We have another speedup ready, mostly beneficial to GDDR5X cards (Titan X Pascal will go over 600 for sure). Stock GTX 1070 gets 390 Sol/s.

We have decided to release source of miner and open it up to work on every pool in near future. We will prepare full statement why we have decided that.

Regarding linux: somewhere along the line of optimisations, linux version simply stopped working correctly (is giving incorrect results). We do not have enough man power (+ there are holiday times) to track down the issue, but I am sure community will find it and fix once we release the source.
