Breaking: #102518 - Database engine version requirements¶
TYPO3 v13 supports these database products and versions:
MySQL 8.0.17 or higher
MariaDB 10.4.3 or higher
PostgresSQL 10.0 or higher
SQLite 3.8.3 or higher
Environments with older MariaDB or MySQL database engines will reporting an unsupported database version and stop working properly with the upcoming Doctrine DBAL v4 upgrade.
Hosting a TYPO3 instance based on version 13 may require an update of the MariaDB or MySQL database engine.
TYPO3 v12 supports MariaDB 10.4.3 or MySQL 8.0.17 and higher database engines required by v13. This allows upgrading the platform in a first step and upgrading to TYPO3 v13 in a second step.
