[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)

go.mod is now marked as go 1.25.0, but the repo CI workflow tests/builds with Go 1.24 (see .github/workflows/ci.yml matrix). Go 1.24 will fail to build a module that declares go 1.25.0. Either keep the go directive at 1.24 (if 1.24 remains supported) or update the CI matrix/min supported Go version accordingly.

Suggested change

	go 1.25.0
	go 1.24

The PR title/description says this only bumps go.opentelemetry.io/otel/sdk, but this diff also bumps other dependencies (e.g., github.com/stretchr/testify) and changes the module go version. If these extra updates are intentional/required by the OTel bump, please reflect that in the PR title/description; otherwise consider reverting/splitting unrelated dependency updates to keep the change scoped.
