Trio 0.22.0 (2022-09-28)
------------------------
Headline features
~~~~~~~~~~~~~~~~~
- ``MultiError`` has been deprecated in favor of the standard :exc:`BaseExceptionGroup`
(introduced in :pep:`654`). On Python versions below 3.11, this exception and its
derivative :exc:`ExceptionGroup` are provided by the backport_. Trio still raises
``MultiError``, but it has been refactored into a subclass of :exc:`BaseExceptionGroup`
which users should catch instead of ``MultiError``. Uses of the ``MultiError.filter()``
class method should be replaced with :meth:`BaseExceptionGroup.split`. Uses of the
``MultiError.catch()`` class method should be replaced with either ``except*`` clauses
(on Python 3.11+) or the ``exceptiongroup.catch()`` context manager provided by the
backport_.
See the :ref:`updated documentation <exceptiongroups>` for details.
