-This directory contains the GitHub CI scripts for MFEM.
-
-Note that some of these scripts use the shared MFEM GitHub Actions from the external mfem/github-actions repository:
-
-  https://github.com/mfem/github-actions
-
-For a particular action, e.g. `mfem/github-actions/build-mfem@v2.1`, the `v2.1` suffix denotes the branch in the above from which the action is taken.
-
-The current CI workflows are:
-
-### `repo-check.yml`
-
-Runs a number of static repository-level sanity checks.
-
-- `file-headers-check` checks copyright date, license, etc. using the `--copyright`, `--license` and `--release` options of the `config/githooks/pre-push` script.
-
-- `code-style` checks the code style using the `--style` option of the `config/githooks/pre-push` script.
-
-- `documentation` checks the documentation build using the `tests/scripts/documentation` script.
-
-- `branch-history` guards against accidental commits of large files using the `--history` option of the `config/githooks/pre-push` script.
-
-### `mfem-analysis.yml` (`build-analysis`)
-
-Checks if the code builds and satisfies minimal requirements.
-
-- `gitignore` builds hypre, METIS, and MFEM using `mfem/github-actions/build-hypre`, `mfem/github-actions/build-metis`, and `mfem/github-actions/build-mfem` and checks for correct `.gitignore` settings by running the `tests/scripts/gitignore` script.
-
-### `builds-and-tests.yml`
-
-Runs a matrix of builds and tests runs with different compilers, OS, mfem/hypre settings, etc. Also processes and upload Codecov reports.
-
-Uses the following GitHub Actions from https://github.com/mfem/github-actions:
-
-- `mfem/github-actions/build-hypre`
-- `mfem/github-actions/build-metis`
-- `mfem/github-actions/build-mfem`
-- `mfem/github-actions/upload-coverage`

-Version 4.4.1 (development)
+Version 4.3.1 (development)
 ===========================
 
-Meshing improvements
---------------------
-- Added support for mixed meshes and pyramids in GSLIB-FindPoints.
+- Add hipSPARSE support for sparse mat-vec multiplications.
 
-Discretization improvements
----------------------------
-- 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.
+- Added support for using the HYPRE library built with HIP support. Similar to
+  the HYPRE + CUDA support added earlier, most of the MFEM examples and miniapps
+  work transparently with HYPRE + HIP builds. This includes the BoomerAMG, AMS,
+  and ADS solvers.
 
-- 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 by MFEM capabilities, i.e. 2D serial meshes. All mixed
-  element topologies are supported in serial and parallel: segment, triangle,
-  square, tetrahedron, cube, prism, and pyramid.
-
-- 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))
-
-- 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.
-
-Linear and nonlinear solvers
-----------------------------
-
-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.
-
-- 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.
-
-- 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.
-
-- 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 example for body-fitted volumetric and shape integration using the
-  Algoim library.
-
-- Added Windows 2022 CI testing with GitHub actions.
-
-Miscellaneous
--------------
-- Various other simplifications, extensions, and bugfixes in the code.
-
-
-- Added boundary elimination with device support for `SparseMatrix` and
-  `HypreParMatrix`.
-  
-- When using `AssemblyLevel::FULL`, `FABilinearFormExtension::FormSystemMatrix`
-  outputs an `OperatorHandle` containing a `SparseMatrix` in serial, and an
-  `HypreParMatrix` in parallel (instead of a `ConstrainedOperator`).
-
-- Added TMOP metrics for mesh untangling and worst-case quality improvement.
-
-Version 4.4, released on March 21, 2022
-=======================================
-
-Linear and nonlinear solvers
-----------------------------
-- Added support for using the hypre library built with HIP support. Similar to
-  the existing hypre + CUDA support, most of the MFEM examples and miniapps work
-  transparently with hypre + HIP builds. This includes the BoomerAMG, AMS, and
-  ADS solvers.
-
-- Added a simple singleton class, Hypre, to automatically set hypre's global
-  parameters, particularly GPU-relevant options. Updated parallel example codes
-  and miniapps to call Hypre::Init() where appropriate.
-
-- Added hipSPARSE support for sparse matrix-vector multiplications.
-
-- More explicit and consistent formatting of the output of iterative solvers
+- More explicit and consistent formating of the output of iterative solvers
   with the new IterativeSolver::PrintLevel options. See linalg/solvers.hpp.
 
-Meshing improvements
---------------------
-- New TMOP-based methods for hr-adaptivity, interface fitting, and tangential
-  relaxation of high-order meshes.
+- Added a miniapp for PDE-based extrapolation of finite element functions. See
+  miniapps/shifted/extrapolate.cpp.
+
+- Added support for automatic differentiation. Users can select between native
+  implementation and external library implementation during configuration. One
+  parallel and two serial examples are implemented in the miniapps/autodiff/
+  directory.
+
+- GridFunctionCoefficient (and the related vector, gradient, divergence, and
+  curl classes) now work properly with LORDiscretization and LORSolver.
+
+- Added support for mesh preprocessing to resolve fine scale problem data
+  before simulation. This feature uses adaptive mesh refinement to control the
+  associated data oscillation error. See the new Example 30/30p.
+
+- Switched from Artistic Style (astyle) version 2.05.1 to version 3.1 for code
+  formatting. See the "make style" target.
+
+- Split the fem/fe.?pp files into separate files in the new fem/fe/ directory
+  to simplify and clarify the organization of FiniteElement classes.
+
+- Added support for hr-adaptivity using TMOP-based error estimator.
+
+- Coefficient::SetTime now propagates the new time into internally stored
+  Coefficient objects.
+
+- Added initial support for google-benchmarks in the tests/benchmarks directory.
+  It can be enabled with MFEM_USE_BENCHMARK=YES.
+
+- Added Binder (mybinder.org) configuration files for C++ MFEM Jupyter Notebooks
+  with inline GLVis visualization as well as a new examples/jupyter/ directory
+  with a sample notebook based on Example 1. Implementation based on xeus-cling,
+  github.com/jupyter-xeus/xeus-cling + xeus-glvis, github.com/GLVis/xeus-glvis.
+
+- Added 'double' atomicAdd implementation for previous versions of CUDA.
+
+- 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.
 
-- Added a simpler interface to access mesh face information, see FaceInformation
-  and GetFaceInformation in the Mesh class.
+- Updated the hypre interface according to changes in hypre-2.22.1. The ADS
+  solver is now fully working on GPUs.
 
-- Added the method ParMesh::GetSerialMesh() that reconstructs a partitioned
-  parallel mesh on a given single rank. Also, added the method
-  ParMesh::PrintAsSerial() that saves the reconstructed serial mesh to a C++
-  stream on rank 0.
+- 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.
 
-- Gmsh meshes where all elements have zero physical tag (the default Gmsh output
-  format if no physical groups are defined) are now successfully loaded, and
-  elements are reassigned attribute number 1.
+- Gmsh meshes where all elements have zero physical tag (the default Gmsh

-
-- Coefficient::SetTime now propagates the new time into internally stored
-  Coefficient objects.
-
-- Split the fem/fe.?pp files into separate files in the new fem/fe/ directory to

-New and updated examples and miniapps
--------------------------------------
-- Added two new miniapps with initial support for automatic differentiation (AD)
-  in the miniapps/autodiff/ directory. Users can select between external library
-  and native implementation during configuration. The support for AD will be
-  extended in future releases of MFEM.
-
-- Added Binder (mybinder.org) configuration files for C++ MFEM Jupyter Notebooks
-  with inline GLVis visualization in the new examples/jupyter/ directory with a
-  sample notebook based on Example 1. The implementation is based on xeus-cling,

-
-- Added a new miniapp (Extrapolation) for PDE-based extrapolation of finite
-  element functions from known values in a set of elements to the rest of the
-  computational domain. See miniapps/shifted/extrapolate.cpp.
-
-- Added new miniapp that uses the ParELAG library, its hybrid smoothers, and the
+- Added new miniapps that use the ParELAG library, its hybrid smoothers, and the
   hierarchy of spaces created by the element-based AMG (AMGe) methodology in
   ParELAG to build multigrid solvers for H(curl) and H(div) forms. See the
   miniapps/parelag directory for more details.
 
-- Added a new Example 30/30p demonstrating support for mesh preprocessing to
-  resolve fine scale problem data before simulation. This feature uses adaptive
-  mesh refinement to control the associated data oscillation error.
-
-- Added new Examples 31, 31p and 32p showing anisotropic definite Maxwell
-  serial/parallel solver and parallel eigensolver 1D, 2D, or 3D.
-
-- Updated the mesh-optimizer and pmesh-optimizer miniapps to demonstrate the
-  hr-adaptivity and interface fitting capability.
-
-- The HPC versions of ex1 and ex1p (in miniapps/performance) now support runtime
-  selection of either 2D or 3D meshes.
-
-Integrations, testing and documentation
----------------------------------------
-- Doxygen documentation for all releases is now available at docs.mfem.org.
-

-  Bake-Off Problems, see tests/benchmarks/bench_assembly_levels.cpp.
-
-Miscellaneous
--------------
-- Added a simple singleton class, Mpi, as a replacement for MPI_Session. New
-  code should use Mpi::Init() and other Mpi methods instead of MPI_Session.
-
-- Added ParaView visualization of QuadratureFunction fields, through both
-  QuadratureFunction::SaveVTU and ParaViewDataCollection::RegisterQField.
-
 - Fixed several MinGW build issues on Windows.
 
-- In various places in the library, replace the use of 'long' with 'long long'

-# 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
-
-Here is how to build the container. Note that we build so it belongs to the same
-namespace as the repository here. "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. From the root of the repository:
-
-```bash
-$ docker build -f config/docker/Dockerfile -t ghcr.io/mfem/mfem-ubuntu .
-$ docker build -f config/docker/Dockerfile.base -t ghcr.io/mfem/mfem-ubuntu-base .
-```
-
-### Shell Ubuntu
-
-To shell into the container:
-
-```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
-
-You can read more about interaction with these examples and miniapps below.
-
-### Shell Ubuntu Base
-
-To shell into the container:
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu-base bash
-```
-
-Off the bat, you can see mfem libraries are in your path so you can jump into development:
-
-```bash
-env | grep mfem
-```
-```bash
-PKG_CONFIG_PATH=/opt/mfem-env/.spack-env/view/lib/pkgconfig:/opt/mfem-env/.spack-env/view/share/pkgconfig:/opt/mfem-env/.spack-env/view/lib64/pkgconfig
-PWD=/opt/mfem-env
-MANPATH=/opt/mfem-env/.spack-env/view/share/man:/opt/mfem-env/.spack-env/view/man:
-CMAKE_PREFIX_PATH=/opt/mfem-env/.spack-env/view
-SPACK_ENV=/opt/mfem-env
-ACLOCAL_PATH=/opt/mfem-env/.spack-env/view/share/aclocal
-LD_LIBRARY_PATH=/opt/mfem-env/.spack-env/view/lib:/opt/mfem-env/.spack-env/view/lib64
-PATH=/opt/mfem-env/.spack-env/view/bin:/opt/view/bin:/opt/spack/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
-```
-
-#### Examples and MiniApps
-
-If you want to develop a tool that _uses_ mfem, you can find the built libraries in:
-
-```
-$ ls /opt/mfem-env/.spack-env/view/
-bin  etc  include  lib  libexec  sbin  share  var
-```
-
-And yes, this is the working directory when you shell into the container!
-You can find the examples here:
-
-
-```bash
-cd share/mfem/examples
-```
-```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
-```
-
-Try running a few, and look at the associated .cpp file for the source code!
-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!
-
-
-#### Your own App
-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:/src bash
-```
-
-In the above, we can pretend your project is in the present working directory (PWD) and we are
-binding to source. You can then use the mfem in the container for development, and if you
-want to distribute your library or app in a container, you can use the mfem container as the base.
