Server Admin Migration Guide
- MAJOR: Block ID flattening breaks all plugins using numeric IDs
- All commands using numeric IDs must be updated to namespaced IDs
- World conversion required - large worlds may take significant time
- Back up everything before upgrading
- Most plugins need updates for the new command system
- Phantom spawning may need to be managed via gamerule
Known Issues
- World conversion can take a long time for large worlds
- Some chunk errors may occur at old/new chunk boundaries
- Phantom spawn rate may be too aggressive for some players
