BentoBox Changelog

[3.13.0] — 2026-04-04

New Release Highlights

• 🔺 Paper 26.1.1 (Minecraft 26.1.1) support — BentoBox now recognises Paper's new year-based versioning scheme (26.x.x) and no longer shows a compatibility warning. The version parser has been updated to handle the new getBukkitVersion() format. BentoBox remains fully compatible with Paper 1.21.5 – 1.21.11 servers.
• ⚙️ 🔡 PAUSE_MOB_GROWTH protection flag — Minecraft 26.1.1 introduces golden dandelions that can pause or unpause baby mob growth. A new island protection flag lets island owners control who can use this feature. Defaults to members only. Supports both main-hand and off-hand interactions.
• 🔡 MiniMessage locale migration — All locale files have been migrated from legacy §/& colour codes to Paper's MiniMessage format (<green>, <bold>, etc.), with full backward compatibility for existing custom translations. The format of MiniMessage messages can be found here.

Compatibility

✔️ Paper Minecraft 1.21.5 – 1.21.11
✔️ Paper Minecraft 26.1.1

2. Stop the server.
3. Replace the BentoBox jar with this one.
4. Restart the server.

🔡 Locale migration note: All 23 locale files have been migrated to MiniMessage formatting. If you have customised locale files, BentoBox will still handle legacy §/& codes, but regenerating your locale files is recommended to take advantage of MiniMessage features.

New Features

🔺 Paper 26.1.1 Support

[PR #2897]

Paper has adopted a new year-based versioning scheme starting in 2026 (e.g., 26.1.1 instead of 1.21.12). BentoBox's ServerCompatibility version parser has been updated to handle the new getBukkitVersion() format (26.1.1.build.14-alpha), which includes a .build.N suffix that the old parser couldn't strip. V26_1_1 has been added to the supported versions enum as COMPATIBLE.

BentoBox continues to compile against the Paper 1.21.11 API and remains compatible with all currently supported 1.21.x versions.

⚙️ 🔡 PAUSE_MOB_GROWTH Protection Flag

[PR #2898] [PR #2900]

Minecraft 26.1.1 added the ability to use a golden dandelion on a baby mob to pause or resume its growth. A new PAUSE_MOB_GROWTH island protection flag controls who can do this. The flag defaults to members and above; visitors are blocked.

The listener checks PlayerInteractEntityEvent for a player holding GOLDEN_DANDELION in either hand targeting a baby Ageable mob. Uses Enums.getIfPresent for the flag icon material so BentoBox remains backward compatible with 1.21.x servers where the item doesn't exist.

Translations added to all 23 locale files.

🔡 MiniMessage Locale Migration

[PR #2894] See: https://docs.papermc.io/adventure/minimessage/format/

All locale files have been migrated from legacy §/& colour codes and ChatColor API usage to Paper's native MiniMessage format. This enables richer formatting (gradients, hover text, click events) and aligns with Paper's direction of deprecating legacy formatting.

Backward compatibility is maintained: existing custom locale files using legacy codes will continue to work. Multiple follow-up fixes ensured edge cases were handled correctly:

• Mixed MiniMessage/legacy content no longer shows raw tags
• Multi-line translations preserve newlines correctly in panel lore
• Flag panel rank colours render correctly
• Conversation prompts display properly
• Rank display maintains backward compatibility with legacy locale files

Bug Fixes

Fix ItemStack quantity > 99 crash during serialization

[PR #2895]

Fixed a crash when serialising an ItemStack with a quantity greater than 99. The quantity is now clamped to a valid range before serialization.

Deduplicate lock/ban notification messages

[PR #2892]

Fixed an issue where players would receive repeated lock/ban notification messages when standing at an island boundary, causing chat spam.

Fix hex color codes breaking subsequent legacy color codes

[PR #2893]

Fixed a bug where hex colour codes (e.g., &#FF0000) would corrupt subsequent legacy & colour codes in the same string.
