A longstanding complaint with the Dark Sky API is that we report daily temperatures differently than other services: we report the minimum and maximum temperature during a given date, while other services report the daytime high and overnight low. (Put another way, our service reports temperature extrema between midnight and midnight, while other services report extrema from dawn to dawn.) These two were typically the same for daily high temperatures, but typically off by one day for the daily low temperatures (which usually occur around dawn).

To address this complaint, we have added two new fields to daily data points: temperatureHigh and temperatureLow, which match the calculation methods used by other weather services. (temperatureMin and temperatureMax are still supported, but are now considered deprecated.)

As usual, details may be found in our documentation.
