i'll put back the q version online, otherwise use a git client on github to get all historical versions.
version b-x to be released soon. it hashes solid on my RX, but i already said such for the b5...

i still use most of my dev time for the cpu version.
TeamRed are great, i think i know how i can achieve low power, but i need time to test. at least i somehow reached equivalent speed, and i've less fees on v8 (0.9 vs 2.5)
but counting the power saving, they're the best.
