[CentOS] Centos 7: Notification of available updates in KDE?

Hi,

I recently upgraded from CentOS 5 to 7.  I have been running KDE.  In 
version 5, if there was a pending update, an icon would appear in the 
panel, notifying about the update.
There is no such icon in CentOS 7 - KDE 4.

Is there a way to get this very convenient function?

Thanks
Frank
