Does Magento 2.4.5 run on PHP 8.5?
NoNone of the 15 Magento 2.4.5 releases we tested install on PHP 8.5. The product's Composer constraints do not allow this PHP version. The newest Magento release that installs on PHP 8.5 is 2.4.9. Adobe lists PHP 8.1 for 2.4.5-p14.
Last run 2 October 2026. Each run is the stack Adobe recommends for the release with only the php swapped for PHP 8.5, installed in Docker, compiled and put through storefront, checkout and admin browser tests.
