I haven't tried the new version, but the readme only states it's miscellaneous fixes. You'd think if something big (like extra titles or more events), he'd mention it.
So, I'm going to assume it's just spelling fixes and such.
On another note, the guys doing the comments on his blog are suggesting additions he could include. Most of them are interesting. A lot want further stuff to happen at the cafe, one wanted her to waitress around with a vibe. One wants Saki to feel the need to visit the female toilet... and have the vagrant impose on her.
But, anyway, I guess it'll be a while before any substantial upgrades come out. I quite like that the story isn't "finished", and you're just left to wander around. I just wish there were more town events you could play with.
