Dear Airflow Community, I am excited to announce the availability of Apache Airflow 3.4.0.beta1 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 3.4.0. This is not an official release, that will happen when we create a release candidate and hold a vote. What's new in Airflow 3.4? Airflow 3.4.0 introduces significant enhancements including Task Loops (AIP-111), the ability to author DAGs in languages other than Python via the Dag Importer (AIP-85). Please note that Python 3.10 is no longer supported in this release. the supported versions are Python 3.11 to 3.14. Please refer to the release notes below for details. *Docs* (for preview): https://airflow.staged.apache.org/docs/apache-airflow/3.4.0/release_notes.html#airflow-3-4-0-2026-11-02 *Release Notes*:- https://github.com/apache/airflow/blob/3.4.0b1/RELEASE_NOTES.rst *Testing Instructions using PyPI*: You can build a virtualenv that installs this and other required packages (e.g. task sdk), like this: ``` uv venv uv pip install -U \ apache-airflow==3.4.0b1 \ apache-airflow-core==3.4.0b1 \ apache-airflow-task-sdk==1.4.0b1 ``` Constraints files are at https://github.com/apache/airflow/tree/constraints-3.4.0b1 The beta snapshot is available at our SVN: https://dist.apache.org/repos/dist/dev/airflow/3.4.0b1/ and https://dist.apache.org/repos/dist/dev/airflow/task-sdk/1.4.0b1/ Public keys for verification are available at: https://www.apache.org/dist/airflow/KEYS *Get Involved* We encourage the community to test this release and report any issues or feedback.
