* Thu Jul 12 2018 Alfredo Moralejo <firstname.lastname@example.org> - 2.1.4-3 - Update patch "Don't send AAAA DNS request when domain resolved to IPv4" to merged version
I've rebased for osp14 in bug 1607963, we can tag that same build back for 13/12. Also we can rebase RDO to the same thing. I tested it on osp13 and everything looks fine to me.
