 - We improved the "Possible duplicate entries" window to remember its size and position throughout a session. [#6582](https://github.com/JabRef/jabref/issues/6582)
 - We divided the toolbar into small parts, so if the application window is to small, only a part of the toolbar is moved into the chevron popup. [#6682](https://github.com/JabRef/jabref/pull/6682)
 - We changed the layout for of the buttons in the Open Office side panel to ensure that the button text is always visible, specially when resizing. [#6639](https://github.com/JabRef/jabref/issues/6639)
+- We merged the two new library commands in the file menu to one which always creates a new library in the default library mode. [#6359](https://github.com/JabRef/jabref/pull/6539#issuecomment-641056536)
