New Features

• Embedded Tutorial Dataset - California Schools dataset now bundled with installation and integrated into datus-agent init workflow for hands-on learning of contextual data engineering. #277 tutorial
• Enhanced Evaluation Framework - New evaluation command with expanded categories: Exact Match, Same Result Count (different values), Schema/Table Usage Match, and Semantic/Metric Layer Correctness. #264
• Plugin-Based Database Connector - Refactored database connector to plugin-based architecture for easier extensibility and custom adapter development. #284

Enhancements

• Simplified Installation - Removed legacy transformers dependency from default installation for faster setup and reduced package size. #247
• Streamlined MetricFlow Configuration - Simplified configuration as MetricFlow now natively supports Datus config format. #243
• Built-in Generation Commands - /gen_semantic_model, /gen_metrics, and /gen_sql_summary subagents now work out of the box without additional setup. #250
• Agentic Node Integration - Workflow-based evaluations now support agentic nodes for more sophisticated testing scenarios. #262
• Code Quality Improvements - Refactored tool modules and enhanced node logic. Unified bootstrap-kb and gen_semantic_model to use the same implementation. #245 #250
• Optimized Embedding Storage - Refactored embedding model storage and updated dependencies for better performance. #247

Bug Fixes
