* 'cancelRequestAnimationFrame' renamed to 'cancelAnimationFrame' to reflect an update to the W3C Animation-Timing Spec. (Paul Irish)

In 'utils.js':

if (!window.cancelRequestAnimationFrame) {
  window.cancelRequestAnimationFrame = (window.cancelAnimationFrame ||
                                        window.webkitCancelRequestAnimationFrame ||
                                        window.mozCancelRequestAnimationFrame ||
                                        window.msCancelRequestAnimationFrame ||
                                        window.oCancelRequestAnimationFrame ||
                                        window.clearTimeout);
}

Is now:

if (!window.cancelAnimationFrame) {
  window.cancelAnimationFrame = (window.cancelRequestAnimationFrame ||
                                 window.webkitCancelAnimationFrame || window.webkitCancelRequestAnimationFrame ||
                                 window.mozCancelAnimationFrame || window.mozCancelRequestAnimationFrame ||
                                 window.msCancelAnimationFrame || window.msCancelRequestAnimationFrame ||
                                 window.oCancelAnimationFrame || window.oCancelRequestAnimationFrame ||
                                 window.clearTimeout);
}


In Chapter 8, Excercise '03-easing-off.html', drawFrame function:

window.cancelRequestAnimationFrame(animRequest);

Is now:

window.cancelAnimationFrame(animRequest);
