+* Rename `net.revanced` to `app.revanced` ([3ab42a9](https://github.com/ReVancedTeam/revanced-patcher/commit/3ab42a932c8d5027d554106dfe8e1299ebc1ac7f))
+
+
+### Features
+

+
+
+### BREAKING CHANGES
+
+* Array<Int> was changed to IntArray. This breaks existing patches.
+* Package name was changed from "net.revanced" to "app.revanced"
+* Method signature of execute() was changed to include the cache, this will break existing implementations of the Patch class.
+* Patch class is now an abstract class. You must implement it. You can use anonymous implements, like done in the tests.
