[1.43.0/0.65.0/0.19.0] 2026-04-02

Added

• Add IsRandom and WithRandom on TraceFlags, and IsRandom on SpanContext in go.opentelemetry.io/otel/trace for W3C Trace Context Level 2 Random Trace ID Flag support. (#8012)
• Add service detection with WithService in go.opentelemetry.io/otel/sdk/resource. (#7642)
• Add DefaultWithContext and EnvironmentWithContext in go.opentelemetry.io/otel/sdk/resource to support plumbing context.Context through default and environment detectors. (#8051)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#8038)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc. (#8038)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#8038)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#8038)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp. (#8038)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8038)
• Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8038)
• Add support for per-series start time tracking for cumulative metrics in go.opentelemetry.io/otel/sdk/metric. Set OTEL_GO_X_PER_SERIES_START_TIMESTAMPS=true to enable. (#8060)
• Add WithCardinalityLimitSelector for metric reader for configuring cardinality limits specific to the instrument kind. (#7855)

Changed

• Introduce the EMPTY Type in go.opentelemetry.io/otel/attribute to reflect that an empty value is now a valid value, with INVALID remaining as a deprecated alias of EMPTY. (#8038)
• Improve slice handling in go.opentelemetry.io/otel/attribute to optimize short slice values with fixed-size fast paths. (#8039)
• Improve performance of span metric recording in go.opentelemetry.io/otel/sdk/trace by returning early if self-observability is not enabled. (#8067)
• Improve formatting of metric data diffs in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8073)

Deprecated

• Deprecate INVALID in go.opentelemetry.io/otel/attribute. Use EMPTY instead. (#8038)

Fixed

• Return spec-compliant TraceIdRatioBased description. This is a breaking behavioral change, but it is necessary to make the implementation spec-compliant. (#8027)
• Fix a race condition in go.opentelemetry.io/otel/sdk/metric where the lastvalue aggregation could collect the value 0 even when no zero-value measurements were recorded. (#8056)
• Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to mitigate excessive memory usage caused by a misconfigured or malicious server. Responses exceeding the limit are treated as non-retryable errors. (#8108)
• Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp to mitigate excessive memory usage caused by a misconfigured or malicious server. Responses exceeding the limit are treated as non-retryable errors. (#8108)
• Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp to mitigate excessive memory usage caused by a misconfigured or malicious server. Responses exceeding the limit are treated as non-retryable errors. (#8108)
• WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for kenv command on BSD. (#8113)
• Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp to correctly handle HTTP2 GOAWAY frame. (#8096)

[1.42.0/0.64.0/0.18.0/0.0.16] 2026-03-06

Added

• Add go.opentelemetry.io/otel/semconv/v1.40.0 package. The package contains semantic conventions from the v1.40.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.39.0. (#7985)

@copilot fix the build error

Fixed in c3bf426 and c11fdda. Two issues were resolved:

1. kiota_client_factory_test.go: Changed t.Errorf(err.Error()) → t.Error(err) at lines 45 and 83, which fixes the non-constant format string in call to Errorf vet errors that caused the CI build failure.

2. nethttp_request_adapter.go: Fixed a context leak — prepareContext now returns (context.Context, context.CancelFunc) and all 7 callers (Send, SendEnum, SendCollection, SendEnumCollection, SendPrimitive, SendPrimitiveCollection, SendNoContent) call defer cancel() to properly release the context.WithTimeout cancel function.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• example.com
  • Triggering command: /tmp/go-build168195008/b001/kiota-http-go.test /tmp/go-build168195008/b001/kiota-http-go.test -test.testlogfile=/tmp/go-build168195008/b001/testlog.txt -test.paniconexit0 -test.timeout=10m0s conf�� g_.a --global ux-amd64/pkg/tool/linux_amd64/vet user.name mbedded (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
