 Change Log
 ----------
 
+v3.6.6
+
+added tribus algo for Denarius (DNR)
+
+configure removed from .gitignore. This should allow git clone to compile
+on Windows/mingw.
+
+Fixed CPU temperature monitoring on some CPUs (Linux only).
+
+Fixed a compile error on FreeBSD (unsupported YMMV).
+
 v3.6.5
 
 Cryptonight a little faster.
