+# Changelog
+
+## [1.5.0] - 2024-01-07
+
+### 🚀 Nouvelles fonctionnalités
+- **Intégration d'AnimeJS** pour des animations fluides et performantes
+- **Loader animé** au chargement de l'application avec barre de progression
+- **Animations avancées** :
+  - Hero : Entrée progressive des éléments, étoiles filantes, patterns africains animés
+  - Navigation : Transitions fluides, menu mobile amélioré
+  - Prédictions : Calculateur avec animations de sélection et résultats
+  - Globe : Vague planétaire animée avec particules et progression temporelle
+- **Effets visuels** :
+  - Effet parallaxe amélioré sur le ciel étoilé
+  - Hover animations sur les boutons avec effet élastique
+  - Shimmer effect sur la timeline
+  - Pulsation des marqueurs actifs sur le globe
+
+### 🎨 Améliorations design
+- **Mobile-first** : Toutes les animations optimisées pour mobile
+- **Performance** : Animations GPU-accelerated avec transform et opacity
+- **Interactivité** : Feedback visuel immédiat sur toutes les interactions
+- **Accessibilité** : Respect de prefers-reduced-motion
+
+### 🛠️ Technique
+- AnimeJS 3.2.1 intégré
+- Timeline orchestration pour les animations complexes
+- Optimisation des animations Canvas
+- Lazy loading des animations lourdes
+
+## [1.0.0] - 2024-01-07
+
+### Version initiale
+- Application Svelte avec design panafricain/caribéen
+- Calculateur de prédictions pour 7 sites en Guadeloupe
+- Globe interactif avec GeoJSON
+- Support multilingue (FR, EN, HT)
+- Sections : Science, Culture, Dogons, Observatoire
+- Déploiement GitHub Pages
