One of the cool features of the old Bootstrap was the ability to mark content so that it only appeared in certain devices. That remains in the new version, but the class names have changed. And that's really important because you'll have to modify all your classes if you upgrade. So instead of using classes like visible phone, visible tablet, visible desktop, hidden phone, etc., you're now using classes called visible-sm for small, visible-md for medium, and visible-lg for large. Bootstrap 3 also adds classes for print design, and that's really cool, because it will let you decide whether certain elements in your layout will show up only when printed. So, although this is not a huge change, it's super important and deserves separate mention, because it's something that you'll have to replace or adapt to in your older layouts.
