And there is usually distinction between "bug fixes" and "security patches." Everyone knows Apple posts the CVE disclosures some time after the updates (sometimes with more to follow days later), but these are never specified directly in the release notes. I don't recall Apple ever withholding non-security release notes, something that would at least be out of the ordinary. If non-security-related bugs were fixed, as would be implied by the MR quote, then they should be disclosed in the release notes as they normally are. That's what I was complaining about.
