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. (#8383)

Pull Request Overview

No merge-blocking code or security findings remain after synthesis. The required build and test validation scenarios are missing, so compatibility with the updated dependency graph should be verified before merging.

About this PR

• Run the build and existing test suite, and verify the regenerated dependency checksums before merging.

Test suggestions

• Verify the project resolves the updated OTLP trace exporter and builds successfully.
• Run the existing test suite to verify compatibility with the updated dependency graph.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify the project resolves the updated OTLP trace exporter and builds successfully.
2. Run the existing test suite to verify compatibility with the updated dependency graph.
