🛑 Breaking changes 🛑

• connector/failover: Remove deprecated field retry_gap and max_retries (#49583)

• connector/routing: Promote the connector.routing.defaultErrorModeIgnore feature gate to beta. The default error_mode is now ignore instead of propagate. (#48418) To restore the previous default of propagate, run the collector with the feature gate disabled by passing --feature-gates=-connector.routing.defaultErrorModeIgnore.

• processor/aws_ecs_attributes: Rename the component identifier from awsecsattributes to aws_ecs_attributes to follow the component naming guidelines. (#44476) The processor is still in development, so the old identifier is removed rather than kept as a deprecated alias.

• processor/filter: Promote the processor.filter.defaultErrorModeIgnore feature gate to stable. The default top-level error_mode is now permanently ignore instead of propagate. (#47232) The gate will be removed in v0.159.0.

• processor/tail_sampling: Fix metric units to comply with the UCUM specification (#49453)

• processor/transform: Promote the processor.transform.defaultErrorModeIgnore feature gate to stable. The default top-level error_mode is now permanently ignore instead of propagate. (#47231) The gate will be removed in v0.159.0.

• receiver/apache_spark: Fix metric units to comply with the UCUM specification (#49453)

• receiver/chrony: Fix metric units to comply with the UCUM specification (#49453)

• receiver/haproxy: Fix metric units to comply with the UCUM specification (#49453)

• receiver/host_metrics: Make the cpu attribute opt-in for hostmetrics CPU time and utilization metrics. (#49161) By default, system.cpu.time and system.cpu.utilization are now aggregated across logical CPUs and no longer include the cpu attribute. To restore the previous per-logical-CPU output, configure:

  receivers:
    hostmetrics:
      scrapers:
        cpu:
          metrics:
            system.cpu.time:
              attributes: [cpu, state]
            system.cpu.utilization:
              attributes: [cpu, state]

• receiver/host_metrics: Enable the system.cpu.logical.count metric by default in the CPU scraper. (#49325) To restore the previous behavior, disable the new metric by applying the following config:

  receivers:
    host_metrics:
      scrapers:
        cpu:
          metrics:
            system.cpu.logical.count:
              enabled: false

• receiver/memcached: Fix metric units to comply with the UCUM specification (#49453)

• receiver/mongodb: Fix metric units to comply with the UCUM specification (#49453)

• receiver/nginx: Fix metric units to comply with the UCUM specification (#49453)

v0.157.0

🛑 Breaking changes 🛑

• pkg/ottl: Break lambda arity validation into a separate function. (#49421) This allows statically verifying arity.

💡 Enhancements 💡

• internal/k8sinventory: Extract checkpoint package and update Observer interface to return startup errors. (#43602)

  • Extracted internal/k8sinventory/checkpoint as a shared package so checkpoint logic can be reused across observer implementations.
  • The Observer interface's Start method now returns an error, allowing callers to detect and propagate startup failures.

• pkg/ottl: Add LambdaActivation.IsArgBound and variadic lambda argument evaluation helpers. (#49191)

  • IsArgBound reports whether a positional argument maps to a named formal parameter or a blank ("_") placeholder.
  • Lambda evaluation helpers now normalize only bound arguments.

• pkg/pdatatest: Add IncludeHistogramExplicitBounds option to pmetricassert snapshot generation. (#49732) The option includes histogram explicit bounds without including other histogram datapoint values. Snapshot compaction preserves selected histogram datapoint assertion fields, including empty explicit bounds.

v0.156.0

🛑 Breaking changes 🛑

• all: handle breaking change in pdata/pprofile (#49373)
• pkg/ottl: Switch LambdaExpression arguments to be pointers. (#49420) These values are intended to be mutable and are passed by reference in normal use, so this keeps symmetry between the argument declaration and their use by the function.

💡 Enhancements 💡

• pkg/ottl: Add ottl.NewTestingLambdaExpression and internal helpers for implementing lambda-based OTTL functions. (#49180) Adds ottl.NewTestingLambdaExpression, a test helper that builds a LambdaExpression with a custom value body. The callback receives resolveBinding func(string) any to read formal parameters from the active local scope during evaluation.

  Also introduces internal helpers to support lambda-based OTTL functions:

  • funcutil.GetSliceOrMapValue coerces a getter result to pcommon.Slice or pcommon.Map.
  • funcutil.EvaluateBiFunction and funcutil.EvaluateBiPredicate bind two positional arguments, normalize them, and evaluate a LambdaActivation.
  • ottlcommon.NormalizeValue converts values, including pcommon.Value, into types used by OTTL comparisons.

• pkg/ottl: Add String() method to ottl.Statement, ottl.Condition, and ottl.ValueExpression that return the original OTTL text used during parsing. (#49415)

• processor/transform: Add exemplar context support to the transform processor, allowing metric_statements to read and modify exemplar fields on metric datapoints. (#49022)

🚀 New components 🚀

• processor/queuebatch: New queuebatchprocessor to replace the legacy batchprocessor. (#15047, #13582, #12022, #11308, #8272, #6046) New implementation is based exporterhelper, uses same configuration as sending_queue.

💡 Enhancements 💡

• cmd/mdatagen: Add first-class extended type aliases (int64, duration, opaque_string, id, opaque_map, etc.) to config schemas in metadata.yaml (#15513) Authors can now write type: int64, type: duration, type: opaque_string, type: id, or type: opaque_map directly as a property type in the config: section of metadata.yaml. Each alias expands to the correct JSON Schema representation and Go type automatically. Existing uses of standard JSON Schema types, format:, and x-customType: remain supported without migration.

• extension/memory_limiter: Promote the memory limiter extension to beta stability. (#14533)

🧰 Bug fixes 🧰

• cmd/mdatagen: Removes the extra line in the documentation.md around description (#15664)

• cmd/mdatagen: Auto-enable v1 metrics when legacy metric is enabled and v1 feature gate is on (#15650) When the v1 feature gate is enabled and a legacy metric is enabled, the corresponding v1 metric is now programmatically enabled so users don't need to add the v1 metric to their config.

• cmd/mdatagen: Fix incorrect collision warning for versioned metrics with different emitted names (#15648) Same name collision detection (type/attribute checks) was being used for versioned metrics with different names. This caused the legacy metric to be disabled which was incorrect and also a warning msg was being incorrectly logged that stated the metrics had the same name when in fact they had different names.

• cmd/mdatagen: Versioned metrics don't handle renamed attributes with same type (#15595) Versioned metrics need to support emitting legacy and latest attributes when the metric name is the same but the attributes names differ. This was not working when the attributes name changed but the type remained the same. Here we add support to versioned metrics with renamed attributes where those attributes have the same type.

• exporter/debug: Fix profile sample attribute formatting for non-string values (#15647) Previously, non-string values produced malformed output such as %!s(int64=42). Profile sample attributes now use the debug exporter's typed attribute format, such as Int(42). This will also change strings from hello-world to Str(hello-world).

• pkg/config/configtls: Fix goroutine and file descriptor leak when client_ca_file_reload is enabled (#9221) Every call to ServerConfig.LoadTLSConfig with client_ca_file_reload enabled started a file watcher goroutine that could never be stopped, since the reloader was not reachable from the returned *tls.Config. The client CA file is now checked for changes while TLS handshakes are served, at most once per second, matching how reload_interval already

Changed

• HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar now uses a time-unbiased sampling algorithm for exemplars. (#8306)
• ⚠️ Breaking Change: Use go.opentelemetry.io/otel/attribute.Value and go.opentelemetry.io/otel/attribute.KeyValue for log bodies and attributes in go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/log/logtest, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/sdk/log/logtest. (#8490)
• Encode log bodies and attributes as go.opentelemetry.io/otel/attribute.Value JSON in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#8490)
• Improve the performance of hashing BOOLSLICE, INT64SLICE, FLOAT64SLICE, and STRINGSLICE attribute values by avoiding reflection for short slices in go.opentelemetry.io/otel/attribute. (#8511)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_METRICS_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/metrics")) to preserve the previous behavior. (#8538)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_TRACES_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/traces")) to preserve the previous behavior. (#8538)

Deprecated

• Deprecate WithExportBufferSize in go.opentelemetry.io/otel/sdk/log. The option remains available for source compatibility but no longer affects behavior; BatchProcessor no longer maintains a separate export-request buffer. (#8620)

Removed

• ⚠️ Breaking Change: Remove Kind, Value, KeyValue, their constructors, and attribute conversion helpers from go.opentelemetry.io/otel/log. (#8490)
• ⚠️ Breaking Change: Remove the AttributeValueLengthLimit and AttributeCountLimit fields from RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest; records produced by the factory now keep attribute limits disabled so test code can append exact attributes. (#8556)

Fixed

• Apply TLS certificates configured through environment variables to gRPC connections in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc.
• Prevent panics in go.opentelemetry.io/otel/bridge/opentracing when OpenTracing baggage is propagated concurrently with Span.SetBaggageItem.
• Fix an off-by-one error in FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar that prevented the first exemplar from being sampled after the reservoir was filled. (#8309)
• Interpret HTTP Retry-After header values as seconds instead of nanoseconds when retrying OTLP HTTP exports in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8383)
• Fix a memory leak in the Reservoir implementation in go.opentelemetry.io/otel/sdk/metric/exemplar, where storing the full context.Context pinned large objects such as gRPC transport buffers. (#8389)

• Add the go.opentelemetry.io/otel/semconv/v1.42.0 package. The package contains semantic conventions from the v1.42.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.41.0. (#8484)
• Add WithoutPanicRecording as a TracerProviderOption in go.opentelemetry.io/otel/sdk/trace to disable exception event recording for panics. (#8532)
• Add the go.opentelemetry.io/otel/semconv/v1.43.0 package. The package contains semantic conventions from the v1.43.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.42.0. (#8628)

Changed

• HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar now uses a time-unbiased sampling algorithm for exemplars. (#8306)
• ⚠️ Breaking Change: Use go.opentelemetry.io/otel/attribute.Value and go.opentelemetry.io/otel/attribute.KeyValue for log bodies and attributes in go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/log/logtest, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/sdk/log/logtest. (#8490)
• Encode log bodies and attributes as go.opentelemetry.io/otel/attribute.Value JSON in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#8490)
• Improve the performance of hashing BOOLSLICE, INT64SLICE, FLOAT64SLICE, and STRINGSLICE attribute values by avoiding reflection for short slices in go.opentelemetry.io/otel/attribute. (#8511)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_METRICS_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/metrics")) to preserve the previous behavior. (#8538)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_TRACES_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/traces")) to preserve the previous behavior. (#8538)

Deprecated

• Deprecate WithExportBufferSize in go.opentelemetry.io/otel/sdk/log. The option remains available for source compatibility but no longer affects behavior; BatchProcessor no longer maintains a separate export-request buffer. (#8620)

Removed

• ⚠️ Breaking Change: Remove Kind, Value, KeyValue, their constructors, and attribute conversion helpers from go.opentelemetry.io/otel/log. (#8490)
• ⚠️ Breaking Change: Remove the AttributeValueLengthLimit and AttributeCountLimit fields from RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest; records produced by the factory now keep attribute limits disabled so test code can append exact attributes. (#8556)

Fixed

• Apply TLS certificates configured through environment variables to gRPC connections in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc.
• Prevent panics in go.opentelemetry.io/otel/bridge/opentracing when OpenTracing baggage is propagated concurrently with Span.SetBaggageItem.
• Fix an off-by-one error in FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar that prevented the first exemplar from being sampled after the reservoir was filled. (#8309)
• Interpret HTTP Retry-After header values as seconds instead of nanoseconds when retrying OTLP HTTP exports in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8383)
• Fix a memory leak in the Reservoir implementation in go.opentelemetry.io/otel/sdk/metric/exemplar, where storing the full context.Context pinned large objects such as gRPC transport buffers. (#8389)
