React and React-Dom versions should match?

Question

Do React and React-Dom have to be the same version?

Example in our app:

React v 15.0.2, React-Dom v 15.3.1

Everything has been working fine in our app until recently, we are getting a strange error.

Type Error: Cannot read property 'getNativeNode' of null (ReactReconciler)

Answer 1

For versions lesser equal than 15.4 they should match.

After release on Nov 16 2016 they have finally separated React and React DOM.
