- update to 10.1:
* Made the second parameter of connection handlers optional. It will be
deprecated in the next major release. The request path is available in
the :attr:`~legacy.protocol.WebSocketCommonProtocol.path` attribute of
the first argument.
If you implemented the connection handler of a server as::
async def handler(request, path):
...

You should replace it by::

async def handler(request):
path = request.path # if handler() uses the path argument
...
* Added ``python -m websockets --version``.
* Reverted optimization of default compression settings for clients, mainly to
avoid triggering bugs in poorly implemented servers like `AWS API Gateway`_.
* Mirrored the entire :class:`~asyncio.Server` API
in :class:`~server.WebSocketServer`.
* Improved performance for large messages on ARM processors.
* Documented how to auto-reload on code changes in development.
* Avoided half-closing TCP connections that are already closed.
