Yes, restrictions were retired in Rule 4.0 with hub firmware 2.1.4: Rule 4.0: Retirement of Restrictions
However, it's still possible to do what you want (that's actually why they were retired: they were a less powerful, more confusing way to do what Rule Machine has been able to do since 4.0 and in most cases even 3.0). What you'll need to do use use a conditional in your rule actions somewhere, either an IF around your actions or just a simple conditional action on the action itself. The post above may give you some ideas, and if you're not sure, feel free to post your rule here. Good luck!
