Dear GetFEM++ users,

GetFEM++ 5.0 is released. This is a major release of GetFEM++. The main 
evolution is the generalization of the use of the high-level generic assembly 
for a more easy writting of nonlinear coupled problems. The few 
incompatibilities come from the fact that a certain number of tools have been 
re-designed (mainly Nitsche’s bricks and time integration schemes) and the old 
brick system (from 1.7 release) have been definitevely unplugged.

The main changes are:

- Standard bricks (generic elliptic, elasticity ...) are now based on the 
high-level generic assembly.
- Nitsche’s bricks have been re-designed.
- The support for time integration schemes has been re-designed.
- The support for large sliding contact has been improved (still a work in 
- Import of GMSH meshes has been improved.
- New tutorial and new Python/Scilab/Matlab demos.
- Allowing tensor field for model data.
- Cleaning/deletion of some obsolete files, including the old brick system.
- MPI and OpenMP parallelization of the high-level generic assembly.
- The use of mu_parser have been replaced by the use of the high-level generic 
assembly language. mu_parser in no longer a dependence of GetFEM++.
- Add of “elementary transformations” in the high-level generic assembly to 
allow for instance a local projection of a finite element on a lower level 
element to perform a reduction such as the one used in MITC element.
- Macro definition in the high-level generic assembly language.
- Numerical continuation/bifurcation detection/branching improved.
- Matrix exponential and logarithm operators added to the high-level generic 
- Allowing the use of C++11 feature.
- New im_data object version to store and interpolate data on the gauss points 
of a boundary.
