+# Migrating to Version 2
+
+RxMagneto 2 brings some breaking changes from version 1. The entire library is re-written using RxJava 2. All the Observables are now changed into Singles, so there will be some re-work for you. You also do NOT need to perform these operations in the background thread as it is automatically done for you.
+
+The core functionality of the library remains the same. Every feature in the new version of this library works in the same way and returns the same result as the previous version.
