## \[3.4.0] - January 27th, 2020

### New Features:

- Added a new API to get project configuration static data.
- Call `get_optimizely_config()` 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 `get_optimizely_config()` - `OptimizelyConfig` object will be cached and reused for the lifetime of the datafile.
- For details, refer to our documentation page: [OptimizelyConfig for the Python SDK](docId\:hyemSKdINH-zFg2-epg60).
