Horizon 2026.10.18.26: Entity tracking, guest ticks, chunk batches and 5 more changes — release notes

· v2026.10.18.26 · a9bcaa6ed5 · GitHub ↗

The launcher installs and updates the game — no need to grab these archives by hand. You need your own Minecraft: Java Edition.

Binaries removed (licence cleanup, see #6741); tags and source remain.

New

  • Terrain: occlusion culling of solid sections that pays for itself (Vulkan) (#939)
  • Structures: Repurposed Structures' three rule tests (matter phase, piece-origin distance, height) (#919)
  • Carry: Repurposed's rule tests as the game's, and minecraft:chain as iron_chain (#920)
  • Structures: Repurposed Structures' mineshafts, laid out under the terrain (#922)
  • Carry: Better Dungeons' small Nether dungeon, as YUNG's jigsaw (#923)
  • Carry: vertical_distance_from_start_piece is a dead field, not a lost rule (#924)
  • Structures: Moog's trial spawners and vaults, without the templates' saved state (#926)
  • Structures: Better Desert Temples' placeholder blocks (suspicious sand, sherds, traps) (#929)
  • Structures: Better Dungeons' small dungeons keep one or two chests (#930)
  • Structures: Lithostitched's block swaps (Overhauled Village), with the shared properties (#932)
  • Chunk packets: pack paletted containers a long at a time (2.3x faster from_values) (#915)
  • Chunk batches: encode each column once a tick, its new sections on warm-up threads (#934)
  • Guest ticks: count per-tick statistics without making strings, date criteria only when granted (#914)
  • Entity tracking: check a pair again only when one side moves, as vanilla's ChunkMap (#927)

Fixed

  • Villagers, traders and golems never despawn for distance (#917) (#942, fixes #917)

Install or update it from the Horizon launcher: it installs new versions by itself. New here? Get the launcher at https://playhorizon.dev. You need your own copy of Minecraft: Java Edition.
