@mvn23 should we tag this for 0.108?

Please include a change log of what has changed when upgrading dependencies.

This should not be released without #32408 which was merged into dev earlier today. If that one made it into 0.108, this one can be included as well. I'm not up to date on the merge window for 0.108, sorry.

Please include a change log of what has changed when upgrading dependencies.

Main changes since 0.5b1:

• General code cleanup and linting
• Fixed commands when not connected to the gateway
• Add debug logging when connection is lost
• Send empty report on connection loss
• Make serial writes non-blocking
• Clean up after unfinished connection attempt when disconnecting/reconnecting

108 was cut yesterday, so this will be for 109.
