The release of version v2.1 is built against the Paper API instead of the Spigot/Bukkit API! For Spigot use v2.0 instead!

Compatibility:
Paper announced that they are hard forking Spigot meaning that the APIs would slowly diverge starting in Minecraft version 1.21.4.
Spigot compatible releases will still exist but this way we guarantee to stay compatible with Paper and can use the more powerful API.
For details see the plugin compatibility table and our explanation how Paper/Spigot compatibility will work in the future.

New features:

• Support for capturing the output of blocking commands, including vanilla commands! Meaning it is now possible to use any server-side commands and use their respective outputs!
