New in this release

A targeted patch for /bbox admin delete.

• 🔺 Admin delete actually deletes the island now. Not instantly, but when the plugin runs its housekeeping or pure runs. Note that if there are live islands in the same region file, then it will remain in the deleted state until the region is clear. If you really need to delete the blocks, then use WorldEdit or manually remove them. In the next full release we'll add a cut to the Blueprint command to remove blocks.
• 🔺 Seed worlds (<world>/bentobox) are no longer created. The seed-world infrastructure (createSeedWorlds, removeSeedWorlds, the in-memory copies, the on-disk folders) is gone. Any stale <world>/bentobox folders left over from earlier versions are safe to delete manually. These were not doing anything recently except taking up space.
• 🔺 API: GameModeAddon#isUsesNewChunkGeneration() is deprecated for removal. Existing addons that override it keep working (the value is simply ignored) but will see a deprecation warning. Remove the override at your convenience.

Internal cleanup that ships with the fix:

• Removed DeleteIslandChunks, IslandChunkDeletionManager, CopyWorldRegenerator, the bentobox-deleteIsland MultiLib subscriber, and the IslandDeletion DB recovery loader.
• WorldRegenerator slimmed to just regenerateChunk(Chunk); WorldRegeneratorImpl is now a small Bukkit-only delegate to World#regenerateChunk(int, int) used by CleanSuperFlatListener.
• IslandDeletionManager#inDeletion(Location) now queries live island state (Island#isDeletable()) instead of a side-channel HashSet, so it can never drift out of sync.

Compatibility

✔️ Paper Minecraft 1.21.5 – 26.1.2 ✔️ Java 21+

Upgrading

1. As always, take backups just in case.
2. Stop the server.
3. Replace the BentoBox jar with this one.
4. Restart the server.
5. (Optional) Delete any stale <world>/bentobox folders in your world container — they are no longer used.
6. You should be good to go!

🔺 Reap timing. When /bbox admin delete finishes, the player's blocks are still on disk; the island is just marked deletad. The actual region files come out on the next housekeeping sweep (default: 24 h). If you need immediate cleanup, run /bbox admin purge deleted after the delete. But again, it will only be removed if the region files are clear.

Legend

• 🔺 special attention needed.
