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 as a comment:
|
|
|
|
% Patch 12345
|
|
XXX Describe the transmogrify() function added to the socket
|
|
module.

|
|
|
|
This saves the maintainer the effort of going through the SVN log
|
|
when researching a change.
|
|
|
|
This article explains the new features in Python 3.2, compared to 3.1.

PEP XXX: Stub
|
|
=============
|
|
|
|
|
|
Other Language Changes
|
|
======================
|
|
|
|
Some smaller changes made to the core Python language are:
|
|
|
|
* Stub
|
|
|
|
|
|
New, Improved, and Deprecated Modules
|
|
=====================================
|
|
|
|
* 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.
|
|
|
|
(Contributed by Georg Brandl; :issue:`5675`.)
|
|
|
|
* 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.
