### Changed
|
||||
|
||||
- Proxied DNS-over-HTTPS queries are now only accepted from proxy servers on the
|
||||
`trusted_proxies` list ([#2799]).
|
||||
- Clients who are blocked by access settings now receive a `REFUSED` response
|
||||
when a protocol other than DNS-over-UDP and DNSCrypt is used.
|
||||
- `querylog_interval` setting is now formatted in hours.

|
||||
|
||||
- Wrong IP address for proxied DNS-over-HTTPS queries ([#2799]).

- Conflicts between IPv4 and IPv6 DNS rewrites ([#3343]).
|
||||
- Letter case mismatches in `CNAME` filtering ([#3335]).
