Any SDK that is created is now standalone and can be deployed by itself.
configure will now build Qt for you if you pass -build-qt and Qt 4.3 or higher is not installed on your system. A -force-build-qt switch also exists to force this behaviour (eg. so that you can create an SDK without a dependency on Qt).
Most projects have been updated to use the preferred style and to remove legacy code.
Resources are now stored in the project that owns them. The server still handles the global translations, it finds files by looking for projects that set UNIFIED_NCT_LUPDATE=1. This has a significant impact on existing devices as any override files must be moved so that the build system will find them.
Server projects are now enabled via SERVER_PROJECTS. Server projects can now live outside src/server.
Known Issues
Building for an x86_64 target does not work.
Devices need to have override files moved. This is most noticeable for files in etc.
