+# 🎯 Support for Expo 54 & Dynamic Sizing
+
+## ✨ Major Features
+
+### Dynamic Sizing Support
+- **Auto-sizing**: `width` and `height` props are now optional. Carousel automatically measures container dimensions via layout
+
+### Expo 54 Compatibility
+- Full support for Expo SDK 54
+- Updated dependencies for latest React Native ecosystem
+
+## 💥 Breaking Changes
+
+### Dependencies Update Required
+- **react-native-reanimated**: Upgrade to `^4.1.0` (was `^3.0.0`)
+- **react-native-worklets**: New peer dependency `^0.5.1` required
+- **react-native-gesture-handler**: Minimum version `^2.9.0` (no breaking changes)
+
+### Migration Steps
+1. Upgrade Reanimated: `npm install react-native-reanimated@^4.1.0`
+2. Install Worklets: `npm install react-native-worklets@^0.5.1`
+3. Follow Reanimated 4.0 migration guide for any breaking changes
+
+## 🔧 Technical Improvements
+- Replaced deprecated `runOnJS` with `scheduleOnRN` from react-native-worklets
+- Enhanced test coverage for dynamic sizing scenarios
+- Improved overscroll protection logic
+- Better error handling for edge cases
+
+## 📚 Documentation
+- Updated installation guide with new dependency requirements
+- Added migration guide from v4 to v5
+- Enhanced examples showcasing dynamic sizing capabilities
+
+**Fixes**: #668 - Auto height calculation support
