+The newly released Version 3.1 of deal.II, an object-oriented finite
+element library, is available from the deal.II home-page at
+
+ http://gaia.iwr.uni-heidelberg.de/~deal
+
+It has significant improvements over the old version 3.0. See the news
+page at
+ http://gaia.iwr.uni-heidelberg.de/~deal/news/2000/3.0.0-vs-3.1.0.html
+
+deal.II is a C++ class library targeted at adaptive finite elements.
+It uses state-of-the-art programming techniques of the C++ programming
+language to offer you a modern interface to the complex data
+structures and algorithms required for locally refined meshes and
+enables you to use a variety of finite elements in one, two, and three
+space dimensions, as well as support for time-dependent problems.
+
+The library is written for research purposes and offers many features:
+- Support for one, two, and three space dimensions, using a unified
+ interface that enables writing programs almost dimension independent.
+
+- Handling of locally refined grids, including different adaptive
+ refinement strategies based on local error indicators and error
+ estimators.
+
+- Support for a variety of finite elements, including Lagrange
+ elements of order one through four, and discontinuous elements.
+
+- Extensive documentation: all documentation is available online in a
+ logical tree structure to allow fast access to the information you
+ need. If printed it comprises about 250 pages of tutorials, several
+ reports, and far more than 1,000 pages of programming interface
+ documentation with explanations of all classes, functions, and
+ variables.
+
+- Modern software techniques that make access to the complex data
+ structures and algorithms as transparent as possible. The use of
+ object oriented programming allows for program structures similar to
+ the structures in mathematical analysis.
+
+- Fast algorithms that enable you to solve problems with up to several
+ millions of degrees of freedom quickly. As opposed to programming
+ symbolic algebra packages the penalty for readability is low.
+
+- Support for several output formats, including some common formats
+ for visualization of scientific data.
+
+- Support for a variety of computer platforms, including multi-
+ processor machines.
+
+- Free source code under an Open Source license for noncommercial
+ purposes, and the invitation to contribute to further development of
+ the library.

+After almost one year of development, version 5.0 of the deal.II
+object-oriented finite element library has been released. It is
+available from the deal.II home-page at
+
+ http://www.dealii.org
+
+Version 5.0 is another major step for this library. The most important
+change is the addition of interfaces to the PETSc library to provide a
+second set of linear system support classes besides the original
+deal.II ones. Via PETSc and an interface to METIS, parallel finite
+element computations on clusters of computers have become as simple as
+sequential ones. Through this, the library has proven to support
+computations with more than 10 million unknowns.
+
+In addition to this, the most noteworthy changes are:
+- Two new example programs, demonstrating one-dimensional nonlinear
+ problems and parallel computations with PETSc
+- The use of doxygen for the generation of our several-thousand pages
+ strong documentation, with significantly better cross-linking between
+ pages
+- Much better support for three-dimensional computations. Several
+ topological restrictions on unstructured 3d meshes have been lifted,
+ and a number of long-standing bugs have been fixed. We can now also
+ read in 3d meshes with several 100,000 cells in a few seconds
+- Support for Raviart-Thomas elements in 2d and 3d.

+Version 8.4 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:
+- Parallel triangulations can now be partitioned in ways that allow weighting
+ cells differently.
+- Improved support for complex numbers throughout the library.
+- A new triangulation type that supports parallel computations but ensures
+ that the entire mesh is available on every processor.
+- An implementation of the Rannacher-Turek element, as well as an element that
+ extends the usual Q(p) elements by bubble functions.
+- Second and third derivatives of finite element fields are now computed
+ exactly.
+- The interface between finite elements, quadrature, mapping, and the FEValues
+ class has been rewritten. It is now much better documented.
+- Initial support for compiling with Visual C++ 2013 and 2015 under Windows
+ has been added.
+- Where possible, the 'gold' linker is used, dramatically speeding up linking
+- More than 140 other features and bugfixes.
