* The optimize_as option for type constraints has been deprecated. Use the
inline_as option to provide inlining code instead. (Dave Rolsky)
+ [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
+ true. Fixes RT #67731. (Dave Rolsky)
+
[ENHANCEMENTS]
* The Moose::Exporter module now has a "meta_lookup" option when creating an
MooseX::Role::Parameterized which generate new metaclasses on the

+ * Added a Moose::Meta::Method->is_stub method. (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)
+
+ [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)
