I released version 4.0.3-1 of screen yesterday as test: . There are no prev: or curr: versions of it.
In setup.exe 2.573.2.2, screen is shown in the "Curr" distribution, with an empty description. A little poking around shows that the same thing happens to all packages that have only test releases, with no current or previous-- e.g. emacs-leim, libecpg* . Andrew.
