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
- No AI: one switch that turns off agent control (socket, horizon-ctl, both MCP servers) (#1342)
- horizon-ctl: every player action in the one table (worlds, LAN, friends, options pages...), with a generated reference (#1343)
This is an alpha build: launchers on the Alpha channel (Settings, Updates) install it now; Stable gets it in the next daily update if it holds up.
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.
