The version on GNU ELPA (http://elpa.gnu.org/packages/org.html ), which
is labeled org-20161024, is org-git-version 8.3.6-7-g4d7d52-elpa.
I believe that indicates that it is the latest version from the stable
maint branch, not a version from the unstable master branch (which is at
8.3.6-1264-g21932c right now).
