What I've found (by comparing _G in 5.0 vs 5.1):

Removed:
   io.popen
   arg.n

Added:
  _PATH
     New name for LUA_PATH (now deprecated) used by 'require'

  string.reverse (s)
    returns a reversed copy of string 's'

  select (n, ...)
      If n is '#', returns number of variable arguments
        e.g. select('#',a,b,c,d,e) returns 5

      If n is a number, returns variable arguments [n,numvarargs]
        e.g. select(4,a,b,c,d,e) returns d,e

      -- function that prints it's args
      function varag(...)
        for i=1,select('#',...) do
          print(i, (select(i,...)))
        end
      end

  load
     No idea what this does. ^_^
