The short of it
Openstack Newton was packaged early last week (when rc2 was still going on upstream) and the tags for the major projects were packaged the day they released (nova and the like).
I've updated the openstack-meta package to 2016.2.9999 and would recommend people use that.
Heat has also been packaged this time around so you are able to use that if you wish.
I'll link to my keywords and use files so you may use them if you wish as well. Please keep in mind that my use file is for my personal setup (static kernel, vxlan/linuxbridge and postgresql)
