Documentation

It was correct at the time, but is a bit confusing now:

PEP 563: Postponed Evaluation of Annotations

...
It will become the default in Python 3.10.

https://docs.python.org/3/whatsnew/3.7.html#pep-563-postponed-evaluation-of-annotations

But this is no longer the case as clarified:

from future import annotations was previously scheduled to become mandatory in Python 3.10, but the Python Steering Council twice decided to delay the change (announcement for Python 3.10; announcement for Python 3.11). No final decision has been made yet. See also PEP 563 and PEP 649.

https://docs.python.org/3/library/__future__.html

Confused me as I learned of PEP 563 via the 3.7 "What's new" link being top search result.
I first assumed it wasn't the issue I was seeing as I'm on 3.11, but turns out it was,
and my issue went away when I added __future__ import 😑

Agree we should change this. We don't normally update old What's New sections, but this is confusing enough that it's important to be as clear as possible. We could use similar wording as in the docs for __future__ (https://docs.python.org/3.10/library/__future__.html#id1). However, that wording also needs to be updated: PEP 649 now has really been accepted and is expected to be implemented in Python 3.13.

PR welcome!

While we can and should update the 3.7 What's New section in the docs for currently maintained releases, keep in mind that Python 3.7 has reached end-of-life and no further changes to its documentation set are possible.
