 ## Unreleased
 
+* Removed the Activity Status Description that was being set during unhandled
+  exceptions. Activity Status will continue to be reported as `Error`.
+  This is a **breaking change**. `EnrichWithException` can be leveraged
+  to restore this behavior.
+  ([#5025](https://github.com/open-telemetry/opentelemetry-dotnet/pull/5025))
