What's Changed

  • fix(mcp): fall back to HTTP headers for server-side trace context when params._meta is absent (#829)
  • fix(mcp-instrumentation): always inject W3C trace context into outbound HTTP request headers so MCP servers that read context only from HTTP (API Gateways, service meshes, non-Python MCP servers) can join the caller's trace, even with OTEL_MCP_SUPPRESS_HTTP_INSTRUMENTATION enabled (#827)
  • Nightly dependency update: OpenTelemetry 1.44.0/0.65b0 (#799)
  • feat(genai): capture user input and agent output on llama_index invoke_agent spans (#824)
  • fix(crewai): use native per-call token usage when crewai provides it (#822)
  • fix(crewai): normalize tool description across crewai versions (#821)
  • fix(serviceevents): key the incident-snapshot dedup hash on operation + bounded throw-site origin (module/path.function) (#825)
  • fix(crewai): report per-call LLM token usage instead of cumulative total (#806)
  • fix(genai): serialize tool call arguments/results and blob bytes to match OTel util-genai (primitives kept native, bytes base64-encoded) (#817)
  • feat(genai): capture user input and agent output on invoke_agent spans (#815)
  • refactor(serviceevents): make the endpoint span processor framework-agnostic
  • fix(serviceevents): gate incident trace correlation on the SAMPLED flag and harden incident dedup/rate-limiting
  • fix(genai): serialize list-valued message content into typed parts so multimodal/reasoning content is no longer stringified to a Python repr in gen_ai.input/output.messages across langchain, llama_index, and crewai (#805)
  • feat: add OTel lite SDK for Lambda cold start optimization (#789)
