Actually, that's what he said in his last post here: (No mention of other algos at all, and v8 is not promissed either).
Ok I can test pow8 now. But note that I does not guarantee that I will release new version or that I will do it before upcoming fork, this is free miner now and I'm not going to add any fees again, so check other miners, there are many of them.
Just not respected the people that used this miner for so many years paying taxes to you. You are losing respect too with your mining softwares. Just keep it for yourself,dont worry,there are serious developers that have his promises done. Good bye forever
