Hi, with the latest betas, the ePub script doesn’t work anymore. Regardless with which file I call it, I get only: $ mtxrun --script mtx-epub --make solo resolvers | caching | skipping 'files' for 'home:texmf' from '/Users/hraban/Library/texmf/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/trees/54be04d87dd160089f572b19cb5c97e9' (version mismatch) mtx-epub | unknown specificaton file for 'solo' Previously, you didn’t need to call it with any specification file, but only with a plain ConTeXt file like \setupbackend[ export=export.xml,xhtml=yes, ] \setupexport[ firstpage={koe.png}, ] \settaggedmetadata[ author={Hraban}, ] \starttext \startchapter[title={Chapter One}] \startsection[title={Section One}] \input tufte \stopsection \startsection[title={Section Two}] \input knuth \externalfigure[koe][width=\textwidth] \stopsection \stopchapter \stoptext An export.specification file was previously created by the script, I don’t know (anymore) for what. Calling the script with one of those also doesn’t do anything. Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)
