Horizon 2026.10.18.08: Clients keep the light the server sends and 5 more changes — release notes

· v2026.10.18.08 · c1b4ccd571 · 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

  • Structures: honour a carried mod's start and placement rules (#820)
  • Region files: write each saved chunk in place, as vanilla's RegionFile (#827)
  • Brewing stands tick in the level's block entity ticker list (#828)
  • Block entity animations: read the drawn block entities only when they change (#829)
  • Clients keep the light the server sends; the server sends light updates (#824)

Fixed

  • Paletted container access: one palette probe per write, dispatched unpack (#761)
