[API CHANGES]
+ * 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 ->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
* Added a Moose::Meta::Method->is_stub method. (Dave Rolsky)
+ [BUG FIXES]
+
+ * A subtype of a union type did not return the right results when you called
+ ->is_subtype_of or ->is_a_type_of on it. This has been fixed. RT
+ #70322. (Dave Rolsky)
+
* An attribute accessor or delegation method can overwrite a stub method and
this will no longer throw an error. Reported by Mark-Jason Dominus. Fixes
RT 69988. (Dave Rolsky)
+ * The error generated by unfulfilled method requirements during role
+ composition now mentions how to work around imported methods not being
+ recognized. Reported by Michael Schwern. Fixes RT 60583. (doy)
+
+ * class_type and role_type will now throw errors if you attempt to use them
+ to override existing types, just like type and subtype have always done.
+ (doy)
+
+ * Implicitly creating class or role types by using them as the 'isa' or
+ 'does' parameter to attribute construction will now register the type. This
+ means that it cannot later be redefined as something else. (doy)
+
