Re: [RELEASE] Python 3.12.3 and 3.13.0a6 released

I have to comment on this one: "Docstrings now have their leading
indentation stripped"

Incredibly useful!

What’s that? The last alpha release? Just one more month until feature
freeze! Get your features done, get your bugs fixed, let’s get 3.13.0 ready
for people to actually use! Until then, let’s test with alpha 6. The
highlights of 3.13 you ask? Well:
>
   - 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-compiler>,
   providing the ground work for significant performance improvements.
   - The (cyclic) garbage collector is now incremental
   <
https://docs.python.org/dev/whatsnew/3.13.html#incremental-garbage-collection

,

   which should mean shorter pauses for collection in programs with a lot
of
   objects.
   - 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 were reverted in alpha 2, as the
removals
   were deemed too disruptive at this time.)
