Problem

The GitHub Releases for v1.5.0 and v1.6.0 have an empty body — no patch notes.

Both tags were cut from the GitHub "Draft a new release" UI, which publishes the release before the tag push reaches release.yml:

tag release author release created workflow start body
v1.4.2 github-actions[bot] 14:47:52 14:51:49 ✅ notes
v1.5.0 Turbootzz 13:42:46 13:44:13 ❌ empty
v1.6.0 Turbootzz 14:58:59 14:59:49 ❌ empty

The re-run guard added in #76 only asked does the release exist?. It found one, set new=false, disabled generate_release_notes — so the workflow attached the binaries to an empty body and moved on.

Fix

The guard existed because the action's generate_release_notes appends to an existing body on a re-run (softprops/action-gh-release#827), so the workflow had to guess whether notes were already there. Every version of that guess has failure modes: an existence check misses the UI-created release, a body check flips to duplicate-generate on a transient gh error and treats a whitespace-only body as "has notes".

So don't guess. Call the generate-notes API directly and pass the result as body_path:

- name: Generate release notes
  env:
    GH_TOKEN: ${{ github.token }}
  run: |
    gh api --method POST "repos/${GITHUB_REPOSITORY}/releases/generate-notes" \
      -f tag_name="$GITHUB_REF_NAME" --jq .body > notes.md
    cat notes.md

Same body on every run, regardless of who created the release. The guard step is gone.

Trade-off, now documented: the job owns the title and body, so a description typed by hand is overwritten if the job re-runs. RELEASE.md says to push the tag from the CLI, and carries the recipe for regenerating against a different baseline (the prerelease-baseline caveat).

Verified against the live API — the .github/release.yml filter still applies (the release-plz bump PR is excluded from the generated list).

Notes

  • CI-only change; no Rust code touched.
  • tests/http_client.rs::an_empty_root_store_is_reported_with_the_fix fails locally on macOS (pre-existing on main, unrelated): rustls-native-certs reads the Security-framework keychain there and ignores SSL_CERT_FILE/SSL_CERT_DIR, so the root store is never empty. Green on Linux CI.
  • The empty bodies on v1.5.0 / v1.6.0 are backfilled separately with the same API — this fix only stops it recurring.

🤖 Generated with Claude Code

v1.5.0 and v1.6.0 shipped with an empty body. Both tags were cut from the
GitHub "Draft a new release" UI, which publishes the release before the tag
push reaches the workflow. The re-run guard added in #76 only asked whether the
release existed, so it saw one and skipped note generation.

Key the guard off the body instead: a re-run still keeps its notes (the append
bug, softprops/action-gh-release#827), while a UI-created release with an empty
body now gets them. RELEASE.md says to push the tag from the CLI.

📝 Walkthrough

Walkthrough

The release workflow now checks whether the release body is empty before generating notes. The manual release instructions now require maintainers to push tags from the CLI.

Changes

Release note handling

Layer / File(s) Summary
Release note detection and manual release process
.github/workflows/release.yml, RELEASE.md
The workflow retrieves the release body and treats an empty body as requiring generated notes. The manual process instructs maintainers to push the tag from the CLI.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 94f09

Release lookup failures could cause existing release notes to be rewritten or duplicated, so error handling should be corrected before merge. The release instructions should also accurately distinguish empty from non-empty UI-created releases.

Review follow-up. Keying off the body was still a heuristic on a non-idempotent
input: a transient `gh` error read as "no body" and re-armed the append bug, a
whitespace-only body read as "has notes", and a deliberately blanked body got
repopulated on any re-run.

Call the generate-notes API directly and pass the result as `body_path`, so the
job writes the same body every time regardless of who created the release. Drops
the guard step entirely. RELEASE.md states that the job owns the title and body,
and documents the regenerate-against-another-baseline recipe.
