  +- Added initial support for hypre's mixed integer (mixedint) capability, which
  + uses different data types for local and global indices in order to save memory
  + in large problems. This capability requires that hypre was configured with the
  + --enable-mixedint option. Note that this option is currently tested only in
  + ex1p, ex3p, and ex4p, and may not work in more general settings.

  - Added AlgebraicCeedSolver that does matrix-free algebraic p-multigrid for
  diffusion problems with the Ceed backend.
