In case anyone didn't know, and cares, CentOS 5.3 came out today *looks 
at clock* I mean yesterday.  If you are running 5.2 the upgrade is as 
simple as "yum update".

    

Actually, I think that should be:

# yum upgrade
  

"If you are already running CentOS-5.2 or an older CentOS-5 distro, all 
you need to do is update your machine via yum by running :

'yum update'"
