Ok.  It needs an entry in changes.html.

Do you plan to backport this change?

Did you consider using an alternate option name instead of changing
it in an incompatible way?  I realize SUSE will need to backport this
thus any user will need to do functional testing to see whether his
compiler implements the new or old semantics?
