 * Invocation count expectation failure messages have been slightly improved
 * When a test case class inherits test methods from a parent class then the TestDox output for such a test case class now starts with test methods from the class that is highest in the inheritance tree (instead of the class that is lowest in the inheritance tree)
 * `TestCase::createStub()`, `TestCase::createStubForIntersectionOfInterfaces()`, and `TestCase::createConfiguredStub()` are now static (and can be used from static data provider methods)
+* The internal methods `__phpunit_*()` have been removed from the `Stub` and `MockObject` interfaces
