+- Renforcement de la sécurité : Intégration de Firebase App Check (Play Integrity) pour protéger l'API contre les utilisations non autorisées et sécuriser les appels vers l'IA.
+- Protection des données sensibles : Migration de la clé API vers Google Cloud Secret Manager, garantissant qu'aucune information confidentielle n'est stockée en dur dans le code.
+- Optimisation majeure de l'analyse : Réduction drastique de la latence réseau grâce à un nouveau moteur de compression d'image (passage de 2.2 Mo à ~150 Ko par scan).
+- Sécurisation de l'IA : Migration de la logique des instructions (prompts) côté serveur (Cloud Functions) pour prévenir les manipulations et garantir des résultats fiables.
+- Amélioration de l'authentification : Liaison directe entre Google Sign-In et Firebase Auth pour une session utilisateur plus robuste et sécurisée.
+- Correction du parsing : Nouveau système de traitement des réponses Cloud Functions pour une meilleure fiabilité de l'affichage des macros.
+- Export PDF de l'historique : nouvelle fonctionnalité permettant d'exporter vos repas, suivis de glycémie et activités sportives sous forme de rapport PDF professionnel.
+- Refonte de l'accès aux favoris : intégration d'un bouton dédié et d'une liste modale pour un écran d'accueil plus clair.
+- Mise à jour système : Optimisation pour Android 36 et amélioration de la stabilité globale.
