+		Version 9.4.4
+		- Improving the design for ITagService, let's allow setting key/values in one method call.
 		Version 9.4.2
 		- Contains an important improvement to QueryCommand, allowing a much faster lookup for the use-cases when the track and the query are very long and almost identical.
 		- The improvement is rooted in the idea of returning Candidates from the IModelService instead of list of SubFingerprints. This provided knowledge on which hashed fingerprint matched with the query.
