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?

You could try installing apper (which includes an update notification applet) from epel7 repo
