24842Default DAG schedule changed to NoneNNNNYN

N

When a schedule parameter is not passed to the DAG constructor, Airflow now defaults to never automatically schedule the DAG at all. The created DAG can still be manually triggered, either by the user directly, or from another DAG with TriggerDagRunOperator.
40029Deprecated allow_raw_html_descriptionsNNNNNYNRemove deprecated allow_raw_html_descriptions from UI Trigger forms
40931

dirrao

Deprecated store_serialized_dagsNNNN?NNRemoved dagbag deprecated store_serialized_dags parameter. Please use read_dags_from_db parameter.
40936on_success_callback no longer called if task skippedNNNNYNNon_success_callback will no longer execute if a task is skipped. Previously, this callback was triggered even when the task was skipped, which could lead to unintended behavior or inconsistencies in downstream processes. This is a breaking change because workflows that rely on on_success_callback running for skipped tasks will need to be updated. Consider updating your DAGs to handle cases where the callback is not invoked due to task skipping.
41096dirraoDeprecated process_poll_intervalNYNNNNNRemoved deprecated processor_poll_interval configuration parameter from scheduler section. Please use scheduler_idle_sleep_time configuration parameter.

AIP-74 (Rename Dataset to Asset)NYY?NNNNBig set of changes to rename Dataset to Asset. Touches many core Airflow packages. Unclear, if backward compatibility shims were added?
41366Deprecated airflow.contrib

Y

NNNNNNairflow.contrib modules have been removed.
All modules from airflow.contrib which were deprecated in Airflow 2, have been removed.

41367Deprecated ImportError NNNNNNNDeprecated ImportError removed from airflow.models
The deprecated ImportError class can no longer be imported from airflow.models. It has been moved to airflow.models.errors.ParseImportError.

41368Deprecated core imports YNNNNNNSupport for deprecated core imports removed
Support for importing classes etc from the following locations was deprecated at various times during Airflow 2s lifecycle, and has been removed:
airflow.executors
airflow.hooks
airflow.macros
airflow.operators
airflow.sensors
Instead, import from the right provider or more specific module instead. For example, instead of from airflow.sensors import TimeDeltaSensor, use from airflow.sensors.time_delta import TimeDeltaSensor.

41390Kaxil Naik 
Deprecated SubDAGs YNYYNNNSubdags have been removed from the following locations:
CLI
API
SubDagOperator
This removal marks the end of Subdag support across all interfaces. Users should transition to using TaskGroups as a more efficient and maintainable alternative. Please ensure your DAGs are updated to remove any usage of Subdags to maintain compatibility with future Airflow releases.

41391Kaxil Naik 
Deprecated airflow.sensors.external_task.ExternalTaskSensorLink YNNNNNNThe airflow.sensors.external_task.ExternalTaskSensorLink class has been removed. This class was deprecated and is no longer available. Users should now use the airflow.sensors.external_task.ExternalDagLink class directly.
41393Kaxil Naik 
Deprecated use_task_execution_day parameter in DayOfWeekSensor YNNNNNNThe use_task_execution_day parameter has been removed from the DayOfWeekSensor class. This parameter was previously deprecated in favor of use_task_logical_date.
If your code still uses use_task_execution_day, you should update it to use use_task_logical_date instead to ensure compatibility with future Airflow versions.
Example update:
sensor = DayOfWeekSensor(
task_id="example",
week_day="Tuesday",
use_task_logical_date=True,
dag=dag,
)

41394Kaxil Naik 
Deprecated airflow.models.taskMixin.TaskMixinYNNNNNNThe airflow.models.taskMixin.TaskMixin class has been removed. It was previously deprecated in favor of the airflow.models.taskMixin.DependencyMixin class. If your code relies on TaskMixin, please update it to use DependencyMixin instead to ensure compatibility with Airflow 3.0 and beyond.
41395
Deprecated airflow.utils functions, constants, classesYNNNNNNThe following deprecated functions, constants, and classes have been removed as part of Airflow 3.0:
airflow.executors.executor_loader.UNPICKLEABLE_EXECUTORS: No direct replacement; this constant is no longer needed.

airflow.utils.dag_cycle_tester.test_cycle function: Use airflow.utils.dag_cycle_tester.check_cycle instead.
airflow.utils.file.TemporaryDirectory function: Use tempfile.TemporaryDirectory instead.
airflow.utils.file.mkdirs function: Use pathlib.Path.mkdir instead.
airflow.utils.state.SHUTDOWN state: No action needed; this state is no longer used.
airflow.utils.state.terminating_states constant: No action needed; this constant is no longer used

41420
Replaced Python's list with MutableSet for the property DAG.tags.N?NNNNNNReplaced Python's list with MutableSet for the property DAG.tags.

At the constractur you still can use list, you actually can use any data structure that implements the Collection interface.

The tags property of the DAG model would be of type MutableSet instead of list, as there are no actual duplicates at the tags.

41434
Experimental API removedNNYNNNNDeprecated Experimental API is no longer available in Airflow. Users should transition to using Rest API as an alternative.
41440
Deprecated and unused methods / properties on DAGYNNNNNNRemoved unused methods / properties in models/dag.py

Methods removed:

set_dag_runs_state
bulk_sync_to_db

41453
Legacy DAG Schedule args removedYNYNYNNRemoved legacy scheduling arguments on DAG
The schedule_interval and timetable arguments are removed from DAG.
The schedule_interval _attribute_ has also been removed. In the API, a new timetable_summary field has been added to replace schedule_interval for presentation purposes.

Since the DAG object no longer has the schedule_interval attribute, OpenLineage facets that contain the dag key produced on Airflow 3.0 or later will also no longer contain the field.

41496
Deprecated methods in date utilsYNNNNNNRemoved deprecated methods in airflow/utils/dates.py

Methods removed:
date_range

41533
Deprecated load_connections paramYNNNNNNThe load_connections parameter has been removed from the local_file_system. This parameter was previously deprecated in favor of load_connections_dict.

If your code still uses load_connections, you should update it to use load_connections_dict instead to ensure compatibility with future Airflow versions.
Example update:
connection_by_conn_id = local_filesystem.load_connections_dict(file_path="a.json")
The get_connections parameter has been removed from the LocalFilesystemBackend class. This parameter was previously deprecated in favor of get_connection.

If your code still uses get_connections, you should update it to use get_connection instead to ensure compatibility with future Airflow versions.

Example update:
connection_by_conn_id = LocalFilesystemBackend().get_connection(conn_id="conn_id")

Refactor register_dataset_changesNNNNNNNNew function create_dataset_aliases added to DatasetManager for DatasetAlias creation.
DatasetManager.create_datasets now takes Dataset objects

This function previously accepts a list of DatasetModel objects. it now receives Dataset objects instead. A list of DatasetModel objects are created inside, and returned by the function.

Also, the session argument is now keyword-only.

42404
From logical_date to run_id in APIs and functionsNNYNYNNRemoved logical_date arguments from functions and APIs for DAG run lookups to align with Airflow 3.0.

The shift towards using run_id as the sole identifier for DAG runs eliminates the limitations of execution_date and logical_date, particularly for dynamic DAG runs and cases where multiple runs occur at the same logical time. This change impacts database models, templates, and functions:

Removed logical_date arguments from public APIs and Python functions related to DAG run lookups.
run_id is now the exclusive identifier for DAG runs in these contexts.

42436

Change default .airflowignore syntax to glob
NNNNYNNDefault .airflowignore syntax changed to glob

The default value to the configuration [core] dag_ignore_file_syntax has been changed to glob, which better matches the ignore file behavior of many popular tools.

43289
Remove ability to import executors from pluginsNNNNNYNSupport for adding executors via Airflow Plugins is removed

Executors should no longer be registered or imported via Airflow's plugin mechanism -- these types of classes are just treated as plain Python classes by Airflow, so there is no need to register them with Airflow
