[1.45.0/2.5.2/0.70.0/0.37.2/0.25.0/0.20.0/0.16.2/0.17.0] - 2026-08-03

Added

• Add go.opentelemetry.io/contrib/detectors/ibmcloud/vpc, a new resource detector for IBM Cloud VPC virtual server instances, ported from github.com/open-telemetry/opentelemetry-collector-contrib/processor/resourcedetectionprocessor/internal/ibmcloud/vpc. Detects cloud.provider, cloud.platform, cloud.region, cloud.availability_zone, cloud.account.id, cloud.resource_id, host.id, host.image.id, host.image.name, host.name, and host.type. (#9011)
• Add go.opentelemetry.io/contrib/detectors/k8sapi, a new resource detector that queries the Kubernetes API. Detects k8s.node.name and k8s.node.uid when K8S_NODE_NAME is set via the downward API, and k8s.cluster.uid derived from the kube-system namespace UID (works on any Kubernetes distribution). (#9108)
• Add new elasticbeanstalk resource detector for AWS Elastic Beanstalk, ported from processor/resourcedetectionprocessor/internal/aws/elasticbeanstalk in opentelemetry-collector-contrib. (#8993)
• The resource created by go.opentelemetry.io/contrib/otelconf now includes default SDK attributes. (#8990)
• Add support for the aws.ecs resource detector in go.opentelemetry.io/contrib/otelconf/x. (#8915)
• Add support for the aws.eks resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9138)
• Add support for the azure.vm resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9074)
• Add support for the gcp resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9137)
• Add go.opentelemetry.io/contrib/detectors/azure/azureappservice, a new resource detector for Azure App Service. Detects cloud.*, service.name, azure.resource_group.name, azure.app_service.instance.id, and deployment.environment.name from the WEBSITE_* and REGION_NAME environment variables. (#9289)
• Add azurecontainerapps resource detector for Azure Container Apps. (#8939)
• Add go.opentelemetry.io/contrib/detectors/azure/azurefunctions, a new resource detector for Azure Functions. Detects cloud.*, service.name, azure.resource_group.name, faas.instance, and deployment.environment.name from the FUNCTIONS_*, WEBSITE_*, CONTAINER_NAME, and REGION_NAME environment variables. (#9290)
• Add NewResourceDetector along with the WithAttributeFilter and WithTagKeyFilter options in go.opentelemetry.io/contrib/detectors/azure/azurevm. WithAttributeFilter restricts the returned resource to the attributes the filter accepts. WithTagKeyFilter opts in to azure.tag.<name> attributes for the VM tags whose keys satisfy the provided predicate; no VM tags are emitted without it. (#9162)
• Add go.opentelemetry.io/contrib/detectors/vultr — a new resource detector for Vultr Cloud Compute instances, ported from processor/resourcedetectionprocessor/internal/vultr in opentelemetry-collector-contrib. Detects cloud.provider, cloud.platform, cloud.region, host.id, and host.name. (#8995)

Changed

• Upgrade go.opentelemetry.io/otel/semconv to v1.43.0, including updates across instrumentation and detector modules. See semantic-conventions v1.43.0 release for complete details. (#9337)
• Upgrade go.opentelemetry.io/otel/semconv to v1.42.0, including updates across instrumentation and detector modules. See semantic-conventions v1.42.0 release for complete details. (#9196)
• Use direct normalized-key lookups in Carrier.Get and Carrier.Keys in go.opentelemetry.io/contrib/propagators/envcar. (#9112)
• Update log bridge conversions to use attribute key-values instead of the removed log key-values 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. (#9180)
• The Version() function in go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux has been replaced by const Version. (#9076)
• Set error.type attribute instead of adding exception span events in go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin. (#8977)
• Prefer the gRPC dial target over the resolved peer IP for the server.address and server.port attributes in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8904)
• The detector in go.opentelemetry.io/contrib/detectors/azure/azurevm now also detects cloud.account.id, cloud.availability_zone, azure.vm.name, azure.vm.size, azure.vm.scaleset.name, and azure.resource_group.name, and prefers osProfile.computerName for host.name (falling back to the VM name), reconciling it with the collector-contrib Azure resource detector. (#9162)

Fixed

• Fix Prometheus reader resource label filter configuration in go.opentelemetry.io/contrib/otelconf/v0.2.0. (#9062)
• Apply resource.detection/development.attributes.included and excluded filtering to resource detector attributes in go.opentelemetry.io/contrib/otelconf/x. (#9131)
• Honor the context configured with WithContext when constructing resources in go.opentelemetry.io/contrib/otelconf and go.opentelemetry.io/contrib/otelconf/x. (#9160)
• Handle nil response bodies from custom RoundTripper implementations in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp without panicking. (#9184)
• Fix incorrect (overestimated) sum calculation for runtime histograms in go.opentelemetry.io/contrib/instrumentation/runtime. (#9063)
• Fix Severity.UnmarshalText round trip for positive FATAL offsets above the named range in go.opentelemetry.io/contrib/processors/minsev. (#9197)
• Reduce binary size by fetching ConfigMaps via rest.HTTPClientFor instead of the Kubernetes clientset in go.opentelemetry.io/contrib/detectors/aws/eks. (#9284)
• TextMapPropagator in go.opentelemetry.io/contrib/propagators/autoprop returns the no-op propagator for empty input, matching the behavior of none. An unknown OTEL_PROPAGATORS value still returns an error with a nil propagator so NewTextMapPropagator falls back to the default TraceContext and Baggage propagators instead of disabling propagation. (#9163)
• Preserve error-valued attributes nested in a group as grouped attributes instead of silently dropping them in go.opentelemetry.io/contrib/bridges/otelslog. (#9238)
• Fix a data race in go.opentelemetry.io/contrib/bridges/otelslog where concurrent Handle calls could corrupt each other's log attributes because kvBuffer.KeyValues returned a slice aliasing a shared buffer. (#9229)
• Avoid a panic in go.opentelemetry.io/contrib/bridges/otelzap when a malformed error field contains a nil or non-error value. (#9068)
• Use azure.container_app.instance.id instead of service.instance.id for the replica name detected by go.opentelemetry.io/contrib/detectors/azure/azurecontainerapps. (#9208)
• Preserve the underlying metadata errors returned with partial resources from go.opentelemetry.io/contrib/detectors/gcp. (#9069)
• Copy MultipartForm back to the request otelmux.Middleware was given after the wrapped handler returns, so net/http can find and remove the temp files ParseMultipartForm created on the context-derived request copy, when otelmux.Middleware wraps a handler directly, in go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux. This does not cover a handler panic, nor the common router.Use(...) integration, where gorilla/mux's own routing step makes an additional request copy the middleware cannot write back through; see gorilla/mux#777. (#9361)
• Report the b3 header from Fields() for the default B3Unspecified single-header injection encoding, matching what Inject writes, in go.opentelemetry.io/contrib/propagators/b3. (#9273)
• Fix go.opentelemetry.io/contrib/propagators/aws/xray producing deterministic trace and span IDs when the seed read from crypto/rand silently failed, by switching to math/rand/v2's concurrency-safe top-level generator. (#9359)
• Strip connection number suffix from connection ID in go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/v2/mongo/otelmongo to prevent unbounded metric cardinality. (#9352)

• Fix go.opentelemetry.io/contrib/propagators/aws/xray producing deterministic trace and span IDs when the seed read from crypto/rand silently failed, by switching to math/rand/v2's concurrency-safe top-level generator. (#9359)
• Strip connection number suffix from connection ID in go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/v2/mongo/otelmongo to prevent unbounded metric cardinality. (#9352)

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)
