[1.46.0/0.68.0/0.22.0/0.0.19] - 2026-08-25

This release is the last to support [Go 1.25]. The next release will require at least [Go 1.26].

Added

• Support testing of [Go 1.27]. (#8811)
• Support http/json protocol in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#8273, #8775, #8831)
• Add Hasher struct and methods in go.opentelemetry.io/otel/attribute to compute authoritative Distinct hashes incrementally for attribute filtering and deduplication. (#8598)

Changed

• Lazily evaluate filtered and dropped attributes on measurement hot paths in go.opentelemetry.io/otel/sdk/metric to avoid unnecessary attribute set allocations. (#8598)
• Add ErrExporterShutdown to go.opentelemetry.io/otel/sdk/log and return it from the go.opentelemetry.io/otel/exporters/stdout/stdoutlog, go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp exporters when Export is called after Shutdown. (#8773)
• Clarify in go.opentelemetry.io/otel/log that calling Logger.Enabled is optional and that cached results can become stale. (#8764)

Fixed

• Export dropped attribute counts in OTLP log records from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8829)
• Name span events created from OpenTracing logs after the event log field, falling back to log, instead of always using an empty name in go.opentelemetry.io/otel/bridge/opentracing. (#8648)
• Count exception attributes omitted due to the attribute count limit as dropped in go.opentelemetry.io/otel/sdk/log. (#8796)
• Prevent log record and instrumentation scope attributes with empty keys from reaching processors and exporters in go.opentelemetry.io/otel/sdk/log. (#8797)
• Fix a data race when span attributes are read concurrently in go.opentelemetry.io/otel/sdk/trace. (#8706)
• Prevent a panic in (*Set).Filter when called on a nil receiver in go.opentelemetry.io/otel/attribute. (#8792)
• The simple span and log processors record otel.sdk.processor.{span,log}.processed when the record is submitted to the exporter instead of after the export completes, and no longer set error.type from the export outcome, in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log. (#8705)
• Prevent Resource.MarshalLog from panicking on nil resources in go.opentelemetry.io/otel/sdk/resource. (#8758)

[1.45.0/0.67.0/0.21.0/0.0.18] - 2026-08-03

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.
