|
||||
v3.7.11
|
||||
|
||||
4way no longer a seperate feature, included in AVX2.
|
||||
Added x16r algo for Ravencoin, anime algo for Animecoin.
|
||||
More 4way optimizations for X13 and up.
|
||||
Tweaked CPU affinity to better support more than 64 CPUs.
|
||||
Fixed compile problem on some old AMD CPUs.
|

v3.7.10
|
||||
|
||||
