SlimefunCore4 — Changelog

Build 2670 — 2026-05-19

🟢 Addon Manager

• Multi-version addon URLs via addons.<key>.versions per SF4 build tag
• Auto-detects server Minecraft version on startup, shows only compatible addons
• Version-specific cloud-sync URL support via cloud-sync.version-urls
• /addon list shows server version, active build tag, and hidden addon count
• Old single-URL config format still works — automatically upgraded on load
• Remote sync no longer overwrites local enabled / download toggles

🔵 Safety

• Addon JARs only deleted when explicitly disabled or removed via command
• Deletion queue, addon logs, and config backups kept across restarts

🟡 World Backup

• New WorldBackupService — backs up world, world_nether, world_the_end on shutdown
• Skips live lock files, checks disk space before starting, auto-purges old backups
• Configurable via slimefun.world-backup in config.yml

🔶 Dough Bridge Layer

• Added io.github.thebusybiscuit.slimefun4.libraries.bridge — 13 wrapper classes (SF4Items, SF4Colors, SF4ItemUtils, SF4InvUtils, SF4Patterns, SF4BlockPos, SF4DataAPI, SF4ChatInput, SF4Vein, SF4PlayerUtils, SF4TaskQueue, SF4Config, SF4Collections)
• 144 internal call sites migrated to bridge — future Dough updates touch 13 files, not hundreds
• Public API and storage types kept as direct Dough imports for addon compatibility
• No gameplay or behaviour changes
