-* Raise helpful failure message, when requesting parametrized fixture at runtime,
-  e.g. with ``request.getfuncargvalue``. BACKWARD INCOMPAT: Previously these params
-  were simply never defined. So a fixture decorated like ``@pytest.fixture(params=[0, 1, 2])``
-  only ran once. Now a failure is raised. Fixes (`#460`_). Thanks to
-  `@nikratio`_ for bug report, `@RedBeardCode`_ and `@tomviner`_ for the PR.
-
 * Passing a command-line string to ``pytest.main()`` is considered deprecated and scheduled
   for removal in pytest-4.0. It is recommended to pass a list of arguments instead (`#1723`_).
