 ## Changelog
+### 8.5.1
+- Introduced `IsDelta` into BaseResponseModel, which can help to determine if incoming data is part of the delta.
+- 
 ### 8.5.0
 - Assistant Stream now returns the `BaseResponse` type, but they can be cast to the appropriate types(`RunStepResponse`,`RunResponse`,`MessageResponse`). The reason for this change is that we realized the stream API returns multiple different object types rather than returning a single object type.
 - The Base Response now has a `StreamEvent` field, which can be used to determine the type of event while streaming.
