2.0.64 has removed prop-types which are **required** for react v16 compatibility

I diffed the 2.0.64 changes and was extremely disappointed that the references to prop-types, which are needed for react v16 compatibility were removed.

Why are you moving the project farther away from v16?

From: https://reactjs.org/blog/2017/09/26/react-v16.0.html

The deprecations introduced in 15.x have been removed from the core package. React.createClass is now available as create-react-class, React.PropTypes as prop-types, React.DOM as react-dom-factories, react-addons-test-utils as react-dom/test-utils, and shallow renderer as react-test-renderer/shallow. See 15.5.0 and 15.6.0 blog posts for instructions on migrating code and automated codemods.

This does not seem correct. PR (#954) migrated React.PropTypes to separate prop-types package and was merged yesterday.

You are correct!
I misread the diff -- sorry for the confusion.
