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)
• Add Err and SetErr on Record in go.opentelemetry.io/otel/log to attach an error and set record exception attributes in go.opentelemetry.io/otel/log/sdk. (#7924)

Changed

• TracerProvider.ForceFlush in go.opentelemetry.io/otel/sdk/trace joins errors together and continues iteration through SpanProcessors as opposed to returning the first encountered error without attempting exports on subsequent SpanProcessors. (#7856)

Fixed

• Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp to correctly handle HTTP2 GOAWAY frame. (#7931)
• Fix semconv v1.39.0 generated metric helpers skipping required attributes when extra attributes were empty. (#7964)
• Preserve W3C TraceFlags bitmask (including the random Trace ID flag) during trace context extraction and injection in go.opentelemetry.io/otel/propagation. (#7834)

Removed

• Drop support for [Go 1.24]. (#7984)
