New change to Variables
Instead of using % for variables. You will need to use < > (for PlaceholderAPI, use the regular %).

Worlds
You can now block or allow /dupe in specific worlds.

Changes to Blacklist
You are now able to whitelist or blacklist worlds or items. Whitelist blocks everything and allows the worlds/items in the list. Blacklist does the opposite.
