2.0 was the first version to set minimum required MySQL version – it was decided to use MySQL 3.23.23.
Two years later, on January 2007, WordPress 2.1 was released with upgraded minimum required MySQL version – adopting MySQL 4.0.
After three more years, on December 2009, WordPress 2.9 was released with new minimum required MySQL version – this time is was MySQL 4.1.2 [ Source ]. In this version the required PHP and MySQL versions added to version.php file.
In mid 2010, the development team announced that as of WordPress 3.2, it will no longer support PHP 4 and MySQL 4 [ Source ]. When 3.2 was released on July 2011, the new minimum required version was MySQL 5.0.15 [ Source ].
The recommended version is MySQL 5.6 or greater [ Source ].
