• Fixes for serious issues. Defined in the policy as correctness, stability, or security issues, data corruption/loss, significant performance regressions, breaking working and widely used functionality, or an inability to detect and debug production issues.
• Other approved changes. These changes must be gated behind a disabled-by-default feature flag unless there is a strong justification not to.

✅ PR #155294 is compliant with backport policy

Confidence: high
Backward compatible: true
Explanation: The PR changes only pkg/testutils/release/cockroach_releases.yaml, which is considered a non-production file as it fits under the pattern associated with 'testutils/'. Since the PR consists solely of non-production changes, it is exempt from the standard backport policy requirements. Additionally, the PR body explicitly mentions a release justification targeted for test-only updates, further aligning it with the backport policy for non-production changes.
