1.6.6 (core) / 0.22.6 (libraries)

New

• Dagster officially supports Python 3.12.
• dagster-polars has been added as an integration. Thanks @danielgafni!
• [dagster-dbt] @dbt_assets now supports loading projects with semantic models.
• [dagster-dbt] @dbt_assets now supports loading projects with model versions.
• [dagster-dbt] get_asset_key_for_model now supports retrieving asset keys for seeds and snapshots. Thanks @aksestok!
• [dagster-duckdb] The Dagster DuckDB integration supports DuckDB version 0.10.0.
• [UPath I/O manager] If a non-partitioned asset is updated to have partitions, the file containing the non-partitioned asset data will be deleted when the partitioned asset is materialized, rather than raising an error.

Bugfixes

• Fixed an issue where creating a backfill of assets with dynamic partitions and a backfill policy would sometimes fail with an exception.
• Fixed an issue with the type annotations on the @asset decorator causing a false positive in Pyright strict mode. Thanks @tylershunt!
• [ui] On the asset graph, nodes are slightly wider allowing more text to be displayed, and group names are no longer truncated.
• [ui] Fixed an issue where the groups in the asset graph would not update after an asset was switched between groups.
• [dagster-k8s] Fixed an issue where setting the security_context field on the k8s_job_executor didn't correctly set the security context on the launched step pods. Thanks @krgn!

Experimental

• Observable source assets can now yield ObserveResults with no data_version.
• You can now include FreshnessPolicys on observable source assets. These assets will be considered “Overdue” when the latest value for the “dagster/data_time” metadata value is older than what’s allowed by the freshness policy.
• [ui] In Dagster Cloud, a new feature flag allows you to enable an overhauled asset overview page with a high-level stakeholder view of the asset’s health, properties, and column schema.

Documentation

• Updated docs to reflect newly-added support for Python 3.12.

Dagster Cloud

• [kubernetes] Fixed an issue where the Kubernetes agent would sometimes leave dangling kubernetes services if the agent was interrupted during the middle of being terminated.
