Which MariaDB, MySQL and Percona versions does Magento 2.4.2 support?
Every Magento 2.4.2 release we tested installs on MariaDB 10.4, MySQL 8.0.46, and Percona 8.0. None install on MariaDB 10.5, 10.6, 10.11, 11.4, 11.8 or 12.3, MySQL 8.4.9 or 9.7, or Percona 8.4.
Last run 3 October 2026. Each run is our baseline stack for the release, picked from Adobe's system requirements, with only the database swapped, installed in Docker, compiled and put through storefront, checkout and admin browser tests.
