Open your Onboarding agent from code once per visitor

Programmatic triggers can now open your Onboarding agent only once for each visitor. Turn on Fire only once per visitor when editing a "Trigger from your code" trigger. After the trigger has opened the agent for a visitor, your code's later calls for that visitor are ignored, including in other tabs and on later visits.

This suits announcements: call the trigger whenever a visitor reaches a new feature, and each visitor sees the walkthrough once without you keeping track of who has seen it. Identified visitors are recognised across devices. See programmatic triggers for the details.
