Which PHP versions does Mage-OS 3.x support?
Every Mage-OS 3.x release we tested installs on PHP 8.3, 8.4 and 8.5. None install on PHP 7.4, 8.1 or 8.2.
Last run 15 October 2026. Each run is our baseline stack for the release, picked from Mage-OS's system requirements, with only the php swapped, installed in Docker, compiled and put through storefront, checkout and admin browser tests.
