Is there a revision history anywhere, detailing when the Web developer edition of HTML Living Standard at http://developers.whatwg.com is updated and with what updates? It is a very useful resource, but uncertainty on how up to date it is diminish it somewhat.
I see, for instance, that it does not mention the main element at all, whereas the specification does < http://www.whatwg.org/specs/web-apps/current-work/multipage/grouping-content.html#the-main-element >.
