+# Release Notes v2.2.40
+
+Dato: 3. marts 2026
+
+## Hotfix: Production build source override
+- Rettet Docker build-flow i `Dockerfile`, så release-kode hentet via `RELEASE_VERSION` ikke bliver overskrevet af lokal checkout under image build.
+- Dette løser scenarier hvor produktion kører forkert kodeversion (fx manglende routes som `/dashboard/mission-control`) selv når korrekt release-tag er angivet.
+
+## Tekniske ændringer
+- Lokal kildekode kopieres nu til midlertidig mappe (`/app_local`).
+- Ved release-build (`RELEASE_VERSION != latest` og token sat) bevares downloadet release-kilde i `/app`.
+- Ved local/latest-build kopieres `/app_local` til `/app` som før.
+
+## Verificering
+- Build output skal vise:
+  - `Downloading release ... from Gitea...`
+  - `Keeping downloaded release source in /app (no local override)`
+- Efter deploy skal `/dashboard/mission-control` ikke længere returnere 404 på release v2.2.39+.
