KDE Software Compilation 4.7 Released

I don't know if my attention span has gotten shorter or my willingness to dig for information has, but when I see announcements like this I immediately look for an overview video.

Gnome 3 used them to great effect. WordPress uses them with every release.

They are brilliant methods of summarizing, in minutes, why you should care about what this team has done.

I used to think screenshots were enough, but even now I'm annoyed enough at the time it takes to try and understand context in every screenshot to understand why some random popup/content-assist or hovering window is suppose to impress me (it probably WILL impress me, but I have to dig for context, which takes time).

I'm sure 4.7 has a slew of things in it that are drool worthy, but short of grinding through YouTube, I don't know what.

Doesn't the 'D' in KDE stand for 'desktop'? Which desktop users know what a 'software compilation' is?
