Release notes

Sourced from go.opentelemetry.io/otel's releases.

Release v1.45.0/v0.67.0/v0.21.0/v0.0.18

Overview

Added

• Add experimental observability metrics to BatchProcessor in go.opentelemetry.io/otel/sdk/log. (#7124)
• Add the experimental WithUnsafeAttributes no-copy attribute option to go.opentelemetry.io/otel/metric/x for future performance improvements. This API is a work in progress. (#8251)
• Add Map and MapValue functions for the new MAP attribute type in go.opentelemetry.io/otel/attribute. (#8445)
• Support MAP attributes in go.opentelemetry.io/otel/exporters/otlp/otlptrace. (#8453)
• Support MAP attributes in go.opentelemetry.io/otel/exporters/otlp/otlplog. (#8453)
• Support MAP attributes in go.opentelemetry.io/otel/exporters/otlp/otlpmetric. (#8453)
• Support MAP attributes in go.opentelemetry.io/otel/exporters/zipkin. (#8453)
• Apply AttributeValueLengthLimit recursively to values contained in attribute.MAP attributes in go.opentelemetry.io/otel/sdk/trace. (#8454)
• Remove duplicate keys from attribute.MAP values in go.opentelemetry.io/otel/sdk/resource using last-value-wins semantics. (#8471)
• Remove duplicate keys by default from attribute.MAP values in instrumentation scope attributes in go.opentelemetry.io/otel/sdk/log using last-value-wins semantics. (#8471)
• Remove duplicate keys by default from attribute.MAP values in span, event, link, and instrumentation scope attributes in go.opentelemetry.io/otel/sdk/trace using last-value-wins semantics. (#8471)
• Remove duplicate keys by default from attribute.MAP values in measurement and instrumentation scope attributes in go.opentelemetry.io/otel/sdk/metric using last-value-wins semantics. (#8471)
• Extend WithAllowKeyDuplication in go.opentelemetry.io/otel/sdk/log to disable duplicate-key removal in attribute.MAP values for instrumentation scope attributes. (#8471)
• 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.

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.
