 ### Changed
 
+- We changed the resize behavior of table columns to have smart fit into the table if there is enough space. [#967](https://github.com/JabRef/jabref/issues/967)
 - The export to MS Office XML now exports the author field as `Inventor` if the bibtex entry type is `patent` [#7830](https://github.com/JabRef/jabref/issues/7830)
 - We changed the EndNote importer to import the field `label` to the corresponding bibtex field `endnote-label` [forum#2734](https://discourse.jabref.org/t/importing-endnote-label-field-to-jabref-from-xml-file/2734)
 - The keywords added via "Manage content selectors" are now displayed in alphabetical order. [#3791](https://github.com/JabRef/jabref/issues/3791)

 - We changed the way JabRef displays the title of a tab and of the window. [4161](https://github.com/JabRef/jabref/issues/4161)
 - We changed connect timeouts for server requests to 30 seconds in general and 5 seconds for GROBID server (special) and improved user notifications on connection issues. [7026](https://github.com/JabRef/jabref/pull/7026)
 - We changed the order of the library tab context menu items. [#7171](https://github.com/JabRef/jabref/issues/7171)
+- We renamed "Show extra columns" to "Show dedicated file columns". [#7181](https://github.com/JabRef/jabref/pull/7181)
 - We changed the way linked files are opened on Linux to use the native openFile method, compatible with confined  packages. [7037](https://github.com/JabRef/jabref/pull/7037)
 - We refined the entry preview to show the full names of authors and editors, to list the editor only if no author is present, have the year earlier. [#7083](https://github.com/JabRef/jabref/issues/7083)
