Lua 5.3.1 (rc1) is now available at
http://www.lua.org/work/
The main changes are these:
- cleaner semantics for equality and order between floats and integers
- smaller memory overhead for short strings
- cache for 'lua_pushstring'
- own implementation for 'string.format("%a")' for C89 platforms
- table.move removed restriction that initial position should be positive
- bug fix (getlocal x yield in hooks)
- bug fix (suspended '__le' metamethod can give wrong result)
- bug fix (getlocal in return hooks)
