 Rake version 0.8.4 is a bug-fix release of rake.
 
+NOTE: The version of Rake that comes with Ruby 1.9 has diverged
+      slightly from the core Rake code base.  Rake 0.8.4 will work
+      with Ruby 1.9, but is not a strict upgrade for the Rake that
+      comes with Ruby 1.9.  A (near) future release of Rake will unify
+      those two codebases.
