Summary

The ATLAS v2026.05 release splits versioning into two tracks: monthly content releases use YYYY.MM.N, and data format changes use semantic versioning. Content v2026.05 updates all techniques to include one or more platforms (Predictive AI, Generative AI, Agentic AI, Enterprise), and format v6.0.0 introduces a new ATLAS YAML format with a platforms field on techniques, Pydantic and SQLAlchemy schemas, and a FastAPI REST API for managing ATLAS data.
