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

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.
