Added #

Error Handling & Recovery

• ✅ Automatic retry for async operations with configurable retry policies
• ✅ Exponential backoff support for retries
• ✅ Error recovery strategies (fallback, custom, retry)
• ✅ Error boundary UI components (ErrorBoundaryWidget)
• ✅ Better error messages with context
• ✅ User-friendly error message extraction

Performance Optimizations

• ✅ Memoization for computed values (optional, enabled via enableMemoization parameter)
• ✅ Circular dependency detection in computed values
• ✅ Dependency graph optimization
• ✅ Enhanced performance monitoring

State Management Patterns

• ✅ Redux-like reducer pattern (ReduxStore, Reducer, Action)
• ✅ State normalization utilities (RxNormalizedState, NormalizedState)
• ✅ Pagination support (PaginationController, SwiftFuturePagination)
• ✅ Action history tracking in Redux stores

Enhanced Debugging

• ✅ Debug mode with verbose logging (DebugMode)
• ✅ Context-aware logging (DebugLogger)
• ✅ Dependency tracking for debugging
• ✅ Enhanced test helpers with async support

Animation Improvements

• ✅ AnimationController support for better performance (replaces polling)
• ✅ Staggered animations (animateSequence)
• ✅ More animation curves support
• ✅ Backwards compatibility with polling fallback

Persistence Enhancements

• ✅ Data migration support (MigrationConfig, MigrationHelper)
• ✅ Version tracking for persisted data
• ✅ Migration utilities for common scenarios

Testing Utilities

• ✅ Enhanced test helpers (SwiftTestHelpers)
• ✅ Mock reactive state (MockReactiveState)
• ✅ Async operation test helpers
• ✅ Transaction testing support
• ✅ Debug mode for testing

Improved #

• ✅ SwiftFuture now supports retry, error recovery, and better error handling
• ✅ Computed now supports memoization and circular dependency detection
• ✅ SwiftTween now uses AnimationController when vsync is provided
• ✅ SwiftPersisted now supports data migrations
• ✅ Error messages are more descriptive and user-friendly
• ✅ Test helpers are more comprehensive

Documentation #

• ✅ Added ADVANCED_PATTERNS.md with comprehensive guides on:
  • State management patterns
  • Performance optimization
  • Error handling
  • Testing patterns
  • Migration guides (GetX, Riverpod, Bloc, MobX)
  • Best practices
• ✅ Updated README.md with new features and examples
• ✅ Updated LIBRARY_REVIEW.md with current status

Breaking Changes #

• ⚠️ SwiftFuture constructor now accepts optional parameters (backwards compatible)
• ⚠️ Computed constructor now accepts optional enableMemoization parameter (backwards compatible)
• ⚠️ SwiftTween constructor now accepts optional vsync parameter (backwards compatible)

Notes #

• All new features are backwards compatible
• Performance improvements are opt-in (memoization, AnimationController)
• Error handling improvements are automatic but configurable
