Yes, it has not been announced, because Lua 5 is still beta, and the library
has not been extensively tested for Lua 5. However, it seems to work fine on
my few tests.

You can download the patch here:

Hmm... that definitely sounds easier, but if you want to allow other people
to use your library from lua scripts, the module version would be
preferable. Why not just provide both options?
