* The :func:`string.maketrans` function is deprecated and is replaced by new
static methods, :meth:`bytes.maketrans` and :meth:`bytearray.maketrans`.
This change solves the confusion around which types were supported by the

:class:`bytearray` each have their own **maketrans** and **translate**
methods with intermediate translation tables of the appropriate type.

* ``round(x, n)`` now returns an integer if *x* is an integer. * ``round(x, n)`` now returns an integer if *x* is an integer.
