From: "Peter E. Berger" <pberger@xxxxxxxxxxx> The firmware has a "build_number" field, though it is apparently unused (according to observations of the three firmware images I have seen and confirmed by Digi Tech Support). This comment describes its structure, in case it is populated in a future release. Signed-off-by: Peter E.
