-  - Building and caching dependencies: HYPRE, METIS, LSAN suppression file, and LLVM libcxx.
-  - Launching fine-grained jobs for serial (ASAN, MSAN, UBSAN) and parallel (ASAN, UBSAN) sanitizers.
- `sanitize-tests.yml` is a reusable workflow accepting `par` mode (`true` for parallel) and `sanitizer` (ASAN, MSAN, or UBSAN) as inputs. It executes the following jobs:
-  - **Build**: Compiles the MFEM library with specified parallel and sanitizer settings.
-  - **Check**: Runs verification checks.
-  - Parallel jobs to test the following: **Examples**, **Miniapps** and **Unit tests**
-
-The workflow leverages composite actions in `.github/actions/sanitize/`:
-
- `config`: Centralizes settings for the sanitizer workflow.
- `mfem`: Manages the MFEM library build process.
- `mpi`: Installs MPI and applies additional compilation flags.
- `restore`: Restores the testing environment state.
- `setup`: Builds or restores cached dependencies.

-Version 4.8.1 (development)
+Version 4.7.1 (development)
 ===========================

-Starting with this version, MFEM requires a C++17 compiler.
-
-Discretization improvements
---------------------------
- Introduced dFEM: a new MFEM capability for Automatic Differentiation (AD) of
-  nonlinear finite element operators, based on Enzyme or dual numbers AD at
-  quadrature points. These features are part of the new mfem::future namespace
-  and some of the API can change in the future. See the new dFEM minimal surface
-  miniapp in the miniapps/dfem/ directory for illustration of dFEM's use.
-
- Using Enzyme for AD in MFEM is tested with clang v19 and requires clang/LLVM
-  built with plugin support. See INSTALL for more details.
-
- In the ParMoonolith integration, added support for variational resampling of
-  H1 vector fields.
-
- Added support for boundary integration to the hyperbolic framework. In this
-  regard, new classes `BdrHyperbolicDirichletIntegrator` and
-  `BoundaryHyperbolicFlowIntegrator` have been introduced for implementation
-  of weak Dirichlet boundary conditions with a general flux or for the linear
-  case respectively.
-
- Added method to compute piecewise linear bounds on high-order functions on
-  tensor-product elements.
-
- Parallel anisotropic refinement of hexahedral meshes is now supported,
-  provided that neighboring hexahedra are not refined in conflicting directions.
-  A new ParMesh method is added to check for such conflicts, before refinement.
-
-Meshing improvements
--------------------
-
- Introduced NC-patch NURBS meshes, which are conforming element-wise but allow
-  for nonconforming patch topology. This new mesh format supports element
-  spacing formulas for refinement, as well as local refinement factors for a
-  subset of knot vectors.
-
- Added support for higher order meshes in Mesh::MakeSimplicial and
-  ParMesh::MakeSimplicial.
-
- Added a new miniapp for interpolating a surface grid of points in 3D using a
-  smooth NURBS surface, that can then be sampled at arbitrary resolution while
-  staying close to the original geometry. See miniapps/nurbs/nurbs_surface.
-
-GPU computing
-------------
- The function Vector::SetSubVector(const Array<int> &, const real_t) now
-  executes on device if either the vector or the array have the device flag
-  set. This is most often used for setting constant essential boundary
-  conditions. A new function Vector::SetSubVectorHost has been added in cases
-  where host execution is always needed (e.g. when the DOFs array is small).
-
- Introduced MFEM_FOREACH_THREAD_DIRECT, which directly maps loop tasks to GPU
-  threads, assigning one task per thread.
-
- Implemented a GPU-accelerated matrix-free AMR derefinement `GridFunction`
-  update operator. This supports mixed geometry meshes and variable order
-  spaces, and is the default derefinement operator constructed by
-  `FiniteElementSpace::Update` and `ParFiniteElementSpace::Update`.
-  The operator requires `FiniteElementSpace::Nonconforming() == true`.
- Added new method: GridFunction::GetGradients, with GPU support, for computing
-  the gradients of a GridFunction on all elements.
- Added GPU support in GradientGridFunctionCoefficient and
-  InnerProductCoefficient by implementing their Project methods.
-
-New and updated examples and miniapps
-------------------------------------
- Added miniapps to demonstrate an implementation of the absolute-value
-  L(1)-Jacobi preconditioners in partially assembled operators. This includes
-  Multigrid wrapper to demonstrate the effectiveness of these Jacobi-type
-  operators as smoothers.
-  These miniapps can be found in `miniapps/diag-smoothers`.
-
- Added a new miniapp (meshing/mesh-bounding-boxes) that computes the bounding
-  boxes for each element of a given mesh, and the bounds on the determinant of
-  the Jacobian of the transformation.
-
- Added a new miniapp (tools/gridfunction-bounds) to compute piecewise linear
-  bounds on a given high-order grid function.
-
- Added a new miniapp (electromagnetics/lorentz) which computes the trajectory
-  of a charged particle, subject to Lorentz forces, in electrostatic and/or
-  magnetostatic fields as computed by the volta or tesla miniapps.
-
-API changes:
-----------
- mfem::internal::tensor and mfem::internal::dual have been moved to
-  mfem::future::tensor and mfem::future::dual.
-
- API addition: in class `Operator`, added virtual functions: `AbsMult`, and
-  `AbsMultTranspose`; in class `Vector`, added `Abs` and `Pow`.
-
-Miscellaneous
-------------
- Added the "gpu", "raja-gpu", and "ceed-gpu" backend aliases/shortcuts which
-  automatically select between CUDA or HIP.
-
- The CUDA-specific names used by some of the unit tests like 'cunit_tests' and
-  'pcunit_tests' were replaced by names using 'gpu' instead of 'c' (short for
-  CUDA) or 'cuda'. These tests automatically run the CUDA/HIP tests based on the
-  MFEM build configuration.
-
- Added the option to enable GPU-aware MPI in MFEM using the environment
-  variable 'MFEM_GPU_AWARE_MPI' set to any value. Setting this environment
-  variable is an alternative to calling 'Device::SetGPUAwareMPI(true)'.
-
- Added parallel Address Sanitizer, serial and parallel Undefined Behavior
-  Sanitizer and serial Memory Sanitizer GitHub actions tests on Ubuntu.
-
- FindPointsGSLIB has a new constructor that accepts the mesh object and
-  internally calls the Setup() method so that the user does not have to.
-  The FreeData() method has also been moved to the destructor so the user does
-  not need to manually free-up the memory if the destructor is called before
-  MPI_Finalize().
-
-Version 4.8, released on Apr 9, 2025
-====================================
-
-Discretization improvements
---------------------------
- Added high-order basis functions on pyramid-shaped elements for all spaces in
-  the de Rham complex based on the paper "Orientation embedded high order shape
-  functions for the exact sequence elements of all shapes" by Fuentes, Keith,
-  Demkowicz and Nagaraj (doi.org/10.1016/j.camwa.2015.04.027). Positive basis
-  functions (Bernstein basis) for H1 and L2 on pyramids were also added.
-
- Added support for parallel p- and hp-refinement on quad/hex meshes. For hp, we
-  currently support only isotropic refinement with L2 or H1 spaces. See the new
-  miniapps hpref and phpref in the miniapps/meshing/ directory.
-
- Added several improvements for hyperbolic problems:
-  * Assembly of Jacobians in HyperbolicFormIntegrator
-  * Component-wise upwinded flux (ComponentwiseUpwindFlux)
-  * Average fluxes in NumericalFlux (formerly RiemannSolver) and FluxFunction
-
- Added convenience methods to class FiniteElementSpace to directly identify all
-  degrees of freedom on the exterior faces of the domain, without referencing
-  boundary element attributes (GetExteriorVDofs and GetExteriorTrueDofs).
-
- Altered (Par)GridFunction::Compute*Error functions to ensure they return
-  non-negative values and therefore behave as "norms".
-
- SubMesh and ParSubMesh have been extended to work on nonconforming meshes.
-  Extracting volume and exterior surface submeshes are both supported.
-
- LinearFormIntegrator, BilinearFormIntegrator and NonlinearFormIntegrator now
-  inherit from a base class Integrator that centralizes the logic for selecting
-  quadrature rules. This includes a virtual method GetDefaultIntegrationRule,
-  which should be favored over directly defining a default integration rule in
-  the element-level assembly routines. The latter is still possible, by leaving
-  the new virtual method as its default base implementation of returning NULL.
-
- Added NURBS-based H(div) and H(curl) elements in 2D and 3D. Currently only for
-  single patch meshes in serial.
-
- Refactored ALGOIM cut integration rules. The interface is unified with the
-  interface for moment based cut integration rules.
-
- FiniteElementSpace has new methods to directly set the prolongation and
-  restriction operators to user-specified sparse matrices.
-
- Added support for H(div) spaces in class QuadratureInterpolator. Currently only
-  (vector) VALUES, (vector) PHYSICAL_VALUES, and PHYSICAL_MAGNITUDES evaluations
-  are implemented.
-
- Added support for boundary constraints to class Hybridization.
-
- Added support for custom interpolation procedure in FindPointsGSLIB.
-
- Added GSLIB-based gather-scatter operator.
-
-Meshing improvements
--------------------
- Added support for nonuniform anisotropic mesh refinement on serial quad/hex
-  meshes with arbitrary spacing in each direction. This enables in particular
-  3:1 refinement, as demonstrated in the new meshing miniapp ref321.
-
- Added capabilities for optimization and adaptation of periodic meshes with
-  TMOP. The internals of TMOP were modified so that the optimization problem is
-  always solved with respect to mesh displacements.
-
- New convenience methods for manipulating boundary attribute markers in class
-  Mesh: MarkExternalBoundaries, MarkNamedBoundaries, UnmarkInternalBoundaries
-  and UnmarkNamedBoundaries. See Examples 1/1p and 11p for basic usage.
-
- Added a new method, GetExteriorFaceMarker, to the serial and parallel mesh
-  classes for identifying faces on the exterior of the mesh irrespective of
-  their presence in the list of "boundary elements".
-
- Added native AD support for computing the derivatives of numerous TMOP metrics
-  that didn't have first or second derivative implementations.
-
- Added ExodusII output capability which can handle in particular pyramid and
-  wedge element types. Mixed meshes are also supported.
-
- Added InverseElementTransformation::InitGuessType::EdgeScan as an alternative
-  initial guess type. This guess type tries solving with multiple initial guesses
-  along the r/s/t=0 edges of the element until a valid solution is found or all
-  initial guess points are exhausted.
-
- Added new convenience constructors for NURBS patches and knot vectors.
-
-GPU computing
-------------
- Extended FindPointsGSLIB to support general field interpolation on GPUs. Note
-  that this requires that switch from gslib v1.0.7 to v1.0.9.
-
- 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 method AddSpecialization in
-  classes DiffusionIntegrator and MassIntegrator (this functionality may be
-  added to more integrators in the future).
-
- Added BatchInverseElementTransformation to batch InverseElementTransformation
-  searches. Batch searches are currently limited to meshes with a single element
-  geometry type of SEGMENT, SQUARE, or CUBE. Additional element geometry types
-  may be added in the future. Mixed element order meshes are supported. Batch
-  searches can be performed on the CPU (serial per MPI rank) or GPU. Embedded
-  elements (SEGMENT in 2D/3D space or SQUARE in 3D space) are supported, however
-  the existing solvers may struggle to find a valid solution.
-
- 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. For higher performance, users can
-  then add specializations for these kernels.
-
- Element assembly kernels have been added for low-order refined -> high-order
-  transfer operators. New kernels can be offloaded as device kernels. Example
-  usage may be found in lor-transfer.cpp in the miniapps/tools/ directory.
-
- Added GPU acceleration and element assembly for DivDivIntegrator and
-  NormalTraceJumpIntegrator.
-
- Allow BlockLowerTriangularPreconditioner to run on GPU.
-
- Use device vectors in GMRES, FGMRES and other iterative methods.
-
-Linear and nonlinear solvers
----------------------------
- Added GPU acceleration of the algebraic hybridization solver for grad-div
-  problems in H(div). See Example 4.
-
- Added a self-contained implementation of the Method of Moving Asymptotes (MMA)
-  for solving optimization problems.
-
- Added support for SUNDIALS v7. See the section "API changes" for some small
-  changes related to this new version.
-
- Changed the name of class IterativeSolverMonitor to IterativeSolverController,
-  which now allows for specifying convergence by a user defined criterion. For
-  backward compatibility, the old name is still available.
-
- Refactored the ARKStepSolver class (ARKODE interface) to use the Mult() method
-  of TimeDependentOperator only when the associated ODE operator is expressed in
-  explicit form (i.e., TimeDependentOperator::isExplicit()), otherwise the
-  method 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 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.
-
-New and updated examples and miniapps
-------------------------------------
- Added an MFEM example for the eikonal equation (examples/ex40) based on the
-  proximal Galerkin method introduced by Keith and Surowiec.
-
- Added miniapps to demonstrate the H(div) and H(curl) NURBS elements.
-
- Fixed element visualization in the Mesh explorer miniapp.
-
- Added a command line option to all miniapps (-p or --send-port) for
-  specifying the GLVis server socket port (19916 by default).
-
- Added a new toy miniapp that animates an interesting fidget spiral cone toy.
-  See miniapps/toys/spiral.cpp.
-
-Miscellaneous
-------------
- 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.
-
- Updated the minimum CMake version requirements:
-  * CMake >= 3.12 for CPU builds,
-  * CMake >= 3.17 for CUDA builds, and
-  * CMake >= 3.14 for HIP builds (CMake >= 3.12 may work as well, not tested).
-
- Various other simplifications, extensions, and bugfixes in the code.
-
-API changes
-----------
- In class GridFunction, fec was renamed to fec_owned.
-
- RiemannSolver was renamed to NumericalFlux (the old name has been deprecated
-  through typedef).
-
- API changes due to 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.
-
- TMOP_Metric_skew2D has been marked as deprecated.
