Just wanted to share that Lua 5.2.0 got released. I dunno if the new release has things that many people had asking for or not. Here's the changelog :-
- {l Code}: {l Select All Code}

Here are the other changes introduced in Lua 5.2:
Language
no more fenv for threads or functions
tables honor the __len metamethod
hex and \z escapes in strings

order metamethods work for different types
no more verification of opcode consistency
hook event "tail return" replaced by "tail call"
empty statement
break statement may appear in the middle of a block
Libraries
arguments for function called through xpcall
optional 'mode' argument to load and loadfile (to control binary x text)
optional 'env' argument to load and loadfile (environment for loaded chunk)

optional base in math.log
optional separator in string.rep
file:write returns file

new metamethods __pairs and __ipairs
new option 'isrunning' for collectgarbage and lua_gc
frontier patterns

new functions lua_absindex, lua_arith, lua_compare, lua_copy, lua_len, lua_rawgetp, lua_rawsetp, lua_upvalueid, lua_upvaluejoin, lua_version.
new functions luaL_checkversion, luaL_setmetatable, luaL_testudata, luaL_tolstring.
lua_pushstring and pushlstring return string
nparams and isvararg available in debug API
new lua_Unsigned
Implementation
max constants per function raised to 226
generational mode for garbage collection (experimental)
NaN trick (experimental)
internal (immutable) version of ctypes
simpler implementation for string buffers
parser uses much less C-stack space (no more auto arrays)
Lua standalone interpreter
new -E option to avoid environment variables
handling of non-string error messages
Of course as it is a .0 release most of the devs. would probably wait it to mature a bit more but still there might be some feature that might make it enticing for game developers. I have no idea, I am just a gamer :P
