## \[2.8.1]

March 7, 2022

### Enhancements

\- fixed issue \[#49]\([https://github.com/optimizely/react-sdk/issues/49](https://github.com/optimizely/react-sdk/issues/49)): Return type of `createInstance` was `OptimizelyReactSDKClient` which is the implementation class.

\- fixed issue \[#121]\([https://github.com/optimizely/react-sdk/issues/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](https://github.com/optimizely/react-sdk/pull/150))).
