Does the languagetool extension work with 4.0?

I have upgraded to LibreOffice 4.0 (rc1 I believe) in Ubuntu 13.04.

However, I’m not sure if the language tool still works any longer, as it doesn’t seem to be integrating itself and checking my grammar as before.

Does this extension work with LibreOffice 4.0?

LanguageTool 2.0 works fine for me (LibreOffice · WinXP).
