Easily Access Related Record Data in Autolaunched Flows with Triggers
Now in autolaunched flows with triggers, you no longer need to create Get Records elements to find associated records and retrieve data from them. Instead, when you configure flow elements and resources, you can easily drill down to the field values of a global or record variable's associated records. For example, in a Decision element, drill down from $Record to Account ID to Customer Priority.
