The joint effort of the W3C HTML WG and WHATWG resulted in publication of two documents in the W3C Technical Report space: HTML 5 and HTML 5 differences from HTML 4. I think I can safely say that the WHATWG community is very happy with the W3C publishing HTML 5 as a First Public Working Draft. Many thanks to all involved!

Some cool elements there like <dialog>, <command>, <meter> and being able to do things like input type=”datetime|datetime-local|date|month|week|time|number|range|email|url”.
