In case you missed it (like I did), the Symfony 1.2 Release Candidate is now available:
Being a release candidate now means that we are no longer doing any changes besides bug fixing and documentation, lots of documentation. Of course with very good reason we do an exception but generally that’s it. This means that you will also have no problems upgrading from this release candidate to the final version. If you haven’t tried 1.2 yet because you were afraid of such changes, you no longer have an excuse.
