Hi Hans and Taco, I would like to report a problem with the latest release: I just updated my ConTeXt installation and got the following error message: […] This is LuaTeX, Version snapshot-0.25.2-2008041100 (Web2C 7.5.6) (INITEX) (/usr/local/gwTeX/texmf.texlive/tex/context/base/cont-en.tex (/usr/local/gwTeX/texmf.texlive/tex/context/base/context.tex (/usr/local/gwTeX/texmf.texlive/tex/context/base/syst-pln.tex) (/usr/local/gwTeX/texmf.texlive/tex/context/base/syst-prm.tex) ! I can't find file `luat-env.tex'. <to be read again> \relax l.153 \loadmkivfile{luat-env.tex} Please type another input file name: However ConTeXt mkii works fine (ConTeXt ver: 2008.04.16 17:34 MKII fmt: 2008.4.16 int: english/english). My previous version of mkiv used to work fine until ConTeXt version 2008.04.16 11:45. For your information, I am running this on MacBook Pro Intel running MacOS X 10.5.2, and I follow Thomas Schmitz' indications to install LuaTeX. Best regards: OK
