 title: Deprecate ParaBackingState API
 doc:
-- audience: Node Operator
+- audience: [ Runtime Dev, Node Dev ]
   description: |-
-    Currently the `para_backing_state` API is used only by the prospective parachains subsystems and returns 2 things: the constraints for parachain blocks and the candidates pending availability.
+    Deprecates the `para_backing_state` API. Introduces and new `backing_constraints` API that can be used 
+    together with existing `candidates_pending_availability` to retrieve the same information provided by 
+    `para_backing_state`.
