So it's been a long hard slog - see this mini-essay for some details - but we finally have second release candidate for the Fedora 16 Beta. (Yes, you read that right, a release candidate for a Beta: this is not mass-market stuff). If you want to help us ensure the Beta release goes out on time (well, only a week late...), you can download the candidate images and do some of the validation tests: installation, base, and desktop. The individual tests are small and mostly pretty easy to do, and you can a lot of the tests in a virtual machine or (for the desktop tests) from a live image.
If all the required tests for a Beta release pass, we will give this candidate the official QA thumbs-up to go out as the Beta: if not, we'll have to get the bugs fixed and roll a third release candidate. If the test coverage is incomplete, we can't safely sign off on the release. So we really need to get all the tests done!
