Dagster Files

New

• Added an owners parameter to define_asset_job, mirroring the field on regular jobs.
• Improved error messages when required config is missing in Dagster jobs, with clearer guidance on which fields are missing and example config to provide.
• LOGS_CAPTURED event messages no longer say "Started capturing logs", since compute log managers typically upload logs on completion rather than streaming in real time.
• [ui] Added client-side validation for the deployment settings YAML editor that warns when unknown keys are detected.
• [ui] Op tags are now shown on the asset details page in a separate "Op tags" row, alongside the asset's own tags.
• [ui] Redesigned the sensor dry run dialog with a stacked cursor layout, copy buttons for cursor values, and an inline run config preview.
• [dagster-clickhouse] Added new dagster-clickhouse, dagster-clickhouse-pandas, and dagster-clickhouse-polars libraries with native ClickHouse resources, IO managers, and dg components.
• [dagster-cloud] The EcsUserCodeLauncher now accepts a repository_credentials config option, allowing ECR credentials to be configured at the agent or deployment level instead of only per code location.
• [dagster-postgres] Added workload identity federation (WIF) authentication for PostgreSQL via a new auth_provider config option (azure_wif, gcp_wif, or aws_wif), with optional extras dagster-postgres[azure], dagster-postgres[gcp], and dagster-postgres[aws]. The Helm chart supports WIF via global.postgresqlAuthWifEnabled. (Thanks, @JohnMav!)

• [ui] Fixed the open/close behavior of the partition selector in the materialization dialog.
• [ui] Fixed false-positive syntax errors in asset selection inputs while the autocomplete dropdown was open.
• [ui] Fixed key:value autocompletion in search inputs not advancing into value-suggestion context when accepting a key with the Enter key.
• [ui] Fixed the asset catalog "Group by Owner" and "Group by Tags" views not showing assets with empty owner or tag arrays under a "None" section.

• [dagster-dbt] Fixed an issue where dbt assets configured with enable_duplicate_source_asset_keys could emit duplicate dependency entries and ambiguous source metadata when multiple dbt sources resolved to the same asset key.
• [dagster-k8s] Added a workaround for an upstream issue in the Kubernetes Python client where setting the NO_PROXY or no_proxy environment variable did not affect the configuration of Kubernetes API calls.
• [dagster-snowflake] Replaced deprecated Pydantic validator usage with field_validator to eliminate Pydantic deprecation warnings.
