The starter kits will be upgraded to the official version in the upcoming weeks. We need time to reflect the change of the API in the latest bits of the product, and test everything. We usually use the starter kits as part of the upgrade testing and process, but we still have to perform official upgrade once everything is finalized.
There will be no additional functionality delivered with the next version of the starter kits as our focus in terms of developer productivity is the new Software Development Kit that is going to be released next week.
