When the outside temperature is less than -10C the station reports that dewpoint is invalid. This patch allows to ignore only that value instead of ignoring all of the packet contents from the outside sensor (including temperature and humidity).
This is also sort of fixed (the reported dew point values might be invalid) in upstream release 5.20.0, but we can't use his repository because there is no public repository and also he ignores requests on his semi-private bugtracker; so we need to use the source we can trust, and currently jgoerzen's branch is the best source out there.
