🛑 Breaking changes 🛑

• processorhelper: Update incoming/outgoing metrics to a single metric with a otel.signal attributes. (#11144)
  The following metrics were added in the previous version

  • 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

  They are being replaced with the following to more closely align with OTEP 259:

  • otelcol_processor_incoming_items
  • otelcol_processor_outgoing_items

• processorhelper: Remove deprecated [Traces|Metrics|Logs]Inserted funcs (#11151)

• config: Mark UseLocalHostAsDefaultHostfeatureGate as stable (#11235)

🚩 Deprecations 🚩

• processorhelper: deprecate accepted/refused/dropped metrics (#11201)
  The following metrics are being deprecated as they were only used in a single
  processor:
  • otelcol_processor_accepted_log_records
  • otelcol_processor_accepted_metric_points
  • otelcol_processor_accepted_spans
  • otelcol_processor_dropped_log_records
  • otelcol_processor_dropped_metric_points
  • otelcol_processor_dropped_spans
  • otelcol_processor_refused_log_records
  • otelcol_processor_refused_metric_points
  • otelcol_processor_refused_spans

💡 Enhancements 💡

• pdata: Add support to MoveTo for Map, allow avoiding copies (#11175)
• mdatagen: Add stability field to telemetry metrics, allowing the generated description to include a stability string. (#11160)
• confignet: Mark module as Stable. (#9801)
• confmap/provider/envprovider: Support default values when env var is empty (#5228)
• mdatagen: mdatagen validateMetrics() support validate metrics in telemetry.metric (#10925)
• service/telemetry: Mark useOtelWithSDKConfigurationForInternalTelemetry as stable (#7532)
• mdatagen: Use cobra for the command, add version flag (#11196)

🧰 Bug fixes 🧰

• service: Ensure process telemetry is registered when internal telemetry is configured with readers instead of an address. (#11093)

• mdatagen: Fix incorrect generation of metric tests with boolean attributes. (#11169)

• otelcol: Fix the Windows Event Log configuration when running the Collector as a Windows service. (#5297, #11051)

• builder: Honor build_tags in config (#11156)

• builder: Fix version for providers in the default config (#11123)

• cmd/builder: Temporarily disable strict versioning checks (#11129, #11152)
  The strict versioning check may be enabled by default in a future version once all configuration providers are stabilized.

• confmap: Fix loading config of a component from a different source. (#11154)
  This issue only affected loading the whole component config, loading parts of a component config from a different source was working correctly.
