4.12.3

Bug Fixes

• anthropic: Fixes an issue where spans were not exported when streamed responses were consumed using get_final_message() or get_final_text().
• code origin for spans: fix a potential memory leak triggered by having code origin for span explicitly disabled via environment variables.
• internal: Fixes an issue on Python 3.9 through 3.12.3 where applications can crash when background worker threads clean up thread-local or context-local data.
• snowflake: Fixes an issue where traced cursor calls fail when command is passed as a keyword argument to execute or executemany.
• profiling: Fixes potential process memory growth when a stack profiling sampling cycle exits before completing a sample.
• profiling: Fixes potential process memory growth in asyncio and gevent workloads after stack profiling sampling cycles exit before completion.
• Fixed an issue that could have caused the internal symbol DB component to restart in nested fork child processes, potentially leading to high memory usage.
• tracing: Fixes an issue where the v0.5 trace API (DD_TRACE_API_VERSION=v0.5) drops traces when a single payload contains between 65,536 and 131,071 unique tag keys and values.
• internal: A memory leak triggered when using @tracer.wrap on functions created at run time has been fixed.
• Code Security: Fixes an issue where applications could crash when asynchronous tasks accessed request data after the originating request completed.
• LLM Observability: Resolves an issue where OpenRouter requests made through the LiteLLM integration produced no span when the OpenAI integration was also enabled.
• profiling: A rare crash happening when using gevent has been fixed.
