As Eloy Lafuente noticed in the tracker discussion, we display the information about the current version in the browser window title but not at the screen itself. The patch fixes that by displaying the information in the page heading instead of the page title. Eloy's original idea to put the information into the grey message box would require a change of [upgradesure,core_admin] string because unfortunately it does not expect $a as an object but as a plain string.
