-Version 3.4.1 (development)
-===========================
- Added support for reading linear and quadratic 2D quadrilateral and triangular
-  Cubit meshes.
-
- The tetrahedral mesh refinement algorithm in serial and in parallel now
-  follows precisely the paper:
-     D. Arnold, A. Mukherjee, and L. Pouly, "Locally Adapted Tetrahedral Meshes
-     Using Bisection", SIAM J. Sci. Comput., 22(2), 431–448.
-  This guarantees that the shape regularity of the elements will be preserved
-  under refinement.
-
-
-Version 3.4, released on May 29, 2018
-=====================================
-
-More general and efficient mesh adaptivity
------------------------------------------
- Added support for PUMI, the Parallel Unstructured Mesh Infrastructure from
-  https://scorec.rpi.edu/pumi. PUMI is an unstructured, distributed mesh data
-  management system that is capable of handling general non-manifold models and
-  effectively supports automated adaptive analysis. PUMI enables for the first
-  time support for parallel unstructured modifications of MFEM meshes.
-
- Significantly reduced MPI communication in the construction of the parallel
-  prolongation matrix in ParFiniteElementSpace, for much improved parallel
-  scaling of non-conforming AMR on hundreds of thousands of MPI tasks. The
-  memory footprint of the ParNCMesh class has also been reduced.
-
- In FiniteElementSpace, the fully assembled refinement matrix is now replaced
-  by default by a specialized refinement operator. The operator option is both
-  faster and more memory efficient than using the fully assembled matrix. The
-  old approach is still available and can be enabled, if needed, using the new
-  method FiniteElementSpace::SetUpdateOperatorType().
-
-Discretization improvements
---------------------------
- Added support for a general "high-order"-to-"low-order refined" transfer of
-  GridFunction and true-dof data from a "high-order" finite element space
-  defined on a coarse mesh, to a "low-order refined" space defined on a refined
-  mesh. The new methods, GetTransferOperator and GetTrueTransferOperator in the
-  FiniteElementSpace classes, work in both serial and parallel and support
-  matrix-based as well as matrix-free transfer operator representations. They
-  use a new method, GetTransferMatrix, in the FiniteElement class similar to
-  GetLocalInterpolation, that allows the coarse FiniteElement to be different
-  from the fine FiniteElement.
-
- Added class ComplexOperator, that implements the action of a complex operator
-  through the equivalent 2x2 real formulation. Both symmetric and antisymmetric
-  block structures are supported.
-
- Added classes for general block nonlinear finite element operators (deriving
-  from BlockNonlinearForm and ParBlockNonlinearForm) enabling solution of
-  nonlinear systems with multiple unknowns in different function spaces. Such
-  operators have assemble-based action and also support assembly of the gradient
-  operator to enable inversion with Newton iteration.
-
- Added variable order NURBS: for each space each knot vector in the mesh can
-  have a different order. The order information is now part of the finite
-  element space header in the NURBS mesh output, so NURBS meshes in the old
-  format need to be updated.
-
- In the classes NonlinearForm and ParNonlinearForm, added support for
-  non-conforming AMR meshes; see also the "API changes" section.
-
- New specialized time integrators: symplectic integrators of orders 1-4 for
-  systems of first order ODEs derived from a Hamiltonian and generalized-alpha
-  ODE solver for the filtered Navier–Stokes equations with stabilization. See
-  classes SIASolver and GeneralizedAlphaSolver in linalg/ode.hpp.
-
- Inherit finite element classes from the new base class TensorBasisElement,
-  whenever the basis can be represented by a tensor product of 1D bases.
-
- Added support for elimination of boundary conditions in block matrices.
-
-New and updated examples and miniapps
-------------------------------------
- Added a new serial and parallel example (ex19) that solves the quasi-static
-  incompressible hyperelastic equations. The example demonstrates the use of
-  block nonlinear forms as well as custom block preconditioners.
-
- Added a new electromagnetics miniapp, Maxwell, for simulating time-domain
-  electromagnetics phenomena as a coupled first order system of equations.
-
- A simple local refinement option has been added to the mesh-explorer miniapp
-  (menu option 'r', sub-option 'l') that selects elements for refinement based
-  on their spatial location - see the function 'region()' in the source file.
-
- Added a set of miniapps specifically focused on Isogeometric Analysis (IGA) on
-  NURBS meshes in the miniapps/nurbs directory. Currently the directory contains
-  variable order NURBS versions of examples 1, 1p and 11p.
-
- Added PUMI versions of examples ex1, ex1p, ex2 and ex6p in a new examples/pumi
-  directory. The new examples demonstrate the PUMI APIs for parallel and serial
-  mesh loading (ex1 and ex1p), applying BCs using classification (ex2), and
-  performing parallel mesh adaptation (ex6p).
-
- Added two new miniapps related to DataCollection I/O in miniapps/tools:
-  load-dc.cpp can be used to visualize fields saved via DataCollection classes;
-  convert-dc.cpp demonstrates how to convert between MFEM's different concrete
-  DataCollection options.
-
- Example 10p with its SUNDIALS and PETSc versions have been updated to reflect
-  the change in the behavior of the method ParNonlinearForm::GetLocalGradient()
-  (see the "API changes" section) and now works correctly on non-conforming AMR
-  meshes. Example 10 and its SUNDIALS version have also been updated to support
-  non-conforming ARM meshes.
-
-Miscellaneous
-------------
- Documented project workflow and provided contribution guidelines in the new
-  top-level file, CONTRIBUTING.md.
-
- Added (optional) Conduit Mesh Blueprint support of MFEM data for both in-core
-  and I/O use cases. This includes a new ConduitDataCollection that provides
-  json, simple binary, and HDF5-based I/O. Support requires Conduit >= v0.3.1
-  and VisIt >= v2.13.1 will read the new Data Collection outputs.
-
- Added a new developer tool, config/sample-runs.sh, that extracts the sample
-  runs from all examples and miniapps and runs them. Optionally, it can save the
-  output from the execution to files, allowing comparison between different
-  versions and builds of the library.
-
- Support for building a shared version of the MFEM library with GNU make.
-
- Added a build option, MFEM_USE_EXCEPTIONS=YES, to throw an exception instead
-  of calling abort on mfem errors.
-
- When building with the GnuTLS library, switch to using X.509 certificates for
-  secure socket authentication. Support for the previously used OpenPGP keys has
-  been deprecated in GnuTLS 3.5.x and removed in 3.6.0. For secure communication
-  with the visualization tool GLVis, a new set of certificates can be generated
-  using the latest version of the script 'glvis-keygen.sh' from GLVis.
-
- Upgraded MFEM to support Axom 0.2.8. Prior versions are no longer supported.
-
-API changes
-----------
- Introduced a new enum, Matrix::DiagonalPolicy, that replaces the integer
-  parameters in many methods that perform elimination of rows and/or columns in
-  matrices. Some examples of such methods are:
-  * class SparseMatrix: EliminateRow(), EliminateCol(), EliminateRowCol(), ...
-  * class BilinearForm: EliminateEssentialBC(), EliminateVDofs(), ...
-  * class StaticCondensation: EliminateReducedTrueDofs()
-  * class BlockMatrix: EliminateRowCol()
-  Calling these methods with an explicitly given (integer) constants, will now
-  generate compilation errors, please use one of the new enum constants instead.
-
- Modified the virtual method AbstractSparseMatrix::EliminateZeroRows() and its
-  implementations in derived classes, to accept an optional 'threshold'
-  parameter, replacing previously hard-coded threshold values.
-
- In the classes NonlinearForm and ParNonlinearForm:
-  * The method GetLocalGradient() no longer imposes boundary conditions. The
-    motivation for the change is that, in the case of non-conforming AMR,
-    performing the elimination at the local level is incorrect - it must be
-    applied at the true-dof level.
-  * The method SetEssentialVDofs() is now deprecated.
-
-
-Version 3.3.2, released on Nov 10, 2017
+Development version 3.3.1, not released
 =======================================

-High-order mesh optimization
----------------------------
- Added support for mesh optimization via node-movement based on the Target-
-  Matrix Optimization Paradigm (TMOP) developed by P.Knupp et al. A variety of
-  mesh quality metrics, with their first and second derivatives have been
-  implemented. The combination of targets & quality metrics is used to optimize
-  the physical node positions, i.e., they must be as close as possible to the
-  shape, size and/or alignment of their targets. The optimization of arbitrary
-  high-order meshes in 2D, 3D, serial and parallel is supported.
-
- The new Mesh Optimizer miniapp can be used to perform mesh optimization with
-  TMOP in serial and parallel versions. The miniapp also demonstrates the use of
-  nonlinear operators and their coupling to Newton methods for solving
-  minimization problems.
-
 New and improved solvers and preconditioners
 --------------------------------------------
- MFEM is now included in the xSDK project, the Extreme-scale Scientific
-  Software Development Kit, as of xSDK-0.3.0. Various changes were made to
-  comply with xSDK's community policies, https://xsdk.info/policies, including:
-  xSDK-specific options in CMake, support for user-provided MPI communicators,
-  runtime API for version number, and the ability to disable/redirect output.
-  For more details, see general/globals.hpp and in particular the mfem::err and
-  mfem::out streams replacing std::err and std::out respectively.
-
- Added (optional) support for the STRUMPACK parallel sparse direct solver and
+- Added optional support for the STRUMPACK parallel sparse direct solver and
  preconditioner. STRUMPACK uses Hierarchically Semi-Separable (HSS) compression
  in a fully algebraic manner, with interface similar to SuperLU_DIST. See

-
- Updated MFEM integration to support the new SUNDIALS 3.0.0 interface.
+Performance improvements
+------------------------
+- Memory optimizations in the NCMesh class, which now uses 50% less memory.
+  The average cost of an NC element in a uniformly refined mesh (including the
+  refinement hierarchy, but excluding the temporary face_list and edge_list)
+  is now only about 290 bytes. This also makes the class faster.

 New and updated examples and miniapps
 -------------------------------------
- Added a new serial and parallel example (ex18) that solves the transient Euler
-  equations on a periodic domain with explicit time integrators. In the process
-  extended the NonlinearForm class to allow for integrals over faces and
-  exchanging face-neighbor data in parallel.
-
 - Added a new meshing miniapp, Shaper, that can be used to resolve complicated
  material interfaces by mesh refinement, e.g. as a tool for initial mesh
  generation from prescribed "material()" function.  Both conforming and
  non-conforming (isotropic and anisotropic) refinements are supported.

- Added a new meshing miniapp, Mesh Optimizer, that demonstrates the use of TMOP
-  for mesh optimization (serial and parallel version.)
-
 - Added SUNDIALS version of Example 16/16p.

 Discretization improvements
 ---------------------------
+- Added the ability to integrate delta functions on the righ-hand side (by
+  sampling the test function at the center of the delta coefficient). Currently
+  this is supported in the DomainLFIntegrator, VectorDomainLFIntegrator and
+  VectorFEDomainLFIntegrator classes.
+
 - Added a FindPoints method of the Mesh and ParMesh classes that returns the
  elements that contain a given set of points, together with the coordinates of
  the points in the reference space of the corresponding element.  In parallel,
  if a point is shared by multiple processors, only one of them will mark that
  point as found. Note that the current implementation of this method is not
-  optimal and/or 100% reliable. See the mesh-explorer miniapp for an example.
-
- Added a new class InverseElementTransformation, that supports a number of
-  algorithms for inversion of general ElementTransformations. This class can be
-  used as a more flexible and extensible alternative to ElementTransformation's
-  TransformBack method. It is also used in the FindPoints methods as a tunable
-  and customizable inversion algorithm.
-
- Memory optimizations in the NCMesh class, which now uses 50% less memory than
-  before. The average cost of an element in a uniformly refined mesh (including

-  VectorFEDomainLFIntegrator classes.
-
- Added five new linear interpolators in fem/bilininteg.cpp to compute products

-
- Added matrix coefficient support to CurlCurlIntegrator.
-
- Extend the method NodalFiniteElement::Project for VectorCoefficient to work
-  with arbitrary number of vector components.

 Miscellaneous
 -------------
- Added a .gitignore file that ignores all files erased by "make distclean",
-  i.e. the files that can be generated from the source but we don't want to
-  track in the repository, as well as a few platform-specific files.
-
- Added Linux, Mac and Windows CI testing on GitHub with Travis CI and Appveyor.
-
- Added a new macro, MFEM_VERSION, defined as a single integer of the form
-  (major*100 + minor)*100 + patch. The convention is that an even number
-  (i.e. even patch number) denotes a "release" version, while an odd number
-  denotes a "development" version. See config/config.hpp.in.
-
- Added an option for building in parallel without a METIS dependency. This is
-  used for example the Laghos miniapp, https://github.com/CEED/Laghos.
-
 - Modified the installation layout: all headers, except the master headers
  (mfem.hpp and mfem-performance.hpp), are installed in <PREFIX>/include/mfem;
  the master headers are installed in both <PREFIX>/include/mfem and in
  <PREFIX>/include. The mfem configuration and testing makefiles (config.mk and
  test.mk) are installed in <PREFIX>/share/mfem, instead of <PREFIX>.

-### Code Overview
-
- The MFEM library uses object-orient design principles which reflect, in code,
-  the independent mathematical concepts of meshing, linear algebra and finite
-  element spaces and operators.
-
- The MFEM source code has the following structure:
-  ```
-  .
-  ├── config
-  │   └── cmake
-  │       └── modules
-  ├── data
-  ├── doc
-  │   └── web
-  │       └── examples
-  ├── examples
-  │   ├── petsc
-  │   ├── pumi
-  │   └── sundials
-  ├── fem
-  ├── general
-  ├── linalg
-  ├── mesh
-  └── miniapps
-      ├── common
-      ├── electromagnetics
-      ├── meshing
-      ├── nurbs
-      ├── performance
-      └── tools
-  ```
-
- The main directories are `fem/`, `mesh/` and `linalg/` containing the C++
-  classes implementing the finite element, mesh and linear algebra concepts
-  respectively.
-
- The main mesh classes are:
-  + [`Mesh`](http://mfem.github.io/doxygen/html/classmfem_1_1Mesh.html)
-  + [`NCMesh`](http://mfem.github.io/doxygen/html/classmfem_1_1NCMesh.html)
-  + [`Element`](http://mfem.github.io/doxygen/html/classmfem_1_1Element.html)
-  + [`ElementTransformation`](http://mfem.github.io/doxygen/html/classmfem_1_1ElementTransformation.html)
-
- The main finite element classes are:
-  + [`FiniteElement`](http://mfem.github.io/doxygen/html/classmfem_1_1FiniteElement.html)
-  + [`FiniteElementCollection`](http://mfem.github.io/doxygen/html/classmfem_1_1FiniteElement.html)
-  + [`FiniteElementSpace`](http://mfem.github.io/doxygen/html/classmfem_1_1FiniteElementSpace.html)
-  + [`GridFunction`](http://mfem.github.io/doxygen/html/classmfem_1_1GridFunction.html)
-  + [`BilinearFormIntegrator`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearFormIntegrator.html) and [`LinearFormIntegrator`](http://mfem.github.io/doxygen/html/classmfem_1_1LinearFormIntegrator.html)
-  + [`LinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1LinearFormIntegrator.html), [`BilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearForm.html) and [`MixedBilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1MixedBilinearForm.html)
-
- The main linear algebra classes and sources are
-  + [`Operator`](http://mfem.github.io/doxygen/html/classmfem_1_1Operator.html) and [`BilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearForm.html)
-  + [`Vector`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearForm.html) and [`LinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1LinearForm.html)
-  + [`DenseMatrix`](http://mfem.github.io/doxygen/html/classmfem_1_1DenseMatrix.html) and [`SparseMatrix`](http://mfem.github.io/doxygen/html/classmfem_1_1SparseMatrix.html)
-  + Sparse [smoothers](http://mfem.github.io/doxygen/html/sparsesmoothers_8hpp.html) and linear [solvers](http://mfem.github.io/doxygen/html/solvers_8hpp.html)
-
- Parallel MPI objects in MFEM inherit their serial counterparts, so a parallel
-  mesh for example is just a serial mesh on each task plus the information on
-  shared geometric entities between different tasks. The parallel source files
-  have a `p` prefix, e.g. `pmesh.cpp` vs. the serial `mesh.cpp`.
-
- The main parallel classes are
-  + [`ParMesh`](http://mfem.github.io/doxygen/html/solvers_8hpp.html)
-  + [`ParNCMesh`](http://mfem.github.io/doxygen/html/classmfem_1_1ParMesh.html)
-  + [`ParFiniteElementSpace`](http://mfem.github.io/doxygen/html/classmfem_1_1ParFiniteElementSpace.html)
-  + [`ParGridFunction`](http://mfem.github.io/doxygen/html/classmfem_1_1ParGridFunction.html)
-  + [`ParBilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1ParBilinearForm.html) and [`ParLinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1ParLinearForm.html)
-  + [`HypreParMatrix`](http://mfem.github.io/doxygen/html/classmfem_1_1HypreParMatrix.html) and [`HypreParVector`](http://mfem.github.io/doxygen/html/classmfem_1_1HypreParVector.html)
-  + [`HypreSolver`](http://mfem.github.io/doxygen/html/classmfem_1_1HypreSolver.html) and other [hypre classes](http://mfem.github.io/doxygen/html/hypre_8hpp.html)
-
- The `general/` directory contains C++ classes that serve as utilities for
-  communication, error handling, arrays, (Boolean) tables, timing, etc.
-
- The `config/` directory contains build-related files, both for the plain
-  Makefile and the CMake build options.
-
- The `doc/` directory contains configuration for the Doxygen code documentation
-  that can either be build locally, or browsed online at
-  http://mfem.github.io/doxygen/html/index.html.
-
- The `data/` directory contains a collection of small mesh files, that are used
-  in the simple example codes and more fully-featured mini applications in the
-  `examples/` and `miniapps/` directories.
-
- See also the [code overview](http://mfem.org/code-overview/) section on the
-  MFEM website.
-
-## GitHub Workflow
-
-The GitHub organization, https://github.com/mfem, is the main developer hub for
-the MFEM project.
-
-If you plan to make contributions or will like to stay up-to-date with changes
-in the code, *we strongly encourage you to [join the MFEM organization](#mfem-organization)*.
-
-This will simplify the workflow (by providing you additional permissions), and
-will allow us to reach you directly with project announcements.
-
-

-  wrapper for MFEM.
-
- The [data](https://github.com/mfem/data) repository contains additional
-  (large) datafiles for MFEM.
-
-
-### New Feature Development
-
- A new feature should be important enough that at least one person, the
-  proposer, is willing to work on it and be its champion.
-
- The proposer creates a branch for the new feature (with suffix `-dev`), off
-  the `master` branch, or another existing feature branch, for example:
-
-  ```
-  # Clone assuming you have setup your ssh keys on GitHub:
-  git clone git@github.com:mfem/mfem.git
-
-  # Alternatively, clone using the "https" protocol:
-  git clone https://github.com/mfem/mfem.git
-
-  # Create a new feature branch starting from "master":
-  git checkout master
-  git pull
-  git checkout -b feature-dev
-
-  # Work on "feature-dev", add local commits
-  # ...
-
-  # (One time only) push the branch to github and setup your local
-  # branch to track the github branch (for "git pull"):
-  git push -u origin feature-dev
-
-  ```
-
- **We prefer that you create the new feature branch inside the MFEM organization
-  as opposed to in a fork.** This allows everyone in the community to collaborate
-  in one central place.
-
-  - If you prefer to work in your fork, please [enable upstream edits](https://help.github.com/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork/).
-
-  - Never use the `next` branch to start a new feature branch!
-
- The typical feature branch name is `new-feature-dev`, e.g. `pumi-dev`. While
-  not frequent in MFEM, other suffixes are possible, e.g. `-fix`, `-doc`, etc.
-
-
-### Developer Guidelines
-
- *Keep the code lean and as simple as possible*
-  - Well-designed simple code is frequently more general and powerful.
-  - Lean code base is easier to understand by new collaborators.
-  - New features should be added only if they are necessary or generally useful.
-  - Introduction of language constructions not currently used in MFEM should be
-    justified and generally avoided (so we can build on cutting-edge systems).
-  - We prefer basic C++ and the C++03 standard, to keep the code readable by
-    a large audience and to make sure it compiles anywhere.
-
- *Keep the code general and reasonably efficient*
-  - Main goal is fast prototyping for research.
-  - When in doubt, generality wins over efficiency.
-  - Respect the needs of different users (current and/or future).
-
- *Keep things separate and logically organized*
-  - General usage features go in MFEM (implemented in as much generality as
-    possible), non-general features go into external apps.
-  - Inside MFEM, compartmentalize between linalg, fem, mesh, GLVis, etc.
-  - Contributions that are project-specific or have external dependencies are
-    allowed (if they are of broader interest), but should be `#ifdef`-ed and not
-    change the code by default.
-
- Code specifics
-  - All significant new classes, methods and functions have Doxygen-style
-    documentation in source comments.
-  - Consistent code styling is enforced with `make style` in the top-level
-    directory. This requires [Artistic Style](http://astyle.sourceforge.net) (we
-    specifically use version 2.05.1). See also the file `config/mfem.astylerc`.
-  - Use `mfem::out` and `mfem::err` instead of `std::cout` and `std::cerr` in
-    internal library code. (You can use `std` in examples and miniapps.)
-  - When manually resolving conflicts during a merge, make sure to mention the
-    conflicted files in the commit message.
-
-### Pull Requests
-
- When your branch is ready for other developers to review / comment on
-  the code, create a pull request towards `mfem:master`.
-
- Pull request typically have titles like:
-
-     `Description [new-feature-dev]`
-
-  for example:
-
-     `Parallel Unstructured Mesh Infrastructure (PUMI) integration [pumi-dev]`
-
-  Note the branch name suffix (in square brackets).
-
- Titles may contain a prefix in square brackets to emphasize the type of PR.
-  Common choices are: `[DON'T MERGE]`, `[WIP]` and `[DISCUSS]`, for example:
-
-     `[DISCUSS] Hybridized DG [hdg-dev]`
-
- Add a description, appropriate labels and assign yourself to the PR. The MFEM
-  team will add reviewers as appropriate.
-
- List outstanding TODO items in the description, see PR #222 for an example.
-
- Track the Travis CI and Appveyor [continuous integration](#automated-testing)
-  builds at the end of the PR. These should run clean, so address any errors as
-  soon as possible.
-
-

-
-### Master/Next Workflow
-
-MFEM uses a `master`/`next`-branch workflow as described below:
-
- The `master` branch should always be of release quality and changes should not
-  be merged until they have been fully tested. This branch is protected, and
-  changes can only be made through pull requests.
-
- After approval, a pull request is merged manually (by MFEM developers) in the
-  `next` branch for testing and the `in-next` label is added to the PR.
-  This can be done as follows:
-
-  ```
-  # Pull the latest version of the "feature-dev" branch
-  git checkout feature-dev
-  git pull
-
-  # Pull the latest version of the "next" branch
-  git checkout next
-  git pull
-
-  # Merge "feature-dev" into "next", resolving conflicts, if necessary.
-  # Use the "--no-ff" flag to create a new commit with merge message.
-  git merge --no-ff feature-dev
-
-  # Push the "next" branch to the server
-  git push
-  ```
-
- After a week of testing in `next` (excluding bugfixes), both on GitHub, as
-  well as [internally](#tests-at-llnl) at LLNL, the original PR is merged into
-  `master` (provided there are no issues).
-
- After the merge, the feature branch is deleted (unless it is a long-term
-  project with periodic PRs).
-
- The `next` branch is used just for integrated testing of all PRs approved for
-  merging into `master` to verify that each works individually and that all of
-  them work as a group. This branch can be discarded at any time, though we
-  typically do that only at the end of a [release cycle](#releases).
-
-
-### Releases
-
- Releases are just tags in the `master` branch, e.g. https://github.com/mfem/mfem/releases/tag/v3.3.2,
-  and have a version that ends in an even "patch" number, e.g. `v3.2.2` or
-  `v3.4` (by convention `v3.4` is the same as `v3.4.0`.)  Between releases, the
-  version ends in an odd "patch" number, e.g. `v3.3.3`.
-
- We use [milestones](https://github.com/mfem/mfem/milestones) to coordinate the
-  work on different PRs toward a release, see for example the
-  [v3.3.2 release](https://github.com/mfem/mfem/milestone/1?closed=1).
-
- After a release is complete, the `next` branch is recreated, e.g. as follows
-  (replace `3.3.2` with current release):
-  - Rename the current `next` branch to `next-pre-v3.3.2`.
-  - Create a new `next` branch starting from the `v3.3.2` release.
-  - Local copies of `next` can then be updated with `git checkout -B next origin/next`.
-
-### Release Checklist
-
- [ ] Update the MFEM version in the following files:
-    - [ ] `CHANGELOG`
-    - [ ] `makefile`
-    - [ ] `CMakeLists.txt`
-    - [ ] `doc/CodeDocumentation.conf.in`
- [ ] (LLNL only) Make sure all `README.html` files in the source repo are up to date.
- [ ] Tag the repository:
-
-  ```
-  git tag -a v3.1 -m "Official release v3.1"
-  git push origin v3.1
-  ```
- [ ] Create the release tarball and push to `mfem/releases`.
- [ ] Recreate the `next` branch as described in previous section.
- [ ] Update and push documentation  to `mfem/doxygen`.
- [ ] Update URL shorlinks:
-    - [ ] Create a shortlink at [https://goo.gl/](https://goo.gl/) for the release tarball, e.g. http://mfem.github.io/releases/mfem-3.1.tgz.
-    - [ ] (LLNL only) Add and commit the new shorlink in the `links` and `links-mfem` files of the internal `mfem/downloads` repo.
-    - [ ] Add the new shortlinks to the MFEM packages in `spack`, `homebrew/science`, `VisIt`, etc.
- [ ] Update website in `mfem/web` repo:
-    - Update version and shortlinks in `src/index.md` and `src/download.md`.
-    -  Use [cloc-1.62.pl](http://cloc.sourceforge.net/) and `ls -lh` to estimate the SLOC and the tarball size in `src/download.md`.
-
-
-## LLNL Workflow
-
- The GitHub `master` and `next` branches are mirrored to the LLNL institutional
-  Bitbucket repository as `gh-master` and `gh-next`.
-
- `gh-master` is merged into LLNL's internal `master` through pull requests; write
-  permissions to `master` are restricted to ensure this is the only way in which it
-  gets updated.
-
- We never push directly from LLNL to GitHub.
-
- Versions of the code on LLNL's internal server, from most to least stable:
-  - MFEM official release on mfem.org -- Most stable, tested in many apps.
-  - `mfem:master` -- Recent development version, guaranteed to work.
-  - `mfem:gh-master` -- Stable development version, passed testing, you can use
-     it to build your code between releases.
-  - `mfem:gh-next` -- Bleeding-edge development version, may be broken, use at
-     your own risk.
-
-
-## Automated Testing
-
-MFEM has several levels of automated testing running on GitHub, as well as on
-local Mac and Linux workstations, and Livermore Computing clusters at LLNL.
-
-### Linux and Mac smoke tests
-We use Travis CI to drive the default tests on the `master` and `next`
-branches. See the `.travis` file and the logs at
-[https://travis-ci.org/mfem/mfem](https://travis-ci.org/mfem/mfem).
-
-Testing using Travis CI should be kept lightweight, as there is a 50 minute time
-constraint on jobs. Two virtual machines are configured - Mac (OS X) and Linux.
-
- Tests on the `master` branch are triggered whenever a PR is issued on this branch.
- Tests on the `next` branch are currently scheduled to run each night.
-
-### Windows smoke test
-We use Appveyor to test building with the MS Visual C++ compiler in a Windows
-environment, as well as to test the CMake build. See the `.appveyor` file and the
-build logs at
-[https://ci.appveyor.com/project/mfem/mfem](https://ci.appveyor.com/project/mfem/mfem).
-
-CMake is used to generate the MSVC Project files and drive the build.  A release
-and debug build is performed with a simple run of `ex1` to verify the executable.
-
-### Tests at LLNL

-##################################################################################

-#
-# This module implements standard behavior for XSDK CMake projects.  The main
-# thing it does in XSDK mode (i.e. USE_XSDK_DEFAULTS=TRUE) is to print out
-# when the env vars CC, CXX, FC and compiler flags CFLAGS, CXXFLAGS, and
-# FFLAGS/FCFLAGS are used to select the compilers and compiler flags (raw
-# CMake does this silently) and to set BUILD_SHARED_LIBS=TRUE and
-# CMAKE_BUILD_TYPE=DEBUG by default.  It does not implement *all* of the
-# standard XSDK configuration parameters.  The parent CMake project must do
-# that.
-#
-# Note that when USE_XSDK_DEFAULTS=TRUE, then the Fortran flags will be read
-# from either of the env vars FFLAGS or FCFLAGS.  If both are set, but are the
-# same, then FFLAGS it used (which is the same as FCFLAGS).  However, if both
-# are set but are not equal, then a FATAL_ERROR is raised and CMake configure
-# processing is stopped.
-#
-# To be used in a parent project, this module must be included after
-#
-#   PROJECT(${PROJECT_NAME}  NONE)
-#
-# is called but before the compilers are defined and processed using:
-#
-#   ENABLE_LANGUAGE(<LANG>)
-#
-# For example, one would do:
-#
-#   PROJECT(${PROJECT_NAME}  NONE)
-#   ...
-#   SET(USE_XSDK_DEFAULTS_DEFAULT TRUE) # Set to false if desired
-#   INCLUDE("${CMAKE_CURRENT_SOURCE_DIR}/stdk/XSDKDefaults.cmake")
-#   ...
-#   ENABLE_LANGUAGE(C)
-#   ENABLE_LANGUAGE(C++)
-#   ENABLE_LANGUAGE(Fortran)
-#
-# The variable `USE_XSDK_DEFAULTS_DEFAULT` is used as the default for the
-# cache var `USE_XSDK_DEFAULTS`.  That way, a project can decide if it wants
-# XSDK defaults turned on or off by default and users can independently decide
-# if they want the CMake project to use standard XSDK behavior or raw CMake
-# behavior.
-#
-# By default, the XSDKDefaults.cmake module assumes that the project will need
-# C, C++, and Fortran.  If any language is not needed then, set
-# XSDK_ENABLE_C=OFF, XSDK_ENABLE_CXX=OFF, or XSDK_ENABLE_Fortran=OFF *before*
-# including this module.  Note, these variables are *not* cache vars because a
-# project either does or does not have C, C++ or Fortran source files, the
-# user has nothing to do with this so there is no need for cache vars.  The
-# parent CMake project just needs to tell XSDKDefault.cmake what languages is
-# needs or does not need.
-#
-# For example, if the parent CMake project only needs C, then it would do:
-#
-#   PROJECT(${PROJECT_NAME}  NONE)'
-#   ...
-#   SET(USE_XSDK_DEFAULTS_DEFAULT TRUE)

-   Options:
-      -h|-help    Print this usage information and exit
-      -p|-par     Build the parallel MFEM library + examples + miniapps.
-                  The default is to build the serial MFEM library + examples +
-                  miniapps. The build can be customized by setting the variable
-                  'mfem_config' or by building separately and using '-b'
-      -g <dir> <pattern>
-                  Specify explicitly a group (dir + file pattern) to run; This
-                  option can be used multiple times to define multiple groups
-      -v          Enable valgrind
-      -o <dir>    [${output_dir:-"<empty>: output goes to stdout"}]
-                  If not empty, save output to files inside <dir>
-      -j <np>     [${make_j}] Specify the number of jobs to use for building
-      -c|-color   Always use colors for the status messages: OK, FAILED, etc
-      -b|-built   Do NOT rebuild the library and the executables
-      -t|-time    Measure and print execution time for each sample run
-      -s|-show    Show all configured sample runs and exit
-      -n          Dry run: replace "\$sample_run" with "echo \$sample_run"
-      <var>=<value>
-                  Set a shell script varible; see below for valid variables
-       *          Any other parameter is treated as <mfem_dir>
-      <mfem_dir>  [${mfem_dir}] is the MFEM source directory
-
-   This script tests all the sample runs listed in the begining comments of
-   MFEM's serial or parallel example and miniapp codes. The list of sample runs
-   is auto-generated and can be viewed with the -s|-show option.
-
-   The following shell script variables can be set with <var>=<value>:
-      output_dir [${output_dir}]
-         Same as '-o': if not empty, save output to files in that directory
-      output_sfx [${output_sfx}]
-         Suffix to append to the output files
-      mfem_config [${mfem_config}]
-         Set MFEM configuration options
-      make [${make}], mpiexec [${mpiexec}], mpiexec_np [${mpiexec_np}]
-         Their values can also set using the respective uppercase environment
-         variable
-      mfem_build_dir [${mfem_build_dir}]
-         Set this variable to something different from <mfem_dir> to use an
-         out-of-source build
-
-   For other valid variables, see the script source.
-
-   The following environment variables, if non-empty, are used:
-      MAKE, MPIEXEC, MPIEXEC_NP
-
-   Example usage:
-       $0 -s                [ Show all configured sample runs ]
-       $0 -o baseline       [ Serial build; run and save all built sample runs ]
-       $0 -p -o baseline    [ Parallel build; run and save all sample runs ]
-       $0 -b -g examples ex8.cpp [ Use the existing build; run ex8 sample runs ]

-// Description:  This example code solves the compressible Euler system of
-//               equations, a model nonlinear hyperbolic PDE, with a
-//               discontinuous Galerkin (DG) formulation.
-//
-//               Specifically, it solves for an exact solution of the equations
-//               whereby a vortex is transported by a uniform flow. Since all
-//               boundaries are periodic here, the method's accuracy can be
-//               assessed by measuring the difference between the solution and
-//               the initial condition at a later time when the vortex returns
-//               to its initial location.
-//
-//               Note that as the order of the spatial discretization increases,
-//               the timestep must become smaller. This example currently uses a
-//               simple estimate derived by Cockburn and Shu for the 1D RKDG
-//               method. An additional factor can be tuned by passing the --cfl
-//               (or -c shorter) flag.
-//
-//               The example demonstrates user-defined bilinear and nonlinear
-//               form integrators for systems of equations that are defined with
-//               block vectors, and how these are used with an operator for
-//               explicit time integrators. In this case the system also
-//               involves an external approximate Riemann solver for the DG
-//               interface flux. It also demonstrates how to use GLVis for
-//               in-situ visualization of vector grid functions.

-// Description:  This example code solves the compressible Euler system of
-//               equations, a model nonlinear hyperbolic PDE, with a
-//               discontinuous Galerkin (DG) formulation.
-//
-//               Specifically, it solves for an exact solution of the equations
-//               whereby a vortex is transported by a uniform flow. Since all
-//               boundaries are periodic here, the method's accuracy can be
-//               assessed by measuring the difference between the solution and
-//               the initial condition at a later time when the vortex returns
-//               to its initial location.
-//
-//               Note that as the order of the spatial discretization increases,
-//               the timestep must become smaller. This example currently uses a
-//               simple estimate derived by Cockburn and Shu for the 1D RKDG
-//               method. An additional factor can be tuned by passing the --cfl
-//               (or -c shorter) flag.
-//
-//               The example demonstrates user-defined bilinear and nonlinear
-//               form integrators for systems of equations that are defined with
-//               block vectors, and how these are used with an operator for
-//               explicit time integrators. In this case the system also
-//               involves an external approximate Riemann solver for the DG
-//               interface flux. It also demonstrates how to use GLVis for
-//               in-situ visualization of vector grid functions.
-//

-// Description:  This examples solves a quasi-static incompressible nonlinear
-//               elasticity problem of the form 0 = H(x), where H is an
-//               incompressible hyperelastic model and x is a block state vector
-//               containing displacement and pressure variables. The geometry of
-//               the domain is assumed to be as follows:
-//
-//                                 +---------------------+
-//                    boundary --->|                     |<--- boundary
-//                    attribute 1  |                     |     attribute 2
-//                    (fixed)      +---------------------+     (fixed, nonzero)
-//
-//               The example demonstrates the use of block nonlinear operators
-//               (the class RubberOperator defining H(x)) as well as a nonlinear
-//               Newton solver for the quasi-static problem. Each Newton step
-//               requires the inversion of a Jacobian matrix, which is done
-//               through a (preconditioned) inner solver. The specialized block
-//               preconditioner is implemented as a user-defined solver.
-//
-//               We recommend viewing examples 2, 5, and 10 before viewing this
-//               example.

-// Description:  This examples solves a quasi-static incompressible nonlinear
-//               elasticity problem of the form 0 = H(x), where H is an
-//               incompressible hyperelastic model and x is a block state vector
-//               containing displacement and pressure variables. The geometry of
-//               the domain is assumed to be as follows:
-//
-//                                 +---------------------+
-//                    boundary --->|                     |<--- boundary
-//                    attribute 1  |                     |     attribute 2
-//                    (fixed)      +---------------------+     (fixed, nonzero)
-//
-//               The example demonstrates the use of block nonlinear operators
-//               (the class RubberOperator defining H(x)) as well as a nonlinear
-//               Newton solver for the quasi-static problem. Each Newton step
-//               requires the inversion of a Jacobian matrix, which is done
-//               through a (preconditioned) inner solver. The specialized block
-//               preconditioner is implemented as a user-defined solver.
-//
-//               We recommend viewing examples 2, 5, and 10 before viewing this
-//               example.

-//               -Delta u = 1 with homogeneous Dirichlet boundary conditions.
-//               Specifically, we discretize using a FE space of the specified
-//               order, or if order < 1 using an isoparametric/isogeometric
-//               space (i.e. quadratic for quadratic curvilinear mesh, NURBS for
-//               NURBS mesh, etc.)
-//
-//               The example highlights the use of mesh refinement, finite
-//               element grid functions, as well as linear and bilinear forms
-//               corresponding to the left-hand side and right-hand side of the
-//               discrete linear system. We also cover the explicit elimination
-//               of essential boundary conditions, static condensation, and the
-//               optional connection to the GLVis tool for visualization.
-//
-//               This PUMI modification demonstrates how PUMI's API can be used
-//               to load a PUMI mesh classified on a geometric model and then

-//               model, "*.xmt_txt" and a SCOREC mesh "*.smb". The option "-o"
-//               is used for the Finite Element order and "-go" is used for the
-//               geometry order. Note that they can be used independently, i.e.

-// Description:  This example code solves a simple linear elasticity problem
-//               describing a multi-material cantilever beam.
-//
-//               Specifically, we approximate the weak form of -div(sigma(u))=0
-//               where sigma(u)=lambda*div(u)*I+mu*(grad*u+u*grad) is the stress
-//               tensor corresponding to displacement field u, and lambda and mu
-//               are the material Lame constants. The boundary conditions are
-//               u=0 on the fixed part of the boundary with attribute 1, and
-//               sigma(u).n=f on the remainder with f being a constant pull down
-//               vector on boundary elements with attribute 2, and zero
-//               otherwise. The geometry of the domain is assumed to be as
-//               follows:
-//                                        boundary
-//                                       attribute 2

-//
-//               The example demonstrates the use of high-order and NURBS vector
-//               finite element spaces with the linear elasticity bilinear form,
-//               meshes with curved elements, and the definition of piece-wise
-//               constant and vector coefficient objects. Static condensation is
-//               also illustrated.

-//               We recommend viewing Example 1 before viewing this example.

-//
-// Compile with: make ex1p

-// Sample runs:  mpirun -np 8 ex6p
-//
-// Description:  This is a version of Example 1 with a simple adaptive mesh
-//               refinement loop. The problem being solved is again the Laplace
-//               equation -Delta u = 1 with homogeneous Dirichlet boundary
-//               conditions. The problem is solved on a sequence of meshes which
-//               are adapted in a conforming (tetrahedrons) manner according
-//               to a simple SPR ZZ error estimator.
-//
-//               This PUMI variation also performs a "uniform" refinement,
-//               similar to MFEM examples, for coarse meshes. However, the
-//               refinement is performed using the PUMI API. A new option "-ar"
-//               is added to modify the "adapt_ratio" which is the fraction of
-//               allowable error that scales the output size field of the error
-//               estimator.
