🛑 Breaking changes 🛑

• confighttp: Make the client config options max_idle_conns, max_idle_conns_per_host, max_conns_per_host, and idle_conn_timeout integers (#9478)
  All four options can be set to 0 where they were previously set to null

🚩 Deprecations 🚩

• exporterhelper: Deprecate min_size_items and max_size_items in favor of min_size and max_size. (#12486)

💡 Enhancements 💡

• mdatagen: Add converter and provider module classes (#12467)

• pipeline: output pipeline name with signal as signal[/name] format in logs. (#12410)

• memorylimiter: Add support to configure min GC intervals for soft and hard limits. (#12450)

• otlpexporter: Update the stability level for logs, it has been as stable as traces and metrics for some time. (#12423)

• service: Create a new subcommand to dump the initial configuration after resolving/merging. (#11479)
  To use the print-initial-config subcommand, invoke the Collector with the subcommand and corresponding feature gate: otelcol print-initial-config --feature-gates=otelcol.printInitialConfig --config=config.yaml.
  Note that the feature gate enabling this flag is currently in alpha stability, and the subcommand may
  be changed in the future.

• memorylimiterprocessor: Add support for profiles. (#12453)

• otelcol: Converters are now available in the components command. (#11900, #12385)

• component: Mark module as stable (#9376)

• confmap: Surface YAML parsing errors when they happen at the top-level. (#12180)
  This adds context to some instances of the error "retrieved value (type=string) cannot be used as a Conf", which typically happens because of invalid YAML documents

• pprofile: Add LinkIndex attribute to the generated Sample type (#12485)

• exporterhelper: Stabilize exporter.UsePullingBasedExporterQueueBatcher and remove old batch sender (#12425)

• mdatagen: Update metadata schema with new fields without enforcing them (#12359)

🧰 Bug fixes 🧰

• service: Fix crash at startup when converting from v0.2.0 to v0.3.0 (#12438)
• service: fix bug in parsing service::telemetry configuration (#12437)
• exporterhelper: Fix bug where the error logged when conversion of data fails is always nil (#12510)
• mdatagen: Adds back missing import for filter when emitting resource attributes (#12455)

API Changelog

🛑 Breaking changes 🛑

  As a side effect of this change, no alternative implementation of the queue are supported and the Queue interface will be hidden.

• exporterhelper: Update MergeSplit function signature to use the new SizeConfig (#12486)

• extension, connector, processor, receiver, exporter, scraper: Remove deprecated Create* methods from Create*Func types. (#12305)
  The xconnector.CreateMetricsToProfilesFunc.CreateMetricsToProfiles method has been removed without a deprecation.

• component: Remove deprecated function and interface ConfigValidator and ValidateConfig. (#11524)

  • Use xconfmap.Validator and xconfmap.Validate instead.

• receiver, scraper, processor, exporter, extension: Remove deprecated MakeFactoryMap functions in favor of generic implementation (#12222)

• exporterhelper: Change the signature of the exporterhelper.WithQueueRequest to accept Encoding instead of the Factory. (#12509)

• component/componenttest: Removing the deprecated CheckReceiverMetrics and CheckReceiverTraces functions. (#12185)

🚩 Deprecations 🚩

• componenttest: Deprecated componenttest.TestTelemetry in favor of componenttest.Telemetry (#12419)
• connector, exporter, extension, processor, receiver, scraper: Add type parameter to NewNopSettings and deprecate NewNopSettingsWithType (#12305)
• exporterhelper: Deprecate MinSizeConfig and MaxSizeItems. (#12486)
• extension/extensionauth: Deprecate methods on *Func types. (#12480)
• extension/auth, extension/auth/authtest: Deprecate extension/auth and the related test module in favor of extension/extensionauth (#12478)

  Creates interface ExposeExporters in service/hostcapabilities to expose GetExporters function.
  Creates interface ModuleInfo in service/hostcapabilities to expose GetModuleInfos function.

💡 Enhancements 💡

• exporterhelper: Adds the config API to support serialized bytes based batching (#3262)
• configauth: Add the omitempty mapstructure tag to struct fields (#12191)
  This results in unset fields not being rendered when marshaling.
• confighttp: Add the omitempty mapstructure tag to struct fields (#12191)
  This results in unset fields not being rendered when marshaling.
• otelcol: Converters are now available in the components command. (#11900, #12385)
