ItemBlocker

[1.2.0] - 2026-10-18

Added

• Support for Minecraft 26.1.1, 26.1.2, 26.2 and 26.3. The same jar runs on every version from 1.21 to 26.3.
• Blocked armor can no longer be put on with the offhand swap key (F) over an armor slot, by dragging it onto an armor slot, or by a dispenser.
• Item names in commands accept the minecraft: prefix, for example /ib block minecraft:tnt.

Fixed

• /ib block enchantment and /ib block potion with in:<preset> reported success when the preset did not exist. They now report that the preset was not found.
• Presets named like a command word (for example list or set) could not be shown, edited or deleted.
• /ib preset create accepted names that broke presets.yml (for example [x] or #x) or clashed with command words. Preset names now use only a-z, 0-9, _ and -.
• Tab completion listed hundreds of LEGACY_* materials, and commands accepted them along with non-item materials such as WATER, which can never be blocked.
• itemblocker.list now allows /ib list presets, /ib list enchantments and /ib list potions, and itemblocker.info allows /ib show enchantment and /ib show potion, as their permission descriptions say.
• Blocked smithing, enchantment and potion effect messages are now translated in German, Spanish, French and Italian. Existing language files are not overwritten, so delete languages/messages_<lang>.yml to get the new texts.
• Hangar releases now list Paper 26.x versions, and Modrinth releases list every version from 1.21 to 26.3 instead of stopping at 26.1.

Compatibility

• Requires Java 21+ (Minecraft 26.x servers require Java 25)
• Supports Folia / Paper / Purpur / Spigot
• Minecraft 1.21 to 26.3
