+1 (non-binding) Thanks for preparing the release!
I tested 3.4.0rc1 from PyPI against Airflow 3.4.0 in Breeze (SQLite, example Dags), and the official smoke test passed. I also ran a few extra checks: the client loads the details of all 246 example Dags, as well as Dag runs and task instances, and the new 3.4.0 features I tried work as expected (draining a Dag, filtering Dag runs by tags, the is_scheduled filter, asset events by partition_key, job filters, Dag version diff and bundle details). The SHA-512 of the SVN wheel matches, and the wheel installs and passes the same smoke test. One non-blocking note: the "Non-interactive smoke test" commands in the release guide don't work as written. The version variable is set on the host and never reaches the Breeze container, and the wheel path should be /dist instead of /opt/airflow/dist. The airflowctl guide has the same issue. This only affects the docs, not the release, and I opened a PR to update it: https://github.com/apache/airflow/pull/76870 Best, Kevin On Mon, Nov 9, 2026 at 7:14 AM Rahul Vats <[email protected]> wrote: > Hey fellow Airflowers, > > The release candidate for Apache Airflow Python Client 3.4.0rc1 is now > available for testing! > > This email is calling for a vote on the release, which will last at least > 72 hours, from Mon, Nov 9, 2026 at 12:00 PM UTC > until Thursday, Nov 12, 2026 at 12:00 PM UTC, and until 3 binding +1 votes > have been received. > > Consider this my (binding) +1. > > Airflow Client 3.4.0rc1 is available at: > https://dist.apache.org/repos/dist/dev/airflow/clients/python/3.4.0rc1/ > > The apache_airflow_client-3.4.0.tar.gz is an sdist release that contains > INSTALL instructions, and also > is the official source release. > > The apache_airflow_client-3.4.0-py3-none-any.whl is a binary wheel release > that pip can install. > > Those packages do not contain .rc* version as, when approved, they will be > released as the final version. > > The rc packages are also available at PyPI (with rc suffix) and you can > install it with pip as usual: > https://pypi.org/project/apache-airflow-client/3.4.0rc1/ > > Public keys are available at: > https://dist.apache.org/repos/dist/release/airflow/KEYS > > Only votes from PMC members are binding, but all members of the community > are encouraged to test the release and vote with "(non-binding)". > > The test procedure for PMC members is described in: > > https://github.com/apache/airflow/blob/main/dev/README_RELEASE_PYTHON_CLIENT.md\#verify-the-release-candidate-by-pmc-members > > The test procedure for contributors and members of the community who would > like to test this RC is described in: > > https://github.com/apache/airflow/blob/main/dev/README_RELEASE_PYTHON_CLIENT.md\#verify-the-release-candidate-by-contributors > > *Changelog:* > > ## New Features: > > -
