That's also my biggest problem with Lua.
I tried other script languages(Groovy, Ruby, JavaScript, Perl) before 
Lua and it is for me the best script language that I know.
It has some 'strange' things I can life with, like ~= instead of != or 
that the first value in a Array/Table is 1 and not 0, but the 
differences between the Lua Versions 5.1, 5.2 and 5.3 are really 
frustrating.
For me it is hard to understand why for example functions(log()) in the 
standard math.library are changing between the versions.
It is also a big problem that we have a separation between LuaJIT and 
Lua5.2 / Lua5.3.
Currently I am using 5.2 but I am thinking permanent to switch to LuaJIT 
so I have a more solid base.
I hope that 5.3 will be more stable.

Alexander
