AdGuardHome/CHANGELOG.md

AdGuard Home Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

• IPv6 support in Safe Search for some services.
• The ability to make bootstrap DNS lookups prefer IPv6 addresses to IPv4 ones using the new dns.bootstrap_prefer_ipv6 configuration file property (#4262).
• Docker container's healthcheck (#3290).
• The new HTTP API POST /control/protection, that updates protection state and adds an optional pause duration (#1333). The format of request body is described in openapi/openapi.yaml. The duration of this pause could also be set with the config field protection_disabled_until in dns section of the YAML configuration file.
• The ability to create a static DHCP lease from a dynamic one more easily (#3459).
• Two new HTTP APIs, PUT /control/stats/config/update and GET control/stats/config, which can be used to set and receive the query log configuration. See openapi/openapi.yaml for the full description.
• Two new HTTP APIs, PUT /control/querylog/config/update and GET control/querylog/config, which can be used to set and receive the statistics configuration. See openapi/openapi.yaml for the full description.
• The ability to set custom IP for EDNS Client Subnet by using the DNS-server configuration section on the DNS settings page in the UI (#1472).
• The ability to manage safesearch for each service by using the new safe_search field (#1163).

Changed

• ARPA domain names containing a subnet within private networks now also considered private, behaving closer to RFC 6761 (#5567).

Configuration Changes

In this release, the schema version has changed from 17 to 20.

• Property statistics.interval, which in schema versions 19 and earlier used to be an integer number of days, is now a string with a human-readable duration:

  # BEFORE:
  'statistics':
    # …
    'interval': 1
  
  # AFTER:
  'statistics':
    # …
    'interval': '24h'
  

  To rollback this change, convert the property back into days and change the schema_version back to 19.

• The dns.safesearch_enabled field has been replaced with safe_search object containing per-service settings.

• The clients.persistent.safesearch_enabled field has been replaced with safe_search object containing per-service settings.

    # BEFORE:
    'safesearch_enabled': true
  
    # AFTER:
    'safe_search':
      'enabled': true
      'bing': true
      'duckduckgo': true
      'google': true
      'pixabay': true
      'yandex': true
      'youtube': true
  

  To rollback this change, move the value of dns.safe_search.enabled into the dns.safesearch_enabled, then remove dns.safe_search field. Do the same client's specific clients.persistent.safesearch and then change the schema_version back to 17.

Deprecated

• The POST /control/safesearch/enable HTTP API is deprecated. Use the new PUT /control/safesearch/settings API.

• The POST /control/safesearch/disable HTTP API is deprecated. Use the new PUT /control/safesearch/settings API

• The safesearch_enabled field is deprecated in the following HTTP APIs:

  • GET /control/clients;
  • POST /control/clients/add;
  • POST /control/clients/update;
  • GET /control/clients/find?ip0=...&ip1=...&ip2=....

  Check openapi/openapi.yaml for more details.

• The GET /control/stats_info HTTP API; use the new GET /control/stats/config API instead.

  NOTE: If interval is custom then it will be equal to 90 days for compatibility reasons. See openapi/openapi.yaml and openapi/CHANGELOG.md.

• The POST /control/stats_config HTTP API; use the new PUT /control/stats/config/update API instead.

• The GET /control/querylog_info HTTP API; use the new GET /control/querylog/config API instead.

  NOTE: If interval is custom then it will be equal to 90 days for compatibility reasons. See openapi/openapi.yaml and openapi/CHANGELOG.md.

• The POST /control/querylog_config HTTP API; use the new PUT /control/querylog/config/update API instead.

v0.107.27 - 2023-04-05

See also the v0.107.27 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2023-24534, CVE-2023-24536, CVE-2023-24537, and CVE-2023-24538 Go vulnerabilities fixed in Go 1.19.8.

Fixed

• Query log not showing all filtered queries when the “Filtered” log filter is selected (#5639).
• Panic in empty hostname in the filter's URL (#5631).
• Panic caused by empty top-level domain name label in /etc/hosts files (#5584).

v0.107.26 - 2023-03-09

See also the v0.107.26 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2023-24532 Go vulnerability fixed in Go 1.19.7.

Added

• The ability to set custom IP for EDNS Client Subnet by using the new dns.edns_client_subnet.use_custom and dns.edns_client_subnet.custom_ip fields (#1472). The UI changes are coming in the upcoming releases.
• The ability to use dnstype rules in the disallowed domains list (#5468). This allows dropping requests based on their question types.

Changed

Configuration Changes

• Property edns_client_subnet, which in schema versions 16 and earlier used to be a part of the dns object, is now part of the dns.edns_client_subnet object:

  # BEFORE:
  'dns':
    # …
    'edns_client_subnet': false
  
  # AFTER:
  'dns':
    # …
    'edns_client_subnet':
      'enabled': false
      'use_custom': false
      'custom_ip': ''
  

  To rollback this change, move the value of dns.edns_client_subnet.enabled into the dns.edns_client_subnet, remove the fields dns.edns_client_subnet.enabled, dns.edns_client_subnet.use_custom, dns.edns_client_subnet.custom_ip, and change the schema_version back to 16.

Fixed

• Obsolete value of the Interface MTU DHCP option is now omitted (#5281).

v0.107.24 - 2023-02-15

See also the v0.107.24 GitHub milestone.

Security

• Go version has been updated, both because Go 1.18 has reached end of life an to prevent the possibility of exploiting the Go vulnerabilities fixed in Go 1.19.6.

Added

• The ability to disable statistics by using the new statistics.enabled field. Previously it was necessary to set the statistics_interval to 0, losing the previous value (#1717, #4299).
• The ability to exclude domain names from the query log or statistics by using the new querylog.ignored or statistics.ignored fields (#1717, #4299). The UI changes are coming in the upcoming releases.

Changed

Configuration Changes

In this release, the schema version has changed from 14 to 16.

• Property statistics_interval, which in schema versions 15 and earlier used to be a part of the dns object, is now a part of the statistics object:

  # BEFORE:
  'dns':
    # …
    'statistics_interval': 1
  
  # AFTER:
  'statistics':
    # …
    'interval': 1
  

  To rollback this change, move the property back into the dns object and change the schema_version back to 15.

• The fields dns.querylog_enabled, dns.querylog_file_enabled, dns.querylog_interval, and dns.querylog_size_memory have been moved to the new querylog object.

  # BEFORE:
  'dns':
    'querylog_enabled': true
    'querylog_file_enabled': true
    'querylog_interval': '2160h'
    'querylog_size_memory': 1000
  
  # AFTER:
  'querylog':
    'enabled': true
    'file_enabled': true
    'interval': '2160h'
    'size_memory': 1000
    'ignored': []
  

  To rollback this change, rename and move properties back into the dns object, remove querylog object and querylog.ignored property, and change the schema_version back to 14.

Deprecated

• Go 1.19 support. Future versions will require at least Go 1.20 to build.

Fixed

• Setting the AD (Authenticated Data) flag on responses that have the DO (DNSSEC OK) flag set but not the AD flag (#5479).
• Client names resolved via reverse DNS not being updated (#4939).
• The icon for League Of Legends on the Blocked services page (#5433).

Removed

• Go 1.18 support, as it has reached end of life.

v0.107.23 - 2023-02-01

See also the v0.107.23 GitHub milestone.

Added

• DNS64 support (#5117). The function may be enabled with new use_dns64 field under dns object in the configuration along with dns64_prefixes, the set of exclusion prefixes to filter AAAA responses. The Well-Known Prefix (64:ff9b::/96) is used if no custom prefixes are specified.

Fixed

• Filtering rules with * as the hostname not working properly (#5245).
• Various dark theme bugs (#5375).

Removed

• The “beta frontend” and the corresponding APIs. They never quite worked properly, and the future new version of AdGuard Home API will probably be different.

  Correspondingly, the configuration parameter beta_bind_port has been removed as well.

v0.107.22 - 2023-01-19

See also the v0.107.22 GitHub milestone.

Added

• Experimental Dark UI theme (#613).
• The new HTTP API PUT /control/profile/update, that updates current user language and UI theme. The format of request body is described in openapi/openapi.yaml.

Changed

• The HTTP API GET /control/profile now returns enhanced object with current user's name, language, and UI theme. The format of response body is described in openapi/openapi.yaml and openapi/CHANGELOG.md.

Fixed

• AdGuardHome --update freezing when another instance of AdGuard Home is running (#4223, #5191).
• The --update flag performing an update even when there is no version change.
• Failing HTTPS redirection on saving the encryption settings (#4898).
• Zeroing rules counter of erroneously edited filtering rule lists (#5290).
• Filters updating strategy, which could sometimes lead to use of broken or incompletely downloaded lists (#5258).

v0.107.21 - 2022-12-15

See also the v0.107.21 GitHub milestone.

Changed

• The URLs of the default filters for new installations are synchronized to those introduced in v0.107.20 (#5238).

  NOTE: Some users may need to re-add the lists from the vetted filter lists to update the URLs to the new ones. Custom filters added by users themselves do not require re-adding.

Fixed

• Errors popping up during updates of settings, which could sometimes cause the server to stop responding (#5251).

v0.107.20 - 2022-12-07

See also the v0.107.20 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-41717 and CVE-2022-41720 Go vulnerabilities fixed in Go 1.18.9.

Added

• The ability to clear the DNS cache (#5190).

Changed

• DHCP server initialization errors are now logged at debug level if the server itself disabled (#4944).

Fixed

• Wrong validation error messages on the DHCP configuration page (#5208).
• Slow upstream checks making the API unresponsive (#5193).
• The TLS initialization errors preventing AdGuard Home from starting (#5189). Instead, AdGuard Home disables encryption and shows an error message on the encryption settings page in the UI, which was the intended previous behavior.
• URLs of some vetted blocklists.

v0.107.19 - 2022-11-23

See also the v0.107.19 GitHub milestone.

Added

• The ability to block popular Mastodon instances (AdguardTeam/HostlistsRegistry#100).
• The new --update command-line option, which allows updating AdGuard Home silently (#4223).

Changed

• Minor UI changes.

v0.107.18 - 2022-11-08

See also the v0.107.18 GitHub milestone.

Fixed

• Crash on some systems when domains from system hosts files are processed (#5089).

v0.107.17 - 2022-11-02

See also the v0.107.17 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-41716 Go vulnerability fixed in Go 1.18.8.

Added

• The warning message when adding a certificate having no IP addresses (#4898).
• Several new blockable services (#3972). Those will now be more in sync with the services that are already blockable in AdGuard DNS.
• A new HTTP API, GET /control/blocked_services/all, that lists all available blocked services and their data, such as SVG icons (#3972).
• The new optional tls.override_tls_ciphers property, which allows overriding TLS ciphers used by AdGuard Home (#4925, #4990).
• The ability to serve DNS on link-local IPv6 addresses (#2926).
• The ability to put ClientIDs into DNS-over-HTTPS hostnames as opposed to URL paths (#3418). Note that AdGuard Home checks the server name only if the URL does not contain a ClientID.

Changed

• DNS-over-TLS resolvers aren't returned anymore when the configured TLS certificate contains no IP addresses (#4927).
• Responses with SERVFAIL code are now cached for at least 30 seconds.

Deprecated

• The GET /control/blocked_services/services HTTP API; use the new GET /control/blocked_services/all API instead (#3972).

Fixed

• ClientIDs not working when using DNS-over-HTTPS with HTTP/3.
• Editing the URL of an enabled rule list also includes validation of the filter contents preventing from saving a bad one (#4916).
• The default value of dns.cache_size accidentally set to 0 has now been reverted to 4 MiB (#5010).
• Responses for which the DNSSEC validation had explicitly been omitted aren't cached now (#4942).
• Web UI not switching to HTTP/3 (#4986, #4993).

v0.107.16 - 2022-10-07

This is a security update. There is no GitHub milestone, since no GitHub issues were resolved.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-2879, CVE-2022-2880, and CVE-2022-41715 Go vulnerabilities fixed in Go 1.18.7.

v0.107.15 - 2022-10-03

See also the v0.107.15 GitHub milestone.

Security

• As an additional CSRF protection measure, AdGuard Home now ensures that requests that change its state but have no body (such as POST /control/stats_reset requests) do not have a Content-Type header set on them (#4970).

Added

Experimental HTTP/3 Support

See #3955 and the related issues for more details. These features are still experimental and may break or change in the future.

• DNS-over-HTTP/3 DNS and web UI client request support. This feature must be explicitly enabled by setting the new property dns.serve_http3 in the configuration file to true.
• DNS-over-HTTP upstreams can now upgrade to HTTP/3 if the new configuration file property dns.use_http3_upstreams is set to true.
• Upstreams with forced DNS-over-HTTP/3 and no fallback to prior HTTP versions using the h3:// scheme.

Fixed

• User-specific blocked services not applying correctly (#4945, #4982, #4983).
• only application/json is allowed errors in various APIs (#4970).

v0.107.14 - 2022-09-29

See also the v0.107.14 GitHub milestone.

Security

A Cross-Site Request Forgery (CSRF) vulnerability has been discovered. We thank Daniel Elkabes from Mend.io for reporting this vulnerability to us. This is CVE-2022-32175.

SameSite Policy

The SameSite policy on the AdGuard Home session cookies is now set to Lax. Which means that the only cross-site HTTP request for which the browser is allowed to send the session cookie is navigating to the AdGuard Home domain.

Users are strongly advised to log out, clear browser cache, and log in again after updating.

Removal Of Plain-Text APIs (BREAKING API CHANGE)

We have implemented several measures to prevent such vulnerabilities in the future, but some of these measures break backwards compatibility for the sake of better protection.

The following APIs, which previously accepted or returned text/plain data, now accept or return data as JSON. All new formats for the request and response bodies are documented in openapi/openapi.yaml and openapi/CHANGELOG.md.

• GET /control/i18n/current_language;
• POST /control/dhcp/find_active_dhcp;
• POST /control/filtering/set_rules;
• POST /control/i18n/change_language.

Stricter Content-Type Checks (BREAKING API CHANGE)

All JSON APIs that expect a body now check if the request actually has Content-Type set to application/json.

Other Security Changes

• Weaker cipher suites that use the CBC (cipher block chaining) mode of operation have been disabled (#2993).

Added

• Support for plain (unencrypted) HTTP/2 (#4930). This is useful for AdGuard Home installations behind a reverse proxy.

Fixed

• Incorrect path template in DDR responses (#4927).

v0.107.13 - 2022-09-14

See also the v0.107.13 GitHub milestone.

Added

• The new optional dns.ipset_file property, which can be set in the configuration file. It allows loading the ipset list from a file, just like dns.upstream_dns_file does for upstream servers (#4686).

Changed

• The minimum DHCP message size is reassigned back to BOOTP's constraint of 300 bytes (#4904).

Fixed

• Panic when adding a static lease within the disabled DHCP server (#4722).

v0.107.12 - 2022-09-07

See also the v0.107.12 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-27664 and CVE-2022-32190 Go vulnerabilities fixed in Go 1.18.6.

Added

• New bool, dur, u8, and u16 DHCP options to provide more convenience on options control by setting values in a human-readable format (#4705). See also a Wiki page.

• New del DHCP option which removes the corresponding option from server's response (#4337). See also a Wiki page.

  NOTE: This modifier affects all the parameters in the response and not only the requested ones.

• A new HTTP API, GET /control/blocked_services/services, that lists all available blocked services (#4535).

Changed

• The DHCP options handling is now closer to the RFC 2131 (#4705).
• When the DHCP server is enabled, queries for domain names under dhcp.local_domain_name not pointing to real DHCP client hostnames are now processed by filters (#4865).
• The DHCPREQUEST handling is now closer to the RFC 2131 (#4863).
• The internal DNS client, used to resolve hostnames of external clients and also during automatic updates, now respects the upstream mode settings for the main DNS client (#4403).

Deprecated

• Ports 784 and 8853 for DNS-over-QUIC in Docker images. Users who still serve DoQ on these ports are encouraged to move to the standard port 853. These ports will be removed from the EXPOSE section of our Dockerfile in a future release.
• Go 1.18 support. Future versions will require at least Go 1.19 to build.

Fixed

• The length of the DHCP server's response is now at least 576 bytes as per RFC 2131 recommendation (#4337).
• Dynamic leases created with empty hostnames (#4745).
• Unnecessary logging of non-critical statistics errors (#4850).

v0.107.11 - 2022-08-19

Added

• Arabic localization.
• Support for Discovery of Designated Resolvers (DDR) according to the RFC draft (#4463).

Changed

• Our snap package now uses the core22 image as its base (#4843).

Fixed

• DHCP not working on most OSes (#4836).
• invalid argument errors during update checks on older Linux kernels (#4670).
• Data races and concurrent map access in statistics module (#4358, #4342).

v0.107.9 - 2022-08-03

See also the v0.107.9 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-32189 Go vulnerability fixed in Go 1.18.5. Go 1.17 support has also been removed, as it has reached end of life and will not receive security updates.

Added

• Domain-specific upstream servers test. If such test fails, a warning message is shown (#4517).
• windows/arm64 support (#3057).

Changed

• UI and update links have been changed to make them more resistant to DNS blocking.

Fixed

• DHCP not working on most OSes (#4836).
• Several UI issues (#4775, #4776, #4782).

Removed

• Go 1.17 support, as it has reached end of life.

v0.107.8 - 2022-07-13

See also the v0.107.8 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-1705, CVE-2022-32148, CVE-2022-30631, and other Go vulnerabilities fixed in Go 1.17.12.

Fixed

• DHCP lease validation incorrectly letting users assign the IP address of the gateway as the address of the lease (#4698).
• Updater no longer expects a hardcoded name for AdGuardHome executable (#4219).
• Inconsistent names of runtime clients from hosts files (#4683).
• PTR requests for addresses leased by DHCP will now be resolved into hostnames under dhcp.local_domain_name (#4699).
• Broken service installation on OpenWrt (#4677).

v0.107.7 - 2022-06-06

See also the v0.107.7 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-29526, CVE-2022-30634, CVE-2022-30629, CVE-2022-30580, and CVE-2022-29804 Go vulnerabilities.
• Enforced password strength policy (#3503).

Added

• Support for the final DNS-over-QUIC standard, RFC 9250 (#4592).
• Support upstreams for subdomains of a domain only (#4503).
• The ability to control each source of runtime clients separately via clients.runtime_sources configuration object (#3020).
• The ability to customize the set of networks that are considered private through the new dns.private_networks property in the configuration file (#3142).
• EDNS Client-Subnet information in the request details section of a query log record (#3978).
• Support for hostnames for plain UDP upstream servers using the udp:// scheme (#4166).
• Logs are now collected by default on FreeBSD and OpenBSD when AdGuard Home is installed as a service (#4213).

Changed

• On OpenBSD, the daemon script now uses the recommended /bin/ksh shell instead of the /bin/sh one (#4533). To apply this change, backup your data and run AdGuardHome -s uninstall && AdGuardHome -s install.

• The default DNS-over-QUIC port number is now 853 instead of 754 in accordance with RFC 9250 (#4276).

• Reverse DNS now has a greater priority as the source of runtime clients' information than ARP neighborhood.

• Improved detection of runtime clients through more resilient ARP processing (#3597).

• The TTL of responses served from the optimistic cache is now lowered to 10 seconds.

• Domain-specific private reverse DNS upstream servers are now validated to allow only *.in-addr.arpa and *.ip6.arpa domains pointing to locally-served networks (#3381).

  NOTE: If you already have invalid entries in your configuration, consider removing them manually, since they essentially had no effect.

• Response filtering is now performed using the record types of the answer section of messages as opposed to the type of the question (#4238).

• Instead of adding the build time information, the build scripts now use the standardized environment variable SOURCE_DATE_EPOCH to add the date of the commit from which the binary was built (#4221). This should simplify reproducible builds for package maintainers and those who compile their own AdGuard Home.

• The property local_domain_name is now in the dhcp object in the configuration file to avoid confusion (#3367).

• The dns.bogus_nxdomain property in the configuration file now supports CIDR notation alongside IP addresses (#1730).

Configuration Changes

In this release, the schema version has changed from 12 to 14.

• Object clients, which in schema versions 13 and earlier was an array of actual persistent clients, is now consist of persistent and runtime_sources properties:

  # BEFORE:
  'clients':
  - name: client-name
    # …
  
  # AFTER:
  'clients':
    'persistent':
      - name: client-name
        # …
    'runtime_sources':
      whois: true
      arp: true
      rdns: true
      dhcp: true
      hosts: true
  

  The value for clients.runtime_sources.rdns field is taken from dns.resolve_clients property. To rollback this change, remove the runtime_sources property, move the contents of persistent into the clients itself, the value of clients.runtime_sources.rdns into the dns.resolve_clients, and change the schema_version back to 13.

• Property local_domain_name, which in schema versions 12 and earlier used to be a part of the dns object, is now a part of the dhcp object:

  # BEFORE:
  'dns':
    # …
    'local_domain_name': 'lan'
  
  # AFTER:
  'dhcp':
    # …
    'local_domain_name': 'lan'
  

  To rollback this change, move the property back into the dns object and change the schema_version back to 12.

Deprecated

• The --no-etc-hosts option. Its functionality is now controlled by clients.runtime_sources.hosts configuration property. v0.109.0 will remove the flag completely.

Fixed

• Query log occasionally going into an infinite loop (#4591).
• Service startup on boot on systems using SysV-init (#4480).
• Detection of the stopped service status on macOS and Linux (#4273).
• Case-sensitive ClientID (#4542).
• Slow version update queries making other HTTP APIs unresponsive (#4499).
• ARP tables refreshing process causing excessive PTR requests (#3157).

v0.107.6 - 2022-04-13

See also the v0.107.6 GitHub milestone.

Security

• User-Agent HTTP header removed from outgoing DNS-over-HTTPS requests.
• Go version has been updated to prevent the possibility of exploiting the CVE-2022-24675, CVE-2022-27536, and CVE-2022-28327 Go vulnerabilities.

Added

• Support for SVCB/HTTPS parameter dohpath in filtering rules with the dnsrewrite modifier according to the RFC draft (#4463).

Changed

• Filtering rules with the dnsrewrite modifier that create SVCB or HTTPS responses should use ech instead of echconfig to conform with the latest drafts.

Deprecated

• SVCB/HTTPS parameter name echconfig in filtering rules with the dnsrewrite modifier. Use ech instead. v0.109.0 will remove support for the outdated name echconfig.
• Obsolete --no-mem-optimization option (#4437). v0.109.0 will remove the flag completely.

Fixed

• I/O timeout errors when checking for the presence of another DHCP server.
• Network interfaces being incorrectly labeled as down during installation.
• Rules for blocking the QQ service (#3717).

Removed

• Go 1.16 support, since that branch of the Go compiler has reached end of life and doesn't receive security updates anymore.

v0.107.5 - 2022-03-04

  # BEFORE:
  'rlimit_nofile': 42
  
  # AFTER:
  'os':
    'group': ''
    'rlimit_nofile': 42
