+## General Change Management
+Smart Contract code in Qubic is generally immutable. This ensures stable quality and security accross the network.
+However there are situation where you want to change your SC.
+
+### Bugfix
+A bugfix is possible at any time. It can be applied during the epoch (if no state is changed) or must be coordinated with an epoch update.
+
+### New Features
+If you want to add new features, this needs to be approved by the computors again. Please refer to the [Deployment](#deployment) for the needed steps. The IPO is not anymore needed for an update of your SC.
