Reporting of "multiple failing examples" now uses the PEP 654
ExceptionGroup type, which is provided by the exceptiongroup backport
on Python 3.10 and earlier (issue #3175).
"hypothesis.errors.MultipleFailures" is therefore deprecated.
Failing examples and other reports are now stored as PEP 678
exception notes, which ensures that they will always appear together
with the traceback and other information about their respective error.
The canonical version of these notes (with links) is on readthedocs.
