As of today, the JavaFX 8 Tutorial is available in six languages and two are beeing translated right now! English, Portuguese, Spanish, Chinese, Russian, and Indonesian. French has a partial translation and someone has just sent a pull request today for an Italian translation.
The translated tutorials still need an update to reflect the changes described above. So, if you care about one of the languages and would like to help out, let me know.
To see what has changed, you could take a look at this commit.
