Hi.
Thanks for your interest. We are working on it, but we can't add 7.0 RC1 to Fedora. The RC 1 release contains prebuilts and other binaries that are not really allowed in Fedora. I have been told that this should get fixed in RC 2 timeframe, so we can hopefully pick that up and build/package that into Fedora.
