<h3>Specific improvements</h3>
<ol>
+ <li> Changed: The cells of coarse meshes in
+ parallel::distributed::Triangulation used to be ordered in a Cuthill-McKee
+ numbering, which yields very high surface-to-volume ratios of the individual
+ processors' partition in case the coarse mesh consists of many cells, in
+ particular in 3D. The algorithm now uses SparsityTools::reorder_hierarchical
+ in order to get more compact partitions, similarly to the z-ordering applied
+ by p4est.

+ </li>
+
+ <li> New: There is now a new method
+ GridTools::get_vertex_connectivity_of_cells.
+ <br>
+ (Martin Kronbichler, 2015/04/10)
+ </li>
+
+ <li> New: There is now a new method SparsityTools::reorder_hierarchical to
+ sort nodes of a graph (sparsity pattern) in a z-like way by hierarchical
+ grouping of neighboring nodes.
+ <br>
+ (Martin Kronbichler, 2015/04/10)
+ </li>
+
+ <li> Changed: The methods SparsityTools::reorder_Cuthill_McKee and
+ GridTools::get_face_connectivity_of_cells used to take a SparsityPattern as
+ argument. The data type has been changed to DynamicSparsityPattern in order
+ to avoid copying things around. The old interface is still available but
+ marked as deprecated.

+ (Martin Kronbichler, 2015/04/10)
+ </li>
+
<li> Fixed: Added missing hp-related functions to FE_Q_Hierarchical together with
a couple of unit tests. Improved code comments.

(Denis Davydov, 2015/04/10)
- <li>
+ </li>
<li> Fixed: deal.II did not compile on 32-bit systems when using newer
p4est versions (1.0 and later) due to a type mismatch. This is now fixed.
<br>
(Wolfgang Bangerth, 2015/04/08)
- <li>
+ </li>
<li> Changed: In the spirit of the changes made to the distinction
between Point and Tensor objects discussed above, the first argument
to GridTools::shift() has been changed from a Point to a Tensor@<1,dim@>.
<br>
(Wolfgang Bangerth, 2015/04/02)
- <li>
+ </li>
<li> New: There is now a new quadrature formula in quadrature_lib. It is
now possible to use Telles' quadrature rules through the function QTelles
to integrate singular integrals
<br>
(Nicola Giuliani, 2015/04/01)
- <li>
+ </li>
<li> New: Added FE_Bernstein: a scalar finite element based on Bernstein basis polynomials.
