This article is about the version.json file in Minecraft client and server jars since 18w47b. For the <game version>.json used by the launcher, see client.json.
This feature is exclusive to Java Edition.
version.json is embedded within client.jar in .minecraft/versions/<version> or server.jar since 18w47b. It offers some basic information about the version's attributes.
