+## [1.1.103] – 2025-05-19
+
+### Changed
+
+- 🔁 `MapComponent.js` überarbeitet:
+  - `usePoiTypData` entfernt
+  - POI-Typen werden jetzt über Redux (`poiTypesSlice`) geladen
+  - Zustand `isPoiTypLoaded` durch Redux `status === "succeeded"` ersetzt
+- 🔧 Redux-Selektor und `dispatch(fetchPoiTypes())` ergänzt für automatisches Laden
+
+### Fixed
+
+- ✅ Fehler "Cannot access 'isPoiTypLoaded' before initialization" behoben
+- Build funktioniert wieder nach Hook-Löschung
+
+---
+
 ## [1.1.101] – 2025-05-19
 
 ### Removed
