Can confirm, three keypads that are plugged in 24/7 received the firmware update this afternoon (4-17-21) and the green lights on all three are now off while plugged in.
I noticed the mode LED (blue for disarmed, red for home and armed) now blinks or flickers once a minute on the keypads. It might have always been that way, but if it was I never noticed it before. It happens very briefly and if you blink you’ll miss it, so maybe I just never noticed it before. I got a stopwatch and timed it and it happens at exactly one minute increments, so it seems intentional.
Edit: Upon closer inspection, the flickering of the mode LEDs is not really at one minute intervals, and appears to just be random and frequent.
