This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.148.0.

💡 Enhancements 💡

• clusterReceiver: Add feature gate to send Kubernetes entities to Splunk Observability v3/event endpoint (#2284)
  When enabled via featureGates.enableK8sEntities, the cluster receiver routes
  Kubernetes entity data (from the k8s_cluster receiver) to the Splunk Observability
  /v3/event endpoint via otlphttp. Requires Splunk Observability configuration.
  This feature is experimental and may change or be removed in future releases.
• operator: Bump java to v2.26.1 in helm-charts/splunk-otel-collector/values.yaml (#2299)
• operator: Bump nodejs to v4.4.0 in helm-charts/splunk-otel-collector/values.yaml (#2276)

🧰 Bug fixes 🧰

• config: Updated default configuration to use dot-notation attributes for internal metrics,
  addressing the upstream change in (#14815)
• agent: Add configurable scrapeInterval for control plane Prometheus receivers and default to 10s (#2302)
  The Prometheus receivers that replaced SmartAgent receivers for control plane components
  (apiserver, controller-manager, scheduler, proxy, coredns, etcd) were using the Prometheus
  default scrape interval of 60s instead of the SmartAgent default of 10s. A new
  agent.controlPlaneMetrics.scrapeInterval config option has been added (default: 10s)
  to allow users to tune the interval. This also applies to the EKS apiserver metrics
  collected by the cluster receiver.
• operator: Fix instrumentation hook job ServiceAccount missing imagePullSecrets from image.imagePullSecrets (#2321)
  When instrumentation.installationJob.enabled=true and image.imagePullSecrets is set,
  the dedicated ServiceAccount created for the hook job now receives the pull secrets,
  allowing the job's kubectl image to be pulled from a private registry.
