CForth

  • none.

EC

  • reinit AC detect timer when leaving forced discharge mode, to avoid erroneous low-battery power-downs; this mode is only during testing (runin, and battery-capacity tests). EC 0.4.11
  • emit a new event when the power button is released, so a kernel can time the press, EC 0.4.12
  • increase the hard powerdown button press timeout from 2 to 5 seconds to give user-level more flexibility when looking for long presses. EC 0.4.12

Touchscreen

  • none.
