The previously deprecated :func:`string.maketrans` function has been removed in favor of the static methods, :meth:`bytes.maketrans` and :meth:`bytearray.maketrans`. This change solves the confusion around which types were supported by the :mod:`string` module. Now, :class:`str`, :class:`bytes`, and :class:`bytearray` each have their own **maketrans** and **translate** methods with intermediate translation tables of the appropriate type.

The previously deprecated :func:`contextlib.nested` function has been removed in favor of a plain :keyword:`with` statement which can accept multiple context managers. The latter technique is faster (because it is built-in), and it does a better job finalizing multiple context managers when one of them raises an exception.

The :func:`shutil.copytree` function has two new options:
2905
*ignore_dangling_symlinks*: when ``symlinks=False`` (meaning that the function copies the file pointed to by the symlink, not the symlink itself) this option will silence the error thrown if the file doesn't exist.
2906
*copy_function*: a callable that will be used to copy files. :func:`shutil.copy2` is used by default.
