"Joymax is also committed to frequent free updates to the game, reminiscent of traditional expansion packs. These include new lands, levels and skills for players to explore and learn. On top of that, there are the regular small updates and bug fixes.
Currently, they're hard at work planning a new update that is due out in the next couple months, likely before the end of the year. Unfortunately, at this time, they are still not revealing any details of what it include."
