CMI mode didn't work — v1.4 ran the wrong command and CMI rejected it. v1.5 runs the correct one (cmi:spawn <player>, with spawn <player> as fallback). mode: cmi now teleports your players as expected.
Smaller jar (986 KB → 16 KB)
The MiniMessage / Adventure libraries are no longer bundled inside the jar. The server downloads them once on first start into its shared libraries/ folder and reuses them for every plugin that needs them.
You don't need to do anything. Drop the jar in, start the server, done. Internet required on first boot only (subsequent starts use the cached copy).
Air-gapped server? Copy the libraries/net/kyori/ folder over from any machine with internet.
What changed under the hood
CMI dispatch command corrected.
Adventure + MiniMessage moved out of the jar, declared in plugin.yml under a libraries: block (Bukkit LibraryLoader, Spigot/Paper/Folia 1.18+).
Shading removed entirely.
Drop-in replacement for 1.4. No config changes. Compatible with Spigot, Paper, Purpur & Folia 1.18 – 1.21+.
