Yes, it’s just one line (currently line 107) of the MeterHydros21.h file that contains the most important change, which is this line:  define HYDROS21_MEASUREMENT_TIME_MS 1000

The previous setting was 500 milliseconds but it turns out the new Gen 2 CTD sensors need a full second for measurement time, so changing that line will allow you to use the Gen 2 Hydros21 sensors.
