Centos commands: Yum Upgrade versus Yum update

Hi,

I would like to know the difference between YUM UPDATE and YUM UPGRADE. The man pages say upgrade is same as update with the obsolete option. And by default it says the obsolete option is turned on, which would make them equivalent. Does not say what obsolete does.

Can someone please clarify?
