DNSName can now take care of case conversion when comparing using traits. It still intentionally doesn't implement operator ==; you have to explicitly decide whether you want case-sensitive or case-insensitive comparison. This change makes caches (and /etc/hosts) case-transparent: we will now match domains if they're the same except for the case.
