• 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)

• 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)

Review: Blocked — requires Go toolchain bump

This Dependabot bump (otltracehttp 1.32.0 → 1.43.0) cannot land as-is. The upstream OpenTelemetry release moved its minimum Go requirement to 1.25.0 starting with v1.42.0:

#34 [test-runner af-cli-builder  5/11] RUN cd control-plane && go mod download
go: go.mod requires go >= 1.25.0 (running go 1.24.13; GOTOOLCHAIN=local)

As a result:

• control-plane/go.mod has been auto-bumped from go 1.24.0 to go 1.25.0.
• Transitive deps (golang.org/x/term v0.41.0, golang.org/x/crypto v0.49.0, golang.org/x/net v0.52.0, golang.org/x/sys v0.42.0, golang.org/x/text v0.35.0) now also require Go ≥ 1.25.
• All build/CI toolchains in the repo still pin Go 1.24:
  • tests/functional/docker/Dockerfile.test-runner — FROM golang:1.24-bookworm
  • deployments/docker/Dockerfile.control-plane — FROM golang:1.24-bookworm
  • deployments/docker/Dockerfile.demo-go-agent — FROM golang:1.24-alpine
  • deployments/docker/Dockerfile.go-agent — FROM golang:1.24-alpine
  • .github/workflows/control-plane.yml — go-version: '1.24.2' (×2)
  • .github/workflows/coverage.yml — go-version: '1.24.2'

Both Functional Tests (local) and Functional Tests (postgres) fail for this reason, and so does control-plane-image.

Options

1. Recommended (minimal): Pin this bump to v1.41.0 — the last otltracehttp release compatible with Go 1.24 — to stay on the existing toolchain. This matches the other otel modules already at 1.40/1.41 on main.
2. Alternative (broader): Do a coordinated Go 1.25 bump across every Dockerfile and CI workflow listed above, then accept the 1.43.0 otel bump. That's out of scope for a Dependabot PR and should be a separate, reviewed change.

I'd suggest closing this PR and letting Dependabot recreate it (or configure a 1.25-blocking ignore rule) once either path is chosen. Not force-pushing a fix since this is substantive/architectural per review guidelines.

Approving: bumps Go to 1.25 and otel to v1.43.0 to close security alerts #121 and #122. CI is green.
