v2026.05
Summary
ATLAS v2026.05 introduces a major structural overhaul that separates versioning for content updates from format changes, moving to a new YAML format (v6.0.0) with improved consistency and relationship handling. The update adds support for multiple AI platforms (Predictive, Generative, Agentic, and Enterprise) to techniques and introduces new tooling including Pydantic schemas (strict data validation), SQLAlchemy ORM models (database storage), and a FastAPI REST API (web service for managing the data). Historical ATLAS releases have been migrated and preserved in the new structure.
