Tcl/Tk updates

With the recent release of macOS 12 Monterey, we noticed that tkinter =
file dialogs are failing to show up on this new operating system, =
including in our built-in IDLE. Thanks to rapid help from the Tk team, =
and Marc Culler in particular, we were able to fix the issue by bundling = Python 3.9.8 and Python 3.11.0a2 with a fixed Tcl/Tk version. In 3.9.8 = it=E2=80=99s a patched 8.6.11 release while 3.11.0a2 is rocking the = bleeding-edge 8.6.12rc1.

Since the issue also affected our latest stable version, 3.10.0, an =
updated macOS installer for this version was issued. You can recognize =
it by the post2 version appendix: python-3.10.0post2-macos11.pkg = <https://www.python.org/ftp/python/3.10.0/python-3.10.0post2-macos11.pkg>.=
We didn=E2=80=99t have to bump the version number of Python itself =
since there are no Python source differences between this package and =
the original 3.10.0. The only difference is the bundled patched Tcl/Tk = library.

Initially the original 3.10.0 installer was removed from the website =
after all URLs got updated to point to the patched version but it turned =
out this breaks some workflows = <https://discuss.python.org/t/disappearing-macos-packages-on-python-org/11=

so the patched installer is now also available under the original =

filename.

Get it here: https://www.python.org/downloads/release/python-398/ = <https://www.python.org/downloads/release/python-398/>

Python 3.9.8 is the seventh maintenance release of the legacy 3.9 =
series. Python 3.10 is now the latest feature release series of Python =
3. Get the latest release of 3.10.x here =
<https://python.org/downloads/>.
There=E2=80=99s been 202 commits since 3.9.7 which shows that there=E2=80=99=
s still considerable interest in improving Python 3.9. To compare, at =
the same stage of the release cycle Python 3.8 received over 25% fewer = commits. See the changelog = <https://docs.python.org/release/3.9.8/whatsnew/changelog.html> for =
details on what changed.

On macOS, the default installer is now the new universal2 variant. = It=E2=80=99s compatible with Mac OS X 10.9 and newer, including macOS 11 =
Big Sur and macOS 12 Monterey. You may need to upgrade third-party = components, like pip, to the newest versions. You may experience =
differences in behavior in IDLE and other Tk-based applications due to =
using the newest version of Tk. As always, if you encounter problems =
when using this installer variant, please check https://bugs.python.org = <https://bugs.python.org/> for existing reports and for opening new =
issues.

The next Python 3.9 maintenance release will be 3.9.9, currently =
scheduled for 2022-01-03.

Python 3.11 is still in development. This release, 3.11.0a2 is the =
second of seven 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 (2022-05-06) and, if necessary, may be modified or deleted up = until the release candidate phase (2022-08-01). Please keep in mind that =
this is a preview release and its use is not recommended for production = environments.

Many new features for Python 3.11 are still being planned and written. =
Among the new major new features and changes so far:

PEP 657 <https://www.python.org/dev/peps/pep-0657/> =E2=80=93 Include = Fine-Grained Error Locations in Tracebacks
The Faster CPython Project 1 <https://github.com/faster-cpython> is =
already yielding some exciting results: this version of CPython 3.11 is =
~12% faster on the geometric mean of the PyPerformance benchmarks <>, = compared to 3.10.0.
(Hey, fellow core developer, if a feature you find important is missing =
from this list, let Pablo know <mailto:pablogsal@python.org>.)
The next pre-release of Python 3.11 will be 3.11.0a3, currently =
scheduled for Monday, 2021-12-06.
