• Draft comment:
  Major update from v1 to v6; ensure that all input parameters (like 'go-version') are still valid and no breaking changes affect your workflow. Please review the v6 release notes.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50% This comment is asking the PR author to ensure that input parameters are valid and to review release notes, which falls under asking the author to double-check things and ensure behavior is intended. This violates the rules.
