Thanks to everyone that helped make this release happen!
Also, Ross's name is in the blog post. If you take a look at the Github repo you can see that both Francisco and Tom have recently put a lot of work into this release as well.
I am not experienced with gwt or cappucino, but it seemed that they aimed similar things, developer not needing to deal with html, css, dom etc.
Actually, it seems the real contender is sproutcore here.
I'm not quite sure what you mean by "the real contender" though.
Each of the above has their strengths and weaknesses, and there are many more frameworks than I can list at the moment, but even with the select list above we can see there are many more contenders in this space than just Cappuccino, Sproutcore, and GWT.

Thanks for the list :)

Developers well versed in Mac development have years of accreted knowlege of design patterns, common mistakes, and best practices, a great swath of which apply also to Cappuccino development.
I'm not talking about trivial things like how buttons clicks trigger functionality, or how to show a dialog; those can be learned in a short time in just about any language/framework.
I mean things such as: how to do robust undo/redo involving complex object graphs, how to build performant UIs that manipulate tens or hundreds of thousands of data records, or how to design complex interfaces with dozens of windows and model-view-conroller sets that avoid tight coupling and remain reasonable to refactor and maintain over time.
Building up this type of knowledge really does tend to take months, if not years, in just about any development environment you care to name. So the fact that Cappuccino leverages the experience that you or your team already has--in addition to doing the work of providing a framework and toolkit for UI and app logic, and abstracting away the DOM--is a tremendous advantage.
This is true only for some people, obviously; it's not a benefit if you don't already have that kind of experience (although IMO cap should still be on your short list of things to evaluate for new web apps). But if you do have significant Mac development experience, and especially if you're working on a short 8 or 12 month development cycle (say some company's internal HR admin app, or something like that), it can be the difference between hitting your deadline or being months late because of an accumulation of unforeseen issues and learning experiences along the way.
So I, for one, am heartily thankful to the Cappuccino team.
A fairly recent impressive Cappuccino application is PicsEngine:
Also check out GitHub Issues which very nicely demonstrates the state of the art TableView widget:
Archipel is more of a technical app highlighting a ton of various '2.0' techs in one app unified by the Cappuccino experience:
Edit: I Googled "Objective-J license" to answer my own question -- the answer was LGPL. Awesome!
