The list of incompatibilites from 5.1 to 5.2 is in the reference manual
(currently at

Moreover, keep in mind that for Lua compiled with LUA_COMPAT_ALL on,
most of these differences vanish. (LUA_COMPAT_ALL is on in the default
makefile.) As I already pointed out, I think most of the work to migrate
from 5.1 to 5.2 will be to elliminate deprecated features from 5.0
which are not supported anymore in 5.2. (Such changes naturally lead to
"Clean" code.)
