 # Änderungsprotokoll
 
+## 1.0.9 – 2026-09-24
+
+### Behoben
+
+- Beim Start einer Synchronisation wird die Fortschrittsanzeige sofort zurückgesetzt. Bereits beim Einlesen von Quelle und Ziel erscheinen der aktuelle Ordner und die Anzahl gefundener Dateien; eine vorherige Updateanzeige bleibt nicht mehr unverändert stehen.
+- Der Gesamtstatus kennzeichnet einen laufenden Vorgang eindeutig mit „Synchronisierung läuft“.
+- Windows-Verzeichnisverknüpfungen (Junctions) werden beim Einlesen übersprungen, damit insbesondere AppData nicht mehrfach oder zyklisch durchsucht wird.
+- Bei einer Unterauswahl werden nicht ausgewählte Verzeichniszweige nicht mehr vollständig durchsucht.
+
+## 1.0.8 – 2026-09-24
+
+### Behoben
+
+- Der Updatewächter wartet zusätzlich zu den auslösenden PyInstaller-Prozessen auf weitere Instanzen derselben installierten Anwendung. Solange diese noch laufen, wird der Installer nicht gestartet.
+- Das tatsächliche Ende des Installers und sein Exitcode werden zuverlässig erfasst. Der Wächter wartet dabei nicht auf die anschließend neu gestartete Anwendung.
+- Abgebrochene Installationen und weiterhin laufende Instanzen werden protokolliert und beim nächsten Programmstart mit der tatsächlich gestarteten Version angezeigt.
+- Installations- und Protokollpfade mit Leerzeichen oder Apostrophen werden beim Aufruf des Installers korrekt übergeben.
+
 ## 1.0.7 – 2026-09-24
