We have just added the last feature on the list to the preview 2 release, which is the release you are going to use on the boards we are shipping to you. The feature is for enabling application protection, which simply locks out your application from being pirated. Once the device is locked, it can only be completely erased, or it can be updated though secure in-field update. Note that this features disables the debugging functionality as well.
We are now checking one last thing and the kits will ship out this week if no surprises arise. As you seen in the newsletter, they are all ready to go.
The goal is for you to have docs/firmware/hardware to use next week.
