🐛 Known bugs 🐛

• The ocb binary has an identified bug caused by the fact that some of the providers have been marked stable and the default providers in the ocb binary still use the unstable version. In order to fix this explicitly add the default providers in your otel builder config, if not already configured:

providers:
  - gomod: go.opentelemetry.io/collector/confmap/provider/envprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/fileprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/httpprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/httpsprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/yamlprovider v1.17.0

This release removes the logging exporter. See #11337 to migrate to the debug exporter.

🛑 Breaking changes 🛑

• service/telemetry: Change default metrics address to "localhost:8888" instead of ":8888" (#11251) This behavior can be disabled by disabling the feature gate telemetry.UseLocalHostAsDefaultMetricsAddress.
• loggingexporter: Removed the deprecated logging exporter. Use the debug exporter instead. (#11037). You can read issue #11337 for migration instructions.

🚩 Deprecations 🚩

• service/telemetry: Deprecate service::telemetry::metrics::address in favor of service::telemetry::metrics::readers. (#11205)
• processorhelper: Deprecate BuildProcessorMetricName as it's no longer needed since introduction of mdatagen (#11302)

💡 Enhancements 💡

• ocb: create docker images for OCB, per https://github.com/open-telemetry/opentelemetry-collector-releases/pull/671 (#5712) Adds standard Docker images for OCB to Dockerhub and GitHub, see hub.docker.com/r/otel/opentelemetry-collector-builder
• confighttp: Snappy compression to lazy read for memory efficiency (#11177)
• httpsprovider: Mark the httpsprovider as stable. (#11191)
• httpprovider: Mark the httpprovider as stable. (#11191)
• yamlprovider: Mark the yamlprovider as stable. (#11192)
• confmap: Allow using any YAML structure as a string when loading configuration including time.Time formats (#10659) Previously, fields with time.Time formats could not be used as strings in configurations

🧰 Bug fixes 🧰

• processorhelper: Fix data race condition, concurrent writes to the err variable, causes UB (Undefined Behavior) (#11350)
• cmd/builder: re-adds function to properly set and view version number of OpenTelemetry Collector Builder (ocb) binaries (#11208)

API Changes

🛑 Breaking changes 🛑

• service/telemetry: Change default metrics address to "localhost:8888" instead of ":8888" (#11251) This behavior can be disabled by disabling the feature gate 'telemetry.UseLocalHostAsDefaultMetricsAddress'.

• componentprofiles: Removed deprecated DataTypeProfiles. Use SignalProfiles instead. (#11312)

• configgrpc: Replace ToClientConn and ToServer with ToClientConnWithOptions and ToServerWithOptions. (#11271, #9480) ClientConfig.ToClientConn and ServerConfig.ToServer were deprecated in v0.110.0 in favor of ClientConfig.ToClientConnWithOptions and ServerConfig.ToServerWithOptions which use a more flexible option type. The original functions are now removed, and the new ones are renamed to the old names. The WithOptions names are kept as deprecated aliases for now.

• exporterhelper: Removed deprecated QueueTimeout/TimeoutSettings aliases in favor of QueueConfig/TimeoutConfig. (#11264, #6767) NewDefaultQueueSettings and NewDefaultTimeoutSettings have been similarly renamed.

• exporterqueue: Remove deprecated Settings.DataType. Use Settings.Signal instead. (#11305)

• exportertest: Remove deprecated CheckConsumeContractParams.DataType. Use CheckConsumeContractParams.Signal instead. (#11305)

• component: Removed deprecated ErrDataTypeIsNotSupported, DataType, DataTypeTraces, DataTypeMetrics, and DataTypeLogs. Use pipeline.ErrSignalNotSupported, pipeline.Signal, pipeline.SignalTraces, pipeline.SignalMetrics, and pipeline.SignalLogs instead. (#11253)

• pdata/pprofile: Replace slices of values to slices of pointers for the Mapping, Location, Line, Function, AttributeUnit, Link, Value, Sample and Labels attributes. (#11339)

• receivertest: Remove deprecated CheckConsumeContractParams.DataType. Use CheckConsumeContractParams.Signal instead. (#11304)

• scraperhelper: Remove deprecated function NewScraperWithComponentType. (#11294)

• processorhelper: Remove deprecated funcs form processorhelper.ObsReport (#11289) The "otelcol_processor_dropped_log_records", "otelcol_processor_dropped_log_records" | and "otelcol_processor_dropped_spans" metrics are complete removed, before they were always record with 0 values.

🚩 Deprecations 🚩

• componentstatus: Deprecated NewInstanceIDWithPipelineIDs, AllPipelineIDsWithPipelineIDs, and WithPipelineIDs. Use NewInstanceID, AllPipelineIDs, and WithPipelines instead. (#11313)

• processorhelper: Deprecate unused and empty struct processorhelper.ObsReport (#11293)

• processor: Deprecate funcs that repeat "processor" in name (#11310) Factory.Create[Traces|Metrics|Logs|Profiles]Processor -> Factory.Create[Traces|Metrics|Logs|Profiles] Factory.[Traces|Metrics|Logs|Profiles]ProcessorStability -> Factory.[Traces|Metrics|Logs|Profiles]Stability

• receiver: Deprecate funcs that repeat "receiver" in name (#11287) Factory.Create[Traces|Metrics|Logs|Profiles]Receiver -> Factory.Create[Traces|Metrics|Logs|Profiles] Factory.[Traces|Metrics|Logs|Profiles]ReceiverStability -> Factory.[Traces|Metrics|Logs|Profiles]Stability

• receivertest: Deprecated NewNopFactoryForTypeWithSignal. Use NewNopFactoryForType instead. (#11304)

• service: Deprecates Config.PipelinesWithPipelineID, pipelines.ConfigWithPipelineID and GetExportersWithSignal interface implementation. Use Config.Pipelines, pipelines.Config, and GetExporters interface implementation instead. (#11303)
