AppFramework, Ionic and Framework 7 support in Designer has been deprecated in this release, and will be removed from the XDK in the future. You can see more information here https://software.intel.com/en-us/xdk/docs/release-notes-information-intel-xdk
As previously announced and noted in the release notes, future editions of the Intel XDK will focus on the development of IoT (Internet of Things) apps and IoT mobile companion apps. Since we introduced the Intel XDK IoT Edition in September of 2014, the need for accessible IoT app development tools has increased dramatically. At the same time, HTML5 mobile app development tools have matured significantly. Given the maturity of the free open-source HTML5 mobile app development tools, we feel you are best served by using those tools directly.
