## 3.4.0

July 8th, 2020

### New Features:

- Introduced 2 APIs to interact with feature variables:
- `getFeatureVariableJSON` allows you to get value for JSON variables related to a feature.
- `getAllFeatureVariables` gets values for all variables under a feature.
- Added support for fetching authenticated datafiles. `HTTPProjectConfigManager` now accepts `datafileAccessToken` to be able to fetch datafiles belonging to secure environments.

### Bug Fixes:

- Adjusted log level for audience evaluation logs. ([#198](https://github.com/optimizely/php-sdk/pull/198))
