+  - Phase 1: Discovery - Scan target for injection points
+  - Phase 2: Attack - Execute patterns sequentially
+  - Phase 3: Verification - Analyze responses with detection framework
+  - Phase 4: Reporting - Generate multi-format reports
+- Proper phase ordering enforcement with explicit wait points
+- Comprehensive error handling with custom exception hierarchy
+- Clean resource management with try/finally blocks
+
+#### Configuration
+
+- **Type-Safe Configuration** using Pydantic v2
+  - `TargetConfig` - Target endpoint configuration
+  - `AttackConfig` - Attack pattern selection and rate limiting
+  - `ReportingConfig` - Output format and path configuration
+- YAML configuration file support with environment variable expansion (`${VAR}`)
+- CLI argument to Pydantic model conversion
+- Configuration validation with helpful error messages
+
+#### Reporting
+
+- **Multi-Format Report Generation**
+  - **JSON** - Clean JSON with configurable formatting
+  - **YAML** - Human-readable YAML output
+  - **HTML** - Professional HTML reports with:
+    - Embedded CSS (no external dependencies)
+    - Responsive design (desktop/mobile/print)
+    - Color-coded severity levels
+    - Summary dashboard with statistics
+    - Detailed test results with evidence
+- Abstract `ReportFormatter` base class for extensibility
+- `save_report()` convenience function with format auto-detection
+- Report metadata tracking (timestamp, duration, target info)
+
+#### Testing
+
+- Integration test suite ([tests/integration/test_pipeline.py](tests/integration/test_pipeline.py))
+  - Pipeline structure validation

+  - Format-specific validation
+  - Element presence checks
+

+
+### Changed
+
+- **Breaking**: Complete re-architecture from v1.x
+- **Breaking**: CLI interface updated (now using Typer instead of argparse)
+- **Breaking**: Configuration format changed (now using Pydantic v2)
+- **Breaking**: Import paths changed (new modular structure)
+- Discovery phase now uses real `InjectionTester.discover_injection_points()`

+- Resource management ensures proper cleanup in all phases
+
+### Fixed
+
+- **Critical**: Eliminated tool use concurrency errors through sequential execution
+- Proper cleanup of InjectionTester instances with try/finally blocks
+- Race conditions in pattern execution
+- Memory leaks from unclosed HTTP clients
+- Inconsistent error messages
+- Missing type hints throughout codebase
+
+### Dependencies

+- Added `jinja2>=3.1.0` - HTML template rendering
+- Updated `typer>=0.9.0` - Modern CLI framework
+- Updated `rich>=13.0.0` - Terminal UI enhancements
+- Maintained `aiohttp>=3.9.0` - Core framework compatibility
+- Maintained `pyyaml>=6.0` - Configuration file support
+
+### Security
+
+- Comprehensive security scanning in CI/CD pipeline
+- Input validation using Pydantic models
+- Safe YAML loading with `yaml.safe_load()`
+- Environment variable expansion for sensitive data
+- No hardcoded credentials or API keys
+- Proper error handling to avoid information disclosure
+
+### Performance
+
+- Sequential execution prevents race conditions while maintaining efficiency
+- Rate limiting respects API constraints
+- Efficient resource cleanup
+- Minimal memory footprint
+- Optimized Docker image layers
+
+### Statistics
+
+- **Total Lines of Code**: ~5,000 lines (excluding tests)
+- **Test Code**: ~950 lines
+- **Documentation**: ~2,250 lines
+- **New Files Created**: 21 files
+- **Modified Files**: 4 files
+- **Report Formats**: 3 (JSON, YAML, HTML)
+- **Patterns Supported**: 20+ built-in patterns
+
+## [1.x] - Previous Versions
+
+### Legacy Implementation
+
+Previous versions (1.x) featured:
+
+- Basic CLI with argparse
