 - Added to `GHC.Prim`:
 
-        isPinnedByteArray# :: MutableByteArray# s -> Int#

+- New primitives for compact regions in `GHC.Prim`:

+- Generalised `noDuplicate#` from
+
+        noDuplicate# :: State# (RealWorld) -> State# (RealWorld)
+
+    to
+
+        noDuplicate# :: State# s -> State# s
