+### Reverts
+
+* AccessFlag extensions not working with IDE ([0bfb92a](https://github.com/revanced/revanced-patcher/commit/0bfb92a0cbd72df5ba513264efb583e201cfcf82))
+* previous commits check for dupes in dexFile, not cache ([e810197](https://github.com/revanced/revanced-patcher/commit/e810197e2aa64534f2e8637165d884cbefbce8ae))
+
+
+### BREAKING CHANGES
+
+* arrayOf has to be changed to listOf.
+* Method signature of Patcher#save() was changed to comply with the changes of multidexlib2.
+* Removed usage of ASM library
+* 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.
