+📝 Notes de version - Scan-Wich
+
+**Nouveautés de la version actuelle :**
+
+☁️ **Synchronisation Cloud Totale (Zéro Re-saisie) :**
+- **Mémoire Cloud :** Votre profil (poids, objectifs, calories cibles) est désormais entièrement sauvegardé dans le Cloud. Plus besoin de retaper vos informations lors d'une mise à jour ou d'une réinstallation !
+- **Rapatriement Automatique :** L'application récupère instantanément tout votre historique (repas, sport, glycémie) et vos paramètres dès la connexion.
+- **Modèles de données optimisés :** Mise à jour des structures internes pour garantir une compatibilité parfaite avec Firebase lors de la récupération des données.
+- **Résilience Keystore :** Ajout d'un système d'auto-réparation en cas de corruption des clés de sécurité locales, évitant ainsi les fermetures inattendues de l'application.
+
+🍲 **Focus Nourriture Pur (IA) :**
+- **Analyse sélective :** L'intelligence artificielle se concentre désormais exclusivement sur la nourriture. Les qualificatifs, les descriptions de l'environnement ou les éléments de décor sont ignorés pour ne garder que l'essentiel nutritionnel.
+
+🔔 **Rappels de Repas :**
+- **Notifications intelligentes :** Ne manquez plus un enregistrement ! Des rappels automatiques ont été ajoutés pour le déjeuner (08h30), le dîner (12h30) et le souper (19h30).
+
+---
+
+**Changements majeurs précédents :**
+
+🇫🇷 **Expérience 100% en Français :**
+- **IA Francophone :** Les analyses de repas (caméra et manuel) sont désormais exclusivement en français.
+- **Scanner Localisé :** Utilisation de la base de données française d'Open Food Facts.
+
+🤖 **Analyse IA plus Robuste :**
+- **Fiabilité accrue :** Nettoyage automatique des données nutritionnelles côté serveur.
+
+🚀 **Connexion Strava 100% Automatique :**
+- **Simplicité totale :** Connexion en un seul clic sans saisie d'identifiants techniques.
+
+🛡️ **Architecture Cloud & Sécurité :**
+- **Gestion des accès :** Contrôle dynamique des utilisateurs autorisés via Firestore.
+- **Secret Manager :** Protection maximale des clés API via Google Cloud.
+
+---
+
+🛠️ **Historique technique :**
+- Export PDF Professionnel (Repas, sport, glycémie).
+- Suivi Diabétique complet.
+- Intégration Firebase App Check (Play Integrity).
+- Algorithme d'estimation MET pour le sport.
+- Optimisation pour Android 36.
