+  <li><p>New: When Hypre is available as a sub-package of PETSc, the new class
+  PETScWrappers::PreconditionBoomerAMG provides the BoomerAMG implementation
+  of the algebraic multigrid method of the Hypre package as a preconditioner.
+  This functionality is used, for example, in step-40.

   <li><p>New: The class LAPACKFullMatrix now has functions to compute the
