Release Notes

Write release notes for a new version that match your product's established voice. The hard part is filtering hundreds of commits down to what users can see and writing it like you're telling a friend what changed — not reciting a git log.

When to use

• Preparing a release / writing a changelog / updating the docs-site release notes.
• NOT for internal dev changelogs (those keep refactors/CI/deps).

Inputs (ask if missing)

• Version (e.g. 2.1).
• Release branch (what's shipping) and base branch (what's live now). Default base = origin/release or origin/main.
• Voice reference — 2–3 past release notes to match format/tone. If none, ask for the docs-site URL or infer a simple flat-bullet style.

Process

digraph rn {
  "Identify branches" [shape=box];
  "Diff all commits" [shape=box];
  "Read planning docs" [shape=box];
  "Categorize (user-facing only)" [shape=box];
  "Draft in product voice" [shape=box];
  "User review" [shape=diamond];
  "Finalize + suggest doc updates" [shape=box];
  "Identify branches" -> "Diff all commits" -> "Categorize (user-facing only)";
  "Identify branches" -> "Read planning docs" -> "Categorize (user-facing only)";
  "Categorize (user-facing only)" -> "Draft in product voice" -> "User review";
  "User review" -> "Finalize + suggest doc updates" [label="approved"];
  "User review" -> "Draft in product voice" [label="revise"];
}

1–2. Branches + full diff

git fetch origin, find the release and base branches, then pull every commit (git log --oneline base..target), paging in chunks of ~200. For 500+ commits, fan out parallel agents over chunks.

3. Categorize — user-facing ONLY

Sort commits into buckets: New features · Plan/limit changes · Section/area improvements · UX improvements · <domain area> · Bug fixes. Skip entirely: refactors, tests, CI/CD, dependency bumps (unless user-visible), docs, dev tooling, merge commits, monitoring/logging, backend internals.

4. Draft in product voice

Default format — a flat bullet list under a version header, features first, bug fixes last:

## X.Y (Mon DD, YYYY)
- [Biggest new feature first]
- ...
- Fixed a bug where [specific notable fix]
- Other minor bug fixes and improvements

Writing rules:

1. Start every bullet with an action verb: Added…, Improved…, Increased … from X to Y, Fixed a bug where….
2. Exact numbers for limit changes ("from 3 to 5", never just "increased").
3. Tag plan-gated features (e.g. (Pro plan)); add (learn more) + link for major ones.
4. User-facing language — "your website", not "the DOM"; name features the way users see them. No internal tech names (frameworks, datastores, infra).
5. One sentence per bullet (max two). 10–20 bullets for a major release, 3–5 for a patch.
6. Bundle minor fixes; give 2–4 specific fixes + one catch-all (Other minor bug fixes and improvements).
7. No emoji. Match the version header style of past notes (e.g. 2.1 not v2.1).
8. Tone: warm, confident, direct ("Added" not "We've added"); focus on user benefit ("loads up to 90% faster") not implementation ("migrated to static generation").

5. Finalize

Output: (1) the formatted notes ready to paste, (2) support/docs articles that likely need updating, (3) suggested new articles for major features.

Common mistakes

• Including internal changes (refactors, deps, CI) — users don't care.
• Vague limit changes without the before/after numbers.
• Implementation language instead of user benefit.
• Listing every bug fix instead of bundling.
• Drifting from the established header/tone — always match past notes.
