[CentOS] 5.1 Upgrade Not Working?

So both "yum upgrade" and "yum update" now are complete and there's no
new packages.  However, when I attempt to check my version, I'm still
showing 5.

# cat /etc/redhat-release
CentOS release 5 (Final)

I remember seeing 5.1 repositories being access for the upgrades.  Is
it possible my system did not upgrade?

# uname -r
2.6.18-53.1.4.el5.centos.plus

Thanks,
Scott
