## PlaceholderAPI Support
You can now use PlaceholderAPI in the customizable messages in `config.yml`.
[PlaceholderAPI available placeholders](https://api.extendedclip.com/all/)
## 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.
