 Things to know when using the tooltip plugin:
 
-- Tooltips rely on the 3rd party library [Tether](http://tether.io/) for positioning. You must include [tether.min.js](https://github.com/HubSpot/tether/blob/master/dist/js/tether.min.js) before bootstrap.js in order for tooltips to work!
+- Tooltips rely on the 3rd party library [Popper.js](https://popper.js.org) for positioning. You must include [popper.min.js](https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.9.9/umd/popper.min.js) before bootstrap.js in order for tooltips to work!
 - Tooltips are opt-in for performance reasons, so **you must initialize them yourself**.
 - Tooltips with zero-length titles are never displayed.
 - Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
 - Triggering tooltips on hidden elements will not work.
 - Tooltips for `.disabled` or `disabled` elements must be triggered on a wrapper element.
 - When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use `white-space: nowrap;` on your `<a>`s to avoid this behavior.
+- Tooltips must be hidden before their corresponding elements have been removed from the DOM.
 
 Got all that? Great, let's see how they work with some examples.
