## 3.4.0

January 31st, 2020

This release includes a new API to access project configuration data.

### 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.
