Springen, Drehen des Geräts, Kapitelwechsel und die Rückkehr zum Lesen bewahren deine Position zuverlässiger. Große Kapitel laden sicher, die Wiedergabe startet schneller und Reader scrollt zu einem Fokus außerhalb des sichtbaren Bereichs.</string>
+    <string name="release_upcoming_imports">Zuverlässigere Importe von EPUB, PDF, MOBI, DOCX und Text: besseres Unicode und Wortzählung für Chinesisch, Japanisch und Koreanisch, ausgelassener gelöschter DOCX-Text, sicherer Umgang mit großen Dateien und Covern sowie zuverlässigeres Abbrechen. Unvollständige EPUBs werden abgelehnt statt als defekte Bücher hinzugefügt.</string>
+    <string name="release_upcoming_search_focus">Die Textstellensuche zeigt Ergebnisse bereits während der Suche. Der Fokusmodus erlaubt Medien und gibt „Nicht stören“ frei, wenn Kairo in den Hintergrund wechselt. Beim Entfernen von Büchern werden ihre Zwischenspeicher aktualisiert.</string>

Passende Bedienelemente werden hervorgehoben.\n\nExportiere gespeicherte Notizen über die Android-Dateiauswahl als PDF oder Markdown, mit lokalisierten Bedienelementen und Dokumenten.\n\nÜberarbeitete Bibliothek und Einstellungen, bessere Bedienung im Querformat und auf kleinen Bildschirmen sowie einheitliche RSVP-Einstellungen in den Leseansichten.\n\nStabilere eingebettete Bilder, Wiederherstellung der Leseposition, HTML-Zeilenumbrüche, Erfassung kurzer Lesesitzungen und App-Updates. Verbesserte Android-Kompatibilität und Barrierefreiheit.</string>
+    <string name="release_120">Gespeichert vereint Lesezeichen, Hervorhebungen und bearbeitbare Notizen.

Reader und zeitgesteuertes Lesen zeichnen Sitzungen auf.\n\nÖffne die originalen EPUB-Inhaltsverzeichnisse und folge ihren Kapitellinks. Verbesserte Navigationsreparatur, präzise Absatzauswahl, Datenintegrität und Barrierefreiheit.</string>
+    <string name="release_110">Importiere PDFs mit auswählbarem Text, FB2, DOCX und weitere Textformate. Der Dateiinhalt hilft bei der Formaterkennung, unterstützte Formate sind in der Bibliothek klarer ersichtlich und große PDFs werden schneller importiert.\n\nPrüfe über Google Play auf Updates und installiere sie. Verbesserte Importprüfung, Android-Kompatibilität und Standardtextgröße für RSVP.</string>
+    <string name="release_108">Zeitgesteuertes Bionic-Lesen ergänzt RSVP mit eigenen Einstellungen, adaptiver Textdarstellung und einer Lesemodus-Auswahl.\n\nImportiere eingefügten Text und Markdown oder teile Text aus anderen Apps mit Kairo.\n\nRSVP erhält fortlaufenden Kontext und kontextbezogene Wiederholung, mit besserer Wortgruppenausrichtung, Zeichensetzungsdauer, Ladeverhalten und Übersetzungen.</string>

 Do not add new features on a release branch.
 
+### In-app changelog and feature tour
+
+Settings → What’s new contains the offline changelog and a replayable feature
+tour. Maintain its content in
+`app/src/main/java/com/kairo/reader/ui/updates/ReleaseNotes.kt` and the
+`values*/release_notes.xml` resources for every supported language.
+
+During development, keep the newest entry's `version` and `versionCode` null.
+It appears as Upcoming and can be toured manually, but never prompts users.
+During release preparation, assign the actual `versionName` and `versionCode`
+from `app/build.gradle.kts` to that entry. Keep older entries in descending order.
+When starting the next version, prepend a new Upcoming entry. A fixes-only
+release may leave its tour empty and offer just the changelog.
+
+Review `git log --no-merges <previous-release-tag>..HEAD` and the corresponding
+diffs. Summarise every user-facing addition and fix in the changelog, grouping
+related commits; omit internal build, test, and refactoring work. Pick only a few
+features for the tour. Keep its steps on Library or Settings so it works without
+an imported book. New targets must also register their highlight bounds and
+scroll requesters on those screens. The app uses packaged notes, not Git or a
+network service at runtime.
+
+The initial history covers `v1.0.7..v1.0.8`, `v1.0.8..v1.1.0`,
+`v1.1.0..v1.2.0`, and `v1.2.0..v1.3.0`. The first Upcoming entry covers
+`v1.3.0..2785d82` plus the new changelog and tour itself.
+
+Before shipping, run `./gradlew qualityGate :app:compileDebugAndroidTestKotlin`
+and the `WhatsNewDeviceTest` instrumentation tests on a device. Check an upgrade
+from the previous published version: the invitation appears once in an idle
+library, all dismissal paths suppress it, and Settings can replay the tour.
+Check a fresh install too: only the starting tutorial should appear. Verify
+rotation, Back, large text, landscape, and pending external imports. Resetting
+display preferences must not reset the acknowledged release version.
+
 When the release is ready:
 
 ```bash
