Migration Guide

From 1.3 to 1.4

Automatic Migration

When you first start v1.4, the plugin will:

1. Detect outdated config (v1) and messages (v1)
2. Create backups: config.yml.backup-v1 and messages.yml.backup-v1
3. Merge your customizations with new defaults
4. Log all migrated settings to console

Manual Steps (Optional)

None required! Everything is automatic.

Breaking Changes

1. Blacklist Removed: If you relied on blacklist behavior, adjust your whitelist:
   • Old: Blacklist = entities to clear
   • New: Whitelist = entities to protect, everything else clears

Reverting

If you need to revert:

1. Stop server
2. Restore from backup: cp config.yml.backup-v1 config.yml
3. Edit config-version: 1 in config.yml
4. Start server with old plugin version
