Please excuse my ignorance, since I have not used any RedHat (enterprise or otherwise) until Fedora FC3 (a few weeks) and now CentOS4 (permanently). I keep finding references to Un (I believe it's up to U5 now) in references to bugfixes, etc for RHEL. I presume (?) these are dot releases after the initial release?
Is there anything equivalent for CentOS, or is this RedHat only behavior?
TIA,
