Yes, I think so. master-fedoraproject is the one the site uses now.
You may find that from here:

Hi,
In this project, it seems that there are two components for
fedoraproject.org, which are f12-beta-fedoraproject and
master-fedoraproject.
I am assuming that the first one of f-12-beta-fedoraproject should be
translated for Fedora 12.
Could you someone please clarify this for me?
