 ### Added
 
+- We added a feature to convert keywords that resemble MSC codes to their descriptions. [#12944](https://github.com/JabRef/jabref/issues/12944)
+- We added a tooltip to keywords that resemble Math Subject Classification(MSC) codes. [#12944](https://github.com/JabRef/jabref/issues/12944)
 - We added a button in Privacy notice and Mr. DLib Privacy settings notice for hiding related tabs. [#11707](https://github.com/JabRef/jabref/issues/11707)
 - We added buttons "Add example entry" and "Import existing PDFs" when a library is empty, making it easier for new users to get started. [#12662](https://github.com/JabRef/jabref/issues/12662)
 - In the Open/LibreOffice integration, we added the provision to modify the bibliography title and its format for CSL styles, in the "Select style" dialog. [#12663](https://github.com/JabRef/jabref/issues/12663)
