1.3.0b1 (2026-05-28)

Features Added

• Azure Realtime Native Voice Support: Added AzureRealtimeNativeVoice and
  AzureRealtimeNativeVoiceName, and expanded voice fields to accept Azure realtime native voices.
• WebRTC Call Negotiation Support: Added ClientEventRtcCallSdpCreate, ServerEventRtcCallSdpCreated,
  ServerEventRtcCallError, and RtcCallErrorDetails for SDP-based WebRTC call setup.
• Input Text Streaming Support: Added ClientEventInputTextDelta and ClientEventInputTextDone
  for incrementally streaming text input into existing conversation items.
• Hosted Agent Invocation Input: Added invoke_input to ResponseCreateParams and
  ServerEventResponseInvocationDelta for hosted agent invocation passthrough data.
• Audio Playback Lifecycle Events: Added ServerEventOutputAudioBufferStarted and
  ServerEventOutputAudioBufferStopped to track model audio playback start and stop.
• Echo Cancellation Configuration: Added EchoCancellationReferenceSource and new
  reference_source / channels options on AudioEchoCancellation to support both the default
  server loopback reference path and client-provided stereo echo reference input.
• Smart End-of-Turn Detection: Added SmartEndOfTurnDetection as an audio-based end-of-turn
  detection option.
• Parallel Tool Call Control: Added parallel_tool_calls to session models so callers can
  control whether tool calls may run in parallel.

Breaking Changes

• Image Input Field Rename: Renamed RequestImageContentPart.url to image_url. Update
  image input construction to use image_url= instead of url=.
• Default API Version Update: Changed the SDK default API version from 2026-04-10 to
  2026-06-01-preview. Pass api_version="2026-04-10" explicitly to keep the previous default
  behavior.

Bug Fixes

• Deserialization Improvements: Improved XML model deserialization and common scalar header
  deserialization paths for better compatibility and lower overhead.
