3.0.102

May 28, 2026

What’s New

  • The Anypoint Runtime Manager UI now supports handlebar-style placeholders (such as {{ .ApplicationName }}) when configuring public endpoints for HTTP route templates. Runtime Manager replaces placeholders that you enter in host or path fields with deployment-specific values at deployment time. The Runtime Manager UI now treats legacy ingress-style strings such as app-name as literal strings, not as placeholders, for HTTP route templates.

  • Supported keys for pod.env field in the Anypoint Controller

    When deploying Mule applications using the Anypoint Controller CR (MuleApplication), the pod.env field in the CR spec supports only these keys:

    • ENABLE_CONSOLE_LOG: Enables console logging for the application container.

    • ENABLE_READINESS_PROBE_ON_HTTP_GET: Enables the native Kubernetes HTTP GET readiness probe (requires Mule runtime patches from November 7, 2025 or later).

    • DISABLE_PER_APP_SA: Disables the per-application service account, causing the Mule application to use the default namespace service account.

      For further details, refer to Kubernetes Customization.

W-20921271

Runtime Fabric application initialization pods no longer fail with Error: checksum validation failed following a Runtime Fabric upgrade. The application init container now correctly detects corrupt or outdated cache artifacts and requests a new version from the upstream.

New or updated deployments automatically receive this fix with the latest Runtime Fabric version. Redeploy existing applications to use the updated init container image and resolve any persistent checksum errors.

  • 1.31.x

3.0.1

December 8, 2025

What’s New

  • Runtime Fabric agent version 3.0.1 now supports Anypoint Controller for Kubernetes. This operator enables you to deploy and manage Mule applications on Runtime Fabric using GitOps workflows and Custom Resources (CR).

  • Runtime Fabric agent version 3.0.1 now supports Mule app restart. You can restart applications to resolve runtime issues such as memory leaks or unresponsive services without redeploying. All restart activities are tracked in the Access Management audit log.

  • Runtime Fabric agent version 3.0.1 removes support for the legacy DaemonSet-based log forwarding method. Application logs are now forwarded exclusively through sidecar containers deployed alongside each application replica, providing better isolation and improved resource management.

  • When using Runtime Fabric 3.0.1 or later, the HTTP GET readiness probe configuration (which defaults to false) requires your applications to run on Mule runtime engine patches from November 7, 2025, or later. If this feature is enabled for applications on older patches, they may fail to become ready or restart correctly. If you can’t upgrade your runtimes immediately, make sure the feature remains disabled. For details, refer to Readiness Probe.
