 ### Enhancements
 
+* **Adds XLSX document level language detection** Enhancing on top of language detection functionality in previous release, we now support language detection within `.xlsx` file type at Element level.
 * **bump `unstructured-inference` to `0.6.6`** The updated version of `unstructured-inference` makes table extraction in `hi_res` mode configurable to fine tune table extraction performance; it also improves element detection by adding a deduplication post processing step in the `hi_res` partitioning of pdfs and images.
 * **Detect text in HTML Heading Tags as Titles** This will increase the accuracy of hierarchies in HTML documents and provide more accurate element categorization. If text is in an HTML heading tag and is not a list item, address, or narrative text, categorize it as a title.
 * **Update python-based docs** Refactor docs to use the actual unstructured code rather than using the subprocess library to run the cli command itself.

 ### Features 
 
-### Features
+* **XLSX can now reads subtables within one sheet** Problem: Many .xlsx files are not created to be read as one full table per sheet. There are subtables, text and header along with more informations to extract from each sheet. Feature: This `partition_xlsx` now can reads subtable(s) within one .xlsx sheet, along with extracting other title and narrative texts. Importance: This enhance the power of .xlsx reading to not only one table per sheet, allowing user to capture more data tables from the file, if exists.
