As far as I can tell, this happens for any package.
Perhaps I should also clarify: when I wrote "the status of the selected package is not changed" in my original report above, what I mean is that the gui of Synaptic indicates that the status of the package is not changed (i.e. not locked or pinned). I haven't yet been able to observe whether Synaptic actually treats the package as pinned when a new version of the package becomes available.
