This week has been intense (260+ commits from 36 authors). I have made a major cleanup of tickets and pull requests on the Symfony Github account: 120+ tickets and 90+ pull requests have been closed and all remaining tickets and pull requests are now properly tagged. Bernhard has also worked really hard on the Form and the Validator components. That gives us a much better picture of the state of Symfony 2.1.
That why I'm really happy to release the third beta of Symfony 2.1 today and quite confident that this is the last beta version before entering the release candidate phase.
If you have already upgraded to beta2, have a look at the changes you need to make to upgrade to beta3.
