Upgrade to Symfony 7.4

Last updated:
Edit on GitHub

Spryker primarily supports Symfony 7.4 that was released in November 2025. Backward compatibility remains for Symfony 6.4, but support for Symfony 5 was dropped with the spryker/symfony:3.21.0 release.

Avoid old Symfony versions

Although Spryker still supports older versions of Symfony, avoid installing them. Installing older versions of Symfony may cause conflicts with other packages that may have different requirements. Always try to keep your dependencies updated.

Main changes in Symfony 7.4

Symfony 7.4 is a long-term support (LTS) release. The major changes include the following:

  • Symfony 7.4 removes all code deprecated throughout the Symfony 6.x series. For the full list of removed code, see UPGRADE-7.0.md.

  • PHP 8.2 as the minimum required version of PHP.

  • Continued adoption of native PHP attributes over annotations across Symfony components.

  • symfony/monolog-bridge now requires monolog/monolog version 3. Update the Monolog module to version 2.1.0 or later, which widens its monolog/monolog constraint to support version 3:

    composer require spryker/monolog:"^2.1.0"

Read more at CHANGELOG-7.4.

Upgrade Symfony to version 7

To make your project compatible with Symfony 7.4, update the Symfony module and all modules that use it:

composer require spryker/symfony:"^3.21.0"

If you can’t install the required version, check what else you need to update:

composer why-not spryker/symfony:3.21.0

This gives you a list of modules that require the latest spryker/symfony module and that need to be updated as well.

Lock the Symfony version in your project

The spryker/symfony module supports both Symfony 6.4 and Symfony 7.4, so Composer can resolve either version depending on your project’s other dependencies. For more stable and reproducible builds, lock the exact Symfony version your project uses by adding explicit version constraints for the symfony/* packages in your project’s composer.json, for example:

"require": {
    "symfony/console": "7.4.*",
    "symfony/http-kernel": "7.4.*"
}

This prevents Composer from silently switching between Symfony 6.4 and 7.4 when resolving dependencies, and keeps behavior consistent across your team and environments.
