+<p style="color:red">
+Following are a few modifications to the library that unfortunately
+are incompatible with previous versions of the library, but which we
+deem necessary for the future maintainability of the
+library. Unfortunately, some of these changes will require
+modifications to application programs. We apologize for the
+inconvenience this causes.
+</p>
+
+<ol>
+
+ <li>Changed: GridTools::distort_random is now deterministic (gives the same
+ distorted mesh when called with the same input Triangulation).
+ <br>
+ (Timo Heister, 2015/07/09)
+ </li>
+
+ <li>Changed: MatrixCreator::create_mass_matrix() took matrix and vector
+ objects where the scalar type of the matrix was a template argument
+ but the scalar type of the vector was always <code>double</code>. This
+ has been changed so that the two always need to match.
+ <br>
+ (Denis Davydov, Wolfgang Bangerth, 2015/06/17)
+ </li>
+
+ <li>Changed: Functions such as FEValuesBase::get_function_values() that
+ extracted the values of functions at the quadrature points of a cell
+ implicitly always assumed that <code>double</code> is a reasonable
+ type to store the result in. This, however, is not true if the solution
+ vector's underlying scalar type was, for example,
+ <code>std::complex@<double@></code>. All of the functions of
+ FEValuesBase as well as of the various FEValuesViews class that extract
+ values from solution vectors have been changed so that they now return
+ their results in vectors that use the same underlying scalar type
+ (float, double, or std::complex) as was used in the solution vector.
+ <br>
+ Most user codes will be entirely unaffected by this because they simply
+ use the default vector types which all store their data as doubles.
+ You may have to adjust your code, though, if you use non-standard
+ types such as Vector@<float@> for solution vectors, or use
+ complex-valued data types. This includes compiling PETSc with
+ complex scalars.
+ <br>
+ (Denis Davydov, 2015/05/08)
+ </li>
+
+ <li>Removed: The generic, templated vmult, Tvmult, etc. -interfaces of
+ LAPACKFullMatrix - they were never implemented.
+ <br>
+ (Matthias Maier, 2015/04/10)
+ </li>
+
+ <li>Removed: SparseDirectUMFPACK::vmult_add and
+ SparseDirectUMFPACK::Tvmult_add - they were never implemented.
+ <br>
+ (Matthias Maier, 2015/04/10)
+ </li>
+
+ <li>Removed: The class NamedData has been removed after it had been
+ superseded by AnyData a while ago. This affects the use of classes
+ in Algorithms and MeshWorker
+ <br>
+ (Guido Kanschat, 2015/04/02)
+ </li>
+
+ <li> Removed: The CMake configuration does not use the variable
+ <code>DEAL_II_CMAKE_MACROS_RELDIR</code> any more. Instead, the fixed
+ location <code>\${DEAL_II_SHARE_RELDIR}/macros</code> is used
+ unconditionally
+ <br>
+ (Matthias Maier, 2015/03/26)
+ </li>
+
+ <li> Changed: The TrilinosWrappers::SparseMatrix::clear_row() function used
+ to call TrilinosWrappers::SparseMatrix::compress() before doing its work,
+ but this is neither efficient nor safe. You will now have to do this
+ yourself after assembling a matrix and before clearing rows.
+ <br>
+ The changes to the function above also affect the
+ MatrixTools::apply_boundary_values() variants that operate on Trilinos
+ matrices.
+ <br>
+ (Wolfgang Bangerth, 2015/03/09)
+ </li>
+
+ <li> Changed: Implicit conversion from Tensor@<1,dim@> to Point@<dim@> was
+ previously possible. This has now been prohibited (but you can still
+ do the conversion with an explicit cast) as such conversions are
+ likely incorrect uses of class Point (which should represent only
+ points in space, i.e., vectors anchored at the origin) whereas Tensor
+ should be used for vectors anchored elsewhere (such as normal vectors,
+ directions, differences between points, etc). The difference in
+ usage between Point and Tensor have now been clarified in the documentation
+ of class Point.
+ <br>
+ (Wolfgang Bangerth, 2015/01/12)
+ </li>
+
+ <li> Changed: The project configuration no longer exports
+ <code>[...]/include/deal.II</code>. Thus it is now mandatory to prefix
+ all includes of deal.II headers with <code>deal.II/</code>, i.e.
+ <code>#include <deal.II/[...]></code>.
+ <br>
+ (Matthias Maier, 2015/01/19)
+ </li>
+
+ <li> Changed: ParameterHandler::leave_subsection() no longer returns a bool
+ indicating if there was a subsection to leave. This never worked in the
+ first place, because an exception was thrown.
+ <br>
+ (Timo Heister, 2015/01/19)
+ </li>
+
+ <li> Changed: Make.global_options was completely redesigned. It still
+ contains Makefile sourcable information, but they now closely mimic the
+ declarative style of deal.IIConfig.cmake. Thus, projects that still use
+ Makefiles that source Make.global_options have to be ported to the new
+ layout.
+ <br>
+ (Matthias Maier, 2015/01/13)
+ </li>
+
+ <li> Removed: The Component <code>compat_files</code> was removed entirely. deal.II
+ now always configures and installs with a somewhat FSHS compliant
+ directory structure. Further, the ancient make_dependencies binary was
+ removed. Either migrate your project to CMake, or port your build system
+ to the new (incompatible) Make.global_options found at
+ <code>\${DEAL_II_SHARE_RELDIR}</code>.
+ <br>
+ (Matthias Maier, 2015/01/13)
+ </li>
+
+ <li> Changed: The two-argument call to the MPI_InitFinalize constructor
+ used to imply that the user wanted only one thread per MPI process. This
+ has been changed and now means that every processor core on the system is
+ used. If you run as many MPI processes as there are processor cores, then
+ this means one thread per MPI process, as before. On the other hand, if you
+ start fewer MPI processes than there are cores, then your program will now
+ be allowed to use more than one thread. You can get the old behavior by
+ setting the third (optional) argument to one.
+ <br>
+ (Wolfgang Bangerth, 2015/01/14)
+ </li>
+
+ <li> Removed: TrilinosWrappers::SparseMatrix copy constructor got removed
+ to be in line with PETSc and dealii::SparseMatrix. You can use reinit()
+ and copy_from().
+ <br>
+ (Timo Heister, 2015/01/12)
+ </li>
+
+ <li> Removed: The following compatibility definitions were removed from
+ <code>include/deal.II/base/config.h.in</code> (replacement in brackets):
+ - DEAL_II_CAN_USE_CXX11 (new: DEAL_II_WITH_CXX11)
+ - DEAL_II_CAN_USE_CXX1X (new: DEAL_II_WITH_CXX11)
+ - DEAL_II_COMPILER_SUPPORTS_MPI (new: DEAL_II_WITH_MPI)
+ - DEAL_II_MAJOR (new: DEAL_II_VERSION_MAJOR)
+ - DEAL_II_MINOR (new: DEAL_II_VERSION_MINOR)
+ - DEAL_II_USE_ARPACK (new: DEAL_II_WITH_ARPACK)
+ - DEAL_II_USE_CXX11 (new: DEAL_II_WITH_CXX11)
+ - DEAL_II_USE_METIS (new: DEAL_II_WITH_METIS)
+ - DEAL_II_USE_MT (new: DEAL_II_WITH_THREADS)
+ - DEAL_II_USE_P4EST (new: DEAL_II_WITH_P4EST)
+ - DEAL_II_USE_PETSC (new: DEAL_II_WITH_PETSC)
+ - DEAL_II_USE_SLEPC (new: DEAL_II_WITH_SLEPC)
+ - DEAL_II_USE_TRILINOS (new: DEAL_II_WITH_TRILINOS)
+ <br>
+ (Matthias Maier, 2015/01/12)
+ </li>
+
+ <li> Removed: The direct Mumps interface through
+ <code>SparseDirectMUMPS</code> has been removed. The MUMPS solver is
+ still available through the Trilinos or PETSc interfaces. Alternatively,
+ there is <code>SparseDirectUMFPACK</code>, which has a similar interface.
+ <br>
+ (Matthias Maier, 2015/01/11)
+ </li>
+
+ <li> Removed: This release removes a number of functions that have long
+ been deprecated and that were previously already marked as
+ deprecated (i.e., they would have yielded warnings by the compiler whenever
+ you tried to use them). In almost all cases, there is a function with same
+ name but different argument list that should be used instead.
+ Specifically, the removed functions and classes are:
+ <br>
+ <em>With headers in <code>deal.II/base/</code>:</em>
+ - ThreadManagement::spawn.
+ - Threads::ThreadCondition and Threads::ThreadMutex.
+ - DataOutBase::create_xdmf_entry with 3 arguments.
+ - DataOutBase::write_hdf5_parallel with 2 arguments.
+ - The versions of FunctionParser::initialize that took a
+ <code>use_degrees</code> or <code>constants</code> argument.
+ The implementation as it is now no longer supports either of
+ these two concepts (since we switched from the FunctionParser
+ library to the muparser library after the deal.II 8.1 release).
+ - GridOutFlags::XFig::level_color.
+ - class BlockList.
+ - The MPI support functions in namespace Utilities and Utilities::System.
+ - Deprecated members of namespace types.
+ - Namespace deal_II_numbers.
+ - MultithreadInfo::n_default_threads.
+ - Table::data.
+
+ <br>
+ <em>With headers in <code>deal.II/lac/</code>:</em>
+ - The deprecated constructors of SparseMIC,
+ SparseILU, and SparseLUDecomposition.
+ - SparseMIC::decompose and SparseILU::decompose.
+ - SparseMIC::reinit and SparseLUDecomposition::reinit.
+ - SparseILU::apply_decomposition.
+ - SparseLUDecomposition::decompose and SparseLUDecomposition::is_decomposed.
+ - The compress() functions without argument in the various vector
+ classes. You should use the versions with a VectorOperation
+ argument instead.
+ - Vector::scale.
+ - TrilinosWrappers::*Vector*::compress with an Epetra_CombineMode
+ argument.
+ - SparsityPattern and ChunkSparsityPattern functions that take an
+ <code>optimize_diagonal</code> argument.
+ - SparsityPattern::partition.
+ - SparsityPattern::get_rowstart_indices and
+ SparsityPattern::get_column_numbers.
+ - SparsityPattern::row_iterator and corresponding row_begin() and row_end()
+ functions.
+ - CompressedSparsityPattern::row_iterator and corresponding row_begin()
+ and row_end() functions.
+ - The typedef CompressedBlockSparsityPattern.
+ - The deprecated constructors of SparsityPattern iterator classes.
+ - The deprecated variants of DoFTools::make_periodicity_constraints.
+ - BlockMatrixArray and BlockTrianglePreconditioner functions that
+ take an explicit VectorMemory object.
+ - The SolverSelector constructor that takes a VectorMemory argument.
+ - The version of parallel::distributed::Vector::compress_finish
+ function that takes a boolean as argument.
+ - The version of BlockVector::scale and
+ parallel::distributed::Vector::scale,
+ parallel::distributed::BlockVector::scale
+ function that takes a scalar as argument.
+ - PreconditionBlock::size.
+ - Classes PreconditionedMatrix and PreconditionLACSolver.
+ - PETScWrappers::VectorBase::update_ghost_values.
+ - PETScWrappers::MPI::Vector constructors and reinit variants.
+ - SparseMatrixIterators::Accessor and SparseMatrixIterators::Iterator
+ constructors.
+ - SparseMatrix::raw_entry and SparseMatrix::global_entry.
+ - The ConstraintMatrix functions that transform a matrix, vector, or
+ linear system into a smaller by not just setting the corresponding
+ rows and columns to zero, but actually shrinking the size of the
+ linear system.
+
+ <br>
+ <em>With headers in <code>deal.II/deal.II/</code>:</em>
+ - GridGenerator::laplace_transformation.
+ - The version of GridGenerator::parallelogram where the corners are given
+ as a rank-2 tensor rather than as an array of points.
+ - GridTools::create_union_triangulation.
+ - GridTools::extract_boundary_mesh.
+ - Triangulation::distort_random.
+ - Triangulation::clear_user_pointers.
+ - The refinement listener concept of the Triangulation class. This
+ approach to getting notified about what happens to triangulations
+ has been superseded by the signals defined by the triangulation
+ class.
+
+ <br>
+ <em>With headers in <code>deal.II/fe/</code>:</em>
+ - In FEValues and related classes, the functions that contain the
+ term <code>2nd_derivatives</code> were removed in favor of those
+ with names containing <code>hessian</code>. Similarly, functions
+ with names including <code>function_grads</code> were removed in
+ favor of those called <code>function_gradients</code>. Finally,
+ the <code>cell_normal_vector</code> functions were replaced by
+ <code>normal_vector</code> ones. In all cases, the new functions
+ have been around for a while.
+ - Mapping::transform_covariant and Mapping::transform_contravariant.
+
+ <br>
+ <em>With headers in <code>deal.II/dofs/</code>:</em>
+ - DoFRenumbering::downstream_dg.
+ - DoFTools::count_dofs_per_component.
+ - DoFTools::make_sparsity_pattern with a vector-of-vector mask.
+
+ <br>
+ <em>With headers in <code>deal.II/multigrid/</code>:</em>
+ - The constructors of classes MGSmoother, MGSmootherRelaxation and
+ MGSmootherPrecondition that take a VectorMemory object.
+ - MGLevelObject::get_minlevel and MGLevelObject::get_maxlevel.
+ - MGConstrainedDoFs::non_refinement_edge_index
+ - MGConstrainedDoFs::at_refinement_edge_boundary
+ - MGTools::count_dofs_per_component.
+ - MGTools::apply_boundary_values.
+ - MGTools::extract_inner_interface_dofs.
+ - Class MGMatrix.
+ - Multigrid::vmult and friends.
+
+ <br>
+ <em>With headers in <code>deal.II/matrix_free/</code>:</em>
+ - Classes FEEvaluationDGP, FEEvaluationGeneral and FEEvaluationGL.
+
+ <br>
+ <em>With headers in <code>deal.II/mesh_worker/</code>:</em>
+ - Deprecated variants of MeshWorker::loop and MeshWorker::integration_loop.
+
+ <br>
+ <em>With headers in <code>deal.II/algorithm/</code>:</em>
+ - Algorithms::ThetaTimestepping::operator().
+ - Algorithms::ThetaTimestepping::initialize.
+ - Algorithms::Newton::initialize.
+
+ <br>
+ <em>With headers in <code>deal.II/numerics/</code>:</em>
+ - TimeDependent::end_sweep (with an argument).
+ - PointValueHistory::mark_locations.
+ - The DataPostprocessor::compute_derived_quantities_scalar and
+ DataPostprocessor::compute_derived_quantities_vector functions without
+ evaluation points. If you have
+ data postprocessor classes implemented in your program that overload these
+ functions, you will have to change it in a way that they overload the
+ functions of same name but with the evaluation point argument instead.
+ <br>
+ This release also removes the deprecated class MGDoFHandler. The
+ functionality of this class had previously been incorporated into
+ the DoFHandler class. Unlike the changes above, if you were still
+ using this class, you will need to do the following changes to
+ your code:
+ - Where you called <code>mg_dof_handler.distribute_dofs()</code>
+ you now also need to explicitly call
+ <code>mg_dof_handler.distribute_mg_dofs()</code>.
+ - If you called <code>mg_dof_handler.begin(level)</code>, you
+ will now have to write this as
+ <code>mg_dof_handler.begin_mg(level)</code> to make clear that
+ you are not just interested in an iterator to a cell on a given
+ level, but in fact to a cell that can access the degrees of
+ freedom on a particular level of a multigrid hierarchy.
+ - The type previously referred to as
+ <code>MGDoFHandler::cell_iterator</code> now corresponds to
+ <code>MGDoFHandler::level_cell_iterator</code>.
+ - Where you previously called DoFRenumbering::component_wise
+ for the entire MGDoFHandler object, you now need to call
+ this function for the DoFHandler object, and then call the
+ same function with the <code>level</code> argument for each
+ of the levels of the triangulation individually.
+ <br>
+ (Wolfgang Bangerth, 2014/12/29-2015/01/22)
+ </li>
+
+ <li> Removed: The config.h file no longer exports HAVE_* definitions.
+ Those are either entirely removed (for the blas/lapack symbols) or
+ renamed to DEAL_II_HAVE_*. This change is done in order to avoid clashes
+ with external projects also exporting HAVE_* definitions in their header
+ files.
+ <br>
+ (Matthias Maier, 2014/12/29)

+
+
+<!-- ----------- GENERAL IMPROVEMENTS ----------------- -->
+
+<a name="general"></a>
+<h3>General</h3>
+
+
+<ol>
+ <li> New: Added the class Functions::Polynomial for representation of polynomials.
+ The new class is derived from the Function class.
+ <br>
+ (Angel Rodriguez, 2015/07/01)
+ </li>
+
+ <li> New: deal.II now supports compilation in C++14 mode, which may be
+ enabled with the CMake option <code>DEAL_II_WITH_CXX14</code>.
+ <br>
+ (David Wells, 2015/06/21)
+ </li>
+
+ <li> New: Implement a modified version of the Kelly error estimator, which
+ effectively provides the boundary residual term for the hp-FEM error estimators.
+ <br>
+ (Denis Davydov, 2015/06/17)
+ </li>
+
+ <li> New: DerivativeForm() now takes an additional optional
+ template argument specifying the type, similarly to Tensor() classes.
+ <br>
+ (Luca Heltai, 2015/05/16)
+ </li>
+
+ <li> New: Utilities::MPI::min() functions.
+ <br>
+ (Timo Heister, 2015/05/12)
+ </li>
+
+ <li> New: A PackagedOperation class that stores computation expressions.
+ The primary purpose of this class is to provide syntactic sugar for vector
+ operations (vector space addition, scalar multiplication, application of a
+ linear operator) while avoiding intermediate storage.
+ <br>
+ (Matthias Maier, 2015/05/10)
+ </li>
+
+ <li> Fixed: Utilities::generate_normal_random_number() will now
+ produce a deterministic sequence of numbers on every thread.
+ Furthermore, it will also work on systems that do not have the
+ <code>rand_r</code> library function, such as Cygwin.
+ <br>
+ (Wolfgang Bangerth, 2015/04/19)
+ </li>
+
+ <li> New: A LinearOperator class that stores the abstract concept of a
+ linear operator. The class is fully compatible with the solver and
+ preconditioner interfaces. The primary purpose of this class is to
+ provide syntactic sugar for complex matrix-vector operations and free the
+ user from having to create, set up and handle intermediate storage
+ locations by hand.
+ <br>
+ (Matthias Maier, 2015/04/08)
+ </li>
+
+ <li> Fixed: There were a number of places in the library where we unconditionally
+ called functions <code>_mm_malloc()/_mm_free()</code> to allocate and free
+ memory with a known alignment. This function, however, is only available on
+ systems with x86 or x64_64 compatible processors. These places have now been
+ replaced by calling <code>posix_memalign()</code> instead, a function that
+ should be more widely available.
+ <br>
+ (Wolfgang Bangerth, 2015/04/15)
+ </li>
+
+ <li> Deprecated: The library uses functions such as CellAccessor::subdomain_id(),
+ TriaAccessor::manifold_id(), etc, but used the deviant spelling
+ TriaAccessor::boundary_indicator(), TriaAccessor::set_boundary_indicator(),
+ TriaAccessor::set_all_boundary_indicators(). These last three functions are now
+ deprecated and have been replaced by TriaAccessor::boundary_id(),
+ TriaAccessor::set_boundary_id(), and TriaAccessor::set_all_boundary_ids() for
+ consistency. Similar, Triangulation::get_boundary_indicators() has been
+ deprecated in favor of Triangulation::get_boundary_ids().
+ <br>
+ (Wolfgang Bangerth, 2015/04/11)
+ </li>
+
+ <li> Changed: All example programs used to have calls to set_boundary()
+ methods to deal with curved boundaries. These have been replaced with
+ the corresponding set_manifold() equivalent.
+ <br>
+ (Luca Heltai, 2015/04/06)
+ </li>
+
+ <li> New: A new flag no_automatic_repartitioning in
+ parallel::distributed::Triangulation will disable the automatic
+ repartitioning when calling execute_coarsening_and_refinement() (or things
+ like refine_global(), ...), resulting in all cells staying on the processor
+ they were before. The new function repartition() will execute the
+ repartitioning as done automatically before.
+ <br>
+ (Timo Heister, 2015/03/22)
+ </li>
+
+ <li> Changed: All (Block)Compressed*SparsityPattern classes got
+ replaced by DynamicSparsityPattern and
+ BlockDynamicSparsityPattern, respectively and all examples now
+ teach the dynamic way of creating dynamic sparsity patterns.
+ <br>
+ (Timo Heister, 2015/03/22)
+ </li>
+
+ <li> Improved: We have traditionally had a large number of exceptions
+ that did not output any useful error message other than the name
+ of the exception class. This name was suggestive of the error that
+ had happened, but did not convey a sufficient amount of information
+ to what happened in many of the places where these kinds of exceptions
+ were used, nor what may have caused the exception, or how it could
+ be avoided. We have gone through many of these places and changed
+ the exception to be much more verbose in what they state about the
+ problem, its origin, and how it may be solved.
+ <br>
+ (Wolfgang Bangerth, 2015/02/28-2015/03/31)
+ </li>
+
+ <li> Changed: We have traditionally used Point@<dim@> to represent points
+ in physical space, i.e., vectors that are anchored at the origin, whereas
+ for vectors anchored elsewhere (e.g., differences between points, normal
+ vectors, gradients, etc) we have used Tensor@<1,dim@>. This has now be
+ made more formal in the documentation but also in the return types of
+ <code>operator-()</code> for Point objects: The difference between two
+ points, <code>p1-p2</code> now returns a Tensor@<1,dim@>. On the other
+ hand, subtracting a Tensor@<1,dim@> object from a Point, <code>p-t</code>,
+ results in a Point@<dim@>.
+ <br>
+ (Wolfgang Bangerth, 2015/02/05)
+ </li>
+
+ <li> New: Examples from 1 to 16 now use the Manifold interface
+ instead of the old Boundary interface to describe curved boundaries
+ and domains.
+ <br>
+ (Luca Heltai, 2015/01/15)
+ </li>
+
+ <li> New: The build system now queries for git branch name and
+ revision sha1 (and automatically reconfigures if necessary). This
+ information is used to annotate summary.log and detailed.log with the
+ current revision sha1. Further, a header file <deal.II/base/revision.h>
+ is now available that exports the macros: DEAL_II_GIT_BRANCH,
+ DEAL_II_GIT_REVISION, DEAL_II_GIT_REVISION_SHORT.
+ <br>
+ (Matthias Maier, 2015/01/02)
+ </li>
+</ol>
+
+
+<!-- ----------- SPECIFIC IMPROVEMENTS ----------------- -->
+
+<a name="specific"></a>
+<h3>Specific improvements</h3>
+
+
+
+<ol>
+ <li>New: parallel::distributed::Triangulation::add_periodicity
+ now allows for arbitrary orientations between matching faces.
+ <br>
+ (Daniel Arndt, 2015/07/12)
+ </li>
+
+ <li> New: Utilities::trim() function removes trailing and leading spaces.
+ <br>
+ (Timo Heister, 2015/07/11)
+ </li>
+
+ <li>Changed: The IsBlockMatrix class is now declared in
+ <code>constraint_matrix.h</code> instead of its former home in
+ <code>block_indices.h</code>.
+ <br>
+ (Wolfgang Bangerth, 2015/07/10)
+ </li>
+
+ <li>New: CellId::to_string() returns a string representation of a CellId object.
+ <br>
+ (Timo Heister, 2015/07/05)
+ </li>
+
+ <li>New: Utilities::replace_in_string().
+ <br>
+ (Timo Heister, 2015/07/05)
+ </li>
+
+ <li>Improved: GridOut::write_vtk() and GridOut::write_vtu() now
+ output material id, level and subdomain ids of the cells.
+ <br>
+ (Guido Kanschat, 2015/07/05)
+ </li>
+
+ <li>Improved: The font scaling in GridOut::write_svg() was broken,
+ since the units were missing. It has been fixed and an additional
+ parameter GridOutFlags::Svg::cell_font_scaling has been introduced
+ for tuning.
+ <br>
+ (Guido Kanschat, 2015/07/04)
+ </li>
+
+ <li> New: VectorizedArray now provides two methods
+ vectorized_load_and_transpose() and vectorized_transpose_and_store() that
+ perform vectorized reads or writes and convert from array-of-struct into
+ struct-of-array or the other way around.
+ <br>
+ (Martin Kronbichler, 2015/07/02)
+ </li>
+
+ <li>New: GridGenerator::cheese() for a mesh with many holes;
+ GridGenerator::simplex() for simplices in 2 and 3 dimensions;
+ GridGenerator::hyper_cross() for crosses in 2 and 3 dimensions.
+ <br>
+ (Guido Kanschat, 2015/07/02)
+ </li>
+
+ <li> Fixed: The specialization of DoFAccessor for zero-dimensional objects,
+ i.e., for vertices as created by accessing the faces of one-dimensional
+ cells, had a member function DoFAccessor::child() that was declared but not
+ implemented. This is now fixed.
+ <br>
+ (Wolfgang Bangerth, 2015/07/01)
+ </li>
+
+ <li> Improved: Functions::Monomial::gradient function now works when both base and exponent
+ are equal to zero for one or more components of the monomial.
+ Also, an assertion is added to avoid exponentiation of negative base numbers with real exponents.
+ <br>
+ (Angel Rodriguez, 2015/06/29)
+ </li>
+
+ <li> Fixed: The function numbers::is_finite() produced incorrect results when
+ called with a NaN number (specifically, it produces an uncatchable floating
+ point exception when called with a signaling NaN). This was clearly not
+ intended since such values are definitely not finite.
+ <br>
+ (Wolfgang Bangerth, 2015/06/29)
+ </li>
+
+ <li> Improved: The SparseMatrix class can now also use <code>std::complex</code>
+ scalars for its elements.
+ <br>
+ (Wolfgang Bangerth, 2015/06/26)
+ </li>
+
+ <li> Improved: FE_DGQArbitraryNodes::get_name() now also detects if
+ the quadrature rule was Gauss points.
+ <br>
+ (Guido Kanschat, 2015/06/22)
+ </li>
+
+ <li> Improved: DoFRenumbering::Cuthill_McKee() can now also
+ use starting indices for parallel triangulations.
+ <br>
+ (Wolfgang Bangerth, 2015/06/11)
+ </li>
+
+ <li> Improved: VectorTools::interpolate now works with FE_Nothing.
+ <br>
+ (Angel Rodriguez, 2015/06/03)
+ </li>
+
+ <li> Improved: deal.II now uses a variety of strategies to silence compiler
+ warnings about unused variables and unused parameters.
+ <br>
+ (David Wells, 2015/04/13)
+ </li>
+
+ <li> New: Add a clear function to the PETSc::Vector
+ and PETSc::MPI::Vector classes similar to the Trilinos vector classes.
+ <br>
+ (Martin Steigemann 2015/05/22)
+ </li>
+
+ <li> New: Three new quadrature formulas in quadrature_lib, based on
+ Chebyshev quadrature rules. See functions QGaussChebyshev,
+ QGaussRadauChebyshev and QGaussLobattoChebyshev.
+ <br>
+ (Giuseppe Pitton, Luca Heltai 2015/05/11)
+ </li>
+
+ <li> Fixed: MatrixOut now also works with Trilinos and PETSc matrices.
+ <br>
+ (Wolfgang Bangerth, 2015/05/11)
+ </li>
+
+ <li> Changed: TrilinosWrappers::Vector, TrilinosWrappers::BlockVector,
+ PETScWrappers::Vector, and PETScWrappers::BlockVector are deprecated. Either
+ use the MPI or the deal.II version of the Vector/BlockVector.
+ <br>
+ (Bruno Turcksin, 2015/05/04)
+ </li>
+
+ <li> Fixed: GridGenerator::half_hyper_shell can now be colorized.
+ <br>
+ (Daniel Arndt, 2015/05/05)
+ </li>
+
+ <li> New: The function VectorTools::point_gradient has been added to compute
+ the gradient of a given FE function.
+ <br>
+ (Daniel Arndt, 2015/05/03)
+ </li>
+
+ <li> New: dealii:Vector, dealii::BlockVector,
+ TrilinosWrappers::MPI::Vector, TrilinosWrappers::MPI::BlockVector,
+ PETScWrappers::MPI::Vector and PETScWrappers::MPI::BlockVector now have
+ move constructors and move assignment operators in C++11 mode.
+ <br>
+ (Matthias Maier, 2015/05/01)
+ </li>
+
+ <li> New: Introduce DoFRenumbering::block_wise for multigrid computation.
+ <br>
+ (Timo Heister, Florian Sonner, 2015/04/30)
+ </li>
+
+ <li> New: There are now MPI sum functions for Tensors and SymmetricTensors
+ in the Utilities::MPI namespace.
+ <br>
+ (Ian Rose, 2015/04/24)
+ </li>
+
+ <li> Fixed: project_boundary_values_curl_conforming_l2() produced incorrect
+ results for non-uniform grids in 2D. Adjustment to the way 2D tangents to edges are
+ computed fixes this.
+ <br>
+ (Ross Kynch, 2015/04/23)
+ </li>
+
+ <li> Fixed: The TimerOutput class reported abnormally large cpu time when run
+ with more than one process with MPI. Now this is fixed.
+ <br>
+ (Lei Qiao, 2015/04/19)
+ </li>
+
+ <li> New: The VectorTools::integrate_difference() function can now
+ also compute the $H_\text{div}$ seminorm, using the
+ VectorTools::NormType::Hdiv_seminorm argument.
+ <br>
+ (Zhen Tao, Arezou Ghesmati, Wolfgang Bangerth, 2015/04/17)
+ </li>
+
+ <li> Fixed: The class SymmetricTensor<2,dim> is now usable also for dim>3.
+ <br>
+ (Martin Kronbichler, 2015/04/14)
+ </li>
+
+ <li> New: The DynamicSparsityPattern class (formerly called
+ CompressedSparsityPattern) now has an iterator class that allows to
+ walk over the nonzero elements of a matrix represented by this class.
+ <br>
+ (Wolfgang Bangerth, 2015/04/13)
+ </li>
+
+ <li> New: The GridGenerator::subdivided_hyper_cube() and
+ GridGenerator::subdivided_hyper_rectangle() now work also for codimension
+ one and two Triangulation;
+ <br>
+ (Luca Heltai, 2015/04/12)
+ </li>
+
+ <li> New: A new VectorTools::get_position_vector() function has been
+ added to the library that allows one to interpolate the Geometry of
+ a (possibly curved) triangulation to vector finite element fields
+ of at least spacedim components.
+ <br>
+ (Luca Heltai, 2015/04/11)
+ </li>
+
+ <li> New: TrilinosWrappers::BlockSparseMatrix now has member functions
+ TrilinosWrappers::BlockSparseMatrix::domain_paritioner() and
+ TrilinosWrappers::BlockSparseMatrix::range_partitioner() that return a
+ vector of the underlying block Epetra_Map.
+ <br>
+ (Matthias Maier, 2015/04/08)
+ </li>
+
+ <li> New: A new MappingFEField() class has been added to the library
+ that generalizes MappingQEulerian to allow arbitrary FiniteElements.
+ <br>
+ (Marco Tezzele, Luca Heltai, 2015/04/06)
+ </li>
+
+ <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.
+ <br>
+ (Martin Kronbichler, 2015/04/10)
+ </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.
+ <br>
+ (Martin Kronbichler, 2015/04/10)
+ </li>
+
+ <li> New: One can now ask a cell the how many-th active cell it is,
+ using CellAccessor::active_cell_index() (which is called as
+ <code>cell-@>active_cell_index()</code>).
+ <br>
+ (Wolfgang Bangerth, 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.
+ <br>
+ (Denis Davydov, 2015/04/10)
+ </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> 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> 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> New: Added FE_Bernstein: a scalar finite element based on Bernstein basis polynomials.
+ <br>
+ (Marco Tezzele, Luca Heltai, 2015/03/31)
+ </li>
+
+ <li> New: A function to get a map with all vertices at boundaries has
+ been added at GridTools::get_all_vertices_at_boundary(). This function
+ will return a map which can be used in functions like
+ GridTools::laplace_transform().
+ <br>
+ (Fernando Posada, 2015/03/31)
+ </li>
+
+ <li> Fixed: TrilinosWrappers::SparseMatrix::local_range() erroneously
+ threw an exception in 64-bit mode. This is now fixed.
+ <br>
+ (Wolfgang Bangerth, 2015/03/24)
+ </li>
+
+ <li> New: The GridOut::write_gnuplot() function produced output
+ for 1d meshes embedded in higher dimensional spaces that was
+ invalid in that the lines showing individual cells were connected.
+ While this is not wrong for singly connected 1d meshes, it leads to wrong
+ results if the domain is not singly connected and not every cell is the
+ right neighbor of the previous cell.
+ <br>
+ (Wolfgang Bangerth, 2015/03/23)
+ </li>
+
+ <li> New: The various file format writers of class GridOut were not
+ instantiated for 1d meshes in 3d space. This is now fixed.
+ <br>
+ (Wolfgang Bangerth, 2015/03/23)
+ </li>
+
+ <li> New: ParameterHandler::declare_alias() allows to define
+ alternate names for parameters. This is primarily intended to allow
+ for backward compatible ways of changing the names of parameters
+ to applications.
+ <br>
+ (Wolfgang Bangerth, 2015/03/22)
+ </li>
+
+ <li> New: GridGenerator::create_triangulation_with_removed_cells() creates
+ a new mesh out of an existing one by dropping individual cells.
+ <br>
+ (Wolfgang Bangerth, 2015/03/13)
+ </li>
+
+ <li> New: Add MueLu preconditioner from Trilinos through the class
+ TrilinosWrappers::PreconditionAMGMueLu. This is a new algebraic
+ multigrid package. The input parameters are almost the same as the ones
+ from ML so that the two preconditioners can be easily swapped.
+ <br>
+ (Bruno Turcksin, 2015/03/11)
+ </li>
+
+ <li> Fixed: Iterating over the elements of a TrilinosWrappers::SparseMatrix
+ object previously led to errors if the matrix was in fact stored in
+ parallel across multiple MPI processes. This is now fixed: rows not
+ stored locally on the processor where you run the iteration simply look
+ like they're empty.
+ <br>
+ (Wolfgang Bangerth, 2015/03/08)
+ </li>
+
+ <li> New: There is now a new macro DeclExceptionMsg that allows to
+ declare an exception that does not take any run-time arguments
+ yet still allows to specify an error message.
+ <br>
+ (Wolfgang Bangerth, 2015/02/27)
+ </li>
+
+ <li> New: There is now a class std_cxx11::unique_ptr that provides
+ the functionality of std::unique_ptr in C++11 mode, and that
+ provides an emulation for older compilers.
+ <br>
+ (Wolfgang Bangerth, 2015/02/22)
+ </li>
+
+ <li> New: IndexSet now has a local typedef IndexSet::value_type.
+ <br>
+ (Wolfgang Bangerth, 2015/02/22)
+ </li>
+
+ <li> New: FE_TraceQ can now also be used in 1D.
+ <br>
+ (Martin Kronbichler, 2015/02/21)
+ </li>
+
+ <li> New: FE_TraceQ now implements get_face_interpolation_matrix and
+ get_subface_interpolation_matrix, enabling
+ DoFTools::make_hanging_node_constraints on this element.
+ <br>
+ (Anton Evgrafov, 2015/02/21)
+ </li>
+
+ <li> Fixed: MappingQEulerian would previously not move interior points
+ in 1D for higher order mappings. This has been fixed by removing a few
+ specializations of MappingQ for 1D that are no longer necessary.
+ <br>
+ (Martin Kronbichler, 2015/02/19)
+ </li>
+
+ <li> Fixed: The implementation of the class GrowingVectorMemory has been
+ moved from source/lac/vector_memory.cc to the new file
+ include/deal.II/lac/vector_memory.templates.h. This allows users to
+ create instantiations of GrowingVectorMemory for their own vector classes
+ in case they intend to use them for the deal.II solvers.
+ <br>
+ (Martin Kronbichler, 2015/02/18)
+ </li>
+
+ <li> Changed: All members of MultithreadInfo are now static so it is no
+ longer necessary to use the global instance multithread_info (now
+ deprecated) or create your own instance (which does not work correctly
+ anyway).
+ <br>
+ (Timo Heister, 2015/02/13)
+ </li>
+
+ <li> Fixed: There was a bug in the energy source term of step-33 whereby
+ the term was erroneously multiplied by the density. This is now fixed.
+ <br>
+ (Praveen C, Lei Qiao, 2015/02/13)
+ </li>
+
+ <li> Changed: If you take the product of a Tensor and a scalar number,
+ you previously got a Tensor back that stored its elements in the same
+ data type as the original tensor. This leads to problems if you
+ multiply a <code>Tensor@<1,dim,double@></code> by a
+ <code>std::complex@<double@></code> because the result clearly needs
+ to store its elements as complex numbers, rather than as double
+ variables. This is now changed: The result of the product of a Tensor
+ and a scalar number is now a Tensor that stores its elements in a data
+ type appropriate for this product. The same approach is taken for the
+ SymmetricTensor class.
+ <br>
+ (Wolfgang Bangerth, 2015/02/11)
+ </li>
+
+ <li> New: There is now a new class ProductType that can be used
+ to infer the type of the product of two objects. There is now also
+ a class EnableIfScalar that helps restrict some templates to only
+ cases where a type is a scalar.
+ <br>
+ (Wolfgang Bangerth, 2015/02/04)
+ </li>
+
+ <li> New: The Tensor classes now have copy constructors and copy
+ operators that allow assignment from other tensors with different
+ underlying scalar types.
+ <br>
+ (Denis Davydov, 2015/02/03)
+ </li>
+
+ <li> New: Class hp::DoFHandler can now also be serialized.
+ <br>
+ (Lukas Korous, 2015/01/31)
+ </li>
+
+ <li> Bugfix: deal.II now correctly links against librt in case of bundled
+ boost being used.
+ <br>
+ (Matthias Maier, 2015/01/27)
+ </li>
+
+ <li> New: A new macro <code>DEAL_II_QUERY_GIT_INFORMATION</code> is
+ provided to query user projects for git repository information simmilarly
+ to those exported by deal.II.
+ <br>
+ (Matthias Maier, 2015/01/21)
+ </li>
+
+ <li> Fixed: FEFaceValues and FESubfaceValues did not fill the
+ jacobians and inverse jacobians if requested via the update flags.
+ This is now fixed.
+ <br>
+ (Martin Kronbichler, 2015/01/23)
+ </li>
+
+ <li> Fixed: ParameterHandler::read_input() now checks that
+ 'subsection'/'end' are balanced in the input.
+ <br>
+ (Timo Heister, 2015/01/19)
+ </li>
+
+ <li> Fixed: In 3d, when you set the <code>colorize</code> flag of
+ GridGenerator::hyper_shell(), the faces of the domain were colored but
+ the edges were not. This was an oversight because to refine correctly,
+ the edges also have to have the appropriate boundary indicator set.
+ <br>
+ (Wolfgang Bangerth, 2015/01/16)
+ </li>
+
+ <li> New: dealii::multithread_info.n_cpus returns the correct number of CPU
+ on FreeBSD.
+ <br>
+ (Bruno Turcksin, 2015/01/14)
+ </li>
+
+ <li> Improved: MPI collective operations such as MPI::sum, MPI::max now
+ check for job_supports_mpi() internally, which allows running them also
+ without a call to MPI_Init.
+ <br>
+ (Martin Kronbichler, 2015/01/13)
+ </li>
+
+ <li> Changed: The method job_supports_mpi() now resides in the namespace
+ Utilities::MPI instead of Utilities::System for consistency with other MPI
+ methods. The old method has been marked deprecated and will be removed in
+ a future version.
+ <br>
+ (Martin Kronbichler, 2015/01/13)
+ </li>
+
+ <li> Fixed: The update of ghost values in parallel::distributed::Vector when
+ calling the assignment operator is now active when one of the two vector had
+ its ghost values updated before or when the layout of the right hand side
+ vector is one-to-one, more consistent with parallel PETSc and Trilinos
+ vectors.
+ <br>
+ (Martin Kronbichler, 2015/01/13)
+ </li>
+
+ <li> New: PETScWrappers::MPI::SparseMatrix::reinit(other) copies
+ the layout of another matrix. TrilinosWrappers::SparseMatrix
+ operator= and copy constructor are now disabled. This brings
+ functionality between PETSc and Trilinos in line.
+ <br>
+ (Timo Heister, 2015/01/12)
+ </li>
+
+ <li> New: Triangulation::set_all_manifold_ids() and
+ Triangulation::set_all_manifold_ids_on_boundaries()
+ set all manifold ids on every object or on every
+ boundary object respectively.
+ <br>
+ (Luca Heltai, 2015/01/12)
+ </li>
+
+ <li> New: GridTools::copy_boundary_to_manifold_id() and
+ GridTools::copy_material_to_manifold_id() copy
+ boundary_ids and material_ids to manifold_ids for
+ faces on the boundary and for cells respectively.
+ <br>
+ (Luca Heltai, 2015/01/09)
+ </li>
+
+ <li> Fixed: Utilities::int_to_string() produced wrong results if
+ the number of digits specified was ten or greater.
+ <br>
+ (David Wells, 2015/01/08)
+ </li>
+
+ <li> Fixed: VectorTools::interpolate_to_different_mesh() was accidentally
+ only instantiated for dealii::Vector arguments, rather than all vector
+ classes. This is now fixed.
+ <br>
+ (Benjamin Brands, Wolfgang Bangerth, 2014/12/29)
+ </li>
+
+ <li> Fixed: Use CASROOT environment variable as additional hint for
+ opencasacade.
+ <br>
+ (Matthias Maier, 2014/12/29)
+ </li>
+
+ <li> Fixed: Update the run_testsuite.cmake script to also pick up
+ muparser and opencascade configuration.
+ <br>
+ (Matthias Maier, 2014/12/29)
+ </li>
+
+ <li> Fixed: Update several places in the documentation that were not
+ updated from functionparser to muparser. Add several forgotten
+ DEAL_II_WITH_* variables to certain places in the documentation.
+ <br>
+ (Matthias Maier, 2014/12/29)

<ol>
- <li>Changed: GridTools::distort_random is now deterministic (gives the same
- distorted mesh when called with the same input Triangulation).
- <br>
- (Timo Heister, 2015/07/09)
- </li>
-
- <li>Changed: MatrixCreator::create_mass_matrix() took matrix and vector
- objects where the scalar type of the matrix was a template argument
- but the scalar type of the vector was always <code>double</code>. This
- has been changed so that the two always need to match.
- <br>
- (Denis Davydov, Wolfgang Bangerth, 2015/06/17)
- </li>
-
- <li>Changed: Functions such as FEValuesBase::get_function_values() that
- extracted the values of functions at the quadrature points of a cell
- implicitly always assumed that <code>double</code> is a reasonable
- type to store the result in. This, however, is not true if the solution
- vector's underlying scalar type was, for example,
- <code>std::complex@<double@></code>. All of the functions of
- FEValuesBase as well as of the various FEValuesViews class that extract
- values from solution vectors have been changed so that they now return
- their results in vectors that use the same underlying scalar type
- (float, double, or std::complex) as was used in the solution vector.
- <br>
- Most user codes will be entirely unaffected by this because they simply
- use the default vector types which all store their data as doubles.
- You may have to adjust your code, though, if you use non-standard
- types such as Vector@<float@> for solution vectors, or use
- complex-valued data types. This includes compiling PETSc with
- complex scalars.
- <br>
- (Denis Davydov, 2015/05/08)
- </li>
-
- <li>Removed: The generic, templated vmult, Tvmult, etc. -interfaces of
- LAPACKFullMatrix - they were never implemented.
- <br>
- (Matthias Maier, 2015/04/10)
- </li>
-
- <li>Removed: SparseDirectUMFPACK::vmult_add and
- SparseDirectUMFPACK::Tvmult_add - they were never implemented.
- <br>
- (Matthias Maier, 2015/04/10)
- </li>
-
- <li>Removed: The class NamedData has been removed after it had been
- superseded by AnyData a while ago. This affects the use of classes
- in Algorithms and MeshWorker
- <br>
- (Guido Kanschat, 2015/04/02)
- </li>
-
- <li> Removed: The CMake configuration does not use the variable
- <code>DEAL_II_CMAKE_MACROS_RELDIR</code> any more. Instead, the fixed
- location <code>\${DEAL_II_SHARE_RELDIR}/macros</code> is used
- unconditionally
- <br>
- (Matthias Maier, 2015/03/26)
- </li>
-
- <li> Changed: The TrilinosWrappers::SparseMatrix::clear_row() function used
- to call TrilinosWrappers::SparseMatrix::compress() before doing its work,
- but this is neither efficient nor safe. You will now have to do this
- yourself after assembling a matrix and before clearing rows.
- <br>
- The changes to the function above also affect the
- MatrixTools::apply_boundary_values() variants that operate on Trilinos
- matrices.
- <br>
- (Wolfgang Bangerth, 2015/03/09)
- </li>
-
- <li> Changed: Implicit conversion from Tensor@<1,dim@> to Point@<dim@> was
- previously possible. This has now been prohibited (but you can still
- do the conversion with an explicit cast) as such conversions are
- likely incorrect uses of class Point (which should represent only
- points in space, i.e., vectors anchored at the origin) whereas Tensor
- should be used for vectors anchored elsewhere (such as normal vectors,
- directions, differences between points, etc). The difference in
- usage between Point and Tensor have now been clarified in the documentation
- of class Point.
- <br>
- (Wolfgang Bangerth, 2015/01/12)
- </li>
-
- <li> Changed: The project configuration no longer exports
- <code>[...]/include/deal.II</code>. Thus it is now mandatory to prefix
- all includes of deal.II headers with <code>deal.II/</code>, i.e.
- <code>#include <deal.II/[...]></code>.
- <br>
- (Matthias Maier, 2015/01/19)
- </li>
-
- <li> Changed: ParameterHandler::leave_subsection() no longer returns a bool
- indicating if there was a subsection to leave. This never worked in the
- first place, because an exception was thrown.
- <br>
- (Timo Heister, 2015/01/19)
- </li>
-
- <li> Changed: Make.global_options was completely redesigned. It still
- contains Makefile sourcable information, but they now closely mimic the
- declarative style of deal.IIConfig.cmake. Thus, projects that still use
- Makefiles that source Make.global_options have to be ported to the new
- layout.
- <br>
- (Matthias Maier, 2015/01/13)
- </li>
-
- <li> Removed: The Component <code>compat_files</code> was removed entirely. deal.II
- now always configures and installs with a somewhat FSHS compliant
- directory structure. Further, the ancient make_dependencies binary was
- removed. Either migrate your project to CMake, or port your build system
- to the new (incompatible) Make.global_options found at
- <code>\${DEAL_II_SHARE_RELDIR}</code>.
- <br>
- (Matthias Maier, 2015/01/13)
- </li>
-
- <li> Changed: The two-argument call to the MPI_InitFinalize constructor
- used to imply that the user wanted only one thread per MPI process. This
- has been changed and now means that every processor core on the system is
- used. If you run as many MPI processes as there are processor cores, then
- this means one thread per MPI process, as before. On the other hand, if you
- start fewer MPI processes than there are cores, then your program will now
- be allowed to use more than one thread. You can get the old behavior by
- setting the third (optional) argument to one.
- <br>
- (Wolfgang Bangerth, 2015/01/14)
- </li>
-
- <li> Removed: TrilinosWrappers::SparseMatrix copy constructor got removed
- to be in line with PETSc and dealii::SparseMatrix. You can use reinit()

- (Matthias Maier, 2015/01/12)
- </li>
-
- <li> Removed: The direct Mumps interface through
- <code>SparseDirectMUMPS</code> has been removed. The MUMPS solver is
- still available through the Trilinos or PETSc interfaces. Alternatively,
- there is <code>SparseDirectUMFPACK</code>, which has a similar interface.
- <br>
- (Matthias Maier, 2015/01/11)
- </li>
-
- <li> Removed: This release removes a number of functions that have long
- been deprecated and that were previously already marked as
- deprecated (i.e., they would have yielded warnings by the compiler whenever
- you tried to use them). In almost all cases, there is a function with same
- name but different argument list that should be used instead.
- Specifically, the removed functions and classes are:
- <br>
- <em>With headers in <code>deal.II/base/</code>:</em>
- - ThreadManagement::spawn.
- - Threads::ThreadCondition and Threads::ThreadMutex.
- - DataOutBase::create_xdmf_entry with 3 arguments.
- - DataOutBase::write_hdf5_parallel with 2 arguments.
- - The versions of FunctionParser::initialize that took a
- <code>use_degrees</code> or <code>constants</code> argument.
- The implementation as it is now no longer supports either of
- these two concepts (since we switched from the FunctionParser
- library to the muparser library after the deal.II 8.1 release).
- - GridOutFlags::XFig::level_color.
- - class BlockList.
- - The MPI support functions in namespace Utilities and Utilities::System.
- - Deprecated members of namespace types.
- - Namespace deal_II_numbers.
- - MultithreadInfo::n_default_threads.
- - Table::data.
-
- <br>
- <em>With headers in <code>deal.II/lac/</code>:</em>
- - The deprecated constructors of SparseMIC,
- SparseILU, and SparseLUDecomposition.
- - SparseMIC::decompose and SparseILU::decompose.
- - SparseMIC::reinit and SparseLUDecomposition::reinit.
- - SparseILU::apply_decomposition.
- - SparseLUDecomposition::decompose and SparseLUDecomposition::is_decomposed.
- - The compress() functions without argument in the various vector
- classes. You should use the versions with a VectorOperation
- argument instead.
- - Vector::scale.
- - TrilinosWrappers::*Vector*::compress with an Epetra_CombineMode
- argument.
- - SparsityPattern and ChunkSparsityPattern functions that take an
- <code>optimize_diagonal</code> argument.
- - SparsityPattern::partition.
- - SparsityPattern::get_rowstart_indices and
- SparsityPattern::get_column_numbers.
- - SparsityPattern::row_iterator and corresponding row_begin() and row_end()
- functions.
- - CompressedSparsityPattern::row_iterator and corresponding row_begin()
- and row_end() functions.

- - The deprecated constructors of SparsityPattern iterator classes.
- - The deprecated variants of DoFTools::make_periodicity_constraints.
- - BlockMatrixArray and BlockTrianglePreconditioner functions that
- take an explicit VectorMemory object.
- - The SolverSelector constructor that takes a VectorMemory argument.
- - The version of parallel::distributed::Vector::compress_finish
- function that takes a boolean as argument.
- - The version of BlockVector::scale and
- parallel::distributed::Vector::scale,
- parallel::distributed::BlockVector::scale
- function that takes a scalar as argument.
- - PreconditionBlock::size.
- - Classes PreconditionedMatrix and PreconditionLACSolver.
- - PETScWrappers::VectorBase::update_ghost_values.
- - PETScWrappers::MPI::Vector constructors and reinit variants.
- - SparseMatrixIterators::Accessor and SparseMatrixIterators::Iterator
- constructors.
- - SparseMatrix::raw_entry and SparseMatrix::global_entry.
- - The ConstraintMatrix functions that transform a matrix, vector, or
- linear system into a smaller by not just setting the corresponding
- rows and columns to zero, but actually shrinking the size of the
- linear system.
-
- <br>
- <em>With headers in <code>deal.II/deal.II/</code>:</em>
- - GridGenerator::laplace_transformation.
- - The version of GridGenerator::parallelogram where the corners are given
- as a rank-2 tensor rather than as an array of points.
- - GridTools::create_union_triangulation.
- - GridTools::extract_boundary_mesh.
- - Triangulation::distort_random.
- - Triangulation::clear_user_pointers.
- - The refinement listener concept of the Triangulation class. This
- approach to getting notified about what happens to triangulations
- has been superseded by the signals defined by the triangulation
- class.
-
- <br>
- <em>With headers in <code>deal.II/fe/</code>:</em>
- - In FEValues and related classes, the functions that contain the
- term <code>2nd_derivatives</code> were removed in favor of those
- with names containing <code>hessian</code>. Similarly, functions
- with names including <code>function_grads</code> were removed in
- favor of those called <code>function_gradients</code>. Finally,
- the <code>cell_normal_vector</code> functions were replaced by
- <code>normal_vector</code> ones. In all cases, the new functions
- have been around for a while.
- - Mapping::transform_covariant and Mapping::transform_contravariant.
-
- <br>
- <em>With headers in <code>deal.II/dofs/</code>:</em>
- - DoFRenumbering::downstream_dg.
- - DoFTools::count_dofs_per_component.
- - DoFTools::make_sparsity_pattern with a vector-of-vector mask.
-
- <br>
- <em>With headers in <code>deal.II/multigrid/</code>:</em>
- - The constructors of classes MGSmoother, MGSmootherRelaxation and
- MGSmootherPrecondition that take a VectorMemory object.
- - MGLevelObject::get_minlevel and MGLevelObject::get_maxlevel.
- - MGConstrainedDoFs::non_refinement_edge_index
- - MGConstrainedDoFs::at_refinement_edge_boundary
- - MGTools::count_dofs_per_component.
- - MGTools::apply_boundary_values.
- - MGTools::extract_inner_interface_dofs.
- - Class MGMatrix.
- - Multigrid::vmult and friends.
-
- <br>
- <em>With headers in <code>deal.II/matrix_free/</code>:</em>
- - Classes FEEvaluationDGP, FEEvaluationGeneral and FEEvaluationGL.
-
- <br>
- <em>With headers in <code>deal.II/mesh_worker/</code>:</em>
- - Deprecated variants of MeshWorker::loop and MeshWorker::integration_loop.
-
- <br>
- <em>With headers in <code>deal.II/algorithm/</code>:</em>
- - Algorithms::ThetaTimestepping::operator().
- - Algorithms::ThetaTimestepping::initialize.
- - Algorithms::Newton::initialize.
-
- <br>
- <em>With headers in <code>deal.II/numerics/</code>:</em>
- - TimeDependent::end_sweep (with an argument).
- - PointValueHistory::mark_locations.
- - The DataPostprocessor::compute_derived_quantities_scalar and
- DataPostprocessor::compute_derived_quantities_vector functions without
- evaluation points. If you have
- data postprocessor classes implemented in your program that overload these
- functions, you will have to change it in a way that they overload the
- functions of same name but with the evaluation point argument instead.
- <br>
- This release also removes the deprecated class MGDoFHandler. The
- functionality of this class had previously been incorporated into
- the DoFHandler class. Unlike the changes above, if you were still
- using this class, you will need to do the following changes to
- your code:
- - Where you called <code>mg_dof_handler.distribute_dofs()</code>
- you now also need to explicitly call
- <code>mg_dof_handler.distribute_mg_dofs()</code>.
- - If you called <code>mg_dof_handler.begin(level)</code>, you
- will now have to write this as
- <code>mg_dof_handler.begin_mg(level)</code> to make clear that
- you are not just interested in an iterator to a cell on a given
- level, but in fact to a cell that can access the degrees of
- freedom on a particular level of a multigrid hierarchy.
- - The type previously referred to as
- <code>MGDoFHandler::cell_iterator</code> now corresponds to
- <code>MGDoFHandler::level_cell_iterator</code>.
- - Where you previously called DoFRenumbering::component_wise
- for the entire MGDoFHandler object, you now need to call
- this function for the DoFHandler object, and then call the
- same function with the <code>level</code> argument for each
- of the levels of the triangulation individually.

- (Wolfgang Bangerth, 2014/12/29-2015/01/22)
- </li>
-
- <li> Removed: The config.h file no longer exports HAVE_* definitions.
- Those are either entirely removed (for the blas/lapack symbols) or
- renamed to DEAL_II_HAVE_*. This change is done in order to avoid clashes
- with external projects also exporting HAVE_* definitions in their header
- files.

<ol>
- <li> New: Added the class Functions::Polynomial for representation of polynomials.
- The new class is derived from the Function class.
- <br>
- (Angel Rodriguez, 2015/07/01)
- </li>
-
- <li> New: deal.II now supports compilation in C++14 mode, which may be
- enabled with the CMake option <code>DEAL_II_WITH_CXX14</code>.
- <br>
- (David Wells, 2015/06/21)
- </li>
-
- <li> New: Implement a modified version of the Kelly error estimator, which
- effectively provides the boundary residual term for the hp-FEM error estimators.
- <br>
- (Denis Davydov, 2015/06/17)
- </li>
-
- <li> New: DerivativeForm() now takes an additional optional
- template argument specifying the type, similarly to Tensor() classes.
- <br>
- (Luca Heltai, 2015/05/16)
- </li>
-
- <li> New: Utilities::MPI::min() functions.
- <br>
- (Timo Heister, 2015/05/12)
- </li>
- <li> New: A PackagedOperation class that stores computation expressions.
- The primary purpose of this class is to provide syntactic sugar for vector
- operations (vector space addition, scalar multiplication, application of a
- linear operator) while avoiding intermediate storage.
- <br>
- (Matthias Maier, 2015/05/10)
- </li>
-
- <li> Fixed: Utilities::generate_normal_random_number() will now
- produce a deterministic sequence of numbers on every thread.
- Furthermore, it will also work on systems that do not have the
- <code>rand_r</code> library function, such as Cygwin.
- <br>
- (Wolfgang Bangerth, 2015/04/19)
- </li>
-
- <li> New: A LinearOperator class that stores the abstract concept of a
- linear operator. The class is fully compatible with the solver and
- preconditioner interfaces. The primary purpose of this class is to
- provide syntactic sugar for complex matrix-vector operations and free the
- user from having to create, set up and handle intermediate storage
- locations by hand.
- <br>
- (Matthias Maier, 2015/04/08)
- </li>
-
- <li> Fixed: There were a number of places in the library where we unconditionally
- called functions <code>_mm_malloc()/_mm_free()</code> to allocate and free
- memory with a known alignment. This function, however, is only available on
- systems with x86 or x64_64 compatible processors. These places have now been
- replaced by calling <code>posix_memalign()</code> instead, a function that
- should be more widely available.
- <br>
- (Wolfgang Bangerth, 2015/04/15)
- </li>
-
- <li> Deprecated: The library uses functions such as CellAccessor::subdomain_id(),
- TriaAccessor::manifold_id(), etc, but used the deviant spelling
- TriaAccessor::boundary_indicator(), TriaAccessor::set_boundary_indicator(),
- TriaAccessor::set_all_boundary_indicators(). These last three functions are now
- deprecated and have been replaced by TriaAccessor::boundary_id(),
- TriaAccessor::set_boundary_id(), and TriaAccessor::set_all_boundary_ids() for
- consistency. Similar, Triangulation::get_boundary_indicators() has been
- deprecated in favor of Triangulation::get_boundary_ids().
- <br>
- (Wolfgang Bangerth, 2015/04/11)
- </li>
-
- <li> Changed: All example programs used to have calls to set_boundary()
- methods to deal with curved boundaries. These have been replaced with
- the corresponding set_manifold() equivalent.
- <br>
- (Luca Heltai, 2015/04/06)
- </li>
-
- <li> New: A new flag no_automatic_repartitioning in
- parallel::distributed::Triangulation will disable the automatic
- repartitioning when calling execute_coarsening_and_refinement() (or things
- like refine_global(), ...), resulting in all cells staying on the processor
- they were before. The new function repartition() will execute the
- repartitioning as done automatically before.
- <br>
- (Timo Heister, 2015/03/22)
- </li>
-
- <li> Changed: All (Block)Compressed*SparsityPattern classes got
- replaced by DynamicSparsityPattern and
- BlockDynamicSparsityPattern, respectively and all examples now
- teach the dynamic way of creating dynamic sparsity patterns.
- <br>
- (Timo Heister, 2015/03/22)
- </li>
-
- <li> Improved: We have traditionally had a large number of exceptions
- that did not output any useful error message other than the name
- of the exception class. This name was suggestive of the error that
- had happened, but did not convey a sufficient amount of information
- to what happened in many of the places where these kinds of exceptions
- were used, nor what may have caused the exception, or how it could
- be avoided. We have gone through many of these places and changed
- the exception to be much more verbose in what they state about the
- problem, its origin, and how it may be solved.
- <br>
- (Wolfgang Bangerth, 2015/02/28-2015/03/31)
- </li>
-
- <li> Changed: We have traditionally used Point@<dim@> to represent points
- in physical space, i.e., vectors that are anchored at the origin, whereas
- for vectors anchored elsewhere (e.g., differences between points, normal
- vectors, gradients, etc) we have used Tensor@<1,dim@>. This has now be
- made more formal in the documentation but also in the return types of
- <code>operator-()</code> for Point objects: The difference between two
- points, <code>p1-p2</code> now returns a Tensor@<1,dim@>. On the other
- hand, subtracting a Tensor@<1,dim@> object from a Point, <code>p-t</code>,
- results in a Point@<dim@>.
- <br>
- (Wolfgang Bangerth, 2015/02/05)
- </li>
-
- <li> New: Examples from 1 to 16 now use the Manifold interface
- instead of the old Boundary interface to describe curved boundaries
- and domains.
- <br>
- (Luca Heltai, 2015/01/15)
- </li>
-
- <li> New: The build system now queries for git branch name and
- revision sha1 (and automatically reconfigures if necessary). This
- information is used to annotate summary.log and detailed.log with the
- current revision sha1. Further, a header file <deal.II/base/revision.h>
- is now available that exports the macros: DEAL_II_GIT_BRANCH,
- DEAL_II_GIT_REVISION, DEAL_II_GIT_REVISION_SHORT.
- <br>
- (Matthias Maier, 2015/01/02)
- </li>
</ol>

-
- <li> New: Utilities::trim() function removes trailing and leading spaces.
- <br>
- (Timo Heister, 2015/07/11)
- </li>
-
- <li>Changed: The IsBlockMatrix class is now declared in

- </li>
-
- <li>Improved: GridOut::write_vtk() and GridOut::write_vtu() now
- output material id, level and subdomain ids of the cells.
- <br>
- (Guido Kanschat, 2015/07/05)
- </li>
-
- <li>Improved: The font scaling in GridOut::write_svg() was broken,
- since the units were missing. It has been fixed and an additional
- parameter GridOutFlags::Svg::cell_font_scaling has been introduced
- for tuning.
- <br>
- (Guido Kanschat, 2015/07/04)
- </li>
-
- <li> New: VectorizedArray now provides two methods
- vectorized_load_and_transpose() and vectorized_transpose_and_store() that
- perform vectorized reads or writes and convert from array-of-struct into
- struct-of-array or the other way around.
- <br>
- (Martin Kronbichler, 2015/07/02)
- </li>
-
- <li>New: GridGenerator::cheese() for a mesh with many holes;
- GridGenerator::simplex() for simplices in 2 and 3 dimensions;
- GridGenerator::hyper_cross() for crosses in 2 and 3 dimensions.
- <br>
- (Guido Kanschat, 2015/07/02)
- </li>
-
- <li> Fixed: The specialization of DoFAccessor for zero-dimensional objects,
- i.e., for vertices as created by accessing the faces of one-dimensional
- cells, had a member function DoFAccessor::child() that was declared but not
- implemented. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2015/07/01)
- </li>
-
- <li> Improved: Functions::Monomial::gradient function now works when both base and exponent
- are equal to zero for one or more components of the monomial.
- Also, an assertion is added to avoid exponentiation of negative base numbers with real exponents.
- <br>
- (Angel Rodriguez, 2015/06/29)
- </li>
-
- <li> Fixed: The function numbers::is_finite() produced incorrect results when
- called with a NaN number (specifically, it produces an uncatchable floating
- point exception when called with a signaling NaN). This was clearly not
- intended since such values are definitely not finite.
- <br>
- (Wolfgang Bangerth, 2015/06/29)
- </li>
-
- <li> Improved: The SparseMatrix class can now also use <code>std::complex</code>
- scalars for its elements.
- <br>
- (Wolfgang Bangerth, 2015/06/26)
- </li>
-
- <li> Improved: FE_DGQArbitraryNodes::get_name() now also detects if
- the quadrature rule was Gauss points.
- <br>
- (Guido Kanschat, 2015/06/22)
- </li>
-
- <li> Improved: DoFRenumbering::Cuthill_McKee() can now also
- use starting indices for parallel triangulations.
- <br>
- (Wolfgang Bangerth, 2015/06/11)
- </li>
-
- <li> Improved: VectorTools::interpolate now works with FE_Nothing.

- (David Wells, 2015/04/13)
- </li>
-
- <li> New: Add a clear function to the PETSc::Vector
- and PETSc::MPI::Vector classes similar to the Trilinos vector classes.
- <br>
- (Martin Steigemann 2015/05/22)
- </li>
-
- <li> New: Three new quadrature formulas in quadrature_lib, based on
- Chebyshev quadrature rules. See functions QGaussChebyshev,
- QGaussRadauChebyshev and QGaussLobattoChebyshev.
- <br>
- (Giuseppe Pitton, Luca Heltai 2015/05/11)
- </li>
-
- <li> Fixed: MatrixOut now also works with Trilinos and PETSc matrices.
- <br>
- (Wolfgang Bangerth, 2015/05/11)
- </li>
-
- <li> Changed: TrilinosWrappers::Vector, TrilinosWrappers::BlockVector,
- PETScWrappers::Vector, and PETScWrappers::BlockVector are deprecated. Either
- use the MPI or the deal.II version of the Vector/BlockVector.
- <br>
- (Bruno Turcksin, 2015/05/04)
- </li>
-
- <li> Fixed: GridGenerator::half_hyper_shell can now be colorized.
- <br>
- (Daniel Arndt, 2015/05/05)
- </li>
-
- <li> New: The function VectorTools::point_gradient has been added to compute
- the gradient of a given FE function.

-
- <li> New: dealii:Vector, dealii::BlockVector,
- TrilinosWrappers::MPI::Vector, TrilinosWrappers::MPI::BlockVector,
- PETScWrappers::MPI::Vector and PETScWrappers::MPI::BlockVector now have
- move constructors and move assignment operators in C++11 mode.

- (Ian Rose, 2015/04/24)
- </li>
-
- <li> Fixed: project_boundary_values_curl_conforming_l2() produced incorrect

- computed fixes this.
- <br>
- (Ross Kynch, 2015/04/23)
- </li>

- (Lei Qiao, 2015/04/19)
- </li>
-
- <li> New: The VectorTools::integrate_difference() function can now
- also compute the $H_\text{div}$ seminorm, using the

- one and two Triangulation;

- (Luca Heltai, 2015/04/12)
- </li>
-
- <li> New: A new VectorTools::get_position_vector() function has been
- added to the library that allows one to interpolate the Geometry of
- a (possibly curved) triangulation to vector finite element fields
- of at least spacedim components.
- <br>
- (Luca Heltai, 2015/04/11)

- (Matthias Maier, 2015/04/08)
- </li>
-
- <li> New: A new MappingFEField() class has been added to the library
- that generalizes MappingQEulerian to allow arbitrary FiniteElements.
- <br>
- (Marco Tezzele, Luca Heltai, 2015/04/06)
- </li>
-
- <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.
- <br>
- (Martin Kronbichler, 2015/04/10)
- </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.
- <br>
- (Martin Kronbichler, 2015/04/10)
- </li>
-
- <li> New: One can now ask a cell the how many-th active cell it is,
- using CellAccessor::active_cell_index() (which is called as
- <code>cell-@>active_cell_index()</code>).
- <br>
- (Wolfgang Bangerth, 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.
- <br>
- (Denis Davydov, 2015/04/10)
- </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> 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> 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> New: Added FE_Bernstein: a scalar finite element based on Bernstein basis polynomials.
- <br>
- (Marco Tezzele, Luca Heltai, 2015/03/31)
- </li>
-
- <li> New: A function to get a map with all vertices at boundaries has
- been added at GridTools::get_all_vertices_at_boundary(). This function
- will return a map which can be used in functions like
- GridTools::laplace_transform().
- <br>
- (Fernando Posada, 2015/03/31)
- </li>
-
- <li> Fixed: TrilinosWrappers::SparseMatrix::local_range() erroneously
- threw an exception in 64-bit mode. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2015/03/24)
- </li>
-
- <li> New: The GridOut::write_gnuplot() function produced output
- for 1d meshes embedded in higher dimensional spaces that was
- invalid in that the lines showing individual cells were connected.
- While this is not wrong for singly connected 1d meshes, it leads to wrong
- results if the domain is not singly connected and not every cell is the
- right neighbor of the previous cell.
- <br>
- (Wolfgang Bangerth, 2015/03/23)
- </li>
-
- <li> New: The various file format writers of class GridOut were not
- instantiated for 1d meshes in 3d space. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2015/03/23)
- </li>
-
- <li> New: ParameterHandler::declare_alias() allows to define
- alternate names for parameters. This is primarily intended to allow
- for backward compatible ways of changing the names of parameters
- to applications.
- <br>
- (Wolfgang Bangerth, 2015/03/22)
- </li>
-
- <li> New: GridGenerator::create_triangulation_with_removed_cells() creates
- a new mesh out of an existing one by dropping individual cells.
- <br>
- (Wolfgang Bangerth, 2015/03/13)
- </li>
-
- <li> New: Add MueLu preconditioner from Trilinos through the class
- TrilinosWrappers::PreconditionAMGMueLu. This is a new algebraic
- multigrid package. The input parameters are almost the same as the ones
- from ML so that the two preconditioners can be easily swapped.
- <br>
- (Bruno Turcksin, 2015/03/11)
- </li>
-
- <li> Fixed: Iterating over the elements of a TrilinosWrappers::SparseMatrix
- object previously led to errors if the matrix was in fact stored in
- parallel across multiple MPI processes. This is now fixed: rows not
- stored locally on the processor where you run the iteration simply look
- like they're empty.
- <br>
- (Wolfgang Bangerth, 2015/03/08)
- </li>
-
- <li> New: There is now a new macro DeclExceptionMsg that allows to
- declare an exception that does not take any run-time arguments
- yet still allows to specify an error message.
- <br>
- (Wolfgang Bangerth, 2015/02/27)
- </li>
-
- <li> New: There is now a class std_cxx11::unique_ptr that provides
- the functionality of std::unique_ptr in C++11 mode, and that
- provides an emulation for older compilers.
- <br>
- (Wolfgang Bangerth, 2015/02/22)
- </li>
-
- <li> New: IndexSet now has a local typedef IndexSet::value_type.
- <br>
- (Wolfgang Bangerth, 2015/02/22)
- </li>
-
- <li> New: FE_TraceQ can now also be used in 1D.
- <br>
- (Martin Kronbichler, 2015/02/21)
- </li>
-
- <li> New: FE_TraceQ now implements get_face_interpolation_matrix and
- get_subface_interpolation_matrix, enabling
- DoFTools::make_hanging_node_constraints on this element.
- <br>
- (Anton Evgrafov, 2015/02/21)
- </li>
-
- <li> Fixed: MappingQEulerian would previously not move interior points
- in 1D for higher order mappings. This has been fixed by removing a few
- specializations of MappingQ for 1D that are no longer necessary.
- <br>
- (Martin Kronbichler, 2015/02/19)
- </li>
-
- <li> Fixed: The implementation of the class GrowingVectorMemory has been
- moved from source/lac/vector_memory.cc to the new file
- include/deal.II/lac/vector_memory.templates.h. This allows users to
- create instantiations of GrowingVectorMemory for their own vector classes
- in case they intend to use them for the deal.II solvers.
- <br>
- (Martin Kronbichler, 2015/02/18)
- </li>
-
- <li> Changed: All members of MultithreadInfo are now static so it is no
- longer necessary to use the global instance multithread_info (now
- deprecated) or create your own instance (which does not work correctly
- anyway).
- <br>
- (Timo Heister, 2015/02/13)
- </li>
-
- <li> Fixed: There was a bug in the energy source term of step-33 whereby
- the term was erroneously multiplied by the density. This is now fixed.
- <br>
- (Praveen C, Lei Qiao, 2015/02/13)
- </li>
-
- <li> Changed: If you take the product of a Tensor and a scalar number,
- you previously got a Tensor back that stored its elements in the same
- data type as the original tensor. This leads to problems if you
- multiply a <code>Tensor@<1,dim,double@></code> by a
- <code>std::complex@<double@></code> because the result clearly needs
- to store its elements as complex numbers, rather than as double
- variables. This is now changed: The result of the product of a Tensor
- and a scalar number is now a Tensor that stores its elements in a data
- type appropriate for this product. The same approach is taken for the
- SymmetricTensor class.
- <br>
- (Wolfgang Bangerth, 2015/02/11)
- </li>
-
- <li> New: There is now a new class ProductType that can be used
- to infer the type of the product of two objects. There is now also
- a class EnableIfScalar that helps restrict some templates to only
- cases where a type is a scalar.
- <br>
- (Wolfgang Bangerth, 2015/02/04)
- </li>
-
- <li> New: The Tensor classes now have copy constructors and copy
- operators that allow assignment from other tensors with different
- underlying scalar types.
- <br>
- (Denis Davydov, 2015/02/03)
- </li>
-
- <li> New: Class hp::DoFHandler can now also be serialized.
- <br>
- (Lukas Korous, 2015/01/31)
- </li>
-
- <li> Bugfix: deal.II now correctly links against librt in case of bundled
- boost being used.
- <br>
- (Matthias Maier, 2015/01/27)
- </li>
-
- <li> New: A new macro <code>DEAL_II_QUERY_GIT_INFORMATION</code> is
- provided to query user projects for git repository information simmilarly
- to those exported by deal.II.
- <br>
- (Matthias Maier, 2015/01/21)
- </li>
-
- <li> Fixed: FEFaceValues and FESubfaceValues did not fill the
- jacobians and inverse jacobians if requested via the update flags.
- This is now fixed.
- <br>
- (Martin Kronbichler, 2015/01/23)
- </li>
-
- <li> Fixed: ParameterHandler::read_input() now checks that
- 'subsection'/'end' are balanced in the input.
- <br>
- (Timo Heister, 2015/01/19)
- </li>
-
- <li> Fixed: In 3d, when you set the <code>colorize</code> flag of
- GridGenerator::hyper_shell(), the faces of the domain were colored but
- the edges were not. This was an oversight because to refine correctly,
- the edges also have to have the appropriate boundary indicator set.
- <br>
- (Wolfgang Bangerth, 2015/01/16)
- </li>
-
- <li> New: dealii::multithread_info.n_cpus returns the correct number of CPU
- on FreeBSD.
- <br>
- (Bruno Turcksin, 2015/01/14)
- </li>
-
- <li> Improved: MPI collective operations such as MPI::sum, MPI::max now
- check for job_supports_mpi() internally, which allows running them also
- without a call to MPI_Init.
- <br>
- (Martin Kronbichler, 2015/01/13)
- </li>
-
- <li> Changed: The method job_supports_mpi() now resides in the namespace
- Utilities::MPI instead of Utilities::System for consistency with other MPI
- methods. The old method has been marked deprecated and will be removed in
- a future version.
- <br>
- (Martin Kronbichler, 2015/01/13)
- </li>
-
- <li> Fixed: The update of ghost values in parallel::distributed::Vector when
- calling the assignment operator is now active when one of the two vector had
- its ghost values updated before or when the layout of the right hand side
- vector is one-to-one, more consistent with parallel PETSc and Trilinos
- vectors.
- <br>
- (Martin Kronbichler, 2015/01/13)
- </li>
-
- <li> New: PETScWrappers::MPI::SparseMatrix::reinit(other) copies
- the layout of another matrix. TrilinosWrappers::SparseMatrix
- operator= and copy constructor are now disabled. This brings
- functionality between PETSc and Trilinos in line.
- <br>
- (Timo Heister, 2015/01/12)
- </li>
-
- <li> New: Triangulation::set_all_manifold_ids() and
- Triangulation::set_all_manifold_ids_on_boundaries()
- set all manifold ids on every object or on every
- boundary object respectively.
- <br>
- (Luca Heltai, 2015/01/12)
- </li>
-
- <li> New: GridTools::copy_boundary_to_manifold_id() and
- GridTools::copy_material_to_manifold_id() copy
- boundary_ids and material_ids to manifold_ids for
- faces on the boundary and for cells respectively.
- <br>
- (Luca Heltai, 2015/01/09)
- </li>
-
- <li> Fixed: Utilities::int_to_string() produced wrong results if
- the number of digits specified was ten or greater.
- <br>
- (David Wells, 2015/01/08)
- </li>
-
- <li> Fixed: VectorTools::interpolate_to_different_mesh() was accidentally
- only instantiated for dealii::Vector arguments, rather than all vector
- classes. This is now fixed.
- <br>
- (Benjamin Brands, Wolfgang Bangerth, 2014/12/29)
- </li>
-
- <li> Fixed: Use CASROOT environment variable as additional hint for
- opencasacade.
- <br>
- (Matthias Maier, 2014/12/29)
- </li>
-
- <li> Fixed: Update the run_testsuite.cmake script to also pick up
- muparser and opencascade configuration.
- <br>
- (Matthias Maier, 2014/12/29)
- </li>
- <li> Fixed: Update several places in the documentation that were not
- updated from functionparser to muparser. Add several forgotten
- DEAL_II_WITH_* variables to certain places in the documentation.
- <br>
- (Matthias Maier, 2014/12/29)
