[NTG-context] german hyphenation patterns

Hi out there, I'am not sure if this is a ConTeXt problem (I doubt it slightly) but I am a bit confused: How can I activate german hyphenation patterns? I have used \mainlanguage[de] in my document and it was OK some time ago. Meanwhile I have updated ConTeXt and my TeX (current texlive). Where should I start to check? The output of my context run is: [...] language : language en is active [...] bodyfont : 12pt rm is loaded language : patterns 2:2-en-2 loaded specials : fdf,tpd loaded Patrick -- You are your own rainbow!
