While we are still polishing CoreLibs and are not ready to implement it just yet, we can sweeten the waiting with this new release. New “Nightly” update channel, added TLS1.3 support, improved performance and many more other changes.

[Added] Nightly update channel

The concept of a “Nightly” build is very simple. It literally means “a build that is released at the end of every day”, hence “nightly”. In reality, it may not happen every single day, but rather every 3 or 4 days, but the idea is there. All the latest changes made by developers will be included in the nightly build (yes, including possible bugs — be prepared!). If you feel that beta is not enough for you, and you need to be a step ahead of the rest, this is the choice for you. Just go to AdGuard settings and switch to Nightly update channel.

[Added] TLS1.3 Support (draft 28) #2155

TLS 1.3 is a new version of the cryptographic protocol used to encrypt messages sent via HTTP. It is faster, more secure and overall better than its predecessors. It has not been accepted by IETF as a standard yet, but it is only a matter of time. The process has already started, and we want to be at the forefront, and thus we have already added the TLS 1.3 (draft 28) support. As not everyone supports TLS1.3 yet, there can be problems on some websites potentially, so we added a new advanced setting to switch between TLS versions at will.

[Added] Option to subscribe to a filter by clicking a special link on a webpage #1945

Many filter developers put a special subscription link on their filters’ homepage. Now AdGuard is able to detect these links when you click on them and will ask you if you’d like to subscribe to that filter right away. A minor thing, but it will save you just enough of extra clicks to be worthy.

[Added] A notice to inform about closed connections to websites with EV certificate #2015

Some websites have so-called EV (extended validation) certificates — basically, this means that the owner went through a very long and thorough process of validating their identity. In other words, these websites are generally the safest on the web. Filtering these websites is often extensive, as they rarely have ads anyway, but can sometimes lead to conflicts. AdGuard provides an option to disable filtering for such websites, and if it is enabled, a notification will inform you when you visit them for the first time. Clicking on the notification will allow to force filtering on the website anyway.

[Added] Stealth mode options applied to requests added to Filtering log #247

This is something a lot of aspiring filtering rules creators asked for. Knowing which Stealth Mode options affected this or that request is often crucial when working on a new rule. Now you can find it right in the Filtering log when you select a request. For sure, this sounds a little bit nerdy for an average user, but we try to take into account needs of all our users, casual and advanced alike.

[Changed] Default builder has been drastically reworked #1965

Basically, this is the change that caused the build size reduction that was advertised in the introduction. As the app accretes new features over the years and the code mounts up, this becomes more and more relevant. Thanks to this change, now we can add even more!

[Improved] Better support for visually impaired users #2068

AdGuard tries to provide the best online experience for all users alike, and visually impaired users are no exception. Starting with this version, AdGuard menus are much better suited to be read by NVDA Screen Reader and other screen reading programs.

[Improved] Filters update procedure’s performance #2211

If you had the misfortune of a habit to update your filters often, you certainly noticed that it took quite a lot of time, as well as installing new filters. We addressed this problem, the situation should change drastically for the better now.
