I am using an up-to-date version of MikTeX. As soon as I compile a document with LuaLaTeX and including the package polyglossia I get two warnings:

  1. Module luaotfload-main warning: LuaTeX v0.76 is old, v0.79 or later is recommended.
  2. LaTeX warning: "xparse/redefine-command" - Redefining document command \oldstylenums with arg. spec. 'm' on line 144. (-> fontspec-patches.sty)

I would like to get rid of those.

    Well, you can always download the latest versions yourself.

  • I would like to get rid of those. -- You can get rid of the first one by updating you Luatex engine.

    @phg: miktex has no update for luatex yet. Someone would have to make a feature request. Is the update needed for something in luaotfload?

  • None that I know of but I can only support the Luatex version in TeX Live as well as the latest SVN trunk. But it’s not that big of a deal: after all, we’re talking about a harmless warning, not an error.

It's more a hack than a fix, but if you only want to get rid of the LuaTeX version warning and maybe wait for an official update from MikTex, you can edit the file MiKTeX\tex\luatex\luaotfload\luaotfload-main.lua and comment the warning out:

--[[ starts a comment block, --]] closes it.

if tex.luatexversion < min_luatex_version then
--[[
    warning ("LuaTeX v%.2f is old, v%.2f or later is recommended.",
             tex.luatexversion  / 100,
             min_luatex_version / 100)
--]]
    --- we install a fallback for older versions as a safety
    if not node.end_of_math then

Just install Texlive 2014 instead of miktex.
