Among the changes you will find a new generic licence which is based on international laws instead of the US copyright like the former generic licence was. Also a by-sa compatibility list was created to make it possible to mix content under by-sa with content under another, but compatible licence. And last but not least, Debian and MIT should be happy now as well. You can find more detailed information at Creative Commons Version 3.0 Licenses A Brief Explanation."
