Summary
ORAS CLI 1.3.0 is compliant with OCI distribution-spec 1.1.1 and adds oras backup and oras restore for moving artifacts between registries and local OCI layouts. It also promotes several attachment features to stable and adds richer multi-architecture manifest management.
Why it matters
Portable artifact backup and clearer OCI metadata improve resilience and reproducibility in container, model and software supply chains.
