Awesome changelog with great migration instructions. Bravo to the React team!

Going to set aside some hours on Saturday to upgrade our React version.

I recently started to go in with functional components where I don't need life-cycle events such as componentDidMount. Does anyone know if React is planning to make optimizations for code structured in this way?

Eventually, yes. The original release notes announcing functional components mentioned that they would "eventually" add some optimizations, but many people assumed that meant they already _are_ optimized. Right now, there aren't any special optimizations for functional components.
