[luk384090-cloud]

🎉 DashScope Java SDK v2.23.6 is here

We've shipped v2.23.6, headlined by a brand-new Qwen Live SDK for building realtime voice conversations with Qwen over WebSocket. This release also brings base64 audio input to Voice Enrollment and fixes edge cases in WebSocket close handling.

🚀 New: Qwen Live SDK — realtime WebSocket conversation API (#290)

The entry point is QwenLiveConversation, which manages a single-connection WebSocket lifecycle with full session management: connect(), close(), cancel(), and awaitSessionClosed().

Core classes in com.alibaba.dashscope.audio.live:

• QwenLiveConversation — WebSocket session lifecycle and session management
• QwenLiveConnectionParam — connection configuration (API key, model, endpoint); supports the DASHSCOPE_WEBSOCKET_QWEN_LIVE_BASE_URL environment override
• QwenLiveSessionConfig — session-level configuration such as turn detection and input/output modalities
• QwenLiveResponsesConfig — model response configuration
• QwenLiveCallback / QwenLiveCallbackDispatcher — unified event callbacks with optional ordered async dispatch
• QwenLiveContext / QwenLiveContextCompaction — context and context compaction support
• QwenLiveDelegation / QwenLiveDelegationType — client and responses delegation

Key features:

• byte[] audio input for low-latency streaming
• Unified onError callback with optional ordered async dispatch
• Guaranteed single onClose callback — transport failures during close now deliver the requested close code correctly
• Dedicated WebSocket endpoint, no longer sharing the Omni base URL

🎧 Voice Enrollment — base64 audio support

VoiceEnrollmentService now accepts base64-encoded audio for voice cloning, in addition to the existing audio formats — convenient for serverless and HTTP-only environments.

🐛 Bug fixes

• close() now always completes with exactly one onClose callback; socket cancellation during close-frame rejection no longer causes missed callbacks
• Transport failures during a pending close now correctly deliver the requested close code instead of being silently dropped

🧪 Samples

• QwenLiveQuickStart.java
• QwenLiveUsage.java
