Reset random seed value for cplex 12.10, was different from COS release value.

Add fast methods for changing batches of variable bounds: Model.change_var_lower_bounds, Model.change_var_upper_bounds.

Add support for exporting solutions and solution pools to SOL format.

Method CpoModel.add() now accepts multiple expressions (or lists of expressions) to add to the model.

Interval variable solutions tuples are now named tuples.

Optimize generation of CPO expressions from Python expressions.

Support solver parameter ModelAnonymizer to generate random names for all model elements (except KPIs) in the CPO file format.

Replace context attribute solve_with_start_next by solve_with_search_next, keeping ascending compatibility.

Fixed a bug in LP export for multi-objective models with no priorities passed.

Fixed documentation references to class Var, moved from linear to dvar.

Display of expressions in constraints is customizable: use a space separator (or not), set a maximum length for very long expression.

Naming expressions is now deprecated, use a temporary variable if needed.

Added contextual function to temporarily modify aspects of the model: model_parameters to change parameters in a block, model_objective to set a temporary objective in a block.

Add support for importing solution from a different model, provided variables can be matched between both models (Model.import_solution).
