+- Issue #35330: When a :class:`Mock` instance was used to wrap an object, if
+  `side_effect` is used in one of the mocks of it methods, don't call the

+  decorator construction. Patch by Karthikeyan Singaravelan.

+  :func:`unittest.mock.patch` object will now return `None` instead of

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

+  Fixed minor typo in test function name.
