+# Upgrading Icinga PowerShell Framework
+
+Upgrading Icinga PowerShell Framework is usually quite straightforward. 
+
+Specific version upgrades are described below. Please note that version updates are incremental.
+
+## Upgrading to v1.1.0 (pending)
+
+### Behavior changes
+
+The behaviour on how the `-AcceptConnections` argument of the setup wizard is working has been fixed. Prior to version v1.1.0 the opposite effect took place.
+
+Previous behaviour:
+
+Setting `-AcceptConnections 1` would continue with having to configure endpoint configurations while `-AcceptConnections 0` would open the Windows Firewall for incoming connections
+
+New behavior:
+
+Setting `-AcceptConnections 1` will only configure the Agent to wait for parent node(s) and open the Windows firewall for incoming traffic.
+Using `-AcceptConnections 0` is now working properly by letting the Agent establish the connection to the parent node(s)
