[Release] openai/openai-agents-python v0.18.2: v0.18.2

OpenAI Agents Python v0.18.2 introduces GPT-5.6 request controls support and hosted multi-agent beta capabilities. The release includes critical fixes for sandbox PTY workers, realtime callback handling, and monotonic playback timing. Multiple refactoring efforts consolidate code for PTY output collection, rclone setup, and retry error handling to improve maintainability.

Key Points

• •GPT-5.6 request controls now supported for enhanced model configuration
• •Hosted multi-agent beta support added for distributed agent deployments
• •Sandbox PTY worker tasks now properly owned to prevent resource leaks
• •Realtime callback errors enqueued synchronously for reliable error handling
• •Monotonic playback timing implemented for consistent realtime audio playback
• •Docker deferred cleanup and Unix PTY file descriptor close tasks properly managed
• •Content-filter refusals from LiteLLM now surfaced instead of empty turns
• •Code consolidation across PTY output collection, rclone setup, and retry logic
• •Model-backed rollout interruptions serialized as dictionaries for consistency
• •Linting rules (G004, RUF012) enabled to improve code quality standards
