-# General GitLab pipelines configurations for supercomputers and Linux clusters
-# at Lawrence Livermore National Laboratory (LLNL). This entire pipeline is
-# LLNL-specific!
-
-# We define the following GitLab pipeline variables:
-#
-# BUILD_ROOT:
-# The path to the shared resources between all jobs. For example, external
-# repositories like 'tests' and 'tpls' are cloned here. Also, 'tpls' is built
-# once for all targets, so that build happen here. The BUILD_ROOT is unique to
-# the pipeline, preventing any form of concurrency with other pipelines. This
-# also means that the BUILD_ROOT directory will never be cleaned.
-# TODO: add a clean-up mechanism
-#
-# BUILD_PATH:
-# In BUILD_ROOT, we want to separate builds depending on the machine used,
-# typically because we build on a set of dependencies per machine.
-#
-# REBASELINE:
-# Defines the default choice for updating the saved baseline results. By default
-# the baseline can only be updated from the master branch. This variable offers
-# the option to manually ask for rebaselining from another branch if necessary.
-#
-# MFEM_ALLOC_NAME:
-# On LLNL's quartz, there is only one allocation shared among jobs in order to
-# save time and resources. This allocation has to be uniquely named so that we
-# are sure to retrieve it.
-#
-# TPLS_REPO & TESTS_REPO:
-# Git repositories used in the pipeline
-#
-# ARTIFACTS_DIR:
-# Directory used to place artifacts.

-# The pipeline is divided into stages. Usually, these are also synchronization
-# points, however, we use "needs" keyword to express the DAG of jobs for more
-# efficiency.
-# - We use setup phase to download content outside of mfem directory.
-# - Allocate is where quartz resources are allocated once for all.
-# - Libs is where dependencies are built.
-# - Build is where we build MFEM for multiple toolchains.
-# - Test is where we perform a first set of tests on MFEM build.

-Version 4.1.1 (development)
-===========================
+Version 4.0-RC1, Apr 11, 2019
+=============================

-libCEED integration improvements
--------------------------------
- Add support for all types of (scalar) Coefficient.
-
- Add support for VectorMassIntegrator and VectorDiffusionIntegrator.
-
- Add support for AssemblyLevel::NONE for MassIntegrator, DiffusionIntegrator,
-  VectorMassIntegrator, and VectorDiffusionIntegrator. This level of assembly
-  fully applies on the fly the finite element operator.
-
-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.
-
- 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.
-
- 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.
-
- 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 TMOP capability for approximate tangential mesh relaxation. Added
-  support and examples for using TMOP on mixed meshes.
-
- Added complete action of the TMOP Integrator to account for the spatial
-  derivatives of discrete and analytic targets.
-
- Added support for initialization 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.
-
-Performance improvements
------------------------
- Added support for explicit vectorization in the high-performance templated
-  code, which can now take advantage of specific intrinsics classes on the
-  following architectures:
-    - x86 (SSE/AVX/AVX2/AVX512),
-    - Power8 & Power9 (VSX),
-    - BG/Q (QPX).
-  These are disabled by default, and can be enabled with MFEM_USE_SIMD=YES.
-  See the new file linalg/simd.hpp and the new directory linalg/simd.
-
-Improved GPU capabilities
-------------------------
- 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 support for Chebyshev accelerated polynomial smoother on GPU.
-
- Optimized AMD/HIP kernel support.
-
- Enabled HIP support in the libCEED integration, which is now available via the
-  "ceed-hip" device backend.
-
- Added a Full Assembly mode compatible with Device kernel execution. This
-  assembly level builds on top of the current 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.
-
- Added CUDA support for sparse matrix-vector multiplication with cuSPARSE.
-
- Added support for BlockOperator on GPU. See the updated Example 5.
-
- Added partial assembly and GPU support for complex operators, including the
-  classes ComplexOperator, [Par]ComplexGridFunction, [Par]ComplexLinearForm, and
-  [Par]SesquilinearForm. See the updated Example 22.
-
- Added CUDA support for SUNDIALS ODE integrators. See the updated SUNDIALS
-  modification of Example 9/9p.
-
-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 simplices in GSLIB-FindPoints.
-
- Added support for H1 and L2 element matrix assembly in the mass, convection,
-  diffusion, transpose, and the face DG trace integrators. This is compatible
-  with GPU device execution and is illustrated in Example 9/9p, see the option
-  '-ea'. When enabled, this level of assembly stores independent dense matrices
-  for the elements, and independent dense matrices for the faces in the DG case.
-
- Added new partial assembly kernels for H(div) bilinear forms, as well as
-  VectorFEDivergenceIntegrator.
-
- Improved the documentation of the GridFunction GetValue and GetVectorValue
-  methods. Expanded the GetValue and GetVectorValue methods which accept an
-  ElementTransformation argument to support evaluation on boundary elements
-  and, in the continuous field case, arbitrary mesh edges and faces.
-
- Added new coefficient and vector coefficient classes for QuadratureFunctions.
-  Additionally, new LinearForm integrators were also added which make use of
-  these new QuadratureFunction coefficient classes.
-
- Non-conforming meshes are now supported with block nonlinear forms. See the
-  updated Example 19/19p.
-
- Added support face integrals on the boundaries of NURBS meshes.
-
- Added support for interpolation of functions in L2, H(div) and H(curl)
-  spaces using GSLIB-FindPoints.
-
- 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.
-
- The C-function based coefficient classes (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.
-
-Linear and nonlinear solvers
+Requirements and Limitations
 ----------------------------
- 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.
-
- Added wrappers for Hypre's flexible GMRES solver and the new parallel ILU
-  preconditioner. The latter requires hypre version 2.19.0 or later.
-
- Added a new IterativeSolverMonitor class that allows to monitor the residual
-  and solution during the solving process of an IterativeSolver after every
-  iteration.
-
- 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 below.
-
- 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.
-
- In SLISolver, changed the residual inner product from (Br,r) to (Br,Br) so the
-  solver can work with non-SPD preconditioner B.
-
- Added support for the SLEPc eigensolver package.
-
- Added partially assembled convergent diagonal preconditioner for adaptively
-  refined meshes (i.e. non-conforming finite element spaces), see Example 6/6p.
-
- 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.
-
- 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.
-
-New and updated examples and miniapps
-------------------------------------
- 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 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 example, Example 27/27p, to demonstrate the enforcement of various
-  boundary conditions with the Laplace operator. The example shows the procedure
-  for applying Dirichlet, Neumann (both homogeneous and inhomogeneous), Robin,
-  and periodic boundary conditions with either H1 or DG discretizations.
-
- 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 miniapps/adjoint directory with two miniapps 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.
-
- Ported Example 11p to SLEPc, to demonstrate solving the Laplace eigenvalue
-  equation with the shift-and-invert spectral transformation method.
-
- 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 a new meshing miniapp, Minimal Surface, which solves Plateau's problem:
-  the Dirichlet problem for the minimal surface equation.
-
- Added a new meshing miniapp, Polar NC, which demonstrates the construction of
-  polar non-conforming meshes.
-
- Added partial assembly support to Example 4/4p and Example 5/5p, with diagonal
-  preconditioning.
-
- Added full assembly support in Example 9/9p.
-
- Added a new test problem in Example 24/24p, demonstrating a mixed bilinear
-  form for H1, H(curl), H(div) and L_2, with partial assembly support.
-
- Added weak Dirichlet boundary conditions (Nitsche) to the NURBS miniapp.
-
- Added a simple mesh editing miniapp, Trimmer, which trims away portions of a
-  mesh based on element attributes. Any newly exposed boundary elements are
-  assigned attribute numbers related to the trimmed element attributes.
-
- Added a new miniapp (field-interp) that demonstrates transfer of grid function
-  between different meshes using GSLIB-FindPoints.
-
- Added diagonal preconditioner in Example 6/6p for partial assembly with AMR.
-
- Added device support in Example 5/5p.
-
- Added partial assembly and device support to Example 22/22p, with diagonal
-  preconditioning.
-
- Added the option to plot a function in Mesh Explorer.
-
-Improved testing
----------------
- Upgraded the Catch unit test framework from version 1.6.1 to version 2.13.0.
-
- Added a GitLab pipeline that automates PR testing on supercomputing systems
-  and Linux clusters at Lawrence Livermore National Lab (LLNL). This can be
-  triggered only by LLNL developers, see .gitlab-ci.yml, the .gitlab directory
-  and the updated CONTRIBUTING.md file.
-
- Add tests for the libCEED integration in MFEM.
-
- Added testing of the parallel mesh format in tests/par-mesh-format.
-
-Miscellaneous
-------------
- Added support for ADIOS2 for parallel I/O with ParaView visualization. The
-  classes adios2stream and ADIOS2DataCollection are introduced in mfem as the
-  interfaces to generate ADIOS2 Binary Pack (BP4) directory datasets for the
-  entire spatial and temporal node data. Cell centered data is accessible by
-  ADIOS2 data readers (e.g. Python), but currently not yet implement as of
-  ParaView v5.8.1. In addition, ADIOS2 allows for setting a user-defined number
-  of data substreams/subfiles at scale. See examples 5, 9, 12, 16.
-
- Added VTU output of boundary elements and attributes and parallel VTU (PVTU)
-  output of parallel meshes for visualization using ParaView.
-
- The integration order used in the ComputeLpError and ComputeElementLpError
-  methods of class GridFunction has been increased.
-
- Various other simplifications, extensions, and bugfixes in the code.
-
- Renamed "Backend::DEBUG" to "Backend::DEBUG_DEVICE" to avoid conflicts,
-  as DEBUG is sometimes used as a macro.
-
- Change the IntegrationRule inside VectorDiffusionIntegrator to use the same
-  quadrature as DiffusionIntegrator.
-
-
-Version 4.1, released on March 10, 2020
-=======================================
-
-Starting with this version, the MFEM open source license is changed to BSD-3.
-
-Improved GPU capabilities
-------------------------
- Added initial support for AMD GPUs based on HIP: a C++ runtime API and kernel
-  language that can run on both AMD and NVIDIA hardware.
-
- Added support for Umpire, a resource management library that allows the
-  discovery, provision, and management of memory on machines with multiple
-  memory devices like NUMA and GPUs, see https://github.com/LLNL/Umpire.
-
- GPU acceleration is now available in 3 additional examples: 3, 9 and 24.
-
- Improved RAJA backend and multi-GPU MPI communications.
-
- Added a "debug" device designed specifically to aid in debugging GPU code by
-  following the "device" code path (using separate host/device memory spaces and
-  host <-> device transfers) without any GPU hardware.
-
- Added support for matrix-free diagonal smoothers on GPUs.
-
- The current list of available device backends is: "ceed-cuda", "occa-cuda",
-  "raja-cuda", "cuda", "hip", "debug", "occa-omp", "raja-omp", "omp",
-  "ceed-cpu", "occa-cpu", "raja-cpu", and "cpu".
-
- The MFEM memory manager now supports different memory types, associated with
-  the following memory backends:
-  * Default host memory, using standard C++ new and delete,
-  * CUDA pointers, using cudaMalloc and HIP pointers, using hipMalloc,
-  * Managed CUDA/HIP memory (UVM), using cudaMallocManaged/hipMallocManaged,
-  * Umpire-managed memory, including memory pools,
-  * 32- or 64-byte aligned memory, using posix_memalign (WIN32 also supported),
-  * Debug memory with mmap/mprotect protection used by the new "debug" device.
-
-libCEED support
---------------
- Added support for libCEED, the portable library for high-order operator
-  evaluation developed by the Center for Efficient Exascale Discretizations in
-  the Exascale Computing Project, https://github.com/CEED/libCEED.
-
- This initial integration includes Mass and Diffusion integrators. libCEED GPU
-  backends can be used without specific MFEM configuration, however it is highly
-  recommended to use the "cuda" build option to minimize memory transfers.
-
- Both CPU and GPU modes are available as MFEM device backends (ceed-cpu and
-  ceed-cuda), using some of the best performing CPU and GPU backends from
-  libCEED, see the sample runs in examples 1 and 6.
-
- NOTE: The current default libCEED GPU backend (ceed-cuda) uses atomics and
-  therefore is non-deterministic.
-
-Partial assembly and matrix-free discretizations
------------------------------------------------
- The support for matrix-free methods on both CPU and GPU devices based on a
-  partially assembled operator decomposition was extended to include:
-  * DG integrators, (for now only in the Gauss-Lobatto basis), see Example 9,
-  * H(curl) bilinear forms, see Example 3,
-  * vector mass and vector diffusion bilinear integrators,
-  * convection integrator with improved performance,
-  * gradient and vector divergence integrators for Stokes problems,
-  * initial partial assembly mode for NonlinearForms.
-
- Diagonals of partially assembled operators can now be computed efficiently.
-  See the new methods AssembleDiagonal in BilinearForm, AssembleDiagonalPA in
-  BilinearFormIntegrator and the implementations in fem/bilininteg_*.cpp.
-
- In many examples, the partial assembly algorithms provide significantly
-  improved performance, particularly in high-order 3D runs on GPUs.
-
-Meshing improvements
--------------------
- The algorithms for mesh element numbering were changed to have significantly
-  better caching and parallel partitioning properties. Both initial (see e.g.
-  Mesh::GetHilbertElementOrdering) and ordering after uniform refinement were
-  improved. NOTE: new ordering can have a round-off effect on solver results.
-
- Added support for non-conforming AMR on both prisms and tetrahedra, including
-  coarsening and parallel load balancing. Anisotropic prism refinement is only
-  available in the serial version at the moment.
-
- The TMOP mesh optimization algorithms were extended to support r-adaptivity.
-  Target matrices can now be constructed either via a given analytical function
-  (e.g. spatial dependence of size, aspect ratio, etc., for each element) or via
-  a (Par)GridFunction specified on the original mesh.
-
- The TMOP algorithms were also improved to support non-conforming AMR meshes.
-
- Added support for creating refined versions of periodic meshes, making use of
-  the new L2ElementRestriction class. This class also allows for computing
-  geometric factors on periodic meshes using partial assembly.
-
-Discretization improvements
---------------------------
- Added support for GSLIB-FindPoints, a general high-order interpolation utility
-  that can robustly evaluate a GridFunction in an arbitrary collection of points
-  in physical space. See INSTALL for details on building MFEM with GSLIB, and
-  miniapps/gslib for examples of how to use this feature.
-
- Added support for complex-valued finite element operators and fields using a
-  2x2 block structured linear system to mimic complex arithmetic. New classes
-  include: ComplexGridFunction, SesquilinearForm, ComplexLinearForm, and their
-  parallel counterparts.
-
- Added second order derivatives of NURBS shape functions.
-
- Added support for serendipity elements of arbitrary order on affinely-mapped
-  square elements. Basis functions for these elements can be visualized using
-  an option in the display-basis miniapp.
-
- Two integrators related to Stokes problems, (Q grad u, v) and (Q div v, u),
-  where u and the components of v are in H1, were added/modified to support full
-  and partial assembly modes. See the new GradientIntegrator and the updated
-  VectorDivergenceIntegrator classes in fem/bilininteg.hpp, as well as the PA
-  kernels in fem/bilininteg_gradient.cpp and fem/bilininteg_divergence.cpp.
-
- Added a nonlinear vector valued convection integrator (Q u \cdot grad u, v)
-  where u_i and v_i are in H1. This form occurs e.g. in the Navier-Stokes
-  equations. The integrator supports the partial assembly mode for its
-  action. In full assembly mode we also provide the GetGradient method that
-  computes the linearized version of the integrator.
-
- Added a new method, MixedBilinearForm::FormRectangularLinearSystem, that can
-  be used to impose boundary conditions on the non-square off-diagonal blocks of
-  a block operator (similar to FormLinearSystem in the square case).
-
-Linear and nonlinear solvers
----------------------------
- Added support for Ginkgo, a high-performance linear algebra library for GPU
-  and manycore nodes, with a focus on sparse solution of linear systems. For
-  more details see linalg/ginkgo.hpp and the example code in examples/gingko.
-
- Added support for HiOp, a lightweight HPC solver for nonlinear optimization
-  problems, see class HiOpNLPOptimizer and the example codes in examples/hiop.
-
- Added a general interface for specifying and solving nonlinear constrained
-  optimization problems through the new classes OptimizationProblem and
-  OptimizationSolver, see linalg/solver.hpp.
-
- Added a block ILU(0) preconditioner for DG-type discretizations. Example 9
-  (DG advection) now takes advantage of this for implicit time integration.
-
- New time integrators: Adams-Bashforth, Adams-Moulton and several integrators
-  for 2nd order ODEs, see the new Example 23.
-
- Added a LinearSolve(A,X) convenience method to solve dense linear systems. In
-  the trivial cases, i.e., square matrices of size 1 or 2, the system is solved
-  directly, otherwise, LU factorization is employed.
-
-New and updated examples and miniapps
-------------------------------------
- Added a collection of 7 playful miniapps in miniapps/toys that illustrate the
-  meshing and visualization features of the library in more relaxed settings.
-  The toys include simulations of cellular automata, Rubik's cube, Mandelbrot
-  set, a tool to convert any image to mfem mesh, and more.
-
- Added 8 new example codes:
-  * Example 22/22p demonstrates the use of the new complex-valued finite element
-    operators by defining and solving a family of time-harmonic PDEs related to
-    damped harmonic oscillators.
-  * Example 23 solves a simple 2D/3D wave equation with the new second order
-    time integrators.
-  * Example 24/24p demonstrates usage of mixed finite element spaces in bilinear
-    forms. Partial assembly is supported in this example.
-  * A version of Example 1 in examples/ginkgo demonstrating the use of the
-    Gingko interface to solve a linear system.
-  * A version of Example 9/9p in examples/hiop demonstrating the nonlinear
-    constrained optimization interface and use of the SLBQP and HiOp solvers.
-
- Added two new miniapps: Find Points and Field Diff in miniapps/gslib that show
-  how GSLIB-FindPoints can be used to interpolate a (Par) GridFunction in an
-  arbitrary number of physical space points in 2D and 3D. The GridFunction must
-  be in H1 and in the same space as the mesh that is used to find the points.
-
- Added a simple miniapp, Get Values, that extracts field values at a set of
-  points, from previously saved data via DataCollection classes.
-
- Several examples and miniapps were updated:
-  * Added device support in Example 3/3p and Example 9/9p.
-  * Example 1/1p and Example 3/3p now use diagonal preconditioning in partial
-    assembly mode.
-  * Example 9/9p now supports implicit time integration, using the new block
-    ILU(0) solvers as preconditioners for the linear system.
-  * The mesh-optimizer and pmesh-optimizer miniapps now include the new
-    r-adaptivity capabilities of TMOP. They were also updated to support mesh
-    optimization on non-conforming AMR meshes.
-  * New options to reorder and partition the mesh and boundary attribute
-    visualization (key 'b') are now available in the mesh-explorer miniapp.
-
- Collected object files from the miniapps/common directory into a new library,
-  libmfem-common for the convenience of application developers. The new library
-  is now used in several miniapps in the electromagnetic and tools directories.
-
-Improved testing
----------------
- Added a large number of unit tests in the tests/unit directory, including
-  several parallel unit tests.
-
- Added a new directory, tests/scripts, with several shell scripts that perform
-  simple checks on the code including: code styling, documentation formatting,
-  proper use of .gitignore, and preventing the accidental commit of large files.
-
- It is recommended that developers run the above tests scripts (via the runtest
-  script) before pushing to GitHub. See the README file in tests/scripts.
-
- The Travis CI settings have been updated to include an initial Checks stage
-  which currently runs the code-style, documentation and gitignore test scripts,
-  as well as a final stage for optional checks/tests which currently runs the
-  branch-history script.
-
-Miscellaneous
-------------
- Added support for output in the ParaView XML format. Both low-order and
-  high-order Lagrange elements are supported. Output can be in ASCII or binary
-  format. The binary output can be compressed if MFEM is compiled with zlib
-  support (MFEM_USE_ZLIB). See the new ParaViewDataCollection class and the
-  updated Examples 5/5p and 9/9p.
-
- Upgraded the SUNDIALS interface to utilize SUNDIALS 5.0. This necessitated a
-  complete rework of the interface and requires changes at the application
-  level. Example usage of the new interface can be found in examples/sundials.
-
- Switched from gzstream to zstr for the implementation of zlib-compressed C++
-  output stream. The build system definition now uses MFEM_USE_ZLIB instead of
-  MFEM_USE_GZSTREAM, but the code interface (e.g. ofgzstream) remains the same.
-
- Various other simplifications, extensions, and bugfixes in the code.
-
-API changes
-----------
- In the enum classes MemoryType and MemoryClass, "CUDA" was renamed to "DEVICE"
-  which now denotes either "CUDA" or "HIP" depending on the build configuration.
-  In the same enum classes, "CUDA_UVM" was renamed to "MANAGED".

+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>

 MFEM is a modular parallel C++ library for finite element methods. Its goal is
-to enable high-performance scalable finite element discretization research and
-application development on a wide variety of platforms, ranging from laptops to
-supercomputers.
+to enable the research and development of scalable finite element discretization
+and solver algorithms through general finite element abstractions, accurate and
+flexible visualization, and tight integration with the hypre library.

+MFEM is commonly used as a "finite element to linear algebra translator", since
+it can take a problem described in terms of finite element-type objects, and
+produce the corresponding linear algebra vectors and sparse matrices. In order
+to facilitate this, MFEM uses compressed sparse row (CSR) sparse matrix storage
+and includes simple smoothers and Krylov solvers, such as PCG, MINRES and GMRES,
+as well as support for sequential sparse direct solvers from the SuiteSparse
 library. Nonlinear solvers (the Newton method), eigensolvers (LOBPCG), and
 several explicit and implicit Runge-Kutta time integrators are also available.

 MFEM supports MPI-based parallelism throughout the library, and can readily be
-used as a scalable unstructured finite element problem generator. As of version
-4.0, MFEM offers initial support for GPU acceleration, and programming models,
-such as CUDA, OCCA, RAJA and OpenMP. MFEM-based applications require minimal
-changes to switch from a serial to a high-performing MPI-parallel version of the
-code, where they can take advantage of the integrated linear solvers from the
-hypre library.  Comprehensive support for other external packages, e.g. PETSc
-and SUNDIALS is also included, giving access to many additional linear and
-nonlinear solvers, preconditioners, time integrators, etc.

-// Description:  This example code demonstrates the use of MFEM to define a
-//               simple finite element discretization of the Laplace problem
-//               -Delta u = 1 with homogeneous Dirichlet boundary conditions.
-//               Specifically, we discretize using a FE space of the specified
-//               order, or if order < 1 using an isoparametric/isogeometric
-//               space (i.e. quadratic for quadratic curvilinear mesh, NURBS for
-//               NURBS mesh, etc.)
-//
-//               The example highlights the use of mesh refinement, finite
-//               element grid functions, as well as linear and bilinear forms
-//               corresponding to the left-hand side and right-hand side of the
-//               discrete linear system. We also cover the explicit elimination
-//               of essential boundary conditions, static condensation, and the
-//               optional connection to the GLVis tool for visualization.
