## \[1.1.0] - January 30th, 2020

### New Features

- Added a new API to get project configuration static data.
- Call `getOptimizelyConfig()` to get a snapshot of project configuration static data.
- It returns an `OptimizelyConfig` instance which includes a datafile revision number, all experiments, and feature flags mapped by their key values.
- Added caching for `getOptimizelyConfig` - `OptimizelyConfig` object will be cached and reused for the lifetime of the datafile.
- For details, refer to our documentation page: [OptimizelyConfig for the React SDK](docId\:jMtfFpSf8yrB_jWRR6fjS).
