This is feature is only available if you are on the Enterprise tier or above. See Astro Plans and Pricing.
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 for how the two relate, and the 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. For the full list of configurable values, see Helm chart configuration reference.

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.
​
July 17, 2026
  • Changed: Default appVersion updated to Remote Execution Agent 1.8.2.
​
July 15, 2026
  • Changed: Default appVersion updated to Remote Execution Agent 1.8.1, which added Airflow 3.3 support.
​
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.
​
July 1, 2026
  • Changed: Default appVersion updated to Remote Execution Agent 1.7.2.
​
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.
​
June 17, 2026
  • Added: Extended OpenLineage configuration options: openLineage.endpoint and openLineage.facetsEnvironmentVariables. See Configure OpenLineage.
​
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.
  • 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.

Breaking change: worker label selectorsLabel 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 for the required upgrade steps.
  • 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.
  • 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.

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 for the agent changes released during this period.
