The new floating point string representations can break existing doctests. For example::
2895
def e(): '''Compute the base of natural logarithms. >>> e() 2.7182818284590451 ''' return sum(1/math.factorial(x) for x in reversed(range(30))) doctest.testmod() ********************************************************************** Failed example: e() Expected: 2.7182818284590451 Got: 2.718281828459045 **********************************************************************

The automatic name remapping in the pickle module for protocol 2 or lower can make Python 3.1 pickles unreadable in Python 3.0. One solution is to use protocol 3. Another solution is to set the *fix_imports* option to **False**. See the discussion above for more details.

The :class:`ftplib.FTP` class now supports the context manager protocol (Contributed by Tarek Ziadé and Giampaolo Rodolà; :issue:`4972`.)

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.
