@@ -28,6 +28,12 @@ Language - Several evolutions of the module system (handling of module aliases, functorial module types, an Include feature, etc). (TODO: Say more!) - Prop now a subtype of Set (predicative and impredicative forms). +- Recursive inductive types in Prop with a single constructor of which + all arguments are in Prop is now considered to be a singleton + type. It consequently supports all eliminations to Prop, Set and Type. + As a consequence, Acc_rect has now a more direct proof [possible source + of easily fixed incompatibility in case of manual definition of a recursor + in a recursive singleton inductive type].
