Release notes for version 0.85.6

Release date: 26 Jun 2026

• sync-job supports manifest generation mode: set OUTPUT=- (stdout) or OUTPUT=<file> to write all rendered ConfigMap/GrafanaDashboard/VMRule manifests as YAML instead of applying them to the cluster, allowing users to commit the output to a repository and deploy via GitOps tools in air-gapped environments. See #3040
• fix sync-job not injecting hidden constant $cluster variable into dashboards that have no cluster template variable, causing Grafana to show "No data" or variable errors when multicluster: false. See #3042
