.. Patch 1507
|

|

* More floating-point features were also added. The :func:`float` function
|

will now turn the strings ``+nan`` and ``-nan`` into the corresponding
|

IEEE 754 Not a Number values, and ``+inf`` and ``-inf`` into

positive or negative infinity. This works on any platform with

IEEE 754 semantics. (Contributed by Christian Heimes.)

.. Patch 1635.
|

|

* Changes to the :class:`Exception` interface
|

as dictated by :pep:`352` continue to be made. For 2.6,
|

the :attr:`message` attribute is being deprecated in favor of the

``"mant_dig"`` (number of digits in the mantissa), ``"epsilon"``

(smallest difference between 1.0 and the next largest value

representable), and several others.

.. Issue 1534
|

|

* Python's C API now includes two functions for case-insensitive string
|

comparisions, ``PyOS_stricmp(char*, char*)``
|

and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

.. Issue 1635
|

* Some macros were renamed. :cmacro:`Py_Size()` became :cmacro:`Py_SIZE()`,
|
||||
:cmacro:`Py_Type()` became :cmacro:`Py_TYPE()`, and
|
||||
:cmacro:`Py_Refcnt()` became :cmacro:`Py_REFCNT()`. Macros for backward

* The :mod:`msvcrt` module now supports

both the normal and wide char variants of the console I/O

API. The :func:`getwch` function reads a keypress and returns a Unicode

This section lists previously described changes, and a few

esoteric bugfixes, that may require changes to your

* The :method:`__init__` method of :class:`collections.deque`

now clears any existing contents of the deque

before adding elements from the iterable. This change makes the

behavior match that of ``list.__init__()``.

* The :mod:`socket` module exception :exc:`socket.error` now inherits
