I've been using 1.08 for a long time now (since it was "current") and it is very robust, in the sense that if the DHT22 devices are on long wires, v 1.08 still is able to read the device. I upgraded to DHTlib 1.32, and found that, while it could read a DHT22 on short leads (a few inches) it wouldn't read devices that were many feet away. (Don't judge me, I have my reasons.) I found that uncommenting line 185 in dht.cpp, which is:

digitalWrite(pin, HIGH); // T-go

fixes the problem. This seems to me to be a "low cost" way of enhancing the reliability of reading DHT22's when the lead length is "sub optimal". Please consider making this change to your code.

Thanks,
