LaTeX source files more than 5 years old!. So the limit is five years (but only for the latex kernel). The version date of my (current) latex.ltx ist \edef\fmtversion{2011/06/27} > Or is XeTeX not intended to be used in these environments? I would say that if your latex is more than five years old, your xetex binaries and packages aren't up-to-date either. And as xetex is rather young this can be quite a problem. Regardless if you want to ship out only xetex documents or xetex documents + binaries: You should be aware that other people can have up-to-date systems and so you should make tests on such systems too (and just in case you don't know: you can't use a fmt generated by one xetex version with another xetex version). -- Ulrike Fischer -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
