"Red Hat is out today with the GA release of Red Hat Enterprise
Linux 5.6 (RHEL).
"After the big launch of RHEL 6 last year though, there isn't a
whole lot to be excited about in the latest 5.x release. That said
RHEL 5.x users that aren't in a position to move to RHEL 6 will
likely be very happy with the update."
