open-telemetry/opentelemetry-rust (opentelemetry_sdk)

v0.31.0

Compare Source

Released 2025-Sep-25

• Updated opentelemetry and opentelemetry-http dependencies to version 0.31.0.

• Feature: Add span flags support for isRemote property in OTLP exporter (#​3153)

• Updated span and link transformations to properly set flags field (0x100 for local, 0x300 for remote)

• TODO: Placeholder for Span processor related things

  • Fix SpanProcessor::on_start is no longer called on non recording spans

• Fix: Restore true parallel exports in the async-native BatchSpanProcessor by honoring OTEL_BSP_MAX_CONCURRENT_EXPORTS (#​2959). A regression in #​2685 inadvertently awaited the export() future directly in opentelemetry-sdk/src/trace/span_processor_with_async_runtime.rs instead of spawning it on the runtime, forcing all exports to run sequentially.

• Feature: Added Clone implementation to SdkLogger for API consistency with SdkTracer (#​3058).

• Fix: batch size accounting in BatchSpanProcessor when queue is full (#​3089).

• Fix: Resolved dependency issue where the "logs" feature incorrectly
  required the "trace" feature flag
  (#​3096).
  The logs functionality now operates independently, while automatic correlation
  between logs and traces continues to work when the "trace" feature is
  explicitly enabled.
