We're really excited for this new release. We learned a lot from releasing Foundation for Apps and applied those lessons to Foundation for Sites 6. The thing I'm most proud of as a member of the team, is how much awesome feedback from our community and many of the companies using Foundation went into making the next release even better for you all. We're going to be releasing an Alpha soon and will be looking for feedback. Hit me up at rafi at zurb .com if you're able to test it out and give feedback.
