New

• When an exception is wrapped by another exception and raised within an op, Dagit will now display the full chain of exceptions, instead of stopping after a single exception level.
• A default_logger_defs argument has been added to the @repository decorator. Check out the docs on specifying default loggers to learn more.
• AssetsDefinition.from_graph and AssetsDefinition.from_op now both accept a partition_mappings argument.
• AssetsDefinition.from_graph and AssetsDefinition.from_op now both accept a metadata_by_output_name argument.
• define_asset_job now accepts an executor_def argument.
• Removed package pin for gql in dagster-graphql.
• You can now apply a group name to assets produced with the @multi_asset decorator, either by supplying a group_name argument (which will apply to all of the output assets), or by setting the group_name argument on individual AssetOuts.
• InputContext and OutputContext now each have an asset_partitions_def property, which returns the PartitionsDefinition of the asset that’s being loaded or stored.
• build_schedule_from_partitioned_job now raises a more informative error when provided a non-partitioned asset job
• PartitionMapping, IdentityPartitionMapping, AllPartitionMapping, and LastPartitionMapping are exposed at the top-level dagster package. They're currently marked experimental.
• When a non-partitioned asset depends on a partitioned asset, you can now control which partitions of the upstream asset are used by the downstream asset, by supplying a PartitionMapping.
• You can now set PartitionMappings on AssetIn.
• [dagit] Made performance improvements to the loading of the partitions and backfill pages.
• [dagit] The Global Asset Graph is back by popular demand, and can be reached via a new “View global asset lineage ”link on asset group and asset catalog pages! The global graph keeps asset in the same group visually clustered together and the query bar allows you to visualize a custom slice of your asset graph.
• [dagit] Simplified the Content Security Policy and removed frame-ancestors restriction.
• [dagster-dbt] load_assets_from_dbt_project and load_assets_from_dbt_manifest now support a node_info_to_group_name_fn parameter, allowing you to customize which group Dagster will assign each dbt asset to.
• [dagster-dbt] When you supply a runtime_metadata_fn when loading dbt assets, this metadata is added to the default metadata that dagster-dbt generates, rather than replacing it entirely.
• [dagster-dbt] When you load dbt assets with use_build_command=True, seeds and snapshots will now be represented as Dagster assets. Previously, only models would be loaded as assets.

Bugfixes

• Fixed an issue where runs that were launched using the DockerRunLauncher would sometimes use Dagit’s Python environment as the entrypoint to launch the run, even if that environment did not exist in the container.
• Dagster no longer raises a “Duplicate definition found” error when a schedule definition targets a partitioned asset job.
• Silenced some erroneous warnings that arose when using software-defined assets.
• When returning multiple outputs as a tuple, empty list values no longer cause unexpected exceptions.
• [dagit] Fixed an issue with graph-backed assets causing a GraphQL error when graph inputs were type-annotated.
• [dagit] Fixed an issue where attempting to materialize graph-backed assets caused a graphql error.
• [dagit] Fixed an issue where partitions could not be selected when materializing partitioned assets with associated resources.
• [dagit] Attempting to materialize assets with required resources now only presents the launchpad modal if at least one resource defines a config schema.

Breaking Changes

• An op with a non-optional DynamicOutput will now error if no outputs are returned or yielded for that dynamic output.
• If an Output object is used to type annotate the return of an op, an Output object must be returned or an error will result.

Community Contributions

• Dagit now displays the path of the output handled by PickledObjectS3IOManager in run logs and Asset view. Thanks @danielgafni

Documentation

• The Hacker News example now uses stable 0.15+ asset APIs, instead of the deprecated 0.14.x asset APIs.
• Fixed the build command in the instructions for contributing docs changes.
• [dagster-dbt] The dagster-dbt integration guide now contains information on using dbt with Software-Defined Assets.
