[API CHANGES]
+ * Methods to introspect a class's methods will now return methods defined in
+ UNIVERSAL (isa, can, etc.). This also means that you can wrap these
+ methods with method modifiers. RT #69839. Reported by Vyacheslav
+ Matyukhin. (Dave Rolsky)
+
* The ->parent and ->parents method for a union now return the nearest
common ancestor of that union's component types. See Moose::Manual::Delta
for more details. (Dave Rolsky)
+ * The ->parents method used to return an arrayref for union types, and a
+ list of one or more types for all other types. Now they all return
+ lists. (Dave Rolsky)
+
* The ->is_subtype_of and ->is_a_type_of methods have changed their
behavior. Previously, they returned true if any of their member types
returned true for a given type. Now, all of the member types must return
'does' parameter to attribute construction will now register the type. This
means that it cannot later be redefined as something else. (doy)
+ * $class_type->is_subtype_of no longer returns true if passed the name of the
+ class that the class type represents when the class type wasn't registered.
+ (doy)
+
+ * Removing anonymous metaclasses prematurely no longer prevents reaping of
+ the associated stash. (doy)
