Rule: Writing release notes

Goal

Turn a list of merged PRs into release notes a customer would actually read. The PRs say what work happened; the release notes say what changed for the user. Most release notes fail by listing the work ("Refactored billing service") instead of the change ("You can now switch plans mid-cycle without losing prorated credit"). Fix that.

Process

1. Receive input — a list of merged PRs (titles + descriptions), a git log range, a draft changelog, or a Linear / Jira label.
2. Ask clarifying questions to set audience, tone, and grouping.
3. Triage — separate user-visible changes from internal work. Internal work goes in "Under the hood" or gets cut.
4. Draft in the structure below.
5. Review with the user. Revise. The first draft is usually too long.

Clarifying Questions

Pick from these. Ask 3–4 max.

Audience — who reads this?

• A. End users (the people who use the product)
• B. Customers (the people who pay)
• C. Internal stakeholders
• D. Cross-team eng (other teams in the company)

Tone — match it to the audience and the product's voice.

• A. Plainspoken, period-ending. Like a colleague's email.
• B. Excited (real launches, big features). Use sparingly.
• C. Operational (status / fixes / maintenance).

Length

• 1. Headline-only (one paragraph for the changelog page)
• 2. Per-feature paragraphs (a digest email)
• 3. Full announcement (one section per feature with detail)

Grouping

• A. By area / surface (Billing, Dashboard, API)
• B. By impact (New, Improved, Fixed)
• C. By the named release / version

Output Structure

# <Release name or date>

<TL;DR — one sentence, three things max.>

## Highlights

- <Bullet — the change in one line, user-facing.>
- <Bullet>
- <Bullet>

## What's new

### <Feature name>
<One paragraph in the brand voice. Specific nouns, active verbs, what the user can now do.>

### <Next feature>
…

## Improvements

- <One-liner each, ordered by user impact.>



 



 



 

Voice rules

• List the feature, not the work. "You can now switch plans mid-cycle" beats "Refactored the billing service".
• Specific nouns. "Stripe, Adyen, Braintree" beats "all major payment providers".
• Active verbs. "Adds", "ships", "fixes" — not "facilitates", "enables", "unlocks".
• No marketing buzzwords. No "unlock", "empower", "leverage", "seamless", "next-generation", "AI-powered".
• Numbers when you have them. "30% faster" beats "much faster".
• One emoji per row max if your brand allows them at all. None in headlines.
• Period-end declarative. No question headlines. No exclamation drama.

Target Audience

Whoever you picked in Q1. If end users, write like a colleague explaining a change. If customers (paying), include the "why this matters for your team" thread. If internal, use the team's jargon — and skip what they already know.

Tiny worked example

PR list (input):

• #842 "Refactor billing service to support mid-cycle plan changes"
• #847 "Add prorated credit calculation"
• #851 "Fix Safari 17 crash on /projects/edit"
• #855 "Bump Stripe SDK to v17"

Output (excerpt):

Switch plans mid-cycle without losing credit

You can now upgrade or downgrade your plan in the middle of a billing period. Any unused time on your old plan is converted to prorated credit and applied to the new one — no support ticket needed.

Fixed

• Editing a project name no longer crashes Safari 17.

Note what disappears: the SDK bump (irrelevant to the user) and the "refactor" framing (internal). What survives is the user-visible change with a specific verb.

Anti-patterns

• One bullet per PR, copy-pasted from the title. PRs aren't release notes.
• "We're excited to announce…" The reader doesn't care that you're excited.
• "Multiple bug fixes and improvements". Name three of them, by impact.
• Hiding a breaking change in "Under the hood". Breaking changes get their own callout at the top.
• Release notes longer than the feature they describe. Cut by half.

Output

• Format: Markdown (.md)
• Location: tasks/release-notes/ or wherever your team keeps them.
• Filename: <YYYY-MM-DD>-<release-name>.md

Final instructions

1. Always ask the clarifying questions first. The same PR list produces different notes for end users vs. exec audiences.
2. Read your draft aloud. If a sentence sounds like a press release, rewrite it.
3. Cut at least 30% on the second pass. Most first drafts are too long.
