 ### Improvements
 
 - **General:** Synchronize HPA annotations from ScaledObject ([#2659](https://github.com/kedacore/keda/pull/2659))
-- **Azure Event Hub Scaler:** Improve logging when blob container not found ([#2363]https://github.com/kedacore/keda/issues/2363)
+- **Azure Application Insights Scaler:** Provide support for non-public clouds ([#2735](https://github.com/kedacore/keda/issues/2735))
+- **Azure Event Hub Scaler:** Improve logging when blob container not found ([#2363](https://github.com/kedacore/keda/issues/2363)
 - **Azure Event Hub Scaler:** Provide support for non-public clouds ([#1915](https://github.com/kedacore/keda/issues/1915))
 - **Azure Queue:** Don't call Azure queue GetProperties API unnecessarily ([#2613](https://github.com/kedacore/keda/pull/2613))
 - **Datadog Scaler:** Validate query to contain `{` to prevent panic on invalid query ([#2625](https://github.com/kedacore/keda/issues/2625))
