Hey, fellow Airflowers, I have cut Airflow 2.10.0b2 now that all the main features have been included.
This "snapshot" is intended for members of the Airflow developer community to test the build and allow early testing of 2.10.0. Please test this beta and create GitHub issues wherever possible if you encounter bugs (use 2.10.0b2 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 2.10.0b2 is available at: https://dist.apache.org/repos/dist/dev/airflow/2.10.0b2/ *apache-airflow-2.10.0-source.tar.gz* is a source release that comes with INSTALL instructions. *apache-airflow-2.10.0.tar.gz* is the binary Python "sdist" release. *apache_airflow-2.10.0-py3-none-any.whl* is the binary Python wheel "binary" release. Public keys are available at: https://dist.apache.org/repos/dist/release/airflow/KEYS Please vote accordingly: [ ] +1 approve [ ] +0 no opinion [ ] -1 disapprove with the reason 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_AIRFLOW.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_AIRFLOW.md\#verify-the-release-candidate-by-contributors Please note that the version number excludes the `rcX` string, so it's now simply 2.10.0. This will allow us to rename the artifact without modifying the artifact checksums when we actually release. Release Notes: https://github.com/apache/airflow/blob/2.10.0b2/RELEASE_NOTES.rst For information on what goes into a release, please see: https://github.com/apache/airflow/blob/main/dev/WHAT_GOES_INTO_THE_NEXT_RELEASE.md Changes since 2.9.3: *Significant Changes* *Datasets no longer trigger inactive DAGs (#38891)* Previously, when a DAG is paused or removed, incoming dataset events would still trigger it, and the DAG would run when it is unpaused or added back in a DAG file. This has been changed; a DAG's dataset schedule can now only be satisfied by events that occur when the DAG is active. While this is a breaking change, the previous behavior is considered a bug. The behavior of time-based scheduling is unchanged, including the timetable part of ``DatasetOrTimeSchedule``. *``try_number`` is no longer incremented during task execution (#39336)* Previously, the try number (``try_number``) was incremented at the beginning of task execution on the worker. This was problematic for many reasons. For one it meant that the try number was incremented when it was not supposed to, namely when resuming from reschedule or deferral. And it also resulted in the try number being "wrong" when the task had not yet started. The workarounds for these two issues caused a lot of confusion. Now, instead, the try number for a task run is determined at the time the task is scheduled, and does not change in flight, and it is never decremented. So after the task runs, the observed try number remains the same as it was when the task was running; only when there is a "new try" will the try number be incremented again. One consequence of this change is, if users were "manually" running tasks (e.g. by calling ``ti.run()`` directly, or command line ``airflow tasks run``), try number will no longer be incremented. Airflow assumes that tasks are always run after being scheduled by the scheduler, so we do not regard this as a breaking change. *``/logout`` endpoint in FAB Auth Manager is now CSRF protected (#40145)* The ``/logout`` endpoint's method in FAB Auth Manager has been changed from ``GET`` to ``POST`` in all existing AuthViews (``AuthDBView``, ``AuthLDAPView``, ``AuthOAuthView``, ``AuthOIDView``, ``AuthRemoteUserView``), and now includes CSRF protection to enhance security and prevent unauthorized logouts. *Support for OpenTelemetry Traces is no longer "Experimental" (#40874)* *OpenTelemetry Traces for Apache Airflow (#37948).* This new feature adds capability for Apache Airflow to emit 1) airflow system traces of scheduler, triggerer, executor, processor 2) DAG run traces for deployed DAG runs in OpenTelemetry format. Previously, only metrics were supported which emitted metrics in OpenTelemetry. This new feature will add richer data for users to use OpenTelemetry standard to emit and send their trace data to OTLP compatible endpoints. *Using Multiple Executors Concurrently (#40701)* Previously known as hybrid executors, this new feature allows Airflow to use multiple executors concurrently. DAGs, or even individual tasks, can be configured to use a specific executor that suits its needs best. A single DAG can contain tasks all using different executors. Please see the Airflow documentation for more details. Note: This feature is still experimental. *New Features* - AIP-61 Hybrid Execution (`AIP-61 < https://github.com/apache/airflow/pulls?q=is%3Apr+label%3Aarea%3Ahybrid-executors+is%3Aclosed+milestone%3A%22Airflow+2.10.0%22 >`_) - AIP-62 Getting Lineage from Hook Instrumentation (`AIP-62 < https://github.com/apache/airflow/pulls?q=is%3Apr+is%3Amerged+label%3AAIP-62+milestone%3A%22Airflow+2.10.0%22 >`_) - AIP-64 TaskInstance Try History (`AIP-64 < https://github.com/apache/airflow/pulls?q=is%3Apr+is%3Amerged+label%3AAIP-64+milestone%3A%22Airflow+2.10.0%22 >`_) - AIP-44 Internal API (`AIP-44 < https://github.com/apache/airflow/pulls?q=is%3Apr+label%3AAIP-44+milestone%3A%22Airflow+2.10.0%22+is%3Aclosed >`_) - Retrieve inlet dataset events through dataset aliases (#40809) - Extend get_datasets endpoint to include dataset aliases (#40830) - Feature/add token authentication to internal api (#40899) - Scheduling based on dataset aliases (#40693) - Add start execution from triggerer support to dynamic task mapping (#39912) - Add try_number to log table (#40739) - Added ds_format_locale method in macros which allows localizing datetime formatting using Babel (#40746) - Link dataset event to dataset alias (#40723) - Add DatasetAlias to support dynamic Dataset Event Emission and Dataset Creation (#40478) - Use sentinel to mark dag as removed on re-serialization (#39825) - Support hybrid executors in backfill jobs (#40472) - Scheduler job: main loop and event processing for multi executors (#40017) - Add parameter for the last number of queries to the DB in DAG file processing stats (#40323) - ADD prototype version dark mode for Airflow UI (#39355) - Move import to make PythonOperator working on Windows (#40424) - Dag test without sensor (#40010) - Handle db isolation for mapped operators and task groups (#39259) - feature: callable for template_fields (#37028) - Home: filter running/failed and active/paused dags (#39701) - Fix typo in example inlet events DAG (#39909) - Add example DAGs for inlet_events (#39893) - Add metrics about task CPU and memory usage (#39650) - UI changes for DAG Re-parsing feature (#39636) - Add Scarf based telemetry (#39510) - Add dag re-parsing request endpoint (#39138) - Task adoption for hybrid executors (#39531) - Redirect to new DAGRun after trigger from Grid view (#39569) - Display ``endDate`` in task instance tooltip.
