User facing changes

🛑 Breaking changes 🛑

• k8sclusterreceiver: Remove deprecated Kubernetes API resources (#23612, #26551)
  Drop support of HorizontalPodAutoscaler v2beta2 version and CronJob v1beta1 version.
  Note that metrics for those resources will not be emitted anymore on Kubernetes 1.22 and older.

• prometheusexporters: Append prometheus type and unit suffixes by default in prometheus exporters. (#26488)
  Suffixes can be disabled by setting add_metric_suffixes to false on the exporter.

• attributesprocessor, resourceprocessor: Transition featuregate coreinternal.attraction.hash.sha256 to stable (#4759)

💡 Enhancements 💡

• postgresqlreceiver: Added postgresql.database.locks metric. (#26317)

• receiver/statsdreceiver: Add support for distribution type metrics in the statsdreceiver. (#24768)

• pkg/ottl: Add converters to convert time to unix nanoseconds, unix microseconds, unix milliseconds or unix seconds (#24686)

• oauth2clientauthextension: Enable dynamically reading ClientID and ClientSecret from files (#26117)

  • Read the client ID and/or secret from a file by specifying the file path to the ClientIDFile (client_id_file) and ClientSecretFile (client_secret_file) fields respectively.
  • The file is read every time the client issues a new token. This means that the corresponding value can change dynamically during the execution by modifying the file contents.

• receiver/hostmetrics: Don't collect connections data from the host if system.network.connections metric is disabled to not waste CPU cycles. (#25815)

• jaegerreceiver,jaegerremotesamplingextension: Add featuregates to replace Thrift-gen with Proto-gen types for sampling strategies (#18401)
  Available featuregates are:

  • extension.jaegerremotesampling.replaceThriftWithProto
  • receiver.jaegerreceiver.replaceThriftWithProto

• influxdbexporter: Add user-configurable LogRecord dimensions (otel attributes -> InfluxDB tags) (#26342)

• k8sclusterreceiver: Add optional k8s.kubelet.version, k8s.kubeproxy.version node resource attributes (#24835)

• k8sclusterreceiver: Add k8s.pod.status_reason option metric (#24034)

• k8sobjectsreceiver: Adds logic to properly handle 410 response codes when watching. This improves the reliability of the receiver. (#26098)

• k8sobjectreceiver: Adds option to exclude event types (MODIFIED, DELETED, etc) in watch mode. (#26042)

• datadogexporter: Host metadata for remote hosts is now reported on first sight or on change (#25145)
  Host metadata for remote hosts will only be sent for payloads with the datadog.host.use_as_metadata resource attribute.

🧰 Bug fixes 🧰

• processor/routing: When using attributes instead of resource attributes, the routing processor would crash the collector. This does not affect the connector version of this component. (#26462)
• awsemfexporter: Fix possible panic in when configuration option awsemf.output_destination:stdout is set (#26250)
• snmpreceiver: Fix how to determine how many RAs on a metric are scalar (#26363)
  We now create the proper number of resources for configurations where a resource uses fewer than the available number of scalar resource attribtues.
• processor/tailsampling: Added saving instrumentation library information for tail-sampling (#13642)
• receiver/kubeletstats: Fixes client to refresh service account token when authenticating with kubelet (#26120)
• datadogexporter: Fixes crash when mapping OTLP Exponential Histograms with no buckets. These will now be dropped instead. (#26103)
• filelogreceiver: Fix the behavior of the add operator to continue to support EXPR(env("MY_ENV_VAR")) expressions (#26373)
• snmpreceiver: SNMP values of type Counter64 were seen as unsupported, because the returned data type unint64 was unhandeled. (#23897, #26119)
• pkg/stanza: Fix issue unsupported type 'syslog_parser' (#26452)
