 Some smaller changes made to the core Python language are:
 
-* The string :method:`format` method now supports automatic numbering
-  of the replacement fields.  This makes using :meth:`format`
-  more closely resemble using ``%s`` formatting::
+* :meth:`str.format` method now supports automatic numbering of the replacement

     >>> '{}:{}:{}'.format(2009, 04, 'Sunday')
     '2009:4:Sunday'
     >>> '{}:{}:{day}'.format(2009, 4, day='Sunday')
     '2009:4:Sunday'
 
-  The auto-numbering takes the fields from left to right, so the first
-  ``{...}`` specifier will use the first argument to :meth:`format`,
-  the next specifier will use the next argument, and so on.  You can't
-  mix auto-numbering and explicit numbering -- either number all of
-  your specifier fields or none of them -- but you can mix
-  auto-numbering and named fields, as in the second example above.

 * The :func:`int` and :func:`long` types gained a ``bit_length``
   method that returns the number of bits necessary to represent
