+   ``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 <https://mail.python.org/archives/list/python-dev@python.org/message/CLVXXPQ2T2LQ5MP2Y53VVQFCXYWQJHKZ/>`__;
+   `announcement for Python 3.11 <https://mail.python.org/archives/list/python-dev@python.org/message/VIZEBX5EYMSYIJNDBF6DMUMZOCWHARSO/>`__).
+   No final decision has been made yet. See also :pep:`563` and :pep:`649`.
