Deprecation Notes

• Tracing: DD_TRACE_INFERRED_SPANS_ENABLED is deprecated and will be removed in 5.0.0. Use DD_TRACE_INFERRED_PROXY_SERVICES_ENABLED instead. The old environment variable continues to work but emits a DDTraceDeprecationWarning when set.

Bug Fixes

• LLM Observability: This fix resolves an issue where text wrapped in Bedrock Converse guardContent content blocks was rendered as [Unsupported content type: guardContent] in traces, dropping the user's input.

• LLM Observability: The OpenAI integration now preserves assistant message content when tool_calls are present on the same message. #17760

• starlette: This fix resolves an issue where passing middleware=None caused application startup to fail when Starlette tracing was enabled.

• LLM Observability: Resolves an issue in the Claude Agent SDK integration where unnecessary LLM spans were being created and affecting the trace structure. The handler now only opens a new LLM span after a UserMessage that actually contained tool results, so messages without tool results no longer overwrite the in-flight LLM span.
