{{About|the <code>version.json</code> file in ''Minecraft'' [[Minecraft:client.jar]] and [[Minecraft:server.jar]]|the <code>''<game version>''.json</code> used by the launcher|client.json}}
{{exclusive|java}}

<code>'''version.json'''</code> is embedded within <code>[[Minecraft:client.jar]]</code> in <code>[[Minecraft:.minecraft]]/versions/''<version>''</code> and <code>[[Minecraft:server.jar]]</code> since [[Minecraft:18w47b]]. It offers some basic information about the version's attributes.

The {{cmd|version}} command also presents the same information on the [[Minecraft:server]] side, and the {{keys|F3+V}} [[Minecraft:debug hotkey]] on the client side.

== JSON format ==
