[RELEASE] Python 3.11.0a5 is available
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 -- Include Fine-Grained Error Locations in Tracebacks
- PEP 654 -- Exception Groups and except*
- PEP 673 -- Self Type
- PEP 646-- Variadic Generics
- The Faster Cpython Project 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 me know.
The next pre-release of Python 3.11 will be 3.11.0a6, currently scheduled for Monday, 2022-02-28.

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!

Only 12%? Did you measure this on the same machine as usual? My measurements show a geometric mean of ~19%, although the range is -2% to +71%. I would just say "about 20%". 19% (or 12%) suggests rather more precision than is justifiable.
Cheers, Mark.
Hi Mark,
Apologies, I forgot to update the numbers in the text :(
I will update them in all places where I can edit the text (download page and discourse).
Thanks for pointing that out!
Cheers from sunny London, Pablo
