chore(deps): bump go.opentelemetry.io/otel/sdk from 1.39.0 to 1.40.0 in /examples/tracing/golang-push

[dependabot]

Bumps go.opentelemetry.io/otel/sdk from 1.39.0 to 1.40.0.

Changelog

Sourced from go.opentelemetry.io/otel/sdk's changelog.

[1.40.0/0.62.0/0.16.0] 2026-02-02

Added

• Add AlwaysRecord sampler in go.opentelemetry.io/otel/sdk/trace. (#7724)
• Add Enabled method to all synchronous instrument interfaces (Float64Counter, Float64UpDownCounter, Float64Histogram, Float64Gauge, Int64Counter, Int64UpDownCounter, Int64Histogram, Int64Gauge,) in go.opentelemetry.io/otel/metric. This stabilizes the synchronous instrument enabled feature, allowing users to check if an instrument will process measurements before performing computationally expensive operations. (#7763)
• Add go.opentelemetry.io/otel/semconv/v1.39.0 package. The package contains semantic conventions from the v1.39.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.38.0. (#7783, #7789)

Changed

• Improve the concurrent performance of HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar by 4x. (#7443)
• Improve the concurrent performance of FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar. (#7447)
• Improve performance of concurrent histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7474)
• Improve performance of concurrent synchronous gauge measurements in go.opentelemetry.io/otel/sdk/metric. (#7478)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/stdout/stdoutmetric. (#7492)
• Exporter in go.opentelemetry.io/otel/exporters/prometheus ignores metrics with the scope go.opentelemetry.io/contrib/bridges/prometheus. This prevents scrape failures when the Prometheus exporter is misconfigured to get data from the Prometheus bridge. (#7688)
• Improve performance of concurrent exponential histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7702)
• The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)
• The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)

Fixed

• Fix bad log message when key-value pairs are dropped because of key duplication in go.opentelemetry.io/otel/sdk/log. (#7662)
• Fix DroppedAttributes on Record in go.opentelemetry.io/otel/sdk/log to not count the non-attribute key-value pairs dropped because of key duplication. (#7662)
• Fix SetAttributes on Record in go.opentelemetry.io/otel/sdk/log to not log that attributes are dropped when they are actually not dropped. (#7662)
• Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to correctly handle HTTP/2 GOAWAY frame. (#7794)
• WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for ioreg command on Darwin (macOS). (#7818)

Deprecated

• Deprecate go.opentelemetry.io/otel/exporters/zipkin. For more information, see the OTel blog post deprecating the Zipkin exporter. (#7670)

Note

Low Risk
Low risk because this is a dependency version bump limited to an example module; the main risk is minor behavior/compatibility changes from the OpenTelemetry upgrade.

Overview
Updates the examples/tracing/golang-push example’s OpenTelemetry dependencies from v1.39.0 to v1.40.0 (including go.opentelemetry.io/otel, otel/sdk, otel/trace, and indirect otel/metric).

Refreshes go.sum accordingly and bumps indirect golang.org/x/sys to v0.40.0.
