• Jun 29, 2026 Observability kube-prometheus-stack-app v22.0.0

  Changed

  • Upgraded chart dependency to kube-prometheus-stack-87.3.0 (from 85.2.1)
    • prometheus-operator to 0.92.0 (via 0.91.0)
    • alertmanager image tag from v0.32.1 to v0.33.0
    • prometheus image tag from v3.11.3-distroless to v3.12.0-distroless
    • grafana subchart from 12.3.3 to 12.7.1
    • kube-state-metrics subchart from 7.4.0 to 7.5.1
    • kube-webhook-certgen image tag from 1.8.3 to 1.8.4
    • Refreshed bundled default Prometheus alerting/recording rules and Grafana dashboards.
    • prometheus.prometheusSpec.containers and initContainers are now rendered through tpl (87.3.0), so templated values inside them are evaluated. We do not set these values, so no impact.

  Note: Update the matching-major prometheus-operator-crd app (to the v0.92.0 CRDs) before/alongside this upgrade. The PrometheusTopologySharding and PrometheusShardRetentionPolicy feature gates are now enabled by default in v0.92.0.

  Changed

  • Upgrade Alloy upstream chart from 1.8.2 to 1.10.0 (CHANGELOG)

    • Adds opt-in controller.autoscaling.horizontal.externalHPA (externally-managed HPAs, e.g. KEDA) and service.externalTrafficPolicy values. Neither is enabled in our defaults.

• Jun 29, 2026 Observability observability-bundle v3.1.0

  Changed

  • HelmReleases: honor the App platform priority field (1-150, default 25) on extraConfigs entries. spec.valuesFrom now reproduces the App platform merge order — all configMaps before all secrets (a secret always overrides a configMap), each kind ordered by priority around the user-config layer — preserving the App CR merge semantics after the migration.
