From cryptomining-blog: There is now an updated version of cgminer based on 3.7.2 (kalroth cgminer 3.7.3) with support for MaxCoins keccak (SHA-3) algorithm that is more stable and optimized than the previously available cgminer 3.6.6 with keccak support. So if you are still using the old version 3.6.6 of cgminer with keccak support, then you better update to the new cgminer 3.7.3 kalroth release for mining MaxCoins (MAX).
Now I'm more confused. I have bamt 1.6, which has kalroth cgminer 3.7.2. Should I upgrade it and how and if I do, can I use the miner just as I used with other coins also?
