Firmware 2.9.0 released

[booshtukka]

Both my Reactors are now running 2.9.0. I’ve put the latency back down to 60ms and not noticed any instability so far. 

So, nothing new (AirPlay 2 etc) but also exhibiting no issues yet.

Just upgraded. My Right Hand Side Reactor restarted itself during a song for the first time ever with this update.

Hoping no future drop outs. Been OK this morning.
