Quickly following on the heels of the Symfony 1.3 alpha release, the Symfony blog has announced that the documentation for it has already been published.

I'm proud to announce that both the Practical symfony book (aka the Jobeet tutorial) and the symfony reference guide have been updated to take into account the new features of this version of symfony. For instance, you can start using the new mailer feature of symfony 1.3 by reading day 16 of Jobeet, and learn about all its configuration possibilities by digging through the factories chapter of the reference guide.

Other documentation that's been updated includes the Getting Started guide, the upgrade guide and What's New.
