This is a work version. All details may change in the final version.

Here are the main changes since the previous work version:
- module and luaL_register deprecated, replaced by luaL_newlib and luaL_setfuncs.
- new function luaL_requiref.
- caching of Lua closures for resue.
- version-specific environment variables (LUA_PATH_5_2, etc.).
- new class '%g' in patterns.
- debug.getlocal gets parameter names of inactive functions.
- new functions lua_tonumberx and lua_tointegerx.

The manual has been updated but is still incomplete.

The complete diffs are available at
	http://www.lua.org/work/diffs-lua-5.2.0-work3-work4.txt

The diffs are still a bit large because of changes in the manual.

All work versions are available at

All feedback welcome. Thanks.
