Thank you all for your replies.
I am a developer trying to setup a dev-environment, and I was just looking to get the latest version available so that I can take advantage of the new drivers available with cinder. 
Followed the steps mentioned above and I could get the installed openstack/cinder packages upgraded to Icehouse, which seems to work fine for my purposes.

One more addendum. I just noticed you asked for the "latest supported
version." For that, you will want Red Hat Enterprise Linux OpenStack
Platform, instead of RDO, which is the community version of OpenStack
that Tim Bell pointed to.

The supported version based on Juno will be available on Scientific
Linux 6.5 as soon as it's released. The community version based on Juno
will require 7, unless significant community effort is put in to make it
work on 6.5 (which may not happen).

Here is the URL for the supported version:
