   - Item access (e.g. ``eps[name]``) retrieves a single
     entry point by name.
 
-  ``entry_points()`` now returns an ``EntryPoints``

-  a ``__getitem__`` accessor by group and a ``get()``

+  ``entry_points()`` now provides a future-compatible
+  ``SelectableGroups`` object that supplies the above interface

+  In the future, ``entry_points()`` will return an

+  If passing selection parameters to ``entry_points``, the

   Construction of entry points using
   ``dict([EntryPoint, ...])`` is now deprecated and raises
