+  <li> Fixed: step-32 had a piece of code where we accessed an internal
+  representation of how Trilinos vectors are actually stored. This is poor
+  style and has been rewritten.

   <li> Fixed: ParameterHandler will no longer output an error if the file
   to be read ends with "end" without a newline.
