Hi, as people reported problems with mathastext under lualatex I have become aware that \luatexUmathcharnumdef etc... have been removed and \Umathcharnumdef etc... must be used instead.
as I didn't find the info immediately I am asking here: how should I test (version number, date etc...) when one should use \luatexUmathcharnumdef and when on should use \Umathcharnumdef ? or perhaps \Umathcharnumdef was always ok ? I would like to not break people's old installation thus I would be glad to use \Umathcharnumdef if I am told it works with all earlier lualatex best wishes Jean-François
