 ## What's new
 
 - **MOSS-Transcribe-Diarize** brings long-form ASR, timestamps, and anonymous speaker labels to FunASR services, Docker, Kubernetes, vLLM/SGLang workflows, and FunClip. [Deploy MOSS ->](./docs/moss_transcribe_diarize.md)
-- **FunASR 1.4.20** preserves the original optional speaker dependency failure in a chained `ImportError` when `spk_model` is requested, while ASR-only construction remains available. [Fix #3819](https://github.com/modelscope/FunASR/pull/3819). Install with `python -m pip install -U "funasr==1.4.20"`. [Release and verification scope ->](https://github.com/modelscope/FunASR/releases/tag/v1.4.20)
+- **FunASR 1.4.21** preserves the streaming punctuation cache on empty or whitespace chunks, returning an empty result without touching cached words or the embedding path; nonempty inference is unchanged. [Fix #3824](https://github.com/modelscope/FunASR/pull/3824). Install with `python -m pip install -U "funasr==1.4.21"`.

   **FunASR 1.4.19** handles empty-token Paraformer batches, enforces `max_speakers` for automatic clustering, and adds validated JSON-object `--hf_overrides` support to realtime WebSocket serving. [Release and verification scope ->](https://github.com/modelscope/FunASR/releases/tag/v1.4.19)
   Previous release **FunASR 1.4.18** fixes cross-script hotword misreplacement, filtered-token timestamp alignment, and Chinese VAD sentence/speaker drift. [Release and verification scope ->](https://github.com/modelscope/FunASR/releases/tag/v1.4.18)
   **Earlier release: FunASR 1.4.17** adds explicit PCM16 input and improves timestamp, hotword, speaker-sample-rate, and long-segment streaming handling. [Release and verification scope ->](https://github.com/modelscope/FunASR/releases/tag/v1.4.17)
