+
+### Documentation
+
+- **[Production Docker Guide](docker-image/README-DOCKER-PRODUCTION.md)** - Complete deployment guide
+- **[Security Documentation](docs/deployment/SECURITY.md)** - Security best practices
+- **[Monitoring Runbook](docs/deployment/MONITORING.md)** - Operational procedures
+- **[Disaster Recovery Plan](docs/deployment/DISASTER-RECOVERY.md)** - Recovery procedures
+
+### Breaking Changes
+
+- **Docker infrastructure** requires Docker 24.0+ with Compose
+- **Production deployments** should use new Docker infrastructure instead of legacy make commands
+- **Environment variables** for production deployment have changed (see migration guide)
+- **Network architecture** updated for security and performance (overlay networks required)
+
+### Migration Guide
+
+#### From v1.x to v2.0
+
+1. **Update Docker version** to 24.0+
+2. **Generate new secrets** using the secrets manager
+3. **Update environment variables** for production deployment
+4. **Migrate to new Docker Compose files** for production deployments
+5. **Configure monitoring stack** if using production features
+
+```bash
+# Migration steps
+git pull origin main
+./docker-image/scripts/secrets-manager.sh generate
+./docker-image/deploy-production.sh --environment production --deploy
+```
+
+### Deprecated
+
+- **Legacy production deployment** with basic Docker Compose (still available but not recommended)
+- **Basic monitoring** without Prometheus/Grafana (monitoring now comprehensive)
+- **Manual secret management** (now automated with rotation)
+
+### Technical Debt Addressed
+
+- **Large file refactoring** - Split 34 files >500 lines into focused modules
+- **Documentation coverage** - Added comprehensive documentation for all features
+- **Security gaps** - Implemented enterprise-grade security measures
+- **Monitoring blind spots** - Added comprehensive observability stack
+- **Deployment complexity** - Automated with production-grade scripts
