How do I install an RC?

I can’t seem to find instructions for installing an RC. Specifically, I need to upgrade from 9.x to 10.0 RC to use the latest import/export, because there have been breaking changes.

I don’t see any RC packages in the repository (unless I’m searching incorrectly).

$ yum list gitlab*

Do I have to install from source? I’m also OK waiting for the release, which seems like it might happen soon.
