Released 2023-06-12
Minecraft 1.20.1 needs Java 17
Modded Minecraft currently revolves around 1.20.1. NeoForge debuted here, and it has built up the biggest mod library of any version since 1.16.
Java version required
17or newer
An older Java will not start it. A much newer Java normally does, but that is up to the server software rather than Minecraft.
Availability
Paper is available for 1.20.1
It accepts Bukkit / Spigot / Paper plugins.
Will the file I downloaded work?
Mods and plugins are two different things that both come as a .jar. Use the wrong kind and there is usually no error: the server boots and the content is simply missing.
running on Paper
No. Forge is a mod platform and Paper runs plugins — two separate systems that just share a file extension. Nothing loads, and you get no warning.

Things to know about this version
It is the only version where Forge and NeoForge are both truly active, and that is more hazard than help — a mod made for one will not load on the other, and 1.20.1 mod pages are not always clear which one they mean. Choose your pack's loader before you download a single mod, then check every mod against it.
