     The original cyrb53 has a slight mixing bias in the low bits of h1.
     This shouldn't be a huge problem, but I want to try to improve it.
     This new version should have improved avalanche behavior, but
-    it is not quite final, I may still find improvements.
-    So don't expect it to always produce the same output.
+    it is not final, and changes to the algorithm are expected.
+    So don't expect this function to produce the same output in the future!
