+
+## 4.0.0-preview2 - March 7, 2024
+
+### Enhancements
+
+* Introduced a telemetry initializer named `TargetingTelemetryInitializer`. It automatically adds targeting information to telemetry data your application sends to Application Insights. This can be used to correlate your telemetry data with feature evaluation events based on the targeting information during your telemetry analysis.

+## 4.0.0-preview2 - March 7, 2024
+
+### Enhancements
+
+* Added a `TargetingId` property to the feature evaluation events sent to Application Insights. The `TargetingId` is the identifier of a targeted user during feature evaluation. This new property allows you to correlate feature evaluation events with other telemetry data your application sends to Application Insights, as long as they share the same `TargetingId`.
