Hello all,I don't know how LuaTeX is supposed to follow the development of Lua, but you might be interested to learn about the incompatibilites between Lua 5.1 and 5.2 (alpha):
http://www.lua.org/work/doc/manual.html#8Most importantly, module() is deprecated, so packages should sooner or later do without. And watch out the move from unpack() to table.unpack().
Best, Paul
