Which PHP versions does Mage-OS 1.x support?
Every Mage-OS 1.x release we tested installs on PHP 8.2. PHP 8.1 works up to 1.0.6, PHP 8.3 works from 1.0.2 and PHP 8.4 works from 1.1.0. None install on PHP 7.4 or 8.5. On PHP 8.4, some runs needed an extra step: PHP 8.4 implicit-nullable deprecation stops setup:di:compile.
Last run 5 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.
