 ### Enhancements
 - fixed issue [#49](https://github.com/optimizely/react-sdk/issues/49): Return type of `createInstance` was `OptimizelyReactSDKClient` which is the implementation class. Changed it to the `ReactSDKClient` interface instead ([#148](https://github.com/optimizely/react-sdk/pull/148)).
 
 - fixed issue [#121](https://github.com/optimizely/react-sdk/issues/121):`ActivateListenerPayload` and `TrackListenerPayload` types were exported from `@optimizely/optimizely-sdk` but were missing from `@optimizely/react-sdk` exports. ([#150](https://github.com/optimizely/react-sdk/pull/150)).
