Optiminer is back and releasing update of his miner for win and nix
Yup, and it's slightly faster Claymore's v8.
There is no Optiminer release yet (0.6.0 is old)
0.7.0 will be released in a few hours
I have Optiminer v0.9.0 directly from the author.
Edit: I'm sure he will release it shortly. I can not redistribute it because of the license.
