Все главные нововведения Python 3.14: от JIT до инструментов отладки

Представьте: ваш Python-код работает на 30% быстрее благодаря JIT-компиляции, обработка запросов масштабируется на все ядра процессора без ограничений GIL, а отладка высоконагруженных систем происходит в реальном времени, без остановки продакшена. Это не футуристический сценарий “what-if” — это реальность Python 3.14, релиза, который переосмысливает саму природу разработки с высокой производительностью на Python.

Just released! 🚀

flake8-implicit-str-concat 0.6.0

A Flake8 plugin to identify those unjoined strings that a first Black run leaves behind:
"111111111111111111111" "222222222222222222222"

I hear there's another big release tomorrow? This release adds support for Python 3.14 and for once code changes were needed due to AST deprecation removals.

Also drop support for almost-very-nearly-EOL Python 3.9.

Python 3.14 will officially support free-threading

https://docs.python.org/3.14/whatsnew/3.14.html#pep-779-free-threaded-python-is-officially-supported

#HackerNews #Python314 #FreeThreading #Programming #News #PythonDevelopment #PEP779

Just released: Python 3.14.0 beta 3! 🚀🐍

🥧 All the good stuff of b2 but also:

🥧 Free-threaded Python is officially supported! (PEP 779)

🥧 Subinterpreters in the stdlib! (PEP 734)

Do you maintain a Python package? Please test 3.14.

If you find a bug now, we can fix it before October, which helps everyone. And you might find some places in your code to update as well, which helps you.

Yes, let's test our projects with free-threaded in CI! Here's how to do it with GitHub Actions:

And see https://py-free-threading.github.io for more guides.

#FreeThreaded #CI #GitHub #GitHubActions

Exciting news!

PEP 779 ("Criteria for supported status for free-threaded Python") has been accepted, which means free-threaded Python is now a supported build!

We'll drop the "experimental" label already in 3.14 beta 3, due on Tuesday!

Less than one week to:

🥧 Python 3.14 beta! This marks the feature freeze, when we stop adding ~~bugs~~ features and begin a five-month stabilisation period, where we need you to start testing and reporting bugs.

https://peps.python.org/pep-0745/

🕒 Forget 3.14 (please don't, please test), Python 3.15 development begins! Check out the freshly published release PEP (where I make a commitment to release until 2031...):
