+- Added support for streaming intermediate results from async function calls. Call `result_callback` multiple times with `properties=FunctionCallResultProperties(is_final=False)` to push incremental updates, then call it once more (with `is_final=True`, the default) to deliver the final result. Only valid for functions registered with `cancel_on_interruption=False`.

+- Fixed duplicate LLM replies that could occur when multiple async function call results arrived while an LLM request was already queued.
