Hotfixes: September 28, 2021

Now you can wirelessly stream your favorite music from your iPhone or Apple TV to any Sonos speaker in the house.

Another new feature is Mono Mode. Mono Mode allows you to stream your music in one channel and it sounds like it is coming from a single speaker.
There is also a new shuffle mode that allows you to create a playlist and shuffle it.
You can also now add songs to a queue and you can reorder the queue while it is playing.
The update also fixes a number of bugs and brings some performance improvements.
