React 16.4 features in Rum, testing and feedback needed


#1

I’ve started working on API wrappers of React 16.4 features for Rum. Please test it on your projects if you are using Rum, looking for feedback on this.

So far there’s only one change that breaks existing users if they want to transition to React 16.4: deprecations in lifecycles. Read “Lifecycles” section in the PR.
