Added

• entity-clear.protect-items: dropped items the entity clear leaves alone. named keeps items renamed in an anvil (on by default), enchanted keeps enchanted items and books, materials takes a list such as [DIAMOND, NETHERITE_INGOT].
• entity-clear.warn-before-clear.bossbar: a boss bar that counts down to the automatic clear, next to the chat warning. Off by default. The text is auto-clear-bossbar in every language file.

Changed

• Renamed dropped items are no longer cleared by default. Set protect-items.named: false for the old behaviour.

Existing servers: the new options are not added to an existing config.yml. Without them only the named-item protection applies.
