 recommended. The icelake build is included in anticipation of Intel eventually
 releasing a desktop CPU with a microarchitecture newer than Skylake.

+Notes about included DLL files:

+Downloading DLL files from alternative sources presents an inherent
+security risk if their source is unknown. All DLL files included have

+
+v3.13.1.1
+
+Fixed Windows crash mining minotaur algo.
+
+Fixed GCC 10 compile again.
+Added -fno-common to testing to be consistent with GCC 10 default.
+
+v3.13.1
+
+Added minotaur algo for Ringcoin.
