End user facing changes

🛑 Breaking changes 🛑

  • receiver/kubeletstats: Fixes a bug where the "insecure_skip_verify" config was not being honored when "auth_type" is "serviceAccount" in kubelet client. (#26319)
    Before the fix, the kubelet client was not verifying kubelet's certificate. The default value of the config is false,
    so with the fix the client will start verifying tls cert unless the config is explicitly set to true.

  • parquetexporter: Deprecate the Parquet Exporter, it will be removed in the next release. (#27284)

  • bug_fix: Improve counting for the count_traces_sampled metric (#25882)

  • extension/filestorage: Replace path-unsafe characters in component names (#3148)

🚩 Deprecations 🚩

  • resourcedetectionprocessor: Detect faas.instance in the gcp detector, and deprecate detecting faas.id in the gcp detector. (#26486)
    faas.id has been removed from the semantic conventions.
  • k8sclusterreceiver: Deprecate opencensus.resourcetype resource attribute (#26487)
    opencensus.resourcetype resource attribute is deprecated and disabled by default.

🚀 New components 🚀

  • encodingextension: Add implementation of encodingextension (#6272)

💡 Enhancements 💡

  • processor/probabilisticsampler: Allow non-bytes values to be used as the source for the sampling decision (#18222)
  • receiver/azuremonitorreceiver: Add support for authenticating using AD workload identity (#24451)
  • kafkareceiver: Allow users to attach kafka header metadata with the log/metric/trace record in the pipeline. Introduce a new config param, 'header_extraction' and some examples. (#24367)
  • exporter/kafkaexporter: Adding Zipkin encoding option for traces to kafkaexporter (#21102)
  • kubeletstatsreceiver: Support specifying context for kubeConfig auth_type (#26665)
  • kubeletstatsreceiver: Adds new k8s.pod.cpu_limit_utilization, k8s.pod.cpu_request_utilization, k8s.container.cpu_limit_utilization, and k8s.container.cpu_request_utilization metrics that represent the ratio of cpu used vs set limits and requests. (#27276)
  • kubeletstatsreceiver: Adds new k8s.pod.memory_limit_utilization, k8s.pod.memory_request_utilization, k8s.container.memory_limit_utilization, and k8s.container.memory_request_utilization metrics that represent the ratio of memory used vs set limits and requests. (#25894)
  • filestatsreceiver: Move the filestats receiver to beta stability (#27252)
  • haproxyreceiver: Move the haproxyreceiver to beta stability (#27254)
  • splunkentreceiver: adding additional metrics to the splunkentreceiver (#12667)
  • cmd/telemetrygen: Add support for custom telemetry attributes (#26505)

🧰 Bug fixes 🧰

  • processor/spanmetrics: Prune histograms when dimension cache is pruned. (#27080)
    Dimension cache was always pruned but histograms were not being pruned. This caused metric series created
    by processor/spanmetrics to grow unbounded.

  • syslogexporter: use proper defaults according to RFCs (#25114)

  • syslogparser: return correct structure from syslog parser (#27414)

  • splunkhecreceiver: Fix receiver behavior when used for metrics and logs at the same time; metrics are no longer dropped. (#27473)

  • metricstransformprocessor: Fixes a nil pointer dereference when copying an exponential histogram (#27409)

  • telemetrygen: better defaults for http exporter mode (#26999)

    • the url path default is now correct for both traces and metrics
    • when not provided, the endpoint is automatically set to target a local gRPC or HTTP endpoint depending on the communication mode selected

  • k8sclusterreceiver: change k8s.container.ready, k8s.pod.phase, k8s.pod.status_reason, k8s.namespace.phase units to empty (#10553)

  • k8sclusterreceiver: Change k8s.node.condition* metric units to empty (#10553)

  • syslogreceiver: Fix issue where long tokens would be truncated prematurely (#27294)

  • mongodbreceiver: Fix mongo version not being collected (#27441)

  • pulsarexporter: Do not export function WithTracesMarshalers, add test for that and pass checkapi (#26304)
  • pulsarreceiver: Do not export the functions WithLogsUnmarshalers, WithMetricsUnmarshalers, WithTracesUnmarshalers, add tests and pass checkapi. (#26304)

💡 Enhancements 💡

  • mdatagen: allows adding warning section to resource_attribute configuration (#19174)
