 Removed
 -------
 
 * Creating :c:data:`immutable types <Py_TPFLAGS_IMMUTABLETYPE>` with mutable
   bases was deprecated since 3.12 and now raises a :exc:`TypeError`.
 
+* Remove ``PyDictObject.ma_version_tag`` member which was deprecated since
+  Python 3.12. Use the :c:func:`PyDict_AddWatcher` API instead.
+  (Contributed by Sam Gross in :gh:`124296`.)

 * Remove the private ``_Py_InitializeMain()`` function. It was a
   :term:`provisional API` added to Python 3.8 by :pep:`587`.
