In 2004, WHATWG (Web Hypertext Application Technology Working Group) was formed. The WHATWG wanted to develop HTML, consistent with how the web was used, while being backward compatible with older versions of HTML.
In 2004 - 2006, the WHATWG gained support by the major browser vendors.
In 2006, W3C announced that they would support WHATWG.
In 2008, the first HTML5 public draft was released.
In 2012, WHATWG and W3C decided on a separation:
WHATWG wanted to develop HTML as a "Living Standard". A living standard is always updated and improved. New features can be added, but old functionality cannot be removed.
The WHATWG HTML5 Living Standard was published in 2012, and is continuously updated.
The W3C HTML5 Recommendation was released 28 October 2014.
The W3C HTML5.1 2nd Edition Recommendation was released 3 October 2017.
