 ### Fixes
 
+* **`partition()` now forwards `strategy` arg to `partition_docx()` and `partition_pptx()`.** A `strategy` argument passed to `partition()` (or the default value "auto" assigned by `partition()`) is now forwarded to `partition_docx()` and `partition_pptx()` when those filetypes are detected.
