==================

Bugfixes
--------

- Fixed creating and updating of MultiDict from a sequence of pairs and keyword arguments. Previously passing a list argument modified it inplace, and other sequences caused an error.
`457 <https://github.com/aio-libs/multidict/issues/457>`_
- Fixed comparing with mapping: an exception raised in the `__len__` method caused raising a SyntaxError.
`459 <https://github.com/aio-libs/multidict/issues/459>`_
- Fixed comparing with mapping: all exceptions raised in the `__getitem__` method were silenced.
`460 <https://github.com/aio-libs/multidict/issues/460>`_
