Love those diagrams! There are a number of major modules that I certainly have used but never directly by name.

It is unfortunate that they are drawn with slightly different orientation of the major sections and different spacing. That makes them feel more different than just the class/module names imply. There are only a few additions from 3 -> 4, engines, streaming.
