React-dom version 16.5.1 does not render anything in Codepen

Guys what’s wrong with the latest react dom version 16.5.1 ? did they change the render method? i’m getting a “ReactDOM is not defined” error in Codepen: however if i switch back to 16.4.2 it works perfectly fine.

I guess the react-dom version 16.5.1

Here is the change log.

Can’t see anything to do with your problem.
I would stick with an older version if I were you
