AdGuard v4.5.3 for iOS: improved filtering and DNS protection

This update is pretty important since it improves the DNS protection feature, thanks to updated DnsLibs (our DNS filtering engine). We also updated two other libraries that are essential for the app’s performance: TSUrlFilter and Scriptlets.

Please note that starting with this version, AdGuard for iOS supports only iOS 13 or later.

DNS protection: fixed DNS leaks and connection instability

Updating DnsLibs to v2.5.17 brought some significant improvements to our DNS protection feature — a feature that makes it possible to block ads system-wide. Among other things, we implemented a fix that prevents DNS leaks and connection instability when changing networks. In other words, you will no longer encounter these problems when switching, for example, from your home Wi-Fi to mobile network on your iPhone.

Updated Scriptlets and TSUrlFilter

We updated two essential libraries: Scriptlets (JavaScript enhancement for filtering rules) to v1.10.25 and TSUrlFilter (advanced protection filtering engine) to v2.2.18. AdGuard for iOS now provides the most up-to-date filtering quality, which means ad blocking on YouTube and other websites is even more efficient.
