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.
We are getting closer and closer to Adguard for Mac release. This means we don't want any, even insignificant bugs and errors left. This is why we are willing to release beta versions with a changelog this small. To be more precise, this is a release candidate - if everything is fine with it, it will become a new release.
