+    *   **[MAJOR] v0.9.0: Role Matching Optimization & Portability (March 2026)**
+        *   **Pattern Optimizer:** Asynchrones Hintergrund-System zur automatischen Konsolidierung von Einzel-Matches in mächtige Regex-Regeln via Gemini. Inklusive Konfliktprüfung gegen andere Rollen. Nutzt `ast.literal_eval` für robustes Regex-Parsing.
+        *   **Database Management:** Direkter Up- & Download der SQLite-Datenbank aus dem UI heraus. Automatisches Backup-System bei Upload.
+        *   **Regex Sandbox:** Integriertes Test-Tool für Muster vor der Speicherung in der Datenbank.
+        *   **Smart Suggestions:** Live-Analyse der Kontaktdaten zur Identifikation häufiger Schlüsselwörter pro Rolle als Klick-Vorschläge.
     *   **[CRITICAL] v0.7.4: Service Restoration & Logic Fix (Jan 24, 2026)**
     *   **[STABILITY] v0.7.3: Hardening Metric Parser & Regression Testing (Jan 23, 2026)**
     *   **[STABILITY] v0.7.2: Robust Metric Parsing (Jan 23, 2026)**
