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.
The Christmas came early this year for Adguard for Mac users - a new version comes out today :) It significantly improves ad blocking, namely introducing Extended CSS support and several new modifiers. Networking and UI have unergone some fixing and tweaking too, so Adguard will become more stable and easy in use.
Ad blocking
[Added] Extended CSS support #109, #120
This is a very important addition in terms of future (and present) possibilities that it opens for ad blocking. Extended CSS is a module for applying CSS styles with extended selection properties. Basically, it means that we will be able to select and, therefore, block some elements that we would not be able to block otherwise. Notably, this concerns such things as 'Sponsored posts' on Facebook.
