- Added checkpointing for sensor daemon failures, a run‑tags argument for build contexts, and support for nested partially configured resources outside definitions.
- Enhanced the UI with GraphiQL, timeline grouping, merged automations table, log filtering, and fixed several bugs (backfill duplication, run state handling, timeline/tooltips, UI dialogs).
- Breaking change: AirbyteCloudResource now requires client‑id/client‑secret (API key removed); also deprecated Databricks auth clients and several Sling resources/methods.
