Symfony 2.1.0 released

Warning: Symfony 2.1 is no longer supported. Consider upgrading your applications to the most recent Symfony version.

I'm very happy to announce the immediate availability of Symfony 2.1.0.

Since the release of Symfony 2.0, the Symfony community has been hard at work. We've merged more than 1,100 pull requests for Symfony 2.1 (3,500+ commits), and more than 6,000 unit tests have been added. The documentation has also improved a lot and more than 3,000 new lines of documentation have been added.

Symfony2 has been used in production on very large websites for more than 2 years now, and the new Symfony 2.1 brings even more stability and nice features.

If you have not tried to upgrade yet, first read the UPGRADE file that comes with Symfony Standard Edition, then the UPGRADE file that comes with Symfony.

After upgrading, run the web/config.php script from your browser and the app/check.php script from the CLI to check if your PHP environment is setup properly.

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.

Awesome! Been looking forward to this for quite some time. Composer was a spectacular move, and will (hopefully) help to bring the PHP community together with dependency injection across any application, regardless of framework used.
