This is the first alpha version of Adguard for Android v2.5.

It brings only one new feature, but this feature is really huge: HTTPS filtering! Check out the app settings to learn more about it.

Attention: this is an early build, not yet ready even for beta testing!

Ad blocking

[Added] Added popular filter subscriptions: https://github.com/AdguardTeam/AdguardForAndroid/issues/210

List of added filter subscriptions:

• ABPindo
• EasyList China
• EasyList Czech and Slovak
• EasyList Hebrew
• EasyList Italy
• Liste AR
• Liste FR
• ABP Japanese Filters
• Adblock polskie reguły

[Added] $generichide modifier support: https://github.com/AdguardTeam/AdguardForAndroid/issues/64
[Added] $genericblock modifier support: https://github.com/AdguardTeam/AdguardForAndroid/issues/63
[Changed] Improved $popup rules: https://github.com/AdguardTeam/AdguardForAndroid/issues/207
[Fixed] A bug with HTML filtering rules - void elements never removed: https://github.com/AdguardTeam/AdguardForAndroid/issues/214
[Fixed] An issue with "base url": https://github.com/AdguardTeam/AdguardForAndroid/issues/212
[Fixed] Rules with $elemhide modifier now applied to "Documents" only: https://github.com/AdguardTeam/AdguardForAndroid/issues/181

UI changes

[Added] New "Notification Icon" setting option: "Notification without icon": https://github.com/AdguardTeam/AdguardForAndroid/issues/222

So now we now have 4 options:

1. Default icon. Icon and notification are always visible.
2. Colored icon (only in Android 4.X). Icon and notification are always visible.
3. Notification without icon. Icon is not visible. Permanent notification is visible, but it has low priority, so it is semi-transparent and placed below all other notifications.
   4 None. No icon, no notification.

[Changed] Make "Protection paused" a permanent notification: https://github.com/AdguardTeam/AdguardForAndroid/issues/231
This change should help with #223. When Adguard pauses protection, sometimes Android may kill it's process and then do not bring it back.

[Fixed] "Filter DNS requests" feature does not work with mobile connection: https://github.com/AdguardTeam/AdguardForAndroid/issues/191

We have improved "Filter DNS requests" feature, now it is much more reliable and works for both Wi-Fi and Mobile connection. This feature may drastically improve the battery usage, so I recommend that beta testers to try it.

Multiple TCP stack improvements

Problems with large files download (#92, #98)

Previously there were problems with downloading large files, especially from Google Play. It is not the case anymore, you don't have to disable Adguard just to update your favorite app or download a new game.

Overall performance improvement

With recent changes Adguard has become faster, more stable and less resourse consuming. It was possible due to optimization of several 'bottleneck' situations.

Other changes:

This is a release candidate for "2.1 patch" milestone.

• Multiple improvements in our TCP stack implementation #45, #92, #98, #101, #106, #109, #110, #112
• Moved firewall icons-cache to Cache folder to be able to clear it from app settings #89
• Fixed unnecessary restart of protection in Proxy mode #90
• Proxy mode: DNS cache is now flushed on network reconnect #91
• Multiple GUI improvement in Low-Level Settings #94, #96, #97, #103
• Optimized Pcap functionality in Low-Level Settings #97, #105
• Update channel options are hidden for Amazon builds #102
• Fixed handling of HTTP CONNECT requests without Host header #113
• Small fix in UI of Send Feedback activity #118

Firewall changes

Firewall settings section (#61)

Now it's up to you whether you need the Firewall feature or not. So, yeah, this feature can now be enabled and disabled. Very useful if you were setting different preferences for different apps and now would like to temporarily disable Firewall and won't lose all the settings herewith.

Firewall: Added an ability to temporarily pause blocking for foreground application (#27)

This feature allows to return the Internet access with one tap. Let's say you have prohibited some app (like Maps or any other using geolocation) to go online without you knowing. But when you need the app to connect to the Internet immediately - you no longer have to open Adguard, go in Firewall and change the settings. Now you can regain access to the network right in the app.

Low-level settings #42

Most of users don't really need them. Such settings were made to make the troubleshooting faster, to solve some very rare problems or for a really specific configuration of the program. Now we won't spend time on the assembling of a special version for your device and you - on its download and installation. We will be able to tell right away what to change to solve the problem. So the support is now easier, and these settings are needed to parse some tricky bugs.

Let's go down the list:

pref.vpn.ipv4.force.default - disables the routes we use to exclude LAN from filtering.

pref.vpn.ipv4.force.complex - settings reverse to the previous one. Regardless of the network configuration use of routes excluding LAN. Usually, we do not exclude the LAN networks with a complex configuration. This setting will bypass the restriction.

pref.vpn.ipv6.bypass - forcibly exclude filtering of IPv6 networks. In this case, IPv6 will work, but will not be filtered.

pref.vpn.ipv6.disable- forcibly disable filtering for IPv6 networks. In case,IPv6 will not work at all.

pref.vpn.tun.mtu- the maximum size of the data package, which is used in VPN. In general, the rule is - the larger the package, the less CPU time spent on creating packages from the program, and the faster everything works. On the other hand, when the size is too large, VPN may cease to work at all, or fail to start. The recommended interval for the experiments is from 1500 to 9000.

pref.vpn.disable.pause - (#84) disable Adguard automatic restart functional when disconnecting/connecting to the network. Why needed? When the VPN is enabled, routes are built in accordance with the current network configuration on the device. Sometimes it happens that when you connect to another network, these routes no longer correspond to the new configuration, and VPN ceases to operate. Automatic restart is needed to avoid this situation.

Reworked DNS filtering

To 'catch' the requests to DNS servers (which resolve domains in IP) we had to set the preferences for our VPN, which provide access to some server outside the current network. We used one Google' and one Yandex' servers. But it turned out that there are providers and tariffs which block access to the external servers. Now, we look at what DNS server the user has. Then set some fake DNS in VPN settings. And when the query is executed to this fake server, we change the address with the one that the user has.
