Please let me know of any issues.

A previous version 1.1.0.1 was up on our website over the weekend, if you happened to download that you definitely want to replace it.  I discovered a particularly nasty bug when it's used with net-snmnp v5.7.3 which is distributed for Debian 10 "buster".  That version of the net-snmp library assumes the void* context pointer passed for callbacks is a pointer to a 'synch_state' structure, because that's what snmpget/snmpset use, and it then steps on the first 4 bytes of whatever you've passed as the context pointer if the SNMP v3 passphrase or context name are wrong.  That was a lot of fun to track down, fun of the hair-pulling variety.
