- Agents can [inspect transform graphs via MCP](https://rerun.io/docs/reference/viewer/mcp#inspecting-transforms) with `rerun_get_transform_graph`
- [Catalog API improvements](https://rerun.io/docs/concepts/query-and-transform/catalog-object-model#managing-segment-layers-with-the-python-catalog-api): `Segment` and `Layer` handles, `DatasetEntry.schema()`, and [`DatasetEntry.info()`](https://rerun.io/docs/howto/query-and-transform/get-data-out#getting-an-overview)
- The selection panel shows which [layers](https://rerun.io/docs/howto/logging-and-ingestion/layers) a component comes from
