The old code took air and water temperatures primarily from
dive/divetemperature or secondarily if the previous one didn't have
either one of them from divecomputer/temperature. The new code attempts
to take first air temperature from dive/divetemperature or
diveomputer/temperature and then on a separate run the water
temperature from these both. Thus we should be fine if one temperature
is in dive/divetemperature and the other in divecomputer/temperature.
