Dagster 1.6 has been released, bringing several major enhancements to the tool. The UI has seen significant upgrades, including a dark mode feature that matches the user's system theme, and improvements to the asset lineage graph, such as easier visualization and navigation of large graphs. Other new features include report asset materializations from the UI, backfill previews, triggered run tracking, and sensor or schedule tick logs accessible by default. Additionally, three new APIs, MaterializeResult, AssetSpec, and AssetDep, have been marked as stable after being previously in an "experimental" status. Dagster Pipes have also seen improvements, including easier integration with AWS Lambda, report arbitrary messages between pipes processes, and termination forwarding. The development team would like to thank all the community members who contributed to Dagster since the 1.5 release.
