-
- Added average fluxes to `NumericalFlux` (formerly `RiemannSolver`)
-  and `FluxFunction`.
-
- Added component-wise upwinded flux (`ComponentwiseUpwindFlux`).
-
- Added support for H(div) spaces in class QuadratureInterpolator. For now, only
-  (vector) VALUES, (vector) PHYSICAL_VALUES, and PHYSICAL_MAGNITUDES evaluations
-  are implemented. [PR #4669]
-
 Meshing improvements
 --------------------
- Added native AD support for numerous TMOP metrics that didn't have first or
-  second derivative implementations.
-
 - The ExodusII reader now handles pyramid and wedge element types. Mixed meshes
  are also supported.

- Added support for nonuniform anisotropic (nonconforming) mesh refinement with
-  arbitrary spacing in each direction, for quadrilateral (2D) and hexahedral
-  (3D) meshes. This enables in particular 3:1 refinement, as demonstrated in the
-  new meshing miniapp ref321.

 - Added support for custom interpolation procedure in FindPointsGSLIB.

- `FiniteElementSpace` has new methods to directly set prolongation and
-  restriction operators to arbitrary sparse matrices.
-
- There are new convenience constructors for NURBS patches and knot vectors.
-
- Added convenience methods for manipulating boundary attribute marker arrays;
-  `(Par)Mesh::MarkExternalBoundaries`, `(Par)Mesh::UnmarkInternalBoundaries`,
-  `(Par)Mesh::MarkNamedBoundaries`, and `(Par)Mesh::UnmarkNamedBoundaries`.
-  See examples `ex1.cpp`, `ex1p.cpp`, and `ex11p.cpp` for basic usage.
-
- Added `(Par)Mesh::GetExteriorFaceMarker` for identifying faces on the
-  exterior of the mesh irrespective of their presence in the list of "boundary
-  elements".
-
- Added methods to `(Par)FiniteElementSpace` to identify all degrees of freedom
-  located on the exterior of the domain without reference to the list of
-  "boundary elements"; `GetExteriorVDofs` and `GetExteriorTrueDofs`.
-
- `LinearFormIntegrator` and `NonlinearFormIntegrator` (including
-  `BilinearFormIntegrator`) now all inherit from a base class `Integrator`
-  that combines some logic related to selecting quadrature rules. This includes
-  a virtual method `Integrator::GetDefaultIntegrationRule`, which should be
-  favored over directly defining a default integration rule in the element-level
-  assembly routines (although the latter is still possible, by leaving the new
-  virtual method as its default base implementation of returning `NULL`).
-
- Updated the benchmarks (in tests/benchmarks) to work with the latest Google
-  Benchmarks classes (version 1.9.1). Renamed the MFEM_ENABLE_GOOGLE_BENCHMARKS
-  CMake option to just MFEM_ENABLE_BENCHMARKS.
-
- Changed the name of `IterativeSolverMonitor` to `IterativeSolverController`
-  which now allows for declaring convergence by a user defined criterion. For
-  backward compatibility, the old name is still available.

- API change: 'TMOP_Metric_skew2D' has been marked as deprecated.
-
 - API change: in class GridFunction, 'fec' was renamed to 'fec_owned'.

-CMAKE_INSTALL_LIBDIR is lib. This is in contrast to the default behavior for
