Dear Airflow Community, I am excited to announce the availability of Apache Airflow 3.3.0b2 for testing!
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 3.3.0. This is not an official release — that will happen when we create a release candidate and hold a vote. What's new in Airflow 3.3? Airflow 3.3.0 introduces significant enhancements while maintaining compatibility with Airflow 3.2 deployments.
