1.13.0 (core) / 0.29.0 (libraries)

on GitHub

Major Changes Since 1.12.0

• AI-assisted development: Released dagster-io/skills, a collection of Dagster-focused AI skills for coding agents like Claude Code, OpenAI Codex, and others. Expanded dg api commands for programmatic inspection of assets, runs, jobs, schedules, and more.
• Partitioned asset checks: Asset checks can now target specific partitions of an upstream asset, aligning data quality logic with how partitioned data is produced and monitored.
• State-backed components enabled by default: Integrations that depend on external metadata (dbt, Fivetran, Airbyte, Tableau, Looker, etc.) now use persisted local state by default, providing a more predictable code location loading experience.
• Virtual assets (preview): New is_virtual parameter on @asset and AssetSpec for modeling assets like database views that automatically reflect upstream changes without explicit materialization.
• 20+ new components: Added or expanded components for dbt Cloud, Spark, Azure (Blob Storage, ADLS2), GCP (BigQuery, GCS, Dataproc), Databricks, Tableau, Looker, Census, Polytomic, and more. Integrations gained richer observability, metadata, and operational support.
• Deeper integration support: dbt Cloud supports partitioned assets; Databricks gained job-level subsetting and auto-cancel on run termination; Fivetran added polling sensors, retry-on-reschedule, and resync support; BI integrations auto-enrich assets with table metadata for cross-system lineage.
• Dagster+ improvements: Organization-level timezone settings, service users for Pro accounts, more resilient code server redeploy behavior, improved agent failure recovery, and expanded insights and alerting workflows.

Breaking Changes

• Removed deprecated external_asset_from_spec and external_assets_from_specs. Use AssetSpec inputs directly to Definitions(...) or AssetsDefinition(specs=[...]) instead.
• Removed deprecated single-AssetKey deps argument support from asset dependencies. Use a sequence of AssetDep objects instead.
• Removed deprecated get_all_asset_specs from Definitions.
• Removed deprecated legacy_freshness_policy parameter from @observable_source_asset.
• Removed deprecated auto_observe_interval_minutes parameter from @observable_source_asset.
• Removed deprecated legacy_freshness_policies_by_output_name parameter from AssetsDefinition.
• Removed deprecated load_component_at_path from ComponentLoadContext. Use context.load_component instead.
• Removed deprecated build_defs_at_path from ComponentLoadContext.
• [dagster-airbyte] Removed deprecated AirbyteState enum (use AirbyteJobStatusType instead) and removed deprecated legacy_freshness_policy and auto_materialize_policy parameters from build_airbyte_assets().
• [dagster-looker] Removed deprecated DagsterLookerResource.build_defs, get_asset_key, get_dashboard_asset_key, get_explore_asset_key, get_view_asset_key methods, and Type[DagsterLookerApiTranslator] support from API helpers.
• [dagster-powerbi] Removed deprecated PowerBIWorkspace.build_defs(), translator key helpers (use get_asset_spec() instead), and Type[DagsterPowerBITranslator] support in load_powerbi_asset_specs() (pass an instance instead).
• [dagster-sigma] Removed deprecated SigmaOrganization.build_defs(), DagsterSigmaTranslator.get_asset_key() (use get_asset_spec(...).key instead), and Type[DagsterSigmaTranslator] support in load_sigma_asset_specs() (pass an instance instead).

New

• (Preview) Added support for virtual assets. The @asset decorator and AssetSpec now accept an is_virtual parameter for defining assets that represent views or derived tables that don't need to be materialized. Virtual assets are supported in staleness calculations, execution planning, and declarative automation.
• Job-level config defaults are now applied when partial config is provided to a run.
• [dagster-dbt] Added enable_dbt_views_as_virtual_assets setting to DbtTranslatorSettings for automatically treating dbt views as virtual assets.

Bugfixes

• Fixed an issue where a sensor targeting a job with run_tags and specifying an asset_selection in the RunRequest would not apply the job's run_tags to the resulting run.
• Fixed a potential error in YAML config snapshot conversion when encountering None fields.
• [dg] Fixed dg plus deploy configure generating a GitHub Action that used Docker instead of the PEX build strategy.
• [dagster-cloud-cli] PR comments in CI are now scoped by deployment name, preventing overwrites across deployments.
• [ui] Fixed "Missing" partition selection for time-based partitioned assets.
• [ui] Fixed raw log display rendering after ansi-to-react library update.
• [ui] "Terminate all runs" dialog now handles extremely large sets of runs more reliably.

Documentation

• Added Dagster+ agent configuration page for serverless and hybrid deployments.
• Added data portability documentation page.
• Reorganized run isolation documentation for hybrid and serverless deployments.
• Added ELT pipeline example with dlt and Sling.

Dagster Plus

• Added percent-change comparison type for metric monitor alerts.
• Added SCIM Groups filter support for members.value eq queries.
• Added MCP server integration providing AI assistants with access to Dagster Cloud operations.
• Fixed an issue where the Dagster+ Kubernetes agent would emit log noise about DAGSTER_CLOUD_RAW_GIT_URL and DAGSTER_CLOUD_GIT_URL environment variables when onlyAllowUserDefinedK8sConfigFields was set.
• Fixed incorrect alert type label for metrics alerts.
• Fixed Databricks connections failing with an "unable to start warehouse" error.
