React: Hooks are disabled in v16.7.0-alpha.1

Oops. Sorry.

enableStableConcurrentModeAPIs is false on this release as well, by the way!

Maybe unpublish 16.7.0-alpha.1? I believe most people are using the next version because of hooks.

I got here by installing react@next and thinking I was doing something wrong because React.useState was undefined.

Heh. Just spent good hour trying to figure out why useState is not defined on React. Will this be changed or should I look for some other version?

Previous alpha release had incorrect feature flags due to a build script snafu. (I even tested with NPM+CRA but apparently the @next tag hadn't propagated yet) 😳

Fortunately we have some ideas on how to prevent this sort of thing from happening in the future:

Sorry for the inconvenience.
