Aiomqtt

Changed

- **BREAKING CHANGE:** Replace all uses of `asyncio.TimeoutError` with `MqttError`.

Calls to `Client.subscribe`/`unsubscribe`/`publish` will no longer raise `asyncio.TimeoutError.`

The new behaviour makes it easier to reason about, which exceptions the library
throws:

- Wrong input parameters? Raise `ValueError`.
- Network or protocol failures? `MqttError`.
- Broken library state? `RuntimeError`.

Fixed

- Fix how keyword arguments are forwarded in `Client.publish` and `Client.subscribe`.

Fixed

- Remove log call that was erroneously put in while debugging the latest release.

Fixed

- Add missing parameters to `Client.publish`.
- Fix error in `Client.publish` when paho-mqtt publishes immediately.

Initial release.
