+## [0.10.0] - 2026-07-02
+
+### Added
+- Docker-Setup: `Dockerfile` (PHP 8.5 FPM + nginx + Node.js 20 + nmap + supervisor), `docker-compose.yml` (App + MariaDB 11), automatischer Startup via `entrypoint.sh` (wartet auf DB, migriert, baut Assets, startet Supervisor)
+- `docker/nginx.conf`, `docker/supervisord.conf`: nginx als Reverse-Proxy zu PHP-FPM, Laravel Scheduler als Supervisor-Job
+- `.dockerignore` für minimale Image-Größe
+- `.env.example` auf Docker-Betrieb angepasst (DB_HOST=db, MariaDB-Variablen, APP_PORT)
+- Software-Update-Funktion: Admin → Einstellungen → 🔄 Software-Update
+- `config/version.php`: zentrale Versionsverwaltung, konfigurierbare Gitea-URL
+- Artisan-Command `app:check-update`: prüft Gitea-API auf neuere Release-Tags, speichert Ergebnis 6 Stunden im Cache
+- Artisan-Command `app:install-update`: führt `git fetch`, `git checkout <tag>`, `composer install`, `npm run build`, `php artisan migrate`, Cache-Rebuild durch — mit automatischem Wartungsmodus
+- `UpdateController` (Admin): Update-Seite mit Versionsvergleich, Release-Notes, Install-Button, manueller Tag-Eingabe
+- Navigation: „Update"-Badge im Einstellungen-Dropdown wenn neue Version verfügbar (liest aus Cache, kein Live-HTTP-Request)
+- Update-Check alle 6 Stunden via Laravel Scheduler (`app:check-update`)
+- Wartungsseite `errors/maintenance.blade.php` mit Auto-Reload
+
+### Setup (einmalig)
+```
+GITEA_URL=http://<IP-des-Gitea-Servers>:3000
+GITEA_REPO=admin/Network-MGMT
+```
+In `.env` eintragen, danach steht der Update-Check zur Verfügung.
+
+### Docker-Deployment
+```bash
+git clone http://<gitea>:3000/admin/Network-MGMT.git
+cd Network-MGMT
+cp .env.example .env
+# .env anpassen (Passwörter, APP_URL, GITEA_URL)
+docker compose up -d --build
+```
+
+---
+
+## [0.9.0] - 2026-07-02
+
+### Added
+- Geräte-Tracking ohne MAC-Adresse: nmap-Hosts aus Remote-Subnetzen (kein ARP möglich) werden jetzt als `network_devices`-Einträge erfasst (Tracking per Hostname, Fallback per IP)
+- `mac_address` in `network_devices` ist jetzt nullable (mehrere NULL-Werte durch MySQL erlaubt)
+- Dashboard: Separater Warnblock „⚠️ IP-Adressen-Wechsel erkannt" mit Anzeige alter IP → neuer IP, Gerätename, MAC, Quittier-Button inkl. Notizfeld
+- Alle anderen Ereignisse auf dem Dashboard ebenfalls mit inline Notiz quittierbar
+- Geräte-Detailseite: IP-Verlauf zeigt Hinweis wenn ein Gerät mehrere verschiedene IPs hatte, alle bekannten IPs als Tags, aktuelle IP hervorgehoben
+- Globale Suche: `netbios_name` wird jetzt mitdurchsucht
+- Globale Suche: Zeigt auch Treffer direkt aus `network_hosts` (Scan-Verlauf) wenn noch kein Geräteeintrag vorhanden
+- Artisan-Command `network:backfill-devices`: Erstellt `network_devices`-Einträge für alle bestehenden `network_hosts` ohne `device_id`
+
+### Setup (einmalig)
+```
+php artisan migrate
+php artisan network:backfill-devices
+```
+
+---
+
+## [0.8.0] - 2026-07-02
+
+### Added
+- IP-Bemerkungen: Pro IP-Adresse je Segment eine Bemerkung hinterlegen (inline editierbar in der Scan-Detailansicht)
+- Neue Tabelle `network_ip_notes` (Segment + IP als Unique-Key)
+- Subnetz-Erkennung: Schaltfläche „🔍 Erkennen" in Segment anlegen/bearbeiten – ermittelt /24-Subnetze aus vorhandenen IP-Daten per API (`/network/detect-subnets`)
+- Export Segment als Excel (`.xlsx`) via PhpSpreadsheet – enthält alle Hosts des letzten Scans inkl. Bemerkungen
+- Export Segment als PDF via DomPDF – Querformat-Tabelle mit Hosts, Status, MAC, Hostname, Hersteller, Ping und Bemerkungen
+- Export-Buttons (📊 Excel / 📄 PDF) auf Segment-Detailseite und Scan-Detailseite
+
+### Setup (einmalig ausführen)
+```
+composer require phpoffice/phpspreadsheet barryvdh/laravel-dompdf
+php artisan migrate
+```
+
+---
+
+## [0.7.0] - 2026-07-02
+
+### Added
+- Automatischer Netzwerkscan via `nmap` pro Segment (Artisan Command `network:scan`)
+- Scan-Zyklus pro Segment einstellbar: 5 / 15 / 30 / 60 / 360 / 720 / 1440 Minuten
+- „Jetzt scannen"-Button direkt auf der Segment-Detailseite
+- nmap-Parameter pro Segment konfigurierbar (z.B. `-sn`, `-sn -p 22,80,443`)
+- Laravel Scheduler führt `network:scan` jede Minute aus und prüft fällige Segmente
+- Auto-Refresh auf Segment-Detailseite nach manuellem Scan (prüft alle 10s)
+- Chronologischer IP-Verlauf (`/network/history`) über alle Scans und Segmente
+- Filter im IP-Verlauf: IP, MAC, Hostname, Segment, Status, Datumsbereich
+- IP-Verlauf Auto-Refresh alle 60 Sekunden (ohne aktiven Filter)
+- Navigation: neuer Menüpunkt „IP-Verlauf"
+- `last_scanned_at` und `scan_interval_minutes` in Segment-Stammdaten
+
+### Setup (Cron für Scheduler)
+```
+* * * * * cd /home/arudolph/Projekte/PHP/Network-MGMT && php artisan schedule:run >> /dev/null 2>&1
+```
+
+---
+
+## [0.6.0] - 2026-07-01
+
+### Added
+- Netzwerk-Segmentverwaltung: Subnetze mit Name, VLAN-ID und Aktiv/Inaktiv-Flag definieren
+- Neue Tabelle `network_segments` als organisatorische Einheit für Scan-Durchläufe
+- Dashboard-Ansicht „Netzwerk" mit Übersicht aller Segmente, KPI-Karten und offenen Ereignissen
+- Globale Suche über alle Segmente nach IP, MAC, Hostname und Bezeichnung
+- Navigation „Netzwerk" als Dropdown: Dashboard, Segmente, Alle Geräte, Suche, Import
+- Import-Seite: Segment-Auswahl beim Upload eines Angry IP Scanner Exports
+- Segment-Detailseite mit Scan-Historie
+- `segment_id` FK in `network_scans` Tabelle
