 * Extensions can once again be registered via multiple `@ExtendWith` meta-annotations on
   the same composed annotation on a field within a test class.
+* `@ExtendWith` annotations can now also be repeated when used directly on fields and

 * All `@...Source` annotations of parameterized tests can now also be repeated when used
   as meta annotations.
