[opensuse-factory] what's new in M3

Heya all, Last time I wrote the M2 article and we all know what happened. Yes, we did get attention. No, it wasn't very accurate - the vast majority of stuff I talked about (after diggin' through mailing lists and other places) wasn't included yet. So, I want to better my life. And need you all for that: what do I talk about? /Jos
