 ### Deprecation Notice
 
-TBD
+- We are now actively engaged in the process of integrating the functionalities of the `File` and `Dataset` services. It is important to note that, going forward, our primary focus will be on enhancing and prioritizing the capabilities of the `Dataset` service in the domain of file/dataset delivery. As of the present, both services remain accessible and operational. Further elaboration on this matter will be communicated in due course.
