v1.56.0/v0.150.0

💡 Enhancements 💡

• cmd/mdatagen: Add custom validation support for Go config structs (#14563)

v1.55.0/v0.149.0

💡 Enhancements 💡

• cmd/mdatagen: Added ability to generate required fields validation to config go structs generated by mdatagen (#14563)

🧰 Bug fixes 🧰

• cmd/mdatagen: Fix RootPackage to use go module root instead of git repo root (#14801) Fixes issue with running mdatagen when the git repository root is different from the go module root.

v1.54.0/v0.148.0

🛑 Breaking changes 🛑

• cmd/mdatagen: Generate a per-metric config type <MetricName>Config for each metric when reaggregation_enabled: true (#14689) Metrics with aggregatable attributes get AggregationStrategy and EnabledAttributes []<MetricName>AttributeKey fields; others get Enabled only. Typed attribute key constants (e.g. DefaultMetricAttributeKeyStringAttr) replace []string, eliminating runtime attribute slice allocations. Validation errors now list valid attributes and strategies by name. Components using reaggregation_enabled: true will need to update references to MetricConfig.

• pdata/pprofile: Update protoID for message Sample fields (#14652)

💡 Enhancements 💡

• cmd/mdatagen: Extend mdatagen tool to generate go config structs for OpenTelemetry collector components. (#14561) The component config go code is generated from config section of the metadata.yaml file.

• cmd/mdatagen: Extend mdatagen tool to generate config JSON schema for OpenTelemetry components. (#14543) The component config JSON schema is generated from config section of the metadata.yaml file.

• cmd/mdatagen: Schema generation for mdatagen-controlled config parts (#14562) The schema is generated in separate yaml file and used to create full component schema.

• pdata/pprofile: Implement reference based attributes in Profiles (#14546)

• pkg/pdata: Upgrade the OTLP protobuf definitions to version 1.10.0 (#14766)

• pkg/service: The internal status reporter no longer drops repeated Ok and RecoverableError statuses (#14282) Status events can now carry metadata and there's value in allowing them to be emitted despite the status value itself not changing.

• pkg/xexporterhelper: Add logic to cleanup partitions from memory which are not being used for specific time period. (#14526)

• pkg/xpdata: Add NewEntity constructor, Entity.CopyToResource, and EntityAttributeMap.All to pdata/xpdata/entity (#14659)

🧰 Bug fixes 🧰

• cmd/mdatagen: Preserve custom extensions (e.g., x-customType, x-pointer) during schema reference resolution. (#14713, #14565) Fixes an issue where custom properties defined locally on a node were overwritten and lost when resolving a $ref to an external/internal schema.

• pkg/xexporterhelper: Fix race when partition is being removed from LRU and new items are being added at the same time. (#14526)

v1.53.0/v0.147.0

💡 Enhancements 💡

• pkg/exporterhelper: Add metadata_keys configuration to sending_queue.batch.partition to partition batches by client metadata (#14139) The metadata_keys configuration option is now available in the sending_queue.batch.partition section for all exporters. When specified, batches are partitioned based on the values of the listed metadata keys, allowing separate batching per metadata partition. This feature is automatically configured when using exporterhelper.WithQueue().

• pkg/xexporterhelper: Add code structure to handle unbounded partitions in sending queue. (#14526)

🧰 Bug fixes 🧰

• pkg/config/configmiddleware: Add context.Context to gRPC middleware interface constructors. (#14523)
• pkg/extensionmiddleware: Add context.Context to gRPC middleware interface constructors. (#14523) This is a breaking API change for components that implement or use extensionmiddleware.

v1.52.0/v0.146.1

v0.146.0

🛑 Breaking changes 🛑

• cmd/mdatagen: Flatten the metric stability field (#14113) So we better match the weaver schema. Additional deprecation data can be set within the deprecated field.

🚩 Deprecations 🚩

• pdata/pprofile: Declare removed aggregation elements as deprecated. (#14528)

💡 Enhancements 💡

• cmd/mdatagen: Add entity association requirement for metrics and events when entities are defined (#14284)
• pkg/otelcol: Gate process signals behind build tags (#14542) Particularly for Wasm on JS, there are no invalid process signal references, which would cause build failures.

v1.51.0/v0.145.0

💡 Enhancements 💡

• pkg/config/configgrpc: add client info to context before server authentication (#12836)
• pkg/xscraperhelper: Add AddProfilesScraper similar to scraperhelper.AddMetricsScraper (#14427)

🧰 Bug fixes 🧰

• pkg/config/configoptional: Fix Unmarshal methods not being called when config is wrapped inside Optional (#14500) This bug notably manifested in the fact that the sending_queue::batch::sizer config for exporters stopped defaulting to sending_queue::sizer, which sometimes caused the wrong units to be used when configuring sending_queue::batch::min_size and max_size.

  As part of the fix, xconfmap exposes a new xconfmap.WithForceUnmarshaler option, to be used in the Unmarshal methods of wrapper types like configoptional.Optional to make sure the Unmarshal method of the inner type is called.

  The default behavior remains that calling conf.Unmarshal on the confmap.Conf passed as argument to an Unmarshal method will skip any top-level Unmarshal methods to avoid infinite recursion in standard use cases.

v1.50.0/v0.144.0

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

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

v1.49.0/v0.143.0

🛑 Breaking changes 🛑

• pkg/xprocessor: Use pointer receivers in xprocessor factory methods for consistency with other factories. (#14348)

v1.48.0/v0.142.0

🛑 Breaking changes 🛑

• pdata/xpdata: Rename Entity.IDAttributes() to Entity.IdentifyingAttributes() and Entity.DescriptionAttributes() to Entity.DescriptiveAttributes() to align with OpenTelemetry specification terminology for attributes. (#14275)
• pkg/exporterhelper: Use configoptional.Optional for the exporterhelper.QueueBatchConfig (#14155) It's recommended to change the field type in your component configuration to be configoptional.Optional[exporterhelper.QueueBatchConfig] to keep the enabled subfield. Use configoptional.Some(exporterhelper.NewDefaultQueueConfig()) to enable by default. Use configoptional.Default(exporterhelper.NewDefaultQueueConfig()) to disable by default.

🚩 Deprecations 🚩

• pkg/service: Deprecate Settings.LoggingOptions and telemetry.LoggerSettings.ZapOptions, add telemetry.LoggerSettings.BuildZapLogger (#14002) BuildZapLogger provides a more flexible way to build the Zap logger, since the function will have access to the zap.Config. This is used in otelcol to install a Windows Event Log output when the zap config does not specify any file output.

💡 Enhancements 💡

• pdata/pprofile: add ProfileCount() (#14239)

🧰 Bug fixes 🧰

• pkg/confmap: Ensure that embedded structs are not overwritten after Unmarshal is called (#14213) This allows embedding structs which implement Unmarshal and contain a configopaque.String.

v1.47.0/v0.141.0

🛑 Breaking changes 🛑

• pkg/config/configgrpc: Replace component.Host parameter of ToServer/ToClientConn by map of extensions (#13640) Components must now pass the map obtained from the host's GetExtensions method instead of the host itself.

  Nil may be used in tests where no middleware or authentication extensions are used.

• pkg/config/confighttp: Replace component.Host parameter of ToServer/ToClient by map of extensions (#13640) Components must now pass the map obtained from the host's GetExtensions method instead of the host itself.

💡 Enhancements 💡

• pkg/pdata: Upgrade the OTLP protobuf definitions to version 1.9.0 (#14128)

v1.45.0/v0.139.0

🛑 Breaking changes 🛑

• all: Change type of configgrpc.ClientConfig.Headers, confighttp.ClientConfig.Headers, and confighttp.ServerConfig.ResponseHeaders (#13930) configopaque.MapList is a new alternative to map[string]configopaque.String which can unmarshal both maps and lists of name/value pairs.

  For example, if headers is a field of type configopaque.MapList, then the following YAML configs will unmarshal to the same thing:

  headers:
    "foo": "bar"
  
  headers:
  - name: "foo"
    value: "bar"

• pdata/pprofile: Update SetFunction to return the function's ID rather than update the Line (#14016, #14032)

• pdata/pprofile: Update SetMapping to return the mapping's ID rather than update the Location (#14016, #14030)

• pkg/otelcol: Require a telemetry factory to be injected through otelcol.Factories (#4970) otelcol.Factories now has a required Telemetry field, which contains the telemetry factory to be used by the service. Set it to otelconftelemetry.NewFactory() for the existing behavior.

• pkg/pdata: Remove unused generated code from pprofile (#14073) Experimental package, ok to break since not used.

💡 Enhancements 💡

• pdata/pprofile: Introduce SetStack method (#14007)
• pdata/xpdata: Add high-level Entity API for managing entities attached to resources (#14042) Introduces Entity, EntitySlice, and EntityAttributeMap types that provide a user-friendly interface for working with resource entities. The new API ensures consistency between entity and resource attributes by sharing the underlying attribute map, and prevents attribute conflicts between entities. This API may eventually replace the generated protobuf-based API for better usability.

🛑 Breaking changes 🛑

• configauth: removing deprecated methods GetServerAuthenticatorContext and GetClientAuthenticatorContext (#9808)

• connector,exporter,receiver,extension,processor: Remove deprecated funcs/structs (#10423) Remove the following funcs & structs:

  • connector.CreateSettings -> connector.Settings

• component/componenttest: Add optional ...attribute.KeyValue argument to TestTelemetry.CheckExporterMetricGauge. (#10593)

• confighttp: Auth data type signature has changed (#4806) As part of the linked PR, the auth attribute was moved from configauth.Authentication to a new AuthConfig, which contains a configauth.Authentication. For end-users, this is a non-breaking change. For users of the API, create a new AuthConfig using the configauth.Authentication instance that was being used before.

• mdatagen: Remove WithAttributes option from the telemetry builder constructor. (#10608) Attribute sets for async instruments now can be set as options to callback setters and async instruments initializers. This allows each async instrument to have its own attribute set.

• service/extensions: Adds Options to extensions.New. (#10728) This is only a breaking change if you are depending on extensions.New's signature. Calls to extensions.New are not broken.
