- Mention (again) that `type.__annotations__` is unsafe. It is now safe when using only classes defined under PEP 649 semantics, but not with classes defined using `from __future__ import annotations`. - Mention that annotations on instances no longer work. There was already an issue about this. - Mention the general changes in the "Porting to Python 3.14" section. - `annotationlib` was proposed by PEP-749, not PEP-649. (cherry picked from commit 7291eab) Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com> Co-authored-by: Emma Smith <emma@emmatyping.dev> Co-authored-by: Carol Willing <carolcode@willingconsulting.com>
