[whatwg] Updates to Web developer edition of HTML Living Standard

[Jorge .]

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
>.
