Adding #relenng to reviewers as I have no idea about procedures for touching old release notes.

I'm not sure there is any established procedure for editing old release documents, but as far as I'm concerned: Go for it. I consider "we forgot to remove this from the release docs when the driver was removed" to be in the same category as "fixing typos" -- we're not trying to rewrite history, just correcting an accidental and harmless error.

That's what I was thinking of it as, thanks!
