+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: step-19 introduces particle methods,
+    and step-68 uses these for tracking locations in a flow
+    field. step-66 is a matrix-free geometric multigrid solver for a
+    nonlinear problem. step-71 and step-72 illustrate automatic and
+    symbolic differentiation. step-77 demonstrates deal.II's SUNDIALS
+    interfaces to solve a nonlinear problem. step-74 shows the SIPG
+    approach to discontinuous Galerkin methods. step-76 is an explicit
+    integrator for the Euler equations. step-78 solves the
+    Black-Scholes equations, and step-79 solves a topology
+    optimization problem.
+
+  - 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 list of changes at
+    https://www.dealii.org/developer/doxygen/deal.II/changes_between_9_2_0_and_9_3_0.html
+
+The main features of deal.II are:
+  - Extensive documentation and 76 fully-functional example programs
+  - Support for dimension-independent programming
+  - Locally refined adaptive meshes
+  - Multigrid support
+  - A zoo of different finite elements
+  - Fast linear algebra
+  - Built-in support for shared memory and distributed parallel computing,
+    scaling from laptops to clusters with 100,000+ processor cores
+  - Interfaces to Trilinos, PETSc, METIS, UMFPACK and other external software
+  - Output for a wide variety of visualization platforms.
