Can't upgrade from TC to Release

[Felix Miata]

I have a 17 installation last upgraded May 4 that I tried to upgrade to 17 
release last night, and again this AM. It won't do it because Yum is looking 
to fedora/development/17 instead of fedora/releases/17. Yum produces about 
two screens of 404 mirror errors, then fails anything requiring mirror 
access. Viewing /etc/yum/repos.d/fedora.repo I can't see any reason why it 
would be doing that. I see there:

[fedora]
name=Fedora $releasever - $basearch
failovermethod=priority
#baseurl=http://download.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything/$basearch/os/
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch
enabled=1
metadata_expire=7d
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

What can I do to fix the installation so Yum works again?

FWIW, the installation was originally made from 
mirrors.us.kernel.org/fedora/development/17, and fedora-release-rawhide is 
not installed, while fedora-release-17.1.noarch is.
