+## 3.1.0
+May 3rd, 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.
+
+### Bug Fixes:
+- Feature variable APIs return default variable value when featureEnabled property is false. ([#162](https://github.com/optimizely/ruby-sdk/pull/162))
+
+### 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.
