Redis Radar release notes 2026.11.1

High-availability status, agent health, password changes and resets, and HTTPS on the API server.

Redis Radar

Redis Radar 2026.11.1 shows high-availability status in the Databases list and agent health in Settings > Agents. It lets local users change and reset their passwords, lets the API server serve HTTPS, and fixes gaps in agent and Redis Cloud collection.

This is a Short-Term Support (STS) release. See Self-managed releases for more details.

Enhancements

  • High-availability status. The Databases list now shows the high-availability status of each Redis Software database, and a High availability summary card counts the databases without it.

  • Agent health. Settings > Agents now shows warnings for each agent and the collection status of each of its sources.

  • Change your password. Local users can change their own password from Change password in the user menu. Changing it signs you out of your other sessions. See Change or reset a local password.

  • Reset a local user's password. Operators with access to the Radar host or cluster can reset a local user's password with radar user reset-password --user <username-or-email>. The command prompts for the new password, or reads it from standard input with --password-stdin. It also clears a lockout and ends the user's sessions. See Change or reset a local password.

  • HTTPS on the API server. The API server can now serve HTTPS itself, so traffic stays encrypted up to the process. It's off by default.

    • Helm: set app.tls.enabled to true and app.tls.existingSecret to a kubernetes.io/tls Secret in the release namespace. If an Ingress is in front of Radar, set ingress.backendTLS to your Ingress controller. You can't combine this with the OpenShift Route. See Install on Kubernetes with Helm.
    • RPM: set HTTP_TLS_CERT_FILE and HTTP_TLS_KEY_FILE. See Install on RHEL with the RPM.

    Restart the API server after you rotate the certificate.

  • LDAP sign-in failures. Settings > Security now lists recent LDAP sign-in failures.

  • Packaged documentation. Updated the documentation packaged with the Helm chart and the RPM.

  • Dependencies. Updated Go to 1.26.10 to fix CVE-2026-111943 (GO-2026-6809), and updated other dependencies.

Resolved issues

  • Edited managed-agent sources. A managed agent no longer stops collecting after you edit one of its sources. If you edited a source before you upgrade, save it again.
  • Managed agents with no sources. A managed agent with no sources no longer fails its heartbeat.
  • Agent source failures. A failed source no longer marks the other sources of its agent as failed.
  • Interrupted collections. Redis Open Source and Redis Cloud connections no longer stop collecting when a worker stops during a collection.
  • Redis Cloud collection timeouts. Redis Cloud collections no longer fail after 1 minute.
  • Removed cluster resources. Nodes, shards, alerts, and database health no longer stay in Radar after a Redis Software cluster stops reporting them.
  • Active-Active summary through an agent. Redis Software clusters connected through an agent now show their Active-Active summary.
  • Redis Open Source through an agent. Redis Open Source sources connected through an agent now show their connection and databases.
  • Redis Cloud endpoints. Radar now collects from a Redis Open Source connection that points to a Redis Cloud database endpoint.

Breaking changes

  • Audit retention limit. AUDIT_RETENTION_DAYS now accepts at most 36500. If the value is larger, Radar doesn't start. Change it before you upgrade.
  • HTTPS backend-protocol annotations. Helm now rejects an Ingress or Service annotation that sets an HTTPS backend protocol while app.tls.enabled is false. Remove the annotation before you upgrade, or enable HTTPS on the API server.
