+    - when using clingo module, the models contains only the output atoms, not everything
     - access to the answer set number with `.with_answer_number`
     - parsing and string reproduction of nested atoms such as `a((a("g(2,3)",(2)),))` is now correctly handled and tested
     - fix the `models.command` output when clingo module is used
