-# DESCRIPTION:
-###############################################################################
 # General GitLab pipelines configurations for supercomputers and Linux clusters
-# at Lawrence Livermore National Laboratory (LLNL).
-# This entire pipeline is LLNL-specific
-#
-# Important note: This file is a template provided by llnl/radiuss-shared-ci.
-# Remains to set variable values, change the reference to the radiuss-shared-ci
-# repo, opt-in and out optional features. The project can then extend it with
-# additional stages.
-#
-# In addition, each project should copy over and complete:
-# - .gitlab/custom-jobs-and-variables.yml
-# - .gitlab/subscribed-pipelines.yml
-#
-# The jobs should be specified in a file local to the project,
-# - .gitlab/jobs/${CI_MACHINE}.yml
-# or generated (see LLNL/Umpire for an example).

+# - Allocate/Release is where Dane resource are allocated/released once for all.
+# - Build and Test is where we build and MFEM for multiple toolchains.
+# - Baseline_checks gathers baseline-type test suites execution

-Version 4.9.1 (development)
+Version 4.8.1 (development)
 ===========================

-Discretization improvements
---------------------------
- Improved the gridfunction projection routines. Projections work for Scalar,
-  Vector and VectorFE, also NURBS versions. Optionally different types of
-  projections can be selected, default behaviour has not changed.
-
- Added methods to estimate function extremum using piecewise linear bounds +
-  recursive subdivision.
-
-Meshing improvements
--------------------
- Improved support for 1D NURBS meshes with variable order, including using
-  the patches construct for 1D NURBS meshes.
-
-New and updated examples and miniapps
-------------------------------------
- Electromagnetics/lorentz miniapp has been updated to leverage the ParticleSet
-  capability.
-
-
-Version 4.9, released on Dec 11, 2025
-=====================================
-
 Starting with this version, MFEM requires a C++17 compiler.

 Discretization improvements

  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.
+  miniapp in the miniapps/dfem/ directory for illustration of dFEM's use.

- Introduced initial support for particle methods in MFEM with new classes
-  Particle, ParticleSet and ParticleVector.
-  * Particle is a convenient interface for individual particle data.
-  * ParticleSet manages and stores particle data in a struct-of-arrays form,
-    carrying particle coordinates and IDs along with an arbitrary number of
-    Vector and integer data for each particle.
-  * ParticleVector is a Vector-derived container that stores vector data for an
-    arbitrary number of particles contiguously based on specified vdim/ordering.
-  See the new particle miniapps in miniapps/gslib/ and miniapps/fluids/navier/.
-
- Added a new miniapp and specialized AMG solver (AMGF) for optimization-based
-  contact mechanics. The miniapp solves large-scale frictionless contact using a
-  self-contained Interior Point (IP) solver, mortar-based contact constraints
-  provided by Tribol. The resulting linear systems are solved with the new AMGF
-  solver (see below). Benchmark examples include the two-block, ironing, and
-  beam-sphere problems. See the miniapps/contact/ directory.
-
- Added support for boundary integration to the hyperbolic framework. Two 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 a method to compute piecewise linear bounds on high-order functions on
-  tensor-product elements.
-
- Added support for interior face integration enabling DG methods in
-  ParMixedBilinearForm, ParNonlinearForm and ParBlockNonlinearForm.
+- 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.

- Introduced IMEX ODE solvers based on a split-operator framework. Added
-  examples ex41 and ex41p demonstrating IMEX DG/CG discretizations of the
-  convection–diffusion equation, with ex41p using DG LOR preconditioning.
+- 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
 --------------------
- The TMOP kernel hierarchy has been restructured to reduce compilation time.
-  Most large kernels have been split into smaller specific kernels for each
-  metric. The directory structure has been updated with assemble, metrics, mult
-  and tools subdirectories. New kernel dispatch and specialization system has
-  also been integrated. Unit tests have been revised to ensure --all tests pass.

 - 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.

- 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.
-
- Added support for higher order meshes in (Par)Mesh::MakeSimplicial.
-
-Linear and nonlinear solvers
----------------------------
- Added FilteredSolver: a base class for solvers with filtering. It handles
-  cases where a solver performs well except in small subspaces, by adding a
-  filtering step formulated as a subspace correction.
-
- Added AMGFSolver: a derived class of FilteredSolver, specialized for AMG with
-  Filtering (AMGF), providing robust preconditioning for linear systems arising
-  in constrained optimization problems such as frictionless contact.
-
-  Added 'GetResiduals' and 'GetFinalAbsResidualNorm' to 'HyprePCG',
-  'HypreGMRES', and 'HypreFGMRES' to get 'r' and '|r|_p'. Note that the latter
-  computes '|r|_p' from 'r' instead of returning a cached value like the
-  relative 'GetFinalResidualNorm'. These require Hypre >= 2.15.0.
-
-  Changed the default solver parameters for 'HyprePCG' to 'tol=1e-6' and
-  'max_iter=1000'. This matches the default parameters in Hypre 3.0.
-
-  Added various helper functions for querying/modifying Hypre solvers:
-  'HypreSmoother::GetType', 'HypreSmoother::GetSOROptions',
-  'HypreSmoother::GetPolyOptions', 'HypreSmoother::GetWindowParameters',
-  'HypreSmoother::IsOperatorSymmetric', 'HyprePCG::GetTol',
-  'HyprePCG::GetAbsTol', 'HyprePCG::GetMaxIter', 'HyprePCG::SetUseTwoNorm',
-  'HypreGMRES::GetTol', 'HypreGMRES::GetAbsTol', 'HypreGMRES::GetMaxIter',
-  'HypreGMRES::GetKDim', 'HypreFGMRES::GetTol', 'HypreFGMRES::GetMaxIter',
-  'HypreFGMRES::GetKDim', and 'HypreBoomerAMG::GetMaxIter'.
-
 GPU computing
 -------------
- Added the 'gpu', 'raja-gpu', and 'ceed-gpu' backend aliases/shortcuts which
-  automatically select between CUDA or HIP.
-
- 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)'.
-
- 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 the finite element
-  space to be nonconforming.
+- 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.

- 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 BCs. A new method,
-  SetSubVectorHost, has been added for cases where host execution is always
-  needed (e.g. when the DOFs array is small).
-
- Added GPU support in GradientGridFunction and InnerProduct Coefficient classes
-  by implementing their Project methods.
-
+- 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.
-
- 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 GPU support in GradientGridFunctionCoefficient and
+  InnerProductCoefficient by implementing their Project methods.

 New and updated examples and miniapps
 -------------------------------------
- Added the miniapps/fluids directory and moved the previous Navier and the new
-  incompressible Schrödinger flow miniapps into it.
-
- Introduced the new Incompressible Schrödinger Flow (ISF) miniapp, which models
-  inviscid fluid dynamics by solving the linear Schrödinger equation, leveraging
-  the hydrodynamical analogy to quantum mechanics.
-
- New particle-related miniapps:
-  * New transient Navier-Stokes fluid-particles solver NavierParticles in
-    miniapps/fluids/navier/navier_particles, for modeling tracer particles in
-    fluid flow, demonstrating use of the new ParticleSet class.
-  * New Navier miniapp, miniapps/fluids/navier/navier_bifurcation, showing the
-    use of NavierParticles in a 2D bifurcating channel flow.
-  * New FindPointsGSLIB miniapp, miniapps/gslib/particles_redist, showing
-    parallel-redistribution of particle data between MPI ranks.
-  * Particle visualization features in common/particles_extras for viewing
-    particle locations and trajectories (ParticleTrajectories) using GLVis.
+- 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

-
- Updated the mtop miniapp with a GPU enabled forward and adjoint solver for
-  isotropic linear elasticity.
-
-Miscellaneous
-------------
- Introduced MFEM_FETCH_TPLS CMake option to enable downloading, configuring,
-  and building of TPLs alongside MFEM (currently supported TPLs are hypre,
-  METIS, and GSLIB).
-
- Added quadrature function support to the VisIt and Conduit data collections.
-
- Added access to the internal parallel matrix in Par(Mixed)BilinearForm and
-  related utility methods for elimination of BCs.
-
- FindPointsGSLIB has a new constructor that accepts the mesh object and
-  internally calls the Setup() method so users do not have to. The FreeData()
-  method has also been moved to the destructor so users do not need to manually
-  free-up the memory if the destructor is called before MPI_Finalize().
-
- Added parallel Address Sanitizer, serial and parallel Undefined Behavior
-  Sanitizer and serial Memory Sanitizer GitHub actions tests on Ubuntu.
-
-API changes
