Yes, it would be really nice after so long to release a new miner, if possible without dev fee or reduced. I don't think it can get any faster, maybe very little, or if he write a completely new code - algorithm.
In any case, Claymore is a good coder and miner.
The ZEC hash rate is already very fast. not much to improve.
Not much to improve? You can't be serious. How about lowering the dev fee as promised over 5 months ago? That was on November 18th 2017 to be exact. Perhaps adding support for newer AMD drivers? Also, you say that this miner is very efficient, in comparison to what? There are really only two AMD ZCash GPU miners, Claymore's and Optiminer. Claymore's does win that race by a slim margin, but neither miner has seen an update in quite sometime. There's things to improve and I'd like to see some sort of development being performed for that dev fee I'm paying. Sure I could stop paying the dev fee, but I like supporting Claymore's work. Maybe I'm just asking for to much.
