Team Foundation Server (TFS) 15 RC2 is available and ready for production use

We have now released TFS "15" RC2. We are using it in production internally. It is fully supported for production use. You can upgrade from TFS 2012 or newer to RC2. You can also upgrade the RC1 release to RC2, and you will be able to upgrade from RC2 to RTM (that should be a very fast upgrade, since there will be very few changes between RC2 and RTM).
