Breaking changes ⚠️

Function	Change	Use instead
Model.to_file(file_path, use_var_names)	Renamed with changes	Model.write(file_path). Note: use_var_names should now be set when initializing the model.
Model.solve(solver, directory, use_var_names, log_fn, warmstart_fn, basis_fn, solution_file, log_to_console)	Renamed with changes	Model.optimize(). Note: parameters should be set through other means (e.g. model.attr.Silent = True instead of log_to_console=False)
Expression.value	Renamed	Expression.evaluate()
Config.print_float_precision	Renamed	Config.float_to_str_precision
Constraint.slack	Renamed	Constraint.attr.slack (Gurobi only)
Variable.RC	Renamed	Variable.attr.RC (Gurobi only)
Constraint.relax(...)	Changed behavior	Same as before except that it must be called before adding a constraint to the model.
Model.params (Gurobi only)	Changed behavior	Same as before except that if the parameter needs to be set during environment creation, instead use: Model(solver_env={"server_name":"bla"})
.to_str(...) and .to_str_table(...)	Changed signature	Parameters moved to pf.Config

Also:

• ⚠️ Gurobi must be installed through their website (not via pip) as we now use the Gurobi C API (not the Python API). Here is a way to automate this in a build environment. ⚠️
• Support for Python 3.8 is dropped.
