+Version 9.3.0 of deal.II, the object-oriented finite element library
+awarded the J. H. Wilkinson Prize for Numerical Software, has been
+released. It is available for free under an Open Source license from
+the deal.II homepage at https://www.dealii.org/
+
+The major changes of this release are:
+- Ten new tutorial programs covering: particle methods, tracking
+  locations in a flow field, a matrix-free geometric multigrid solver
+  for a nonlinear problem, automatic and symbolic differentiation,
+  SUNDIALS interfaces for nonlinear problems, SIPG approach to
+  discontinuous Galerkin methods, an explicit integrator for the
+  Euler equations, a solver for the Black-Scholes equations, and
+  topology optimization problems.
+- Experimental support for simplex and mixed meshes.
+- Improved flexibility of the particle infrastructure.
+- Support for global-coarsening multigrid algorithms.
+- Advances in the matrix-free infrastructure.
+- Usage of MPI-3.0 shared-memory features to reduce memory footprint
+- Improved support for evaluation and integration at arbitrary points
+- More than 210 other new features, improvements, and bugfixes.
+For more information see the preprint at https://www.dealii.org/deal93-preprint.pdf
+
+The main features of deal.II are:
+- Extensive documentation and 76 fully-functional example programs
+- Support for dimension-independent programming
+- Locally refined adaptive meshes with multigrid support
+- A zoo of different finite elements and fast linear algebra
+- Built-in support for shared memory and distributed parallel computing,
+- Interfaces to Trilinos, PETSc, METIS, UMFPACK and other external software
+- Output for a wide variety of visualization platforms.
