+### Breaking changes
+
+- The method `addIntegrationToSdkVersion(Ljava/lang/Class;)V` has been removed from the core (`io.sentry:sentry`) package. Please make sure all of the packages (e.g. `io.sentry:sentry-android-core`, `io.sentry:sentry-android-fragment`, `io.sentry:sentry-okhttp`  and others) are all aligned and using the same version to prevent the `NoSuchMethodError` exception.
