React v16.9 Released and a Roadmap Update — In 16.9, the unsafe lifecycle methods (e.g. componentWillMount) have been renamed (the old names will work with warnings for now), act() will now work with async functions, and there’s a new way to get performance measurements programmatically using <React.Profiler>.
