PhysiBoard 2.0.6

A notification at night no longer lights the keyboard along with the ring.

• The keyboard stays dark while the ring is lit. The ring turns the screen on, and the
  phone lights the keyboard whenever the screen comes on — so a message at 3am lit the whole
  keyboard up to show a ring that exists precisely so nothing else has to. If you had the
  keyboard backlight set to stay on, it then never went off again. The keyboard is now turned
  off for the ring and put back exactly as it was when the ring ends — whether that is the
  timer running out, a touch, a key, unlocking, or the screen going dark. There is a switch
  for it under Notification ring, on to begin with. It needs the same one-time pairing the
  keyboard backlight setup uses; without that the row says so, rather than offering a setting
  that quietly does nothing.
