Bumps go.opentelemetry.io/otel/log from 0.15.0 to 0.16.0.

Release notes

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

Release v0.16.0

Added

• Add the ReadOnlySpan and ReadWriteSpan interfaces to provide better control for accessing span data. (#1360)
• NewGRPCDriver function returns a ProtocolDriver that maintains a single gRPC connection to the collector. (#1369)
• Added documentation about the project's versioning policy. (#1388)
• Added NewSplitDriver for OTLP exporter that allows sending traces and metrics to different endpoints. (#1418)
• Added codeql worfklow to GitHub Actions (#1428)
• Added Gosec workflow to GitHub Actions (#1429)
• Add new HTTP driver for OTLP exporter in exporters/otlp/otlphttp. Currently it only supports the binary protobuf payloads. (#1420)

Changed

• Rename internal/testing to internal/internaltest. (#1449)
• Rename export.SpanData to export.SpanSnapshot and use it only for exporting spans. (#1360)
• Store the parent's full SpanContext rather than just its span ID in the span struct. (#1360)
• Improve span duration accuracy. (#1360)
• Migrated CI/CD from CircleCI to GitHub Actions (#1382)
• Remove duplicate checkout from GitHub Actions workflow (#1407)
• Metric array aggregator renamed exact to match its aggregation.Kind (#1412)
• Metric exact aggregator includes per-point timestamps (#1412)
• Metric stdout exporter uses MinMaxSumCount aggregator for ValueRecorder instruments (#1412)
• NewExporter from exporters/otlp now takes a ProtocolDriver as a parameter. (#1369)
• Many OTLP Exporter options became gRPC ProtocolDriver options. (#1369)
• Unify endpoint API that related to OTel exporter. (#1401)
• Optimize metric histogram aggregator to re-use its slice of buckets. (#1435)
• Metric aggregator Count() and histogram Bucket.Counts are consistently uint64. (1430)
• SamplingResult now passed a Tracestate from the parent SpanContext (#1432)
• Moved gRPC driver for OTLP exporter to exporters/otlp/otlpgrpc. (#1420)
• The TraceContext propagator now correctly propagates TraceState through the SpanContext. (#1447)
• Metric Push and Pull Controller components are combined into a single "basic" Controller:
  • WithExporter() and Start() to configure Push behavior
  • Start() is optional; use Collect() and ForEach() for Pull behavior
  • Start() and Stop() accept Context. (#1378)

Removed

• Remove errUninitializedSpan as its only usage is now obsolete. (#1360)
• Remove Metric export functionality related to quantiles and summary data points: this is not specified (#1412)
• Remove DDSketch metric aggregator; our intention is to re-introduce this as an option of the histogram aggregator after new OTLP histogram data types are released (#1412)

Fixed

• BatchSpanProcessor.Shutdown() will now shutdown underlying export.SpanExporter. (#1443)

Changelog

Sourced from go.opentelemetry.io/otel/log's changelog.

[1.40.0/0.62.0/0.16.0] 2026-02-02

Added

• Add AlwaysRecord sampler in go.opentelemetry.io/otel/sdk/trace. (#7724)
• Add Enabled method to all synchronous instrument interfaces (Float64Counter, Float64UpDownCounter, Float64Histogram, Float64Gauge, Int64Counter, Int64UpDownCounter, Int64Histogram, Int64Gauge,) in go.opentelemetry.io/otel/metric. This stabilizes the synchronous instrument enabled feature, allowing users to check if an instrument will process measurements before performing computationally expensive operations. (#7763)
• Add go.opentelemetry.io/otel/semconv/v1.39.0 package. The package contains semantic conventions from the v1.39.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.38.0. (#7783, #7789)

Changed

• Improve the concurrent performance of HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar by 4x. (#7443)
• Improve the concurrent performance of FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar. (#7447)
• Improve performance of concurrent histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7474)
• Improve performance of concurrent synchronous gauge measurements in go.opentelemetry.io/otel/sdk/metric. (#7478)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/stdout/stdoutmetric. (#7492)
• Exporter in go.opentelemetry.io/otel/exporters/prometheus ignores metrics with the scope go.opentelemetry.io/contrib/bridges/prometheus. This prevents scrape failures when the Prometheus exporter is misconfigured to get data from the Prometheus bridge. (#7688)
• Improve performance of concurrent exponential histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7702)
• The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)
• The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)

Fixed

• Fix bad log message when key-value pairs are dropped because of key duplication in go.opentelemetry.io/otel/sdk/log. (#7662)
• Fix DroppedAttributes on Record in go.opentelemetry.io/otel/sdk/log to not count the non-attribute key-value pairs dropped because of key duplication. (#7662)
• Fix SetAttributes on Record in go.opentelemetry.io/otel/sdk/log to not log that attributes are dropped when they are actually not dropped. (#7662)
• Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to correctly handle HTTP/2 GOAWAY frame. (#7794)
• WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for ioreg command on Darwin (macOS). (#7818)

Deprecated

• Deprecate go.opentelemetry.io/otel/exporters/zipkin. For more information, see the OTel blog post deprecating the Zipkin exporter. (#7670)
