Sourced from mock's changelog.

5.0.2

• gh-102978: Fixes :func:unittest.mock.patch not enforcing function signatures for methods decorated with @classmethod or @staticmethod when patch is called with autospec=True.

• gh-103329: Regression tests for the behaviour of unittest.mock.PropertyMock were added.

5.0.1

• gh-100740: Fix unittest.mock.Mock not respecting the spec for attribute names prefixed with assert.

• gh-100690: Mock objects which are not unsafe will now raise an AttributeError when accessing an attribute that matches the name of an assertion but without the prefix assert_, e.g. accessing called_once instead of assert_called_once. This is in addition to this already happening for accessing attributes with prefixes assert, assret, asert, aseert, and assrt.

• gh-96127: inspect.signature was raising TypeError on call with mock objects. Now it correctly returns (*args, **kwargs) as infered signature.

5.0.0

• gh-98624: Add a mutex to unittest.mock.NonCallableMock to protect concurrent access to mock attributes.

• bpo-43478: Mocks can no longer be used as the specs for other Mocks. As a result, an already-mocked object cannot have an attribute mocked using autospec=True or be the subject of a create_autospec(...) call. This can uncover bugs in tests since these Mock-derived Mocks will always pass certain tests (e.g. isinstance) and builtin assert functions (e.g. assert_called_once_with) will unconditionally pass.

• bpo-45156: Fixes infinite loop on :func:unittest.mock.seal of mocks created by :func:~unittest.create_autospec.

• bpo-41403: Make :meth:mock.patch raise a :exc:TypeError with a relevant error message on invalid arg. Previously it allowed a cryptic :exc:AttributeError to escape.

• gh-91803: Fix an error when using a method of objects mocked with :func:unittest.mock.create_autospec after it was sealed with :func:unittest.mock.seal function.
