Related issue #45

HEAD version already has a fix for lua-5.3. So a new version should be released to bring it to the users.

@brunoos do you plan to make a new release?

I want to work on some issues and PRs before the release.

But I should create a "alpha" tag if the code is compiling properly, so that we can have a milestone and a rocks.
