Compare Source

Patch Changes

• 0bc8d4f: Fix chat onFinish handling when overlapping requests clear the active response before a resume stream finishes.

v7.0.27

Compare Source

Patch Changes

• ac01b79: Allow validating assistant UI messages with empty parts so persisted errored responses remain loadable.
• 2696562: experimental_streamTranscribe result promises now resolve without consuming fullStream: accessing any result promise consumes the stream internally. Previously await result.text alone deadlocked on transform backpressure. Because live transcription streams can be unbounded, fullStream is explicitly single-consumer (no replay buffering): access it once, before any result promise, when both stream parts and final results are needed.
