Added

• Automatic database backups (SQLite only)

Changed

• More robust item serialization. Ender chest contents are now stored using stable ItemStack.serializeItemsAsBytes / deserializeItemsFromBytes API instead of the previous experimental data-component approach
• Existing data is safe. Chests saved by older versions are still read correctly and are transparently upgraded to the new format the next time they are saved (lazy migration). No manual action is required
