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 new AdGuard for Mac beta is a long-awaited one, and we tried to deliver. Basically, all the aspects of the program has been improved: many adblocking-related issues to improve the filtering quality, enhanced network security and reworked User filter. More details below.
Ad blocking
[Added] $network basic rules modifier #171
[Changed] The ~third-party modifier behavior #177
[Fixed] Content filtering exception rules #176
[Fixed] Error while parsing a wide filtering rule #175
[Fixed] Replace rules aren't applied to .m3u8 files content #178
[Fixed] Regular expressions with $ aren't processed properly #167
[Fixed[ The script is being removed/cut if there is an $empty modifier in the rule #209
[Fixed] Cosmetic filters are being applied to pages whitelisted by a $document exception #189
[Improved] The range of $$ rules has been increased #196
[Improved] "ExtendedCss" module has been upgraded to v1.0.8 #216
[Improved] The trimming limit for request URLs has been increased #214
[Improved] The $network modifier has been extended, it can now be an exception as well #190
Networking
[Added] An option to exclude websites with EV certificates from filtering #170
An option already familiar to Windows users. Some websites feature Extended Validation (EV) SSL certificates, which require a very strict verification process and offer a stronger guarantee that the website is plausible and trusted. Usually, they are bank websites, payment systems etc., and they normally do not have many ads anyway, if any.
We have also improved the security aspect of Adguard by addressing some security-related issues (#186, #194).
[Fixed] SHA-1 intermediate issue #194
[Fixed] Adguard cannot handle huge chunks properly #218
[Fixed] Connection is allowed when DH1024 is in use #186
[Fixed] "strict-dynamic" CSP is not handled properly #203
[Fixed] There is an empty response from local.adguard.com in some cases when HTTPS is used #206
UI
[Improved] Filter editor has been reworked #56
Now it has become possible to enter the 'advanced editing mode'. Basically, it means that the User filter turns into a single text area which you can work with as in any text editor: copy/paste several lines at once and apply all changes at once and not line by line. The search tool will help you to find or replace anything you need. All in all, it should be a welcome change for all the aspiring filter developers.
[Fixed] The 'expiring trial' warning translation #169
[Fixed] The number of remaining subscription days is not displayed in Adguard toolbar #191
Other
[Improved] Adguard can now be launched from an external drive #210
A niche but useful improvement. In case you prefer to store your data on an external drive and switch between different desktops a lot. No need to update your user filter and other settings separately on every Mac separately anymore, just have AdGuard installed on an external drive.
[Changed] The SSL exceptions list has been updated
[Fixed] Yandex mail compatibility issue #160
