There you can download the latest language pack from Downloads (generated on the fly from the system, which is always running on the latest version for tests). You can link to the forum and the bugtracker to get information or fixing minor bugs in the translation, if any.
The installation script (newdata.php) was also translated, so you can get a 100% Hungarian system if you do fresh install.
Some other modules are also in the work, XForum, PostCalendar and more. We are looking for voulnteers who will translate some more important modules and help the core team with ideas in the bugzilla!
