Every branch of Enterprise Linux is supported with updated for 7 years
... that is the purpose of Enterprise Linux.  This is as compared to the
standard Linux distributions that usually have 1 year (current and last
version ... release every 6 months).

More info here for the upstream ... CentOS mirrors all but the "Extended

(CentOS would also mirror the Extended Life Cycle, but we can not get
the SRPMS from the upstream provider)
