+If a test raises an ``ExceptionGroup`` (or nested ``ExceptionGroup``\ s) with only
+a single 'leaf' exception from ``pytest.xfail()`` or ``pytest.skip()``\ , we now
+unwrap it to have the desired effect on Pytest.  ``ExceptionGroup``\ s with two or
+more leaf exceptions, even of the same type, are not changed and will be treated
+as ordinary test failures.
+
+See `pytest-dev/pytest#9680 <https://github.com/pytest-dev/pytest/issues/9680>`__
+for design discussion.  This feature is particularly useful if you've enabled
+`the new strict_exception_groups=True option
+<https://trio.readthedocs.io/en/stable/reference-core.html#strict-versus-loose-exceptiongroup-semantics>`__.
