This is not anything "official," but for whatever it may be worth, I have been in the habit of tracking head and recent stable branches on a couple of machines on a daily basis, and part of that process for the last few years has been to update some files that may be found at http://www.catwhisker.org/~david/FreeBSD/history/ In particular, http://www.catwhisker.org/~david/FreeBSD/history/laptop_uname_amd64.13.txt shows the revisions that worked for me on my laptop; http://www.catwhisker.org/~david/FreeBSD/history/freebeast_uname_amd64.13.t= xt shows the same for a headless "build machine."
