"Red Hat Enterprise Linux 6 (RHEL) was officially released in
November of 2010. Since then, Red Hat has managed to already push
out RHEL 6.1 and migrate a decent book of business to their next
generation Linux platform.
"With the RHEL 6 release now 8 months past, for those that are
looking for a free (as in beer) version of RHEL 6, there has been a
key choice that has lagged behind. CentOS which is a clone of RHEL,
is still pushing out their version of CentOS 6.
As of Friday July 8th, CentOS 6 became available on some of the
mirrors, which means full/final release is soon.
