Hey fellow Airflowers, We have cut Airflow 2.9.0b1 now that all the main features have been included.
Note: apache-airflow-providers-fab==1.0.2b0 must be installed alongside this snapshot for Airflow to work. This "snapshot" is intended for members of the Airflow developer community to test the build and allow early testing of 2.9.0. Please test this beta and create GitHub issues wherever possible if you encounter bugs, (use 2.9.0b1 in the version dropdown filter when creating the issue). For clarity, this is not an official release of Apache Airflow either - that doesn't happen until we make a release candidate and then vote on that. Airflow 2.9.0b1 is available at: https://dist.apache.org/repos/dist/dev/airflow/2.9.0b1/ *apache-airflow-2.9.0-source.tar.gz* is a source release that comes with INSTALL instructions. *apache-airflow-2.9.0.tar.gz* is the binary Python "sdist" release. *apache_airflow-2.9.0-py3-none-any.whl* is the binary Python wheel "binary" release. This snapshot has been pushed to PyPI too at https://pypi.org/project/apache-airflow/2.9.0b1/ and can be installed by running the following command: pip install 'apache-airflow==2.9.0b1' *Constraints files* are available at https://github.com/apache/airflow/tree/constraints-2.9.0b1 Release Notes: https://github.com/apache/airflow/blob/2.9.0b1/RELEASE_NOTES.rst *Changes since 2.8.4rc1:* *Significant Changes* *Following Listener API methods are considered stable and can be used for production system (were experimental feature in older Airflow versions) (#36376):* Lifecycle events: - ``on_starting`` - ``before_stopping`` DagRun State Change Events: - ``on_dag_run_running`` - ``on_dag_run_success`` - ``on_dag_run_failed`` TaskInstance State Change Events: - ``on_task_instance_running`` - ``on_task_instance_success`` - ``on_task_instance_failed`` *Support for Microsoft SQL-Server for Airflow Meta Database has been removed (#36514)* After discussion <https://lists.apache.org/thread/r06j306hldg03g2my1pd4nyjxg78b3h4> and a voting process <https://lists.apache.org/thread/pgcgmhf6560k8jbsmz8nlyoxosvltph2>, the Airflow's PMC and Committers have reached a resolution to no longer maintain MsSQL as a supported Database Backend. As of Airflow 2.9.0 support of MsSQL has been removed for Airflow Database Backend. A migration script which can help migrating the database *before* upgrading to Airflow 2.9.0 is available in airflow-mssql-migration repo on Github <https://github.com/apache/airflow-mssql-migration>. Note that the migration script is provided without support and warranty. This does not affect the existing provider packages (operators and hooks), DAGs can still access and process data from MsSQL. *Dataset URIs are now validated on input (#37005)* Datasets must use a URI that conform to rules laid down in AIP-60, and the value will be automatically normalized when the DAG file is parsed. See `documentation on Datasets < https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/datasets.html>`_ for a more detailed description on the rules. You may need to change your Dataset identifiers if they look like a URI, but are used in a less mainstream way, such as relying on the URI's auth section, or have a case-sensitive protocol name. *The method ``get_permitted_menu_items`` in ``BaseAuthManager`` has been renamed ``filter_permitted_menu_items`` (#37627)* *Add REST API actions to Audit Log events (#37734)* The Audit Log ``event`` name for REST API events will be prepended with ``api.`` or ``ui.``, depending on if it came from the Airflow UI or externally. *Airflow 2.9.0 is the first release that officially supports Python 3.12 (#38025)* There are a few caveats though: * Pendulum2 does not support Python 3.12. For Python 3.12 you need to use `Pendulum 3 < https://pendulum.eustace.io/blog/announcing-pendulum-3-0-0.html>`_ * Minimum SQLAlchemy version supported when Pandas is installed for Python 3.12 is ``1.4.36`` released in April 2022. Airflow 2.9.0 increases the minimum supported version of SQLAlchemy to ``1.4.36`` for all Python versions. Not all Providers support Python 3.12. At the initial release of Airflow 2.9.0 the following providers are released without support for Python 3.12: * ``apache.beam`` - pending on `Apache Beam support for 3.12 < https://github.com/apache/beam/issues/29149>`_ * ``papermill`` - pending on Releasing Python 3.12 compatible papermill client version `including this merged issue < https://github.com/nteract/papermill/pull/771>`_ *New Features* - Add ``Matomo`` as an option for analytics_tool.
