[Release] openai/openai-agents-python v0.19.2: v0.19.2

OpenAI Agents Python v0.19.2 is a maintenance release focused on bug fixes and stability improvements across multiple subsystems. Key improvements include exposing original callables through wrappers, fixing guardrail result reporting, enhancing MCP credential redaction for security, improving memory session item counting, and resolving voice/audio dispatcher issues. The release also addresses sandbox environment preservation, modal path validation, realtime event payload handling, and tracing deadline management.

Key Points

• •Expose original callable through wrapped decorators for better introspection and debugging
• •Report input guardrail results when tripwire aborts run to ensure security feedback is captured
• •Consolidate exception re-raises using bare raise statements across all modules for cleaner error handling
• •Redact MCP URL credentials from SDK errors, tracing, tool metadata, and transport errors to prevent credential leakage
• •Fix memory session item counting for SQLAlchemy, MongoDB, Redis, Dapr, and AdvancedSqlite with positive limits
• •Enforce closed state in Redis and Dapr sessions to prevent resource leaks
• •Preserve raw server event payloads in realtime subsystem for accurate event processing
• •Fix voice audio dispatcher to block while idle and properly handle session_ended signals
• •Use monotonic export deadlines in tracing to ensure reliable timeout handling
• •Clean failed MCP servers before reconnecting and preserve completed LiteLLM streams on cleanup failure
