I still have some 3.6 BMs running in my hierarchy. We always used the same
proxy.nlm on all 3.X BMs in the tree.

Today i tried out the 3.8 BMs and got some public errors. Anyone knows a
workaround (change more than just the proxy.nlm) or at least know why this
was changed? There are quite a few 3.6 BM issues which are only solved by
using 3.7 proxy NLMs and thats also recommend in some TiDs.
