Hello,

former versions of german.sty (before TeX3) did a dirty trick in fooling
TeX that a new word began anywhere an umlaut was encountered. So there
were more hyphenations than the other way, but of course these were not
always correct. 
Now with TeX3 there came 8-bit and the patterns as well as german.sty
were changed to conform to this new situation.

As far as I know, incorrect hyphenation comes mostly from too long
composite words. Hyphenation of words with umlauts appears correct to
me.

Well, I have used eight bit Times in the example \setupbodyfont[ber,
ptm].

To me it looks like ConTeXt uses the hyphenation patterns in the plain
old TeX 2 way. Too bad I'm not enough of an expert to really figure that
out.
