+* The following private attributes are not available anymore (`#658 <https://github.com/pytest-dev/pytest-bdd/pull/658>`_):
+  * ``_pytest.reports.TestReport.scenario``; replaced by ``pytest_bdd.reporting.test_report_context`` WeakKeyDictionary (internal use)
+  * ``__scenario__`` attribute of test functions generated by the ``@scenario`` (and ``@scenarios``) decorator; replaced by ``pytest_bdd.scenario.scenario_wrapper_template_registry`` WeakKeyDictionary (internal use)

 Fixed
