Dear Airflow Community, I am excited to announce the availability of Apache Airflow 3.1.0.beta1 for testing! Airflow 3.1 builds upon the solid foundation of Airflow 3.0, introducing powerful new capabilities for human-in-the-loop workflows, enhanced internationalization, and significant improvements to the user experience.
First, a few caveats: This is a beta release, so do not run it in production. It may contain significant issues, and you will likely need to reset your database between this and subsequent beta or release candidate versions. (Consider yourself warned!) This release is intended for Airflow developers only to test the build and start preparing for Airflow 3.1.0. This is not an official release, that will happen when we create a release candidate and hold a vote. The expected timeline for the first release candidate is end of next week, but we encourage early feedback to help stabilize the release. What's new in Airflow 3.1? Airflow 3.1.0 introduces significant enhancements while maintaining compatibility with Airflow 3.0 deployments.
