Very little has changed from the 2016-17 requirements, mostly minor changes to the text.
The Arrow of Light "Scouting Adventure" pin had the most text changes, with references to "Boy Scout troop" revised to just "troop." The "Maestro" adventure pin now refers to "his or her homemade musical instrument."
Two badges were renamed. The Webelos/Arrow of Light elective is now "Sports," renamed from "Sportsman," and the Arrow of Light required pin is now "Outdoor Adventurer," renamed from "Outdoorsman."
