Version 1.5.0 released!
[1.5.0] Support for more pools.
[1.5.0] Allow again extranonces up to 28 bytes (fixed mining problems with nicehash).
[1.5.0] 1-2% increase in hash speed for device specific kernels.
RX470 virtually unchanged compared to 1.4.0. A couple tenth of a percent at most. (i.e. still ~250sols/s on stock with ubuntu 14.04 and amdgpu-pro 16.50).
Edit : 1.5.0 is not faster per se, but the speed (according to the 60s average) is *much* more constant.
Edit2 : some graph for a 4 rigs 4 gpus cluster.
