Jeremy,

I have one each of the last three generations of iPad up to iPad Air2 and all seem to run just fine with iOS 8.1.1. Indeed subjectively, the oldest of the three devices seems to have improved (load speed) somewhat with 8.1.1 over 8.1. I have not hit any bugs that affect my general use of Core Control on these three devices.

Caveat: I have not looked for bugs, but NONE have presented.

The Sooloos app on my iPhone 5S is another story, as reported elsewhere, iOS 8.x killed it. As a result I uninstalled Sooloos from my phone.
