Maybe a dumb question or wrong forum. But how do you start using latest React in a project?
The current version of React is 16.2 (see release notes: https://reactjs.org/blog/2017/11/28/react-v16.2.0-fragment-s... ). 16.3 is getting closer to release and will include several new aspects, such as revisions to the lifecycle methods and a simpler `createRef` API. The async stuff that was demoed today is likely to be in a 16.4 release later this year.
