Adguard Release Notes

June 1, 2021

AdGuard Browser Extension v3.6.5 is released.

We’ve added support for the $removeparam modifier which allowed us to get rid of the old Remove tracking parameters setting and add a new one that enables AdGuard URL Tracking filter. This will make deleting tracking parameters more flexible, so that everybody can create $removeparam user rules for their needs.

Moreover, in addition to “Do-Not-Track”, another signal appeared in the Stealth Mode settings — “Global Privacy Control”. These signals are sent to the websites you are visiting not to track you and to hide your search queries. Finally, we’ve added the birthday promo to the extension — AdGuard turns 12 on June 1!

Changelog

[Added] Global Privacy Control signal in Stealth Mode

After the recent v7.6 release a small percentage of users encountered a rather severe issue of not being able to update any filters, or even the app itself. This problem isn't very common but extremely critical to those who ran into it, so it justifies an immediate hotfix.

If you're one of the unlucky ones to have this problem, AdGuard will not update automatically for you. You need to check for updates manually or reinstall the app.

[Fixed] AdGuard cannot connect to the Internet to check filters updates / license status #3758

The explanation for this problem is quite technical. No reason to cite it here, you can find the detailed explanation in this comment by AdGuard's CTO.

Changelog

[Fixed] No filtering until "Filter localhost" is enabled after updating from v7.5 to v7.6 #3762

[Other] Minor fixes & improvements

April 21, 2021

Usually, it takes us north of 2-3 beta versions to prepare the next AdGuard for Windows release. But not this time: the first (and only) beta for v7.6 carried enough impact on its own. We added custom DNS filters, DNS-over-QUIC support for AdGuard DNS, and, of course, made the app compatible with AdGuard VPN.

[Enhancement] Custom DNS subscriptions support #3641

In v7.5 we introduced DNS protection module. To refresh your memory: it offered the option to select any DNS server instead of the system default as another way to enhance your online privacy. What it didn't offer is any way to customize the DNS filtering. Once you selected the server and the preferred encryption protocol, you were set.

In this release, we give you a range of new options to shape the DNS filtering the way you want. It includes several tools, all of which can be found inside the DNS filters editor section.

DNS user rules — the most basic way to block/allow DNS requests. Works very similarly to the regular User rules. Note that it supports DNS filtering syntax, which is much less complex than the syntax for network filtering. …

This is a rather uncharacteristic update for AdGuard for Mac. There's no real headliner, but instead a bunch of bugfixes, low-scale improvements, and localization updates. Important! Starting with this update, AdGuard will only work on macOS 10.12+. Unfortunately, the older macOS versions do not have capabilities to support the advanced techniques we use in our filtering engine.

Changelog

[Enhancement] Update CoreLibs to 1.7.189 #835

[Fixed] Some text strings on the initial setup screen are clipped #785

[Fixed] Opera browser isn't filtered in Network extension mode #800

[Fixed] Switching between system profiles causes AdGuard to crash #805

[Fixed] hepsiburada.com - HTTPS filtering issue #1406

[Fixed] blockchain.com is broken #1411

[Other] Added Dutch localization

[Other] Microsoft Outlook removed from the list of applications filtered by default

[Other] Added AdGuard Browser Assistant extension support in Edge browser

February 18, 2021

Long time ago scientists discovered an interesting phenomenon. While we typically think that what we most want is to actually get what we want, the most intense source of pleasure is in looking forward to getting what we want. That's the dopamine system, also known as the wanting system.

It's been months since Apple added native DNS encryption support to iOS and you might've thought that we at AdGuard just have been lazy not adding support too? Not at all! We've just been trying to follow science and provide you with as much pleasure as possible. Finally, the intensification period ends and catharsis begins!

Native support for encrypted DNS #1589

So in 2020 Apple platforms started natively supporting encrypted DNS. Namely, two protocols were supported — DNS-over-TLS and DNS-over-HTTPS (DoT and DoH). Earlier you could set up and manage DNS profiles in AdGuard. Yet, the solution wasn’t so snorky. Now we've made things simple: there is no need to download and install DNS profiles, just enable Native implementation in AdGuard for iOS settings:

This release is mainly focused on bug fixes and minor improvements. Yet, it has a feature that one can’t ignore — DNS-over-QUIC support! ​ [Other] DNS-over-QUIC support (AdGuard DNS)

The first thing you should know about DNS-over-QUIC (DoQ) is that it's a new encryption protocol. Not as new as a concept, but very new in terms of practical application. In fact, AdGuard introduced the very first public DNS servers that support DoQ! The feature is still experimental — AdGuard for iOS is one of the first open-source implementations of DNS-over-QUIC — but it's perfectly functioning and we encourage you to try it.

The most common DNS encryption protocols are DNS-over-HTTPS and DNS-over-TLS (DoH and DoT correspondingly). What makes DoQ special? A bunch of things: out-of-the-box encryption, reduced connection times, and better performance in cases of lost data packets. ​

Today we are launching a small but still very important hotfix. Namely, the compatibility with the new Chrome 87 was improved and the CoreLibs was updated.

[Other] ERR_HTTP2_PROTOCOL_ERROR on some websites #1374

This week Chrome 87 was released, which has a compatibility problem with AdGuard when using the HTTP/2 filtering protocol - some sites may experience regular hangs and download errors. In this update we have improved HTTP/2 filtering compatibility with Chrome 87, it is recommended to upgrade to the new stable version as soon as possible. :)

[Fixed] BigSur: AdGuard can't start protection in Network Extension filtering mode because of codeSignatureInvalid error

Also in this update, the issue which many Big Sur users encountered was fixed. AdGuard network extension couldn't pass the authenticity verification of the developer's signature. Because of that, it was impossible to turn the Network Extension mode on and to enable AdGuard protection.

Changelog

[Fixed] AdGuard stops working after the system is out of sleep #781

[Fixed] Change the KEXT behavior in case of a change of user #769

[Other] Protection switch is stuck after system update

The biggest thing about AdGuard v2.5 for Mac is better compatibility with Big Sur. Thanks to adoption of System Extensions, AdGuard will work better on the newest macOS iteration — read below to find out the details. Other than that, we made a lot of changes and enhancements to CoreLibs, which will result in an overall better filtering quality.

[Enhancement] System Extensions support in Big Sur #692

First of all, what are System Extensions? It all started in 2019 when Apple decided to minimize the amount of code that's executed in kernel. The old framework — Kernel Extensions — was declared as deprecated. As an alternative, Apple offered System Extensions, and specifically Network Extensions as a framework for apps that filter traffic.

In macOS 11 (Big Sur), the old Kernel Extensions will not be supported (partly or at all), so we are adding support for the new framework. If you're already on Big Sur preview, make sure your AdGuard works in Network Extensions mode: open AdGuard's menu -> Select Preferences... -> Network -> Select Mode.... "Kernel Extension" mode should be grayed out, and "Network Extension" mode should be selected.
