Hi,

On about 8am GMT Jan 18, my server reported an unusually large number of yum updates available.

I think this is due to the release of CentOS 5.9:

However, I just wanted to be a little paranoid, since this is unusual for my normal yum update reports (over 100 updates compared to a couple a week).  Can someone confirm my suspicion, or is it possible I have a security issue on my hands?

Thank you!!!!
