 # Changelog
 
+## [Unreleased](https://github.com/Instabug/Instabug-Flutter/compare/v13.2.0...dev)
+
+### Added
+
+- Add support for variants in Feature Flags through the APIs `Instabug.addFeatureFlags`, `Instabug.removeFeatureFlags` and `Instabug.clearAllFeatureFlags` ([#471](https://github.com/Instabug/Instabug-Flutter/pull/471)).
+
+### Deprecated
+
+- Deprecate Experiments APIs `Instabug.addExperiments`, `Instabug.removeExperiments` and `Instabug.clearAllExperiments` in favor of the new Feature Flags APIs ([#471](https://github.com/Instabug/Instabug-Flutter/pull/471)).
+
 ## [13.2.0](https://github.com/Instabug/Instabug-Flutter/compare/v13.1.1...v13.2.0)
