- Speed improvements (about 4x on flush phase) - Memory improvements (uses no function closures) - Break $eval into $apply, $dispatch, $flush - Introduced $watch and $observe Breaks angular.equals() use === instead of == Breaks angular.scope() does not take parent as first argument Breaks scope.$watch() takes scope as first argument Breaks scope.$set(), scope.$get are removed Breaks scope.$config is removed Breaks $route.onChange callback has not "this" bounded
