Python 3.14.0 alpha 6 is out

Here comes the penultimate alpha.

https://www.python.org/downloads/release/python-3140a6/

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, 3.14.0a6, is the sixth 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:

The next pre-release of Python 3.14 will be the final alpha, 3.14.0a7, currently scheduled for 2025-04-08.

And now for something completely different

March 14 is celebrated as pi day, because 3.14 is an approximation of π. The day is observed by eating pies (savoury and/or sweet) and celebrating π. The first pi day was organised by physicist and tinkerer Larry Shaw of the San Francisco Exploratorium in 1988. It is also the International Day of Mathematics and Albert Einstein’s birthday. Let’s all eat some pie, recite some π, install and test some py, and wish a happy birthday to Albert, Loren and all the other pi day children!

Enjoy the new release

And now for something completely different

2025-01-29 marked the start of a new lunar year, the Year of the Snake 🐍 (and the Year of Python?).

For centuries, π was often approximated as 3 in China. Some time between the years 1 and 5 CE, astronomer, librarian, mathematician and politician Liu Xin (劉歆) calculated π as 3.154.

Around 130 CE, mathematician, astronomer, and geographer Zhang Heng (張衡, 78–139) compared the celestial circle with the diameter of the earth as 736:232 to get 3.1724. He also came up with a formula for the ratio between a cube and inscribed sphere as 8:5, implying the ratio of a square’s area to an inscribed circle is √8:√5. From this, he calculated π as √10 (~3.162).

Third century mathematician Liu Hui (刘徽) came up with an algorithm for calculating π iteratively: calculate the area of a polygon inscribed in a circle, then as the number of sides of the polygon is increased, the area becomes closer to that of the circle, from which you can approximate π.

This algorithm is similar to the method used by Archimedes in the 3rd century BCE and Ludolph van Ceulen in the 16th century CE (see 3.14.0a2 release notes), but Archimedes only went up to a 96-sided polygon (96-gon). Liu Hui went up to a 192-gon to approximate π as 157/50 (3.14) and later a 3072-gon for 3.14159.

Liu Hu wrote a commentary on the book The Nine Chapters on the Mathematical Art which included his π approximations.

In the fifth century, astronomer, inventor, mathematician, politician, and writer Zu Chongzhi (祖沖之, 429–500) used Liu Hui’s algorithm to inscribe a 12,288-gon to compute π between 3.1415926 and 3.1415927, correct to seven decimal places. This was more accurate than Hellenistic calculations and wouldn’t be improved upon for 900 years.

Happy Year of the Snake!

Python 3.13.2 and 3.12.9 now available!

 

A small release day today! That is to say the releases are relatively small; the day itself was of average size, as most days are.

Python 3.13.2

Python 3.13’s second maintenance release. About 250 changes went into this update, and can be yours for free if you just upgrade now.

https://www.python.org/downloads/release/python-3132/

Python 3.12.9

Python 3.12’s ninth maintenance release already. Just 180 changes for 3.12, but it’s still worth upgrading.

Enjoy the new releases

And now for something completely different

In Python, you can use Greek letters as constants. For example:

from math import pi as π

def circumference(radius: float) -> float:
    return 2 * π * radius

print(circumference(6378.137))  # 40075.016685578485

And now for something completely different

A mince pie is a small, round covered tart filled with “mincemeat”, usually eaten during the Christmas season – the UK consumes some 800 million each Christmas. Mincemeat is a mixture of things like apple, dried fruits, candied peel and spices, and originally would have contained meat chopped small, but rarely nowadays. They are often served warm with brandy butter.

According to the Oxford English Dictionary, the earliest mention of Christmas mince pies is by Thomas Dekker, writing in the aftermath of the 1603 London plague, in Newes from Graues-end: Sent to Nobody (1604):

Ten thousand in London swore to feast their neighbors with nothing but plum-porredge, and mince-pyes all Christmas.

Here’s a meaty recipe from Rare and Excellent Receipts, Experienc’d and Taught by Mrs Mary Tillinghast and now Printed for the Use of her Scholars Only (1678):

  1. How to make Mince-pies.

To every pound of Meat, take two pound of beef Suet, a pound of Corrants, and a quarter of an Ounce of Cinnamon, one Nutmeg, a little beaten Mace, some beaten Colves, a little Sack & Rose-water, two large Pippins, some Orange and Lemon peel cut very thin, and shred very small, a few beaten Carraway-seeds, if you love them the Juyce of half a Lemon squez’d into this quantity of meat; for Sugar, sweeten it to your relish; then mix all these together and fill your Pie. The best meat for Pies is Neats-Tongues, or a leg of Veal; you may make them of a leg of Mutton if you please; the meat must be parboyl’d if you do not spend it presently; but if it be for present use, you may do it raw, and the Pies will be the better.

Python 3.13.1, 3.12.8, 3.11.11, 3.10.16 and 3.9.21 are now available

Another big release day! Python 3.13.1 and 3.12.8 were regularly scheduled releases, but they do contain a few security fixes. That makes it a nice time to release the security-fix-only versions too, so everything is as secure as we can make it.

Python 3.13.1

Python 3.13’s first maintenance release. My child is all growed up now, I guess! Almost 400 bugfixes, build improvements and documentation changes went in since 3.13.0, making this the very best Python release to date.

https://www.python.org/downloads/release/python-3131/

Python 3.12.8

Python 3.12 might be slowly reaching middle age, but still received over 250 bugfixes, build improvements and documentation changes since 3.12.7.

Python 3.11.11

I know it’s probably hard to hear, but this is the second security-only release of Python 3.11. Yes, really! Oh yes, I know, I know, but it’s true! Only 11 commits went in since 3.11.10.

Python 3.10.16

Python 3.10 received a total of 14 commits since 3.10.15. Why more than 3.11? Because it needed a little bit of extra attention to keep working with current GitHub practices, I guess.

Python 3.9.21

Python 3.9 isn’t quite ready for pasture yet, as it’s set to receive security fixes for at least another 10 months. Very similarly to 3.10, it received 14 commits since 3.9.20.

Stay safe and upgrade!

As always, upgrading is highly recommended to all users of affected versions.

Enjoy the new releases
