On April 8, 2025 Adobe released Magento Open Source and Adobe Commerce 2.4.8. It is not a cosmetic patch: the release moves the whole platform to current versions of PHP, databases and search. If your store runs 2.4.5–2.4.7, now is the time to plan the move.
Release highlights
- PHP 8.4. The new PHP version is supported and PHP 8.1 is dropped, so servers on 8.1 have to be upgraded along with the platform.
- OpenSearch 2.19. Catalog search moves to a fresh OpenSearch branch. Check any Elasticsearch-specific configuration in advance.
- MySQL 8.4 and MariaDB 11.4. Both are LTS releases you can comfortably run for several years.
- Hundreds of fixes for security, performance and compatibility accumulated since the previous release.
Why not to wait
Every Magento version has a support window, after which security patches stop. A store on an outdated version carries a breach risk, and it also runs into trouble with PCI DSS, payment modules and hosts that gradually phase out old PHP versions.
How we plan the upgrade
- Audit. We list third-party modules and custom code and check their PHP 8.4 compatibility.
- Environment. We spin up a copy of the store on the new stack: PHP 8.4, OpenSearch 2.19, MySQL 8.4.
- Upgrade and fixes. We update the core with Composer and fix deprecated calls and incompatible modules.
- Testing. We run the key flows: catalog, search, cart, checkout, payments and ERP integrations.
- Release. We switch over in a low-traffic window with a rollback plan ready.
For a typical store with 20–40 modules this takes 2–4 weeks. Want an estimate for your project? Get in touch and we will run a compatibility audit.
