🛑 Breaking changes 🛑

• pkg/exporterhelper: Change verbosity level for otelcol_exporter_queue_batch_send_size metric to detailed. (#14278)
• pkg/service: Remove deprecated telemetry.disableHighCardinalityMetrics feature gate. (#14373)
• pkg/service: Remove deprecated service.noopTracerProvider feature gate. (#14374)

🚩 Deprecations 🚩

• exporter/otlp_grpc: Rename otlp exporter to otlp_grpc exporter and add deprecated alias otlp. (#14403)
• exporter/otlp_http: Rename otlphttp exporter to otlp_http exporter and add deprecated alias otlphttp. (#14396)

💡 Enhancements 💡

• cmd/builder: Avoid duplicate CLI error logging in generated collector binaries by relying on cobra's error handling. (#14317)

• cmd/mdatagen: Add the ability to disable attributes at the metric level and re-aggregate data points based off of these new dimensions (#10726)

• cmd/mdatagen: Add optional display_name and description fields to metadata.yaml for human-readable component names (#14114)
  The display_name field allows components to specify a human-readable name in metadata.yaml.
  When provided, this name is used as the title in generated README files.
  The description field allows components to include a brief description in generated README files.

• cmd/mdatagen: Validate stability level for entities (#14425)

• pkg/xexporterhelper: Reenable batching for profiles (#14313)

• receiver/nop: add profiles signal support (#14253)

🧰 Bug fixes 🧰

• pkg/exporterhelper: Fix reference count bug in partition batcher (#14444)

API Changelog

🛑 Breaking changes 🛑

• pkg/config/confighttp: Replace ServerConfig.Endpoint with NetAddr confignet.AddrConfig, enabling more flexible transport configuration. (#14187, #8752)
  This change adds "transport" as a configuration option, allowing users to specify
  different transport protocols (e.g., "tcp", "unix").

🚩 Deprecations 🚩

• pkg/scraperhelper: Deprecate the AddScraper method. (#14428)

🚀 New components 🚀

• pkg/xscraperhelper: Add xscraperhelper for the experimental OTel profiling signal. (#14235)

💡 Enhancements 💡

• all: Add support for deprecated component type aliases (#14208)
  To add a deprecated type alias to a component factory, use the WithDeprecatedTypeAlias option.

  return xexporter.NewFactory(
      metadata.Type,
      createDefaultConfig,
      xexporter.WithTraces(createTracesExporter, metadata.TracesStability),
      xexporter.WithDeprecatedTypeAlias("old_component_name"),
  )

  When the alias is used in configuration, a deprecation warning will be automatically logged, and the component will function normally using the original implementation.

• cmd/mdatagen: Add the ability to disable attributes at the metric level and re-aggregate data points based off of these new dimensions (#10726)

• extension/xextension: Add deprecated type alias support for extensions via xextension module (#14208)
  Extensions can now register deprecated type aliases using the experimental xextension.WithDeprecatedTypeAlias option.

  return xextension.NewFactory(
      metadata.Type,
      createDefaultConfig,
      createExtension,
      metadata.Stability,
      xextension.WithDeprecatedTypeAlias("old_extension_name"),
  )

  When the alias is used in configuration, a deprecation warning will be automatically logged, and the extension will function normally using the original implementation.

• pkg/consumer/consumertest: Add ProfileCount() (#14251)

• pkg/exporterhelper: Add support for profile samples metrics (#14423)

• pkg/receiverhelper: Add support for profile samples metrics (#14226)
