版本历史 | AdGuard

Windows 用户会对本次 AdGuard Home 更新特别感兴趣。我们针对 Windows 进行了必要的安全改进。不过，AdGuard Home 更新能满足每个人的需求，而不仅仅是 Windows 用户。现在，过滤器性能更好。当然，我们还修复了一些其他错误。

我们将 AdGuard Home 的更新推迟了几个月。当然，我们有充分的理由：我们在社区成员的帮助下（非常感谢大家！🙏），发现了两个错误，因此，我们一直在努力修复它们。测试解决方案的时间比预期要长一些，但最终，我们相信质量胜于速度。

本次更新不仅仅是修补漏洞和修复错误，我们还做了一些改进。例如，我们在「安全搜索」功能中添加了对 64 位 RISC-V 架构和 Ecosia 搜索引擎的支持。完整的更新日志如下。

在此更新中，我们修复了许多错误，将前端迁移到了 TypeScript，并更新了前端库，以提高开发质量和用户体验。

这次更新我们修复了错误并改进了安全。我们在开发即将发布版本的新功能。

我们发布此修复程序的原因是，上次 AdGuard Home 更新后，一些用户无法启动 AdGuard Home。

在这次补丁中，我们修复了一些错误，让 AdGuard Home 运行更流畅。

上次更新后，被禁止的用户可以使用加密协议执行 DNS 查询。这是一个错误，我们已修复了它。

我们对这一疏忽表示诚挚的歉意。我们将尽一切努力确保今后不再发生此类错误。

这是另一个与安全相关的错误修复更新。我们修复了时区选择问题和其他一些恼人的错误。

在更新版本中，我们修复错误并改进性能 🔧

这是一个小更新，包含安全改进、错误修复和新功能。

最大的变化往往是最不被人所注意到的 —— 我们今天的更新就是如此。我们为齿轮“上油“了，进行了重要改进和各种错误修复 🔧。

Everybody needs something to keep themselves warm during the cold winter days ❄️. Many people opt for hot coffee ☕ or hot chocolate, but we at AdGuard prefer hotfixes 🔥.

As the winter holidays approach, many of us begin to think about what gifts we will give and receive 🎁. With AdGuard, the holidays come early: we decided not to wait too long and present you with this new version of AdGuard Home today!

Among the long-awaited features in this release are the option to enable caching for persistent clients with custom DNS upstream configuration and the option to disable plain DNS for better security.

四季交替，但不同的 Bug 却总出现 📆 不过，在此版本中，我们不仅修复了许多 Bug 错误，还添加了一些功能，使 AdGuard Home 的配置更简单，并保护其免受 DDoS 攻击！

还有什么比阻挡您上网的错误更可怕的呢？幸运的是，我们推出热修复程序以解决所有错误！

我们继续改善 AdGuard Home！在这次更新中，我们添加了一些新功能，修复了错误。

新版本就像水果一样：苹果越美味就越容易招来虫子（Bug 错误）。从这个意义上说，前一个版本似乎非常“美味” ，而我们在这次发布的热修复中修复了剩余的错误。

夏天悄悄地溜走了，但我们还是收获了期待已久的功能和改进，以及错误修复！

服务拦截的暂停时间

现在，用户可以一键设置服务拦截过滤器的暂停时间。比如说，在设置中在全天内拦截社交媒体，但是下班后给自己30分钟刷抖音的时间。

这项功能已经在内部开发了几个月，终于可以在这个版本的网页用户界面中使用了！

后备服务器

另一个大家期待已久的功能是，首选上游 DNS 服务器无响应时使用的后备服务器。

后备服务器的语法与首选上游的输入相同，因此用户可以为不同的域名设置不同的后备服务器。

上游的统计数据

与 DNS 上游相关的另一项功能是，在仪表板上显示新的上游统计数据。

新功能让用户查看哪一个上游服务器是速度最快的，哪一个上游服务器使用数量最多的。

致谢

特别感谢我们的开源贡献者 @ssrahul96，以及所有提交和检查问题、添加翻译并帮助我们测试此版本的人！

这次更新我们修复了错误并改进了安全。我们在开发即将发布版本的新功能。

In the previous release, we optimized the filtering-rule list updates, achieving up to three times speedup in some cases. However, the new algorithm proved to be too strict, so in this release we have relaxed its validations while maintaining the optimization for more typical filtering-rule lists 🏎️

As always, there are other minor bug fixes in this release as well.

在这次更新中，我们改进了 AdGuard Home 的安全性，并修复了错误。

安全浏览和 CPU 跳跃

6月，我们发布了 AdGuard Home 的安全性以及错误修复的更新。讽刺的是，更新带来了另一个错误。发布上次更新后，「安全浏览」和「家长控制」就无法正常运作，这在某些情况下导致性能下降、随机崩溃和巨大的 CPU 跳跃。

我们花了整整一个月的时间才弄清楚本问题，如果没有社区成员，包括 @bigwookie、 @TheCableGuy99 和其他人的帮助，我们肯定会花更长的时间解决该问题。事实证明，重大错误实际上是由三个小错误一起造成的。在这次更新中，我们处理好了这些错误。

Docker `HEALTHCHECK`

Docker 用户应该注意到，Docker 的 HEALTHCHECK 机制已经被移除，因为它会导致很多问题，特别是在与 Podman 和其他流行的 Docker 工具一起使用时。

感谢

特别感谢我们的开源贡献者 @Jiraiya8，以及所有提交和检查问题、添加翻译和帮助我们测试此版本的人！

这次是一个错误修复的更新🔧。此外，我们正在进行内部改进，以方便在未来版本中增加新的功能。

热修复，修复了以前版本的错误。

热修复，我们修复了以前版本的两个主要错误。

这次更新我们修复了错误并改进了安全。我们在开发即将发布版本的新功能。

载人空间飞行国际日我们发布了上次更新，但我们的航天器，即 AdGuard Home，的发射出现了一些问题。在这次更新，我们修复了一些让人讨厌的 Bug，并改进了客户端的忽略功能。

我们终于发布一个包含大量新功能的更新。在这些功能中，我们想提到一些用户期待了很久的改进。

全面保护的暂停

首先，现在有一种方法可以在设定的时间段内暂停保护，从30秒到一整天。当用户需要访问一个被错误屏蔽的网站或想暂时禁用 AdGuard Home 而不完全关闭它时，这是一个很好用的功能。 Screenshot from 2023-04-12 14-06-17

一旦暂停时间结束，AdGuard Home 将重新开启保护。

更好的「安全搜索」管理

其次，用户现在可以通过启用或禁用 Google、Bing、YouTube 等特定服务来微调「安全搜索」设置。 Screenshot from 2023-04-12 14-10-55

同样的操作也可以在单个客户层面上进行。此外，我们还改进了对 IPv6 地址的支持。

这次更新我们修复了一些错误。此外，我们更新了 Go 计算机编程语言的版本。下一个更新将包含更多改进。

今天的更新包括，配置发出请求的和一个基于其类型拒绝请求的新选项，并且我们还修复了很多错误。

这次的热补丁更新防止在使用未加密的 DNS-over-HTTPS 时出现致命的错误，在反向 HTTP 代理后配置 AdGuard Home 的用户遇到了这些错误。

在 AdGuard Home 的新版本我们增加了一种在查询日志和统计信息屏幕上排除特定主机名的方法。这样用户可以更加方便地指定不想阻止的主机名。

字体! 颜色! 按钮! 每个用户都喜欢讨论用户界面设计，但我们更喜欢为我们的亲爱的用户们修复错误，并添加新功能🚢。除了黑暗模式的调整，这次版本还包括对 DNS64 的支持、几个新的可拦截的服务，以及一些错误修复和内部改进。

漫长的夜晚，没有人喜欢的一件事是，用户界面太亮了，字体都看不清楚🔦。这次更新，AdGuard Home 终于应用了用户最常要求的功能之一，即黑暗模式！

新的黑暗模式仍是实验性的，显得比较粗糙。如果您想报告错误，请按照问题#5375中的说明报告错误。

让冬天更温暖的热修复。

当在世界杯上足球守门员尽力守门，保证球门安全时，我们也尽一切努力保证我们用户的隐私安全，随时发布更新🛡️ 此外，我们还增加了一个按钮让用户轻松清除 DNS 缓存。

您可能发现自己使用社交媒体“过量”了，但现代人难以远离社交媒体。好吧，我们难以远离它们，但感谢 @sandervankasteel ，现在“逃离”社交媒体可以成为生活的一部分了：AdGuard Home 可以拦截流行 Mastodon 实例。休息一下，别再刷网页了，留一部分有意义的时间独处、阅读和成长吧！

除此之外，我们添加了 --update 命令行。现在，一键就可以更新 AdGuard Home。

Despite this release appearing around Halloween, it shouldn't be spooky at all. The main novelty is that the list of services blockable with a single click is now synchronized with AdGuard DNS to make the user experience more unified across AdGuard services. We've also improved support for HTTP/3 as well as fixed a few annoying bugs.

This is a security release. There are no new changes besides the update of the Go programming language version. More substantial changes are to come in the subsequent updates.

Full Changelog

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.

Sometimes, even a hotfix needs a hotfix. In the previous release, our mitigations turned out to be too restrictive, preventing some AdGuard Home features from working properly. In this release, we fix this along with a few other bugs.

We have also added experimental support for the HTTP/3 standard in the UI, DNS upstreams, and DNS clients!

Full Changelog

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.

This is a security release. Users are encouraged to update AdGuard Home as soon as possible.

Full Changelog

Security

A Cross-Site Request Forgery (CSRF) vulnerability has been discovered. The CVE number is to be assigned. We thank Daniel Elkabes from Mend for reporting this vulnerability to us.

SameSite Policy

The SameSite policy on the AdGuard Home session cookies has been upgraded 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 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.

In this hotfix release with the “lucky” patch number we have fixed a couple of issues that prevented some DHCP clients from receiving their assigned IP addresses. We've also added the new dns.ipset_file setting, which should help users who maintain large ipsets, for example to use in firewall or VPN settings.

Full Changelog

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.

What better way is there to celebrate the coming of autumn than a patch release? In this new version, we have extended and significantly improved AdGuard Home's built-in DHCP server (fixing many bugs in the process) as well as improved our service blocking feature, thanks to many contributions from the community. As always, we have also updated our tooling to make sure that we use the latest versions without any known security issues.

Full Changelog

Security

Go version was 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][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.

This hot summer is approaching its end, but hotfixes are still coming in! In this release, we have fixed configuration file migrations not working for people with AdGuard Home versions older than v0.107.7, as well as made a few minor improvements.

Full Changelog

--

Added

Bilibili service blocking #4795.

Changed

DNS-over-QUIC connections now use keepalive.

Fixed

Migrations from releases older than v0.107.7 failing #4846.

In this new release, we add support for the new Discovery of Designated Resolvers DDR feature, which allows clients using plain DNS to automatically switch to secure protocols. As well as an Arabic localization and fixes for a couple of rather annoying bugs.

Full Changelog

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 OSs #4836.

invalid argument errors during update checks on older Linux kernels #4670.

Data races and concurrent map access in statistics module #4358, #4342.

Although not a lot of time has passed since the last release, this new one contains a security update, a new feature, a new platform, and some minor fixes :wrench:. It's always nice to have those!

Full Changelog

Security

Go version was 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

Several UI issues #4775, #4776, #4782.

Removed

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

孔子说，人非圣贤孰能无过。因此，我们要积极面对自己的错误，并改成它。而这正是我们发现了错误修复版本之后做的第一件事情。

更新日志

安全

Go 版本已更新，以防止利用 CVE-2022-1705、CVE-2022-32148、CVE-2022-30631 和其他在 [Go 1.17.12] 中修复的 Go 漏洞的可能性(https://groups.google.com/g/golang-announce/c/nqrv9fbR0zE)。

修复

DHCP 租约验证不正确地让用户将网关的 IP 地址指定为租约的地址 #4698.

更新器不再等待 AdGuardHome 可执行文件的硬编码名称#4219。

来自 hosts 文件的运行时客户端的名称不一致 #4683。

由 DHCP 租赁的地址的 PTR 请求现在将被解析为 dhcp.local_domain_name 下的主机名 #4699.

OpenWrt 上的服务安装中断 #4677.

这个夏季我们给大家带来了 AdGuard Home 的新版本！

DNS-over-QUIC：RFC 9250

等待已久的 DNS-over-QUIC 协议终于改进了，成为了正式标准版本，RFC 9250。这次更新，我们以向后兼容的方式添加了正式版本的支持。

对上游的更多管控

现在，用户可以指定每一个网域的子网域的上游，同时排除网域本身。比方说，如用户想要把 server-1.example.com 查询由 1.1.1.1 的 DNS 服务器解析，但是把 example.com 依然由默认上游（在这种情况下，是 94.140.14.14）解析，那么您需要使用：

94.140.14.14
[/*.example.com/]1.1.1.1

说到上游，现在用户无须记得无加密 DNS 上游的 IP 地址。Bootstrap 服务器就能够解析它们，您就可以使用新的 udp:// 上游地址方案来自动解析上游的地址。

udp://one.one.one.one # Same as 1.1.1.1.

其他重要更新

现在，用户对如何收集运行时客户端信息有了更多的控制，包括完全禁用这一功能的选择。

来自客户请求的 EDNS 客户子网信息现显示于查询日志页上。

像往常一样，我们努力保持我们的工具与时俱进，以确保我们给用户们提供的安全网没有漏洞。

此外，还有更多小的改进。您可以查看更新日志了解所有改进！

致谢

特别感谢我们的开源贡献者，@Lanius-collaris，以及所有提交和检查问题、添加翻译和帮助我们测试这个版本的客户。

更新日志

安全

Go 版本已经更新了以防止可能被利用
CVE-2022-29526, CVE-2022-30634, CVE-2022-30629, CVE-2022-30580，以及 CVE-2022-29804 的弱点。

强制执行的密码强度策略#3503.

添加的功能

对 DNS-over-QUIC 标准版的支持，（RFC 9250）#4592.

只支持一个域的子域的上游 #4503.

能够通过 clients.runtime_sources 配置单独控制每个运行时客户端的来源 #3020.

通过配置文件中新的dns.private_networks属性，能够定制被认为是私有的网络集 #3142.

在查询日志记录的请求细节部分的 EDNS 客户子网信息 #3978.

支持使用udp://方案的普通UDP上游服务器的主机名 #4166.

在 FreeBSD 和 OpenBSD 上，当 AdGuard Home 以服务形式安装时，现在默认会收集日志 #4213.

改进

在 OpenBSD 上，认识系统服务脚本现在使用推荐的 /bin/ksh shell，而不是 /bin/sh #4533。要应用这一变化，请备份您的数据并运行 AdGuardHome -s uninstall && AdGuardHome -s install。

根据(RFC 9250)，默认的 DNS-over-QUIC 端口号现在是 853 而不是 754#4276.

反向 DNS 现在作为运行时客户的信息来源，比 ARP 具有更大的优先权。

通过更有弹性的 ARP 处理，改进对正在运行的客户的检测 #3597.

从乐观缓存提供的响应的TTL现在被降低到10秒。

特定域的私有反向 DNS 上游服务器现在被验证为只允许 *.in-addr.arpa 和 *.ip6.arpa 域指向本地服务的网络#3381。注意：如果你的配置中已经有无效的条目，请考虑手动删除它们，因为它们基本上没有作用。

响应过滤现在使用信息回答部分的记录类型来执行，而不是问题的类型。#4238.

现在，构建脚本不再需要添加构建时间信息，而是使用标准化的环境变量 [SOURCE_DATE_EPOCH][repr] 来添加构建二进制文件的提交日期 #4221 。这应该可以简化软件包维护者和那些编译自己的AdGuard Home的人的可重复构建过程。

属性 local_domain_name 现在在配置文件的 dhcp 对象中，以避免混淆#3367。

配置文件中的 dns.bogus_nxdomain 属性现在支持CIDR符号和 IP 地址#1730.

配置改进

在这个版本中，模式的版本已经从12变成了14。

对象 clients，在模式 13 和更早的版本中是一个实际持久性客户的数组，现在是由 persistent 和 runtime_sources 属性组成。

# BEFORE:
'clients':
- name: client-name
  # …

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

clients.runtime_sources.rdns 字段的值取自 dns.resolve_clients 属性。要撤销这一变化，请删除 runtime_sources 属性，将 persistent 的内容移入 clients 本身，将clients.runtime_sources.rdns的值移入dns.resolve_clients，并将 schema_version 改回 13。

属性 local_domain_name，在模式12和更早的版本中曾经是 dns 对象的一部分，现在是 dhcp 对象的一部分。

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

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

要撤销这一变化，将该属性移回 dns 对象，并将 schema_version 改回 12。

修改

--no-etc-hosts选项。它的功能现在由 "clients.runtime_sources.hosts "配置属性控制。

修复

查询日志偶尔会进入一个无限循环 #4591.

在使用 SysV-init 的系统上启动服务#4480.

检测 MacOS 和 Linux 上停止的服务状态 #4273.

区分大小写的ClientID #4542.

缓慢的版本更新查询使其他 HTTP API 没有反应 #4499.

ARP 表刷新过程导致 PTR 请求过多#3157.

This is a small security-oriented update. This AdGuard Home version requires Go v1.17 and later to build, because older Go versions receive no further support, including security patches.

Aside from that, we've slightly updated $dnsrewrite modifier to support the user-defined Discovery of Designated Resolvers (DDR). We are planning on continuing to make more improvements to it in the future updates, see #4463.

The rest are minor changes and ever-present bugfixes.

Full Changelog

Security

User-Agent HTTP header removed from outgoing DNS-over-HTTPS requests.

Go version was updated to prevent the possibility of exploiting the CVE-2022-24675, CVE-2022-27536, and CVE-2022-28327 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.

This is a security release. There are no new changes besides the update of the Go programming language version.

More substantial changes are to come in the subsequent updates.

Full Changelog

Security

Go version was updated to prevent the possibility of exploiting the CVE-2022-24921 vulnerability. As the CVE page is still showing “reserved” at the time of publishing, see also golang/go#51112.

A small update to fix a couple bugs and shore up some Go vulnerabilities.

More substantial changes are to come in the subsequent updates.

Full Changelog

Security

Go version was updated to prevent the possibility of exploiting the CVE-2022-23806, CVE-2022-23772, and CVE-2022-23773 vulnerabilities.

Changed

Minor UI improvements.

Fixed

Optimistic cache now responds with expired items even if those can't be resolved again #4254.

Unnecessarily complex hosts-related logic leading to infinite recursion in some cases #4216.

This version contains bug fixes and cleanups 🧹. Also, there is a new minor feature: now you can rewrite responses for domains using the response code NOERROR. Similar rules will allow to get a successful response without records, e.g.:

|example.com^$dnsrewrite=NOERROR

Full Changelog

Added

Support for a $dnsrewrite modifier with an empty NOERROR response #4133.

Fixed

Wrong set of ports checked for duplicates during the initial setup #4095.

Incorrectly invalidated service domains #4120.

Poor testing of domain-specific upstream servers #4074.

Omitted aliases of hosts specified by another line within the OS's hosts file #4079.

You know, it is very hard to break your bad habits. We're still struggling with one, the overwhelming need to roll out hotfixes to AdGuard Home releases 😢

Now this one is a hotfix release for a really critical CPU overconsumption bug in v0.107.1.

Please update asap and with this, we wish you happy holidays!🎄

Full Changelog

Fixed

Infinite loops when TCP connections time out (#4042).

In a not-futile-at-all-we-swear 😅 attempt to fix all bugs before the New Year we're rolling out a hotfix to the recent v0.107.0. Hopefully, this time we got it all right. And if not, there are still a couple of sheets left on the calendar 📆 and the mug is still half-full with lukewarm coffee ☕

Acknowledgements

A special thanks to our open-source contributors: @Aikatsui and @mdawsonuk, as well as to everyone who filed and inspected issues, added translations, and helped us test this release!

Full Changelog

Changed

The validation error message for duplicated allow- and blocklists in DNS settings now shows the duplicated elements (#3975).

Fixed

ipset initialization bugs (#4027).

Legacy DNS rewrites from a wildcard pattern to a subdomain (#4016).

Service not being stopped before running the uninstall service action (#3868).

Broken reload service action on FreeBSD.

Legacy DNS rewrites responding from upstream when a request other than A or AAAA is received (#4008).

Panic on port availability check during installation (#3987).

Incorrect application of rules from the OS's hosts files (#3998).

We've had some big AdGuard Home updates in the past, but this one is to top them all. It's been brewing for almost eight months! 🙀 So no wonder there's heaps upon heaps of new features, improvements, bugfixes, and other changes. We'd better start listing them ASAP, or else we'll be risking missing the New Year's fireworks 🎆 🥂

Native Apple Silicon support

There's no shortage of killer features in this changelog, but this one takes the cake as the biggest of them all, without any doubt. You won't have to resort to Rosetta or any such solutions anymore if you want to configure AdGuard Home on a Mac with a Silicon chip.

RFC 9000 support In DNS-over-QUIC

It's not quite over nine thousand, but it'll do. The IETF has formalized QUIC this year with RFC 9000, and DNS-over-QUIC protocol finally supports it. If you haven't tried DoQ yet, consider this a sign.

`$dnsrewrite` rules and other DNS rewrites will now be applied even when protection is disabled (#1558)

Another popular demand. This change only makes sense, as DNS rewrites often carry a different purpose than simply blocking ads or trackers. You still can disable them by opening the admin panel, going to Settings → General settings, and removing the check mark from the Block domains using filters and hosts files box.

Note: rules contained in system hosts files (e.g. /etc/hosts) now have higher priority. This may result in more rewrites appearing in your Query log. If some of these rewrites are invalid, remove the corresponding lines from your hosts files or comment them out.

DNS-over-HTTPS queries now use the real IP address of the client instead of the address of the proxy (#2799)

Note that this change concerns only those proxies that you've added to the list of "Trusted proxies", otherwise it would be a major security risk. We wouldn't want anything of that sort to happen to you! 🙅‍♀️ Right now trusted_proxies can only be configured in AdGuardHome.yaml, but that might change in the future.

Optimistic DNS cache (#2145)

To reduce latency you may make AdGuard Home respond from the cache even when the stored entry is expired, while trying to refresh them at the same time🔄 This checkbox is located in Settings → DNS settings → DNS cache configuration and it's not ticked by default. Responses made from DNS cache are marked with a special label in the Query log.

Query log search now supports internationalized domains (#3012)

Internationalized domain names (IDNAs) are domain names that contain symbols in non-Latin script/alphabet, such as яндекс.рф or ουτοπία.δπθ.gr, for example. Previously, they were being converted to Unicode in AG Home Query log (xn--d1abqjx3f.xn--p1ai and xn--kxae4bafwg.xn--pxaix.gr in our examples), which is a detriment in most cases. Now IDNAs are displayed as is, and you can search for them without resorting to Unicode.

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:

# 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:

# 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.

The ability to set up custom upstreams to resolve PTR queries for local addresses and to disable the automatic resolving of clients' addresses #2704

This option will improve your DNS privacy when it comes to addressing local resources. Give it a go unless you want to share your private data with googles of the world.

Search by clients' names in the query log #1273

There's not much that can be said about this feature, it's quite self-explanatory: now you can search up queries by specific clients. 🤷‍♀️

However, we wanted to highlight it anyway since so many of you have asked for it for quite a while. Hopefully, we delivered! 😅

Have you ever thought about why traditions are so important?🧙‍♂️ Traditions help us remember that we are part of a history that defines our past, shapes who we are today, and who we are likely to become. This is why we at AdGuard respect our traditions, and the most important one is pushing the inevitable hotfix right after every major update.🔥🔧

Jokes aside, here's the list of things fixed and improved in this hotfix.

Changed

Increased HTTP API timeouts (#2671, #2682).

"Permission denied" errors when checking if the machine has a static IP no longer prevent the DHCP server from starting (#2667).

The server name sent by clients of TLS APIs is not only checked when strict_sni_check is enabled (#2664).

HTTP API request body size limit for the POST /control/access/set and POST /control/filtering/set_rules HTTP APIs is increased (#2666, #2675).

Fixed

Error when enabling the DHCP server when AdGuard Home couldn't determine if the machine has a static IP.

Optical issue on custom rules (#2641).

Occasional crashes during startup.

The field "range_start" in the GET /control/dhcp/status HTTP API response is now correctly named again (#2678).

DHCPv6 server's ra_slaac_only and ra_allow_slaac settings aren't reset to false on update any more (#2653).

The Vary header is now added along with Access-Control-Allow-Origin to prevent cache-related and other issues in browsers (#2658).

The request body size limit is now set for HTTPS requests as well.

Incorrect version tag in the Docker release (#2663).

DNSCrypt queries weren't marked as such in logs (#2662).

We took our sweet time with this update, but you'll most certainly find it to be worth the wait. The changelog contains three absolute 💥bangers and a laundry list of lesser changes.

🕵️‍♂️ Client ID support for DNS-over-HTTPS, DNS-over-QUIC, and DNS-over-TLS #1387

This feature would be really useful to those of you who run an encrypted DNS resolver on a public server. In short, you can now identify your devices not just by their IP address (which is, frankly, not too useful in a public server scenario 🤷‍♀️), but by using a special "Client ID".

Here's how it works:

First, you add a client and specify an arbitrary string as its "Identifier", for instance, my-iphone.

On the client device you can now configure:

DNS-over-HTTPS: https://example.org/dns-query/my-iphone

DNS-over-TLS: tls://my-iphone.example.org (requires a Wildcard certificate)

DNS-over-QUIC: quic://my-iphone.example.org (requires a Wildcard certificate)

Queries and stats are now properly attributed to your device.

🔐 AdGuard as a DNSCrypt-resolver #1361

DNSCrypt was the very first DNS encryption protocol that got some traction. It may not be as popular as DoH/DoT/DoQ now, but it is still viable. Moreover, performance-wise DNSCrypt is better than any of them. And now that v0.105.0 is out, AdGuard Home can be configured to work as a DNSCrypt resolver!

However, here goes the tricky part. We haven't yet exposed these settings to the Web admin panel so if you want to have DNSCrypt, you'll need to follow this instruction and do it via editing the configuration file (AdGuardHome.yaml). Not that it would scare you off, would it? 🤓

Regarding DNSCrypt clients - AdGuard for Android, Windows and iOS support it, Mac will get its support pretty soon. Besides that, here is a long list of client software that supports it as well.

🆎 `$dnsrewrite` and `$dnstype` modifiers #2102 #2337

AdGuard Home now supports two more powerful rule modifiers that will help blocklists' maintainers.

$dnstype lets you narrow down the rule scope and apply it only to queries of a specific type(s). For instance, Apple devices now support HTTPS DNS query type. While being generally a good thing, this new type may sometimes be harmful😲. By using $dnstype you can block it completely using a simple rule like this: $dnstype=HTTPS

$dnsrewrite is another powerful modifier that allows you to modify DNS responses. Note that this modifier is much more powerful compared to something like a hosts file.

Here are some examples:

||example.org^$dnsrewrite=SERVFAIL;; - return SERVFAIL for example.org and all it's subdomains

|test.example.org^$dnsrewrite=NOERROR;TXT;hello_world - add a TXT record for test.example.org

|example.org^$dnsrewrite=example.com - redirect example.org to example.com

|example.org^$dnsrewrite=1.1.1.1 - redirect example.org to example.com

You can find more examples in the documentation.

Added

Added more services to the "Blocked services" list #2224, #2401

ipset subdomain matching, just like dnsmasq does #2179

The host checking API and the query logs API can now return multiple matched rules #2102

Detecting of network interface configured to have static IP address via /etc/network/interfaces #2302

A 5 second wait period until a DHCP server's network interface gets an IP address #2304

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

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 the 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

Bugfixes... 😌 There's something about them that we just can't resist. We always want more! 🧟

When there's nothing more to fix, we just roll out a new major update, introduce some fresh bugs and start all over. It's a circle of life ☯️

Luckily, there are still some to prey upon in v0.104. Have a look at what we've fixed this time:

Fixed

Don't expose the profiler HTTP API #2336

Load query logs from files after loading the ones buffered in memory #2325

Don't show Unnecessary errors in logs when switching between query log files #2324

Don't show 404 Not Found errors on the DHCP settings page on Windows. Show that DHCP is not currently available on that OS instead #2295

Fix an infinite loop in the /dhcp/find_active_dhcp HTTP API method #2301

Various internal improvements

Those who pay close attention to AdGuard Home releases know that we keep hotfixes close to our hearts 🔥♥️ This time we held for as long as we could, but ultimately gave in to the urge 😔

Here's a patch to v0.104 with some fixes and minor improvements.

Fixed

Solve the permission denied error when launching a DHCP server on Linux using Snap #2228. Users experiencing this issue should refresh their snap and call:

snap connect adguard-home:network-control

This won't be required in the future versions.

Use matching fonts in the Custom Filters textarea #2254

Show the correct query type for DNS-over-QUIC queries in query log #2241

Increase the default number of simultaneous requests to improve performance #2257

Always set a secondary DNS in DHCP #1708

Improve stability on DNS proxy restart #2242

Improve logging on DNS proxy restart #2252

Don't show a “Loading” message and don't rerequest logs once we've reached the end of logs on the query log page #2229

Various internal improvements.

We have something special for y'all today. Not just an implementation of a new feature but the first ever implementation of a new feature! 😮 This is about DNS-over-QUIC, a new DNS encryption protocol — read on to learn more.

Ah, yes, there's also a bunch of other good stuff, too: DHCP-related changes, a .mobileconfig generator for iOS and macOS, and a handful of other enhancements and bugfixes.

DNS-over-QUIC support #2049

AdGuard Home now natively supports a new DNS encryption protocol called DNS-over-QUIC. DoQ standard is currently in the draft state, and AdGuard Home (and dnsproxy) is it's first open-source implementation.🥇

So what's good about it? 🤔 Unlike DoH and DoT, it uses QUIC as a transport protocol and finally brings DNS back to its roots — working over UDP. It brings all the good things that QUIC has to offer — out-of-the-box encryption, reduced connection times, better performance when data packets are lost. Also, QUIC is supposed to be a transport-level protocol and there are no risks of metadata leaks that could happen with DoH. 🔒

At this moment, the only major public DNS resolver that provides DNS-over-QUIC is AdGuard DNS. 😎 Use quic://dns-unfiltered.adguard.com in the upstreams settings to start using AdGuard DNS "Non-Filtering".

DHCP rework: DHCP6 support, custom DHCP options

We did a huge rework of our DHCP server implementation. Thanks to it, AdGuard Home now supports DHCP6 and allows setting custom DHCP options.

Please note that in order to set DHCP options, you'll need to edit the configuration file.

Add support for DHCPv6: #779

DHCPv6 RA+SLAAC: #2076

DHCP: automatic hostnames: #1956

Add DHCP Options: #1585

iOS and MacOS .mobileconfig generator: #2110

iOS 14 and macOS Big Sur natively support DNS-over-HTTPS and DNS-over-TLS. However, it's not that simple to configure them — you need to install a special "configuration profile" for that. 🤯 In order to make things easier, AdGuard Home can generate these configuration profiles for you. Just head to "Setup Guide" -> "DNS Privacy" and scroll to iOS.

Binary transparency

AdGuard Home binaries are now signed with our GPG key and you can now easily verify that they really come from us: https://github.com/AdguardTeam/AdGuardHome/wiki/Verify-Releases
