🐛 Known bugs 🐛

• The ocb binary has an identified bug caused by the fact that some of the providers have been marked stable and the default providers in the ocb binary still use the unstable version. In order to fix this explicitly add the default providers in your otel builder config, if not already configured:

providers:
  - gomod: go.opentelemetry.io/collector/confmap/provider/envprovider v1.15.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/fileprovider v1.15.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/httpprovider v0.109.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/httpsprovider v0.109.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/yamlprovider v0.109.0

Alternatively you can pass the --skip-strict-version-check flag.

🛑 Breaking changes 🛑

• scraperhelper: Remove deprecated ObsReport, ObsReportSettings, NewObsReport types/funcs (#11086)
• confmap: Remove stable confmap.strictlyTypedInput gate (#11008)
• confmap: Removes stable confmap.unifyEnvVarExpansion feature gate. (#11007)
• ballastextension: Removes the deprecated ballastextension (#10671)
• service: Removes stable service.disableOpenCensusBridge feature gate (#11009)

🚩 Deprecations 🚩

• processorhelper: These funcs are not used anywhere, marking them deprecated. (#11083)

🚀 New components 🚀

• extension/experimental/storage: Move extension/experimental/storage into a separate module (#11022)

💡 Enhancements 💡

• configtelemetry: Add guidelines for each level of component telemetry (#10286)

• service: move useOtelWithSDKConfigurationForInternalTelemetry gate to beta (#11091)

• service: implement a no-op tracer provider that doesn't propagate the context (#11026) The no-op tracer provider supported by the SDK incurs a memory cost of propagating the context no matter what. This is not needed if tracing is not enabled in the Collector. This implementation of the no-op tracer provider removes the need to allocate memory when tracing is disabled.

• envprovider: Mark module as stable (#10982)

• fileprovider: Mark module as stable (#10983)

• processor: Add incoming and outgoing counts for processors using processorhelper. (#10910) Any processor using the processorhelper package (this is most processors) will automatically report incoming and outgoing item counts. The new metrics are:

  • otelcol_processor_incoming_spans
  • otelcol_processor_outgoing_spans
  • otelcol_processor_incoming_metric_points
  • otelcol_processor_outgoing_metric_points
  • otelcol_processor_incoming_log_records
  • otelcol_processor_outgoing_log_records

🧰 Bug fixes 🧰

• configgrpc: Change the value of max_recv_msg_size_mib from uint64 to int to avoid a case where misconfiguration caused an integer overflow. (#10948)
• exporterqueue: Fix a bug in persistent queue that Offer can becomes deadlocked when queue is almost full (#11015)

• connector: Remove deprecated connector builder (#11019)
