Want to upgrade to this new release? Because Symfony protects backwards-compatibility very closely, this should be quite easy. Use SymfonyInsight upgrade reports to detect the code you will need to change in your project and read our upgrade documentation to learn more.

Want to be notified whenever a new Symfony release is published? Or when a version is not maintained anymore? Or only when a security issue is fixed? Consider subscribing to the Symfony Roadmap Notifications.

Help the Symfony project!

As with any Open-Source project, contributing code or documentation is the most common way to help, but we also have a wide range of sponsoring opportunities.
