Here are the changes since the last release:

* Implemented dual mining (Ethash/Blake2s) for some AMD GPUs (RX580/570/560/480/470/460 and Vega). Use the new -dpool, -dwal, -dpass, -dworker, and -dcoin options to set the Blake2s pool. You can set the secondary coin mining intensity with the -sci option. For more information see the Readme.txt file. Note that the devfee when using dual mining is 0.9% on the ethash coin (there is no devfee on the secondary coin).
* New kernels for most AMD GPUs with better performance and hashrate stability (you may need to run auto-tune again to find the best GT values)
* New kernels for Nvidia GPUs with slightly better hashrate
* Stability improvements in the Linux version
* Support for the latest Windows drivers for AMD GPUs (up to 18.11.2)
* Many other small fixes and improvements

Here is an example command-line to use dual-mining with Nicehash:
