 - ``__wrap_iter``'s (iterator type for ``array``, ``span``, ``string``, ``string_view`` and ``vector``) ``base()``
   method has been removed as it was non-standard.
 
+- Removed the non-standard member type ``iterator_type`` from ``__wrap_iter``.
+  This member exposed the underlying iterator type and its removal prevents
+  users from relying on the implementation detail.
