New item/ node category (6 nodes):

• item/inspect – read all properties in one node
• item/modify – set name/lore/amount/damage/model data, returns new ItemStack
• item/enchant – GET/SET/REMOVE/HAS mode for enchantments (uses Registry API)
• item/compare – similar vs identical comparison between two ItemStacks
• item/pdc – GET/SET/HAS/REMOVE on ItemStack PersistentDataContainer

New paper/ nodes:

• paper/entity_pdc – GET/SET/HAS/REMOVE on Entity PersistentDataContainer
• paper/inventory_slot – GET/SET item in specific inventory slot
• paper/inventory_held – GET/SET player's main hand item
• paper/player_get_food – companion to player_set_food
• paper/entity_teleport – companion to player teleport
• paper/player_uuid – get UUID string from player
• paper/entity_uuid – get UUID string from entity
• paper/get_player_by_uuid – look up online player by UUID

New data/ nodes (Map/Dictionary):

• data/map_create, map_set, map_get, map_remove, map_contains, map_keys

New trigger/ nodes:

• trigger/player_move – PlayerMoveEvent (BLOCK mode by default)
• trigger/item_pickup – EntityPickupItemEvent filtered to players

API fixes:

• SendActionBarNode: BungeeCord API → p.sendActionBar() + Adventure
• ChatTriggerNode: AsyncPlayerChatEvent → AsyncChatEvent (Paper)
• EntityEffectNode: PotionEffectType.getByName() → Registry.EFFECT
• EntityNameNode: setCustomName(String) → customName(Component), naive & replacement removed
• MaterialMetaNode: ChatColor + setDisplayName/setLore → Adventure API; marked @deprecated
• PlayerDeathTriggerNode: getDeathMessage() → deathMessage() Component
• SpawnEntityNode: EntityType.valueOf() → Registry.ENTITY_TYPE

Port type updates (any/object → item_stack):

• PlayerGiveItemNode, DropMaterialNode, InventoryContainsNode, InventoryRemoveNode, EntityEquipmentNode, InventoryClickTriggerNode

DropMaterialNode/InventoryContainsNode/InventoryRemoveNode: split single "any" port into explicit item_stack + string ports

Other fixes:

• CreateLocationNode: yaw/pitch promoted from property-only to input ports
• EntityDamageNode/EntityEffectNode/EntityAINode/EntityNameNode: property default values corrected from string literals to proper primitives
• NodeRegistry: papi/ prefix added to SOFT_DEP_PREFIXES map so PlaceholderAPI required-plugin warning appears in node palette
