Hi,
I was typesetting some German text on a narrow page when I discovered
the justification wasn't as good as expected. I think I tracked this
down to differences in hyphenation points, namely, ConTeXt has fewer:
\starttext
\language[de]
\showhyphens{Zusammenhang}
\showhyphens{anderswo}
\showhyphens{anderswoher}
\stoptext
This shows
languages > hyphenation > show: Zusam[-||]men[-||]hang
languages > hyphenation > show: anderswo
languages > hyphenation > show: anders[-||]wo[-||]her
Now with LaTeX and Babel:
\documentclass{article}
\usepackage[ngerman]{babel}
\begin{document}
\showhyphens{Zusammenhang}
\showhyphens{anderswo}
\showhyphens{anderswoher}
\end{document}
This shows
[] \TU/lmr/m/n/10 Zu-sam-men-hang
[] \TU/lmr/m/n/10 an-ders-wo
[] \TU/lmr/m/n/10 an-ders-wo-her
The LaTeX hyphenation points agree with the German Duden dictionary.
As none of the words use more than 7-bit ASCII, I think newer pattern
changes are not related.
Curiously, the same effect already appears with MKII and MKIV from
TeXLive 2014, the oldest I had around.
I'm also surprised 'anders-wo-her' gets hyphenated but 'anderswo' is
not hyphenated at all.
I could not reproduce a difference with English words so far.
Any ideas? As far as I understand, MKIV/LMTX should use the
de-hyph-1996 patterns which LuaLaTeX uses these days too, via
hyph-utf8.
Thanks,

Babel/ngerman sets left/righthyphenmin to 2/2, but ConTeXt sets those to
3/3 for German. (The English default is 2/3). I don't speak German so I
have no idea which is correct, but you can get the same behaviour in
ConTeXt with:
\mainlanguage[de]
\lefthyphenmin=2
\righthyphenmin=2
\starttext
\showhyphens{Zusammenhang}
\showhyphens{anderswo}
\showhyphens{anderswoher}
\stoptext
which gives:
languages > hyphenation > show: Zu[-||]sam[-||]men[-||]hang
languages > hyphenation > show: an[-||]ders[-||]wo
languages > hyphenation > show: an[-||]ders[-||]wo[-||]her

Perfect, thanks!
Many prefixes have two letters, so changing the default may be
reasonable. But there are more experienced German typographers on
this list who can chime in.

After some research, I found the recommendation in
Forssman, de Jong: Detailtypografie (4. Aufl, 2008, S. 124f.) to
use 2/3 for German justified texts, and 3/4 to 5/5 for ragged text.
They also recommend to never hyphenate words with 5 letters, not sure
that can be encoded.

Hi Leah,
Hans added hyphenmin some time ago:
\setuplanguage[de][lefthyphenmin=2, righthyphenmin=3, hyphenmin=6]
\setuplanguage[deo][lefthyphenmin=2, righthyphenmin=3, hyphenmin=5]
\mainlanguage[de]
\starttext
\startTEXpage[offset=1em]
\hyphenatedword{davon}
\deo\hyphenatedword{davon}
\stopTEXpage
\stoptext
It is technically on the wiki, but it lacks proper “wikification”.
I hope it helps,
Pablo

I just wanted to add it to the hyphenation page on the wiki, but I've seen that you have just added it a couple of days ago. Thanks!

You can use \setuplanguage to change the values.
\setuplanguage
[de]
[ lefthyphenmin=2,
righthyphenmin=2]
