Everyone who were using signatures in AMODIT knows that making any change to signed item leads to expiring signature. Therefore if you sign a form it becomes read-only and you need to cancel signature manually to make changes in the form. However, there are many situations when you can make changes and make signature expire. The problem with such a situations was that it was not always obvious why signature expired. This is why we have extended history of a case and since now it shows cause of expiration. It can save a little time when trying to understand what actually happened.
