-Version 4.2.1 (development)
+Version 4.1.1 (development)
 ===========================

- Added high-order matrix-free auxiliary Maxwell solver for H(curl) problems,
-  as described in Barker and Kolev 2020 (https://doi.org/10.1002/nla.2348). See
-  Example 3p and linalg/auxiliary.?pp.
-
- Added a new miniapp block-solvers that compares the performance of various
-  solvers for mixed finite element discretization of the second order scalar
-  elliptic equations. Currently available solvers in the miniapp include a
-  block-diagonal preconditioner that is based on approximate Schur complement
-  (implemented in ex5p), and a newly implemented solver DivFreeSolver, which
-  exploits a multilevel decomposition of the Raviart-Thomas space and its
-  divergence-free subspace. See the miniapps/solvers directory for more details.
-
- Added a new miniapp for computing (signed) distance functions to a point
-  source or zero level set. See miniapps/shifted/distance.cpp.
-
- Added matrix-free GPU-enabled implementations of GradientInterpolator and
-  IdentityInterpolator.
-
- Added interface to MUMPS direct solver. Its usage is demonstrated in ex25p.
-  See http://mumps.enseeiht.fr/ for more details. Supported versions >= 5.1.1.
-
- Added three ESDIRK time integrators: implicit trapezoid rule, L-stable
-  ESDIRK-32, and A-stable ESDIRK-33.
-
- Introduced a new non-conforming mesh format that fixes known inconsistencies
-  of legacy "MFEM mesh v1.1" NC format and works consistently in both serial and
-  parallel. ParMesh::ParPrint can now print non-conforming AMR meshes that can
-  be used to restart a parallel AMR computation. Example 6p has been extended to
-  demonstrate restarting from a previously saved checkpoint. Note that parallel
-  NC data files are compatible with serial code, e.g., can be viewed with serial
-  GLVis. Loading of legacy NC mesh files is still supported.
-
- Added a "scaled Jacobian" visualization option in the Mesh Explorer miniapp to
-  help identify elements with poor mesh quality.
-
- Added support for the "BR2" discontinuous Galerkin discretization for
-  diffusion via DGDiffusionBR2Integrator (see Example 14/14p).
-
- Generalized the Multigrid class to support non-geometric multigrid. The
-  previous functionality, based on FiniteElementSpaceHierarchy, is now available
-  in the derived class GeometricMultigrid.
-
- Upgraded the Catch unit test framework from version 2.13.0 to version 2.13.2.
-
- Implemented a filter method for the Navier miniapp to stabilize highly
-  turbulent flows in direct numerical simulation.
-
- Added HIP support to the CMake build system.
-
- Added support for reading high-order Lagrange meshes in VTK format. Arbitrary-
-  orders and all element types are supported. See the VTK blog for more info:
-  https://blog.kitware.com/wp-content/uploads/2018/09/Source_Issue_43.pdf.
-
- Added support for reading VTK meshes in XML format.
-
- Added partial assembly and device support to Example 25/25p, with diagonal
-  preconditioning.
-
- Implemented a variable step-size IMEX (VSSIMEX) method for the Navier miniapp.
-
- Added new mesh quality metrics and improved the untangling capabilities of the
-  TMOP-based mesh optimization algorithms.
-
- Added convective and skew-symmetric integrators for the nonlinear term in the
-  Navier-Stokes equations.
-
- Changed the interface for the error estimator.
-
- Implemented the parallel Kelly error indicator for scalar-valued problems.
-
- Added new classes DenseSymmetricMatrix and SymmetricMatrixCoefficient for
-  efficient evaluation of symmetric matrix coefficients. This replaces the now
-  deprecated EvalSymmetric in MatrixCoefficient. Added DiagonalMatrixCoefficient
-  for clarity, which is a typedef of VectorCoefficient.
-
- Added support for AMG preconditioners for non-symmetric systems (e.g.
-  advection-dominated problems) using hypre's approximate ideal restriction
-  (AIR) AMG. Requires hypre version 2.14.0 or newer. Usage is illustrated in
-  example 9/9p.
-
- Implemented an adaptive linear solver tolerance option for NewtonSolver based
-  on the algorithm of Eisenstat and Walker.
-
- Added support for nonscalar coefficient with VectorDiffusionIntegrator.
-
- Extending support for L2 basis functions using MapTypes VALUE and INTEGRAL in
-  linear interpolators and GridFunction "GetValue" methods.
-
- Variable order spaces, p- and hp-refinement. This is the initial (serial)
-  support for variable-order FiniteElementCollection and FiniteElementSpace.
-  The new method FiniteElementSpace::SetElementOrder can be called to set an
-  arbitrary order for each mesh element. The conforming interpolation matrix
-  will now automatically constrain p- and hp- interfaces, enabling general
-  hp-refinement in both 2D and 3D, on uniform or mixed NC meshes. Support for
-  parallel variable-order spaces will follow shortly.
-
- Added support for creating refined meshes for all element types (e.g. by
-  splitting high-order elements into low-order refined elements), including
-  mixed meshes. The LOR Transfer miniapp (miniapps/tools/lor-transfer.cpp) now
-  supports meshes with any element geometry.
-
- Gitlab CI: use Spack (and Uberenv) to automate the build of TPLs.
-
-libCEED integration improvements
--------------------------------
- Refactor the libCEED integration
-
- Add support for VectorCoefficient with libCEED backends.
-
- Add support for ConvectionIntegrator, and VectorConvectionNLFIntegrator with libCEED backends.
-
-
-Version 4.2, released on October 30, 2020
-=========================================
-
-High-Performance Computing
--------------------------
- Added support for explicit vectorization in the high-performance templated
-  code, which can now take advantage of specific classes on the following
-  architectures:
-  * x86 (SSE/AVX/AVX2/AVX512),
-  * Power8 & Power9 (VSX),
-  * BG/Q (QPX).
-  These are disabled by default, but can be enabled with MFEM_USE_SIMD=YES.
-  See the new file linalg/simd.hpp and the new directory linalg/simd.
-
- Added an Element Assembly mode compatible with GPU device execution for H1 and
-  L2 spaces in the mass, convection, diffusion, transpose, and the face DG trace
-  integrators. See option '-ea' in Example 9. When enabled, this assembly level
-  stores independent dense matrices for the elements, and independent dense
-  matrices for the faces in the DG case.
-
- Added a Full Assembly mode compatible with GPU device execution. This assembly
-  level builds on top of the Element Assembly kernels to compute a global sparse
-  matrix. All integrators supported by element assembly are also supported by
-  full assembly. See the '-fa' option in Example 9.
-
- Optimized the AMD/HIP kernel support and enabled HIP support in the libCEED
-  integration. This is now available via the "ceed-hip" device backend.
-
- Improved the libCEED integration to support:
-  * AssemblyLevel::NONE for Mass, Diffusion, VectorMass, and VectorDiffusion
-    Integrators. This level computes the full operator evaluation "on the fly".
-  * VectorMassIntegrator and VectorDiffusionIntegrator.
-  * All types of (scalar) Coefficients.
-
- Added partial assembly / device support for:
-  * H(div) bilinear forms and VectorFEDivergenceIntegrator.
-  * BlockOperator, see the updated Example 5.
-  * Complex operators, see the updated Example 22.
-  * Chebyshev accelerated polynomial smoother.
-  * Convergent diagonal preconditioning on non-conforming adaptively refined
-    meshes, see Example 6/6p.
-
- Added CUDA support for:
-  * Sparse matrix-vector multiplication with cuSPARSE,
-  * SUNDIALS ODE integrators, see updated SUNDIALS modification of Example 9/9p.
-
-Linear and nonlinear solvers
----------------------------
- Added a new solver class for simple integration with NVIDIA's multigrid
-  library, AmgX. The AmgX class is designed to work as a standalone solver or
-  preconditioner for existing MFEM solvers. It uses MFEM's sparse matrix format
-  for serial runs and the HypreParMatrix format for parallel runs. The new
-  solver may be configured to run with one GPU per MPI rank or with more MPI
-  ranks than GPUs. In the latter case, matrices and vectors are consolidated to
-  ranks communicating with the GPUs and the solution is then broadcasted.
-
-  Although CUDA is required to build, the AmgX support is compatible with the
-  MFEM CPU device configuration. The examples/amgx folder illustrates how to
-  integrate AmgX in existing MFEM applications. The AmgX solver class is
-  partially based on: "AmgXWrapper: An interface between PETSc and the NVIDIA
-  AmgX library", by Pi-Yueh Chuang and Lorena A. Barba, doi:10.21105/joss.00280.
-
- Added initial support for geometric h- and p-multigrid preconditioners for
-  matrix-based and matrix-free discretizations with basic GPU capability, see
-  Example 26/26p.
-
- Added support for the CVODES package in SUNDIALS which provides ODE solvers
-  with sensitivity analysis capabilities. See the CVODESSolver class and the new
-  adjoint miniapps in the miniapps/adjoint directory.
-
- Added an interface to the MKL CPardiso solver, an MPI-parallel sparse direct
-  solver developed by Intel. See Example 11p for an illustration of its usage.
-
- Added support for the SLEPc eigensolver package, https://slepc.upv.es.
-
- Upgraded SuperLU interface to use SuperLU_DIST 6.3.1. Added a simple SuperLU
-  example in the new directory examples/superlu.
-
- Extended the KINSOL (SUNDIALS) nonlinear solver interface to support the
-  Jacobian-free Newton-Krylov method. A usage example is shown in Example 10p.
-
- Block arrays of parallel matrices can now be merged into a single parallel
-  matrix with the function HypreParMatrixFromBlocks. This could be useful for
-  solving block systems with parallel direct solvers such as STRUMPACK.
-
- Added wrappers for hypre's flexible GMRES solver and the new parallel ILU
-  preconditioner. The latter requires hypre version 2.19.0 or later.
-
-Discretization improvements
---------------------------
- Extended GSLIB-FindPoints integration to support simplices and interpolation
-  of functions from L2, H(div) and H(curl) spaces.
-
- Added support for computing asymptotic error estimates and convergence rates
-  for the whole de Rham sequence based on the new class ConvergenceStudy and new
-  member methods in GridFunction and ParGridFunction. See the rates.cpp file in
-  the tests/convergence directory for sample usage.
-
- Extended the GetValue and GetVectorValue methods of GridFunction to support
-  evaluation on boundary elements and, in the continuous field case, arbitrary
-  mesh edges and faces. This requires passing an ElementTransformation argument.
-
- Added support for matrix-free interpolation and restriction operators between
-  continuous H1 finite element spaces of different order on the same mesh or
-  with the same order on uniformly refined meshes.
-
- The Coefficient classes based on a C-function pointer (FunctionCoefficient,
-  VectorFunctionCoefficient and MatrixFunctionCoefficient) now use the more
-  general std::function class template. This allows the classes to be backward
-  compatible (i.e. they can still work with C-functions) and, in addition,
-  support any "callable", e.g. lambda functions.
-
- Non-conforming meshes are now supported with block nonlinear forms. See the
-  updated Example 19/19p.
-
 Meshing improvements
 --------------------
 - The graph linear ordering library Gecko, previously an external dependency, is
  now included directly in MFEM. As a result, Mesh::GetGeckoElementOrdering is
  always available. The interface has also been improved, see for example the
-  Mesh Explorer miniapp.
+  mesh-explorer miniapp.

 - Added support for finite difference-based gradient and Hessian approximation
  in the TMOP mesh optimization algorithms. This improves the accuracy of the
  Hessian for r-adaptivity using discrete fields, and allows use of skewness
  and orientation based metrics.

- Improved Gmsh reader (version 2.2), which now supports both high-order and
-  periodic meshes. Segments, triangles, quadrilaterals, and tetrahedra are
-  supported up to order 10. Wedges and hexahedra are supported up to order 9.
-  For sample periodic meshes, see the periodic*.msh files in the data directory.
+Improved GPU capabilities
+-------------------------
+- Added support for Chebyshev accelerated polynomial smoother on GPU.

- Added support for construction of (serial) non-conforming meshes. Hanging
-  nodes can be marked with Mesh::AddVertexParents when building the mesh with
-  the "init" constructor. The usage is demonstrated in a new meshing miniapp,
-  Polar NC, which generates meshes that are non-conforming from the start.
+Discretization improvements
+---------------------------
+- Added support for matrix-free interpolation and restriction operators between
+  continuous H1 finite element spaces of different order on the same mesh or
+  with the same order on uniformly refined meshes.

- Added support for r-adaptivity with more than one discrete field. This allows
-  the user to specify different discrete functions for controlling the size,
-  aspect-ratio, orientation, and skew of elements in the mesh.
+- Added support for simplices in GSLIB-FindPoints.

- Additional TMOP improvements:
-  * Capability for approximate tangential mesh relaxation.
-  * Support and examples for using TMOP on mixed meshes.
-  * Complete integrator action accounting for spatial derivatives of discrete
-    and analytic targets.
+Linear and nonlinear solvers
+----------------------------
+- Added power method to iteratively estimate the largest eigenvalue and the
+  corresponding eigenvector of an operator.
+
+- Added initial support for h- and p-multigrid solvers and preconditioners for
+  matrix-based and matrix-free discretizations with basic GPU capability.

 New and updated examples and miniapps
 -------------------------------------
- Added a new miniapp, Navier, that solves the time-dependent Navier-Stokes
-  equations of incompressible fluid dynamics. See the miniapps/navier directory
-  for more details.
+- Added a new example, Example 25/25p, to demonstrate the use of a Perfectly
+  Matched Layer (PML) for the simulation of electromagnetic wave propagation.
+  The example defines and solves several indefinite Maxwell problems.

- Added 10 new example codes:
-  * Example 25/25p demonstrates the use of a Perfectly Matched Layer (PML) for
-    electromagnetic wave propagation (indefinite Maxwell).
-  * Example 26/26p shows how to construct matrix-free geometric and p-multigrid
-    preconditioner for the Laplace problem.
-  * Example 27/27p demonstrates the enforcement of Dirichlet, Neumann, Robin,
-    and periodic boundary conditions with either H1 or DG Laplace problems.
-  * Versions of Example 1/1p in examples/amgx demonstrating the use of AmgX,
-    to solve the Laplace problem with AMG preconditioning on GPUs.
-  * A version of Example 11p in examples/petsc demonstrating the use of SLEPc,
-    to solve the Laplace eigenproblem with shift-and-invert transformation.
-  * A version of Example 1 in examples/superlu demonstrating the use of SuperLU
-    to solve the Laplace problem.
+- Added a new Example 26/26p to demonstrate the construction of a matrix-free
+  geometric and p-multigrid preconditioner for the Laplace problem.

- Added a new Field Interpolation miniapp in miniapps/gslib that demonstrates
-  transfer of grid functions between different meshes using GSLIB-FindPoints.
+- Added a new example, Example 27/27p, to demonstrate the enforcement of
+  various boundary conditions with the Laplace operator.  The example shows the
+  procedures for applying Dirichlet, Neumann (both homogeneous and
+  inhomogeneous), Robin, and periodic boundary conditions with either H1 or DG
+  discretizations.

- Added 2 miniapps in the new miniapps/adjoint directory demonstrating how to
-  solve adjoint problems in MFEM using the CVODES package in SUNDIALS. Both of
-  these miniapps require the MFEM_USE_SUNDIALS configuration option.
-  * The cvsRoberts_ASAi_dns miniapp solves a backward adjoint problem for a
-    system of ODEs, evaluating both forward and adjoint quadratures in serial.
-  * The adjoint_advection_diffusion miniapp solves a backward adjoint problem
-    for an advection diffusion PDE, evaluating adjoint quadratures in parallel.
+- Added a simple meshing miniapp, Twist, which demonstrates MFEM's strategy of
+  stitching together opposite surfaces of a mesh to create a topologically
+  periodic mesh.

- Added 4 additional meshing miniapps:
-  * The Minimal Surface miniapp solves Plateau's problem: the Dirichlet problem
-    for the minimal surface equation.
-  * The Twist miniapp demonstrates how to stitch together opposite surfaces of a
-    mesh to create a topologically periodic mesh.
-  * The Trimmer miniapp trims away parts of a mesh based on element attributes.
-  * Polar NC shows the construction of polar non-conforming meshes.
-
- Several examples and miniapps were updated to include:
-  * Full and element assembly support in Example 9/9p.
-  * Partial assembly with diagonal preconditioning in Examples 4/4p/5/5p/22/22p.
-  * Diagonal preconditioner in Example 6/6p for partial assembly with AMR.
-  * The option to plot a function in Mesh Explorer.
-  * A new test problem showing a mixed bilinear form for H1, H(curl), H(div) and
-    L2, with partial assembly support in Example 24/24p.
-  * Weak Dirichlet boundary conditions (Nitsche) to the NURBS miniapp.
-
-Data management and Visualization
---------------------------------
- Added support for ADIOS2 for parallel I/O with ParaView visualization. See
-  Examples 5, 9, 12, 16. The classes adios2stream and ADIOS2DataCollection
-  provide the interface to generate ADIOS2 Binary Pack (BP4) directory datasets.
-
- Added VTU output of boundary elements and attributes and parallel VTU (PVTU)
-  output of parallel meshes for visualization using ParaView.
