Dagster version 1.3 is now available on Dagster Cloud and in Open Source, featuring several key improvements including the official induction of Pythonic Config and Resources as a permanent part of the system, enhancements to Software-Defined Assets for tracking changes, auto-materialization, partitions, and backfill functionality, and updated documentation. The new release includes UI improvements such as clearer labels for tracking changes, a new page for monitoring asset backfills, and reorganized Dagster Cloud docs. The team is grateful for community contributions to the project, who provide valuable input by suggesting new features, submitting PRs, and helping identify and document bugs.
