It has been a very long time since the last AdGuard for Mac release. We definitely don't want such hiatus to become a routine – expect the next one much sooner.

And in this one we've made some positive changes to the UI and improved the filtering quality by a lot. Read the full changelog below.

Ad blocking

[Fixed] AdGuard doesn't filter apps from the WebCatalog app #165

Previously, AdGuard wasn’t able to filter apps installed with WebCatalog, and they couldn’t even be added to the list of filtered apps manually. This issue gets fixed in this version.
• [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] Content rules are applied even when there is a $document exception #234
• [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] Wrong cyphers order #224
• [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] AdGuard Crashes when receives new metadata from backend #220
• [Fixed] There is an empty response from local.adguard.com in some cases when HTTPS is used #206
• [Fixed] Several network errors and compatibility issues

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.

• [Added] Add "Reset settings..." option #180
• [Changed] "System Extension Blocked" issue on macOS 10.13 (High Sierra) #217
• [Changed] Filters' names have been adjusted #187
• [Changed] AdGuard to AdGuard #231
• [Fixed] Wrong date of establishment in "About AdGuard" section #205
• [Fixed] Several localization fixes and updates
• [Fixed] The 'expiring trial' warning translation #169
• [Fixed] The number of remaining subscription days is not displayed in AdGuard toolbar #191
• [Fixed] UF is always turned on after restarting the app #237
• [Fixed] Interface bug with filters list #236
• [Fixed] Misplaced title in Support window #235

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

IMPORTANT UPDATE: compatibility with Chrome 59 and newer. The changes are few, but crucial.

[Fixed] local.adguard.com certificate is considered invalid by Chrome v59 #183

It may not seem like much, but without this change, Adguard would be partially incompatible with the newest Chrome versions. Needless to say, Chrome is one of the most popular browsers among Mac users, so it is hard to overstate the importance of this fix.

• [Changed] Bundle ID for Waterfox app #164

A small hotfix containing a couple of changes.

• [Fixed] Adguard maintains network connections even if the computer is in idle mode #163
• [Improved] Cosmetic exception rules compilation speed #173

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 undergone 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.


• [Added] $important modifier #132
  This new addition is an significant one, but mostly relevant for creators of custom filter rules. With it's help you can give certain rules higher priority.


• [Added] $websocket modifier #131
• [Changed] Updated default HTTPS exclusions list #124
• [Fixed] $empty modifier behaviour #108, #143
• [Fixed] Latin extended symbol in a filter rule interferes with filtering #134
• [Fixed] $replace rule can't be applied along with the other rules #133

Networking

• [Changed] HTTPS is now used for safebrowsing requests #148
• [Changed] WoSign and StartCom certificates are now distrusted #141
• [Changed] New separate server is used now for filter updates #139
• [Fixed] $replace rules break content charset #147

UI

• [Changed] CMD+Backspace key combination can now be used to delete filters from the filter list #9
• [Changed] "Check filter updates" action moved to settings menu #116
• [Fixed] Incorrect filter is displayed in "Filtering Log" #129
• [Fixed] $replace rules are displayed correctly in the filtering log #150
• [Improved] Allowed pasting mulitple rules at once in filter area #126

Hello! Last Adguard for Mac version was released in February, so we felt a bit guilty and decided to release a new one :) There is quite a bit of various fixes and changes here, as you can see in the changelog below, but the most important, or rather the most impactful ones, are those that affect performance - specifically, we mean #88 and #91 (you can find more detailed description for these changes below). Overall, Adguard will become faster now, and thanks to the better performance, Adguard will now consume significantly less battery resourse. But not only that, for example, we drastically improved browsing of some of the most problematic websites when IPv6 is enabled (#93).

Ad blocking

[Improved] Basic filtering rules processing speed was optimized #91

Optimizing basic filtering rules processing is very important since basic rules are the most resourse-consuming among all. This change will result in Adguard working faster and spending less resourses.

• [Changed] $replace rules now have higher priority than other basic rules #49
• [Changed] Origin is used as Referer for requests Referer isn't defined for #84
• [Fixed] Adguard crash because of huge data: URLs #81
• [Fixed] Adguard does not ignore "base" tag "href " attribute while constructing absolute URL any more #80

• [Fixed] twitch.tv filtering issue #105
• [Improved] Increase content filtering rules maximum length limit #101

Networking

[Changed] Connections are not kept alive for too long now if 'HTTP keep alive' timeout is specified #88

Previously the 'keep-alive' time for connections was higher, and Adguard consumed more battery resourse than it should. Now, when we lowered the connections 'keep-alive' time, the resourse consumption during the 'idle time' will be significantly lower as well.

• [Changed] Webdav methods are supported now (specifically REPORT) #85
• [Changed] Rewritten mechanism of checking the websites availability #93
• [Fixed] After blocking a POST request, next request is read only when data was read to end #68
• [Fixed] Adguard prevents UDP traffic on 443 port #90
• [Fixed] Adguard fails to detect HTML on some websites #100

UI changes
