-points to the node points of the corresponding Gauss-Lobatto quadrature
-formula. For degrees one and two, the Gauss-Lobatto quadrature is

-hp::MappingCollection, for example. There are, in addition,
-several places in the library where one would pass a mapping,

-upon construction.
-<br>
-(Sebastian Gonzalez-Pintor, Wolfgang Bangerth, 2016/11/15)
+++ /dev/null
-Fixed: DataOut::build_patches() ignored a higher order
-or Eulerian mapping if no data had previously been attached
-via DataOut::add_data_vector(), i.e., if all that was to be output
-is the mesh itself. This is now fixed.

-Fixed: Objects of type TrilinosWrappers::SparsityPattern::const_iterator

+++ /dev/null
-Improved: The trait class has_vmult_add in linear_operators.h
-has been restricted to test if there is a vmult_add and a Tvmult_add
-method that takes two arguments. This check now also works with
-ICC 13 and ICC 14.

-Changed: To improve readability, TimerOutput::print_summary()
-now simply outputs "0%" if a particular section's time requires
-less than 0.1 per cent of the overall run time.
-<br>
-(Wolfgang Bangerth, 2016/12/03)
+++ /dev/null
-Improved: The run time for the method hp::DoFHandler::distribute_dofs was
-quadratic in the total number of dofs for some grids. This has been fixed.

-(David Wells, 2016/12/07)
+++ /dev/null
-New: The inverse of a rank-2 SymmetricTensor can now be directly computed

-Tensor::invert() function.

-Fixed: ArrayView objects to empty views could not be copied.
-This is now fixed.

-(Wolfgang Bangerth, 2016/12/07)

-New: The ArrayView class now has a default constructor that creates

- Fixed: The DataOutFaces class did not work with parallel triangulations
- if a process had no faces to deal with.

- (Justin Kauffman, Wolfgang Bangerth, 2016/12/15)
-
+++ /dev/null
-Fixed: The SymmetricTensor copy constructor that accepted another

-Improved: ContraintMatrix::distribute_local_to_global now does a bulk write of

-PETScWrappers::MPI::Vector by about 10%.

-(David Wells, 2016/12/21)

-(Daniel Arndt, 2017/01/03)
+++ /dev/null
-Improved: The representation of the two polynomial classes
-Polynomials::Legendre and Polynomials::HermiteInterpolation has been changed
-to the root form, which ensures stable evaluation at high degrees as opposed
-to the coefficient form previously used.
-<br>
-(Martin Kronbichler, 2017/01/03)

-New: LinearOperator now derive from an arbitrary Payload class. This allows

-(Jean-Paul Pelteret, 2017/01/04)
+++ /dev/null
-New: Additional solve() functions have been added to the Trilinos solver

-(Jean-Paul Pelteret, 2017/01/04)
+++ /dev/null
-Fixed: MappingQGeneric, when computing values on a given cell, sometimes reused information computed on a different cell whose faces were curved in a different way. MappingQGeneric now recomputes all values when its order is greater than one (that is, when it can represent curved cells).

-(David Wells, 2017/01/05)

-Fixed: The testsuite now handles paths containing spaces correctly.

-Fixed: PolynomialsABF::compute_n_pols() returned the wrong value in 3d.

-(Wolfgang Bangerth, 2017/01/09)
+++ /dev/null
-Fixed: Copying objects of type PolynomialsABF would lead to memory

+++ /dev/null
-New: The class VectorizedArray has gained two new access functions, gather and
-scatter, that map to more efficient hardware versions on new architectures
-(AVX2 or AVX-512). Furthermore, support for AVX-512 has been improved by
-providing optimized vectorized_load_and_transpose() and
-vectorized_transpose_and_store().
-<br>
-(Martin Kronbichler, 2017/01/11)
+++ /dev/null
-Fixed: LinearAlgebra::distributed::Vector used persistent MPI communicators
-for data exchange, which are not as well-tuned as the usual MPI_Isend and
-MPI_Irecv calls on some implementations, including memory leaks on IBM MPI if
-the communicators are alive over a longer time. Therefore, the communication
-has been changed to non-blocking MPI_Isend and MPI_Irecv calls.
-<br>
-(Martin Kronbichler, 2017/01/11)
+++ /dev/null
-New: There are two new finite elements FE_DGQLegendre and FE_DGQHermite which

-(Martin Kronbichler, 2017/01/11)

-configuration have been addressed, including correct handling of compiler
-flags and preprocessor definitions.

-(Matthias Maier, 2017/01/12)
+++ /dev/null
-Fixed: The FE_ABF class reported the maximal polynomial degree (via
-FiniteElement::degree) for elements of order $r$ as $r+1$, but this is
-wrong. It should be $r+2$ (see Section 5 of the original paper of
-Arnold, Boffi, and Falk). This is now fixed.

-(Wolfgang Bangerth, 2017/01/13)
+++ /dev/null

+++ /dev/null
-Fixed: The GridOut::write_mesh_per_processor_as_vtu() function now works for a mesh whose multilevel hierarchy is not distributed, as well as a mesh whose level_subdomain_ids do not necessarily match its subdomain_ids for every active cell.
-<br>
-(Conrad Clevenger, 2017/02/09)
+++ /dev/null
-Improved: The class FEEvaluation can now also be used without compile-time
-knowledge of the polynomial degree. If the template parameter @p fe_degree is
-set to -1, the degree will be deduced from the underlying finite element. Note
-that performance is 2-3 times slower, though.
-<br>
-(Martin Kronbichler, 2017/02/16)
+++ /dev/null
-Fixed: Fixed a bug in GridTools::laplace_transform() which was previously solving
-for the final position field instead of displacement. The two formulations are
-not equivalent when a non-constant coefficient is provided, which is commonly
-used with displacement formulation.
-<br>
-(Denis Davydov, 2017/02/17)
+++ /dev/null
-Fixed: The DoFAccessor specialization for <code>structdim == 0</code> and
-<code>dimension == 1</code> was missing several definitions, which were

-<br>
-(David Wells, 2017/02/19)
+++ /dev/null
-Fixed: The class MGTransferMatrixFree::clear() did not reset all member

-(Martin Kronbichler, 2017/02/22)
+++ /dev/null
-Fixed: The function AlignedVector::push_back did not work correctly for

+++ /dev/null
-Fixed: The CellSimilarity detection was broken on two corner cases involving
-complicated elements such as FE_RaviartThomas inside an FESystem and when
-preserving an FEValues object using GridTools::transform. These have been
-fixed.
-<br>
-(Martin Kronbichler, 2017/03/07)
+++ /dev/null
-Changed: The parallel triangulation classes parallel::shared::Triangulation
-and parallel::distributed::Triangulation used to duplicate the MPI
-communicator given to the constructor, which could lead to access-after-free
-problems in Trilinos data structures based on this communicator that stayed
-alive longer than the Triangulation. The new implementation simply uses the
-MPI communicator provided by the user and thus avoids these problems. It is
-the user's responsibility to make sure MPI_Comm_free is only called when all
-data structures initialized with it are deleted.
-<br>
-(Martin Kronbichler, 2017/03/08)
+++ /dev/null
-Fixed: By moving a forward declaration of VectorizedArray to a more central

-(Martin Kronbichler, 2017/03/12)
+++ /dev/null
-Improved: The mechanism for placing the additional points of a MappingQ or
-MappingQGeneric between different Manifolds or between an old-style Boundary
-class and the interior StraightBoundary has been reworked. In the new
-implementation, a smoothing algorithm is invoked that interpolates from the
-whole perimeter of a cell's (or a face's) interior in case two or more
-manifolds are adjacent to the cell, like a Boundary object and the
-StraightBoundary in the interior. If only one manifold is present, the new
-points are interpolated from the surrounding vertices only.
-<br>
-(Martin Kronbichler, 2017/03/17)
+++ /dev/null
-New: The Manifold class and derived classes now provide a function
-Manifold::add_new_points that allows to compute multiple new points according
-to a matrix of weights that are appended to the last argument of the
-function. This function is used in MappingQGeneric and can be much more
-efficient for ChartManifold because ChartManifold::pull_back() calls are
-reused for several interpolation operations.
