in muon 1.3.1 there is no option in the view menu to display columns that show the version of the current installed package or the upgrade version. The option to show this to the user so that they will know if the possible update is major or minor should at least be allowed. The version could also be shown in the extra information thing that pops up from the bottom of the window when a package is selected instead of a column. It would be more useful than simply saying "the list of changes is not yet available".
