Dagster version 1.4, codenamed "Material Girl", has been released on Dagster Cloud and in Open Source, introducing several key enhancements including improved dbt integration, evolving asset materialization, and a new UI layout. The release includes brand new capabilities for dbt users such as a new `@dbt-assets` decorator and scaffolding command line interface, allowing more control over how Dagster runs dbt projects. Additionally, the release introduces features like auto-materialization history, op-level concurrency limits, and experimental new features to improve ergonomics, making it more logical and accessible for users. The 1.4 contributors are thanked, and feedback is encouraged through various channels including the Dagster community Slack and GitHub discussion.
