NEEDS https://build.opensuse.org/request/show/928040 TO BE REVOKED FIRST.

- Update to 10.0:
- Backwards-incompatible changes
- websockets 10.0 requires Python ≥ 3.7.
- The ``loop`` parameter is deprecated from all APIs.
The ``loop`` parameter is also removed
from `~server.WebSocketServer`. This should be transparent.
- `~client.connect` times out after 10 seconds by default.
You can adjust the timeout with the ``open_timeout`` parameter. Set it to
`None` to disable the timeout entirely.
- The ``legacy_recv`` option is deprecated.
- The signature of `~exceptions.ConnectionClosed` changed.
If you raise `~exceptions.ConnectionClosed` or a subclass, rather
than catch them when websockets raises them, you must change your code.
- A ``msg`` parameter was added to `~exceptions.InvalidURI`.
If you raise `~exceptions.InvalidURI`, rather than catch it when
websockets raises it, you must change your code.
- New features
- websockets 10.0 introduces a Sans-I/O API for easier
integration in third-party libraries.
- Added compatibility with Python 3.10.
- Added `~websockets.broadcast` to send a message to many
clients.
- Added support for reconnecting automatically by using
`~client.connect` as an asynchronous iterator.
- Added ``open_timeout`` to :func:`~client.connect`.
- Documented how to integrate with Django.
- Documented how to deploy websockets in production, with
several options.
- Documented how to authenticate connections.
- Documented how to broadcast messages to many connections.
- Improvements
- Improved logging.
- Optimized default compression settings to reduce memory
usage.
- Optimized processing of client-to-server messages when the
C extension isn't available.
- Supported relative redirects in `~client.connect`.
- Handled TCP connection drops during the opening handshake.
- Made it easier to customize authentication with
`~auth.BasicAuthWebSocketServerProtocol.check_credentials`.
- Provided additional information in
`~exceptions.ConnectionClosed` exceptions.
- Clarified several exceptions or log messages.
- Restructured documentation.
- Improved API documentation.
- Extended FAQ.
- Bug fixes
- Avoided a crash when receiving a ping while the connection
is closing.
- The test suite is temporarily suspended as it is completely
broken (gh#aaugustin/websockets#1081).
