version_manifest.json

This feature is exclusive to Java Edition.
 

version_manifest.json and its variant version_manifest_v2.json are files containing a list of Java Edition versions from piston-meta.mojang.com. It lists Minecraft versions available in the launcher.

If a version is absent from this list, it is considered unavailable from the launcher.

This list is updated every time Mojang Studios publishes a new version for Minecraft: Java Edition.
