+## [0.18.2] — 2026-09-08
+
+Patch release on top of v0.18.1. The `[0.18.1]` section of `CHANGELOG.md`
+listed only #96 (suite-drift gate) and #97 (docs half-sentence), but missed
+the two issues that produced the `check-changelog` gate itself — #92
+(OPEN-120, Keep-a-Changelog section reordering) and #93 (OPEN-121, the
+`scripts/check-changelog.mjs` script and its `test/changelog.mjs` suite).
+The gate was already sound on the file; only the human-maintained bullet
+text was incomplete. This release closes the loop on the `0.18.1` historical
+record. No user-visible change, no API or schema drift; the CI guards
+introduced in `0.18.1` continue to apply.
+
+### Fixed
+
+- `CHANGELOG.md` `[0.18.1]` block now lists #92 and #93 alongside #96 and
+  #97, and the section intro is pluralised so the prose matches the two
+  guards. Completeness of the human-maintained prose is the change; the
+  `check-changelog` script itself was untouched
+  ([#100](https://github.com/m-dohmen/openToolbox/pull/100)).
