v2.1.0

 - `React\EventLoop\Factory` is now automatically replaced with another implementation that throws on each usage to prevent two loops existing concurrently by accident. Set `AMP_REACT_ADAPTER_DISABLE_FACTORY_OVERRIDE=1` as environment variable or as a constant to disable this protection.

v2.0.0

 - Make compatible with `react/event-loop` @ `^0.5 || ^1`

 - Made `ReactAdapter`'s constructor public so it can be used without

Amp's global loop.

Initial release.
