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.
