--- Comment #27 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Nothing changed in what options imply -Wunused-but-set-variable or -Wunused-but-set-parameter, just that those 2 options now mean the =3 level and users can explicitly use say -Wunused-but-set-variable=1 etc. to restore previous behavior.
