==================================

*Release date: 2022-08-01*

Security
--------

- gh-issue-87389: :mod:`http.server`: Fix an open redirection vulnerability

  allocation errors. Patch by Honglin Zhu.

  argument name is an instance of a str subclass with overloaded ``__eq__``
  and ``__hash__``. Previously it could cause SystemError or other undesired
  behavior.

- gh-issue-94949: :func:`ast.parse` will no longer parse parenthesized
  context managers when passed ``feature_version`` less than ``(3, 9)``.
  Patch by Shantanu Jain.

  expressions when passed ``feature_version`` less than ``(3, 8)``. Patch by
  Shantanu Jain.

- gh-issue-94869: Fix the column offsets for some expressions in multi-line
  f-strings :mod:`ast` nodes. Patch by Pablo Galindo.

- gh-issue-91153: Fix an issue where a :class:`bytearray` item assignment
  could crash if it's resized by the new value's :meth:`__index__` method.

  sequences (1000s of elements). Such code failed to compile. It now
  compiles and runs correctly.

  versions where these flags are not present. Patch by Kumar Aditya.

- gh-issue-95166: Fix :meth:`concurrent.futures.Executor.map` to cancel the

  :func:`inspect.isgeneratorfunction`, and
  :func:`inspect.isasyncgenfunction` now properly return ``True`` for
  duck-typed function-like objects like instances of
  :class:`unittest.mock.AsyncMock`.

  ``maxtasksperchild`` is not ``None`` or a positive int.
