# Remote Execution Agent Helm chart release notes

> A changelog of changes to the Astro Remote Execution Agent Helm chart, by chart version.

<Note> This is feature is only available if you are on the **Enterprise** tier or above. See [Astro Plans and Pricing](https://www.astronomer.io/pricing/).</Note>

This page lists changes to the Astro Remote Execution Agent Helm chart. The Helm chart has its own version, separate from the Remote Execution Agent version that it deploys by default. See [Helm chart versioning](/docs/astro/agent-maintenance-policy#helm-chart-versioning) for how the two relate, and the [Helm chart to Astro agent compatibility matrix](/docs/astro/agent-maintenance-policy#helm-chart-to-astro-agent-compatibility-matrix) for which combinations Astronomer supports.

For changes to the Remote Execution Agent itself, see [Remote Execution Agent release notes](/docs/astro/agent-release-notes). For the full list of configurable values, see [Helm chart configuration reference](/docs/astro/remote-agents-helm-reference).

<Update label="Helm chart 2.3.3" description="July 22, 2026">
  * **Fixed:** The chart no longer overrides image entrypoints. For the default agent images this ensures that orphaned processes in agent containers are correctly reaped by the init process.
</Update>

<Update label="Helm chart 2.3.2" description="July 17, 2026">
  * **Changed:** Default `appVersion` updated to Remote Execution Agent 1.8.2.
</Update>

<Update label="Helm chart 2.3.1" description="July 15, 2026">
  * **Changed:** Default `appVersion` updated to Remote Execution Agent 1.8.1, which added Airflow 3.3 support.
</Update>

<Update label="Helm chart 2.3.0" description="July 7, 2026">
  * **Added:** A `stateStoreBackend` value, alongside the existing `xcomBackend` and `secretBackend` values, to configure the Airflow 3.3+ worker-side state store backend. See [Configure state store backend](/docs/astro/remote-execution-configure-state-store-backend).
</Update>

<Update label="Helm chart 2.2.2" description="July 1, 2026">
  * **Changed:** Default `appVersion` updated to Remote Execution Agent 1.7.2.
</Update>

<Update label="Helm chart 2.2.1" description="June 17, 2026">
  * **Fixed:** 2.2.0 broke `helm install`/`helm template` when the newly-added OpenLineage configuration wasn't provided explicitly in `values.yaml`. Fixed in this release.
</Update>

<Update label="Helm chart 2.2.0" description="June 17, 2026">
  * **Added:** Extended OpenLineage configuration options: `openLineage.endpoint` and `openLineage.facetsEnvironmentVariables`. See [Configure OpenLineage](/docs/astro/remote-execution-configure-openlineage).
</Update>

<Update label="Helm chart 2.1.0" description="June 4, 2026">
  * **Added:** The chart now attempts to validate that configured agent image tags meet the minimum supported Astro Agent version. See the [compatibility matrix](/docs/astro/agent-maintenance-policy#helm-chart-to-astro-agent-compatibility-matrix).
  * **Added:** Sentinel RBAC now grants access to Kubernetes events, so Sentinel can surface event-based failure reasons, such as readiness probe failures, for unhealthy components.
  * **Added:** Agent containers now receive `ASTRO_AGENT_CLIENT_COMPONENT_NAME` and `ASTRO_AGENT_CLIENT_REVISION` environment variables, so each agent component can report its resolved configuration keyed to a specific component and rollout.
  * **Fixed:** Changed the chart's `kubeVersion` constraint from `>= 1.30.0` to `>= 1.30.0-0` so that Kubernetes server version strings with a pre-release suffix, such as those reported by some EKS clusters (for example, `1.35.4-eks-40737a8`), satisfy the constraint.
</Update>

<Update label="Helm chart 2.0.0" description="April 17, 2026">
  <Warning>
    **Breaking change: worker label selectors**

    Label selectors on worker Deployments and Services now include a per-worker label. Kubernetes label selectors are immutable, so an in-place `helm upgrade` from a 1.x chart to 2.0.0 fails. See [Breaking change in Helm chart 2.0.0](/docs/astro/agent-maintenance-policy#helm-chart-to-astro-agent-compatibility-matrix) for the required upgrade steps.
  </Warning>

  * **Changed:** `sentinel.enabled` is now `true` by default. Previously, Sentinel monitoring was disabled unless you explicitly opted in. Task-level metrics collection is also enabled by default. See [Enable Sentinel monitoring](/docs/astro/remote-agents-sentinel).
  * **Changed:** Label selectors on worker Deployments and Services now include a per-worker label. See the breaking change note for required upgrade steps.
  * **Added:** JSON schema validation for Helm values, covering required fields and field types.
  * **Added:** Support for a custom service account and annotations for each worker.
  * **Added:** RBAC permissions allowing workers to launch pods using the `KubernetesPodOperator`.
</Update>

<Update label="Helm chart 1.0.0 to 1.5.0" description="April 22, 2025 to March 24, 2026">
  These chart versions were released in lockstep with the Remote Execution Agent client of the same version number, before chart versioning was decoupled in Helm chart 2.0.0. See [Remote Execution Agent release notes](/docs/astro/agent-release-notes) for the agent changes released during this period.
