 ## Unreleased
 
+* **[Breaking]** `Enrich` callback is now split into 3 different callbacks based
+on the object that is passed in to enrich activity. The new callbacks are
+`EnrichWithHttpRequest`, `EnrichWithHttpResponse` and `EnrichWithException`.
+([#3749](https://github.com/open-telemetry/opentelemetry-dotnet/pull/3749))

 * Added back `netstandard2.0` and `netstandard2.1` targets.

 ### Enrich
 
-This option allows one to enrich the activity with additional information
-from the raw `HttpRequest`, `HttpResponse` objects. The `Enrich` action is
-called only when `activity.IsAllDataRequested` is `true`. It contains the
-activity itself (which can be enriched), the name of the event, and the
-actual raw object.
-For event name "OnStartActivity", the actual object will be `HttpRequest`.

+only when `activity.IsAllDataRequested` is `true`. It contains the activity
