Invoking the Interpreter
========================
-The Python interpreter is usually installed as :file:`/usr/local/bin/python3.11`
+The Python interpreter is usually installed as :file:`/usr/local/bin/python3.12`
on those machines where it is available; putting :file:`/usr/local/bin` in your
Unix shell's search path makes it possible to start it by typing the command:
.. code-block:: text
- python3.11
+ python3.12
to the shell. [#]_ Since the choice of the directory where the interpreter lives
is an installation option, other places are possible; check with your local
popular alternative location.)
On Windows machines where you have installed Python from the :ref:`Microsoft Store
-<windows-store>`, the :file:`python3.11` command will be available. If you have
+<windows-store>`, the :file:`python3.12` command will be available. If you have
the :ref:`py.exe launcher <launcher>` installed, you can use the :file:`py`
command. See :ref:`setting-envvars` for other ways to launch Python.

+
+.. 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.
+ (Contributed by P.Y. Developer in :issue:`12345`.)
+
+ This saves the maintainer the effort of going through the Mercurial log
+ when researching a change.
+
+This article explains the new features in Python 3.12, compared to 3.10.
+
+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 3.12 moves towards release,
+ so it's worth checking back even after reading earlier versions.

version (if any) is your "primary" version. Install that version using ``make
install``. Install all other versions using ``make altinstall``.
