+# Iteration 4 release notes
+
+The user experience of the mobile application has been gone through big changes. The main focus of this iteration was improving the usability and speed (from the point of an user) of the application that was built during the last 3 iterations.
+* It is no longer necessary to click on any buttons in order to read information such as name, expiration date etc from the ID card. If the user has saved CAN and the application is running on the foreground, it is only necessary to put the ID card against the smartphone.
+* The CAN is now saved automatically when the user has entered a 6 digit input to the CAN field.
+* The PIN 1 notification dialogue has been replaced with a switch toggle that enables saving the PIN 1. The toggle state is persistent so it is not necessary to turn it off each time the application has been launched.
+* The features that have been implemented so far should be now bug free.
+
+In addition the documentation has been updated to reflect the current state of the development.
