The W3C DOM Working Group published its final recommendation and subsequently disbanded in 2004. Development efforts migrated to the WHATWG , which continues to maintain a living standard.  In 2009, the Web Applications group reorganized DOM activities at the W3C.  In 2013, due to a lack of progress and the impending release of HTML5 , the DOM Level 4 specification was reassigned to the HTML Working Group to expedite its completion.  Meanwhile, in 2015, the Web Applications group was disbanded and DOM stewardship passed to the Web Platform group.  Beginning with the publication of DOM Level 4 in 2015, the W3C creates new recommendations based on snapshots of the WHATWG standard.
