New Features

• oras is compliant with OCI image-spec v1.1.0 and distribution-spec v1.1.0
• Introduce brand-new default terminal experience
  • Show live progress for the following commands:
    • oras copy

    • oras blob push
  • The new terminal experience can be turned off via the preview flag --no-tty

• Support X.509 mTLS authentication with OCI registries

Preview Features

• BREAKING CHANGE Registries supporting Referrers API prior to distribution-spec v1.1.0-rc4 will fall back to Referrers tag schema, causing unexpected results of oras attach and oras discover commands
• Introduce --platform to oras attach for better multi-arch attaching experience, which allows adding referrer artifact to a specific sub-platform
• Re-purpose the flag --recursive of oras cp from extended copy to copy an artifact or a multi-arch image and its referrers
• Promote --image-spec to a preview flag from experimental

Experimental Features

• BREAKING CHANGE oras discover shows tree view output by default
• Introduce formatted output via --format by implementing the specification
  • Formatted output is available to the following commands:
    • oras pull
    • oras push
    • oras attach
    • oras discover
    • oras manifest fetch
  • Examples:
    • --format json to print operation result as a JSON object
    • --format "go-template={{ .digest }}" to print the digest of the manifest using Go template
      • Template can also be specified by --template
• Introduce oras resolve to get the digest of an artifact

Deprecation

• oras discover: --output is marked as deprecated and succeeded by --format
