# After a PR that added changelog fragment(s) is merged, KAIBOT comments on the PR with a
# link to each fragment. Pending fragments are folded into CHANGELOG.md at release time
# (`make changelog-release`), so this confirms to the contributor that their entry was
# recorded even though CHANGELOG.md did not change in the PR.
