How to choose OpenStack (Juno/Kilo/Liberty) for RHEL 7.1

Hi all,

I am trying to deploy OpenStack under RHEL7.1 and don't know how to choose OpenStack version (Juno/Kilo/Liberty). From link https://access.redhat.com/products/red-hat-enterprise-linux-openstack-platform/get-started it seems that I will have OpenStack Kilo but how to get Juno or Liberty.

Thanks.
Kevin
