Oh, and I have one more changelog note I just remembered:
The timeout that guards against leaving your system in a soft-locked state has been changed from 4 seconds to 30 seconds. This has two obvious consequences:
1) If you do softlock, give it 30 seconds and you may get control back.
2) This MAY help the issue with XC disabling intermittently for some of you. We'll see. Thing is, I don't know how it was getting to that point in the first place, and the idea that the filtering code was not hearing from the XC app for four full seconds is worrisome, but we'll see.
