Changelog

Sourced from go.opentelemetry.io/contrib/exporters/autoexport's changelog.

[1.47.0/2.6.0/0.72.0/0.38.0/0.27.0/0.21.0/0.17.0/0.19.0] - 2026-10-03

Added

• Add NewResourceDetectorWithOptions and the WithAWSLogger option to go.opentelemetry.io/contrib/detectors/aws/ec2/v2, allowing a custom AWS SDK logging.Logger to be supplied to the EC2 resource detector. (#9132)
• Add go.opentelemetry.io/contrib/detectors/openshift, a new resource detector for OpenShift 4 clusters, ported from processor/resourcedetectionprocessor/internal/openshift in opentelemetry-collector-contrib. Detects k8s.cluster.name, and cloud.provider, cloud.platform and cloud.region for clusters running on AWS, Google Cloud and IBM Cloud; Azure clusters report cloud.provider and cloud.platform only. (#9499)
• Add go.opentelemetry.io/contrib/detectors/kubeadm, a new resource detector for kubeadm-provisioned Kubernetes clusters, ported from processor/resourcedetectionprocessor/internal/kubeadm in opentelemetry-collector-contrib. Detects k8s.cluster.name from the ClusterConfiguration document in the kube-system/kubeadm-config ConfigMap and k8s.cluster.uid from the kube-system namespace UID. (#9500)

Changed

• Client metrics in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp no longer include attributes from the server-side Labeler, preventing attributes such as http.route from leaking into outbound requests. This is a breaking change for applications that use ContextWithLabeler to add custom client metric attributes: use ContextWithClientLabeler / ClientLabelerFromContext or the WithMetricAttributesFn option instead. Server-side use of ContextWithLabeler / LabelerFromContext is unchanged. (#8924)
• Stop emitting the legacy http.read_bytes and http.wrote_bytes attributes on the per-operation span events enabled by WithMessageEvents in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. The read and write events remain, while total body sizes continue to be recorded on the server span as http.request.body.size and http.response.body.size according to HTTP semantic conventions. (#9624)

Deprecated

• Deprecate go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws. (#9707)
• Deprecate go.opentelemetry.io/contrib/propagators/aws. (#9706)
• Deprecate go.opentelemetry.io/contrib/samplers/probability/consistent. (#9633)
• Deprecate ReadBytesKey, ReadErrorKey, WroteBytesKey, and WriteErrorKey in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. The identifiers remain available and their values are unchanged, but WithMessageEvents no longer emits http.read_bytes or http.wrote_bytes. There is no semantic-convention replacement for per-read or per-write byte counts or the human-readable error fields. Use HTTPRequestBodySizeKey and HTTPResponseBodySizeKey from go.opentelemetry.io/otel/semconv/v1.43.0 to record total body sizes on the span. If an error causes the HTTP request to fail, set the span status to Error and record ErrorType(err) from go.opentelemetry.io/otel/semconv/v1.43.0 on the span. (#9624)

Fixed

• Treat empty Prometheus exporter environment variable values as unset in go.opentelemetry.io/contrib/exporters/autoexport, restoring the documented defaults. (#9636)
• Bound converter-owned recursive map, slice, array, and pointer traversal in go.opentelemetry.io/contrib/bridges/otellogr, go.opentelemetry.io/contrib/bridges/otellogrus, go.opentelemetry.io/contrib/bridges/otelslog, and go.opentelemetry.io/contrib/bridges/otelzap. A field requiring more than 100 such levels is replaced with <max-depth-exceeded> and the record continues to be emitted. Existing fmt and user-method behavior remains unchanged. (#9691)
• Format span attributes in go.opentelemetry.io/contrib/zpages using attribute.Value.String instead of the deprecated attribute.Value.Emit, following the OpenTelemetry AnyValue representation for non-OTLP protocols. (#9453)
• Set error.type on the span and on the request-duration, request-body-size, and response-body-size metrics when a client disconnects mid-request in go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin, using the request context's cancellation error as the classification source when the handler has not already recorded an error via c.Error. Previously a disconnect was recorded with span status Error and no error.type, indistinguishable from a genuine server fault. (#9394)
• Report Prometheus metrics HTTP server errors in go.opentelemetry.io/contrib/otelconf when using the v0.2.0 configuration schema. The error check was inverted, so a clean shutdown (http.ErrServerClosed) was reported as unexpected while real Serve errors were ignored. (#9653)
• Fix temporary file cleanup for multipart requests in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp by copying the parsed multipart form back to the original request during deferred cleanup, preserving net/http cleanup during panic unwinding for HTTP/2 panic handling and outer recovery middleware paths. Unrecovered HTTP/1 handler panics remain uncleaned because net/http skips finishRequest in that path. (#9685)
• Fix http.client.request.body.size recording for streaming request bodies in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#8684)
• Bound Kubernetes ConfigMap requests in go.opentelemetry.io/contrib/detectors/aws/eks with a 10-second timeout so Detect cannot hang indefinitely when the caller-provided context has no deadline. (#9419)

Removed

• Drop support for [Go 1.25]. (#9584)
• Remove go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho. Use github.com/labstack/echo-opentelemetry instead. (#9613)

[1.46.0/2.5.3/0.71.0/0.37.3/0.26.0/0.20.1/0.16.3/0.18.0] - 2026-08-25

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

• Report ot-baggage-* extraction errors from go.opentelemetry.io/contrib/propagators/ot to otel.Handle instead of silently discarding them, while still attaching the successfully parsed baggage members to the context. (#9395)
• Set error.type on the rpc.client.call.duration and rpc.server.call.duration metrics in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc when the RPC fails with a non-OK status, per the RPC semantic conventions. (#9429)
• Reject OTLP exporter headers with an empty name in go.opentelemetry.io/contrib/otelconf, go.opentelemetry.io/contrib/otelconf/x, and go.opentelemetry.io/contrib/otelconf/v0.3.0, instead of forwarding invalid header names to OTLP exporters. (#9102)

• Add the experimental Finisher synchronous metric instrument extension interface to go.opentelemetry.io/otel/metric/x. (#8906)

Changed

• Use the OpenTelemetry Attribute Collection representation for non-OTLP protocols for metric data diffs in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8993)
• Apply a maximum depth of 64 by default to span, event, link, log record, and instrumentation scope attribute values in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log. (#8938)

• Fix a data race in NewPeriodicReader where r.inst was assigned after the background goroutine was launched in go.opentelemetry.io/otel/sdk/metric. (#9028)
• Prevent precision loss for large int64 values in Sum, Histogram, and ExponentialHistogram aggregations in go.opentelemetry.io/otel/sdk/metric. (#8981)
• Ensure grpc.DialOption values passed via WithDialOption take precedence over conflicting internally-computed defaults in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc, and go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#8805, #8834, #8836)
• Treat overflowing OTEL_METRIC_EXPORT_INTERVAL and OTEL_METRIC_EXPORT_TIMEOUT values as invalid in go.opentelemetry.io/otel/sdk/metric. (#8800)
• Prevent a panic in NewFixedSizeReservoir and FixedSizeReservoirProvider when given a negative size in go.opentelemetry.io/otel/sdk/metric/exemplar; negative sizes are now clamped to zero, consistent with a size of zero. (#8832)
• Preserve exponential histogram ZeroThreshold during OTLP metric export in go.opentelemetry.io/otel/exporters/otlp/otlpmetric. (#8801)
• Ensure metric helpers in go.opentelemetry.io/otel/semconv/v1.32.0, go.opentelemetry.io/otel/semconv/v1.33.0, and go.opentelemetry.io/otel/semconv/v1.34.0 record measurements only once when no attributes are provided. (#8849)
• Treat empty OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG values as unset in go.opentelemetry.io/otel/sdk/trace. (#8873)
• Normalize global OTEL_EXPORTER_OTLP_ENDPOINT path joining in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp so trailing-slash base URLs do not produce double-slash log export paths. (#8864)
• Prevent a deadlock when formatting an error passed to RecordError calls back into the span in go.opentelemetry.io/otel/sdk/trace. (#8815)
• Prevent SimpleSpanProcessor.Shutdown from panicking when constructed with a nil exporter in go.opentelemetry.io/otel/sdk/trace. (#8844)

• Truncate string attribute values to empty strings when the configured length limit is zero, including malformed UTF-8, in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/trace, and go.opentelemetry.io/otel/sdk/log. (#9054)
• Fix a data race in NewPeriodicReader where r.inst was assigned after the background goroutine was launched in go.opentelemetry.io/otel/sdk/metric. (#9028)
• Prevent precision loss for large int64 values in Sum, Histogram, and ExponentialHistogram aggregations in go.opentelemetry.io/otel/sdk/metric. (#8981)
• Ensure grpc.DialOption values passed via WithDialOption take precedence over conflicting internally-computed defaults in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc, and go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#8805, #8834, #8836)
• Treat overflowing OTEL_METRIC_EXPORT_INTERVAL and OTEL_METRIC_EXPORT_TIMEOUT values as invalid in go.opentelemetry.io/otel/sdk/metric. (#8800)
• Prevent a panic in NewFixedSizeReservoir and FixedSizeReservoirProvider when given a negative size in go.opentelemetry.io/otel/sdk/metric/exemplar; negative sizes are now clamped to zero, consistent with a size of zero. (#8832)
• Preserve exponential histogram ZeroThreshold during OTLP metric export in go.opentelemetry.io/otel/exporters/otlp/otlpmetric. (#8801)
• Ensure metric helpers in go.opentelemetry.io/otel/semconv/v1.32.0, go.opentelemetry.io/otel/semconv/v1.33.0, and go.opentelemetry.io/otel/semconv/v1.34.0 record measurements only once when no attributes are provided. (#8849)
• Treat empty OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG values as unset in go.opentelemetry.io/otel/sdk/trace. (#8873)
• Normalize global OTEL_EXPORTER_OTLP_ENDPOINT path joining in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp so trailing-slash base URLs do not produce double-slash log export paths. (#8864)
• Prevent a deadlock when formatting an error passed to RecordError calls back into the span in go.opentelemetry.io/otel/sdk/trace. (#8815)
• Prevent SimpleSpanProcessor.Shutdown from panicking when constructed with a nil exporter in go.opentelemetry.io/otel/sdk/trace. (#8844)

Release notes

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

v1.47.0/v0.69.0/v0.23.0/v0.1.0

This release contains the first stable release of the OpenTelemetry Go Logs API and SDK. Our project stability guarantees now apply to the following modules:

• go.opentelemetry.io/otel/log
• go.opentelemetry.io/otel/sdk/log

See our versioning policy for more information about these stability guarantees.

Added

• Add String method for KeyValue type in go.opentelemetry.io/otel/attribute. (#8205)
• Add String method for Set type in go.opentelemetry.io/otel/attribute. (#8347)
• Add WithMaxExportBatchSize to go.opentelemetry.io/otel/sdk/metric to configure the maximum export batch size for PeriodicReader. (#8960)
• Add WithAttributeValueDepthLimit, DefaultAttributeValueDepthLimit, and SpanLimits.AttributeValueDepthLimit in go.opentelemetry.io/otel/sdk/trace to configure the maximum depth of span, event, link, and instrumentation scope attribute values. (#8938)
• Add WithAttributeValueDepthLimit in go.opentelemetry.io/otel/sdk/log to configure the maximum depth of log record and instrumentation scope attribute values. (#8938)
• Add WithMaxResponseSize to 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. (#8941)
• Add experimental ProbabilitySampler in go.opentelemetry.io/otel/sdk/trace/x that conforms to the OpenTelemetry specification's threshold-based sampling algorithm. (#8123)
• Add experimental *Binder extension interfaces in go.opentelemetry.io/otel/metric/x for instruments that support binding attributes ahead of time. (#8760)
• Add the experimental Finisher synchronous metric instrument extension interface to go.opentelemetry.io/otel/metric/x. (#8906)

Changed

• Use the OpenTelemetry Attribute Collection representation for non-OTLP protocols for metric data diffs in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8993)
• Apply a maximum depth of 64 by default to span, event, link, log record, and instrumentation scope attribute values in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log. (#8938)
• Reduce allocations when applying attribute value length limits in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log by rebuilding composite values only when truncation is needed. (#8912)
• Decode traceparent using a hex lookup table in go.opentelemetry.io/otel/propagation, which rejects the specification-disallowed upper-case characters without a separate scan of the header. (#8739)
• Decode all characters at constant indices in TraceIDFromHex and SpanIDFromHex in go.opentelemetry.io/otel/trace to eliminate bounds checks. (#8740)

Fixed

• Count valid U+FFFD replacement characters toward attribute value length limits in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/trace, and go.opentelemetry.io/otel/sdk/log.
