Disclaimer Adguard for Windows is not an open source project. We use github as an open bug tracker for users to see what developers are working on.
In this release candidate we offer only one change, but quite important change it is.
[Added] :matches-css-* pseudo-class support AdguardTeam/ExtendedCss#7
This pseudo-class allows to select any element by its style. Why do we need it? Some websites use a very complicated layout to circumvent ad blocking (one of the best examples is mail.yandex.ru). Ad layout is completely similar to the valid elements aside of the Ad label which is added with a ::before pseudo-element. With this new pseudo-class such ad element can be selected and, therefore, blocked. Custom filtering rules enthusiasts can learn more from the comments in the task itself.
