    At unpickling time, some methods like :meth:`__getattr__`,
    :meth:`__getattribute__`, or :meth:`__setattr__` may be called upon the
    instance.  In case those methods rely on some internal invariant being
-   true, the type should implement :meth:`__getnewargs__` or
-   :meth:`__getnewargs_ex__` to establish such an invariant; otherwise,
-   neither :meth:`__new__` nor :meth:`__init__` will be called.
+   true, the type should implement :meth:`__new__` to establish such an
+   invariant, as :meth:`__init__` is not called when unpickling an
+   instance.
