What's New In Python 3.13
|

****************************
|
||||
|
||||
:Release: |release|
|
||||
:Date: |today|
|
||||
|
||||
.. 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 issue number as a comment:
|
||||
|
||||
XXX Describe the transmogrify() function added to the socket
|
||||
module.
|
||||
(Contributed by P.Y. Developer in :gh:`12345`.)
|
||||
|
||||
This saves the maintainer the effort of going through the VCS log
|
||||
when researching a change.

||||

||||
This article explains the new features in Python 3.13, compared to 3.12.

For full details, see the :ref:`changelog <changelog>`.
|
||||
|
||||
.. note::
|
||||
|
||||
Prerelease users should be aware that this document is currently in draft
|
||||
form. It will be updated substantially as Python 3.13 moves towards release,
|
||||
so it's worth checking back even after reading earlier versions.
