In sources.list on the laptop proposed is disabled now. I think I did not manually change this. So it seems that it got disabled during upgrade. Which would make sense with my second upgrade where I disabled proposed manually before the release upgrade. The weird thing is anyway where those versions come from. Using rmadison they do not show and I thought they should.
