v3.13.0

Estimated end-of-life date, accurate to within three months: 08-2026 See the support level definitions for more information.

Deprecation Notes

• tracing: ddtrace.tracer.Pin is deprecated and will be removed in version 4.0.0. To manage configuration of the tracer or integrations please use environment variables.

New Features

• opentelemetry

  • Adds experimental support for exporting logs using the OTLP protocol. To enable this feature install the opentelemetry-otlp-exporter and set DD_LOGS_OTEL_ENABLED=true.
  • Ensures that ddtrace log injection is disabled when OpenTelemetry logs are enabled (DD_LOGS_OTEL_ENABLED=true).

• LLM Observability

  • Adds support for collecting tool definitions, tool calls and tool results in the Amazon Bedrock integration.
  • Adds support for collecting tool definitions, tool calls and tool results in the Google GenAI integration.
  • This introduces support for tool calls and tool results in LLMObs message annotations when using custom instrumentation. The LLMObs.annotate() method now accept input and output data with optional to ol_calls and tool_results fields for function calling scenarios.
  • Adds support for collecting tool definitions, tool calls and tool results in the OpenAI integration.
  • Adds support for collecting tool definitions, tool calls and tool results in the VertexAI integration.

• Django: Added the DD_DJANGO_ALWAYS_CREATE_DATABASE_SPANS config option (default: true).

  When enabled, the Django integration always generates a database span for every operation, even if the underlying database engine is already instrumented. This ensures complete coverage but may produce duplicat e spans and extra overhead.

  When disabled, spans are only created if the database engine is not instrumented.

  To avoid multiple spans per database call, we recommend disabling this option. DD_DJANGO_ALWAYS_CREATE_DATABASE_SPANS=false

• AAP

  • This introduces endpoint discovery for Flask applications. It allows the collection of API endpoints of a Flask application at startup.
  • This introduces endpoint discovery for FastAPI applications. It allows the collection of API endpoints of a FastAPI application at startup.

• Bug Fixes

• AAP: Fixes an issue where security signals would be incorrectly reported on an inferred proxy service instead of the current service.

• CI Visibility: This fix resolves an issue where the pytest plugin would hold a reference to test exceptions beyond the end of the test, preventing them from being garbage-collected and increasing memory usage.

• psycopg: This fix resolves a potential circular import with the psycopg3 contrib.

• internal: This fix resolves an issue where the tracer flare was not sent when DD_TRACE_AGENT_URL was not set, as the default URL was not used.

• tracing

  • Fixes issue with websocket.receive span not closing exactly when another websocket.receive span was opened.
  • Fixes duration of websocket handshake span such that the handshake span closes when the connection is upgraded.
  • Fix where websocket.close parent should be the handshake span when configuration is disabled.
  • Resolves an issue where calling ddtrace.trace.tracer.configure(...) resets the trace writer buffer, causing spans to be dropped.

• Code Security: Fixed a crash in the taint-aware modulo aspect when formatting SQLAlchemy objects whose __repr__ can raise (e.g., inside complex CASE expressions).

• LLM Observability: Properly parse DD_TAGS onto LLM Observability span events' tags.

• sampling

  • Fixed a bug where single span sampling rules were completely ignored when stats computation was enabled, causing all single-sampled spans to be dropped. Note that single span sampling is only used to override trace sampling decisions to keep a span where the trace will be dropped.
  • Removed automatic setting of local trace sampling rule tag (_dd.p.dm=-3) during distributed tracing header extraction.

• ssi, crashtracker: This fix resolves an issue where crashtracker receiver binary was not available in an injected environment.

Other Changes

• LLM Observability: add ability to override the URL origin.
• openai: Removes I/O tags, including llm prompts, parameters, and token usage, from APM spans for OpenAI audio, image, and moderation requests.
