-## v1.41
-**Stationskarte, Performance, Reaktionsfähiges UI**
-
-**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.

 Dieses Fenster kann miniaturisiert werden, wenn es nicht benötigt wird. Zukünftig geplant: Filterung auf Stationen im ausgewählten QTF.

-
-## 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**.
-
-Damit werden unbrauchbare, abgeschnittene Fenster beim Wechsel zwischen Geräten oder Monitoren verhindert.

-## 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.

-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.

-The Flatpak repository provides three channels, all served from the same remote:
-
-| Channel | Content | Built on |
-|---|---|---|
-| `stable` | Current stable version | Every normal release tag |
-| `beta` | Pre-release version | Tags prefixed with `beta-` |
-| `nightly` | Development build (main branch) | Every push to main / daily |

-# Stable (default)

-# Nightly
-flatpak install kst4contest de.x08.KST4Contest//nightly
-```
-
-> **Note:** Flatpak only allows one installed version per App-ID at a time. To switch channels, uninstall the current version first:
-> ```bash
-> flatpak uninstall de.x08.KST4Contest
-> flatpak install kst4contest de.x08.KST4Contest//nightly

-# KST4Contest Website Architecture
-
-## Goals
-
-KST4Contest uses GitHub as the central source for code, documentation and releases.
-
-The website is generated statically with Eleventy (11ty) and deployed to:
-
-https://kst4contest.hamradioonline.de
-
-## Documentation Source
-
-The existing `github_docs/` directory remains the single source of truth for the manual.
-
-It is used for:
-
- GitHub Wiki
- PDF manual generation
- Website manual pages
-
-## Website Source
-
-The `website/` directory contains the Eleventy project.
-
-Manual content must not be duplicated inside `website/`.
-
-Marketing, SEO, news, screenshots and download pages belong into `website/src/`.
-
-## URL Structure
-
- `/`
- `/features/`
- `/download/`
- `/screenshots/`
- `/news/`
- `/manual/`
- `/manual/en/`
- `/manual/de/`
- `/faq/`
-
-## Deployment
-
-The generated static output is deployed to:
-
-`/srv/www/kst4contest/current`
-
-Nginx serves this directory.
-
-## Build Strategy
-
-GitHub Actions will later build the 11ty website and deploy the generated output to the server.

-    <h2>Why KST4Contest exists</h2>
-    <p>
-      Generic chat clients display messages. KST4Contest goes further:
-      it helps operators identify candidates, manage skeds, use AirScout timing,
-      synchronize with loggers and reduce workload during VHF/UHF/SHF contests.
-    </p>
-
-    <h2>Open source and practical</h2>
-    <p>
-      The project is open source and focused on practical contest station workflows.
-      Features are designed around real operating pressure, not theoretical UI concepts.
