Disclaimer Adguard for Mac is not an open source project. We use GitHub as an open bug tracker for users to see what developers are working on.
CoreLibs is the centerpiece of the upcoming AdGuard 2.0 for Mac update, and we've just discovered some minor problems with it. Nonetheless, we consider them important enough to release one more beta to fix these problems before unleashing the new stable version into the world. We've also made a few localization updates.
