Yeah, but I'd call that a minor release. RHEL 7 has been out since June of 2014.

And if you need major feature updates, like those between OpenSSH 4.3
(the RHEL 5 standard) and OpenSSH 5.3 (the RHEL 6 standard version)
and OpenSSH 6.4 (the RHEL 7 version), well, eventually, backporting
becomes infeasible.

The big problem with the current OpenSSH 6.7p1 release and RHEL 5 is
the out of date OpenSSL library. There are some fascinating checks for
the version number that reject the OpenSSL in RHEL 5, even if it's the
RHEL version with various useful patches backported by Red Hat. The
work of resolving that sort of dependency accumulates, and eventually
become *much* easier just to update the OS rather than maintain the
patches and build trees.

Been there, done that, publish at
