########## RELEASE_NOTES.rst: ########## @@ -21,6 +21,174 @@ .. towncrier release notes start +Airflow 2.6.0 (2023-04-20) +-------------------------- + +Significant Changes +^^^^^^^^^^^^^^^^^^^ + +Default permissions of file task handler log directories and files has been changed to "owner + group" writeable (#29506). +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + Default setting handles case where impersonation is needed and both users (airflow and the impersonated user) + have the same group set as main group. Previously the default was also other-writeable and the user might choose + to use the other-writeable setting if they wish by configuring ``file_task_handler_new_folder_permissions`` + and ``file_task_handler_new_file_permissions`` in ``logging`` section. + +SLA callbacks no longer add files to the dag processor manager's queue (#30076) +""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + This stops SLA callbacks from keeping the dag processor manager permanently busy. It means reduced CPU, + and fixes issues where SLAs stop the system from seeing changes to existing dag files. Additional metrics added to help track queue state. + +The ``cleanup()`` method in BaseTrigger is now defined as asynchronous (following async/await) pattern (#30152). +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + This is potentially a breaking change for any custom trigger implementations that override the ``cleanup()`` + method and uses synchronous code, however using synchronous operations in cleanup was technically wrong, + because the method was executed in the main loop of the Triggerer and it was introducing unnecessary delays + impacting other triggers. The change is unlikely to affect any existing trigger implementations. + +The gauge ``scheduler.tasks.running`` no longer exist (#30374) +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + The gauge has never been working and its value has always been 0. Having an accurate + value for this metric is complex so it has been decided that removing this gauge makes + more sense than fixing it with no certainty of the correctness of its value. + +Consolidate handling of tasks stuck in queued under new ``task_queued_timeout`` config (#30375) +""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + Logic for handling tasks stuck in the queued state has been consolidated, and the all configurations + responsible for timing out stuck queued tasks have been deprecated and merged into + ``[scheduler] task_queued_timeout``. The configurations that have been deprecated are + ``[kubernetes] worker_pods_pending_timeout``, ``[celery] stalled_task_timeout``, and + ``[celery] task_adoption_timeout``. If any of these configurations are set, the longest timeout will be + respected. For example, if ``[celery] stalled_task_timeout`` is 1200, and ``[scheduler] task_queued_timeout`` + is 600, Airflow will set ``[scheduler] task_queued_timeout`` to 1200. + +Improvement Changes +^^^^^^^^^^^^^^^^^^^ + +Display only the running configuration in configurations view (#28892) +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + The configurations view now only displays the running configuration. Previously, the default configuration + was displayed at the top but it was not obvious whether this default configuration was overridden or not. + Subsequently, the non-documented endpoint ``/configuration?raw=true`` is deprecated and will be removed in + Airflow 3.0. The HTTP response now returns an additional ``Deprecation`` header. The ``/config`` endpoint on + the REST API is the standard way to fetch Airflow configuration programmatically. + +Explicit skipped states list for ExternalTaskSensor (#29933) +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + ExternalTaskSensor now has an explicit ``skipped_states`` list + +Miscellaneous Changes +^^^^^^^^^^^^^^^^^^^^^ + +Handle OverflowError on exponential backoff in next_run_calculation (#28172) +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + Maximum retry task delay is set to be 24h (86400s) by default. You can change it globally via ``core.max_task_retry_delay`` + parameter. + +Move Hive macros to the provider (#28538) +""""""""""""""""""""""""""""""""""""""""" + The Hive Macros (``hive.max_partition``, ``hive.closest_ds_partition``) are available only when Hive Provider is + installed. Please install Hive Provider > 5.1.0 when using those macros. + +New Features +^^^^^^^^^^^^ +- Add serializer for pandas dataframe (#30390) +- Deferrable ``TriggerDagRunOperator`` (#30292) +- Adding ContinuousTimetable and support for @continuous schedule_interval (#29909) +- Allow customized rules to check if a file has dag (#30104) +- Add a new Airflow conf to specify a SSL ca cert for Kubernetes client (#30048) +- Bash sensor has an explicit retry code (#30080) +- Add filter task upstream/downstream to grid view (#29885) +- Add testing a connection via Airflow CLI (#29892) +- Support deleting the local log files when using remote logging (#29772) +- ``Blocklist`` to disable specific metric tags or metric names (#29881) +- Add a new graph inside of the grid view (#29413) +- Add database ``check_migrations`` config (#29714) +- add output format arg for ``cli.dags.trigger`` (#29224) +- Make json and yaml available in templates (#28930) +- Enable tagged metric names for existing Statsd metric publishing events | influxdb-statsd support (#29093) +- Add HttpHookAsync for deferrable implementation (#29038) +- Add arg --yes to ``db export-archived`` command.
