🐍2️⃣🚀 The **final** release candidate of Python 3.13 is out!

➡️ Library maintainers, please upload wheels to PyPI **now**, especially if you have compiled extensions (there are no more ABI changes), so everything is in place for the big 3.13.0 release in 3 weeks!

🔒 Also! Security releases have been made for the full set of Python 3.8 - 3.12. Please upgrade!

"Call to action

"We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.13 compatibilities during this phase, and where necessary publish Python 3.13 wheels on PyPI to be ready for the final release of 3.13.0. Any binary wheels built against Python 3.13.0rc1 **will work** with future versions of Python 3.13."

🚀🧵🐍 Big thanks to @lysnikolaou of Quansight Labs for helping us get @pillow ready for free-threaded Python 3.13 (we did some work at the @europython sprints).

See https://labs.quansight.org/blog/free-threaded-python-rollout and https://py-free-threading.github.io to learn more.

We also upload nightly free-threaded (cp313t) wheels to help the community test:
https://anaconda.org/scientific-python-nightly-wheels/pillow/

And we'll upload them to PyPI as part of the Q3 release in October.

🐍🧪 Python 3.13 beta 2 is out!

https://discuss.python.org/t/3-13-0b2-now-available/55056

The macOS installer joins the Windows installer in adding an option to install free-threaded binaries as python3.13t, making it even easier to try it out.

See https://github.com/python/cpython/issues/120098 for all the details, and https://dev.to/hugovk/help-us-test-free-threaded-python-without-the-gil-1hgf for an overview.

🐍🧪 Python 3.13.0 is due out in October 2024 and work is underway to implement *experimental support* for PEP 703 "Making the Global Interpreter Lock Optional in CPython".

As the Steering Council noted in their acceptance of the PEP, to succeed it's important to have community support.

I wrote a little guide on how you can help test out the beta in your project, and help us find bugs in CPython:

Okay, time to schedule some major rewrites. I noticed the deprecation warnings when moving platforms to Ubuntu recently, and now the version removing the APIs has been released.

DeprecationWarning: 'cgitb' is deprecated and slated for removal in Python 3.13
DeprecationWarning: 'cgi' is deprecated and slated for removal in Python 3.13

Meanwhile, let's just change the shebang to "python3.12" instead of "python3"...

Just released: Python 3.14.0 release candidate 2! 🚀🐍

🪄 This was planned for 2025-08-26, but we fixed a bug that required bumping the magic number stored in bytecode (.pyc) files

🪄 This means .pyc files created for rc1 will be recompiled for rc2

🪄 The ABI isn’t changing

🪄 Wheels built for rc1 should be fine for rc2, rc3 and 3.14.x

🤖 Did I mention Android binaries?

Dün gece eski python sürümlerinden Python-3.10.15'i ve son sürümü Python-3.13.0'yı indirdim, ama bilgisayarı -yada sâdece python'u- kararsız veya çalışamaz hâle getirmekten korkup vazgeçtim!

Eski kodları çalıştırmak için eski python sürümlerini de ekleme ile ilgili özel yöntemler var, ama henüz daha kolay anlaşılabilir şekilde anlatan bir yer karşıma çıkmadı!

Aslında "kafanı kuma gömmek" gibi olacağından istemiyordum, ama ileriye gidemezsem geri dönmek zorunda kalabilirim!

#python #python313

Python ile ne yapacağımı bilemiyorum!

Henüz daha öğrenmeye yeni başlamış ve bir şeyler yapıyorken kodlarım birden çalışmaz oldu ve nasıl düzelteceğimi öğrenmeye nereden başlayacağımı bile bilmiyorum!

Sanırım Arduino ile oynamaya geri döneceğim!

#python #python313 #arduino

Neden indirdiğim Python kodlarının çoğu çalışmıyor?!

Py5 modülü istedi onu da ekledim, ama hâlâ çalışmıyor!

Ben daha öğrenmeye çalışan bir python öğrencisiyim, neden her şeyi zorlaştırıyorsunuz?

Üstelik İngilizce de bilmiyorum ve bâzan bir ilkokul öğrencisinin bile kolayca anlayabileceği tavsiye ve cevapları anlayamayabiliyorum!

The best way to install Python 3.13 on Ubuntu 24.04? 👀

Just upgrade to Ubuntu 24.10 (Oracular Oriole) and you will find Python 3.13 already packaged for you 🪄

Python 3.12 is also included, so you can continue to use it if you need it 🐍

On October 7, 20204, exactly the same day Python 3.13 was released, the package for Ubuntu 24.10 (which will be released today) was already available ⚡

https://packages.ubuntu.com/oracular/python3.13

Kudos to the maintainers for the great job of packaging Python for Debian and Ubuntu 👏

#Python #Python313 #Debian #Ubuntu #Ubuntu2410 #Oracular #Package #Linux

The rate at which #Python313 is being adopted is the best I've seen. Homebrew added [email protected] within about 24 hours about 24 hours after that it's now the `python3`.

Having said that, Shantanu Jain's analysis of 1,312 packages he depends upon at work shows even better adoption for 3.13 than 3.10-3.12.

Python 3.13 is out! 🚀

https://discuss.python.org/t/python-3-13-0-final-has-been-released/66972?u=hugovk

According to https://pyreadiness.org/3.13/ a little bit of the top 360 packages are ready for 3.13 as for 3.12, but both much more than for 3.11 or 3.10.

It's likely most will work for 3.13, thanks to everyone who tested early.

2024-10-07:
59 packages (16.4%) support 3.13

2023-10-02:
68 packages (18.9%) support 3.12

2022-10-24:
39 packages (10.8%) support 3.11

2021-10-04:
38 packages (10.6%) support 3.10

Python 3.8 is officially EOL 🔚
