The Symfony blog has a new post letting you know that the latest version of their guide to the framework - "The Symfony 1.2 Reference Guide" - has been released.

On the symfony blog today there's a new post that points out some of the excellent books you can get covering the framework in general and a bit more specific topics inside.
