Maybe I've missed it somewhere, but what is the difference between 1.86 and 1.87? Should I bother upgrading or just wait til V2?

I'm a new user but like the app so far, though it is missing some features found on other packages, I can see that the software is still fairly new with a lot of ongoing development. Developers who are serious about improving products will get my purchase any time over ones who just sell something "as is" and don't care about the users.
