min_format and max_format: [94, 1]

Supported versions & limitations

Verified Java dataset: 1.21.11

  • Only Java 1.21.11 is verified. Resource and data formats are different; metadata does not migrate pack contents.
  • This creator makes metadata only. Textures, recipes and other resources must be added separately. Overlays and older format imports are rejected.

Frequently asked questions

Why use two format numbers?

Since 1.21.9, pack compatibility supports major and minor versions using min_format and max_format.

Can this fix an incompatible recipe or texture?

No. Metadata declares compatibility; it does not convert pack content or validate every resource.
