Significant Changes

• Users who only have read access to DAGs will no longer be able to fetch data from the /dags endpoint, as it now requires additional permissions (DagAccessEntity.RUN, DagAccessEntity.HITL_DETAIL, and DagAccessEntity.TASK_INSTANCE). This change was made because the endpoint returns aggregated data from these multiple entities. Please update your custom user roles to include read access for DAG Runs, Task Instances, and HITL Details if those users should still have access to the /dags endpoint. (#64822)

Apache Airflow 3.2.0

📦 PyPI: https://pypi.org/project/apache-airflow/3.2.0/
📚 Docs: https://airflow.apache.org/docs/apache-airflow/3.2.0/
🛠 Release Notes: https://airflow.apache.org/docs/apache-airflow/3.2.0/release_notes.html

🚏 Constraints: https://github.com/apache/airflow/tree/constraints-3.2.0

Significant Changes

Asset Partitioning

The headline feature of Airflow 3.2.0 is asset partitioning — a major evolution of data-aware
scheduling. Instead of triggering Dags based on an entire asset, you can now schedule downstream
processing based on specific partitions of data. Only the relevant slice of data triggers downstream
work, making pipeline orchestration far more efficient and precise.

This matters when working with partitioned data lakes — date-partitioned S3 paths, Hive table
partitions, BigQuery table partitions, or any other partitioned data store. Previously, any update
to an asset triggered all downstream Dags regardless of which partition changed. Now only the right
work gets triggered at the right time.

For detailed usage instructions, see :doc:/authoring-and-scheduling/assets.

Multi-Team Deployments

Airflow 3.2 introduces multi-team support, allowing organizations to run multiple isolated teams within a single Airflow deployment.
Each team can have its own Dags, connections, variables, pools, and executors— enabling true resource and permission isolation without requiring separate Airflow instances per team.

This is particularly valuable for platform teams that serve multiple data engineering or data science teams from shared infrastructure, while maintaining strong boundaries between teams' resources and access.

For detailed usage instructions, see :doc:/core-concepts/multi-team.

.. warning::

Multi-Team Deployments are experimental in 3.2.0 and may change in future versions based on
user feedback.

Synchronous callback support for Deadline Alerts

Deadline Alerts now support synchronous callbacks via SyncCallback in addition to the existing
asynchronous AsyncCallback. Synchronous callbacks are executed by the executor (rather than
the triggerer), and can optionally target a specific executor via the executor parameter.

A Dag can also define multiple Deadline Alerts by passing a list to the deadline parameter,
and each alert can use either callback type.

.. warning::

Deadline Alerts are experimental in 3.2.0 and may change in future versions based on
user feedback. Synchronous deadline callbacks (SyncCallback) do not currently
support Connections stored in the Airflow metadata database.

For detailed usage instructions, see :doc:/howto/deadline-alerts.

UI Enhancements & Performance

• Grid View Virtualization:
  The Grid view now uses virtualization -- only visible rows are rendered to the DOM. This dramatically improves performance when viewing Dags with large numbers of task runs, reducing render time and memory usage for complex Dags. (#60241)

• XCom Management in the UI:
  You can now add, edit, and delete XCom values directly from the Airflow UI. This makes it much easier to debug and manage XCom state during development and day-to-day operations without needing CLI commands. (#58921)

• HITL Detail History:
  The Human-in-the-Loop approval interface now includes a full history view, letting operators and reviewers see the complete audit trail of approvals and rejections for any task. (#56760, #55952)

• Gantt Chart Improvements:

  • All task tries displayed: Gantt chart now shows every attempt, not just the latest
  • Task display names in Gantt: task_display_name shown for better readability (#61438)
  • ISO dates in Gantt: Cross-browser consistent date format (#61250)
  • Fixed null datetime crash: Gantt chart no longer crashes on tasks with null datetime fields

New --only-idle flag for the scheduler CLI

The airflow scheduler command has a new --only-idle flag that only counts runs when the
scheduler is idle. This helps users run the scheduler once and process all triggered Dags and
queued tasks. It requires and complements the --num-runs flag so one can set a small value
instead of guessing how many iterations the scheduler needs.

Replace per-run TI summary requests with a single NDJSON stream

The grid, graph, gantt, and task-detail views now fetch task-instance
summaries through a single streaming HTTP request
(GET /ui/grid/ti_summaries/{dag_id}?run_ids=...) instead of one request
per run. The server emits one JSON line per run as soon as that run's task
instances are ready, so columns appear progressively rather than all at once.

What changed:

• GET /ui/grid/ti_summaries/{dag_id}?run_ids=... is now the sole endpoint
  for TI summaries, returning an application/x-ndjson stream where each
  line is a serialized GridTISummaries object for one run.
• The old single-run endpoint GET /ui/grid/ti_summaries/{dag_id}/{run_id}
  has been removed.
• The serialized Dag structure is loaded once and shared across all runs that
  share the same dag_version_id, avoiding redundant deserialization.
• All UI views (grid, graph, gantt, task instance, mapped task instance, group
  task instance) use the stream endpoint, passing one or more run_ids.

Structured JSON logging for all API server output

The new json_logs option under the [logging] section makes Airflow
produce all its output as newline-delimited JSON (structured logs) instead of
human-readable formatted logs. This covers the API server (gunicorn/uvicorn),
including access logs, warnings, and unhandled exceptions.

Not all components support this yet — notably airflow celery worker but
any non-JSON output when json_logs is enabled will be treated as a bug. (#63365)

Remove legacy OTel Trace metaclass and shared tracer wrappers

The interfaces and functions located in airflow.traces were
internal code that provided a standard way to manage spans in
internal Airflow code. They were not intended as user-facing code
and were never documented. They are no longer needed so we
remove them in 3.2. (#63452)

Move task-level exception imports into the Task SDK

Airflow now sources task-facing exceptions (AirflowSkipException, TaskDeferred, etc.) from
airflow.sdk.exceptions. airflow.exceptions still exposes the same exceptions, but they are
proxies that emit DeprecatedImportWarning so Dag authors can migrate before the shim is removed.

What changed:

• Runtime code now consistently raises the SDK versions of task-level exceptions.
• The Task SDK redefines these classes so workers no longer depend on airflow-core at runtime.
• airflow.providers.common.compat.sdk centralizes compatibility imports for providers.

Behaviour changes:

• Sensors and other helpers that validate user input now raise ValueError (instead of
  AirflowException) when poke_interval/ timeout arguments are invalid.
• Importing deprecated exception names from airflow.exceptions logs a warning directing users to
  the SDK import path.

Exceptions now provided by airflow.sdk.exceptions:

• AirflowException and AirflowNotFoundException
• AirflowRescheduleException and AirflowSensorTimeout
• AirflowSkipException, AirflowFailException, AirflowTaskTimeout, AirflowTaskTerminated
• TaskDeferred, TaskDeferralTimeout, TaskDeferralError
• DagRunTriggerException and DownstreamTasksSkipped
• AirflowDagCycleException and AirflowInactiveAssetInInletOrOutletException
• ParamValidationError, DuplicateTaskIdFound, TaskAlreadyInTaskGroup, TaskNotFound, XComNotFound
• AirflowOptionalProviderFeatureException

Backward compatibility:

• Existing Dags/operators that still import from airflow.exceptions continue to work, though
  they log warnings.
• Providers can rely on airflow.providers.common.compat.sdk to keep one import path that works
  across supported Airflow versions.

Migration:

• Update custom operators, sensors, and extensions to import exception classes from
  airflow.sdk.exceptions (or from the provider compat shim).
• Adjust custom validation code to expect ValueError for invalid sensor arguments if it
  previously caught AirflowException.

Support numeric multiplier values for retry_exponential_backoff parameter

The retry_exponential_backoff parameter now accepts numeric values to specify custom exponential backoff multipliers for task retries. Previously, this parameter only accepted boolean values (True or False), with True using a hardcoded multiplier of 2.0.

New behavior:

• Numeric values (e.g., 2.0, 3.5) directly specify the exponential backoff multiplier
• retry_exponential_backoff=2.0 doubles the delay between each retry attempt
• retry_exponential_backoff=0 or False disables exponential backoff (uses fixed retry_delay)

Backwards compatibility:

Existing Dags using boolean values continue to work:

• retry_exponential_backoff=True → converted to 2.0 (maintains original behavior)
• retry_exponential_backoff=False → converted to 0.0 (no exponential backoff)

API changes:

The REST API schema for retry_exponential_backoff has changed from type: boolean to type: number. API clients must use numeric values (boolean values will be rejected).

Migration:

While boolean values in Python Dags are automatically converted for backwards compatibility, we recommend updating to explicit numeric values for clarity:

• Change retry_exponential_backoff=True → retry_exponential_backoff=2.0
• Change ``retry_exponential_backoff=False...

Apache Airflow Helm Chart 1.20.0

Significant Changes

Support for old versions of Apache Airflow <2.11 has been dropped (#61018)

Minimum supported version of Apache Airflow is now 2.11.0. If you want to deploy an
old version of Apache Airflow, please use the last released version of the chart 1.19.0.

workers specific sections have been moved to workers.celery / workers.kubernetes sections

Please update your configuration accordingly:

• workers.command command is now deprecated in favor of workers.celery.command/workers.kubernetes.command (#60067).
• workers.securityContexts command is now deprecated in favor of workers.celery.securityContexts/workers.kubernetes.securityContexts (#60396).
• workers.containerLifecycleHooks command is now deprecated in favor of workers.celery.containerLifecycleHooks/workers.kubernetes.containerLifecycleHooks (#61369).
• workers.kerberosSidecar section is now deprecated in favor of workers.celery.kerberosSidecar/workers.kubernetes.kerberosSidecar (#61881).
• workers.kerberosInitContainer section is now deprecated in favor of workers.celery.kerberosInitContainer/workers.kubernetes.kerberosInitContainer (#60751).
• workers.terminationGracePeriodSeconds command is now deprecated in favor of workers.celery.terminationGracePeriodSeconds/workers.kubernetes.terminationGracePeriodSeconds (#61892).
• workers.nodeSelector command is now deprecated in favor of workers.celery.nodeSelector/workers.kubernetes.nodeSelector (#61957).
• workers.podDisruptionBudget section is now deprecated in favor of workers.celery.podDisruptionBudget. Please update your configuration accordingly. (#61414)
• workers.keda section is now deprecated in favor of workers.celery.keda. Please update your configuration accordingly. (#61820)
• workers.resources section is now deprecated in favor of workers.celery.resources and workers.kubernetes.resources. Please update your configuration accordingly. (#61890)

The previous configuration options are still working, but are deprecated and will be removed in a future version.

As Git-Sync is not service-type object, the readiness probe will be removed. (#62334)

To enable feature behaviour set dags.gitSync.recommendedProbeSetting to true. Section itself will be removed in future release as to not break setups during upgrades.

As Git-Sync has dedicated liveness service, the liveness probe behaviour will be changed. To enable feature behaviour set dags.gitSync.recommendedProbeSetting to true.

Please update your configuration accordingly.

Automatic env variables removed from container_extra_envs and custom_airflow_environment (#60750)

The automatic prefix addition for Kubernetes Executor environment variables and secrets has been removed from both the container_extra_envs and custom_airflow_environment helper functions.

What changed:

Previously, when you added environment variables to component-specific configurations (e.g., .Values.scheduler.env), the chart automatically created an additional environment variable (to specified in the env section) with the AIRFLOW__KUBERNETES_ENVIRONMENT_VARIABLES__ prefix for Kubernetes Executor worker pods. After this change, only the variable specified in env section will be created.
Furthermore, for values specified under .Values.secret section, the AIRFLOW__KUBERNETES_SECRETS__ prefix is no longer automatically added. Secrets are now passed as-is via secretKeyRef without the prefixed copy for worker pods.

Why this change:

• Prevent unintended exposure of sensitive data like client_secret information. Previously, due to prefix, it was recognized as internal Airflow configuration leading to unintended exposure in Airflow UI (under Admin -> Configuration), even when AIRFLOW__API__EXPOSE_CONFIG is set to non-sensitive-only.
• Avoid unintended environment propagation to workers: component-specific env configurations are intended strictly for specific components. Previous behaviour caused these variables to be passed to worker pods, which could result in configuration conflicts and unexpected side effects.

Migration Required:

If you need to pass environment variables specifically to Kubernetes Executor worker pods, use one of the following approaches:

Option 1: Use .Values.env

.. code-block:: yaml

env:
  - name: my_var
    value: "my_value"

Environment variables specified under .Values.env are now passed as-is without the automatic prefix (same behaviour as component-specific env).

Option 2: Use .Values.config.kubernetes_environment_variables

.. code-block:: yaml

config:
  kubernetes_environment_variables:
    my_var: "my_value"

Significant Changes

Backfill permissions are now handled via DagAccessEntity.Run (#61456)

is_authorized_backfill of the BaseAuthManager interface has been removed. Core will no longer call this method and their
provider counterpart implementation will be marked as deprecated.
Permissions for backfill operations are now checked against the DagAccessEntity.Run permission using the existing
requires_access_dag decorator. In other words, if a user has permission to run a DAG, they can perform backfill operations on it.

Please update your security policies to ensure that users who need to perform backfill operations have the appropriate DagAccessEntity.Run permissions. (Users
having the Backfill permissions without having the DagRun ones will no longer be able to perform backfill operations without any update)

Apache Airflow Helm Chart 1.19.0

Significant Changes

StatsD metrics aggregation now supports configurable TTL-enabled LRU cache to prevent memory growth in long-running daemons (#60933)

The Helm Chart now includes new configuration options for StatsD aggregation management:

• statsd.cache.type - Enable TTL-enabled lru cache or random cache for metrics aggregation (default: lru)
• statsd.cache.size - Maximum number of metrics to cache (default: 1000)
• statsd.cache.ttl - Time-to-live for cached metrics in seconds (0s is TTL disabled) (default: 0s)

This feature addresses uncontrolled memory growth in StatsD daemons by automatically cleaning up stale or unused metric entries. When enabled, the cache uses both LRU (Least Recently Used) eviction and TTL (Time To Live) expiration to manage memory usage effectively.

To maintain backward compatibility, the default behaviour remains unchanged. Users experiencing memory growth issues with StatsD can enable this feature by setting statsd.cache.ttl to value higher than 0 in their Helm values.

Support for Multiple Celery Worker Sets in the Helm Chart (#58547)

This change introduces support for advanced Celery Workers topologies to Apache Airflow Helm Chart, enabling more flexible resource allocation and precise autoscaling configurations.

Flexible Worker Topologies: The new workers.celery.enableDefault flag allows users to configure a deployment consisting only of specialized worker sets defined in workers.celery.sets section.

Multi-Queue Autoscaling Support: Updates the KEDA ScaledObject generation to support comma-separated queue lists. By using the SQL IN (...) clause, we ensure that KEDA scales worker sets based on the precise aggregate workload of all their assigned queues.

Granular Configuration Overrides: This change allows for overwrite of any currently available workers configuration per worker set. For example, a user can enable KEDA globally, but explicitly disable it for a specific worker set that requires a static number of replicas.

Options to create a default user have been moved under the createUserJob section

Please update your configuration accordingly:

• webserver.defaultUser section is now deprecated in favor of createUserJob (#59767)

The previous configuration options are still working but are deprecated and will be removed in a future version.

Note that the previous documentation described also the option apiServer.defaultUser, which was never implemented in the chart. The only supported option is now createUserJob. Using apiServer.defaultUser will raise an error.

Celery specific config options have been moved under the celery section in workers

Please update your configuration accordingly:

• workers.replicas command is now deprecated in favor of workers.celery.replicas (#59730)
• workers.revisionHistoryLimit command is now deprecated in favor of workers.celery.revisionHistoryLimit (#60056)
• workers.args command is now deprecated in favor of workers.celery.args (#60163)
• workers.livenessProbe section is now deprecated in favor of workers.celery.livenessProbe (#60186)
• workers.updateStrategy section is now deprecated in favor of workers.celery.updateStrategy (#60351)
• workers.strategy section is now deprecated in favor of workers.celery.strategy (#60354)
• workers.podManagementPolicy section is now deprecated in favor of workers.celery.podManagementPolicy (#60359)
• workers.persistence section is now deprecated in favor of workers.celery.persistence (#60238)

The previous configuration options are still working but are deprecated and will be removed in a future version.

Manual Service Account Token Volume configuration for pod-launching executors (#59156)

Added support for manual Service Account Token Volume configuration when using pod-launching executors
(CeleryExecutor, CeleryKubernetesExecutor, KubernetesExecutor, LocalKubernetesExecutor).
This implements defense-in-depth security with both ServiceAccount and Pod-level controls, providing
compatibility with security policies like Kyverno and enabling container-specific privilege assignment
following the Principle of Least Privilege.

Add imagePullSecrets option (#58094)

Add .Values.imagePullSecrets as the new mechanism for configuring registry credentials,
deprecating both .Values.registry.secretName and the automatic creation of the <RELEASE_NAME>-registry secret from .Values.registry.connection.

Default Airflow image is updated to 3.1.7 (#61447)

The default Airflow image that is used with the Chart is now 3.1.7, previously it was 3.0.2.

Default git-sync image is updated to 4.4.2 (#54085)

The default git-sync image that is used with the Chart is now 4.4.2, previously it was 4.3.0.
