+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 a 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.
+- Support for more compilers and operating systems
+
+A comprehensive list of new features and fixed bugs can be found at
+     http://www.dealii.org/news/4.0.0-vs-5.0.0.html
+
+All main features of the previous versions have been continued and
+improved:
+- Support for dimension-independent programming
+- Extensive documentation and working example programs
+- Locally refined grids
+- A zoo of different finite elements
+- Fast linear algebra
+- Built-in support for symmetric multi-processing (SMP)
+- Output for a variety of visualization platforms.
+
+deal.II can be downloaded for free and is distributed under an Open
+Source license.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
