+## Version 5.0.1 (05-05-2023)
+
+### Changed
+
+- Bug fixes:
+  - bad constcorectness in arrays
+  - applyBC broken
+
+- Extending python API
+
 ## Version 5.0 (03-28-2023)
 
 ### Changed 
 
 - C++ standard 17 is now accepted
 - `Vector<T>` and `Matrix<T>` changed from internal types to Eigen::Matrix<T>
 - `VectorProxy<T>` and `MatrixProxy<T>` are now `Eigen::Map<Eigen::Matrix<T>>`
   This introduces a potential bug if codes like the following example where used:
   ```
   for(auto && v_ : make_view(vectors, dim)) {
     Vector<Real> v(v_);
     ...
   }
   ```
   With the new version the temporary vector `v` will be a deep copy of `v_`
   instead of a shallow copy as in the previous version
   
 ### Added
 
 - `make_view` as a static dimension version for vectors and matrices
   `make_view<size>(vectors)` and `make_view<rows, cols>(matrices)`
 - `zip` iterators can be named, in which case the
   return tuple is a `named_tuple`.
   ```
   for(auto && t : zip("a"_n = as, "b"_n = bs)) {
     auto && a = t["a"_n];
     auto && b = t["b"_n];
     ...
   }
   ```
   
 ### Deprecated
 
 - `begin_reinterpret` and `end_reinterpret` are error prone and deprecated in favor of `make_view`
 - `storage()` members are deprecated in favor of `data()` in order to be compatible with the STL
 - `get(.*)Energy(ElementType type, Idx index)` are deprecated in favor of `get(.*)Energy(const Element & element)`
   elements can be implicitly created, `getEnergy({type, index, _not_ghost})`
 - `begin_(node|element)_group` and `end_(node|element)_group` are replaced by `iterate(Node|Element)Groups` 
 - In the python interface:
   - the global `setDebugLevel`, `getDebugLevel` and `printBacktrace` were moved in the sub-module `debug`
   - the call to `finalize` is not needed
   - `applyDirichketBC` was replaced by `applyBC`
 
 ### Deleted
 
 - `getForce`, `firstType()`, `lastType()` that where deprecated in version 4.0
 
 
 ## Version 4.0 (09-21-2021)
 
 ### Added
   
 - pybind11 binding
 - contact mechanics model
 - phase field model
 - Added a Changelog
 
 ### Changed
 
 - transferred CI from jenkinsfile to gitlab CI/CD
 - API changes to make container more STL compatible
   - clear does not set to 0 anymore but empties containers
   - empty does not empty containers but tells if the container is empty
   - zero replace the old empty and set containers to 0
   
 ### Deprecated
 
 - `getForce` in the `SolidMechanicsModel` becomes `getExternalForce`
 - `firstType()`, `lastType()` replaced by `elementTypes()`
 
 ## Version 3.2 (not released)
 
 ### Added
 
 - Activating PETSc solver back with the new solver interface
 
 ### Deprecated 
 
 - deprecating old C++ 03 code
 
 
 ## 3.0 (2018-03)
 
 ### Added
 
 - Parallel cohesive elements
 - Element groups created by default for “physical_names”
 - Named arguments for functions (e.g. model.initFull(_analysis_method = _static))
 
 ### Changed
 
 - Models using new interface for solvers
   - Same configuration for all models
   - Solver can be configured in input file
 - Only one function to solve a step model.solveStep()
 - Simplification of the parallel simulation with the mesh.distribute() function
 - Switch from C++ standard 2003 to 2014 Example of changes implied by this:
 
    for (Int g = _not_ghost; g <= _ghost; ++g) {
       GhostType gt = (GhostType)g;
       Mesh::type_iterator it = this->mesh.firstType(spatial_dimension, gt);
       Mesh::type_iterator end = this->mesh.lastType(spatial_dimension, gt);
       for (; it != end; ++it) {
         ElementType & type = *it;
         ...
       }
     }
 
   becomes:
 
     for (auto ghost_type : ghost_types) {
       for (auto type : mesh.elementTypes(spatial_dimension,
                                          ghost_type)) {
         ...
       }
     }
 
 ### Deleted
 
 - PETSc interface temporary inactive
 - Periodic boundary condition temporary inactive
