Does Mage-OS 2.x run on PHP 8.1?
NoNone of the 6 Mage-OS 2.x releases we tested install on PHP 8.1. The product's Composer constraints do not allow this PHP version. The newest Mage-OS release that installs on PHP 8.1 is 1.0.6. Mage-OS lists PHP 8.4 for 2.3.0.
Last run 4 October 2026. Each run is the stack Mage-OS recommends for the release with only the php swapped for PHP 8.1, installed in Docker, compiled and put through storefront, checkout and admin browser tests.
