🛑 Breaking changes 🛑

• service/telemetry: Mark telemetry.disableAddressFieldForInternalTelemetry as beta, usage of deprecated service::telemetry::address are ignored (#12756)
  To restore the previous behavior disable telemetry.disableAddressFieldForInternalTelemetry feature gate.
• exporterbatch: Remove deprecated fields min_size_items and max_size_items from batch config. (#12684)

🚩 Deprecations 🚩

• otlpexporter: Mark BatcherConfig as deprecated, use sending_queue::batch instead (#12726)
• exporterhelper: Deprecate blocking in favor of block_on_overflow. (#12710)
• exporterhelper: Deprecate configuring exporter batching separately. Use sending_queue::batch instead. (#12772)
  Moving the batching configuration to sending_queue::batch requires setting sending_queue::sizer to items
  which means that sending_queue::queue_size needs to be also increased by the average batch size number (roughly
  x5000 for the default batching configuration).
  See https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/exporterhelper#configuration

💡 Enhancements 💡

• exporterhelper: Add support to configure batching in the sending queue. (#12746)

• exporterhelper: Add support for wait_for_result, remove disabled_queue (#12742)
  This has a side effect for users of the experimental BatchConfig with the queue disabled, since not this is | uses only NumCPU() consumers.

• exporterhelper: Allow exporter memory queue to use different type of sizers. (#12708)

• service: Add "telemetry.newPipelineTelemetry" feature gate to inject component-identifying attributes in internal telemetry (#12217)
  With the feature gate enabled, all internal telemetry (metrics/traces/logs) will include some of
  the following instrumentation scope attributes:

  • otelcol.component.kind
  • otelcol.component.id
  • otelcol.pipeline.id
  • otelcol.signal
  • otelcol.signal.output

  These attributes are defined in the Pipeline Component Telemetry RFC,
  and identify the component instance from which the telemetry originates.
  They are added automatically without changes to component code.

  These attributes were already included in internal logs as regular log attributes, starting from
  v0.120.0. For consistency with other signals, they have been switched to scope attributes (with
  the exception of logs emitted to standard output), and are now enabled by the feature gate.

  Please make sure that the exporter / backend endpoint you use has support for instrumentation
  scope attributes before using this feature. If the internal telemetry is exported to another
  Collector, a transform processor could be used to turn them into other kinds of attributes if
  necessary.

• exporterhelper: Enable support to do batching using bytes sizer (#12751)

• service: Add config key to set metric views used for internal telemetry (#10769)
  The service::telemetry::metrics::views config key can now be used to explicitly set the list of
  metric views used for internal telemetry, mirroring meter_provider::views in the SDK config.
  This can be used to disable specific internal metrics, among other uses.

  This key will cause an error if used alongside other features which would normally implicitly create views, such as:

  • not setting service::telemetry::metrics::level to detailed;
  • enabling the telemetry.disableHighCardinalityMetrics feature flag.

🧰 Bug fixes 🧰

• exporterhelper: Fix order of starting between queue and batch. (#12705)
