I love this program so much. My eyes don't strain at night anymore. I used to insist on losing my JB just to stay current but not anymore! They can pry my f.lux out of my cold dead hands lol... Apple added a setting to reduce the white level in the accessibility settings with iOS 8 but it's a joke it hardly does anything. Also all of the nasty quirks with the buggy third party keyboard API still exist in 8.1.1 (thank you to my friend for letting me test on his device!) so I'm not sure *what* Apple did other than fix some security issues and nerf Pangu. No urgency to update from my perspective.
