  • all: Added support for go1.24, bumped minimum version to 1.23 (#12370)
  • mdatagen: Removing deprecated generated funcs and a few test funcs as well. (#12304)
  • service: Align component logger attributes with those defined in RFC (#12217) See Pipeline Component Telemetry RFC

💡 Enhancements 💡

  • otlpreceiver: Update stability for logs (#12335)
  • exporterhelper: Implement sync disabled queue used when batching is enabled. (#12245)
  • exporterhelper: Enable the new pull-based batcher in exporterhelper (#12291)
  • exporterhelper: Update queue size after the element is done exported (#12399) After this change the active queue size will include elements in the process of being exported.
  • otelcol: Add featuregate command to display information about available features (#11998) The featuregate command allows users to view detailed information about feature gates including their status, stage, and description.

🧰 Bug fixes 🧰

  • memorylimiter: Logger no longer attributes to single signal, pipeline, or component. (#12217)
  • otlpreceiver: Logger no longer attributes to random signal when receiving multiple signals. (#12217)
  • exporterhelper: Fix undefined behavior access to request after send to next component. This causes random memory access. (#12281)
  • exporterhelper: Fix default batcher to correctly call all done callbacks exactly once (#12247)
  • otlpreceiver: Fix OTLP http receiver to correctly set Retry-After (#12367)
  • otlphttpexporter: Fix parsing logic for Retry-After in OTLP http protocol. (#12366) The value of Retry-After field can be either an HTTP-date or delay-seconds and the current logic only parsed delay-seconds.
  • cmd/builder: Ensure unique aliases for modules with same suffix (#12201)

API Changelog

🛑 Breaking changes 🛑

  • configauth: Remove NewDefaultAuthentication (#12223) The value returned by this function will always cause an error on startup. In configgrpc.Client/ServerConfig.Auth, nil should be used instead to disable authentication.

  • otelcol: Make the ConfigProvider interface a struct (#12297) Calls to NewConfigProvider will now return *ConfigProvider, but will otherwise work the same as before.

  • extension: Remove extension.Settings.ModuleInfo (#12296)

    • The functionality is now available as an optional, hidden interface on service's implementation of the Host

  • component: Remove deprecated field component.TelemetrySettings.MetricsLevel. (#11061)

  • confighttp: Add ToClientOption type and add it to signature of ToClient method. (#12353)

    • This has no use for now, it may be used in the future.

  • mdatagen: Remove unused not_component config for mdatagen (#12237)

🚩 Deprecations 🚩

  • component/componenttest: Deprecate CheckReceiverMetrics in componenenttest (#12185) Use the metadatatest.AssertEqualMetric series of functions instead of obsreporttest.CheckReceiverMetrics
  • component/componenttest: Deprecate CheckReceiverTraces in componenenttest (#12185) Use the metadatatest.AssertEqualMetric series of functions instead of obsreporttest.CheckReceiverTraces
  • component: Deprecate ConfigValidator and ValidateConfig (#11524) Please use Validator and Validate respectively from xconfmap.
  • receiver, scraper, processor, exporter, extension: Deprecate existing MakeFactoryMap functions in favor of generic implementation (#12222)
  • extension, connector, processor, receiver, exporter, scraper: Deprecate Create* methods from Create*Func types. (#12305)
  • extensiontest, connectortest, processortest, receivertest, exportertest, scrapertest: Deprecate *test.NewNopSettings in favor of *test.NewNopSettingsWithType (#12305)

🚀 New components 🚀

  • xconfmap: Create the xconfmap module and add the Validator interface and Validate function to facilitate config validation (#11524)

💡 Enhancements 💡

  • configgrpc: Add the omitempty mapstructure tag to struct fields (#12191) This results in unset fields not being rendered when marshaling.
  • confignet: Add the omitempty mapstructure tag to struct fields (#12191) This results in unset fields not being rendered when marshaling.
  • configtls: Add the omitempty mapstructure tag to struct fields (#12191) This results in unset fields not being rendered when marshaling.
  • consumer: Clarify that data cannot be accessed after Consume* func is called. (#12284)
  • pdata/pprofile: Introduce aggregation temporality constants (#12253)

🧰 Bug fixes 🧰

  • configgrpc: Apply configured Headers automatically (#12307) configgrpc now calls metadata.AppendToOutgoingContext automatically in an interceptor. Components that were manually using metadata.NewOutgoingContext as a workaround no longer need to do so, unless they are overwriting or adding header keys.

  • configgrpc: Set Auth to nil in NewDefaultClientConfig/NewDefaultServerConfig (#12223) The value that was used previously would always cause an error on startup.

  • exporterqueue: Fix async queue to propagate cancellation all they way to the queue (#12282)

  • otlpreceiver: Fix OTLP http receiver to correctly set Retry-After (#12367)

  • extension: Explicitly error out at extension creation time if there is a type mismatch. (#12305)
