This issue is related to the proposal of promoting maturity of experimental and preview feature commands and flags #1771

oras attach is currently marked as Preview. This command allows users to attach referrers to an image

Rationale for Promotion

Over recent releases, oras attach has demonstrated:

• Functionality completeness – The feature itself is straightforward and simple, which allows users to attach referrers to an image
• Stability – CLI syntax and output structure have remained consistent over multiple releases.
• Low maintenance overhead – No major breaking changes or regressions reported in recent cycles.

Given its maturity and stability, promoting oras attach to Preview will encourage broader adoption while signaling to users that the feature is nearing full stabilization.

Next Steps

• Update the feature mark for oras attach from Preview to Stable in CLI documentation and help text.
• Communicate the change in release notes for ORAS v1.3.0.
