[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 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)

• 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)

PR Review: Dependabot OTel Dependency Bump

Summary: This is a clean dependency update bumping the OpenTelemetry Go SDK from 1.39.0 to 1.43.0, along with several transitive dependency updates. No application logic is changed.

---

What is changing

Direct and transitive OTel updates (1.39.0 to 1.43.0):

• go.opentelemetry.io/otel
• go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp
• go.opentelemetry.io/otel/metric, trace, sdk, sdk/metric

New explicit entries in go.mod: otel/sdk and otel/sdk/metric are now listed explicitly (they were previously implicit transitive deps).

Other dependency bumps (transitive):

• golang.org/x/net: 0.49.0 to 0.52.0
• golang.org/x/sys: 0.40.0 to 0.42.0
• google.golang.org/grpc: 1.77.0 to 1.80.0
• grpc-ecosystem/grpc-gateway/v2: 2.27.3 to 2.28.0
• google.golang.org/genproto: updated to 2026-04-01 snapshot

---

Notable improvements in this upgrade

Security/stability:

• Response body size limit (security): otlptracehttp now limits HTTP response bodies to 4 MiB to prevent excessive memory usage from a misconfigured or malicious OTLP server. Responses exceeding the limit are treated as non-retryable errors. (limit response body size for OTLP HTTP exporters open-telemetry/opentelemetry-go#8108)
• Race condition fix: otel/sdk/metric lastvalue aggregation could incorrectly collect 0 even when no zero-value measurements were recorded. (Fix race in the lastvalue aggregation where 0 could be observed open-telemetry/opentelemetry-go#8056)
• Missing GetBody fix: otlploghttp now correctly handles HTTP/2 GOAWAY frames. (fix: support getBody in otelploghttp open-telemetry/opentelemetry-go#8096)

Issues

Commit message title: The PR title contains a duplicate scope — chore(deps)(deps): — which will fail the commitlint validation enforced in the PR workflow. It should be chore(deps):. This is a Dependabot artifact; you can trigger a rebase with @dependabot rebase which may regenerate the commit, or manually squash/edit the title before merging.

---

Verdict

The dependency updates are safe and bring meaningful fixes, including a security-relevant response size limit and a race condition fix. The only blocker is the malformed commit message title that will fail CI validation.

Recommended action: Fix the commit message title (comment @dependabot rebase to attempt auto-fix, or manually edit), then merge.
