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.
