What's New In Python 3.10
|
|
|
|
|
****************************

: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 bug/patch number as a comment:
|
|
|
|
|
|
|
|
|
|
XXX Describe the transmogrify() function added to the socket
|
|
|
|
|
module.

This saves the maintainer the effort of going through the Mercurial log
|
|
|
|
|
when researching a change.

Prerelease users should be aware that this document is currently in draft
|
|
|
|
|
form. It will be updated substantially as Python 3.10 moves towards release,
|
|
|
|
|
so it's worth checking back even after reading earlier versions.
