## Changes between versions 3.2.0 and 3.2.1

1. Fixed: In the `ParameterHandler` class, we leaked 8 or 12 bytes of memory per declared parameter. This is now fixed.
   (WB 2001/11/28)

2. Fixed: he `DoFHandler` class had a memory leak. This is now fixed.
   (WB 2001/11/28)

3. Fixed: The `FilteredMatrix::allocate_tmp_vector` function had a bug with block vectors.
   (WB 2001/11/22)

4. New: example program step-12. Discontinuous Galerkin discretization.
   (RH 2001/11/21)

5. New: The new `CellAccessor::neighbor_of_coarser_neighbor` function returns where to find the present cell from a coarser neighbor.
   (RH 2001/11/21)

6. Fixed: when checking for convergence in linear solvers in `SolverControl::check`, we first checked whether the maximal iteration count was reached, and only then whether the target residual was achieved. In cases, where the target residual was only reached in the very last allowed iteration, this led to a failure notice of the linear solver, rather than to a success message. This is now fixed.
   (WB 2001/11/19)

7. Fixed: an error in the definition of the `SolverMinRes::solve` function prevented its compilation under some circumstances.
   (WB 2001/11/14)

8. Fixed: upon breakdown, the `SolverBicgstab` forgot to increment the iteration counter for the breakdown cycle. This is now fixed.
   (WB 2001/11/14)

9. Fixed: the `DoFTools::make_flux_sparsity_pattern` was implemented in 1d, but not instantiated. This is now fixed.
   (WB 2001/11/14)

10. Fixed: the `GridGenerator::hyper_rectangle` function was broken in 3d.
    (WB 2001/10/26)

11. Fixed: class `SparsityPattern` can handle rows of length zero now. For quadratic matrices, these rows are changed to length one, since a diagonal element must be stored.
    (GK 2001/10/11)

12. Fixed: The `DataOutBase::EpsFlags` class forgot to declare the reverse grey scale function as one possible input for the color function for the `ParameterHandler` class. This is now possible.
    (WB 2001/10/10)

13. Fixed: the iterator category template base class of grid iterators was incorrectly set.
