The main new features included in this release are: Features that were already available in previous releases: We got curious last month and checked out the YSlow! rating of our demo application. It got an awesome A rating (94 out of 100), but the funny thing is that we did nothing special. It's pretty much like the code you are already used to write. You may miss the content negotiation and passing objects as method arguments instead of attributes, both are in our TODO list. On the other hand, they are more than compensated by the current status of our tag library, which keeps getting better and better. If you are considering testing it, go ahead and give it a spin. Some architecture details can be checked out here and here. We would really welcome any feedback!
