Update subsriptions.xml with every release build
In https://issues.adblockplus.org/ticket/6017 we implemented the latest version of subscriptions.xml and made some adjustments to the parser to handle the new format. Now we use the same xml file as in ABP core.
In a second step we need to implement a gradle task that updates subscriptions.xml with every release build. We can do it the same way like we update the two bundles filter lists.
