"Un" im unsure off, what you are referring to by that. U5 is Update 5 of ( I presume RHEL 3 ). If you have a look at the CentOS 3 branch, you'll see its at CentOS 3.4 ( meaning Centos 3 with Update 4 ). So to answer your question, these are updates to the initial base install of the OS which provide newer software ( at times ) bug fixes, etc. etc. They are released 3 - 4 times a year per build and centos release them usually shortly after RHEL does so. Update 5 for 3 is in "beta" at the moment. Update 1 for 4 will come, 4's only just been released.
