 	  Generalized some lemmas in a backward compatible way.
 	  Some strictly more general lemmas now have suffix `_dep`.
 
+	* Generalised {ffun A -> R} to handle dependent functions, and to be
+	  structurally positive so it can be used in recursive inductive type
+	  definitions. Minor backward incompatibilities: fgraph f is no longer
+	  a field accessor, and no longer equal to val f as {ffun A -> R} is no
