+Airflow Helm Chart 1.19.0 (2026-02-02)
+--------------------------------------
+
+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.
+
+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 ``3.1.6`` (#60453)
+""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+The default Airflow image that is used with the Chart is now ``3.1.6``,
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``.

-StatsD metrics aggregation now supports configurable TTL-enabled LRU cache to
prevent memory growth in long-running daemons.
-
-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
-
-Description
-The change introduces support for advanced Celery Workers topologies to Apache
Airflow Helm Chart, enabling more flexible resource allocation and precise
autoscaling configurations.
-
-Why is this needed?
-1. Flexible Worker Topologies
-As Airflow adoption grows, platform teams often need to route tasks
exclusively to specialized worker sets (e.g., GPU-optimized, Memory-optimized)
without maintaining a generic ``default`` worker.
-
-Enhancement: The new ``workers.celery.enableDefault`` flag allows users to
configure a deployment consisting only of specialized worker sets defined in
``workers.celery.sets`` section. This provides flexibility for teams to design
their workers architecture exactly as needed.
-2. Multi-Queue Autoscaling Support
-Complex workflows often require a single worker set to handle tasks from
multiple specific queues (e.g., queue: "high-priority,vip").
-
-Enhancement: This PR 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.
-3. Granular Configuration Overrides
-Different worker sets may require different operational strategies within the
same cluster.
-
-Enhancement: 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.
-Changes
-New Feature: Added ``workers.celery.enableDefault`` (default: true) to
values.yaml.
-
-See `Helm PR #58547 <https://github.com/apache/airflow/pull/58547>`_ and
`Helm PR #60420 <https://github.com/apache/airflow/pull/60420>`_ for
implementation details.

-(``CeleryExecutor``, ``CeleryKubernetesExecutor``, ``KubernetesExecutor``,

-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
