 ## [Unreleased]

+### Fixed
+
+* Make the required single platform destination explicit when creating an installation
+* Fix installation form submission on NetBox v4.6.5 when form mixins return no cleaned-data value
+* Prevent the notification log creation flag from shadowing Django's translation function during email delivery
+* Use NetBox's configured `EMAIL['FROM_EMAIL']` value as the SMTP sender instead of Django's localhost fallback
+* Register the expiration event with a concrete string so NetBox 4.6 can render the notification dropdown
+
 ### Added

 * Optional tenant group and tenant assignments for software licenses
+* German translation for navigation, forms, tables, detail views, choices, and validation messages
+* Optional lifetime or recurring renewal interval for licenses
+* Optional license file, license key, and provider portal URL
+* Daily license expiration notifications for users who subscribe to a license
+* Default reminders one month and one week before expiration plus an optional custom interval
+* Optional SMTP email in addition to mandatory NetBox notifications

 ### Changed

 * Support NetBox v4.6.5
 * Replace the Docker-based setup with Git/Pip installation documentation
+* Render tenant group and tenant in a dedicated license form section
+* Bump the package version so Git/Pip upgrades replace older installations
+* Make the license type field optional
+* Show the plugin under Licences in the main menu
+* Restrict SMTP notification activation to administrators and explicitly authorized users
+* Repeat NetBox and optional email reminders on every daily job run from the first due interval through expiration

 - Installationen Geräten, virtuellen Maschinen oder Clustern zuordnen
 - Softwarelizenzen einschließlich Laufzeit, Umfang und Ablageort verwalten
+- Lifetime-Lizenzen oder Erneuerungsintervalle in Tagen, Monaten oder Jahren erfassen
+- Lizenzdateien, Lizenzschlüssel und Links zum Anbieterportal hinterlegen
+- Ablaufwarnungen standardmäßig einen Monat und eine Woche vor Lizenzende
+- Zusätzliche eigene Vorwarnzeit in Tagen, Wochen oder Monaten
+- NetBox-Benachrichtigungen und optionaler E-Mail-Versand über die NetBox-SMTP-Konfiguration
 - Lizenzen Mandantengruppen und Mandanten zuordnen
 - Bedienung über die NetBox-Oberfläche und REST-API
 - Filter, Bulk-Import und Bulk-Bearbeitung

+> **Hinweis:** Lizenzschlüssel werden in der NetBox-Datenbank und Lizenzdateien im konfigurierten NetBox-

 ```

+Die installierte Version kann anschließend geprüft werden:
+
+```bash
+/opt/netbox/venv/bin/pip show netbox-slm
+```
+
+Für diese Variante muss dort mindestens Version `1.12.0` stehen.
+
+## Ablaufbenachrichtigungen
+
+Für Lizenzen mit Ablaufdatum sind Benachrichtigungen standardmäßig aktiviert. Die Standardtermine liegen einen
+Monat und eine Woche vor dem Ablaufdatum. Pro Lizenz kann zusätzlich eine eigene Vorwarnzeit festgelegt oder die
+Standardtermine deaktiviert werden.
+
+Empfänger entscheiden selbst, ob sie informiert werden: Vertrieb, zuständiger Techniker oder andere Benutzer öffnen
+die Lizenz und wählen die NetBox-Aktion **Abonnieren**. Mit **Abonnement beenden** können sie die Meldungen wieder
+abschalten. Ohne Abonnenten wird keine Nachricht versendet.
+
+Die NetBox-Nachricht wird immer erzeugt. Wird an der Lizenz zusätzlich **E-Mail-Benachrichtigungen** aktiviert, sendet
+das Plugin auch eine E-Mail an die im Benutzerkonto hinterlegte Adresse. Dafür muss der SMTP-Versand in NetBox
+konfiguriert sein.
+
+Die Aktivierung des E-Mail-Versands darf nur durch Administratoren oder Benutzer mit der Berechtigung
+`netbox_slm.manage_softwarelicense_email_notifications` geändert werden. Die eigentlichen SMTP-Zugangsdaten werden
+ausschließlich in der NetBox-Serverkonfiguration gepflegt und sind im Plugin nicht einsehbar.
+
+Die Prüfung läuft einmal täglich als NetBox-Systemjob. Sobald der erste konfigurierte Erinnerungstermin erreicht ist,
+werden die Abonnenten bei jedem Joblauf erneut informiert: immer über NetBox und bei aktivierter E-Mail-Option
+zusätzlich per SMTP. Dies wird bis einschließlich des Ablaufdatums wiederholt. Der NetBox-RQ-Worker muss dafür mit
+Scheduler-Unterstützung laufen; dies ist bei der regulären NetBox-Installation mit `rqworker` standardmäßig der Fall.
