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!🎄
Infinite loops when TCP connections time out (#4042).
Versiune 0.107.1 de la data 12 ianuarie 2022
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 ☕
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!
The validation error message for duplicated allow- and blocklists in DNS settings now shows the duplicated elements (#3975).

Versiune 0.107.0 de la data 12 ianuarie 2022
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_proxiescan 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
ουτοπία.δπθ.gr, for example. Previously, they were being converted to Unicode in AG Home Query log (
xn--kxae4bafwg.xn--pxaix.grin 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.
A special thanks to our open-source contributors: @Aikatsui, @anbraten, @bruvv, @DandelionSprout, @fvdm, @hnefatl, @markhicken, @p27877, and @systemcrash, as well as to everyone who filed and inspected issues, added translations, and helped us test this release! 🙏

Nothing serious though, we didn't even break anything. Just cleaning up some minor bugs. 🧹
Versiune 0.106.0 de la data 19 mai 2021
Quite a lot of changes this time around, even if there aren't as many standouts as in some of the previous updates. We're sure that you'll be able to find a line or two in the changelog that speaks to you!
And one of the reasons for that is the constant support from the community. 👥👥 Special thanks to our open-source contributors: @jvoisin and @Paraphraser, as well as to everyone who filed issues, added translations, and helped us to test this release! 🙇
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.
"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_checkis enabled (#2664).
Error when enabling the DHCP server when AdGuard Home couldn't determine if the machine has a static IP.

DNSCrypt queries weren't marked as such in logs (#2662).
Versiune 0.105.0 de la data 12 februarie 2021
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,
On the client device you can now configure:
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.
AdGuard Home now supports two more powerful rule modifiers that will help blocklists' maintainers.
$dnstypelets you narrow down the rule scope and apply it only to queries of a specific type(s). For instance, Apple devices now support
HTTPSDNS query type. While being generally a good thing, this new type may sometimes be harmful😲. By using
$dnstypeyou can block it completely using a simple rule like this:
$dnsrewriteis another powerful modifier that allows you to modify DNS responses. Note that this modifier is much more powerful compared to something like a hosts file.
Here are some examples:
example.organd all it's subdomains
|test.example.org^$dnsrewrite=NOERROR;TXT;hello_world- add a

Versiune 0.104.0 de la data 12 februarie 2021
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.comin 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.
