Hub Firmware Release Notes - 19.19

Barely any of my ZigBee devices work - and even those unreliably.
Out of 30+ ZigBee devices I have maybe 2 work. WTF?! Which MORON allows these updates to go out.

Power cycled the hub. Even removed some of them after which I was UNABLE TO ADD THEM AGAIN!

WTF? FIX THIS!!!
