Obviously, i have it (i have had a beta version since May). It has one feature that i LOVE and have asked for several years: text wrapping INSIDE a shape (no more need for the script i coded a while ago). You can put text inside a vector shape or a selection!
The official release date is Aug 19, so i am planning a blog post on the 20th with a list of the features they added that i found very useful for me (not be a photo editor fan).
I think it is like any other version: some great new features, but also some bugs (based on their user forum, some people have some issues). But i know they are already working on a first patch for outstanding bugs and issues.
I think it is worth it and for work in tagging, card making and scrapbooking, i think the new features would make it worth it.
