Nathan Goldbaum is part of the Quansight Labs team that's been doing a *huge* amount of work getting the ecosystem ready for free-threaded Python.

Here he shares some of his favourite resources to learn about free-threaded Python:

#Annotations

- https://docs.python.org/3/whatsnew/3.14.html#pep-649-pep-749-deferred-evaluation-of-annotations
- https://discuss.python.org/t/python-3-14-0-final-is-here/104210#:~:text=the%20evaluation%20of%20annotations%20is%20now%20deferred

Instead, annotations are stored in special-purpose annotate functions and **evaluated
only when necessary** (except if from __future__ import annotations is used).

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!
