Horizon 2026.10.18.12: Region writer, paletted containers — release notes

· v2026.10.18.12 · 4f9df73831 · 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

  • Region writer: encode and compress chunks on helper threads (same bytes) (#860)

Fixed

  • Paletted containers: build palettes without hashing (#859)

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.
