To mention what would be most impacted would be the SecureHandler system as it relies entirely on being able to create independent secure environments.


8.1 – Changes in the Language
  • The concept of environment changed. Only Lua functions have environments. To set the environment of a Lua function, use the variable _ENV or the function load.

    C functions no longer have environments. Use an upvalue with a shared table if you need to keep shared state among several C functions. (You may use luaL_setfuncs to open a C library with all functions sharing a common upvalue.)

    To manipulate the "environment" of a userdata (which is now called user value), use the new functions lua_getuservalue and lua_setuservalue.

8.2 – Changes in the Libraries
  • Functions setfenv and getfenv were removed, because of the changes in environments.
