  • NewMetricsRequestExporter: a new exporter helper for metrics.
  • NewTracesRequestExporter: a new exporter helper for traces.
  • Request: an interface for client-defined requests.
  • RequestItemsCounter: an optional interface for counting the number of items in a Request.

💡 Enhancements 💡

• extension: Add optional ConfigWatcher interface (#6596)
  Extensions implementing this interface will be notified of the Collector's effective config.

  This allows providing the Collector's configuration as a marshaled confmap.Conf object
  from a ConfigProvider

• service: Add CollectorConf field to service.Settings (#6596)
  This field is intended to be used by the Collector to pass its effective configuration to the service.

v0.82.0

Images and binaries here: https://github.com/open-telemetry/opentelemetry-collector-releases/releases/tag/v0.82.0

🛑 Breaking changes 🛑

• service: Enable configuration of collector telemetry through prometheus reader (#7641)
  These options are still experimental. To enable them, users must enable both
  telemetry.useOtelForInternalMetrics and telemetry.useOtelWithSDKConfigurationForInternalTelemetry
  feature gates. This change updates metric_readers to readers to align with the configuration
  working group.

• service: Remove experimental metric_readers.args and metric_reader.type config options. (#7641)
  These options were experimental and did not have any effect on the configuration of
  the collector's telemetry. The change aligns the configuration with the latest iteration
  of the configuration json schema, which may still change in the future.

💡 Enhancements 💡

• service: Add support for exporting internal metrics to the console (#7641)
  Internal collector metrics can now be exported to the console
  using the otel-go stdout exporter.

• service: Add support for interval and timeout configuration in periodic reader (#7641)

• service: Add support for span processor configuration for internal traces (#8106)
  These options are still experimental. To enable them, users must enable both
  telemetry.useOtelForInternalMetrics and telemetry.useOtelWithSDKConfigurationForInternalTelemetry
  feature gates.

• service: Add support for OTLP export for internal metrics (#7641)
  Internal collector metrics can now be exported via OTLP
  using the otel-go otlpgrpc and otlphttp exporters.

• scraperhelper: Adding optional timeout field to scrapers (#7951)

• otlpreceiver: Add http url paths per signal config options to otlpreceiver (#7511)

• otlphttpexporter: Add support for trailing slash in endpoint URL (#8084)
  URLs like http://localhost:4318/ will now be treated as if they were http://localhost:4318

🧰 Bug fixes 🧰

• connector: Fix connector validation (#7892)
  Validation of connectors was too aggressive such that a connector that was used in any combination of unsupported roles would fail.
  Instead, validation should pass as long as each use of the connector has a supported corresponding use.
