    Release Notes: This version marks a major milestone. Important new features include improved support for functions, automatic solution of linear and nonlinear partial differential equations, and a conversion script for importing meshes from Gmsh and TetGen. Several new and instructional demo programs have been added, libtool is now used to build shared libraries, the manual has been improved, and updates have been made for the latest versions of PETSc (2.3.1) and FFC (0.3.0).

      Release Notes: The solver for Navier-Stokes equations solver is back online; demo problems are avaliable in 2D and 3D. Support for 2D/3D demo problems has also been added for Stokes equations and the Poisson equation. There are some changes to the parameter system, as well as minor changes to the class for boundary conditions.

        Release Notes: This release greatly improves the support for mixed and vector-valued discrete functions. A new nonlinear solver was added. Other changes include support for the matrix market format, improved export to VTK, a reorganized and improved build system, portability updates, and compatibility updates for the latest version of FFC.

          Release Notes: This version adds support for the new FFC BLAS mode that improves compile time and may improve run time for high-order forms. In addition, a number of minor bugs have been fixed and a new experimental SWIG-based Python interface (PyDOLFIN) has been added.

            Release Notes: This release adds support for general mixed elements and includes a new module for the solution of Stokes' equations with Taylor-Hood elements. An eigenvalue solver has been added, and the VTK output format now supports time-dependent solutions.

              Release Notes: This version adds full support for general order Lagrange finite elements on both triangles and tetrahedra. Other changes include updates for PETSc version 2.3.0, a new interface to Paraview/VTK, improved assembly, and a number of important bugfixes and cleanups. A simple demo program with a rudimentary manual has also been added.

                Release Notes: This release adds many small fixes and improvements. Most notably, the ODE solvers have been improved, and support has been added for assembly of non-square systems.

                  Release Notes: This version adds experimental support for general order Lagrange elements (through FIAT/FFC). Mesh entities including triangles and tetrahedrons are now locally sorted according to the convention used by FFC.

                    Release Notes: Two new modules have been moved to the new codebase; both the convection-diffusion solver and the linear elasticity solver are now based on FFC/PETSc. Furthermore, the multi-adaptive ODE-solver has been greatly improved. In addition, a lot of old code has been cleaned out, a number of important bugs have been fixed, and the previously broken curses interface is functioning again.

                      Release Notes: Support was added for mixing multiple finite elements in the same variational formulation (through FFC). This version depends on PETSc version 2.2.1 and FFC version 0.1.6. Support has been dropped for PETSc 2.2.0. Functionality was added for easy creation of simple meshes (unit square and unit cube). The homotopy solver was also improved.
