1.0.3

------------------

`22 <https://github.com/aio-libs/pytest-aiohttp/issue/22>`_

1.0.2

------------------

- Restore implicit switch to ``asyncio_mode = auto`` if *legacy* mode is detected.

1.0.1

------------------

- Don't implicitly switch from legacy to auto asyncio_mode, the integration doesn't work
well.

1.0.0

------------------

- The plugin is compatible with ``pytest-asyncio`` now.  It uses ``pytest-asyncio`` for
async tests running and async fixtures support, providing by itself only fixtures for
creating aiohttp test server and client.
