- Issue #39915: Ensure :attr:`unittest.mock.AsyncMock.await_args_list` has
  call objects in the order of awaited arguments instead of using
  :attr:`unittest.mock.Mock.call_args` which has the last value of the call.
  Patch by Karthikeyan Singaravelan.

4.0.1
-----

- Remove the universal marker from the wheel.

  from that commit and before are included in this release along with the
  subsequent changes listed below.

  __ https://github.com/python/cpython/commit/4a686504eb2bbf69adf78077458508a7ba131667

- Issue #37972: Subscripts to the `unittest.mock.call` objects now receive
  the same chaining mechanism as any other custom attributes, so that the
  following usage no longer raises a `TypeError`:

  call().foo().__getitem__('bar')

  Patch by blhsing

- Issue #38839: Fix some unused functions in tests. Patch by Adam Johnson.

- Issue #39485: Fix a bug in :func:`unittest.mock.create_autospec` that
  would complain about the wrong number of arguments for custom descriptors
  defined in an extension module returning functions.

- Issue #39082: Allow AsyncMock to correctly patch static/class methods

- Issue #38093: Fixes AsyncMock so it doesn't crash when used with
  AsyncContextManagers or AsyncIterators.

- Issue #38859: AsyncMock now returns StopAsyncIteration on the exaustion of
  a side_effects iterable. Since PEP-479 its Impossible to raise a
  StopIteration exception from a coroutine.

- Issue #38163: Child mocks will now detect their type as either synchronous
  or asynchronous, asynchronous child mocks will be AsyncMocks and
  synchronous child mocks will be either MagicMock or Mock (depending on
  their parent type).

- Issue #38473: Use signature from inner mock for autospecced methods
  attached with :func:`unittest.mock.attach_mock`. Patch by Karthikeyan
  Singaravelan.

- Issue #38136: Changes AsyncMock call count and await count to be two
  different counters. Now await count only counts when a coroutine has been
  awaited, not when it has been called, and vice-versa. Update the
  documentation around this.

- Issue #37555: Fix `NonCallableMock._call_matcher` returning tuple instead
  of `_Call` object when `self._spec_signature` exists. Patch by Elizabeth
  Uselton

- Issue #37251: Remove `__code__` check in AsyncMock that incorrectly
  evaluated function specs as async objects but failed to evaluate classes
  with `__await__` but no `__code__` attribute defined as async objects.

- Issue #38669: Raise :exc:`TypeError` when passing target as a string with
  :meth:`unittest.mock.patch.object`.

- Issue #25597: Ensure, if ``wraps`` is supplied to
  :class:`unittest.mock.MagicMock`, it is used to calculate return values
  for the magic methods instead of using the default return values. Patch by
  Karthikeyan Singaravelan.

- Issue #38108: Any synchronous magic methods on an AsyncMock now return a
  MagicMock. Any asynchronous magic methods on a MagicMock now return an
  AsyncMock.

- Issue #21478: Record calls to parent when autospecced object is attached
  to a mock using :func:`unittest.mock.attach_mock`. Patch by Karthikeyan
  Singaravelan.

- Issue #38857: AsyncMock fix for return values that are awaitable types.
  This also covers side_effect iterable values that happend to be awaitable,
  and wraps callables that return an awaitable type. Before these awaitables
  were being awaited instead of being returned as is.

- Issue #38932: Mock fully resets child objects on reset_mock(). Patch by
  Vegard Stikbakke

- Issue #37685: Fixed ``__eq__``, ``__lt__`` etc implementations in some
  classes. They now return :data:`NotImplemented` for unsupported type of
  the other operand. This allows the other operand to play role (for example
  the equality comparison with :data:`~unittest.mock.ANY` will return
  ``True``).

- Issue #37212: :func:`unittest.mock.call` now preserves the order of
  keyword arguments in repr output. Patch by Karthikeyan Singaravelan.

- Issue #37828: Fix default mock name in
  :meth:`unittest.mock.Mock.assert_called` exceptions. Patch by Abraham
  Toriz Cruz.

- Issue #36871: Improve error handling for the assert_has_calls and
  assert_has_awaits methods of mocks. Fixed a bug where any errors
  encountered while binding the expected calls to the mock's spec were
  silently swallowed, leading to misleading error output.

- Issue #21600: Fix :func:`mock.patch.stopall` to stop active patches that
  were created with :func:`mock.patch.dict`.

- Issue #38161: Removes _AwaitEvent from AsyncMock.

- Issue #36871: Ensure method signature is used instead of constructor
  signature of a class while asserting mock object against method calls.
  Patch by Karthikeyan Singaravelan.

  Contributed by Susan Su.

  same way that it is done with return_value.

- Issue #30541: Add new function to seal a mock and prevent the
  automatically creation of child mocks. Patch by Mario Corchero.

- Issue #35022: :class:`unittest.mock.MagicMock` now supports the
  ``__fspath__`` method (from :class:`os.PathLike`).

- Issue #33516: :class:`unittest.mock.MagicMock` now supports the
  ``__round__`` magic method.

- Issue #35512: :func:`unittest.mock.patch.dict` used as a decorator with
  string target resolves the target during function call instead of during
  decorator construction. Patch by Karthikeyan Singaravelan.

- Issue #36366: Calling ``stop()`` on an unstarted or stopped
  :func:`unittest.mock.patch` object will now return `None` instead of
  raising :exc:`RuntimeError`, making the method idempotent. Patch
  byKarthikeyan Singaravelan.

- Issue #35357: Internal attributes' names of unittest.mock._Call and
  unittest.mock.MagicProxy (name, parent & from_kall) are now prefixed with
