I read elsewhere that the update 'enabled speeds 1, 2 and 3 for recirculation mode', which didn't work before because the air flow was too low for the coils (meaning for air conditioning?). It's not too clear, as you say.
Also, for the Supercharging 'tally', I'd not seen those notes before (since as was said, it's only for after January 15th builds). Does it mean that it does give you a constantly updated total of what you are using (like a gas pump, lol), or only when you are done? It says 'will be updated shortly after you are completed', but that could mean the final total of what you use in all.
