Hello, yesterday I upgraded my debian and I found out that my previsously prepared publication cannot be compiled with the new version of ConTeXt. The publication looks like: * main file "ausgewaehlte.tex" \startproject ausgewaehlte \environment ausgewaehlte_environment \startfrontmatter \setuppagenumbering[state=stop] \product titelpage \stopfrontmatter \startbodymatter \setuppagenumbering[state=start] \product first \product second ... \stopbodymatter \stopproject * environment file "ausgewaehlte_environment.tex" \startenvironment ausgewaehlte_environment \usemodule[typo-krn] \usemodule[letterspace] \setupoutput[pdftex] \enableregime[utf] \mainlanguage[cz] \definefontfeature[hz][default][protrusion=punctuation,expansion=quality, mode=node] \definefontfeature[oldnumbers][language=DFLT,script=latn,onum=yes] \setupfonthandling [hz][min=20, max=20, step=5] \setupalign[hz,hanging] ... ... \stopenvironment This publication I could compile without problem with context having these debian packages: luatex 0.70.1-1+b1 next generation TeX engine texlive-luatex 2009-15 TeX Live: LuaTeX packages context 2011.05.18.20110627-1 powerful TeX format context-modules 20110701-1 additional ConTeXt modules After upgrading debian to: luatex 0.70.1.20120524-3 amd64 next generation TeX engine texlive-luatex 2012.20120611-4 all TeX Live: LuaTeX packages context 2012.05.30.20120611-1 all powerful TeX format context-modules 20120611-1 all additional ConTeXt modules I get these error by compiling the above source: This is LuaTeX, Version beta-0.70.2-2012070300 (TeX Live 2012/Debian) \write18 enabled.

Why the new context version complains about "duplicate core namespace" when the previous version worked without problems? Any help will be appreciated. Best regards Pavel
