- Performance boost for large asset graph loading; new unit‑testable @asset check functions, UPathIOManager.load_partitions, and expanded Polars support (multi‑partition, non‑string columns).
- Multiple bug fixes across Airbyte, K8s, DBT, UI run deletion, partition freshness, and Cloud agent shutdown behavior.
- Breaking change: PolarsDeltaIOManager now requires loading DeltaLake tables as a single DataFrame; docs renamed to Dagster+ and added sections on change tracking, metrics, and asset owners.
