The recent release of the Raspberry Pi 2 uses a newer version of the ARM architecture spec, the ARM Cortex-A7 uses ARMv7 whereas the previous model ARM11 uses ARMv6. The great thing about this is the majority of Linux distros already provide an Image for this architecture. More importantly, Fedora already have images. There is a slight caveat to the above statement however, that being they won’t just work with the Pi 2.
