Which MariaDB, MySQL and Percona versions does Magento 2.4.4 support?

Every Magento 2.4.4 release we tested installs on MariaDB 10.4, MySQL 8.0.46, and Percona 8.0. MariaDB 10.5 works from 2.4.4-p9 and MariaDB 10.6 works from 2.4.4-p12. None install on MariaDB 10.11, 11.4, 11.8 or 12.3, MySQL 8.4.9 or 9.7, or Percona 8.4. On MariaDB 10.4, 10.5 and 10.6, MySQL 8.0.46, and Percona 8.0, some runs needed an extra step: Composer aliases for broken 2.4.4 package constraints, ACSD-59280: ReflectionUnionType::getName() error and ACSD-46815: static content deploy fails with the compact strategy.

Last run 5 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.
