| A new cleanup and quick-assist has been added to remove unused parameters of private methods. If removing parameters might |
| lead to a conflict with an another method, the private method is renamed to be unique. The cleanup is not available if there |
| is a method reference to the method, as in <code>stream.filter(MyClass::foo)</code> |
| <p> |
| To apply the cleanup, select the <b>Remove unused private method parameters</b> checkbox on the <b>Unnecessary Code</b> tab in your cleanup profile:</p> |
