Fixed #

• CRITICAL: Fixed data persistence between application sessions
• WAL recovery now properly restores data on database reopening
• Fixed async operations in WAL write operations
• Fixed operation ordering to maintain data consistency
• Improved tombstone handling for deleted entries

Acknowledgments #

• Thanks to Ray Caruso for reporting the critical persistence bug

Fixed #

• Fixed pub.flutter-io.cn static analysis issues
• Better error handling in code
• Improved code quality

Added #

• API documentation for all public methods

Fixed #

• Minor fixes and code improvements

Added #

• WASM Compatibility: Full support for Dart's WASM runtime with automatic fallback encryption
• Enhanced Encryption API: New EncryptionType enum for better encryption control
• Encryption Factory Methods: DatabaseConfig.withXorEncryption() and DatabaseConfig.withAes256Encryption()
• WASM Fallback Encryption: HMAC-based encryption for WASM environments when PointyCastle is unavailable
• Runtime Detection: Automatic detection of WASM runtime with appropriate warnings
• Encryption Metadata: Enhanced metadata including runtime environment and fallback status

Improved #

• AES-256 Performance: 40% faster AES encryption (138-180ms vs 237ms) using PointyCastle 4.0.0
• WAL Recovery: Fixed Write-Ahead Log recovery issues with proper pending write flushing
• Code Documentation: Updated README with new encryption API examples and WASM compatibility section

Fixed #

• WAL Test Failures: Resolved race conditions in Write-Ahead Log tests
• Tombstone Recovery: Fixed delete entry recovery in WAL mixed operations
• Async Flush Issues: Improved pending write flushing in WAL close operations

Technical #
