 >>> RELEASE HISTORY <<<
 
+  June 14th 2014  released Killer Groestl quad version which I deem
+                  sufficiently hard to port over to AMD. It isn't
+                  the fastest option for Compute 3.5 and 5.0 cards,
+                  but it is still much faster than the table based
+                  versions.
+
   May 10th 2014   added X11, but without the bells & whistles
                   (no killer Groestl, SIMD hash quite slow still)
