Horizon 2026.10.15.15: Agent control and 2 more changes — release notes

· v2026.10.15.15 · b8ed3a113a · GitHub ↗

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

New

  • Agent control: the widget tree of every screen, click and set by id (#349)
  • Agent control: read and set every option by key (#350)
  • Agent control: wait for a state, and the log of what happened (#351)

Fixed

  • perf(client): share parsed block and item models (#330)
  • Cache animated sprite mip chains within an 8 MiB budget (#341)

Known issues

  • Sprint-jumping has been reported as broken, but we couldn't reproduce it. If it happens to you, describe it in #horizon-bugs on Discord.

Thanks to @rdbtCVS.

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.
