There should be a release note :)

I think I agree with @mizvekov's idea of merging the parameter checks into SemaType; we can probably in part reuse GetTypeForDeclarator. I would appreciate it if we can see some exploration here.

Another thing is that we need to make sure the values of such require expressions are false, aligning with other compilers.
