-Version 4.3.1 (development)
+Version 4.1.1 (development)
 ===========================
-- Added support for hr-adaptivity using TMOP-based error estimator.
-
-- Adding lowest order Nedelec and Raviart-Thomas basis functions on wedge
-  shaped elements.
-
-- Added initial support for meshes with pyramidal elements, including several
-  pyramidal meshes in the data/ directory and support for the lowest order H1,
-  Nedelec, Raviart-Thomas, and L2 basis functions on pyramids.
-
-- Updated the hypre interface according to changes in hypre-2.22.1. The ADS
-  solver is now fully working on GPUs.
-
-- Tetrahedral meshes no longer need to be reordered to support high order
-  Nedelec basis functions. This will allow future support for Nedelec basis
-  functions on wedges and pyramids which are not amenable to reordering. The
-  ReorientTetMesh method of the Mesh and ParMesh classes has been deprecated.
-
-
-Version 4.3, released on July 29, 2021
-======================================
-
-Discretization improvements
----------------------------
-- Variable order spaces, p- and hp-refinement. This is the initial (serial)
-  support for variable-order FiniteElementCollection and FiniteElementSpace.
-  The new method FiniteElementSpace::SetElementOrder can be called to set an
-  arbitrary order for each mesh element. The conforming interpolation matrix
-  will now automatically constrain p- and hp- interfaces, enabling general
-  hp-refinement in both 2D and 3D, on uniform or mixed NC meshes. Support for
-  parallel variable-order spaces will follow shortly.
-
-- Extended the support for field transfer between high-order and low-order
-  refined finite element spaces to include: dual fields and H1 fields (both
-  primary and dual). These are illustrated in the lor-transfer miniapp.
-
-- Improved libCEED integration, including support for VectorCoefficient,
-  ConvectionIntegrator, and VectorConvectionNLFIntegrator with libCEED backends.
-
-- Extending support for L2 basis functions using MapTypes VALUE and INTEGRAL in
-  linear interpolators and GridFunction "GetValue" methods.
-
-- Changed the interface for the error estimator and implemented the Kelly error
-  indicator for scalar-valued problems, supported in serial and parallel builds.
-
-- Added support for the "BR2" discontinuous Galerkin discretization for
-  diffusion via DGDiffusionBR2Integrator (see Example 14/14p).
-
-- Added convective and skew-symmetric integrators for the nonlinear term in the
-  Navier-Stokes equations.
-
-- Added new classes DenseSymmetricMatrix and SymmetricMatrixCoefficient for
-  efficient evaluation of symmetric matrix coefficients. This replaces the now
-  deprecated EvalSymmetric in MatrixCoefficient. Added DiagonalMatrixCoefficient
-  for clarity, which is a typedef of VectorCoefficient.
-
-- Added support for nonscalar coefficient with VectorDiffusionIntegrator.
-
-Linear and nonlinear solvers
-----------------------------
-- Added support for AMG preconditioners on GPUs based on the hypre library
-  (version 2.22.0 or later). These include BoomerAMG, AMS and ADS and most
-  MFEM examples that use hypre have been ported to support this functionality.
-  The GPU preconditioners require that both hypre and MFEM are built with CUDA
-  support. Hypre builds with CUDA and unified memory are also supported and
-  can be used with `-d cuda:uvm` as a command-line option.
-
-- Added support for AMG preconditioners for non-symmetric systems (e.g.
-  advection-dominated problems) using hypre's approximate ideal restriction
-  (AIR) AMG. Requires hypre version 2.14.0 or newer. Usage is illustrated in
-  example 9/9p.
-
-- Added new functionality for constructing low-order refined discretizations and
-  solvers, see the LORDiscretization and LORSolver classes. A new basis type for
-  H(curl) and H(div) spaces is introduced to give spectral equivalence. This
-  functionality is illustrated in the LOR solvers miniapp in miniapps/solvers.
-
-- Generalized the Multigrid class to support non-geometric multigrid. Previous
-  functionality, based on FiniteElementSpaceHierarchy, is now available in the
-  derived class GeometricMultigrid.
-
-- Introduced solver interface for linear problems with constraints, a few
-  concrete solvers that implement the interface, and a demonstration of their
-  use in Example 28(p), which solves an elasticity problem with zero normal
-  displacement (but allowed tangential displacement) on two boundaries.
-
-- Added high-order matrix-free auxiliary Maxwell solver for H(curl) problems,
-  as described in Barker and Kolev 2020 (https://doi.org/10.1002/nla.2348). See
-  Example 3p and linalg/auxiliary.?pp.
-
-- Improved interface for using the Ginkgo library, including: support for matrix-
-  free operators in Ginkgo solvers, new wrappers for Ginkgo preconditioners, HIP
-  support, and reduction of unnecessary data copies.
-
-- Added initial support for hypre's mixed integer (mixedint) capability, which
-  uses different data types for local and global indices in order to save memory
-  in large problems. This capability requires that hypre was configured with the
-  --enable-mixedint option. Note that this option is currently tested only in
-  ex1p, ex3p, and ex4p, and may not work in more general settings.
-
-- Added AlgebraicCeedSolver that does matrix-free algebraic p-multigrid for
-  diffusion problems with the Ceed backend.
-
-- Added interface to MUMPS direct solver. Its usage is demonstrated in ex25p.
-  See http://mumps.enseeiht.fr/ for more details. Supported versions >= 5.1.1.
-
-- Added three ESDIRK time integrators: implicit trapezoid rule, L-stable
-  ESDIRK-32, and A-stable ESDIRK-33.
-
-- Implemented a variable step-size IMEX (VSSIMEX) method for the Navier miniapp.
-
-- Implemented an adaptive linear solver tolerance option for NewtonSolver based
-  on the algorithm of Eisenstat and Walker.
-
-Meshing improvements
---------------------
-- Added support for reading high-order Lagrange meshes in VTK format. Arbitrary-
-  orders and all element types are supported. See the VTK blog for more info:
-  https://blog.kitware.com/wp-content/uploads/2018/09/Source_Issue_43.pdf.
-
-- Introduced a new non-conforming mesh format that fixes known inconsistencies
-  of legacy "MFEM mesh v1.1" NC format and works consistently in both serial and
-  parallel. ParMesh::ParPrint can now print non-conforming AMR meshes that can
-  be used to restart a parallel AMR computation. Example 6p has been extended to
-  demonstrate restarting from a previously saved checkpoint. Note that parallel
-  NC data files are compatible with serial code, e.g., can be viewed with serial
-  GLVis. Loading of legacy NC mesh files is still supported.
-
-- Added FMS support (https://github.com/CEED/FMS) to mfem. FMS can represent
-  unstructured high-order meshes with general high-order finite element fields
-  on them. When enabled, mfem can convert data collections to/from FMS data
-  collections in memory. In addition, an FMS data collection class was added so
-  the convert-dc miniapp can read and generate data files in FMS format.
-
-- Added new mesh quality metrics and improved the untangling capabilities of the
-  TMOP-based mesh optimization algorithms.
-
-- The TMOP mesh optimization algorithms were extended to GPU:
-  * QualityMetric 1, 2, 7, 77 are available in 2D, 302, 303, 315, 321 in 3D
-  * Both AnalyticAdaptTC and DiscreteAdaptTC TargetConstructor are available
-  * Kernels for normalization and limiting have been added
-  * The AdvectorCG now also supports AssemblyLevel::PARTIAL
-
-- Added support for creating refined meshes for all element types (e.g. by
-  splitting high-order elements into low-order refined elements), including
-  mixed meshes. The LOR Transfer miniapp (miniapps/tools/lor-transfer.cpp) now
-  supports meshes with any element geometry.
-
-- Meshes consisting of any type of elements (including mixed meshes) can be
-  converted to all-simplex meshes using Mesh::MakeSimplicial.
-
-- Several of the mesh constructors (creating Cartesian meshes, refined (LOR)
-  meshes, simplex meshes, etc.) are now available as "named constructors", e.g.
-  Mesh::MakeCartesian2D or Mesh::MakeRefined. The legacy constructors are marked
-  as deprecated.
-
-- Added support for creating periodic meshes with Mesh::MakePeriodic. The
-  requisite periodic vertex mappings can be created with
-  Mesh::CreatePeriodicVertexMapping.
-
-- Added support for 1D non-conforming meshes (which can be useful for parallel
-  load balancing and derefinement).
-
-- Added sample meshes in the `data` subdirectory showing the reference elements
-  of the six currently supported element types; ref-segment.mesh,
-  ref-triangle.mesh, ref-square.mesh, ref-tetrahedron.mesh, ref-cube.mesh, and
-  ref-prism.mesh.
-
-High-performance computing
---------------------------
-- Added initial support for GPU-accelerated versions of PETSc that works with
-  MFEM_USE_CUDA if PETSc has been configured with CUDA support. Examples 1 and 9
-  in the examples/petsc directory have been modified to work with --device cuda.
-  Examples with GAMG (ex1p) and SLEPc (ex11p) are also provided.
-
-- Added support for explicit vectorization in the high-performance templated
-  code for Fujitsu's A64FX ARM microprocessor architecture.
-
-- Added support for different modes of QuadratureInterpolator on GPU.
-  The layout (QVectorLayout::byNODES|byVDIM) and the tensor products modes can
-  be enabled before calling the Mult, Values, Derivatives, PhysDerivatives and
-  Determinants methods.
-
-- Added method Device::SetMemoryTypes that can be used to change the default
-  host and device MemoryTypes before Device setup.
-
-- In class MemoryManager, added methods GetDualMemoryType and SetDualMemoryType;
-  dual MemoryTypes are used to determine the second MemoryType (host or device)
-  when only one MemoryType is specified in methods of class Memory.
-
-- Added Memory constructor for setting both the host and device MemoryTypes.
-
-- Switched the default behavior of device memory allocations so that they are
-  deferred until the device pointer is needed.
-
-- Added a second Umpire device MemoryType, DEVICE_UMPIRE_2, with corresponding
-  allocator that can be set with the method SetUmpireDevice2AllocatorName.
-
-- Added HOST_PINNED MemoryType and a pinned host allocator for CUDA and HIP.
-
-- Added matrix-free GPU-enabled implementations of GradientInterpolator and
-  IdentityInterpolator.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new, very simple example (ex0 and parallel version ex0p). This example
-  solves a simple Poisson problem using H1 elements (the same problem as ex1),
-  but is intended to be extremely simple and approachable for new users.
-
-- Added new miniapps demonstrating: 1) the use of GSLIB for overlapping grids,
-  see gslib/schwarz_ex1, and 2) coupling different physics in different domains,
-  see navier/cht. Note that gslib v1.0.7 is require (see INSTALL for details).
-
-- Added a new miniapp for computing (signed) distance functions to a point
-  source or zero level set. See miniapps/shifted/distance.cpp.
-
-- Added a high-order extension of the shifted boundary method to solve PDEs on
-  non body-fitted meshes. This is illustrated in the new Shifted Diffusion
-  miniapp, see miniapps/shifted/diffusion.cpp.
-
-- Added new miniapp directory mtop/ with optimization-oriented block parametric
-  non-linear form and abstract integrators. Two new miniapps, ParHeat and
-  SeqHeat, demonstrate parallel and sequential implementation of gradients
-  evaluation for linear diffusion with discrete density.
-
-- Added a new miniapp block-solvers that compares the performance of various
-  solvers for mixed finite element discretization of the second order scalar
-  elliptic equations. Currently available solvers in the miniapp include a
-  block-diagonal preconditioner that is based on approximate Schur complement
-  (implemented in ex5p), and a newly implemented solver DivFreeSolver, which
-  exploits a multilevel decomposition of the Raviart-Thomas space and its
-  divergence-free subspace. See the miniapps/solvers directory for more details.
-
-- Introduced new options for the mesh-explorer miniapp to visualize the actual
-  element attributes in parallel meshes while retaining the visualization of the
-  domain decomposition.
-
-- Added partial assembly and device support to Example 25/25p, with diagonal
-  preconditioning.
-
-- Implemented a filter method for the Navier miniapp to stabilize highly
-  turbulent flows in direct numerical simulation.
-
-Improved testing
-----------------
-- Transitioned from Travis to GitHub Action for testing/CI on GitHub.
-
-- Use Spack (and Uberenv) to automate TPL building in LLNL GitLab tests.
-
-- Extended `make test` to include GPU tests when MFEM is built with CUDA or HIP
-  support.
-
-- Added a set of suggested git hooks for developers in config/githooks.
-
-- Added support for Caliper: a library to integrate performance profiling
-  capabilities into applications. See examples/caliper for more details.
-
-- Added a new command line boolean option (`--all`) to the unit tests to launch
-  *all* non-regression tests.
-
-- Upgraded the Catch unit test framework from version 2.13.0 to version 2.13.2.
-

-  help identify elements with poor mesh quality.
-
-- Added support for reading VTK meshes in XML format.
-
-- Added makefile rule to generate TAGS table for vi or Emacs users.
-

-
-- Various other simplifications, extensions, and bugfixes in the code.
-
-API changes
------------
-- Added an abstract interface `mfem::FaceRestriction` for `H1FaceRestriction`
-  and `L2FaceRestriction`.
-  In order to conform with the semantic of `MultTranspose` in `mfem::Operator`,
-  `mfem::FaceRestriction::MultTranspose` now sets instead of adding values, and
-  `mfem::FaceRestriction::AddMultTranspose` should replace previous calls to
-  `mfem::FaceRestriction::MultTranspose`.
-
-
-Version 4.2, released on October 30, 2020
-=========================================
-
-High-performance computing
---------------------------
-- Added support for explicit vectorization in the high-performance templated
-  code, which can now take advantage of specific classes on the following
-  architectures:
-  * x86 (SSE/AVX/AVX2/AVX512),
-  * Power8 & Power9 (VSX),
-  * BG/Q (QPX).
-  These are disabled by default, but can be enabled with MFEM_USE_SIMD=YES.
-  See the new file linalg/simd.hpp and the new directory linalg/simd.
-
-- Added an Element Assembly mode compatible with GPU device execution for H1 and
-  L2 spaces in the mass, convection, diffusion, transpose, and the face DG trace
-  integrators. See option '-ea' in Example 9. When enabled, this assembly level
-  stores independent dense matrices for the elements, and independent dense
-  matrices for the faces in the DG case.
-
-- Added a Full Assembly mode compatible with GPU device execution. This assembly
-  level builds on top of the Element Assembly kernels to compute a global sparse
-  matrix. All integrators supported by element assembly are also supported by
-  full assembly. See the '-fa' option in Example 9.
-
-- Optimized the AMD/HIP kernel support and enabled HIP support in the libCEED
-  integration. This is now available via the "ceed-hip" device backend.
-
-- Improved the libCEED integration to support:
-  * AssemblyLevel::NONE for Mass, Diffusion, VectorMass, and VectorDiffusion
-    Integrators. This level computes the full operator evaluation "on the fly".
-  * VectorMassIntegrator and VectorDiffusionIntegrator.
-  * All types of (scalar) Coefficients.
-
-- Added partial assembly / device support for:
-  * H(div) bilinear forms and VectorFEDivergenceIntegrator.
-  * BlockOperator, see the updated Example 5.
-  * Complex operators, see the updated Example 22.
-  * Chebyshev accelerated polynomial smoother.
-  * Convergent diagonal preconditioning on non-conforming adaptively refined
-    meshes, see Example 6/6p.
-
-- Added CUDA support for:
-  * Sparse matrix-vector multiplication with cuSPARSE,
-  * SUNDIALS ODE integrators, see updated SUNDIALS modification of Example 9/9p.
-
-Linear and nonlinear solvers
-----------------------------
-- Added a new solver class for simple integration with NVIDIA's multigrid
-  library, AmgX. The AmgX class is designed to work as a standalone solver or
-  preconditioner for existing MFEM solvers. It uses MFEM's sparse matrix format
-  for serial runs and the HypreParMatrix format for parallel runs. The new
-  solver may be configured to run with one GPU per MPI rank or with more MPI
-  ranks than GPUs. In the latter case, matrices and vectors are consolidated to
-  ranks communicating with the GPUs and the solution is then broadcasted.
-
-  Although CUDA is required to build, the AmgX support is compatible with the
-  MFEM CPU device configuration. The examples/amgx folder illustrates how to
-  integrate AmgX in existing MFEM applications. The AmgX solver class is
-  partially based on: "AmgXWrapper: An interface between PETSc and the NVIDIA
-  AmgX library", by Pi-Yueh Chuang and Lorena A. Barba, doi:10.21105/joss.00280.
-
-- Added initial support for geometric h- and p-multigrid preconditioners for
-  matrix-based and matrix-free discretizations with basic GPU capability, see
-  Example 26/26p.
-
-- Added support for the CVODES package in SUNDIALS which provides ODE solvers
-  with sensitivity analysis capabilities. See the CVODESSolver class and the new
-  adjoint miniapps in the miniapps/adjoint directory.
-
-- Added an interface to the MKL CPardiso solver, an MPI-parallel sparse direct
-  solver developed by Intel. See Example 11p for an illustration of its usage.
-
-- Added support for the SLEPc eigensolver package, https://slepc.upv.es.
-
-- Upgraded SuperLU interface to use SuperLU_DIST 6.3.1. Added a simple SuperLU
-  example in the new directory examples/superlu.
-
-- Extended the KINSOL (SUNDIALS) nonlinear solver interface to support the
-  Jacobian-free Newton-Krylov method. A usage example is shown in Example 10p.
-
-- Block arrays of parallel matrices can now be merged into a single parallel
-  matrix with the function HypreParMatrixFromBlocks. This could be useful for
-  solving block systems with parallel direct solvers such as STRUMPACK.
-
-- Added wrappers for hypre's flexible GMRES solver and the new parallel ILU
-  preconditioner. The latter requires hypre version 2.19.0 or later.
-
-Discretization improvements
----------------------------
-- Extended GSLIB-FindPoints integration to support simplices and interpolation
-  of functions from L2, H(div) and H(curl) spaces.
-
-- Added support for computing asymptotic error estimates and convergence rates
-  for the whole de Rham sequence based on the new class ConvergenceStudy and new
-  member methods in GridFunction and ParGridFunction. See the rates.cpp file in
-  the tests/convergence directory for sample usage.
-
-- Extended the GetValue and GetVectorValue methods of GridFunction to support
-  evaluation on boundary elements and, in the continuous field case, arbitrary
-  mesh edges and faces. This requires passing an ElementTransformation argument.
-
-- Added support for matrix-free interpolation and restriction operators between
-  continuous H1 finite element spaces of different order on the same mesh or
-  with the same order on uniformly refined meshes.
-
-- The Coefficient classes based on a C-function pointer (FunctionCoefficient,
-  VectorFunctionCoefficient and MatrixFunctionCoefficient) now use the more
-  general std::function class template. This allows the classes to be backward
-  compatible (i.e. they can still work with C-functions) and, in addition,
-  support any "callable", e.g. lambda functions.
-
-- Non-conforming meshes are now supported with block nonlinear forms. See the
-  updated Example 19/19p.
 
 Meshing improvements
 --------------------
 - The graph linear ordering library Gecko, previously an external dependency, is
   now included directly in MFEM. As a result, Mesh::GetGeckoElementOrdering is
   always available. The interface has also been improved, see for example the
-  Mesh Explorer miniapp.
+  mesh-explorer miniapp.
 
 - Added support for finite difference-based gradient and Hessian approximation
   in the TMOP mesh optimization algorithms. This improves the accuracy of the
   Hessian for r-adaptivity using discrete fields, and allows use of skewness
   and orientation based metrics.
 
-- Improved Gmsh reader (version 2.2), which now supports both high-order and
-  periodic meshes. Segments, triangles, quadrilaterals, and tetrahedra are
-  supported up to order 10. Wedges and hexahedra are supported up to order 9.
-  For sample periodic meshes, see the periodic*.msh files in the data directory.
-
-- Added support for construction of (serial) non-conforming meshes. Hanging
-  nodes can be marked with Mesh::AddVertexParents when building the mesh with
-  the "init" constructor. The usage is demonstrated in a new meshing miniapp,
-  Polar NC, which generates meshes that are non-conforming from the start.
-
 - 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.
+  the user to specify different discrete functions for controlling the
+  size, aspect-ratio, orientation, and skew of elements in the mesh.
 
-- Additional TMOP improvements:
-  * Capability for approximate tangential mesh relaxation.
-  * Support and examples for using TMOP on mixed meshes.
-  * Complete integrator action accounting for spatial derivatives of discrete
-    and analytic targets.
+- Added TMOP capability for approximate tangential mesh relaxation.
+

+  for example the periodic-annulus-sector and periodic-torus-sector files in
+  the data directory.
+
+- Added complete action of the TMOP Integrator to account for the spatial
+  derivatives of discrete and analytic targets.
+
+Performance improvements
+------------------------

+  code, which can now take advantage of specific intrinsics classes on the
+  following architectures:

+  See the new file linalg/simd.hpp and the new directory linalg/simd.
+
+Improved GPU capabilities
+-------------------------
+- Added support for Chebyshev accelerated polynomial smoother on GPU.
+
+- Optimized AMD/HIP kernel support.
+
+- 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 support for BlockOperator on GPU. See the updated Example 5.
+
+- Added partial assembly and GPU support for ComplexOperator,
+  [Par]ComplexGridFunction, [Par]ComplexLinearForm, and [Par]SesquilinearForm.
+  See the updated Example 22.
+
+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.
+
+- Added support face integrals on the boundaries of NURBS meshes.
+
+Linear and nonlinear solvers
+----------------------------
+- Added power method to iteratively estimate the largest eigenvalue and the
+  corresponding eigenvector of an operator.
+
+- Added initial support for h- and p-multigrid solvers and preconditioners for
+  matrix-based and matrix-free discretizations with basic GPU capability.
+
+- 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.
 
 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.

-This directory contains recommended git hooks, which are scripts that can be
-used to improve your development experience with MFEM:
-
-### The hooks
-
-* `pre-commit` is a hook that will be applied before each commit and run
-`astyle` on the code. This will ensure that your changes comply with the MFEM
-code styling guidelines.
-
-* `pre-push` is a hook that will be applied before each push to run a quick set
-of tests that verify that your files headers are in compliance, and that you did
-not add any large files to the repo.
-
-### Setup
-
-To setup the git hooks, run `make hooks`, which creates symlinks to the hooks in
-the `.git/hooks` directory. Individual hooks can be enabled by manually creating
-symlinks.
-
-(You may also copy the scripts directly and customize them further, but this way
-you may miss additional updates in the future.)
-
-### Failures

-The `branch-history` check can fail in some cases when the history is OK. For
-example, when a large number of files were modified for a legitimate reason, or
-when a picture was added for documentation.
-
-If that is the case, make sure the failure is indeed justified, and rerun the
-push command with the `--no-verify` option. This will skip the hooks, allowing
-you to push those changes.
