I apologize for not having investigated enough.

However I want to bring up the point that upgrading can be a very
tedious thing. I administer a cluster for which upgrading brings it to a
halt for several hours stopping all calculations going on. At the moment
I have no way to go from 2.1.0 to 2.1.1.

I just want to add this point to the release policy of R which
historically has very quick release cycles which on the one hand is a
very positive thing but on the other hand can be problematic with
respect to some aspects.

Thanks again, Stefan
