Release notes are a raw list of every PR title, often 250+ lines of fix(mobile): … and refactor: …. Nobody can tell what actually changed. In the app, stable users saw no notes at all, and nightly users saw the last 8 PR titles as bullets.

Now each stable and nightly release opens with a short note:

1. A header computed by code: "v0.1.4 · 275 changes from 22 contributors".
2. A summary from GPT-6.1 Terra (low reasoning): one "Highlights" paragraph of the notable features, then up to 10 fixes. It covers web, desktop, and server only, so commits whose scopes are all mobile are left out.
3. GitHub's full list, folded under <details>.

In the desktop app, the update popover now shows notes on every channel. Each release is the highlights paragraph plus the counts, which link to GitHub. The offered release shows how long ago it shipped ("3h ago"), read from the update feed's releaseDate. The feed dates only the offered release, so older stacked nightlies show their build day from the version ("1d ago"). Fixes stay on GitHub, so several stacked releases stay short. Older releases without a summary keep the old list.

Generation is one continue-on-error step in the release job. If it fails or there is nothing to summarize, it writes no file, and the release uses GitHub's generated notes as before. It costs about $0.01 to $0.04 per release. It uses the OPENAI_API_KEY repo secret, which is already set.

GitHub release, before	GitHub release, after

In the app (packaged Linux build, mock update feed)	Popover, dark, 3 releases stacked

The GitHub images are GitHub's own Markdown rendering of v0.1.3..main, and the "after" notes come from a real run of the script. The in-app image is a locally built AppImage pointed at the repo's mock update server.

How the model and prompt were picked

We compared Haiku 5.5, Sonnet 5.5, GPT-6.1 Sol, and GPT-6.1 Terra, all on low reasoning, over a stable range, the current stable range, and a nightly. Over several prompt rounds, we added rules and gave the models the first 300 characters of each PR body. Commit subjects alone hide fixes like "packaged server ships zod", which was really a desktop crash on startup. Terra followed the style rules as well as Sol, at half the price. Haiku got facts backwards, and Sonnet ignored the style edits.

Proof: focused tests for the summary parser, the Discord cut, contributor counting, and the mobile filter. The parser tests fail on main. vp run check:changed passes, and actionlint finds nothing new. Real script runs on v0.1.3..main and a nightly range worked, and a forced API failure wrote no file. A packaged AppImage showed the popover with stacked notes. The release workflow itself first runs on the next nightly.

Council review

Rounds: 2 on the pipeline, 3 on the popover design

Delegate	Pipeline R1	Pipeline R2	Card R1	Card R2	Card R3
Claude Opus 5.5	6/10	9/10	5/10	8/10	9/10
Muse Wonder Full	6/10	9/10	5/10	8/10	9/10
Codex GPT-6.1 Sol	6/10	9/10	6/10	9/10	9/10

The pipeline review moved generation into the release job, so a failure can never block the release. The card review moved the body to text-xs, replaced the popover's inherited text-balance with text-pretty, and replaced separators with spacing.

Reviewed with sol-loop: 2 rounds with GPT-6.1 Sol. Sol verdict: approved

🤖 Generated with Claude Code. Created with Claude Opus 5.5 in T3 Code. The eval runs used GPT-6.1 Terra, GPT-6.1 Sol, Claude Sonnet 5.5, and Claude Haiku 5.5.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Release notes gain automated summaries and release ages, with fallback to GitHub-generated notes. The update-details popover also becomes standard beyond nightly builds; that default experience needs human confirmation.

Walkthrough

The release workflow can generate notes for non-preview releases with a previous tag. Desktop, web, and Discord components process the summary and folded full changelog. Desktop update notes include release dates, summary text, and statistics when available.

Changes: Release notes flow

Layer / File(s)	Summary
Summary content and filtering scripts/generate-release-notes.ts, scripts/generate-release-notes.test.ts	The generator builds model input from commits and pull-request data. It excludes commits whose scopes are all mobile, Android, or iOS from the summary, counts contributors, and formats the release header. Tests cover contributor counts and scope filtering.
Fetch release data and write notes scripts/generate-release-notes.ts	The CLI reads commits between tags, fetches pull-request data and GitHub’s full changelog, and requests a model summary. It writes assembled notes when summary text is available.
Connect generation to the release job .github/workflows/release.yml, docs/operations/release.md	The release job checks out full history and runs the generator for non-preview releases with a previous tag. It uses the generated file when present and requests GitHub-generated notes otherwise. The release guide documents the generation step and fallback.
Parse and display generated notes packages/contracts/src/ipc.ts, apps/desktop/src/updates/DesktopUpdates.ts, apps/desktop/src/updates/releaseNotes.ts, apps/desktop/src/updates/releaseNotes.test.ts, apps/web/src/components/sidebar/SidebarUpdatePill.tsx, apps/web/src/components/sidebar/SidebarUpdatePill.browser.test.tsx, apps/web/src/components/sidebar/SidebarUpdateReleaseNotes.tsx	The desktop contract and parser support summary fields and release dates. The sidebar displays release notes for any update channel and shows summary content and release age when available. Tests cover parsing, release dates, and the popover label.
Format release notes for Discord scripts/notify-discord-release.ts, scripts/notify-discord-release.test.ts	The Discord formatter links pull-request references in the summary and adds a link to the full changelog when notes contain a folded section. A test covers the formatted announcement.

Merge Risk: Low · up to f16a6

Some release notes may show under the wrong version or fail to summarize a sparse release. These are bounded issues, but the version label and summary instructions should be corrected before relying on the new presentation.

Cover the stable-channel popover path.

The browser tests use only nightly update states. A nightly-only regression would therefore pass while removing release notes from stable releases. Extend the existing popover test with a stable-channel state and assert that its release notes open.

- Around line 134-135: Update the release-note extraction around summaryEnd to
use extractReleaseNoteSummary only when the note has the generated
version-and-stats header; otherwise continue through legacy extraction so
handwritten details disclosures do not replace fix bullets with introductory
prose.

Review comments at
@apps/web/src/components/sidebar/SidebarUpdateReleaseNotes.tsx:
- Line 91: Update the list branch in the `releaseNote.intro` condition to use
`releaseNote.stats` for its link when stats are available, so summaries without
intro prose still show change and contributor counts; retain the existing GitHub
link fallback when stats are absent.

Review comments at @scripts/generate-release-notes.ts:
- Around line 288-293: Validate `response.status` before accepting text in the
response extraction flow: only return the summary when the status is
`"completed"`; return `Option.none` for incomplete responses so the workflow
uses its fallback and leaves the output file absent.
