I have been trying to use this function system.security.logout() to logout from my Perspective script as described in the help.

After attempting to debug my script I found that is not available.

Please update the documentation to reflect this and possible make note in the earlier versions that is no longer available.

Not a bug. As documented for the entire `system.security` namespace, these are Vision-only.

They are only for vision projects, not perspective. The documentation notes this correctly as it is vision scoped. You can access it in the script console because a project can contain both the vision and perspective resources. Phil beat me to it 😛
