- Added @asset hooks argument, multi‑asset pool support, and DagsterDbtTranslator get_asset_check_spec customization; introduced AirbyteCloudWorkspaceComponent and backfill daemon thread‑pool configuration.
- Fixed numerous bugs: AssetCheckSpec blocking behavior, GraphDefinition.to_job with custom IO manager keys, .allow/.ignore propagation, cross‑location asset sync reporting, dagster dev loading errors, and UI step‑log upload hangs.
- Breaking UI changes: legacy Auto‑materialize tab moved, Asset Health and Resources tabs hidden for Observe UI users.
