+## Recent Improvements (v0.3.9+)
+
+The security audit system has been significantly enhanced based on comprehensive code review feedback:
+
+### 🔧 **Enhanced Reliability**
+- **UUID-based Finding IDs**: Eliminated collision risks with cryptographically unique identifiers
+- **Dependency Optimization**: Updated 51+ packages to reduce conflicts and improve stability
+- **AI Error Rate Limiting**: Prevents log flooding with intelligent 30-second throttling
+
+### 🎯 **Improved Accuracy**
+- **Context-Aware Solana Detection**: Reduced false positives in base58 key detection
+- **Enhanced Security Patterns**: Improved regex patterns for command injection and path traversal
+- **Smart Environment Validation**: Better API key handling with user-friendly guidance
+
+### 📊 **Extended Format Support**
+- **JSON Reports**: Machine-readable format for integration and automation
+- **HTML Reports**: Interactive web-based audit reports
+- **Markdown Summaries**: Perfect for documentation and GitHub integration
+- **Legacy Support**: Typst and PDF formats remain fully supported
+
+### 🤖 **Better AI Integration**
+- **Intelligent Fallback**: Clear user communication when AI analysis is unavailable
+- **Status Transparency**: Real-time feedback on AI enhancement success/failure rates
+- **Graceful Degradation**: Audit continues seamlessly even with AI service issues
+
+### ⚡ **Performance Optimizations**
+- **Single-Pass Parsing**: Optimized code analysis with shared parsed data
+- **Efficient Pattern Matching**: Cached regex compilation for faster scanning
+- **Reduced Resource Usage**: Minimized redundant operations across audit checks
