Version Support

Current server-plugin release: 1.1.0 for both Free and Pro.

Server compatibility

Component	Supported range
Paper	1.21.7 and newer
Java	21
Purpur	Expected on builds based on a compatible Paper API; Paper remains the tested target
Spigot	Not supported

Free and Pro share the same server compatibility and optional-client integration.

The plugin declares api-version: 1.21.7, so servers older than 1.21.7 should reject it rather than starting with undefined behavior.

Client compatibility

Vanilla players need only a Minecraft version compatible with the server and the generated resource pack.

The client mod must match:

• the player's Minecraft version;
• the correct mod loader and dependencies.

Current client-mod release: 1.1.0. Plugin and client mod 1.1.0 use protocol 4. Older client builds are treated as incompatible and safely fall back to vanilla playback.

If the mod is incompatible, the player uses vanilla resource-pack playback instead.

Updating the plugin

1. Back up the plugin data directory.
2. Stop the server.
3. Replace the JAR and update Paper/Java if required.
4. Start and review console output.
5. Run /radio zip.
6. Run /radio reload.
7. Test one vanilla and one modded client when available.
