# MIPLearn: Changelog

### Changed
- Variables are now referenced by their names, instead of tuples `(var_name, index)`. This change was required to improve the compatibility with modeling languages other than Pyomo, which do not follow this convention. The functions `get_variable_category` and `get_variable_features` now have the following signature:
````python
def get_variable_features(self, var_name: str) -> List[float]:
pass
def get_variable_category(self, var_name: str) -> Optional[Hashable]:
pass
````
- Variables are now referenced by their names, instead of tuples `(var_name, index)`. This change was required to improve the compatibility with modeling languages other than Pyomo, which do not follow this convention. For performance reasons, the functions `get_variable_features` and `get_variable_categories` should now return a dictionary containing categories and features for all relevant variables. Previously, MIPLearn had to perform two function calls per variable, which was too slow for very large models.
- Internal solvers must now be specified as objects, instead of strings. For example,
```python
solver = LearningSolver(
