+## [0.2.0] - 2025-10-15
+
+### Added
+- **8-Feature Model**: Complete upgrade to production-ready 8-feature phishing detection
+  - `IsHTTPS`: Binary HTTPS indicator for security baseline
+  - `TLDLegitimateProb`: Bayesian TLD legitimacy probability with 1401+ TLD dataset
+  - `CharContinuationRate`: Character repetition pattern detection
+  - `SpacialCharRatioInURL`: Special character density analysis
+  - `URLCharProb`: URL character sequence probability scoring
+  - `LetterRatioInURL`: Alphabetic character ratio for readability assessment
+  - `NoOfOtherSpecialCharsInURL`: Special character count for complexity analysis
+  - `DomainLength`: RFC-compliant domain length validation
+- **Enhanced Judge System**: Modernized LLM integration with 8-feature model
+  - Updated judge contracts to use production features
+  - Enhanced stub logic with sophisticated heuristics
+  - Improved LLM prompts with detailed feature descriptions
+  - Graceful fallback from modern to legacy features
+- **Comprehensive Test Suite**: 52 tests with 100% pass rate
+  - Updated all tests for 8-feature model compatibility
+  - Enhanced integration tests for microservice communication
+  - Modernized judge system tests with production features
+  - Fixed whitelist behavior validation
+
+### Changed
+- **Great Expectations**: Updated data validation for 8-feature model
+  - Migrated from 3-feature legacy validation to 8-feature production validation
+  - Updated thresholds and expectations for new feature ranges
+  - Enhanced data contract validation with feature-specific checks
+- **Judge System Architecture**: Complete alignment with production features
+  - FeatureDigest contract updated with 8 required + 3 optional legacy fields
+  - Enhanced decision logic using modern feature signals
+  - Improved context and audit trail with comprehensive feature logging
+- **GitHub Workflows**: Updated CI/CD for modern project structure
+  - Enhanced data contract workflow with 8-feature model support
+  - Updated CI workflow with better error reporting
+  - Added fallback logic for legacy data file compatibility
+
+### Removed
+- **Feature Service**: Eliminated redundant microservice
+  - Removed `src/feature_svc/` directory and related code
+  - Updated Docker compose to remove feature service dependency
+  - Cleaned up unused `docker/feature.Dockerfile`
+  - Streamlined architecture to gateway + model services only
+- **Legacy Scripts**: Deprecated obsolete feature extraction
+  - Identified `scripts/materialize_url_features.py` as obsolete
+  - Removed references to deprecated 3-feature model components
+
+### Fixed
+- **Docker Configuration**: Enhanced for 8-feature model deployment
+  - Added `data/` directory to Docker images for TLD probability data
+  - Updated environment variables for proper service communication
+  - Fixed `.dockerignore` to include necessary data files
+- **Test Infrastructure**: Resolved all compatibility issues
+  - Fixed whitelist behavior in integration tests
+  - Updated API contract expectations for current implementation
+  - Resolved version mismatches and dependency issues
+  - Enhanced test reliability with non-whitelisted test domains
+
+### Technical Details
+- **Feature Engineering**: Advanced URL-only features with statistical and linguistic analysis
+- **Data Validation**: 31 comprehensive Great Expectations rules for production data quality
+- **Performance**: Maintained 204ms API response time with enhanced feature extraction
+- **Compatibility**: Backward compatibility maintained through optional legacy feature support
