 * The `InputManager.onTouchMove` function has been fixed so it now correctly handles touch events on pages that have scrolled horizontally or vertically and shifted the viewport. Fix #6489 (thanks @somechris @hyewonjo)
 * `Factory.staticBody`  had the wrong return type in the docs/TS defs. Fix #6693 (thanks @ddhaiby)
+* The `Time.Timeline` class didn't show as extending the Event Emitter, or have `config` as an optional argument in the docs / TS defs. Fix #6673 (thanks @ghclark2)
