Security enhancements have been implemented in this release to address known security issues from previous versions and to reduce the possibility of malicious attack. These security enhancements include, improved inter-operability through the introduction of new INI parameters, trusted network authentication, and the addition of assigning roles to CitectSCADA runtime users, as you currently do for Windows users.
Note: The [Privilege]Shutdown parameter is now used to specify the necessary privilege level of a user to perform a shutdown operation triggered by clicking the Close button of the project (default privilege level is 8).
