+## 2.2.0 - March 11, 2025
+
+### Enhancements
+
+* Added support for on-demand refresh of ConfigMap and Secret. While you can set up automatic data refresh, there are times when you might want to trigger an on-demand refresh to get the latest data from App Configuration and Key Vault. To do this, you can modify the `metadata.annotations` section. This enhancement makes the refresh process more flexible and better suited to your workflow. [#87](https://github.com/Azure/AppConfiguration-KubernetesProvider/pull/87)
+* Added support for variant feature flags.
+* Added support for injecting additional telemetry metadata to feature flags if telemetry is enabled, including `FeatureFlagId`, `FeatureFlagReference`, and `ETag`. [#94](https://github.com/Azure/AppConfiguration-KubernetesProvider/pull/94)
+*  Upgraded dependent packages. [#96](https://github.com/Azure/AppConfiguration-KubernetesProvider/pull/96)
+
+### Bug Fixes
+
+* Fixed a bug where the order of feature flags might not be retained between refreshes. [#75](https://github.com/Azure/AppConfiguration-KubernetesProvider/issues/75)
+* Fixed a regression bug in version 2.1.0 that may cause the Kubernetes provider to crash with an `invalid memory address or nil pointer dereference` error when `selectors.snapshotName` is specified. [#93](https://github.com/Azure/AppConfiguration-KubernetesProvider/pull/93)
