AI Chat Release Notes

tag-20260723-v1 (2026-07-23)

Upgraded the TiRTC Go SDK to v0.3.10, fixing AI Chat command-word rewriting so the fixed command word 0x2100 is sent and received unchanged.

Added TiRTC uplink support for H.264 and H.265 video frames, enabling visual context for agents with image understanding.
Coze server events are now delivered through JSON-RPC forward with the original Coze event preserved, except conversation.audio.delta, which remains on the audio channel.
Standardized Coze and Qwen third-party agent audio to 20 ms PCM frames for more stable streaming playback, and stopped sending empty Qwen voice settings.
Final ASR captions now explicitly return is_final=true.
device_id and role_id in start_session must match the signed parameters in the connection credential.

Improved TiRTC Opus downlink handling by encoding and sending continuous 20 ms frames for better playback compatibility.

First public release.
