We=E2=80=99re getting closer and closer=E2=80=A6 Alpha 5 is here.

*This is an early developer preview of Python 3.13*
Major new features of the 3.13 series, compared to 3.12

Python 3.13 is still in development. This release, 3.13.0a5, is the fifth
of six planned alpha releases.

Alpha releases are intended to make it easier to test the current state of
new features and bug fixes and to test the release process.

During the alpha phase, features may be added up until the start of the
beta phase (2024-05-07) and, if necessary, may be modified or deleted up
until the release candidate phase (2024-07-30). Please keep in mind that
this is a preview release and its use is *not* recommended for production
environments.

Many new features for Python 3.13 are still being planned and written. Work
continues apace on both the work to remove the Global Interpeter Lock
<https://peps.python.org/pep-0703/>, and to improve Python performance. The
most notable changes so far:

   - In the interactive interpreter, exception tracebacks are now colorized
   by default
   <https://docs.python.org/dev/whatsnew/3.13.html#improved-error-messages>=
..
   - A preliminary, *experimental* JIT was added
   <https://docs.python.org/dev/whatsnew/3.13.html#experimental-jit-compile=
r>,
   providing the ground work for significant performance improvements.
   - Docstrings now have their leading indentation stripped
   <https://docs.python.org/dev/whatsnew/3.13.html#other-language-changes>,
   reducing memory use and the size of .pyc files. (Most tools handling
   docstrings already strip leading indentation.)
   - The dbm module <https://docs.python.org/dev/library/dbm.html> has a
   new dbm.sqlite3 backend
   <https://docs.python.org/dev/whatsnew/3.13.html#id1> that is used by
   default when creating new files.
   - PEP 594 (Removing dead batteries from the standard library)
   <https://peps.python.org/pep-0594/> scheduled removals of many
   deprecated modules: aifc, audioop, chunk, cgi, cgitb, crypt, imghdr,
   mailcap, msilib, nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau,
   telnetlib, uu, xdrlib, lib2to3.
   - Many other removals
   <https://docs.python.org/dev/whatsnew/3.13.html#removed> of deprecated
   classes, functions and methods in various standard library modules.
   - New deprecations
   <https://docs.python.org/dev/whatsnew/3.13.html#deprecated>, most of
   which are scheduled for removal from Python 3.15 or 3.16.
   - C API removals <https://docs.python.org/dev/whatsnew/3.13.html#id10>
   and deprecations <https://docs.python.org/dev/whatsnew/3.13.html#id9>.
   (Some removals present in alpha 1 have been reverted in alpha 2, as the
   removals were deemed too disruptive at this time.)

(Hey, *fellow core developer,* if a feature you find important is missing
from this list, let Thomas know <thomas@python.org>.)

The next pre-release of Python 3.13 will be 3.13.0a6, currently scheduled
for 2024-04-09.
