posthog-v7.75.11

Patch changes

• 04e6a4c Privacy mode now covers error text and the remaining content paths in the AI integrations.

  • $ai_error no longer carries the exception message when privacy mode is on. Provider errors and validation errors often quote the prompt or the model output, so the SDK now sends a summary built only from structured fields: the class name, HTTP status, provider error code, param, request ID and the class names of chained causes (for example BadRequestError: 400 invalid_request_error param=messages[3].content request_id=req_123). This applies to the OpenAI, Anthropic and Gemini wrappers (including Gemini embeddings), LangChain generations, spans and traces, and OpenAI Agents spans.
  • The LangChain callback handler no longer sends an $exception event for a failed run when privacy mode is on.
  • $ai_tools masks the headers and authorization of MCP tool definitions (type: "mcp") with [REDACTED], with or without privacy mode. The tools you pass in are not modified.
  • Gemini: a per-call posthog_privacy_mode=False no longer turns off privacy mode set on the client, matching the OpenAI and Anthropic wrappers.
  • OpenAI Agents: privacy mode now redacts $ai_trace_metadata and the prompt and instructions in transcription and speech span model_config.
  • OpenTelemetry: PostHogSpanProcessor and PostHogTraceExporter accept privacy_mode and client, and also honor the client's (or the module-level) privacy_mode. When on, exported spans drop prompt, completion, tool argument and tool result attributes, non-exception span events, exception messages and stack traces, and the span status description. — Thanks @carlos-marchal-ph!
