## [v0.107.0] - 2021-12-21

### Added

  log entries concerning cached responses won't include that information.

- Setting the timeout for IP address pinging in the "Fastest IP address" mode
  through the new `fastest_timeout` field in the configuration file ([#1992]).

- Optimistic cache ([#2145]).
- New possible value of `6h` for `querylog_interval` setting ([#2504]).
- Blocking access using client IDs ([#2624], [#3162]).
- `source` directives support in `/etc/network/interfaces` on Linux ([#3257]).
- RFC 9000 support in DNS-over-QUIC.
- Completely disabling statistics by setting the statistics interval to zero
  ([#2141]).
- The ability to completely purge DHCP leases ([#1691]).

- Configuration file parameters to change group and user ID on startup on Unix
  ([#2763]).
- Experimental OpenBSD support for AMD64 and 64-bit ARM CPUs ([#2439], [#3225],
  [#3226]).
- Support for custom port in DNS-over-HTTPS profiles for Apple's devices
  ([#3172]).
- `darwin/arm64` support ([#2443]).
- `freebsd/arm64` support ([#2441]).
- Output of the default addresses of the upstreams used for resolving PTRs for
  private addresses ([#3136]).
- Detection and handling of recurrent PTR requests for locally-served addresses
  ([#3185]).
- The ability to completely disable reverse DNS resolving of IPs from
  locally-served networks ([#3184]).
- New flag `--local-frontend` to serve dynamically changeable frontend files
  from disk as opposed to the ones that were compiled into the binary.

### Changed

- Port bindings are now checked for uniqueness ([#3835]).
- The DNSSEC check now simply checks against the AD flag in the response
  ([#3904]).
- Client objects in the configuration file are now sorted ([#3933]).
- Responses from cache are now labeled ([#3772]).
- Better error message for ED25519 private keys, which are not widely supported
  ([#3737]).
- Cache now follows RFC more closely for negative answers ([#3707]).
- `$dnsrewrite` rules and other DNS rewrites will now be applied even when the
  protection is disabled ([#1558]).
- DHCP gateway address, subnet mask, IP address range, and leases validations
  ([#3529]).
- The `systemd` service script will now create the `/var/log` directory when it
  doesn't exist ([#3579]).
- Items in allowed clients, disallowed clients, and blocked hosts lists are now
  required to be unique ([#3419]).
- The TLS private key previously saved as a string isn't shown in API responses
  anymore ([#1898]).
- Better OpenWrt detection ([#3435]).
- DNS-over-HTTPS queries that come from HTTP proxies in the `trusted_proxies`
  list now use the real IP address of the client instead of the address of the
  proxy ([#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.
- Query log search now supports internationalized domains ([#3012]).
- Internationalized domains are now shown decoded in the query log with the
  original encoded version shown in request details ([#3013]).
- When /etc/hosts-type rules have several IPs for one host, all IPs are now
  returned instead of only the first one ([#1381]).
- The setting `rlimit_nofile` is now in the `os` block of the configuration
  file, together with the new `group` and `user` settings ([#2763]).
- Permissions on filter files are now `0o644` instead of `0o600` ([#3198]).

#### Configuration Changes

In this release, the schema version has changed from 10 to 12.

- Parameter `dns.querylog_interval`, which in schema versions 11 and earlier
  used to be an integer number of days, is now a string with a human-readable
  duration:

  ```yaml
  # BEFORE:
  'dns':
    # …
    'querylog_interval': 90

  # AFTER:
  'dns':
    # …
    'querylog_interval': '2160h'
  ```

  To rollback this change, convert the parameter back into days and change the
  `schema_version` back to `11`.

- Parameter `rlimit_nofile`, which in schema versions 10 and earlier used to be
  on the top level, is now moved to the new `os` object:

  ```yaml
  # BEFORE:
  'rlimit_nofile': 42

  # AFTER:
  'os':
    'group': ''
    'rlimit_nofile': 42
    'user': ''
  ```

  To rollback this change, move the parameter on the top level and change the
  `schema_version` back to `10`.

### Deprecated

- Go 1.16 support.  v0.108.0 will require at least Go 1.17 to build.

- Rules with the `$denyallow` modifier applying to IP addresses when they
  shouldn't ([#3175]).

  `/etc/network/interfaces` ([#2302]).
- DNSCrypt protocol support ([#1361]).
- A 5 second wait period until a DHCP server's network interface gets an IP
  address ([#2304]).
- `$dnstype` modifier for filters ([#2337]).
- HTTP API request body size limit ([#2305]).

### Changed

- `Access-Control-Allow-Origin` is now only set to the same origin as the
  domain, but with an HTTP scheme as opposed to `*` ([#2484]).
- `workDir` now supports symlinks.
- Stopped mounting together the directories `/opt/adguardhome/conf` and
  `/opt/adguardhome/work` in our Docker images ([#2589]).
- When `dns.bogus_nxdomain` option is used, the server will now transform
  responses if there is at least one bogus address instead of all of them
  ([#2394]).  The new behavior is the same as in `dnsmasq`.
- Post-updating relaunch possibility is now determined OS-dependently ([#2231],
  [#2391]).
- Made the mobileconfig HTTP API more robust and predictable, add parameters and
  improve error response ([#2358]).
- Improved HTTP requests handling and timeouts ([#2343]).
- Our snap package now uses the `core20` image as its base ([#2306]).
- New build system and various internal improvements ([#2271], [#2276], [#2297],
  [#2509], [#2552], [#2639], [#2646]).

### Deprecated

- Go 1.14 support.  v0.106.0 will require at least Go 1.15 to build.
- The `darwin/386` port.  It will be removed in v0.106.0.
- The `"rule"` and `"filter_id"` fields in `GET /filtering/check_host` and
  `GET /querylog` responses.  They will be removed in v0.106.0 ([#2102]).

### Fixed

- Autoupdate bug in the Darwin (macOS) version ([#2630]).
- Unnecessary conversions from `string` to `net.IP`, and vice versa ([#2508]).
- Inability to set DNS cache TTL limits ([#2459]).
- Possible freezes on slower machines ([#2225]).
- A mitigation against records being shown in the wrong order on the query log
  page ([#2293]).
- A JSON parsing error in query log ([#2345]).
- Incorrect detection of the IPv6 address of an interface as well as another
  infinite loop in the `/dhcp/find_active_dhcp` HTTP API ([#2355]).

### Removed

- The undocumented ability to use hostnames as any of `bind_host` values in
  configuration.  Documentation requires them to be valid IP addresses, and now
  the implementation makes sure that that is the case ([#2508]).
- `Dockerfile` ([#2276]).  Replaced with the script
  `scripts/make/build-docker.sh` which uses `scripts/make/Dockerfile`.
- Support for pre-v0.99.3 format of query logs ([#2102]).
