Until for two days ago I have manage to d-u every or every second day without loosing any packages that where not changed to new versions ( I know that it's not safe anyway, as this thread says) but since the last two days there is one package that is going away and no new one is coming, it's libavfilter5. Sometimes there are packages that are not needed anymore, is that the case for libavfilter5? If not, I will wait.
