Java-SDK - 3.1.0 – Support Help Center

## 3.1.0
May 6th, 2019

### New Features:
- Introduced Decision notification listener to be able to record:
- Variation assignments for users activated in an experiment.
- Feature access for users.
- Feature variable value for users.
- Added APIs to be able to conveniently add Decision notification handler (`addDecisionNotificationHandler`) and Track notification handler (`addTrackNotificationHandler`).

### Bug Fixes:
- Feature variable APIs return default variable value when featureEnabled property is false. ([#274](https://github.com/optimizely/java-sdk/pull/274))

### Deprecated
- Activate notification listener is deprecated as of this release. Recommendation is to use the new Decision notification listener. Activate notification listener will be removed in the next major release.
- `addActivateNotificationListener`, `addTrackNotificationListener` and `addNotificationListener` APIs on `NotificationCenter`.
