Problem

On the Stable update channel, when the offered stable release is not on the first page of the GitHub releases Atom feed, the desktop update button shows the newest Nightly's notes under the stable version. electron-updater 6.8.9's GitHub provider falls back to the feed's first entry when it cannot find the /releases/latest tag, and with fullChangelog off it returns that entry's note as an untagged string, which T3 then attributes to the offered version. On today's feed (/releases/latest is v0.1.7, all 10 feed entries are 0.1.8-nightly.*), an update from 0.1.6 offers 0.1.7 with the "5 bug fixes" summary of 0.1.8-nightly.20261107.4340.

Change

• The desktop updater requests the full changelog on every channel, not only Nightly. electron-updater then tags each note with its release's version, and the existing channel filter in normalizeDesktopUpdateReleaseNotes drops the Nightly entries, so a stable release missing from the feed shows no notes instead of a Nightly's.
• The same filter now also drops preview builds. They read as Stable to desktopUpdateChannelOf, are never offered as updates, and their feed note is a "do not install" warning; with the full changelog on, a preview cut inside a Stable update range would otherwise appear as a note group.
• Like Nightly already does, Stable now lists notes for skipped stable releases between the running and offered versions (up to six groups). A guarded Nightly→Stable track switch to an older stable release shows no notes, since no release is newer than the running build.

Scope and approval

Fixes #32827

Triaged via the automated issue flow.

Verification

• vp test run apps/desktop/src/updates at 418043f16e (main f12bb6229c merged): 5 files, 92 tests pass. Run against main's production modules, the changed tests fail exactly twice: the missing-Stable attribution and the preview leak.
• Red on main (7b680b616f), green on this branch:
  • DesktopUpdates.test.ts › "shows no notes for a Stable release missing from the releases feed" fails on main with Stable release shows a Nightly's notes: expected [ { version: '1.2.4', … } ] to deeply equal []. It feeds electron-updater's real computeReleaseNotes a synthetic Atom feed with the fullChangelog value the service configured.
  • releaseNotes.test.ts › "keeps only stable releases on the latest channel" (now with a preview entry) fails on main with the preview version kept.
  • "shows a Stable release's own notes from the releases feed" passes on both, guarding that a present stable release keeps its notes.
• vp run check:changed: format, lint, knip, typecheck, tests pass.
• Two independent reviews of 418043f16e found no bugs (both MERGE); one reran the provider transcript and the red-on-main test swap independently. The proof audit at 418043f16e found the transcript and tests sufficient with an empty capture set (fixture matrix): empty notes fall back to the update button's existing tooltip, the popover already renders multiple note groups for Nightly, and no renderer code changes.
• Runtime transcript: electron-updater 6.8.9's real GitHubProvider.getLatestVersion with T3's Stable settings (/releases/latest → v0.1.7, the real latest-linux.yml from v0.1.7, the live releases feed recorded 2026-11-08, plus synthetic feeds), then T3's normalizeDesktopUpdateReleaseNotes. This is a desktop main-process change with no render-path change, so there are no captures; the popover renders whatever notes this produces.

Walkthrough

Desktop update processing now filters release notes against the offered version when a release name is available, before normalizing them. Tests cover Stable updates when the Stable release is missing from or present in the feed, including a switch from Nightly.

Layer / File(s)	Summary
Offered-version release-note selection apps/desktop/src/updates/releaseNotes.ts, apps/desktop/src/updates/DesktopUpdates.ts, apps/desktop/src/updates/DesktopUpdates.test.ts	The updater selects string release notes whose release name matches the offered version before normalization. UpdateInfo accepts an optional nullable releaseName. Tests cover Stable updates with a missing or present Stable feed entry, including switching down from Nightly.

Explanation

Issue #32827 requires notes for the offered Stable release, or no notes when the provider returns another release's notes. releaseNotesOfOfferedVersion in releaseNotes.ts rejects untagged string notes when releaseName does not identify the offered version. Tagged notes continue through the channel filter, which drops Nightly entries for Stable. The added DesktopUpdates.test.ts cases cover a missing Stable release, a present Stable release, and a Nightly-to-Stable switch.

Full details: Out of Scope Changes check

Explanation

All changes support issue #32827. releaseName is decoded in DesktopUpdates.ts so the new guard can distinguish provider fallback notes from notes for the offered version. The helper and regression tests are limited to release-note attribution. No unrelated changes appear in the whole-PR diff.

[GPT-6.1 Sol][Codex] on behalf of shivam.

Handing off #32827 to this PR. On corex Linux, a regression test against the real installed electron-updater@6.8.9 GitHub provider, with deterministic HTTP responses, reproduced stable v0.1.7 receiving the first nightly entry's name and Nightly-only feature notes when the stable tag was absent from Atom. This was a provider test, not a desktop UI reproduction. No desktop app or other device was launched, and there are no screenshots or recordings.

The test failed before our local dependency patch on base e11c2fdca7d1e67b0a9ada3bdbd87314efa78557:

expected: tag=v0.1.7, version=0.1.7, releaseName=undefined, releaseNotes=undefined
received: tag=v0.1.7, version=0.1.7,
          releaseName="T3 Code v0.1.8-nightly.20261107.4314",
          releaseNotes="Nightly-only feature"
1 failed, 3 passed

After the local patch at ad0fd1b62db2c5a5aacb1f7dbf6ecc6e2ecd53f9, the provider cases, DesktopUpdates.test.ts, and releaseNotes.test.ts passed: 3 files, 58 tests. The four provider cases cover absent stable, present stable, explicit manifest metadata, and nightly selection. These results cover our unpushed patch, not this PR's head.

Source checks also confirmed all four 0.1.7 platform manifests omit release names and notes, and published updater 6.8.11/6.8.12 retain the fallback. A baseline Linux AppImage built successfully from the base source with compiled version 0.1.6, but integrated desktop verification had not started when you took over. No branch was pushed and no competing PR was opened.

Dismissed: unsolicited automated review from a blocked account.

Evidence

Environment for every capture: Linux x64, Electron 44.10.1 under headless-desktop, app 0.1.8, 1200×850, dark theme, Stable, fresh isolated state. Each commit ran its own built desktop app, server, and client assets. The real GitHub updater provider read deterministic synthetic HTTP responses.

Steps on both commits:

1. Open Settings → About with Stable selected.
2. Click Check for Updates. Offer 0.1.9 with no manifest notes, while the Atom feed contains a newer Nightly and omits 0.1.9.
3. Close Settings and hover the sidebar update button.
4. Repeat on fresh state with 0.1.9 present in the Atom feed as the control.

Not shown:

• Live GitHub pagination and distributed installer behavior were not exercised; the missing-feed-entry condition was supplied deterministically through a local synthetic GitHub endpoint.
• Nightly-to-Stable downgrades, preview updates, and manifest-supplied notes were not exercised; these captures cover the requested Stable-update reproduction and stable-present control.
• macOS and Windows were not exercised; the visual proof uses Linux Electron.
