If you've been using Symfony2 for some time, you probably knew Symfony2bundles.
We've launched this service back in June 2010 to list all Symfony2 bundles - yes, hence the name.
We've changed its name to comply with the Symfony trademark policy.
Symfony2bundles is now KnpBundles!
More details about Symfony2bundles are availables on knplabs.com.
