+Version 8.5.0 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:
+
+- The CellDataStorage class provides a mechanism to store and communicate
+  user-defined data on each cell.
+- The MappingManifold class provides mappings between the reference cell and a
+  mesh cell that is exact, rather than the usual polynomial approximations of
+  a manifold.
+- Various improvements for high-order elements, including a switch of support
+  points in FE\_Q and FE\_DGQ to Gauss-Lobatto support points, stable
+  evaluation of high-order Legendre polynomials, and several bugfixes for
+  high-order polynomial mappings defined through the MappingQ class.
+- The LinearOperator class has been extended by a generic ``payload''
+  mechanism that allows the attachment of arbitrary additional information to
+  a LinearOperator.
+- A dedicated physics module has been created to provide some standard
+  definitions and operations used in continuum mechanics.
+- The FE_Enriched class implements the operation of enriching the finite
+  element space of an underlying element.
+- The FESeries namespace provides expansions of a finite element solution in
+  terms of different, hierarchical bases.
+- New tutorial programs step-55, step-56, and step-57; as well as updates to
+  step-27, step-37, and step-44. In addition, the separate code gallery of
+  deal.II has gained a number of new entries.
+- Static code analyzers are valuable tools to improve and maintain the quality
+  of the code in our library in addition to build and regression tests for a
+  variety of setups. This release was tested with Cppcheck, PVS-Studio, and
+  Coverity-Scan.
+- More than 240 other features and bugfixes.
+
+For more information see
+- the preprint at https://www.dealii.org/deal85-preprint.pdf
+- the list of changes at
+  https://www.dealii.org/developer/doxygen/deal.II/changes_between_8_4_2_and_8_5_0.html
+
+The main features of deal.II are:
+- Extensive documentation and 55 working 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 10,000s of processor cores
+- Interfaces to Trilinos, PETSc, METIS, UMFPACK and other external software
+- Output for a wide variety of visualization platforms.
