Here’s the second 3.14 beta.
https://www.python.org/downloads/release/python-3140b2/
This is a beta preview of Python 3.14
Python 3.14 is still in development. This release, 3.14.0b2, is the
second of four planned beta releases.
Beta release previews are intended to give the wider community the
opportunity to test new features and bug fixes and to prepare their
projects to support the new feature release.
We strongly encourage maintainers of
third-party Python projects to test with 3.14
during the beta phase and report issues found to the Python bug
tracker as soon as possible. While the release is planned to be
feature-complete entering the beta phase, it is possible that features
may be modified or, in rare cases, deleted up until the start of the
release candidate phase (Tuesday 2025-07-22). Our goal is to have
no ABI changes after beta 4 and as few code
changes as possible after the first release candidate. To achieve that,
it will be extremely important to get as much
exposure for 3.14 as possible during the beta phase.
This includes creating pre-release wheels for 3.14, as it helps other
projects to do their own testing. However, we recommend that your
regular production releases wait until 3.14.0rc1, to avoid the risk of
ABI breaks.
Please keep in mind that this is a preview release and its use is
not recommended for production
environments.
Major

New features
(Hey, fellow core developer, if a feature you
find important is missing from this list, let Hugo know.)
For more details on the changes to Python 3.14, see What’s new in
Python 3.14. The next pre-release of Python 3.14 will be 3.14.0b3,
scheduled for 2025-06-17.
Build changes
- PEP
761: Python 3.14 and onwards no longer provides PGP signatures for
release artifacts. Instead, Sigstore is recommended for verifiers.
- Official macOS and Windows release binaries include an experimental
JIT compiler.
Incompatible
changes, removals and new deprecations
Python install manager
The installer we offer for Windows is being replaced by our new
install manager, which can be installed from the Windows
Store or our
FTP page. See our
documentation for more information. The JSON file available for
download below contains the list of all the installable packages
available as part of this release, including file URLs and hashes, but
is not required to install the latest release. The traditional installer
will remain available throughout the 3.14 and 3.15 releases.

And now for
something completely different
In 1897, the State of Indiana almost passed a bill defining
π as 3.2.
Of course, it’s not that simple.
Edwin J. Goodwin, M.D., claimed to have come up with a solution to an
ancient geometrical problem called squaring the circle, first proposed
in Greek mathematics. It involves trying to draw a circle and a square
with the same area, using only a compass and a straight edge. It turns
out to be impossible because π is transcendental (and this had
been proved just 13 years earlier by Ferdinand von Lindemann), but
Goodwin fudged things so the value of π was 3.2 (his writings
have included at least nine different values of π: including 4,
3.236, 3.232, 3.2325… and even 9.2376…).
Goodwin had copyrighted his proof and offered it to the State of
Indiana to use in their educational textbooks without paying royalties,
provided they endorsed it. And so Indiana Bill No. 246 was introduced to
the House on 18th January 1897. It was not understood and initially
referred to the House Committee on Canals, also called the Committee on
Swamp Lands. They then referred it to the Committee on Education, who
duly recommended on 2nd February that “said bill do pass”. It passed its
second reading on the 5th and the education chair moved that they
suspend the constitutional rule that required bills to be read on three
separate days. This passed 72-0, and the bill itself passed 67-0.
The bill was referred to the Senate on 10th February, had its first
reading on the 11th, and was referred to the Committee on Temperance,
whose chair on the 12th recommended “that said bill do pass”.
A mathematics professor, Clarence
Abiathar Waldo, happened to be in the State Capitol on the day the
House passed the bill and walked in during the debate to hear an
ex-teacher argue:
The case is perfectly simple. If we pass this bill which establishes
a new and correct value for pi , the author offers to our state without
cost the use of his discovery and its free publication in our school
text books, while everyone else must pay him a royalty.
Waldo ensured the senators were “properly coached”; and on the 12th,
during the second reading, after an unsuccessful attempt to amend the
bill it was postponed indefinitely. But not before the senators had some
fun.
The Indiana News reported on the 13th:
…the bill was brought up and made fun of. The Senators made bad puns
about it, ridiculed it and laughed over it. The fun lasted half an hour.
Senator Hubbell said that it was not meet for the Senate, which was
costing the State $250 a day, to waste its time in such frivolity. He
said that in reading the leading newspapers of Chicago and the East, he
found that the Indiana State Legislature had laid itself open to
ridicule by the action already taken on the bill. He thought
consideration of such a proposition was not dignified or worthy of the
Senate. He moved the indefinite postponement of the bill, and the motion
carried.
