finding the kde version number

Used to be that when I wanted to find the KDE version number, I'd just open a KDE app and click on "About KDE" under the Help menu.

Open up Konsole in Debian Jessie and go to Help > About KDE and you'll see the following window, which shows the KDE version number:

In KDE apps in openSUSE Leap 42.1, which uses Plasma 5, the About KDE window no longer shows the KDE version number:

So, forget Help > About KDE.

Anyway, there's KInfoCenter (Main Menu > Settings > KInfoCenter). In Debian Jessie:

And, KInfoCenter in openSUSE 42.1:

So, I'm running KDE 4.14.2 in Debian Jessie and KDE Plasma 5.4.3 in openSUSE Leap 42.1, and KInfoCenter is still the best GUI way to quickly find the version number in KDE.
