this http stuff get really old. I'm sure that this is yet another 'fixed on Github but doc web pages can't yet be updated for a bunch of really good reasons'. Replace http by https and this should go away.
Actually my constructive comment to the update doc problem has been to allow people to comment on the docs page so that people not versed into github/jenkins/roboto/coster/henry/go and I certainly miss some tool or the other to provide useful corrections. It does not fit into your way. So be it. But I have no intention to get sucked in this maelstrom.
