Python 2.6 adds :class:`bytes` as a synonym for the :class:`str` type,
and it also supports the ``b''`` notation.
The 2.6 :class:`str` differs from 3.0's :class:`bytes` type in various
ways; most notably, the constructor is completely different. In 3.0,
``bytes([65, 66, 67])`` is 3 elements long, containing the bytes
representing ``ABC``; in 2.6, ``bytes([65, 66, 67])`` returns the
12-byte string representing the :func:`str` of the list.
The primary use of :class:`bytes` in 2.6 will be to write tests of
object type such as ``isinstance(x, bytes)``. This will help the 2to3
converter, which can't tell whether 2.x code intends strings to
contain either characters or 8-bit bytes; you can now
use either :class:`bytes` or :class:`str` to represent your intention
exactly, and the resulting code will also be correct in Python 3.0.
There's also a ``__future__`` import that causes all string literals
to become Unicode strings. This means that ``\u`` escape sequences

Rules for maintenance:
* Anyone can add text to this document. Do not spend very much time
on the wording of your changes, because your text will probably
get rewritten to some degree.
* The maintainer will go through Misc/NEWS periodically and add
changes; it's therefore more important to add your changes to
Misc/NEWS than to this file.
* This is not a complete list of every single change; completeness
is the purpose of Misc/NEWS. Some changes I consider too small
or esoteric to include. If such a change is added to the text,
I'll just remove it. (This is another reason you shouldn't spend
too much time on writing your addition.)
* If you want to draw your new text to the attention of the
maintainer, add 'XXX' to the beginning of the paragraph or
section.
* It's OK to just add a fragmentary note about a change. For
example: "XXX Describe the transmogrify() function added to the
socket module." The maintainer will research the change and
write the necessary text.
* You can comment out your additions if you like, but it's not
necessary (especially when a final release is some months away).
* Credit the author of a patch or bugfix. Just the name is
sufficient; the e-mail address isn't necessary.
* It's helpful to add the bug/patch number in a parenthetical comment.

module.
