Alpha 2? But Alpha 1 only just came out!

https://www.python.org/downloads/release/python-3140a2/

This is an early developer preview of Python 3.14

Major new features of the 3.14 series, compared to 3.13:

Python 3.14 is still in development. This release, 3.14.0a2 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 (2025-05-06) and, if necessary, may be modified or deleted up
until the release candidate phase (2025-07-22). Please keep in mind that
this is a preview release and its use is not recommended for production environments.

Many new features for Python 3.14 are still being planned and written.
Among the new major new features and changes so far:

* PEP 649: deferred evaluation of annotations
* PEP 741: Python configuration C API
* PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers.
* Improved error messages
* (Hey, fellow core developer, if a feature you find important is missing
from this list, let Hugo know.)

The next pre-release of Python 3.14 will be 3.14.0a3, currently scheduled
for 2024-12-17.

And now for something completely different

Ludolph van Ceulen (1540-1610) was a fencing and mathematics teacher in
Leiden, Netherlands, and spent around 25 years calculating =CF=80 (or pi), = using
essentially the same methods Archimedes employed some seventeen hundred
years earlier.

Archimedes estimated =CF=80 by calculating the circumferences of polygons t= hat
fit just inside and outside of a circle, reasoning the circumference of the circle lies between these two values. Archimedes went up to polygons with
96 sides, for a value between 3.1408 and 3.1428, which is accurate to two decimal places.

Van Ceulen used a polygon with half a billion sides. He published a
20-decimal value in his 1596 book Vanden Circkel (=E2=80=9COn the Circle=E2= =80=9D), and
later expanded it to 35 decimals:

3.14159265358979323846264338327950288

Van Ceulen=E2=80=99s 20 digits is more than enough precision for any concei= vable
practical purpose. For example, even if a printed circle was perfect down
to the atomic scale, the thermal vibrations of the molecules of ink would
make most of those digits physically meaningless. NASA Jet Propulsion Laboratory=E2=80=99s highest accuracy calculations, for interplanetary navi= gation,
uses 15 decimals: 3.141592653589793.

At Van Ceulen=E2=80=99s request, his upper and lower bounds for =CF=80 were=
engraved on
his tombstone in Leiden. The tombstone was eventually lost but restored in 2000. In the Netherlands and Germany, =CF=80 is sometimes referred to as th=
e
=E2=80=9CLudolphine number=E2=80=9D, after Van Ceulen.
