Cosmos 1.6.0 has been released, introducing new features and enhancements for the community. The update allows users to integrate dbt-core jobs into Airflow by automatically creating Airflow tasks from dbt models. Key additions include a new way of rendering source nodes as Airflow tasks through the RenderConfig API, persisting the virtual environment directory for LoadMode.VIRTUALENV, and better support for using remote manifest files in GCS/S3/Azure Blob Storage. Additionally, Cosmos 1.6 supports caching dbt package-lock.yml file to ensure predictable installation of project dependencies and enhance performance.
