In the SC meeting today we discussed requiring two-factor authentication
(aka 2FA/MFA) and came away strongly considering it (but no definitive
plans yet). But we did agree that we should send a quick email encouraging
everyone to turn on 2FA for their GitHub Accounts regardless of what we
decide to do.
GitHub's instructions can be found at
https://docs.github.com/en/authentication/securing-your-account-with-two-fa…
. You can use various apps on your desktop or phone as well as a physical
device to manage 2FA. And to be clear, you only need access to your 2FA
solution when you log in; it's not a day-to-day action at all (I personally
have not used my 2FA since the last time I logged into a new device for the
first time or when my GitHub account was attacked and the attackers
exhausted my password attempts for the day).
For those of you who would prefer to use a hardware device and would like
help getting one, we can make a request to the PSF to sponsor devices for
those who want them.
Greetings!
Is there a list somewhere of the core developers and triagers?
I'm looking to prune the core-mentorship subscriber list as I'm confident 90%+ are folks that wanted help learning
Python, not folks wanting help to develop Python itself. Towards that end I want to unsubscribe anyone who has not been
active in the last six months, excepting core-devs and triagers.
Any and all help appreciated!

We needed to tame some angry buildbots, but after a small fight, we won
with just some scratches! Here you have a shiny new alpha release: Python
3.11.0a5.
https://www.python.org/downloads/release/python-3110a5/
**This is an early developer preview of Python 3.11**
# Major new features of the 3.11 series, compared to 3.10
Python 3.11 is still in development. This release, 3.11.0a5 is the fifth
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/) -- Include
Fine-Grained Error Locations in Tracebacks
* [PEP 654](https://www.python.org/dev/peps/pep-0654/) -- Exception Groups
and except*
* [PEP 673](https://www.python.org/dev/peps/pep-0673/) -- Self Type
* [PEP 646](https://www.python.org/dev/peps/pep-0646/)-- Variadic Generics
* The [Faster Cpython Project](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](
speed.python.org), compared to 3.10.0.
* Hey, **fellow core developer,** if a feature you find important is
missing from this list, let me know.
The next pre-release of Python 3.11 will be 3.11.0a6, currently scheduled
for Monday, 2022-02-28.
# More resources
* [Online Documentation](https://docs.python.org/3.11/)
* [PEP 664](https://www.python.org/dev/peps/pep-0664/), 3.11 Release
Schedule
* Report bugs at [https://bugs.python.org](https://bugs.python.org).
* [Help fund Python and its community](/psf/donations/).
# And now for something completely different
In physics, the Poynting vector (Umov-Poynting vector) represents the
directional energy flux (the energy transfer per unit area per unit time)
or power flow of an electromagnetic field. It is named after its discoverer
John Henry Poynting who first derived it in 1884. Oliver Heaviside also
discovered it independently in the more general form that recognises the
freedom of adding the curl of an arbitrary vector field to the definition.
The Poynting vector is used throughout electromagnetics in conjunction with
Poynting’s theorem, the continuity equation expressing conservation of
electromagnetic energy, to calculate the power flow in electromagnetic
fields.
# We hope you enjoy those new releases!
Thanks to all of the many volunteers who help make Python Development and
these releases possible! Please consider supporting our efforts by
volunteering yourself or through organization contributions to the Python
Software Foundation.
