Operational Release Notes Should Name the New Failure Mode

Release notes become operationally useful when they name the new failure mode, not just the new feature.

The most useful line in a release note is often the one that tells operators how the system can now fail differently than before.

Notes should answer

• What new condition can go wrong?
• What evidence would reveal it early?
• What should the operator validate after rollout?

Use the changelog, security docs, and examples to evaluate new failure modes in each release.
