                                https://mfem.org
 
 
-Version 4.7.1 (development)
-===========================
-- Refactored ALGOIM cut integration rules. The interface is unified with
-  the interface for moment based cut integration rules.
-- Altered (Par)GridFunction::Compute*Error functions to ensure they return
-  non-negative values and therefore behave as "norms".
-
-Discretization improvements
----------------------------
-- Added NURBS-based H(div) and H(curl) elements in 2D and 3D. Only on single
-  patch meshes. Only implemented for serial computations.
-
-- Added support for boundary constraints to the hybridization class.
-
-- Added support for external boundary submeshes with nonconformal mesh adaptation.
-
-- Added assembly of Jacobians to `HyperbolicFormIntegrator`.
-
-- Added average fluxes to `NumericalFlux` (formerly `RiemannSolver`)
-  and `FluxFunction`.
-
-- Added component-wise upwinded flux (`ComponentwiseUpwindFlux`).
-
-- Added support for H(div) spaces in class QuadratureInterpolator. For now, only
-  (vector) VALUES, (vector) PHYSICAL_VALUES, and PHYSICAL_MAGNITUDES evaluations
-  are implemented. [PR #4669]
-
-Meshing improvements
---------------------
-- Added native AD support for numerous TMOP metrics that didn't have first or
-  second derivative implementations.
-
-- The ExodusII reader now handles pyramid and wedge element types. Mixed meshes
-  are also supported.
-
-- Added support for nonuniform anisotropic (nonconforming) mesh refinement with
-  arbitrary spacing in each direction, for quadrilateral (2D) and hexahedral
-  (3D) meshes. This enables in particular 3:1 refinement, as demonstrated in the
-  new meshing miniapp ref321.
-
-New and updated examples and miniapps
--------------------------------------
-- Added miniapps to demonstrate the H(div) and H(curl) NURBS elements.
-
-- Added an MFEM example for the eikonal equation. This new solver is based on
-  the proximal Galerkin method introduced by Keith and Surowiec.
-
-- Added a new toy miniapp that animates an interesting fidget spiral cone toy.
-  See miniapps/toys/spiral.cpp.
-
-- Added a command line option to all miniapps (`-p` or `--send-port`) for
-  specifying the GLVis server socket port (19916 by default).
-
-GPU computing
--------------
-- Added support for GPU-accelerated batched linear algebra (using cuBLAS,
-  hipBLAS, MAGMA, or native MFEM functionality) through the BatchedLinAlg class.
-
-- A new GPU kernel dispatch mechanism was introduced. Users can instantiate
-  specialized kernels for specific combinations of (for example) polynomial
-  degree and number of quadrature points using
-  `DiffusionIntegrator::AddSpecialization` and
-  `MassIntegrator::AddSpecialization` (this functionality may be added to more
-  integrators in the future).
-
-- Calls to slower fallback kernels can be reported to `mfem::err` by setting
-  the environment variable `MFEM_REPORT_KERNELS` to any value other than `NO`
-  or by explicitly calling `KernelReporter::Enable`. Users can then add
-  specializations for these kernels to achieve higher performance.
-
-- Element assembly kernels have been added for low-order refined to
-  high-order transfer operators. New kernels can be offloaded as device
-  kernels. Example usage may be found in lor-transfer.cpp under miniapps/tools.
-
-- Added support for GPU accelerated FindPointsGSLIB. Note that this will require
-  the users to switch from gslib v1.0.7 to v1.0.9.
-
-- Allow BlockLowerTriangularPreconditioner to run on GPU.
-
-- Use device vectors in GMRES, FGMRES and other iterative methods.
-
-Miscellaneous
--------------
-- Added support for SUNDIALS v7. See the section "API changes" for some small
-  changes related to this new version.
-
-- Refactored the `ARKStepSolver` class (ARKODE interface) to use
-  `TimeDependentOperator::Mult` only when the associated ODE operator is
-  expressed in explicit form (i.e., `TimeDependentOperator::isExplicit()`),
-  otherwise `TimeDependentOperator::ExplicitMult` is used. A check has been
-  added to `ARKStepSolver` to verify that the associated ODE operator is not in
-  explicit form when a mass matrix solver is enabled via a call to either the
-  `UseMFEMMassLinearSolver` or `UseSundialsMassLinearSolver` methods. This is
-  because enabling a mass matrix solver assumes that F(u,k,t) = M k in the
-  associated ODE operator.
-
-- Added support for custom interpolation procedure in FindPointsGSLIB.
-
-- `FiniteElementSpace` has new methods to directly set prolongation and
-  restriction operators to arbitrary sparse matrices.
-
-- There are new convenience constructors for NURBS patches and knot vectors.
-
-- Added convenience methods for manipulating boundary attribute marker arrays;
-  `(Par)Mesh::MarkExternalBoundaries`, `(Par)Mesh::UnmarkInternalBoundaries`,
-  `(Par)Mesh::MarkNamedBoundaries`, and `(Par)Mesh::UnmarkNamedBoundaries`.
-  See examples `ex1.cpp`, `ex1p.cpp`, and `ex11p.cpp` for basic usage.
-
-- Added `(Par)Mesh::GetExteriorFaceMarker` for identifying faces on the
-  exterior of the mesh irrespective of their presence in the list of "boundary
-  elements".
-
-- Added methods to `(Par)FiniteElementSpace` to identify all degrees of freedom
-  located on the exterior of the domain without reference to the list of
-  "boundary elements"; `GetExteriorVDofs` and `GetExteriorTrueDofs`.
-
-- `LinearFormIntegrator` and `NonlinearFormIntegrator` (including
-  `BilinearFormIntegrator`) now all inherit from a base class `Integrator`
-  that combines some logic related to selecting quadrature rules. This includes
-  a virtual method `Integrator::GetDefaultIntegrationRule`, which should be
-  favored over directly defining a default integration rule in the element-level
-  assembly routines (although the latter is still possible, by leaving the new
-  virtual method as its default base implementation of returning `NULL`).
-
-- Updated the benchmarks (in tests/benchmarks) to work with the latest Google
-  Benchmarks classes (version 1.9.1). Renamed the MFEM_ENABLE_GOOGLE_BENCHMARKS
-  CMake option to just MFEM_ENABLE_BENCHMARKS.
-
-- Changed the name of `IterativeSolverMonitor` to `IterativeSolverController`
-  which now allows for declaring convergence by a user defined criterion. For
-  backward compatibility, the old name is still available.
-
-API changes
------------
-- API change: 'TMOP_Metric_skew2D' has been marked as deprecated.
-
-- API change: in class GridFunction, 'fec' was renamed to 'fec_owned'.
-
-- API change: `RiemannSolver` was renamed to `NumericalFlux` (the old name has
-  been been deprecated through typedef)
-
-- API change: support for SUNDIALS v7:
-  * the SUNDIALS types `realtype` and `booleantype` are no longer defined by v7
-    and therefore MFEM now uses the new type names `sunrealtype` and
-    `sunbooleantype`, respectively, which MFEM defines when using SUNDIALS < v6
-    where these types were not defined.
-  * The SUNDIALS macro `SUNLS_SUCCESS` and some other `*_SUCCESS` macros were
-    removed and replaced by `SUN_SUCCESS` in v7, so to avoid tedious checks for
-    SUNDIALS versions, MFEM now defines and uses the constant `SUN_SUCCESS` when
-    using SUNDIALS < v7.
-  * The constants `SUN_PREC_*`, introduced by SUNDIALS v6 are now introduced by
-    MFEM when using SUNDIALS < v6 to avoid tedious version checks.
-
-
-Version 4.7, released on May 7, 2024
-====================================
-
-- Added support for single precision (with corresponding hypre build). The MFEM
-  floating point type was generalized from `double` to `real_t`. For details see
-  https://github.com/orgs/mfem/discussions/4207.
-
-Meshing improvements
---------------------
-- Added the capability to partition (big) serial meshes in serial code, see the
-  new classes MeshPartitioner and MeshPart. This capability is also exposed as a
-  menu option in the mesh-explorer miniapp in miniapps/meshing.
-
-- Added named attribute sets and basic supporting methods to the Mesh class as a
-  convenient means of referring to sets of domain or boundary attribute numbers.
-  See the new Example 39/39p and data/compass.mesh.
-
-- Introduced formulas for refinement of patches in NURBS meshes. Refinement by
-  arbitrary integer factors is also enabled, e.g. in the mesh-explorer miniapp.
-  NURBS coarsening and knot removal are also introduced.
-
-- Added support for internal boundary elements in nonconforming meshes.
-
-- Added ExodusII output capability. The writer can handle first-order (Pyramid5,
-  Wedge6, Hex8, Tet4) and second-order FE types (Pyramid14, Wedge18, Hex27, Tet10).
-
-- The ReadCubit Genesis mesh importer has been rewritten to improve readability.
-
-Discretization improvements
----------------------------
-- Added a new nonlinear integrator, `HyperbolicFormIntegrator` that implements
-  both element-wise weak divergence and face-wise numerical flux for a general
-  system of hyperbolic conservation laws. To use the integrator for a specific
-  flux function, users can define a derived class of `FluxFunction`. Currently,
-  advection, Burgers, shallow-water and Euler equations (see Example 18/18p) are
-  available.
-
-- Added a capability to construct cut-surface and cut-volume IntegrationRules
-  through a moment-fitting approach. The cut is specified by the zero level set
-  of a Coefficient. See fem/intrules_cut.hpp and the new Example 38.
-
-- Introduced support for high-order nonconforming Nedelec elements on simplices.
-
-GPU computing
--------------
-- Added partial assembly and GPU support for the DG diffusion integrator.
-
-- Efficient GPU-accelerated LOR assembly is now supported on surface meshes.
-
-- Added functionality to automatically configure hypre's compute policy to match
-  MFEM's compute policy when hypre is built with GPU support. Requires version
-  hypre-2.31.0 or later.
-
-- Added support for full assembly on simplices.
-
-- Added partial assembly for linear elasticity (no sum factorization for now).
-
-- Added functionality for BilinearFormIntegrators to use kernels that work for
-  both tensor and unstructured elements.
-
-- The RAJA backend will use `seq_exec` for serial loop execution when RAJA
-  v2023.06.00 and beyond is detected as `loop_exec` is deprecated.
-
-- API change: The macro MFEM_HYPRE_FORALL (from hypre.hpp) which was intended
-  for internal use, has been removed and replaced by the function template
-  mfem::hypre_forall in general/forall.hpp.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new miniapp illustrating elastic contact based on the Tribol library,
-  (https://github.com/LLNL/Tribol). See miniapps/tribol.
-
-- Added a miniapp to demonstrate low order refined (LOR) block preconditioning
-  for linear elasticity on GPUs. See miniapps/solvers/lor_elast.
-
-- Added a new block solver in miniapp/solvers for the Darcy problem. The new
-  solver is based on a Bramble-Pasciak preconditioning. User can use and
-  implement their own preconditioner for the mass matrix.
-
-- Added a small miniapp for printing the shape functions of a KnotVector. See
-  miniapps/nurbs/nurbs_printfunc.cpp.
-
-- Added two new example codes: 38 and 39/39p described above. Substantially
-  updated Example 18/18p.
-
-- Added ODE solvers selection routines. This creates a uniformity across examples,
-  miniapps and other executables in regard to ODE(time-integrator) selection.
-
-- Added new mechanism for retrieving and setting state vectors in ODE solvers.
-  This is relevant for AB/AM and gen-alpha solvers.
-
-- Added ODEsolver/ODEsolver2 unit tests to verify order of convergence and
-  read/write functionality.
-
-Miscellaneous
--------------
-- Updated the Doxygen documentation style, which now requires Doxygen version
-  1.9.8 or later. See the doc/ directory.
-
-- Improved thread safety for global variables in the library, e.g. for IntRules,
-  RefinedIntRules, GlobGeometryRefiner, and FiniteElement::dof2quad_array.
-
-- PETSc integration now generally requires PETSc version 3.21 or later, though
-  depending on the functionality older versions may still work.
-
-- Various other simplifications, extensions, and bugfixes in the code.
-
-- Added GSLIB-based gather-scatter operator.
-
-
-Version 4.6, released on September 27, 2023
-===========================================
-
-- MFEM is now available in Homebrew and can be installed on a Mac with just
-  "brew install mfem". See https://formulae.brew.sh/formula/mfem.
-
-Meshing improvements
---------------------
-- Added asymptotically-balanced TMOP compound metrics 90, 94, 328, 338. A new
-  tool, tmop-metric-magnitude, can be used to track how metrics change under
-  geometric perturbations. See miniapps/tools.
-
-- Several NURBS meshing improvements:
-  * Support for free connectivity of NURBS patches allowing for more complex
-    patch configurations such as C-meshes.
-  * New methods to set and get attributes on NURBS patches and patch boundaries.
-  * The edge to knot map for NURBS meshes can be determined automatically. It is
-    no longer needed to specify this in the NURBS mesh.
-  * Added curve interpolation method for NURBS.
-  * See miniapps/nurbs for example meshes and miniapps.
-
-Discretization improvements
----------------------------
-- SubMesh and ParSubMesh have been extended to support the transfer of
-  Nedelec and Raviart-Thomas finite element spaces.
-
-- Added support for partial assembly on NURBS patches, and NURBS-patch sparse
-  matrix assembly. Patch matrix assembly includes the option to use reduced
-  approximate integration rules, computed by the newly implemented non-negative
-  least-squares (NNLS) solver.
-
-- Support for parallel transfer of H1 fields using the low-order refined (LOR)
-  transfer operators in L2ProjectionGridTransfer
-
-- Added KDTree class for 2D/3D set of points, which is then utilized in the new
-  KDTreeNodalProjection class to project a function defined on an arbitrary set
-  of points onto an MFEM grid function. This functionality is demonstrated in
-  the nodal-transfer miniapp. The current implementation is serial only. Further
-  extensions can include search in arbitrary dimensional spaces.
-
-- Added support for p-refined meshes in GSLIB-FindPoints.
-
-- Device kernels can now access device-specific DOF and quadrature limits using
-  the DofQuadLimits structure, allowing increased limits when executing on CPU.
-  The limits for the runtime selected device can be accessed in host code using
-  DeviceDofQuadLimits::Get(). The global constants MAX_D1D and MAX_Q1D are no
-  longer available.
-
-- Face restriction operators for Nedelec and Raviart-Thomas finite element
-  spaces are now supported through the ConformingFaceRestriction class.
-
-- VectorFEBoundaryFluxLFIntegrator is now supported on device/GPU.
-
-Linear and nonlinear solvers
-----------------------------
-- Updated the MUMPS interface to support multiple right-hand sides, block
-  low-rank compression, builds using 64-bit integers, and other improvements.
-
-- Added an interface to the MKL Pardiso sparse direct solver developed by Intel.
-  The interface provides a serial (OpenMP shared memory) version of Pardiso for
-  use with SparseMatrix. This complements the existing parallel (MPI distributed
-  memory) version already available through the CPardiso MFEM integration.
-
-- Added HIP support to the PETSc and SUNDIALS interfaces.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new H(div) solver miniapp demonstrating the use of a matrix-free
-  saddle-point solver methodology, suitable for high-order discretizations and
-  for GPU acceleration. Examples illustrating the solution of Darcy and grad-div
-  problems are included. See miniapps/hdiv-linear-solver.
-
-- Added new Discontinuous Petrov-Galerkin (DPG) miniapp which includes serial
-  and parallel examples for diffusion, convection-diffusion, acoustics and
-  Maxwell equations. The miniapp includes new classes such as (Par)DPGWeakForm,
-  (Par)ComplexDPGWeakForm and (Complex)BlockStaticCondensation. Three new
-  integrators are added in support of DPG systems: TraceIntegrator,
-  NormalTraceIntegrator and TangentTraceIntegrator. See miniapps/dpg.
-
-- Added a new miniapp that implements the SPDE method for generating Gaussian
-  random fields of Matern covariance. The resulting random field can be used,
-  e.g., to model material uncertainties. See miniapps/spde.
-
-- Added a new parallel LOR transfer miniapp, plor-transfer, which mirrors the
-  functionality of the serial LOR transfer miniapp. See miniapps/tools.
-
-- New serial miniapp, nodal-transfer, demonstrating the use of KDTree to map a
-  parallel grid function to a different parallel partitioning of the same mesh.
-
-- Added 3 additional TMOP miniapps in miniapps/meshing:
-  * Mesh-Quality evaluates quality using size, skewness, and aspect-ratio
-    computed from the Jacobian of the transformation.
-  * Mesh-Fitting can be used for interface and boundary fitting to implicit
-    domains defined using level-set functions.
-  * Fit-Node-Position fits selected mesh nodes to specified positions, while
-    maintaining overall mesh quality.
-
-- Added 4 new example codes:
-  * Example 34/34p solves a simple magnetostatic problem where source terms and
-    boundary conditions are transferred with SubMesh objects.
-  * Example 35p implements H1, H(curl) and H(div) variants of a damped harmonic
-    oscillator with field transfer using SubMesh objects.
-  * Example 36/36p demonstrates the solution of the obstacle problem with a new
-    finite element method (proximal Galerkin).
-  * Example 37/37p demonstrates topology optimization with MFEM.
-
-- Added a random refinement option to the mesh-explorer miniapp to assist users
-  in experimenting with nonconforming meshes.
-
-- Moved the distance solver methods from miniapps/shifted to miniapps/common.
-
-Miscellaneous
--------------
-- Improved lambda body debugging with the addition of mfem::forall functions.
-  These functions can take the place of the MFEM_FORALL macros, which have been
-  preserved for backwards compatibility.
-
-- Added an address sanitizer GitHub action for a serial build/test on Ubuntu,
-  based on Clang/LLVM (https://clang.llvm.org/docs/AddressSanitizer.html).
-
-- Reorganized files for bilinear form, linear form, and nonlinear form integrators
-  in the fem/integ/ subdirectory.
-
-- FiniteElementSpace::GetFE has been updated to abort instead of returning NULL for
-  an empty partition.
-
-- Various other simplifications, extensions, and bugfixes in the code.
-
-
-Version 4.5.2, released on March 23, 2023
-=========================================
-
-- Added support for pyramids in non-conforming meshes. Currently only isotropic
-  refinement is supported in this case.
-
-- Removed the support for the Mesquite toolkit. We recommend using MFEM's TMOP
-  functionality instead for mesh optimization. See the mesh-optimizer miniapp.
-
-- Added a fast normalization-based distance solver, see the Distance miniapp
-  in the miniapps/shifted/ directory.
-
-- Added a new meshing miniapp, Reflector, which reflects a high-order or NURBS
-  hexahedral mesh about a plane.
-
-- Updated logic in FindPointsGSLIB to ignore points found near (but outside) the
-  domain boundary.
-
-- Added an option to auto-balance compound TMOP metrics.
-
-- Fixed a bug in TMOP metric 301.
-
-- When using discontinuous (L2) spaces, use local (element-wise) L2 projection
-  as the coarsening operator for non-conforming AMR meshes.
-
-- Added support for GridFunction::GetGradients() and GetVectorGradient() on
-  face-neighbor elements.
-
-- Added support for pyramids in Gmsh meshes.
-
-- The Mesh Explorer miniapp can now save mesh files in the VisIt or ParaView
-  formats using the corresponding DataCollection. See option 'D' in the menu.
-
-- VisItDataCollection now correctly handles data collection names containing
-  underscores.
-
-- Added support for shared Windows builds with MSVC through CMake.
-  Developers note: this enhancement is facilitated by the addition of the macro
-  MFEM_EXPORT, see config.hpp for more details on its usage.
-
-- The following integrations have updated minimum version requirements:
-  * RAJA >= 2022.10.3
-
-API changes
------------
-- The implicit cast methods of class Vector to 'double *' and 'const double *'
-  have been deprecated and generate deprecation warnings if used. They will be
-  removed in a future release.
-
-- The methods Mesh::GetFaceBaseGeometry and Mesh::GetFaceGeometryType have been
-  deprecated, and Mesh::GetFaceGeometry (which provides identical functionality)
-  should be used instead.
-
-- VisItDataCollection::SetPadDigits() no longer alters the number of digits
-  used to represent the MPI rank because VisIt seems to require 6 digits.
-  This parameter can still be explicitly overridden with SetPadDigitsRank().
-
-
-Version 4.5, released on October 22, 2022
-=========================================
-
-Meshing improvements
---------------------
-- Added new SubMesh and ParSubMesh classes that can be used to extract a subset
-  of a given Mesh. These classes have the same functionality as Mesh and ParMesh
-  and work with all existing MFEM interfaces like finite element spaces etc.
-
-- Added a method, ParMesh::GetSerialMesh(), that reconstructs a partitioned
-  parallel mesh on a given single rank. Also, added ParMesh::PrintAsSerial(),
-  which saves the reconstructed serial mesh to a C++ stream on rank 0.
-
-- Added more 3D TMOP metrics, as well as specialized metrics for mesh
-  untangling and worst-case quality improvement.
-
-- Added a new method, Mesh::NodesUpdated, which should be called after the mesh
-  node coordinates have changed, e.g. after the mesh has moved. This is
-  necessary, for example, with device assembly of linear and bilinear forms.
-
-- Added support for mixed meshes and pyramids in GSLIB-FindPoints.
-
-Discretization improvements
----------------------------
-- Added full assembly and device support for several LinearForm integrators:
-  * DomainLF: (f, v)
-  * VectorDomainLF: ((f1,...,fn), (v1,...,vn))
-  * DomainLFGrad: (f, grad(v))
-  * VectorDomainLFGrad: ((f1x,f1y,f1z,...,fnx,fny,fnz), grad(v1,...,vn))
-  The device assembly of linear forms has to be explicitly enabled by calling
-  LinearForm::UseFastAssembly(true), otherwise the legacy linear form assembly
-  is used by default.
-
-- Added support for assembling low-order-refined matrices using a GPU-enabled
-  "batched" algorithm. The lor_solvers and plor_solvers now fully support GPU
-  acceleration with arbitrary user-supplied coefficients.
-
-- Added a new class FaceQuadratureSpace that allows for the construction of
-  QuadratureFunctions on the interior or boundary faces of a mesh.
-
-- Added a class CoefficientVector for efficient access of variable coefficient
-  values at quadrature points (in particular for GPU/device kernels).
-
-- Added WhiteGaussianNoiseDomainLFIntegrator: a LinearFormIntegrator class for
-  spatial Gaussian white noise.
-
-- Added a new Zienkiewicz-Zhu patch recovery-based a posteriori error estimator.
-  See fem/estimators.hpp.
-
-- Various fixes and improvements in LinearFormExtension.
-
-Linear and nonlinear solvers
-----------------------------
-- Added a new class DGMassInverse that performs a local element-wise CG
-  iteration to solve systems involving the discontinuous Galerkin mass matrix,
-  including support for device/GPU acceleration.
-
-- Added more flexibility to the constrained solver classes:
-  * PenaltyConstrainedSolver now allows for a vector of penalty parameters
-    (necessary for penalty contact)
-  * PenaltyConstrainedSolver and EliminationSolver can use GMRES or PCG
-  * All constraint solver classes can take a user-defined preconditioner
-
- - Added functions to toggle additional options for the SuperLU_Dist and Hypre
-   preconditioners (ParaSails, Euclid, ILU).
-
-- Added boundary elimination with device support for `SparseMatrix` and
-  `HypreParMatrix`.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new elasticity miniapp, Hooke, that showcases a low-level approach of
-  using MFEM to solve a nonlinear elasticity problem based on the fundamental
-  finite element operator decomposition. The miniapp also integrates with
-  automatic differentiation tools like a native dual number implementation or a
-  third party library such as Enzyme. See miniapps/elasticity for more details.
-
-- Added example for body-fitted volumetric and shape integration using the
-  Algoim library in miniapps/shifted.
-
-- Add a new example code, Example 33/33p, to demonstrate the solution of
-  spectral fractional PDEs with MFEM.
-
-Integrations, testing and documentation
----------------------------------------
-- Added a Dockerfile for a simple MFEM container, see config/docker/README.md.
-  More sophisticated developer containers are available in the new repo
-  https://github.com/mfem/containers.
-
-- Added support for the LLVM-based automatic differentiation tool Enzyme, see
-  https://github.com/EnzymeAD/Enzyme. Build system flags and a convenience
-  header are provided. The functionality and interaction are demonstrated in a
-  new miniapp in miniapps/elasticity.
-
-- Added support for partial assembly and fully matrix-free operators on mixed
-  meshes (different element types and p-adaptivity) through libCEED, including
-  device acceleration, e.g. with NVIDIA and AMD GPUs. The p-adaptivity is
-  currently limited to 2D serial meshes. All mixed element topologies are
-  supported in both serial and parallel.
-
-- Added support for ParMoonolith, https://bitbucket.org/zulianp/par_moonolith,
-  which provides parallel non-conforming, non-matching, variational, volumetric
-  mesh information transfer. With ParMortarAssember, fields can be exchanged
-  between arbitrarily distributed and unrelated finite element meshes in a
-  variationally consistent way.
-
-- Fully encapsulated SUNDIALS `N_Vector` object within the `SundialsNVector`
-  class by removing deprecated (e.g. `HypreParVector::ToNVector`) and
-  non-deprecated (e.g. `Vector::ToNVector`) functions in other classes.
-
-- New benchmark for the different assembly levels inspired by the CEED
-  Bake-Off Problems, see tests/benchmarks/bench_assembly_levels.cpp.
-
-- Added Windows 2022 CI testing with GitHub actions.
-
-Miscellaneous
--------------
-- The method SparseMatrix::EnsureMultTranspose() is now automatically called
-  by the methods AddMultTranspose(), MultTranspose(), and AbsMultTranspose().
-  Added a method with the same name to class HypreParMatrix which is also called
-  automatically by the HypreParMatrix::MultTranspose() methods.
-
-- Updated various MemoryUsage methods to return 'std::size_t' instead of 'long'
-  since the latter is 32-bit in Win64 builds.
-
-- When using `AssemblyLevel::FULL`, `FABilinearFormExtension::FormSystemMatrix`
-  outputs an `OperatorHandle` containing a `SparseMatrix` in serial, and an
-  `HypreParMatrix` in parallel (instead of a `ConstrainedOperator`).
-
-- In various places in the library, replace the use of 'long' with 'long long'
-  to better support Win64 builds where 'long' is 32-bit and 'long long' is
-  64-bit. On Linux and MacOS, both types are typically 64-bit.
-
-- The behavior of GridFunction::GetTrueVector() has been changed to not return
-  an empty true vector.
-
-- Added support for ordering search points byVDIM in FindPointsGSLIB.
-
-- Various other simplifications, extensions, and bugfixes in the code.

-# mfem Docker
-
-We provide a [Dockerfile.base](Dockerfile.base) to build an ubuntu base image,
-and a [Dockerfile](Dockerfile) to build a smaller one with a multi-stage build.
-You can use this image for a demo of using mfem! 🎉️
-
-Updated containers are built and deployed on merges to the main branch and releases.
-If you want to request a build on demand, you can [manually run the workflow](https://docs.github.com/en/actions/managing-workflow-runs/manually-running-a-workflow) thanks to the workflow dispatch event.
-
-## Usage
-
-We provide two containers, which you can either build or use directly from
-[GitHub packages](https://github.com/orgs/mfem/packages?repo_name=mfem).
-
- - `ghcr.io/mfem/mfem-ubuntu-base`: a "build from scratch" for mfem
- - `ghcr.io/mfem/mfem-ubuntu`: a quick build that uses the base container
-
-In the above, "ghcr.io" means "GitHub Container Registry" and
-is the [GitHub packages](https://github.com/features/packages) registry that supports
-Docker images and other OCI artifacts. 
-
-### Ubuntu
-
-> Use or build this container for a multi-stage, slimmer base to develop on top of mfem
-
-Note that this container is provided on GitHub packages [here](https://github.com/mfem/mfem/pkgs/container/mfem-ubuntu)
-so you don't need to build it. However, if you want to, you can do the following:
-
-```bash
-$ docker build -f config/docker/Dockerfile -t ghcr.io/mfem/mfem-ubuntu .
-```
-
-Note that this will pull the base image. If you want to rebuild it, see [ubuntu base](#ubuntu-base)
-below. Once you have built (or prefer to pull) you can shell into the container as follows:
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu
-```
-
-This smaller image has a view where everything is installed.
-
-```bash
-$ ls
-bin  etc  include  lib  libexec  sbin  share  var
-```
-
- - Examples are in share/mfem/examples
- - Examples are in share/mfem/miniapps
-
-Using this container, if you want to develop a tool that _uses_ mfem, you can find the libraries / includes in:
-
-```bash
-$ ls include/ | grep mfem
-mfem
-mfem-performance.hpp
-mfem.hpp
-```
-
-And yes, this is the working directory when you shell into the container!
-You can find the examples here:
-
-
-```bash
-cd share/mfem/examples
-```
-
-Try quickly setting the `LD_LIBRARY_PATH` so we can see the shared libraries
-we need:
-
-```bash
-export LD_LIBRARY_PATH=/opt/mfem-view/lib:$LD_LIBRARY_PATH
-```
-
-And then run:
-
-```bash
-$ ./ex0
-Options used:
-   --mesh ../data/star.mesh
-   --order 1
-Number of unknowns: 101
-   Iteration :   0  (B r, r) = 0.184259
-   Iteration :   1  (B r, r) = 0.102754
-   Iteration :   2  (B r, r) = 0.00558141
-   Iteration :   3  (B r, r) = 1.5247e-05
-   Iteration :   4  (B r, r) = 1.13807e-07
-   Iteration :   5  (B r, r) = 6.27231e-09
-   Iteration :   6  (B r, r) = 3.76268e-11
-   Iteration :   7  (B r, r) = 6.07423e-13
-   Iteration :   8  (B r, r) = 4.10615e-15
-Average reduction factor = 0.140201
-```
-
-You can also explore the "mini apps," also in share/mfem, but under miniapps.
-
-```bash
-# This is run from the examples directory
-$ cd ../miniapps
-```
-```bash
-$ ls
-CMakeLists.txt  common            meshing  nurbs        shifted  toys
-adjoint         electromagnetics  mtop     parelag      solvers
-autodiff        gslib             navier   performance  tools
-```
-
-And an example in "toys"
-
-```bash
-cd toys
-```
-```bash
-$ ./automata -no-vis
-Options used:
-   --num-steps 16
-   --rule 90
-   --no-visualization
-
-Rule:
- 111 110 101 100 011 010 001 000
-  0   1   0   1   1   0   1   0
-
-Applying rule...done.
-```
-
-Have fun! As a reminder, this container is ideal for developing your own
-applications that might use mfem, or having a nice environment to test out
-examples.
-
-
-### Ubuntu Base
-
-> Use this build for a development environment with spack and mfem
-
-This container is also [provided on GitHub packages](https://github.com/mfem/mfem/pkgs/container/mfem-ubuntu-base), 
-however you can build it locally too:
-
-```bash
-$ docker build -f config/docker/Dockerfile.base -t ghcr.io/mfem/mfem-ubuntu-base .
-```
-
-To shell into the container:
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu-base bash
-```
-
-Change directory to the mfem environment, setup spack, and activate the environment:
-
-```bash
-source /opt/spack/share/spack/setup-env.sh
-cd /opt/mfem-env/
-spack env activate .
-```
-
-Note that this environment is installing to the view at `/opt/view`. Since the environment
-knows to install mfem from `/code` this means that you could make changes in the container (or bind
-`/code` to your container) and then update spack:
-
-```bash
-# Note that concretization takes a hot minute!
-$ spack install
-```
-
-And if you want to load mfem:
-
-```bash
-$ spack load mfem
-$ env | grep mfem
-```
-
-In this development container, you can find the examples and miniapps alongside
-mfem under `/code`:
-
-```bash
-cd /code/examples
-```
-```bash
-$ ./ex0
-```
-```console
-Options used:
-   --mesh ../data/star.mesh
-   --order 1
-Number of unknowns: 101
-   Iteration :   0  (B r, r) = 0.184259
-   Iteration :   1  (B r, r) = 0.102754
-   Iteration :   2  (B r, r) = 0.00558141
-   Iteration :   3  (B r, r) = 1.5247e-05
-   Iteration :   4  (B r, r) = 1.13807e-07
-   Iteration :   5  (B r, r) = 6.27231e-09
-   Iteration :   6  (B r, r) = 3.76268e-11
-   Iteration :   7  (B r, r) = 6.07423e-13
-   Iteration :   8  (B r, r) = 4.10615e-15
-Average reduction factor = 0.140201
-```
-
-This container is likely ideal for someone that wants to develop mfem itself.
-For other use cases, we recommend using the slimmer image. As an example,
-if you want to develop with your own code base (and mfem as is in the container) 
-you can bind to somewhere else in the container (e.g., src)
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu-base -v $PWD:/code bash
