+
+**Neu:**
+- **Stationskarte**: Interaktive OpenStreetMap-Karte zeigt die geografische Position aller aktiven Chatmember. Enthält Stationsmarker, Antennen-Kegel, Verbindungslinie zur ausgewählten Station, Maidenhead-Raster-Overlay und ein Wegprofil-Diagramm mit Geländehöhen-Analyse (Fresnel-Zonen, Horizonterkennung). Geländedaten aus Copernicus GLO-30, Open-Meteo API oder Offline-DEM-Import. Aircraft-Scatter-Weganalyse integriert. Funktioniert in AppImage und Flatpak ohne externe CDN-Verbindung (lokaler Tile-Proxy, eingebettetes Leaflet.js).
+
+**Geändert:**
+- **Nachrichten-Tabellen-Limit auf 30.000 erhöht**: Chat- und Nachrichtentabellen sind auf 30.000 Einträge begrenzt. Ältere Nachrichten werden automatisch verworfen, was die Performance bei mehrtägigem Contest-Betrieb stabil hält.
+- **Bildschirmgerechte Fenstergröße**: Beim Start wird das Hauptfenster auf den aktuellen Bildschirm angepasst. Wenn KST4Contest zuletzt auf einem größeren Monitor betrieben wurde, wird das Fenster automatisch verkleinert. Das UI-Layout ist kompakter und reaktionsfähiger auf kleineren Bildschirmen.

+
+## Stationskarte (ab v1.41)
+
+Eine interaktive OpenStreetMap-Karte zeigt die geografische Position aller aktiven Chatmember.
+
+**Funktionen:**
+
+- Stationsmarker mit Rufzeichen-Labels, farblich nach Aktivität und Sked-Status
+- **Antennen-Kegel** für die eigene Station
+- **Verbindungslinie** zur aktuell ausgewählten Station
+- **Maidenhead-Raster** (QRA-Locator-Gitter als Overlay)
+- **Wegprofil-Diagramm**: Geländehöhen-Querschnitt zwischen eigener und ausgewählter Station, inklusive Fresnel-Zonen-Analyse und Horizonterkennung
+- Mehrere Terrainquellen: **Copernicus GLO-30** (hochauflösendes DEM), **Open-Meteo API**, synthetischer Fallback und **Offline-DEM-Import** für den Betrieb ohne Internetverbindung
+- Aircraft-Scatter-Weganalyse verknüpft mit den Geländedaten
+
+Die Karte funktioniert in gepackten Umgebungen (AppImage, Flatpak) ohne Zugriff auf externe CDNs: Die Kartenkacheln werden über einen lokalen Tile-Proxy abgerufen, die Leaflet.js-Bibliothek ist in der Anwendung eingebettet.

+## Optimierte Nachrichtenverarbeitung / 30.000-Nachrichten-Limit (ab v1.41)
+
+Die internen Chat- und Nachrichtentabellen sind auf **30.000 Einträge** begrenzt. Ältere Nachrichten werden automatisch verworfen, sobald das Limit erreicht wird. Damit bleiben Speicherverbrauch und Darstellungsperformance auch bei mehrtägigen Contest-Betrieb stabil.

+## Bildschirmgerechte Fenstergröße (ab v1.41)
+
+Beim Programmstart berechnet KST4Contest eine bildschirmgerechte Startgröße für das Hauptfenster:

+- Die gespeicherte Fenstergröße aus der letzten Session wird verwendet – aber **niemals größer als der aktuelle Bildschirm**.
+- Wenn KST4Contest zuletzt auf einem größeren Monitor betrieben wurde, wird das Fenster automatisch auf die aktuelle Anzeige verkleinert.
+- Das UI-Layout ist **kompakter und reaktionsfähiger auf kleineren Bildschirmen**.

+## v1.41
+**Station Map, Performance, Responsive UI**
+
+**New:**
+- **Station Map**: Interactive OpenStreetMap-based map showing the geographic position of all active chat members. Includes station markers, antenna beam cone, connection line to the selected station, Maidenhead grid overlay, and a path profile chart with terrain elevation analysis (Fresnel zones, horizon detection). Terrain data from Copernicus GLO-30, Open-Meteo API, or offline DEM import. Aircraft scatter path analysis integrated. Works in AppImage and Flatpak without external CDN access (local tile proxy, bundled Leaflet.js).
+
+**Changed:**
+- **Message table limit raised to 30,000**: Chat and message tables are capped at 30,000 entries. Older messages are automatically discarded, keeping performance stable during multi-day contest operations.
+- **Screen-aware window sizing**: On startup, the main window is sized to fit the current screen. If KST4Contest was last used on a larger monitor, the window is automatically scaled down. The UI layout is more compact and responsive on smaller screens.

+
+## Station Map (from v1.41)
+
+An interactive OpenStreetMap-based map showing the geographic position of all active chat members.
+
+**Features:**
+
+- Station markers with callsign labels, coloured by activity and sked state
+- Antenna **beam cone** visualisation for the own station
+- **Connection line** to the currently selected station
+- **Maidenhead grid** overlay (QRA locator grid)
+- **Path profile chart**: Terrain elevation cross-section between own station and the selected station, including Fresnel zone analysis and obstruction/horizon detection
+- Multiple terrain data sources: **Copernicus GLO-30** (high-resolution DEM), **Open-Meteo API**, synthetic fallback, and **offline DEM import** for air-gapped use
+- Aircraft scatter path analysis integrated with the terrain data
+
+The map works in packaged environments (AppImage, Flatpak) without internet access to external CDNs: map tiles are fetched via a local tile proxy, and the Leaflet.js library is bundled inside the application.
+
+---
+
+## Optimised Message Handling / 30,000 Message Limit (from v1.41)
+
+The internal chat and message tables are capped at **30,000 entries**. Older messages are automatically discarded when the limit is reached. This keeps memory usage and rendering performance stable during multi-day contest operations.
+
+---
+
+## Screen-Aware Window Sizing (from v1.41)
+
+On startup, KST4Contest calculates a screen-aware size for the main window:
+
+- The stored window size from the previous session is used – but **never larger than the current screen**.
+- If KST4Contest was last used on a larger monitor, the window is automatically scaled down to fit the current display without clipping.
+- The UI layout is more **compact and responsive on smaller screens**, showing the same information in less space.
+
+This prevents unusable oversized windows when switching between machines or monitors.
