 # Änderungsprotokoll

+## 1.0.7 – 2026-09-24
+
+### Behoben
+
+- Bei gesperrten Dateien, etwa in AppData, zeigt SyncVito eine kompakte Zusammenfassung und kennzeichnet die Sicherung als unvollständig. Vollständige Dateipfade und bekannte Sperrprozesse erscheinen im Protokoll.
+- Fehlende Zugriffsrechte werden von tatsächlichen Dateisperren unterschieden; zusätzliche Fehler bleiben auch bei teilweise blockierten Sicherungen sichtbar.
+- Die Sperrerkennung berücksichtigt die tatsächlich betroffene Quell- oder Zieldatei und verarbeitet Windows-Dateihandles und Fehlercodes korrekt.
+- Automatische Wiederholungsversuche starten bereits nach Freigabe einzelner Dateien und berücksichtigen alle bereitstehenden Aufgaben.
+- Während eines erneuten Synchronisationslaufs bleibt dessen Aktivität im Gesamtstatus sichtbar.
+
+## 1.0.6 – 2026-09-24
+
+### Behoben
+
+- Dateianzeige und Fortschrittsleiste besitzen nun feste Breiten und verschieben sich beim Wechsel zwischen unterschiedlich langen Dateipfaden nicht mehr.
+- Lange Dateipfade werden platzsparend gekürzt; der vollständige Text bleibt als Tooltip verfügbar.
+
+## 1.0.5 – 2026-09-24
+
+### Neu
+
+- SyncVito prüft bei jedem Programmstart und während des Betriebs alle 30 Minuten automatisch auf Updates.
+- Verfügbare Updates werden zusätzlich zum Hinweisfenster mit einer auffälligen „UPDATE“-Kennzeichnung am Eintrag „Einstellungen“ angezeigt.
+
+### Behoben
+
+- Wird eine automatische Prüfung durch eine laufende Synchronisation oder Updateaktion verhindert, wird sie nach einer Minute erneut versucht.
+
+## 1.0.3 – 2026-09-24
+
+### Behoben
+
+- Der automatische Neustart nach einem internen Update setzt nun die geerbte PyInstaller-Laufzeitumgebung zurück und verhindert dadurch den Sicherheitsfehler beim Start der aktualisierten Anwendung.
+
+## 1.0.2 – 2026-09-24
+
+### Behoben
+
+- Die Versionsanzeige in der Seitenleiste verwendet nun immer die zentrale Anwendungsversion.
+- Unter der Versionsnummer wird jetzt „by Davito“ statt „Lokale Konfiguration“ angezeigt.
+
 ## 1.0.1 – 2026-09-23
