 *SVN*
 
+* Add document.loaded, a boolean that is set to true once dom:loaded is fired. Setting document.loaded to true before the document is loaded prevents dom:loaded from being fired. [Tobie Langel]
+
 * Make Element#insert standard-compliant. Fixes an issue in FF3b2 when inserting HTML or text inside DOM nodes which aren't (yet) appended to the document. [Tobie Langel]
 
 * Add some missing semicolons to the source tree.  Closes #10659.  [Richard Quadling]
