+# 🎉 AniTrack v0.7.0 Release Notes
+
+## 🚨 Major Feature: Comprehensive Error Handling
+
+This release brings **massive improvements** to application stability and user experience. The app will **no longer crash** when API services are down or experiencing errors!
+
+---
+
+## ✨ What's New
+
+### 🛡️ Graceful API Error Handling
+- **Application Stability**: App now remains running even when AniList, MAL, or Simkl APIs are down
+- **Visual Error Feedback**: Beautiful modal dialogs display error details instead of silent crashes
+- **Manual Retry**: Users can retry failed API connections with a single button click
+- **Continue Using App**: Dismiss error messages and continue with limited functionality
+
+### 🔧 Backend Improvements
+
+#### AniList Integration
+- Replaced all `log.Fatal()` calls with proper error returns
+- Added error handling for API failures, network issues, and authentication errors
+- `AniListSearch` now returns detailed error messages
+- `GetAniListUserWatchingList` gracefully handles 403/404 responses
+
+#### MyAnimeList Integration
+- Updated `MALHelper` to return structured errors
+- All MAL API functions now return errors instead of crashing:
+  - `GetMyAnimeList`
+  - `MyAnimeListUpdate`
+  - `GetMyAnimeListAnime`
+  - `DeleteMyAnimeListEntry`
+- Fixed OAuth callback server to prevent shutdown on errors
+
+#### Simkl Integration
+- Updated `SimklHelper` with status code validation (200-299 range)
+- All Simkl API functions now return errors:
+  - `SimklGetUserWatchlist`
+  - `SimklSyncEpisodes`
+  - `SimklSyncRating`
+  - `SimklSyncStatus`
+  - `SimklSearch`
+  - `SimklSyncRemove`
+- Replaced `log.Fatal()` with proper error logging
+
+### 💻 Frontend Improvements
+
+#### New Error Management System
+- **Centralized Error State**: New reactive stores for API errors
+  - `apiError` - Tracks current error with service, message, and status
+  - `isApiDown` - Quick flag for API availability
+- **Error Helper Functions**:
+  - `setApiError()` - Set error state from any component
+  - `clearApiError()` - Reset error state
+
+#### New Error Modal Component
+- Auto-displays when API errors occur
+- Shows service name, error message, and HTTP status code
+- **"Retry Connection"** button - Attempts to reconnect to the failed service
+- **"Dismiss"** button - Close modal and continue using the app
+- Beautiful red-themed styling with Tailwind CSS
+- Supports all three services (AniList, MAL, Simkl)
+
+#### Updated User Interface
+- Home page now displays "API Unavailable" state when services are down
+- Helpful warning messages guide users during outages
+- App structure remains visible and functional during errors
+
+---
+
+## 🐛 Bug Fixes
+
+- **Critical**: Fixed app crashes when AniList API returns 403 Forbidden errors
+- **Critical**: Fixed app crashes when AniList API is down or unreachable
+- **Critical**: Fixed MAL OAuth server crashing on connection errors
+- **Critical**: Fixed Simkl JSON marshaling errors crashing the app
+- **Improved**: Better error messages for all API failures
+
+---
+
+## 📊 Technical Details
+
+### Go Backend Changes
+- **AniListFunctions.go**: Updated 3 functions with error handling
+- **MALFunctions.go**: Updated 5 functions with error handling
+- **MALUserFunctions.go**: Fixed server error handling
+- **SimklFunctions.go**: Updated 7 functions with error handling
+- **SimklUserFunctions.go**: Fixed 2 critical error handling issues
+
+### Frontend Changes
+- **ErrorModal.svelte**: New component (73 lines)
+- **GlobalVariablesAndHelperFunctions.svelte**: Added error state system (27 lines)
+- **App.svelte**: Integrated ErrorModal into main layout
+- **CheckIfAniListLoggedInAndLoadWatchList.svelte**: Added error handling
+- **Home.svelte**: Added API down state display
+
+---
+
+## 🎯 Impact
+
+### Before (v0.6.5)
+- ❌ App crashes to desktop when AniList API is down
+- ❌ Users see only console error messages
+- ❌ Must restart app after API failures
+- ❌ No way to retry failed connections
+
+### After (v0.7.0)
+- ✅ App stays open during any API failures
+- ✅ Beautiful modal dialogs explain what went wrong
+- ✅ One-click retry to reconnect services
+- ✅ Continue using app with limited functionality
+
+---
+
+## 🔄 Upgrading
+
+No migration needed! This release is fully backward compatible.
+
+Simply run:
+```bash
+git pull
+wails build
+```
+
+Or download the latest release from the releases page.
+
+---
+
+## 🙏 Acknowledgments
