- Introduced AI‑assisted development with Dagster Skills and added virtual asset support (is_virtual flag) for modeling views without materialization.
- Enabled state‑backed components by default, expanded integrations (dbt, Spark, Azure, GCP, Databricks, Tableau, Looker, etc.) and added partitioned asset checks and new components.
- Removed numerous deprecated APIs and parameters (external assets, legacy freshness policies, AirbyteState, etc.) and fixed several bugs in sensors, UI, CI, and deployment tooling.
