-Version 4.6.1 (development)
+Version 4.5.3 (development)
 ===========================
 
-Meshing improvements
---------------------
-- Introduced formulas for refinement of patches in NURBS meshes. Refinement by
-  arbitrary integer factors is also enabled, e.g. in the mesh-explorer miniapp.
-  NURBS coarsening and knot removal are also introduced.
-
-Discretization improvements
----------------------------
-- Introduced support for higher order non conformal Nedelec elements on
-  simplices in ParMesh.
-- Introduced support for internal boundary elements in nonconformal adapted
-  meshes.
-
-- Added functionality for construction of cut-surface and cut-volume
-  IntegrationRules through a moment-fitting approach. The cut is specified by
-  the zero level set of a Coefficient. See fem/intrules_cut.hpp and Example 38.
-
-- Added a new nonlinear integrator, `HyperbolicFormIntegrator`. This implements 
-  both element-wise weak divergence and face-wise numerical flux for a general
-  system of hyperbolic conservation laws. To use this integrator for a specific
-  flux function, users can define a derived class of `FluxFunction`. Currently,
-  advection, Burgers', shallow-water, Euler equations (see, Example 18) are
-  available.
-
-GPU support
-----------------------------
-- Added support for full assembly on simplices.
-- Added functionality for BilinearFormIntegrators to use kernels that work for both
-  tensor and unstructured elements.
-- Added partial assembly for linear elasticity. Does not use sum factorization for now.
-
 New and updated examples and miniapps
 -------------------------------------
-- Added a new block solver in miniapp/solvers for the Darcy problem.
-  The new solver is based on a Bramble-Pasciak preconditioning. User can
-  use and implement their own preconditioner for the mass matrix.
+- Added a new example code, Example 36/36p, to demonstrate the solution of
+  the obstacle problem with a new finite element method.
 
-- Added miniapp to demonstrate new elasticity integrator and unstructured element GPU support,
-  and a block diagonal preconditioner using low order refinement. Allows comparison with
-  currently existing legacy mode integrator. See miniapps/solvers/lor_elast.
+- Added a new miniapp, Mesh Quality, for evaluating mesh quality using size,
+  skewness, and aspect-ratio computed from the Jacobian of the transformation.
 
-Miscellaneous
--------------
-- Added support for single and double precision, with corresponding hypre build.
-  Generalized the floating point type from `double` to `real_t`. For more
-  details see https://github.com/orgs/mfem/discussions/4207.
-
-- The ReadCubit Genesis mesh importer has been rewritten to improve readability.
-
-- Updated the Doxygen documentation style, which now requires Doxygen version
-  1.9.8 or later. See the doc/ directory.
-
-- Improved thread safety for global variables in the library, for example
-  IntegrationRules IntRules, RefinedIntRules, GeometryRefiner
-  GlobGeometryRefiner, and FiniteElement::dof2quad_array.
-
-- PETSc integration now generally requires PETSc version 3.21 or later, though
-  depending on the functionality older versions may still work.
-
-- RAJA backend will use seq_exec for serial loop execution when RAJA
-  v2023.06.00 and beyond is detected as loop_exec is deprecated.
-
-- Adding named attribute sets and basic supporting methods to the Mesh class as
-  a convenient means of referring to sets of domain or boundary attribute
-  numbers. Also adding related serial and parallel examples which illustrate.
-
-Version 4.6, released on September 27, 2023
-===========================================
-
-- MFEM is now available in Homebrew and can be installed on a Mac with just
-  "brew install mfem". See https://formulae.brew.sh/formula/mfem.
-
-Meshing improvements
---------------------
-- Added asymptotically-balanced TMOP compound metrics 90, 94, 328, 338. A new
-  tool, tmop-metric-magnitude, can be used to track how metrics change under
-  geometric perturbations. See miniapps/tools.
-
-- Several NURBS meshing improvements:
-  * Support for free connectivity of NURBS patches allowing for more complex
-    patch configurations such as C-meshes.
-  * New methods to set and get attributes on NURBS patches and patch boundaries.
-  * The edge to knot map for NURBS meshes can be determined automatically. It is
-    no longer needed to specify this in the NURBS mesh.
-  * Added curve interpolation method for NURBS.
-  * Added new small miniapp for printing of shape functions of a KnotVector
-  * See miniapps/nurbs for example meshes and miniapps.
-
-Discretization improvements
----------------------------
-- SubMesh and ParSubMesh have been extended to support the transfer of
-  Nedelec and Raviart-Thomas finite element spaces.
-
-- Added support for partial assembly on NURBS patches, and NURBS-patch sparse
-  matrix assembly. Patch matrix assembly includes the option to use reduced
-  approximate integration rules, computed by the newly implemented non-negative
-  least-squares (NNLS) solver.
-
-- Support for parallel transfer of H1 fields using the low-order refined (LOR)
-  transfer operators in L2ProjectionGridTransfer
-
-- Added KDTree class for 2D/3D set of points, which is then utilized in the new
-  KDTreeNodalProjection class to project a function defined on an arbitrary set
-  of points onto an MFEM grid function. This functionality is demonstrated in
-  the nodal-transfer miniapp. The current implementation is serial only. Further
-  extensions can include search in arbitrary dimensional spaces.
-
-- Added support for p-refined meshes in GSLIB-FindPoints.
-
-- Device kernels can now access device-specific DOF and quadrature limits using
-  the DofQuadLimits structure, allowing increased limits when executing on CPU.
-  The limits for the runtime selected device can be accessed in host code using
-  DeviceDofQuadLimits::Get(). The global constants MAX_D1D and MAX_Q1D are no
-  longer available.
-
-- Face restriction operators for Nedelec and Raviart-Thomas finite element
-  spaces are now supported through the ConformingFaceRestriction class.
-
-- VectorFEBoundaryFluxLFIntegrator is now supported on device/GPU.
-
-Linear and nonlinear solvers
-----------------------------
-- Updated the MUMPS interface to support multiple right-hand sides, block
-  low-rank compression, builds using 64-bit integers, and other improvements.
-
-- Added an interface to the MKL Pardiso sparse direct solver developed by Intel.
-  The interface provides a serial (OpenMP shared memory) version of Pardiso for
-  use with SparseMatrix. This complements the existing parallel (MPI distributed
-  memory) version already available through the CPardiso MFEM integration.
-
-- Added HIP support to the PETSc and SUNDIALS interfaces.
-
-- Efficient GPU-accelerated LOR assembly now supports surface meshes.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new H(div) solver miniapp demonstrating the use of a matrix-free
-  saddle-point solver methodology, suitable for high-order discretizations and
-  for GPU acceleration. Examples illustrating the solution of Darcy and grad-div
-  problems are included. See miniapps/hdiv-linear-solver.
+- Added a new miniapp for interface and boundary fitting to implicit domains
+  defined using level-set functions. See miniapps/meshing/pmesh-fitting.cpp
 
 - Added new Discontinuous Petrov-Galerkin (DPG) miniapp which includes serial
   and parallel examples for diffusion, convection-diffusion, acoustics and
   Maxwell equations. The miniapp includes new classes such as (Par)DPGWeakForm,
   (Par)ComplexDPGWeakForm and (Complex)BlockStaticCondensation. Three new
   integrators are added in support of DPG systems: TraceIntegrator,
-  NormalTraceIntegrator and TangentTraceIntegrator. See miniapps/dpg.
+  NormalTraceIntegrator and TangentTraceIntegrator.
 
-- Added a new miniapp that implements the SPDE method for generating Gaussian
-  random fields of Matern covariance. The resulting random field can be used,
-  e.g., to model material uncertainties. See miniapps/spde.
+- Added new SubMesh examples demonstrating source terms and boundary conditions
+  transferred from SubMesh objects.
 
-- Added a new parallel LOR transfer miniapp, plor-transfer, which mirrors the
-  functionality of the serial LOR transfer miniapp. See miniapps/tools.
-
-- New serial miniapp, nodal-transfer, demonstrating the use of KDTree to map a
-  parallel grid function to a different parallel partitioning of the same mesh.
-
-- Added 3 additional TMOP miniapps in miniapps/meshing:
-  * Mesh-Quality evaluates quality using size, skewness, and aspect-ratio
-    computed from the Jacobian of the transformation.
-  * Mesh-Fitting can be used for interface and boundary fitting to implicit
-    domains defined using level-set functions.
-  * Fit-Node-Position fits selected mesh nodes to specified positions, while
-    maintaining overall mesh quality.
-
-- Added 4 new example codes:
-  * Example 34/34p solves a simple magnetostatic problem where source terms and
-    boundary conditions are transferred with SubMesh objects.
-  * Example 35p implements H1, H(curl) and H(div) variants of a damped harmonic
-    oscillator with field transfer using SubMesh objects.
-  * Example 36/36p demonstrates the solution of the obstacle problem with a new
-    finite element method (proximal Galerkin).
-  * Example 37/37p demonstrates topology optimization with MFEM.
+- Added a new H(div) solvers miniapp in miniapps/hdiv-linear-solver,
+  demonstrating the use of a matrix-free saddle-point solver methodology,
+  suitable for high-order discretizations and for GPU acceleration. Examples
+  illustrating the solution of Darcy and grad-div problems are included.
 
 - Added a random refinement option to the mesh-explorer miniapp to assist users
   in experimenting with nonconforming meshes.
 
 - Moved the distance solver methods from miniapps/shifted to miniapps/common.
 
+Meshing improvements

+
+Integrations, testing and documentation
+---------------------------------------
+- Added an address sanitizer GitHub action for a serial build/test on Ubuntu,
+  based on Clang/LLVM (https://clang.llvm.org/docs/AddressSanitizer.html).
+
 Miscellaneous
 -------------
 - Improved lambda body debugging with the addition of mfem::forall functions.

-however you can build it locally too:
+#### 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 build -f config/docker/Dockerfile.base -t ghcr.io/mfem/mfem-ubuntu-base .
-```
-
-To shell into the container:
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu-base bash
-```
-
-Change directory to the mfem environment, setup spack, and activate the environment:
-
-```bash
-source /opt/spack/share/spack/setup-env.sh
-cd /opt/mfem-env/
-spack env activate .
-```
-
-Note that this environment is installing to the view at `/opt/view`. Since the environment
-knows to install mfem from `/code` this means that you could make changes in the container (or bind
-`/code` to your container) and then update spack:
-
-```bash
-# Note that concretization takes a hot minute!
-$ spack install
-```
-
-And if you want to load mfem:
-
-```bash
-$ spack load mfem
-$ env | grep mfem
-```
-
-In this development container, you can find the examples and miniapps alongside
-mfem under `/code`:
-
-```bash
-cd /code/examples
-```
-```bash
-$ ./ex0
-```
-```console
-Options used:
-   --mesh ../data/star.mesh
-   --order 1

-   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
-```
-
-This container is likely ideal for someone that wants to develop mfem itself.
-For other use cases, we recommend using the slimmer image. As an example,
-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 $PWD:/code bash
+$ 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.
