Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Define state of new GPIO out pins: Some new GPIO pins were initialized but not used. This may cause some random activations e.g. of the red debug LED. To avoid this the output levels are set to inactive levels (e.g. to LED_OFF)
