The Python SDKs pivoted toward efficient real-time data streaming and tighter protocol integration. Data tracks shipped in rtc-v1.1.4, enabling arbitrary binary streams alongside audio and video, while protocol-v1.1.5 added participant state tracking (joined_at, state fields) and agent development support via IPC. Performance work landed across both versions—lazy FFI loading deferred native library initialization, event filtering reduced memory allocations in the subscription pipeline, and frame handling was optimized to eliminate unnecessary copies and normalize memoryview formats to bytes.
