1.18.2 Pre-release 1 (known as 1.18.2-pre1 in the launcher) is the first pre-release for Java Edition 1.18.2, released on February 18, 2022,^[1] which improves structure related tags and commands, updates data packs, and fixes bugs. This is the first pre-release released in 2022.

Tags

• Added following configured structure feature tags:
  • #dolphin_located: #ocean_ruin, and #shipwreck.
  • #eye_of_ender_located: stronghold.
  • #mineshaft: mineshaft, and mineshaft_mesa.
  • #ocean_ruin: ocean_ruin_cold, and ocean_ruin_warm.
  • #on_ocean_explorer_maps: monument.
  • #on_treasure_maps: buried_treasure.
  • #on_woodland_explorer_maps: mansion.
  • #ruined_portal: ruined_portal, ruined_portal_desert, ruined_portal_jungle, ruined_portal_mountain, ruined_portal_nether, ruined_portal_ocean, and ruined_portal_swamp.
  • #shipwreck: shipwreck, and shipwreck_beached.
  • #village: village, village_desert, village_plains, village_savanna, village_snowy, and village_taiga.

Dolphins

• Now pick the closest structure more accurately, regardless of structure type.

Bastion remnant

• Bounding boxes are now slightly more accurate to the shape of the structure.

/locate

• Now support tags, using # prefix to distinguish from normal IDs.
• The parameter is now a configured structure rather than a structure type.
  • For instance, it is now possible to use /locate village_desert or /locate shipwreck_beached.
• The old usage for structure categories is now done via tags.
  • For instance, /locate village is now /locate #village.

/locatebiome

• Now support tags, using # prefix to distinguish from normal IDs.
  • For instance, it is now possibile to use /locatebiome #minecraft:has_structure/igloo.

Data packs

• Increased data pack version from 8 to 9.
• It is now possible to add custom structures in experimental datapacks: the game now generates and stores data-driven configured structures.
  • Experimental datapacks can add new structure sets.
  • The feature field in location predicates now references a configured feature.
  • The exploration_map loot table function destination field is now a configured feature tag id.
  • The exploration_map loot table function no longer automatically sets the display name of the map.
• A lot of the cave generation is now configurable through data packs.
  • A new registry was added for Density functions (caves are created by combining those together).
  • Noise settings got a new field noise_router (and lost a couple of flags), see worldgen/noise_settings folder in the worldgen report.
  • Noise router wires data-driven parts of the cave generation with the rest of the code.

General

• Added a warning for users running Minecraft in a 32-bit environment in the main menu, because support for the 32-bit environment will end soon.
