What's up with Rebelle 7 or 6?

So what’s up with Rebelle? I can’t find anything related to this Software on piracy forums, the only thing I found is that there is a older verson on softarchive.

For context Rebelle is a painting software that simulates traditional tools.

I also don’t want to torrent just to be safe even with a vpn. Does someone know why there isn’t a new version available and when there is, does someone know where?
