writing-release-notes-as-postmortem

To write postmortem-style release notes, you create severity-sorted fix entries containing six specific fields: bug ID, user-visible symptom, code location, root-cause class, regression test, and commit SHA. This documents what failed, what changed, and how the fix is verified.

Structuring a changelog for a regulated security patch requires an executive summary with severity counts and coverage delta, strict avoidance of marketing language, and prior-release cross-links. This ensures traceability and audit-readiness for compliance requirements.

Yes, postmortem release notes handle mixed feature-and-fix patch releases, hotfixes, and stability updates. They focus on severity-sorted fix entries and deferred-issue tracking, ensuring all regressions are documented regardless of the release type.

Tracking deferred regressions involves listing unresolved issues separately within the changelog and including prior-release cross-links. This maintains a continuous audit trail across versions while clarifying which fixes are deferred from the current patch.

Stripping marketing language from hotfix release notes ensures the changelog remains an objective audit trail. It forces focus on the six per-fix fields, executive severity counts, and coverage delta, which are required for accurate postmortem analysis and compliance.

An executive summary for regression-fix release notes should include total fix counts, weighted severity metrics, and coverage delta. It provides a high-level postmortem overview of the release impact without using promotional language.
