no they havent. sqrl is still committed to releasing their gpu accelerated miner, and personally im sure they will fairly soon, my guess is within a couple weeks but again thats purely my guess.
just some drama going on because mineority shut down rather suddenly. sqrl is not mineority.
Thanks for your answer, i didnt had the time to follow on discord. I think too that sqrl has every Reason to be committed as long as their hardware is not vaporware. The market potential is huge if they achieve their goal (i know that in terms of Hashpower, it would be generally cheaper to buy new GPU to achieve same hahsrate, but in terms of powersavings, Acorn wins in the long run)
