Today, at 2pm, after reviewing the test pass results and the status of other exit criteria, the Team Foundation shiproom signed off on the Beta3 bits. We released them to the MSDN operations team who are busily uploading them to the MSDN download center. It takes a day or two to get the bits uploaded and propagated around the world. Once that's done, we’ll turn on the links. In the meantime, as I mentioned last weekend, make sure you’ve downloaded the release candidate of VSTS and the September CTP of SQL.
We can't wait to begin receiving your feedback on this release.
PS: Check out BuckH's blog on Beta3...it's got a lot of good info about the new features available since Beta2.
