Yes that's it for now, but there will be a new update soon (0.5) where they will add new content with Yasuka
will there be an update for the free version once the 0.5 comes out?
Yes, after the release of 0.5 - the current free version (0.3.91) will be replaced by the current paid version (0.4.91)
This will also be the case with the next versions.
