Symfony 6.4, PHP 8.4 and less legacy code establish a modern technical foundation for the PrestaShop ecosystem.

June 2025 marked a historic milestone for the open-source community with the official release of PrestaShop 9.0.
This isn’t just another version number; this release represents the culmination of years of refactoring efforts to modernize the platform’s core architecture. As PrestaShop experts, we’ve analyzed the code in depth, and the verdict is clear: version 9.0 is the most stable, fastest, and most secure foundation ever built for this CMS. By definitively adopting Symfony 6.4 and supporting PHP 8.4, it eliminates the technical debt carried over from previous versions. For retailers, this translates into a noticeably more agile back office and a front end optimized for Core Web Vitals right out of the box. However, a major leap involves significant changes in module compatibility.
Therefore, having a specialized PrestaShop Maintenance plan is essential during the transition period to ensure that custom developments and critical integrations continue to function seamlessly in this new, strict, and robust environment.
New robust architecture for the digital future
The main new feature of PrestaShop 9.0 is the almost complete elimination of legacy code based on its own outdated framework. Now, the logic relies heavily on standard Symfony components, making the software much more attractive to professional developers and easier to maintain in the long run. This standardization facilitates the creation of complex functionalities and API connections without «reinventing the wheel.» For store owners still operating on versions 1.7 or 8.1, the release of 9.0 starts the countdown to Update PrestaShop.
Postponing this migration means remaining on a technology that will soon stop receiving security patches. Furthermore, the new version introduces the «Hummingbird» theme as the standard, designed specifically for mobile accessibility and speed, retiring the old «Classic» theme, which was already insufficient for current SEO and UX requirements.
"PrestaShop 9.0 is not an option, it's the new standard. Ignoring this update means condemning your store to technical obsolescence, losing speed, security, and the ability to compete against modern platforms on equal terms."
Migrating to version 9.0 is complex and requires a rigorous audit. We do not recommend automatic updates without backups. Our team manages the entire process in a test environment, ensuring that data and design are seamlessly transferred to the new engine before going live.
