+- **Async Chunker**: `DoclingServeChunker` now uses `httpx.AsyncClient` instead of sync `requests`
+
+### Fixed
+
+- **OCR Options**: Fixed `DoclingLocalConverter` using base `OcrOptions` class which docling's OCR factory doesn't recognize. Now uses `OcrAutoOptions` for automatic OCR engine selection.
